The constant-product FPMM needs only +integer multiplication and division, is natively unit-testable +(`math.rs` has no `Env` dependency at all), and is mirrored line-for-line +in Python and TypeScript for cross-language property testing. LMSR is +tracked as a possible alternative curve — see +`oracledesk-stellar/docs/wave-issues/03-lmsr-alternative-curve.md`. + +**Why commit to a resolution rule at market creation?** +Without it, a market's creator could watch how the crowd prices an event +and only then pick (or negotiate) a resolution rule favoring a different +outcome. A hash commitment fixed before trading opens removes that +degree of freedom entirely — see +[ADR 0001](oracledesk-stellar/docs/adr/0001-resolution-commitment.md). + +**Why does resolver generate a client from market-core's compiled wasm +instead of depending on its Cargo crate?** +A crate dependency compiles fine natively but breaks the wasm build: +`#[contractimpl]` exports every contract entrypoint as a `#[no_mangle]` +wasm symbol, and two `#[contract]` structs in one compiled wasm collide. +See [ADR 0002](oracledesk-stellar/docs/adr/0002-cross-contract-calls.md). + +**Why x402 for reasoning traces?** +At ~$0.01 per read, traditional payment rails don't make sense for casual, +per-trace access. x402's exact-payment scheme integrates as one middleware +line on an Express route, and the trace is only served after its fetched +content is re-hashed and checked against the on-chain record — so a +subscriber never has to trust the API server's word that a trace is +authentic. + +--- + +## Built With + +- [Soroban](https://developers.stellar.org/docs/build/smart-contracts/overview) / [soroban-sdk](https://crates.io/crates/soroban-sdk) — Rust smart contracts +- [Stellar CLI](https://developers.stellar.org/docs/tools/cli) — build, deploy, invoke +- [x402](https://x402.org) — HTTP-native micropayments for reasoning traces +- [@stellar/stellar-sdk](https://www.npmjs.com/package/@stellar/stellar-sdk) — TypeScript contract clients and signing +- Python 3 — the FPMM math's cross-language property-testing reference + +--- + +*OracleDesk — ported to Stellar/Soroban.* diff --git a/docker-compose.yml b/docker-compose.yml index f80a4601..3d37e4b0 100644 --- a/docker-compose.yml +++ b/docker-compose.yml @@ -1,71 +1,71 @@ -# docker-compose.yml for multi-instance x402 deployment with Redis coordination -version: '3.8' - -services: - redis: - image: redis:7-alpine - ports: - - "6379:6379" - command: redis-server --appendonly yes - volumes: - - redis-data:/data - healthcheck: - test: ["CMD", "redis-cli", "ping"] - interval: 5s - timeout: 3s - retries: 5 - - x402-1: - build: - context: . - dockerfile: Dockerfile.x402 - environment: - X402_STORE: redis - REDIS_URL: redis://redis:6379/0 - X402_LOCK_TTL_MS: "30000" - X402_LOCK_WAIT_MS: "1000" - X402_RESULT_TTL_MS: "600000" - LOG_LEVEL: info - PORT: "3000" - METRICS_PORT: "9090" - ports: - - "3000:3000" - - "9090:9090" - depends_on: - redis: - condition: service_healthy - healthcheck: - test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:3000/health"] - interval: 30s - timeout: 5s - retries: 3 - restart: unless-stopped - - x402-2: - build: - context: . - dockerfile: Dockerfile.x402 - environment: - X402_STORE: redis - REDIS_URL: redis://redis:6379/0 - X402_LOCK_TTL_MS: "30000" - X402_LOCK_WAIT_MS: "1000" - X402_RESULT_TTL_MS: "600000" - LOG_LEVEL: info - PORT: "3001" - METRICS_PORT: "9091" - ports: - - "3001:3000" - - "9091:9090" - depends_on: - redis: - condition: service_healthy - healthcheck: - test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:3000/health"] - interval: 30s - timeout: 5s - retries: 3 - restart: unless-stopped - -volumes: - redis-data: +# docker-compose.yml for multi-instance x402 deployment with Redis coordination +version: '3.8' + +services: + redis: + image: redis:7-alpine + ports: + - "6379:6379" + command: redis-server --appendonly yes + volumes: + - redis-data:/data + healthcheck: + test: ["CMD", "redis-cli", "ping"] + interval: 5s + timeout: 3s + retries: 5 + + x402-1: + build: + context: . + dockerfile: Dockerfile.x402 + environment: + X402_STORE: redis + REDIS_URL: redis://redis:6379/0 + X402_LOCK_TTL_MS: "30000" + X402_LOCK_WAIT_MS: "1000" + X402_RESULT_TTL_MS: "600000" + LOG_LEVEL: info + PORT: "3000" + METRICS_PORT: "9090" + ports: + - "3000:3000" + - "9090:9090" + depends_on: + redis: + condition: service_healthy + healthcheck: + test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:3000/health"] + interval: 30s + timeout: 5s + retries: 3 + restart: unless-stopped + + x402-2: + build: + context: . + dockerfile: Dockerfile.x402 + environment: + X402_STORE: redis + REDIS_URL: redis://redis:6379/0 + X402_LOCK_TTL_MS: "30000" + X402_LOCK_WAIT_MS: "1000" + X402_RESULT_TTL_MS: "600000" + LOG_LEVEL: info + PORT: "3001" + METRICS_PORT: "9091" + ports: + - "3001:3000" + - "9091:9090" + depends_on: + redis: + condition: service_healthy + healthcheck: + test: ["CMD", "wget", "--no-verbose", "--tries=1", "--spider", "http://localhost:3000/health"] + interval: 30s + timeout: 5s + retries: 3 + restart: unless-stopped + +volumes: + redis-data: diff --git a/oracledesk-stellar/.env.example b/oracledesk-stellar/.env.example index af5575a3..f765a70f 100644 --- a/oracledesk-stellar/.env.example +++ b/oracledesk-stellar/.env.example @@ -1,197 +1,197 @@ -# Copy to .env and fill in.

Run `make interface-check`, `make lint`, `make test`, and + `CARGO_TARGET_DIR=target cargo test --locked --manifest-path scripts/interface-manifest/Cargo.toml`. + Override `INTERFACE_BASE_REF` when comparing to a different target. + +A named struct's field names determine its symbol-keyed XDR map; declaration +order does not. Tuple positions and function argument order do matter. Union +additions warn about exhaustive consumers. Renaming numeric error cases warns +about generated TS messages. Types reachable from resolver `ResolutionSpec` +**and** `ResolutionSpecV2` are hash-critical: a semantic change is breaking and +carries the ADR 0001 flag. Review commitment migration before deploying it. + +The tool attributes imported types using `scripts/interface-manifest/imports.toml` +(the WASM spec drops their library origin). Update that map when adding a public +`contractimport!` type. Every package exporting a changed type needs its own +version bump, including consumers; each package takes the maximum required bump, +never one bump per inherited field/type. This avoids compounding shared changes +while keeping downstream versions truthful. Hash roots live in `roots.toml`. + +An absent base manifest is an initial release and requires a nonzero version plus +an initial changelog, not an artificial breaking-change report. CI compares +against the PR base branch and also rejects stale generated manifests. GitHub +runs the workflow at the repository root; the nested workflow is retained for +standalone use of `oracledesk-stellar/`. diff --git a/oracledesk-stellar/Cargo.lock

- } -} \ No newline at end of file +//! Pure integer math for a binary fixed-product market maker (FPMM). +//! +//! No Soroban types in here, so `cargo test` exercises it natively and +//! `model/fpmm_model.py` mirrors it line by line for property testing. +//! +//! Conventions +//! - All amounts are non-negative `i128` in collateral base units. +//! The number of decimals is not fixed: deployers pass any SEP-41 +//! token with decimals in `0..=18`. Economic bounds (`min_seed`, +//! `max_sets`) are derived from the collateral's decimals via +//! `bounds_for_decimals`. At 18 decimals the product of two +//! quantities can reach ~1e52, well beyond `i128`, so the +//! multiply-divide helpers use 256-bit intermediates (`wide` module). +//! A quotient that fits in `i128` is always returned exactly. +//! - Rounding always favours the pool: fees round up, shares out round down, +//! shares in round up. This is what keeps the pool invariant `k = r_yes * r_no` +//! non-decreasing and blocks dust-splitting attacks. +//! - Additions that could in principle overflow are `checked_add`. At the +//! largest supported decimals (18), `max_sets = 1e26` and sums of two +//! such reserves stay far below `i128::MAX`. +//! - See `docs/fpmm-economics.md` for the proofs of the rounding, LP-loss and +//! no-arbitrage claims made here (checked by `model/fpmm_bounds.py`). +//! - `MAX_SETS` bounds market size so that any product of two quantities +//! (both <= 1e15) is <= 1e30, far below `i128::MAX` (~1.7e38). Every +//! multiplication is still `checked_*` as a second line of defence. +//! +//! Headroom for `calc_sell_shares`: with b = shares_in + r_sold + r_other +//! and every term <= MAX_SETS = 1e15, b <= 3e15 and b^2 <= 9e30. The +//! discriminant D = b^2 - 4*r_other*shares_in fits in u128 (max ~3.4e38). +//!

Mainnet and testnet are both at 3_110_400 ledgers +//! (180 days) today, so a market further than 90 days from close is capped +//! at the network maximum and needs activity or the keeper +//! (`docs/wave-issues/14-storage-ttl-keeper.md`) to outlive one bump. +//! - Persistent entries are only re-extended once their remaining TTL has +//! dropped below half the target (`threshold_for`), so a busy hot path +//! does not pay an extension write on every call. +//! +//!

Final report | ✅ This file | | - -## What's fully verified (command output exists for all of these) - -- `cargo fmt --check`, `cargo clippy --workspace --all-targets -- -D - warnings`, `cargo test --workspace` (40 tests across `market-core`, - `resolver`, `reasoning-registry`, `treasury`) — all exit 0. -- `stellar contract build` produces all four `.wasm` files cleanly, with no - spec warnings (the `experimental_spec_shaking_v2` soroban-sdk feature was - needed to get `Outcome`/`Category` properly represented in - `resolver`'s/`treasury`'s own contract spec — see ADR 0002). -- `python3 model/fpmm_model.py` passes (known-value checks against the same - worked examples as the Rust tests, a property test, and a - `gross_for_shares`/`calc_sell` round-trip check). -- `cd agents && npm test` — 24 tests pass, including the same known-value - and property checks in TypeScript/BigInt (`agents/core/fpmm.ts`). -- `cd x402 && npm test` — 5 tests pass, including the new registry-backed - `TraceRepository`. -- Live testnet deployment and the full demo loop - (`scripts/deploy-testnet.sh`, `scripts/seed-market.sh`, - `scripts/demo.sh`) — real transaction hashes were produced for: market - creation, a trade, signer attestation, resolution finalization, trace - publication, and hash verification. Ran twice (once building the scripts - interactively, once via the finished `scripts/demo.sh`) with consistent - results. -- **The resolution-commitment design (ADR 0001)** was validated on live - testnet, not just in unit tests: `treasury.agent_create_market` was - called with a `resolution_hash` computed off-chain by - `scripts/spec-hash/`, and `resolver.register_signer_spec` accepted the - matching revealed spec — the hash genuinely round-tripped through real - XDR encoding on a real ledger. -- **The treasury cross-contract auth fix (ADR 0002, `authorize_token_pull`)** - was validated three ways: (1) a unit test using targeted `mock_auths` - (not `mock_all_auths`, which would hide the bug); (2) that same test was - manually re-run with the fix commented out, confirmed to fail with - `HostError: Error(Auth, InvalidAction)` / "Unauthorized function call", - then confirmed to pass again with the fix restored; (3) the real, - unmocked testnet transaction for `agent_create_market` succeeded, which - would have failed with the same auth error had the fix been wrong. -- **All four** `packages/bindings/*` packages: generated, then `npm install - && npm run build` completed with no errors for every one of them - (`market-core`, `reasoning-registry`, `resolver`, `treasury`) — a full - round-trip, not just generation. `resolver`'s and `treasury`'s installs - were slower (each ~4 minutes against this sandbox's npm registry) and so - were run later in the session than the other two, but all four are now - confirmed. - -## What's implemented but not fully round-trip verified - -- **x402's registry-backed `TraceRepository`** - (`x402/registry-trace-repository.ts`): unit-tested with a - dependency-injected fake reader (its real interface, verified against the - actual generated `get_trace` signature). Attempting to run the real - server against the live deployed `reasoning-registry` failed — but the - failure is an environment issue, not a code issue: **Node's own outbound - `fetch` to `soroban-testnet.stellar.org` times out at the TCP level in - this sandbox** (`ETIMEDOUT` / `ENETUNREACH`, reproduced with a bare - `node -e "fetch(...)"` with no OracleDesk code involved at all), while - `curl` to the identical URL and the Rust `stellar` CLI itself both work - fine throughout this same session. This looks like a sandbox network - policy specific to Node's raw socket connections, not a bug here — but it - means the actual RPC round-trip for this path is unverified in this - environment. Whoever runs this outside this sandbox should confirm it - directly. -- **Agents' live mode** (`agents/stellar/adapter.ts` with - `mode: "live"`, i.e. `AGENT_MODE=live` for the CLIs): implemented, - type-checked against the real bindings, and structurally exercised in - dry-run mode end to end. Never run in live mode — that would need the - same Node→testnet RPC path just noted as unverified, plus a funded - agent secret key wired through `AGENT_SECRET_KEY`. -- **`quote_sell`/`collateralOutForShares` against a live contract quote**: - the property test in both `model/fpmm_model.py` and - `agents/core/fpmm.test.ts` verifies the off-chain math against itself - (forward `calc_sell` vs. the `collateralOutForShares` inverse), which is - what the design brief asked for ("add a test against the contract - quote") in spirit — but it was not additionally checked against a live - `market-core.quote_sell` call on testnet with real reserves. - -## Blocked / not attempted - -- **Reflector (SEP-40) price-mode resolution on live testnet**: `resolver`'s - `PriceThreshold` mode is implemented and unit-tested (with a mock - reflector), but no real testnet Reflector contract address was used - anywhere — there was no way to look one up and verify it against - Reflector's own current docs in this session (no browsing tool was - used for this). The demo uses **signer mode** instead, which needs no - external oracle. See `docs/wave-issues/05-reflector-feed-discovery.md`. -- **A real testnet USDC issuer** (e.g. Circle's): not used. `scripts/ - deploy-testnet.sh` deploys a **self-issued** test "USDC" (a real SEP-41 - Stellar Asset Contract, 7 decimals, matching the design doc) rather than - guessing at a real issuer's address. This is called out as a - `TODO(maintainer)` in `scripts/deploy-testnet.sh` and `.env.example`. -- **Actually buying a trace through x402** (payment settlement via a real - facilitator): not attempted. No x402-on-Stellar facilitator URL is known - or hardcoded anywhere in this repo; finding and verifying one needs - browsing x402's current docs, which this session didn't do. `x402/`'s - code path up to "would this trace be served" (hash verification) is - tested; the payment middleware itself is `@x402/*`'s own code, unmodified - here. -- **CI has never actually run** (no GitHub Actions run occurred — this repo - was never pushed). `.github/workflows/ci.yml` mirrors every command this - file claims was run locally, but "the workflow file is correct" is a - weaker claim than "the workflow ran green," and it's flagged as such. - -## Changed from the original design, and why - -- **Treasury's public API**: the design doc describes - `agent_create_market`/`agent_buy`/`agent_sell` calling market-core "as - the trader/creator itself." The *inherited* code had a completely - different, advisory-only `authorize_trade`/`close_trade` pair that never - called market-core at all. This was a real gap (the on-chain caps didn't - cap anything), not a style choice, so it was replaced rather than kept - alongside the new functions — see the commit that did this and ADR - references in `contracts/treasury/src/lib.rs`. -- **Cross-contract calls**: the design doc suggested either - `contractimport!` or a Cargo dependency, "pick the simplest that builds." - A Cargo dependency does not build to wasm (duplicate `__constructor` - export — see ADR 0002), which the design doc didn't anticipate. Switched - to `contractimport!` for both `resolver` and `treasury`. -- **Resolution spec registration is not admin-gated.** The original - resolver had `configure_price`/`configure_signers` as admin-only setters. - Per the resolution-commitment design (ADR 0001), the correct gate is the - cryptographic commitment, not caller identity — anyone can reveal a spec - that hashes correctly, since only whoever picked it in the first place - could have produced a match. -- **Guardian functions added** (`resolver.cancel_proposal`, - `resolver.guardian_void_market`): the design doc's Attested mode - description mentions "a guardian can cancel a proposal or void the market - during the window," but no such functions existed in the inherited code. - Added as thin, admin-gated wrappers. -- **`agents/core` is not a port** of `oracledesk-contracts/agents/*.ts`. - Those files turned out to contain only EVM/Circle/Polymarket *execution* - plumbing (ABI encoding, Circle Developer-Controlled Wallets, EIP-712 - order signing) — exactly what the design brief says to remove, and - nothing chain-agnostic to actually carry over. `agents/core/strategy.ts` - is a fresh, minimal implementation of the two described roles. - -## TODO(maintainer) - -Decisions only a human maintainer should make, left as `TODO(maintainer)` -markers in the files themselves: - -- `SECURITY.md` — an expected triage/response timeline for reports. -- `CODE_OF_CONDUCT.md` — a direct contact channel alongside GitHub's - security-advisory reporting path, if wanted. -- `CONTRIBUTING.md` — an expected PR review turnaround. -- `scripts/deploy-testnet.sh` / `.env.example` — whether to switch the - testnet collateral token from the self-issued test USDC to Circle's real - testnet USDC issuer (needs verifying their current testnet address). -- `.env.example` — the x402-on-Stellar facilitator URL to use for real - payment settlement (none is hardcoded or guessed anywhere in this repo). - -## Known limitations - -- **Testnet only, unaudited.** Nothing here has been professionally - reviewed; do not deploy to mainnet. -- **No indexer.** Soroban RPC's event retention window is short; anything - needing history beyond it has no data source yet (see - `docs/wave-issues/06-event-indexer.md`). -- **Agent-vs-agent liquidity** is unbounded: nothing stops multiple - independent agent deployments from trading against the same - `market-core` markets. The treasury's caps bound one deployment's own - risk, not systemic market behavior. `agents/sim` now quantifies this - (see `docs/simulation.md`, experiment B): with k identical deployments, - capital at risk grows linearly in k while total profit does not. -- **Unredeemed shares expire after the redemption window.** Each market - snapshots a redemption horizon at creation (default 365 days; the admin - default is bounded to 180–1825 days). Once `finalized_at + horizon_secs` - has passed, anyone can call `finalize_market`, which sweeps the market's - **entire** remaining balance — expired user claims, void rounding dust, - any unclaimed LP remainder and accrued fees — to the treasury and closes - redemption (`redeem`/`claim_pool_remainder` then revert with - `RedemptionClosed`). Redeeming before the deadline always pays the exact - `settle_value`; expired claims go to the treasury, not the LP. Markets - created before this `SettleState` bookkeeping (issue #14) have no deadline - and cannot be finalized (`NotSupported`), and stay redeemable through the - old paths. A market waiting on a multi-year deadline can be - TTL-archived before it is finalized and needs a restore (or the keeper, - `docs/wave-issues/14-storage-ttl-keeper.md`) first; the deadline itself is - on-chain state, so a late finalization is still exact. -- **The TWAP ring keeps only the most recent 16 observations.** Each - observation is written per trade timestamp, so 16 distinct-timestamp trades - supersede the creation point: `observe`/`twap` windows that reach further - back than the surviving ring revert with `ObservationTooOld` rather than - returning a value. Windows that extend past the newest observation keep - averaging the last traded price (the accumulator extends - counterfactually), including past `close_time` until a resolver action. - `twap` divides with floor rounding; off-chain mirroring code must floor - identically. Markets created before the accumulator (issue #11) return - `NotSupported` from `observe`/`twap`/`price_cumulative`, and an archived - `Oracle`/`Obs` entry needs a restore like any other entry. -- **Expiry cannot help an oracle the creator controls.** `expire_market` - voids unresolvable markets 30 days after close, but a creator who commits - to a feed they control can still decide the outcome of a *resolvable* - price market; the commitment does not bind oracle identity (ADR 0001, - "Liveness fallback"). -- **Admin keys are rotatable and can be a multisig or the governance - timelock** (ADR 0007, ADR 0008). Every contract now has - `propose_admin`/`accept_admin`/`cancel_admin_transfer` with a seven-day - expiry; `new_admin` may be a classic multisig account, a smart-account - multisig (`CustomAccountInterface::__check_auth`), or the timelock. - `scripts/deploy-testnet.sh` can point the four core contracts at the - timelock from birth (`USE_TIMELOCK=1`), and `scripts/wire-timelock.sh` - migrates an existing deployment through the two-step handover. - - Residual: the deploy still defaults to the deployer EOA as admin - (`USE_TIMELOCK=0`), because the timelock makes the deploy script's own - admin setup calls wait out the delay and CI cannot fast-forward it. - Turning the flag on, or running `wire-timelock.sh`, is the operator's - step. See - `docs/adr/0006-authenticated-wiring-and-deterministic-deploy.md` for the - resolver/treasury wiring handshake. -- **Resolver/treasury wiring is authenticated** (ADR 0006). `market-core` - proposes, the receiving contract proves it is configured for this - market-core, and change events are emitted; the old unauthenticated - `set_resolver`/`set_treasury` are gone. Deploys are deterministic - (`--salt`), and `scripts/migrate-market-core-wiring.sh` upgrades a - pre-handshake deployment. -- **Multi-step flows are atomic through the router** (ADR 0009): - `create_and_reveal_{signers,price}`, `reveal_spec`, and - `buy_and_publish_trace`, so a market cannot exist without its rule and a - trade cannot drop its reasoning trace. -- **Residual admin blast radius.** The treasury's config, price policy and - agent registry are timelocked (loosening waits `config_delay`, tightening - is immediate), which bounds what a compromised admin can unlock for the - *agents*; it does not cover `set_paused`, `set_successor` + - `migrate_market` (which moves positions out of the vault), or any other - contract's admin. Under the deferred timelock default (above) that - exposure is still live on testnet. -- **Treasury vault NAV is conservative, not mark-to-market.** Directional - exposure in open markets counts as zero, so deposits are slightly cheap - and withdrawals slightly expensive while positions are open; positions - opened before a lazy migration from the pre-vault layout, or received by - a successor treasury via `migrate_market`, are not in the open-market - index and count as zero until redeemed. See - `docs/adr/0005-treasury-vault.md` for the residual risks (LP floor moved by - rebalancing trades, fees swept just after a deposit). -- **`treasury`'s per-market cap is cumulative and never decreases** (even - after `close_trade`) — this is the existing, intentional design (a - lifetime cap on capital ever committed to one market), documented in - `contracts/treasury/src/lib.rs`'s comments, but worth stating here since - it's easy to misread as a bug. The separate **net** cap - (`max_net_exposure`, see `docs/architecture.md` "Caps") is what bounds - capital currently deployed; sells and redemptions free it. -- **Price snapshots must be taken within oracle retention.** `snapshot_price` - lets resolution outlive the oracle's bounded history, but only if someone - calls it while the `close_time` record is still retained; there is no - keeper doing so automatically yet. - -## Reproducing this - -```bash -make setup && make build && make lint && make test -make deploy-testnet # idempotent — safe to re-run -make demo # full create -> trade -> resolve -> trace -> verify loop -``` - -See `README.md` for prerequisites. - -## Contributor addendum: interfaces and x402 (#77–#80) - -All six contracts now have deterministic WASM-derived interface manifests, -initial 0.1.0 bindings versions and changelogs. The standalone interface-manifest -tool classifies semantic changes, flags resolver commitment types, and enforces -version/changelog policy against the PR base. Golden tests decode committed -cross-contract WASMs and all six freshly built artifacts. The root CI workflow -now runs the formerly nested checks and the new interface policy. - -x402 multi-network routing and the authorization-only prepare → verify → settle -→ deliver order are covered with a protocol-faithful recording HTTP facilitator. -Tests cover both networks/API keys, stock-SDK 402 compatibility, trace failures -and bounded timeouts, tampered requirements, durable-before-settle failures, -concurrent duplicates, SQLite and memory ledger contracts, free replay and -indeterminate settlement. These replace the earlier statement that payment -ordering depends solely on untested SDK middleware. Real facilitator settlement -and mainnet payment round-trips remain unverified; tests make no real payments. - -The upstream baseline had duplicate treasury error discriminants and stale -fixtures after merges. Newly introduced conflicting errors were moved to unused -44–58, preserving committed 1–33 codes. Treasury fixtures now respect market-core's -100 USDC seed minimum, explicit sell slippage bounds, final settlement before -PnL realization, and per-invocation event lifetimes; production financial logic -was not changed by those fixture updates. - -The pinned x402 Stellar package declares Node >=22, so CI and the documented -minimum now use Node 22. An additional isolated Node 20 smoke run passed the -HTTP/SQLite tests but emitted dependency engine warnings and is not a supported -runtime target. +# Status + +Last updated: 2026-09-21 (contributor addenda 2026-10-16 and 2026-10-17 — +see the first section after this intro).

Ran twice (once building the scripts + interactively, once via the finished `scripts/demo.sh`) with consistent + results. +- **The resolution-commitment design (ADR 0001)** was validated on live + testnet, not just in unit tests: `treasury.agent_create_market` was + called with a `resolution_hash` computed off-chain by + `scripts/spec-hash/`, and `resolver.register_signer_spec` accepted the + matching revealed spec — the hash genuinely round-tripped through real + XDR encoding on a real ledger. +- **The treasury cross-contract auth fix (ADR 0002, `authorize_token_pull`)** + was validated three ways: (1) a unit test using targeted `mock_auths` + (not `mock_all_auths`, which would hide the bug); (2) that same test was + manually re-run with the fix commented out, confirmed to fail with + `HostError: Error(Auth, InvalidAction)` / "Unauthorized function call", + then confirmed to pass again with the fix restored; (3) the real, + unmocked testnet transaction for `agent_create_market` succeeded, which + would have failed with the same auth error had the fix been wrong. +- **All four** `packages/bindings/*` packages: generated, then `npm install + && npm run build` completed with no errors for every one of them + (`market-core`, `reasoning-registry`, `resolver`, `treasury`) — a full + round-trip, not just generation. `resolver`'s and `treasury`'s installs + were slower (each ~4 minutes against this sandbox's npm registry) and so + were run later in the session than the other two, but all four are now + confirmed. + +## What's implemented but not fully round-trip verified + +- **x402's registry-backed `TraceRepository`** + (`x402/registry-trace-repository.ts`): unit-tested with a + dependency-injected fake reader (its real interface, verified against the + actual generated `get_trace` signature). Attempting to run the real + server against the live deployed `reasoning-registry` failed — but the + failure is an environment issue, not a code issue: **Node's own outbound + `fetch` to `soroban-testnet.stellar.org` times out at the TCP level in + this sandbox** (`ETIMEDOUT` / `ENETUNREACH`, reproduced with a bare + `node -e "fetch(...)"` with no OracleDesk code involved at all), while + `curl` to the identical URL and the Rust `stellar` CLI itself both work + fine throughout this same session. This looks like a sandbox network + policy specific to Node's raw socket connections, not a bug here — but it + means the actual RPC round-trip for this path is unverified in this + environment. Whoever runs this outside this sandbox should confirm it + directly. +- **Agents' live mode** (`agents/stellar/adapter.ts` with + `mode: "live"`, i.e. `AGENT_MODE=live` for the CLIs): implemented, + type-checked against the real bindings, and structurally exercised in + dry-run mode end to end. Never run in live mode — that would need the + same Node→testnet RPC path just noted as unverified, plus a funded + agent secret key wired through `AGENT_SECRET_KEY`. +- **`quote_sell`/`collateralOutForShares` against a live contract quote**: + the property test in both `model/fpmm_model.py` and + `agents/core/fpmm.test.ts` verifies the off-chain math against itself + (forward `calc_sell` vs. the `collateralOutForShares` inverse), which is + what the design brief asked for ("add a test against the contract + quote") in spirit — but it was not additionally checked against a live + `market-core.quote_sell` call on testnet with real reserves. + +## Blocked / not attempted + +- **Reflector (SEP-40) price-mode resolution on live testnet**: `resolver`'s + `PriceThreshold` mode is implemented and unit-tested (with a mock + reflector), but no real testnet Reflector contract address was used + anywhere — there was no way to look one up and verify it against + Reflector's own current docs in this session (no browsing tool was + used for this). The demo uses **signer mode** instead, which needs no + external oracle. See `docs/wave-issues/05-reflector-feed-discovery.md`. +- **A real testnet USDC issuer** (e.g. Circle's): not used. `scripts/ + deploy-testnet.sh` deploys a **self-issued** test "USDC" (a real SEP-41 + Stellar Asset Contract, 7 decimals, matching the design doc) rather than + guessing at a real issuer's address. This is called out as a + `TODO(maintainer)` in `scripts/deploy-testnet.sh` and `.env.example`. +- **Actually buying a trace through x402** (payment settlement via a real + facilitator): not attempted. No x402-on-Stellar facilitator URL is known + or hardcoded anywhere in this repo; finding and verifying one needs + browsing x402's current docs, which this session didn't do. `x402/`'s + code path up to "would this trace be served" (hash verification) is + tested; the payment middleware itself is `@x402/*`'s own code, unmodified + here. +- **CI has never actually run** (no GitHub Actions run occurred — this repo + was never pushed). `.github/workflows/ci.yml` mirrors every command this + file claims was run locally, but "the workflow file is correct" is a + weaker claim than "the workflow ran green," and it's flagged as such. + +## Changed from the original design, and why + +- **Treasury's public API**: the design doc describes + `agent_create_market`/`agent_buy`/`agent_sell` calling market-core "as + the trader/creator itself." The *inherited* code had a completely + different, advisory-only `authorize_trade`/`close_trade` pair that never + called market-core at all. This was a real gap (the on-chain caps didn't + cap anything), not a style choice, so it was replaced rather than kept + alongside the new functions — see the commit that did this and ADR + references in `contracts/treasury/src/lib.rs`. +- **Cross-contract calls**: the design doc suggested either + `contractimport!` or a Cargo dependency, "pick the simplest that builds." + A Cargo dependency does not build to wasm (duplicate `__constructor` + export — see ADR 0002), which the design doc didn't anticipate. Switched + to `contractimport!` for both `resolver` and `treasury`. +- **Resolution spec registration is not admin-gated.** The original + resolver had `configure_price`/`configure_signers` as admin-only setters. + Per the resolution-commitment design (ADR 0001), the correct gate is the + cryptographic commitment, not caller identity — anyone can reveal a spec + that hashes correctly, since only whoever picked it in the first place + could have produced a match. +- **Guardian functions added** (`resolver.cancel_proposal`, + `resolver.guardian_void_market`): the design doc's Attested mode + description mentions "a guardian can cancel a proposal or void the market + during the window," but no such functions existed in the inherited code. + Added as thin, admin-gated wrappers. +- **`agents/core` is not a port** of `oracledesk-contracts/agents/*.ts`. + Those files turned out to contain only EVM/Circle/Polymarket *execution* + plumbing (ABI encoding, Circle Developer-Controlled Wallets, EIP-712 + order signing) — exactly what the design brief says to remove, and + nothing chain-agnostic to actually carry over. `agents/core/strategy.ts` + is a fresh, minimal implementation of the two described roles. + +## TODO(maintainer) + +Decisions only a human maintainer should make, left as `TODO(maintainer)` +markers in the files themselves: + +- `SECURITY.md` — an expected triage/response timeline for reports. +- `CODE_OF_CONDUCT.md` — a direct contact channel alongside GitHub's + security-advisory reporting path, if wanted. +- `CONTRIBUTING.md` — an expected PR review turnaround. +- `scripts/deploy-testnet.sh` / `.env.example` — whether to switch the + testnet collateral token from the self-issued test USDC to Circle's real + testnet USDC issuer (needs verifying their current testnet address). +- `.env.example` — the x402-on-Stellar facilitator URL to use for real + payment settlement (none is hardcoded or guessed anywhere in this repo). + +## Known limitations + +- **Testnet only, unaudited.** Nothing here has been professionally + reviewed; do not deploy to mainnet. +- **No indexer.** Soroban RPC's event retention window is short; anything + needing history beyond it has no data source yet (see + `docs/wave-issues/06-event-indexer.md`). +- **Agent-vs-agent liquidity** is unbounded: nothing stops multiple + independent agent deployments from trading against the same + `market-core` markets. The treasury's caps bound one deployment's own + risk, not systemic market behavior. `agents/sim` now quantifies this + (see `docs/simulation.md`, experiment B): with k identical deployments, + capital at risk grows linearly in k while total profit does not. +- **Unredeemed shares expire after the redemption window.** Each market + snapshots a redemption horizon at creation (default 365 days; the admin + default is bounded to 180–1825 days). Once `finalized_at + horizon_secs` + has passed, anyone can call `finalize_market`, which sweeps the market's + **entire** remaining balance — expired user claims, void rounding dust, + any unclaimed LP remainder and accrued fees — to the treasury and closes + redemption (`redeem`/`claim_pool_remainder` then revert with + `RedemptionClosed`). Redeeming before the deadline always pays the exact + `settle_value`; expired claims go to the treasury, not the LP. Markets + created before this `SettleState` bookkeeping (issue #14) have no deadline + and cannot be finalized (`NotSupported`), and stay redeemable through the + old paths. A market waiting on a multi-year deadline can be + TTL-archived before it is finalized and needs a restore (or the keeper, + `docs/wave-issues/14-storage-ttl-keeper.md`) first; the deadline itself is + on-chain state, so a late finalization is still exact. +- **The TWAP ring keeps only the most recent 16 observations.** Each + observation is written per trade timestamp, so 16 distinct-timestamp trades + supersede the creation point: `observe`/`twap` windows that reach further + back than the surviving ring revert with `ObservationTooOld` rather than + returning a value. Windows that extend past the newest observation keep + averaging the last traded price (the accumulator extends + counterfactually), including past `close_time` until a resolver action. + `twap` divides with floor rounding; off-chain mirroring code must floor + identically. Markets created before the accumulator (issue #11) return + `NotSupported` from `observe`/`twap`/`price_cumulative`, and an archived + `Oracle`/`Obs` entry needs a restore like any other entry. +- **Expiry cannot help an oracle the creator controls.** `expire_market` + voids unresolvable markets 30 days after close, but a creator who commits + to a feed they control can still decide the outcome of a *resolvable* + price market; the commitment does not bind oracle identity (ADR 0001, + "Liveness fallback"). +- **Admin keys are rotatable and can be a multisig or the governance + timelock** (ADR 0007, ADR 0008). Every contract now has + `propose_admin`/`accept_admin`/`cancel_admin_transfer` with a seven-day + expiry; `new_admin` may be a classic multisig account, a smart-account + multisig (`CustomAccountInterface::__check_auth`), or the timelock. + `scripts/deploy-testnet.sh` can point the four core contracts at the + timelock from birth (`USE_TIMELOCK=1`), and `scripts/wire-timelock.sh` + migrates an existing deployment through the two-step handover. + - Residual: the deploy still defaults to the deployer EOA as admin + (`USE_TIMELOCK=0`), because the timelock makes the deploy script's own + admin setup calls wait out the delay and CI cannot fast-forward it. + Turning the flag on, or running `wire-timelock.sh`, is the operator's + step. See + `docs/adr/0006-authenticated-wiring-and-deterministic-deploy.md` for the + resolver/treasury wiring handshake. +- **Resolver/treasury wiring is authenticated** (ADR 0006). `market-core` + proposes, the receiving contract proves it is configured for this + market-core, and change events are emitted; the old unauthenticated + `set_resolver`/`set_treasury` are gone. Deploys are deterministic + (`--salt`), and `scripts/migrate-market-core-wiring.sh` upgrades a + pre-handshake deployment. +- **Multi-step flows are atomic through the router** (ADR 0009): + `create_and_reveal_{signers,price}`, `reveal_spec`, and + `buy_and_publish_trace`, so a market cannot exist without its rule and a + trade cannot drop its reasoning trace. +- **Residual admin blast radius.** The treasury's config, price policy and + agent registry are timelocked (loosening waits `config_delay`, tightening + is immediate), which bounds what a compromised admin can unlock for the + *agents*; it does not cover `set_paused`, `set_successor` + + `migrate_market` (which moves positions out of the vault), or any other + contract's admin. Under the deferred timelock default (above) that + exposure is still live on testnet. +- **Treasury vault NAV is conservative, not mark-to-market.** Directional + exposure in open markets counts as zero, so deposits are slightly cheap + and withdrawals slightly expensive while positions are open; positions + opened before a lazy migration from the pre-vault layout, or received by + a successor treasury via `migrate_market`, are not in the open-market + index and count as zero until redeemed. See + `docs/adr/0005-treasury-vault.md` for the residual risks (LP floor moved by + rebalancing trades, fees swept just after a deposit). +- **`treasury`'s per-market cap is cumulative and never decreases** (even + after `close_trade`) — this is the existing, intentional design (a + lifetime cap on capital ever committed to one market), documented in + `contracts/treasury/src/lib.rs`'s comments, but worth stating here since + it's easy to misread as a bug. The separate **net** cap + (`max_net_exposure`, see `docs/architecture.md` "Caps") is what bounds + capital currently deployed; sells and redemptions free it. +- **Price snapshots must be taken within oracle retention.** `snapshot_price` + lets resolution outlive the oracle's bounded history, but only if someone + calls it while the `close_time` record is still retained; there is no + keeper doing so automatically yet. + +## Reproducing this + +```bash +make setup && make build && make lint && make test +make deploy-testnet # idempotent — safe to re-run +make demo # full create -> trade -> resolve -> trace -> verify loop +``` + +See `README.md` for prerequisites. + +## Contributor addendum: interfaces and x402 (#77–#80) + +All six contracts now have deterministic WASM-derived interface manifests, +initial 0.1.0 bindings versions and changelogs. The standalone interface-manifest +tool classifies semantic changes, flags resolver commitment types, and enforces +version/changelog policy against the PR base. Golden tests decode committed +cross-contract WASMs and all six freshly built artifacts. The root CI workflow +now runs the formerly nested checks and the new interface policy. + +x402 multi-network routing and the authorization-only prepare → verify → settle +→ deliver order are covered with a protocol-faithful recording HTTP facilitator. +Tests cover both networks/API keys, stock-SDK 402 compatibility, trace failures +and bounded timeouts, tampered requirements, durable-before-settle failures, +concurrent duplicates, SQLite and memory ledger contracts, free replay and +indeterminate settlement. These replace the earlier statement that payment +ordering depends solely on untested SDK middleware. Real facilitator settlement +and mainnet payment round-trips remain unverified; tests make no real payments. + +The upstream baseline had duplicate treasury error discriminants and stale +fixtures after merges. Newly introduced conflicting errors were moved to unused +44–58, preserving committed 1–33 codes. Treasury fixtures now respect market-core's +100 USDC seed minimum, explicit sell slippage bounds, final settlement before +PnL realization, and per-invocation event lifetimes; production financial logic +was not changed by those fixture updates. + +The pinned x402 Stellar package declares Node >=22, so CI and the documented +minimum now use Node 22.

If the market can still resolve validly it does not void: - a price market whose feed is usable *right now* is resolved (not voided), and a - market with a pending signer proposal is refused with `ResolutionAvailable` - until `finalize_signers` settles it (a proposal always stays finalizable by - anyone). Only a market with nothing resolvable is voided, through - market-core's existing `void_market`; `MarketExpired` records the mode - (`Unrevealed`, `Price` or `Signers`) so indexers can tell it from a guardian void. -* **Terminal state.** `ResolutionState::Expired` is terminal like `Finalized`: - reveals, attestations, `resolve_price` and `guardian_void_market` are refused - afterwards, and the state's TTL is extended whenever it is written. -* **Griefing.** A void pays every holder half per share, so it is never a - free win for one side. Stalling `expire_market` cannot get a correctly - resolvable price market voided, because that call resolves it instead. - Stalling the feed is only possible for a creator who committed to an oracle - they control, a risk that already exists (the commitment does not bind - oracle identity) and is a known limitation to be addressed by the guardian - constraints and multi-oracle follow-up work. A guardian who cancels a - proposal shortly before the deadline can let expiry void a market whose - signers are still re-attesting; that is accepted by design. -* **Unusable feed.** A Reflector call that traps is treated as - `PriceUnavailable`, and the expiry and guardian paths accept - `PriceUnavailable`, `StalePrice` (no acceptable record on the feed's - resolution grid within `max_staleness`, and no earlier one within the - bounded lookback) and `InvalidPrice` (a non-positive published price, or a - feed reporting `resolution() == 0`) as "feed unusable", so a broken or dead - oracle address cannot make expiry revert forever. Any other error (for - example `NotInitialized`) is still surfaced. - -## Weighted-key attestations - -`ResolutionSpec::WeightedKeys` commits to a committee of raw Ed25519 public -keys with weights.

If a fixed signer loses their key or suffers a compromise, an attested market could otherwise freeze or become unresolvable. To address operational rotation needs without breaking the commit-reveal invariant, `ResolutionSpec::Committee(CommitteeRef)` commits to a named committee registry entry rather than raw addresses: - -- `CommitteeRef { committee_id: u64, min_epoch: u32, max_rotation_delta: u32, dispute_window: u64 }` -- Appended as a new `ResolutionSpec` variant so existing `Price` / `Signers` hashes remain byte-identical. -- The committee admin proposes rotations subject to a time lock (`rotation_delay >= MIN_ROTATION_DELAY = 86_400`). Anyone can execute the rotation once the delay elapses. -- `attest` and `finalize_signers` enforce rotation bounds: `epoch >= min_epoch` and `epoch - min_epoch <= max_rotation_delta`. A creator setting `max_rotation_delta = 0` gets exact fixed-membership semantics. -- In `finalize_signers`, votes are recounted against the current epoch's active members (`MemberAt(committee_id, epoch)`), preventing rotated-out keys from deciding outcomes. - -## Hybrid resolution mode: Price feed with attested fallback - -High-frequency Reflector oracle feeds can experience unexpected upstream outages, sequencer downtime, or missing asset feeds. `ResolutionSpec::Hybrid(HybridConfig)` couples a primary price threshold check with a time-locked signer fallback: - -- Commit structure: `HybridConfig { price: PriceConfig, fallback_signers: Vec
, fallback_threshold: u32, dispute_window: u64, fallback_delay: u64 }`. -- Prior to `close_time + fallback_delay`, the resolver strictly requires `resolve_price`. -- After `close_time + fallback_delay`, anyone can call `open_fallback(market_id)` to transition `ResolutionState::HybridPricePending` to `ResolutionState::HybridFallbackOpen`, enabling signers to attest. -- Dual-path safety: if a usable price report arrives while an attested proposal is still pending in its dispute window, `resolve_price` immediately supersedes the proposal and finalizes the market directly from the oracle feed. - -## Reasoning evidence commitments - -To guarantee verifiable accountability for off-chain agent attestations, the resolver links attestation votes to cryptographic evidence traces published in `reasoning-registry`: - -- `set_evidence_config(min_policy, registry)` configures system-wide trace verification standards. -- `attest_with_evidence(market_id, outcome, signer, trace_hash, reasoning_hash)` verifies with `reasoning-registry` that the trace exists and satisfies the required `EvidencePolicy`. -- Replay prevention: each `trace_hash` can be cited only once per market. -- Observability: the resolver retains an immutable append-only evidence trail accessible via `evidence_count` and `evidence_at`. - -## Constrained guardian powers and audit trail - -To eliminate unbounded administrative discretion and guarantee credible decentralization: - -- Time-window constraints: - - `cancel_proposal` is permitted only during the active dispute window (`DisputeWindowClosed` returned otherwise). - - `guardian_void_market` can only be invoked after grace periods have expired: `close_time + REVEAL_GRACE_SECS` (3 days) for unrevealed specs, `close_time + ORACLE_GRACE_SECS` (1 day) for failing price feeds, and `close_time + SIGNER_GRACE_SECS` (7 days) for unresponsive signer sets. -- Cancellation rate limiting: `cancel_proposal` is strictly capped at `MAX_CANCELS_PER_MARKET = 2` cancellations per market to prevent indefinite griefing. -- Audit trail: both `cancel_proposal` and `guardian_void_market` require a typed `GuardianReason` enum (`StaleOracleFeed = 1`, `CompromisedSigner = 2`, `AmbiguousSpec = 3`, `LivenessFailure = 4`, `Other = 5`), emitting structured `GuardianAction` events with execution metadata. - -## Agent flow and recovery - -Create and reveal are two transactions, and between them only the agent -holds the preimage of `resolution_hash`. If the spec is lost there (crash, -wiped working directory, container restart), the market can only end -through `guardian_void_market`. The market-maker -(`agents/bin/market-maker.ts`, `agents/core/maker-flow.ts`) therefore runs: - -1. **Build** a `SpecJson` (`agents/core/spec.ts`) from `MM_*` config: - signers mode (`MM_SIGNERS`, default `deployments.agent`; - `MM_SIGNER_THRESHOLD`; `MM_DISPUTE_WINDOW_SECS`) or price mode - (`MM_REFLECTOR`, `MM_ASSET`, `MM_PRICE_THRESHOLD`, `MM_PRICE_DIRECTION`, - `MM_MAX_STALENESS_SECS`, or a signal's own `priceRule`). `validateSpec` - mirrors the resolver's `InvalidConfig` rules exactly, and `close_time` - must exceed `now + dispute_window + MM_CLOSE_MARGIN_SECS`. -2. **Canonicalize**: signers are sorted lexicographically by strkey. `Vec` - order is part of the XDR (`signer_spec_hash_depends_on_signer_order`), so - the same order is used to hash and to reveal. `scripts/seed-market.sh` - sorts the same way. -3. **Commit** through `SpecHasher` (`agents/core/spec-hasher.ts`): - `scripts/spec-hash` via `execFile` (`SPEC_HASH_BIN` for a prebuilt binary, - else `cargo run`), or the TypeScript resolution-spec library when - installed. `--verify-spec-hash` runs both and fails on disagreement. -4. **Persist** a `pending_create` entry to `AGENT_SPEC_DIR` (default - `./.specs`, gitignored, separate from `.traces/`) with - `agents/core/spec-store.ts`: temp file, fsync, atomic rename, fsync of - the directory, then the optional `SPEC_BACKUP_CMD`. The create is not - built until this write has resolved. **Back up this directory.** -5. **Create** with `resolution_hash = commitment`, mark the entry `created` - with its market id, **reveal** with `register_signer_spec` / - `register_price_spec`, and mark it `revealed`. - -`recoverSpecs` runs at startup and after every create attempt, and drives -every non-terminal entry forward: - -- `created`: if the market's spec is not registered yet, reveal it. A price - reveal leaves `state()` at `Unconfigured`, so the resolver's - `Price(market_id)` entry is checked too. Reveal is permissionless, so - `MarketAlreadyConfigured` from someone who revealed first counts as - success once the market's `resolution_hash` is confirmed to equal the - stored commitment. A failed reveal stays `created` and is retried; entries - older than `MM_STALE_REVEAL_SECS` are logged as alerts. -- `pending_create` (crash or RPC failure after the write, market id unknown): - scan the newest `MM_RECOVERY_MAX_SCAN` market ids for - `resolution_hash == commitment && creator == treasury`, plus a matching - `question_hash` and `close_time`. Each market is claimed by at most one - entry, because identical specs (the spec does not include the question) - share a commitment. A match moves to `created` and is revealed. With no - match after `MM_PENDING_TTL_SECS`, the entry is marked `abandoned` and its - file is kept. -- A create that failed before submission (simulation rejected it, e.g. - `TradeCapExceeded`; the adapter raises `NotSubmittedError`) created no - market, so its entry is marked `abandoned` immediately instead of waiting - for the TTL. - -Dry-run mode uses an in-memory store and skips recovery, so it never -leaves entries behind for a live run. Creating and revealing atomically in -one transaction (`agent_create_market_and_reveal`, used by -`scripts/seed-market.sh`) removes this window entirely; this flow and its -recovery loop cover agents that still use the two-step path. +# ADR 0001: Resolution commitment on `create_market` + +## Status + +Accepted. + +## Context + +The original `market-core` design let a market's creator wire up a resolution +rule (a Reflector price threshold, or an m-of-n signer set) *after* the market +was already open and trading.

Registration additionally + calls `resolution()` on the committed reflector and rejects ( + `InvalidConfig`) a `window / resolution` above the sample cap or a + `min_samples` above the slot count, so an unresolvable market is caught + at reveal, not at close. +* **Rejection rules.** Fewer than `min_samples` present samples, a gap + above `max_gap` between `start` and the first sample, between any two + consecutive samples, or between the last sample and `close_time`, all + fail `StalePrice`; a sample price `<= 0` or any arithmetic overflow + fails `InvalidPrice`. Failed resolution leaves the market untouched, and + `expire_market` treats those errors as "feed unusable" exactly as for + the other price shapes. +* **Weighting formula.** Each sample is weighted by the time until the + next sample; the newest sample is weighted `close_time - last_ts + 1` + (the closing second is included — the convention the issue offered as + "`close_time - ts_last + 1` or `resolution()`", this ADR picks the + former and both the numerator and denominator apply it consistently). + `twap = floor( Σ price_i * dt_i / Σ dt_i )` in `i128` with + `checked_mul`/`checked_add`/`checked_div`; the committed + `AtOrAbove`/`AtOrBelow` comparison applies to the floored average. + Threshold units are feed-native, like the legacy `Price` variant (the + decimal-explicit question is #26's and stays with `ScaledPriceConfig`). +* **Sample cap and budget.** `MAX_TWAP_SAMPLES = 32` bounds the + cross-contract `price` reads per resolution attempt — as a cap on + *reads inspected*, not samples found, so a window full of missing + records terminates instead of walking the grid forever. The issue asks + for a value "chosen from measured CPU cost" (`env.cost_estimate()` + against the registered wasm, recorded here). **That measurement is not + available and this number is reasoned, not measured**: the in-tree + build gate (the wasm-hash verification build script and + `oracledesk-types`) fails at the current tip, so no test executes; no + benchmark figure is claimed. 32 is instead derived from the contract's + own accepted ceilings — `MAX_WEIGHTED_SIGNERS = 32` / + `MAX_COMMITTEE = 32`, and the weighted-keys path verifies up to 32 + ed25519 signatures in one call at a documented 23.1M instructions (see + "Weighted-key attestations"), a per-item cost strictly above one bounded + price read — so a 32-sample TWAP cannot exceed a flow the protocol + already ships against. A measured re-derivation is a maintainer + follow-up alongside the golden re-pin. +* **Manipulation scope.** A TWAP dilutes a single print, but a sustained + push still moves the average; median filtering is out of scope. + +## Liveness fallback + +A market whose spec is never revealed, whose committed feed is permanently +unusable, or whose signers go silent would otherwise lock its collateral until +the single guardian key acts. `Resolver::expire_market` removes that dependency. + +* **Deadline.** `close_time + RESOLUTION_GRACE_SECS` (30 days, a compile-time + constant so no admin can shorten it). It reads only market-core's + `close_time`, so it applies to unrevealed specs and to every market created + before this change, with no spec migration. `resolution_deadline(market_id)` + exposes it. +* **Permissionless, liveness-first.** After the deadline anyone may call + `expire_market`. If the market can still resolve validly it does not void: + a price market whose feed is usable *right now* is resolved (not voided), and a + market with a pending signer proposal is refused with `ResolutionAvailable` + until `finalize_signers` settles it (a proposal always stays finalizable by + anyone). Only a market with nothing resolvable is voided, through + market-core's existing `void_market`; `MarketExpired` records the mode + (`Unrevealed`, `Price` or `Signers`) so indexers can tell it from a guardian void. +* **Terminal state.** `ResolutionState::Expired` is terminal like `Finalized`: + reveals, attestations, `resolve_price` and `guardian_void_market` are refused + afterwards, and the state's TTL is extended whenever it is written. +* **Griefing.** A void pays every holder half per share, so it is never a + free win for one side. Stalling `expire_market` cannot get a correctly + resolvable price market voided, because that call resolves it instead. + Stalling the feed is only possible for a creator who committed to an oracle + they control, a risk that already exists (the commitment does not bind + oracle identity) and is a known limitation to be addressed by the guardian + constraints and multi-oracle follow-up work. A guardian who cancels a + proposal shortly before the deadline can let expiry void a market whose + signers are still re-attesting; that is accepted by design. +* **Unusable feed.** A Reflector call that traps is treated as + `PriceUnavailable`, and the expiry and guardian paths accept + `PriceUnavailable`, `StalePrice` (no acceptable record on the feed's + resolution grid within `max_staleness`, and no earlier one within the + bounded lookback) and `InvalidPrice` (a non-positive published price, or a + feed reporting `resolution() == 0`) as "feed unusable", so a broken or dead + oracle address cannot make expiry revert forever. Any other error (for + example `NotInitialized`) is still surfaced. + +## Weighted-key attestations + +`ResolutionSpec::WeightedKeys` commits to a committee of raw Ed25519 public +keys with weights.

If a fixed signer loses their key or suffers a compromise, an attested market could otherwise freeze or become unresolvable. To address operational rotation needs without breaking the commit-reveal invariant, `ResolutionSpec::Committee(CommitteeRef)` commits to a named committee registry entry rather than raw addresses: + +- `CommitteeRef { committee_id: u64, min_epoch: u32, max_rotation_delta: u32, dispute_window: u64 }` +- Appended as a new `ResolutionSpec` variant so existing `Price` / `Signers` hashes remain byte-identical. +- The committee admin proposes rotations subject to a time lock (`rotation_delay >= MIN_ROTATION_DELAY = 86_400`). Anyone can execute the rotation once the delay elapses. +- `attest` and `finalize_signers` enforce rotation bounds: `epoch >= min_epoch` and `epoch - min_epoch <= max_rotation_delta`. A creator setting `max_rotation_delta = 0` gets exact fixed-membership semantics. +- In `finalize_signers`, votes are recounted against the current epoch's active members (`MemberAt(committee_id, epoch)`), preventing rotated-out keys from deciding outcomes. + +## Hybrid resolution mode: Price feed with attested fallback + +High-frequency Reflector oracle feeds can experience unexpected upstream outages, sequencer downtime, or missing asset feeds. `ResolutionSpec::Hybrid(HybridConfig)` couples a primary price threshold check with a time-locked signer fallback: + +- Commit structure: `HybridConfig { price: PriceConfig, fallback_signers: Vec
, fallback_threshold: u32, dispute_window: u64, fallback_delay: u64 }`. +- Prior to `close_time + fallback_delay`, the resolver strictly requires `resolve_price`. +- After `close_time + fallback_delay`, anyone can call `open_fallback(market_id)` to transition `ResolutionState::HybridPricePending` to `ResolutionState::HybridFallbackOpen`, enabling signers to attest. +- Dual-path safety: if a usable price report arrives while an attested proposal is still pending in its dispute window, `resolve_price` immediately supersedes the proposal and finalizes the market directly from the oracle feed. + +## Reasoning evidence commitments + +To guarantee verifiable accountability for off-chain agent attestations, the resolver links attestation votes to cryptographic evidence traces published in `reasoning-registry`: + +- `set_evidence_config(min_policy, registry)` configures system-wide trace verification standards. +- `attest_with_evidence(market_id, outcome, signer, trace_hash, reasoning_hash)` verifies with `reasoning-registry` that the trace exists and satisfies the required `EvidencePolicy`. +- Replay prevention: each `trace_hash` can be cited only once per market. +- Observability: the resolver retains an immutable append-only evidence trail accessible via `evidence_count` and `evidence_at`. + +## Constrained guardian powers and audit trail + +To eliminate unbounded administrative discretion and guarantee credible decentralization: + +- Time-window constraints: + - `cancel_proposal` is permitted only during the active dispute window (`DisputeWindowClosed` returned otherwise). + - `guardian_void_market` can only be invoked after grace periods have expired: `close_time + REVEAL_GRACE_SECS` (3 days) for unrevealed specs, `close_time + ORACLE_GRACE_SECS` (1 day) for failing price feeds, and `close_time + SIGNER_GRACE_SECS` (7 days) for unresponsive signer sets. +- Cancellation rate limiting: `cancel_proposal` is strictly capped at `MAX_CANCELS_PER_MARKET = 2` cancellations per market to prevent indefinite griefing. +- Audit trail: both `cancel_proposal` and `guardian_void_market` require a typed `GuardianReason` enum (`StaleOracleFeed = 1`, `CompromisedSigner = 2`, `AmbiguousSpec = 3`, `LivenessFailure = 4`, `Other = 5`), emitting structured `GuardianAction` events with execution metadata. + +## Agent flow and recovery + +Create and reveal are two transactions, and between them only the agent +holds the preimage of `resolution_hash`.

Only the admin could +move funds out, through `withdraw(to, amount)`. A deposit from anyone other +than the operator was a donation to the admin key, so outside funders could +not back an agent and share in its results. + +Turning the treasury into a vault needs a net asset value (NAV) to price +shares. The treasury holds positions across many markets, and the obvious +valuation, the FPMM spot price, can be moved by anyone who trades. If NAV +followed spot, a depositor could push prices up, withdraw at the inflated +NAV, and leave the loss with everyone else. Vaults also have a well-known +first-depositor attack: deposit 1 unit, donate a large amount straight to the +contract, and round the next depositor's shares down to almost nothing. + +## Decision + +### Valuation: settled-plus-floor + +``` +nav = idle + + Σ over the open-market index of + open market: min(pos.yes, pos.no) complete sets + + min(reserve_yes, reserve_no) if LP role unclaimed LP + final market: settle_value(position) + settle_value(LP reserves) + - queue_reserved +``` + +- `idle` is the treasury's collateral balance. +- Complete sets redeem 1:1 whatever the outcome, so `min(yes, no)` is value + the treasury gets back for certain. +- For an LP role that has not been claimed, `min(reserve_yes, reserve_no)` is + the least the pool remainder can pay out. +- A final market counts exactly what market-core's `settle_value` pays + (`Yes → yes`, `No → no`, `Void → (yes + no) / 2`). +- `queue_reserved` is collateral already owed to burned shares (see + "Withdrawals"). Subtracting it stops that collateral being counted twice. + +The directional part of a position (`|yes - no|`) is valued at **zero**. Spot +and TWAP valuations were rejected: spot can be manipulated within a single +transaction, and no TWAP exists yet. + +**Trade-off, worked example.** The treasury holds 1,000 USDC idle and 150 YES +/ 40 NO shares in an open market where YES trades at 70%. Mark-to-market +would value the position at about 150 × 0.7 + 40 × 0.3 = 117. The floor is +`min(150, 40) = 40`, so NAV is 1,040, not 1,117. While the position is open, +a new depositor's shares are slightly cheap and a withdrawing shareholder's +are slightly expensive. Once the market resolves YES, the position is worth +exactly 150, NAV rises to 1,150, and every shareholder gains pro rata. The +bias always favours the shareholders who stay in the vault over those +entering or leaving. Under-valuation is the price of a NAV that third-party +trades cannot push up. + +### Open-market index + +NAV needs the list of markets where the treasury holds capital, and nothing +on-chain gave that list. The treasury keeps an index: +`OpenMarketAt(0..count) -> { core, market_id }` plus a reverse +`OpenMarketSlot(core, id)` for swap-and-pop removal. + +- A market joins the index on its first buy or creation. +- It leaves once the treasury holds nothing in it: no shares and no unclaimed + LP role. This is checked after `redeem`, `claim_pool_remainder` and their + `legacy_*` variants. `migrate_market` also removes it. +- Each entry records its market-core, so positions left in a market-core the + treasury has since switched away from (see "Timelocked configuration" in + `docs/architecture.md`) keep counting. + +The index is capped at `MAX_OPEN_MARKETS = 12`. A buy or creation in a 13th +market fails with `TooManyOpenMarkets`. Each entry costs two cross-contract +reads, and each read instantiates market-core at about 2.5 MB of memory. +Measured with the test host's per-invocation limit checks: + +| Open markets | Call | Memory | Limit | +| ---: | --- | ---: | ---: | +| 32 | `nav()` alone | ~81 MB | 40 MiB | +| 16 | `deposit` | ~40.4 MB | 40 MiB | +| 12 | `deposit` / `request_withdraw` | ~30.3 MB, ~15M instructions | 40 MiB | + +The 12-market case is pinned by `nav_budget_within_limits_at_max_open_markets`. + +### Shares + +Shares are internal balances (`Shares(owner)`, `TotalShares`), not a SEP-41 +token. A transferable share token can wrap them later. Keeping them internal +avoids a second contract, a cross-contract call per transfer, and the +question of what a share transfer means for the withdrawal queue while the +economics are still settling. + +``` +shares_for_deposit(amount) = amount × (supply + 1_000) / (nav + 1) floor +assets_for_shares(shares) = shares × (nav + 1) / (supply + 1_000) floor +``` + +Both directions round down, in favour of the vault. A deposit followed +immediately by a withdrawal never returns more than was put in. This is +checked by a randomized property test (1,000 cases) and end to end. + +**Inflation protection.** The virtual offset (1,000 virtual shares, 1 +virtual stroop; the ERC-4626 mitigation) is what defeats the donation +attack. The attacker's donation is shared with the virtual shares, so +inflating the price enough to round a victim's deposit to zero costs the +attacker about 1,000 times what it takes from the victim.

The commitment is + computed from `spec_v2` **locally** (mirroring the resolver's own hashing) + and passed to `market-core.create_market`, so the commitment and the reveal + are consistent by construction; a mismatch is impossible rather than merely + checked. Emits `MarketCreatedAndRevealed`. +- `reveal_spec(market_id, spec_v2)` — the deferred reveal for a market created + by the commit-now/reveal-later path, validating the rule before + `resolver.register_spec_v2`. +- `buy_and_publish_trace(trader, market_id, outcome, collateral_in, + min_shares_out, action, trace_hash, ipfs_cid)` — buys through market-core + and publishes the trace through the registry in one transaction, so the + trace cannot be skipped after the trade. Emits `BoughtAndPublishedTrace`. + Rejects empty `action`/`ipfs_cid` with `InvalidTrace`. + +### Authorization + +Each entrypoint calls `creator.require_auth()` / `trader.require_auth()` at the +**root** of the call tree. market-core and the registry call `require_auth` +for the same address deeper down; a non-root `require_auth` fails unless the +address is already anchored, so the router anchors it first. A caller still +authorizes exactly one account — the router adds no authority of its own. + +`reasoning_registry` is optional: if it is `None`, `buy_and_publish_trace` +returns `NotInitialized`. + +## Consequences + +- The create+reveal and buy+trace flows are all-or-nothing; there is no window + in which a market exists without its rule or a trade exists without its + trace. +- Clients point at one router address and never choose a resolver or registry + themselves, so they cannot be tricked into a different one. +- The router holds no funds, no roles and no admin, so it is not a target for + a governance action and needs no timelock. diff --git a/oracledesk-stellar/docs/agent-readiness.md b/oracledesk-stellar/docs/agent-readiness.md index 45568387..e12090d0 100644 --- a/oracledesk-stellar/docs/agent-readiness.md +++ b/oracledesk-stellar/docs/agent-readiness.md @@ -1,31 +1,31 @@ -# Agent safety and readiness limits - -The trader task now requires an injected due-diligence verifier and rejects -trades when one is not configured.

Each outcome has its own counter and signers are deduplicated - per `(outcome, signer)`; the first outcome to reach threshold is - proposed and later `Yes`/`No` quorums never move it, except that an - `Invalid` quorum replaces a pending `Yes`/`No` proposal and restarts the - dispute window. `attest` requires `close_time` to have passed, which is - what keeps a committee void (market-core's `void_market` has no close-time - guard) from happening early. Proposals and finalizations emit - `ResolutionProposedV2` / `ResolutionFinalizedV2` (carrying - `AttestedOutcome`); the old `Outcome`-typed events are no longer - emitted.

Look the current values -up from Reflector's documentation or the feed contract itself; do not -assume them. A price market nobody resolves before its `close_time` record -ages out would otherwise return `PriceUnavailable` forever and could only be -voided. - -`snapshot_price(market_id, caller)` closes that gap. Anyone may call it -after `close_time` while the market is unresolved; it reads the committed -feed exactly as resolution does (on the `resolution()` grid, at or before -`close_time`), validates it with the same rule -(`validate_price`: not after close, price strictly positive, no older than -`max_staleness`), and -stores it as a `PriceSnapshot`. An invalid read is never stored, and the -first valid snapshot wins (`SnapshotExists`): the answer for a fixed -`(asset, close_time)` is deterministic, so this deliberately prefers -determinism over an oracle later rewriting history. Every price path -(`resolve_price`, `expire_market`, `open_fallback`, and the guardian's -`OracleUnavailable` check) uses a stored snapshot before the live feed and -then skips the oracle call. `PriceResolutionV2` adds `from_snapshot`; the -original `PriceResolution` is still emitted alongside it for one release. - -Operators and agents should call `snapshot_price` within one oracle period -of `close_time` (CLI: `stellar contract invoke --id $RESOLVER -- snapshot_price ---market_id --caller

Upholding the proposal resolves to it and -forfeits the bond to market-core's treasury; any other ruling resolves to the -verdict (or voids for `Invalid`) and returns the bond. If nobody rules within -`escalation_timeout` of the dispute, anyone may `expire_dispute`: the market is -voided and the bond refunded. `guardian_void_market` during a dispute also -refunds it. Bonds leave escrow only via the permissionless -`claim_dispute_bond` (pull, so a payee that cannot receive cannot block -settlement); the resolver's token balance always equals the bonds it still -holds. - -```mermaid -stateDiagram-v2 - [*] --> SignersPending: register_disputable_spec - SignersPending --> SignersPending: attest (proposal at threshold) - SignersPending --> Finalized: finalize_signers (window elapsed) - SignersPending --> Disputed: dispute (window open, bond escrowed) - Disputed --> Finalized: settle_dispute / escalation_attest (k votes) - Disputed --> Finalized: expire_dispute (timeout, void, refund) - Disputed --> Finalized: guardian_void_market (void, refund) - SignersPending --> Expired: expire_market (no pending proposal) - Finalized --> [*]: claim_dispute_bond pays the payee -``` - -**Rewards, honestly:** a winning disputer only gets their bond back.

This means the caps are a real on-chain limit on what the -automated agent can deploy — an agent's own key calling `market-core` -directly would just be trading its own separate funds, not bypassing a cap -on the treasury's money. The `*_v2` twins forward the same caps plus -market-core's deadline / limit-price bounds, so a revert from either layer -leaves the caps unchanged (the whole invocation is atomic). - -Treasury `agent_split` / `agent_merge` forwarders are **not** implemented -yet (a non-goal of the split/merge change); agents that need the primitives -call `market-core` directly today. They can be added later as thin wrappers -that reuse the existing caps. - -**Agents.** The treasury keeps a registry of up to `MAX_AGENTS = 16` agents, -each with an `AgentPolicy { roles, max_trade, max_daily, active }`. Roles are -a bitmask: `ROLE_CREATE` (`agent_create_market`), `ROLE_TRADE` (`agent_buy`, -`agent_sell` and their `_v2` twins) and `ROLE_SETTLE` (`redeem`, -`claim_pool_remainder`, `close_trade`, `agent_claim_lp_fees`, the `legacy_*` -recovery calls). The constructor registers its `agent` with every role and -the global caps; `scripts/deploy-testnet.sh` then proposes a separate maker -(`CREATE | SETTLE`) and trader (`TRADE | SETTLE`), so a leaked trader key -cannot create markets and a runaway trader cannot spend the maker's budget. -An agent's `max_trade` and `max_daily` sit under the global caps; both levels -are checked on every spend, and each agent has its own sliding daily window -(`agent_daily_usage`). `TradeAuthorized.agent` names the acting agent. -Positions are still pooled: market-core only ever sees the treasury, so the -per-agent state is usage, not ownership. `remove_agent` deactivates at once -(usage history kept), but at least one active `ROLE_SETTLE` agent must always -remain so open positions can be settled. Narrowing an active agent's policy -applies at once; adding, reactivating or widening one goes through the -timelock below (`set_agent` → `execute_agent` after `config_delay`). -`get_config()` survives as a deprecated view in the old `RiskConfig` shape, -whose `agent` is the first registered agent; a stored pre-registry config is -migrated lazily into `GlobalConfig` plus one full-role agent. - -**Caps.** Four limits apply to every buy and market creation: - -- `max_trade`: per call. -- `max_market`: lifetime capital ever committed to one market. Never freed, - not by sells, redemptions or `close_trade`. -- `max_daily`: a **sliding** 24h limit. Usage is kept in 25 hourly buckets - (`UsageWindow`, instance storage); a trade at hour `h` is accepted only if - buckets `h-24 ..= h` plus the trade stay within `max_daily`. Every real - 24h interval falls inside those 25 hours, so no trailing 24h ever exceeds - the cap. The rounding is conservative: a trade keeps counting for 24-25h. - (The previous fixed window reset lazily, so `max_daily` could be spent - just before a reset and again just after it.) `daily_usage()` keeps its - `DailyUsage` shape (`day_start` is now the start of the oldest counted - hour) and is side-effect free; `daily_usage_detail()` returns the buckets - and `daily_headroom()` the remaining allowance. -- `max_net_exposure`: capital *currently* deployed across all markets. The - treasury records collateral in (buys, creations) and out (sells, - redemptions, pool remainders, LP fee claims) per market (`NetPosition`) - and keeps a running `net_exposure() = sum(max(0, in - out))`. Profit in - one market floors at zero and never offsets another. A sell frees net - headroom but not lifetime headroom; `close_trade` changes neither; - `migrate_market` drops the market from net accounting. Enforcement uses - only these local counters (no extra cross-contract call on the hot path) - and never a pool price: a spot-valued cap would let anyone pump a price to - unlock headroom or crash it to block the agent. `market_valuation(id)` - reports `cost_basis`, a manipulation-resistant `floor_value` (complete - sets `min(yes, no)` plus `min(reserve_yes, reserve_no)` as unclaimed LP; - the settlement value once final), an informational `spot_value`, and - `at_risk = max(0, cost_basis - floor_value)`. Net accounting starts when - the contract is deployed (missing entries read as zero). The treasury's -creator-side claims are split the same way the fees are: `collect_market_fees` -sweeps the **protocol portion** to the treasury, while `agent_claim_lp_fees` -claims the LP portion for markets the treasury created. - -**Price limits.** Size caps do not stop the treasury buying YES at 99% in a -pool that was at 40% a moment ago (a buggy strategy, a compromised agent key, -a sandwich). A `PricePolicy { max_buy_price_bps, min_sell_price_bps, -max_impact_bps, max_slippage_bps }` (defaults 9500 / 500 / 500 / 200) is -enforced inside every agent trade, using market-core's own `get_price` so the -rounding matches what clients see: - -- buys need the outcome's spot price `<= max_buy_price_bps`, sells need it - `>= min_sell_price_bps`; `agent_create_market` needs `initial_yes_bps` - within `[min_sell, max_buy]`; -- `min_shares_out` is raised to the same-transaction `quote_buy` minus - `max_slippage_bps` (never below 1), and `max_shares_in` is capped at - `quote_sell` plus `max_slippage_bps` (rounded up); -- after the trade, `|p_after - p_before| <= max_impact_bps`. - -Because the quote runs against the same pool state as the trade, the quote -floor only protects the agent's own intent; the band is what stops a -front-runner (pushing the price out of band fails the trade), and the impact -limit bounds how far any single trade moves the pool. Large trades in thin -pools are rejected by the impact limit, so strategies must split them; -`max_trade` and `max_impact_bps` interact. market-core's `SlippageExceeded` -is remapped to the treasury's own `SlippageExceeded = 27`; other market-core -errors are re-raised with market-core's codes, which overlap the treasury's -numerically. The checks add three cross-contract view calls per trade: a -1 USDC `agent_buy` against a real market-core measured ~3.5M instructions in -`price_checks_cost_estimate_recorded`. - -**Timelocked configuration.** The global caps (`GlobalConfig`: collateral, -market_core, `max_trade`, `max_market`, `max_daily`, `max_net_exposure`), the -price policy and agent policies change through propose/execute with -asymmetric rules: anything that only tightens (lower caps, a narrower band, -fewer roles) applies immediately; anything that loosens (any raised cap, a -new or widened agent, a changed collateral or market-core) waits -`config_delay` (at least one day, set at construction, can only grow via -`set_config_delay`) and is announced first by `ConfigProposed` / -`AgentPolicyProposed` / `PricePolicyProposed`. A proposal that lowers one -value and raises another is a loosening as a whole; split it to apply the -tightening at once. Execution (`execute_config`, `execute_agent`, -`execute_price_policy`) is permissionless once due, so it never depends on the -admin; `cancel_*` is admin-only. A tightening applied while a loosening is -pending leaves that proposal and its timer as they are. A collateral switch -is only allowed for an empty treasury (no balance, open markets or queued -withdrawals). A market-core switch leaves positions in the old core where they -are: the old core is recorded as legacy, `legacy_redeem` / -`legacy_claim_pool_remainder` recover them, and exposure for any later core -is kept under keys namespaced by core address (the original core keeps the -old `Market(id)` / `Net(id)` keys) so restarted market ids cannot collide. -The new core still needs its own `propose_treasury` handshake for fee sweeps. -This bounds -what a compromised admin can unlock *for the agents*; it is not a custody -control (see "Vault" and SECURITY.md). - -**Vault.** Deposits mint internal shares against a conservative NAV and -withdrawals burn them; there is no admin `withdraw`. `nav() = idle + -Σ floor(open markets) - queue_reserved`, where an open market's floor is its -complete sets `min(yes, no)` plus `min(reserve_yes, reserve_no)` for an -unclaimed LP role, and a final market counts its exact settlement value. The -directional part of a position is valued at zero, so trading against a pool -cannot raise NAV. The open-market index walked by `nav()` is bounded at -`MAX_OPEN_MARKETS = 12` (two market-core reads each; 16 already used ~40 MB -of the 40 MiB per-transaction memory limit); a buy or creation in a 13th -market fails with `TooManyOpenMarkets`, and markets leave the index once -redeemed and claimed. Share math rounds toward the vault and uses a virtual -offset (1,000 shares / 1 stroop) plus dead shares on the first mint against -donation-based share inflation; deposits must be at least `MIN_DEPOSIT` -(10 USDC). `request_withdraw` prices the shares at once, pays what free idle -collateral allows and queues the remainder as a FIFO ticket; -`claim_withdraw(ticket)` (permissionless, pays the owner) settles the head -ticket as capital returns, and agents can never spend `queue_reserved()`. -While paused, `emergency_withdraw` pays shareholders their pro-rata part of -free idle collateral without touching market-core. See -[ADR 0005](adr/0005-treasury-vault.md). - -**Migration to a successor treasury.** The treasury has no upgrade path, so -redeploying it (a bug fix, or anything the timelocked setters above do not -cover) means deploying a new contract. `set_successor(successor)` -(admin) records where value may go and emits `SuccessorSet`; then -`migrate_market(market_id)` (admin, **not** agent) moves the treasury's -YES/NO position and, if it is still the LP, its LP ownership for one market -to the successor — market by market, so the footprint stays bounded — and -emits `MarketMigrated`. The auth model: - -- The agent has no path: both migration entrypoints are `require_admin`. -- The destination is fixed to the configured `Successor` — `migrate_market` - takes no destination argument, so even a compromised agent key cannot - redirect value. It is still an admin power over shareholders' capital: - migrated positions leave this treasury's NAV without compensation, so a - compromised admin could move them to a successor it controls. The - successor is visible on-chain via `SuccessorSet` before any - `migrate_market`, and SECURITY.md lists this as a known admin power. -- The treasury's calls to market-core's `transfer_position` / `transfer_lp` - are *direct* calls, so market-core's `require_auth` on the treasury's own - address is satisfied implicitly by the invoker rule — no - `authorize_as_current_contract` entry is needed (unlike the nested token - call in `authorize_token_pull`). This is proven by the - `pitfall_migrate_market_needs_only_admin_auth` test, which permits only - the admin's signature and no sub-invocations. - -A migrated market's `MarketExposure` on the successor starts at zero and the -old treasury's entry is closed (`open = false`, amount preserved), so the -successor's caps apply to its own future activity — acceptable because the -cap is a per-deployment risk bound, not a market-level accounting value. -Successor-side acceptance (`accept_migration`) is deliberately not -implemented: it would record provenance only, and the events plus the -successor's own exposure records are enough for an off-chain dashboard -([wave-issue 08](wave-issues/08-treasury-exposure-dashboard.md)). - -- `buy` locks `collateral_in = net + fee`, because `net` mints sets and - `fee` accrues to the protocol/LP shares. The fee remains inside - `locked` until `sweep_fees` / `claim_lp_fees` / `claim_pool_remainder` - subtract it — it is never double-counted. -- `sell` burns gross sets and pays out `collateral_out`; the fee - `gross - out` stays in the market's fee accrual, and the locked delta is - only the cash actually leaving. -- `claim_pool_remainder` zeroes the reserves and subtracts the payout - from `locked`. After this claim, `sets_minted`+`$fees_accrued` is no - longer the correct figure for what the market still owes; the - solvency report uses `locked` alone in that state. -- `sweep_fees` subtracts the swept amount from `locked`. -- Any negative result returns `Error::Overflow` (with a `debug_assert` - in debug builds). - -**Permissionless settlement & exposure release (#45).** Settle market capital -without depending on hot agent keys: `settle_market(caller, market_id)` is -permissionless and idempotent. It redeems the treasury's outcome-share position if -any, claims the LP remainder if the treasury created the market, marks market exposure -closed (`open = false`), and records realized proceeds under `Realized(market_id)`. -Calls to `market-core` use generated `try_` client methods so expected core errors -(`NothingToRedeem`, `AlreadyClaimed`, `NotFinal`) map cleanly to 0 or distinct treasury -errors without unhandled transaction aborts. Settlement operates even when the treasury -is paused (stopping trading, not fund recovery). - -**Realized PnL & auto-pause on drawdown (#46).** Cumulative losses across markets -are bounded by an automated drawdown guard. The treasury tracks collateral cost -(buys and market seeds) and proceeds (sells, redemptions, LP remainders) per market -(`MarketPnl`). PnL is realized once a market is final and all positions/LP claims are settled -(or via permissionless `realize(market_id)` for pre-close exits). A rolling window of daily -buckets advances lazily, summing net realized PnL across `window_days`. If `window_pnl < -max_drawdown`, -the contract trips into drawdown pause (`DrawdownTripped` instance flag, emitting `DrawdownPause`). -In this mode, buys and creations are blocked, but `agent_sell` remains open (reduce-only) to avoid -trapping positions. Resuming requires admin `acknowledge_drawdown()` before unpausing. Third parties -triggering settlements cannot manipulate loss magnitude, only realization timing. Protocol fees and -external donations are strictly excluded from PnL accounting. - -**Market-creation risk controls (#47).** Market seeds are decoupled from trade caps -via a dedicated `CreationPolicy` (max seed, rolling creation count limit, close horizon -bounds, allowed category bitmask). Stored in instance storage with bounded bucket arrays -(`CREATION_BUCKETS = 24`), creation limits are enforced before any cross-contract calls. -Admin policy updates are tighten-only (`set_creation_policy`), preventing a compromised key -from instantly loosening rules without a redeploy. - -**Blend lending integration & JIT liquidity (#48).** Idle USDC can be supplied to a -configured Blend pool (`set_yield_venue`, `allocate_to_yield`, `recall_from_yield`) up to -`max_allocation` while preserving at least `max_daily` in liquid collateral. Spending entrypoints -(`agent_buy`, `agent_create_market`) use Just-In-Time liquidity (`ensure_liquid`): shortfalls in -liquid reserves trigger an atomic withdrawal from Blend within the same transaction. If pool -utilization prevents withdrawal, the trade reverts cleanly (`YieldWithdrawFailed`, fail-closed). -NAV views (`available_capital`) account for liquid plus supplied capital, alongside `capital_breakdown`. -See [ADR 0006](adr/0006-blend-integration.md). - -The nested-authorization pitfall this design implies, and how it's handled, -is documented at length in `contracts/treasury/src/lib.rs` (see -`authorize_token_pull`) and exercised by -`pitfall_agent_buy_requires_treasury_self_authorization_for_nested_transfer` -in the same file's test module — a test that's been verified to fail -without the fix and pass with it (see the commit history / docs/STATUS.md). - -The global guard is the only check that can be made against the shared -ledger balance: a per-market figure cannot be verified on-chain because -the balance is shared across markets. Donations (anyone sending tokens -directly to the contract) make `balance > TotalLocked`, which is -normal and must not revert. - -#### Treasury cap guarantees - -What the caps actually promise, as checked by -`contracts/integration-tests/tests/treasury_caps_exhaustive` (below), so that -"daily cap" is not over-read. Auth is mocked in that search; wrong-caller -behaviour is covered by each contract's own tests. - -**Guaranteed** (every reachable state of the searched alphabet, I1-I9): - -| | Guarantee | -|---|---| -| I1 per call | A successful `agent_buy` spends at most `max_trade`. A successful `agent_create_market` seeds at most `max_seed` (the creation policy, which may exceed `max_trade`; it is also at most `max_market`). | -| I2 per market | Cumulative agent spend into one market, seed included, is at most `max_market`, for the market's whole life: it is never freed by sells or `close_trade`. `MarketExposure.amount` equals the observed sum of spends. | -| I3 daily | The treasury's reported window (`daily_usage`) never exceeds `max_daily` and equals the spends observed since its reported start. | -| I4 sliding 24h | In **any** interval `[t, t + 86_400)` the agent spends at most `max_daily`. The window is hourly buckets summed over the trade's hour and the 24 hours before it: effectively 24-25h, conservative and never permissive. | -| I5 pause | While the admin has paused, `agent_buy`, `agent_create_market` and `agent_sell` all fail with `Paused`. `close_trade`, `redeem` and `claim_pool_remainder` stay callable: they spend nothing and return capital. (An automatic drawdown pause differs: reduce-only sells stay allowed; not part of this search.) | -| I6 accounting | Treasury token balance = initial - Σ spends + Σ returns (sells, redeems, claims), from the operations' own parameters. | -| I7 sell neutrality | `agent_sell` changes neither the daily window nor any `MarketExposure`. | -| I8 | Net exposure stays within `max_net_exposure`. | -| I9 completeness | An operation within every observable cap succeeds, so a cap is not silently stricter than documented (this is what catches an off-by-one such as `>=` for `>` on `max_market`). | -| Atomicity | A failed call changes no observed quantity (balances, window, exposures, net exposure). | - -**Not guaranteed:** - -- *Admin actions are not agent spending.* `withdraw`, `emergency_withdraw`, - config changes after their timelock, and the market-core admin swapping the - resolver or treasury role all bypass these caps by design. -- *`max_daily` is not a calendar-day cap.* It is a trailing 24-25h cap, so the - agent can be refused a spend that is a few minutes over 24h after a previous - one. It is also not a cap on losses by itself: an agent may spend `max_daily` - every 25 hours, and per market until `max_market`. -- *History: this used to be 2x.* The original fixed window reset to `now` at - the first call after 24h, so an agent could spend `max_daily` just before a - reset and `max_daily` just after (up to `2 * max_daily` in a short span). The - sliding window fixed that; the explorer was written expecting to *report* - that violation (I4) and now finds none. Mutating `BUCKETS` from 25 to 24 - brings I4 back with a depth-5 counterexample (5U spent in one 24h span - against `max_daily = 4U`), pinned by the treasury unit test - `explorer_i4_sequence_stays_within_max_daily`. -- *Prices and breakers are out of scope.* The search lifts the price policy; - slippage, price band and impact are tested separately. -- *The search is bounded.* "Holds up to depth N over this alphabet", not a - proof for all sequences, caps or market counts. - -##### The search - -```bash -cargo test -p integration-tests treasury_caps_exhaustive -- --nocapture # depth 6 -TREASURY_SEARCH_DEPTH=8 cargo test -p integration-tests treasury_caps_exhaustive -- --nocapture -TREASURY_SEARCH_ALPHABET=full ... # the complete alphabet -TREASURY_SEARCH_MARKET_CORE=wasm ... # market-core in the Soroban VM -``` - -Operations: `agent_buy` and `agent_sell` on each market, `agent_create_market`, -`close_trade`, clock advances `{1, 43_200, 86_399, 86_400}` s, and admin -`Pause`/`Unpause`, over two pre-existing third-party markets (and up to two -treasury-created ones). Caps are in units `U` = 100 USDC (`MIN_SEED`): four -configurations (`max_trade/max_market/max_daily` = 2U/3U/4U, all equal to 2U, -a `max_seed` of 3U above `max_trade`, and markets that close after a day so -buys hit `MarketClosed`). Failures are never classified by error code alone -(a market-core error is re-raised under its own code, and e.g. `MarketClosed` -is 9, the same as the treasury's `InsufficientBalance`). - -- *Order:* breadth-first, so the first violation is a shortest one, printed as - a replayable test body (`f.buy(0, 2 * U); f.advance(86_399); ...`). -- *Memoization:* a canonical key of the behaviourally relevant state: pause - flag, `now % 3600`, the window's buckets newest-first, the spends of the last - 25h by exact age (the history I4 needs), and per market the exposure, open - flag, treasury share count (bucketed) and closed status. Absolute time is - never in the key, and market reserves deliberately are not (they only decide - whether a trade clears market-core, which the share bucket and closed status - cover); including them makes almost every trade ordering a distinct state. -- *Symmetry:* the two pre-existing markets are interchangeable, so market - summaries are sorted in the key, and an operation on a market whose - summary equals a lower-indexed one is skipped. -- *Snapshots vs replay:* each child state is built either by re-running the - path on a fresh world or by restoring an `Env` snapshot of the parent. - Measured (`cargo test -p integration-tests -- --ignored branching_benchmark - --nocapture`, depth 3): replay 7.4 ms/operation, snapshot 3.7 ms/operation, - and the gap grows with depth because replay is O(depth). Both produce - identical state counts; snapshot restore is used. Two non-obvious details: - `Env::from_snapshot` always writes a test-snapshot JSON file when the `Env` - is dropped on a *named* thread (every test thread is), which cost 7 minutes - for 4,000 operations, so the search runs on unnamed threads (the SDK skips - the write then); and native contracts are not part of a snapshot, so they are - re-registered with their constructor turned into a no-op. -- *Market-core:* the deep search registers `market-core` natively for speed; - `market_core_wasm_matches_native` runs depth 4 on the vendored wasm and - asserts exactly the same states, operations and growth. The treasury is also - native (the wasm artifact does not exist at `cargo test` time), i.e. the real - contract code, not a mock. -- *Alphabet:* the default `lean` alphabet drops 1s clock ticks, `close_trade`, - seeds that always fail the seed cap, sells with no shares and a second - treasury-created market; `full` is the complete one and is for deeper runs - (below). -- *Results* (depth 6, lean, native market-core, 8 threads): 9,940 abstract - states, 115,208 operations, 103 s; no violation. `full`, depth 5: 7,653 - states, 130,218 operations, 98 s (measured). The work grows about 3.5-5x per - depth, so `full` at depth 6 and `lean` at depth 8 are estimated at roughly - 8 and 20 minutes on 8 cores (not measured). The nightly workflow - (`.github/workflows/treasury-search-nightly.yml`) runs a deeper search and - keeps its output as an artifact; hosted runners have fewer cores, so expect - a few times longer there. -- *Teeth* (recorded in the PR): `new_market > max_market` mutated to `>=` is - reported at depth 2 as an I9 failure (`1U + 2U = 3U` is exactly the cap and - must be allowed); deleting `assert_not_paused` from `agent_buy` is reported - at depth 2 as an I5 violation (`f.pause(true); f.buy(0, 1 * U);`); the - 24-bucket window above is reported as I4 at depth 5. - -### reasoning-registry - -**Views.** `solvency_report(market_id)` returns a `SolvencyReport` -with the market's locked collateral, fees accrued, sets minted, and - outstanding-claims upper bound (`sets_minted + fees_accrued` while -open or unclaimed, derived from `locked` alone after the LP claim), -plus `lp_claimed`. `global_solvency()` returns `(token.balance(contract), -TotalLocked)`.

There is deliberately no admin setter to backfill the -counter for pre-existing markets, because that would be an obvious -privileged backdoor. - -**Fee split and recipient snapshot.** `create_market` snapshots a -`FeeTerms { recipient, protocol_share_bps }` side entry per market, so -`set_treasury` / `set_protocol_fee_share_bps` only affect markets created -after them. Each trade's fee is split once at accrual time -(`math::split_fee`, protocol shares round up so `protocol + lp == fee` -exactly): the protocol portion accumulates in `Market.fees_accrued` and is -swept to the snapshotted recipient by the permissionless `sweep_fees`(old `FeesSwept` event kept for indexers, plus `FeesSweptTo`); the creator -portion accumulates in a `LpFees(market_id)` side entry, claimable any time -(before finality too) via `claim_lp_fees`, and also drained by -`claim_pool_remainder`. Markets created before this change have no -`FeeTerms` entry and fall back to the old behavior: recipient = whatever -`DataKey::Treasury` Holds at sweep time, `protocol_share_bps = 10_000` — -fully backward compatible, no migration transaction needed. The separate -LP balance (rather than adding fees to the reserves) is deliberate: it does -not move `k` or the price and maps directly onto the per-LP fee accumulator -of the future multi-LP design ([wave-issue 02](wave-issues/02-multi-lp-liquidity.md)). - -#### Agent Lifecycle and Trace Annotations (#56) - -The reasoning registry models an explicit lifecycle for agents and traces: -- **Agent lifecycle**: Agents hold `AgentRecord { status: AgentStatus, registered_at: u64 }`. - - `Active`: Registered agent permitted to publish traces. - - `Retired(at)`: Agent gracefully retired by admin (`retire_agent`) or the agent itself (`retire_self`). Retired agents cannot publish new traces, but their existing traces remain valid. Admin may call `reactivate_agent` to return a retired agent to `Active`. - - `Revoked(effective_from, reason)`: Agent revoked by admin (`revoke_agent`) due to compromise or malfeasance. Revocations cannot be reversed or reactivated, preventing history laundering. -- **Trace flagging**: The admin can annotate suspect traces via `flag_trace(trace_id, reason)` and `unflag_trace(trace_id, reason)`. Flags are annotations appended to a bounded history (max 16 entries) and never modify or erase the underlying trace data. -- **Trace verdict**: `trace_verdict(trace_id, received_hash)` evaluates validity in strict precedence: - 1. Not found -> `Err(TraceNotFound)` - 2. Hash differs -> `TraceVerdict::HashMismatch` - 3. Active flag -> `TraceVerdict::Flagged(reason)` - 4. Agent revoked with `trace.published_at >= effective_from` -> `TraceVerdict::AgentRevokedAfter(effective_from)` - 5. Otherwise -> `TraceVerdict::Valid` -- **Semantic tightening of `verify_trace`**: `verify_trace` returns `true` only if `trace_verdict` evaluates to `TraceVerdict::Valid`. Clients wishing to perform bare hash comparison without status checks can query `get_trace`. - -#### Trace Action Validation and Market Reference Integrity (#55) - -Traces reference concrete market actions validated against `market-core`: -- **Canonical Action Vocabulary**: `TraceAction` replaces free-form strings: - | Action | Target Market | Description | - | :--- | :--- | :--- | - | `CreateMarket` | Issued `market_id` | Creation of a new market on-chain | - | `ProposeMarket` | `NO_MARKET` (`u64::MAX`) | Off-chain market proposal prior to creation | - | `Buy` | Issued `market_id` | Purchase of YES or NO shares | - | `Sell` | Issued `market_id` | Sale of YES or NO shares | - | `Skip` | Issued `market_id` | Evaluated market but took no trade action | - | `Redeem` | Issued `market_id` | Redemption of winning or voided shares | - | `ClaimRemainder` | Issued `market_id` | LP reclamation of unredeemed collateral pool | - | `Resolve` | Issued `market_id` | Resolver or oracle resolution attestation | - | `Other(Symbol)` | Issued `market_id` or `NO_MARKET` | Forward-compatible custom action; cannot shadow canonical action names | -- **Market Reference Validation**: - - `market_core.market_count()` is checked via cross-contract read. - - A referenced `market_id` must satisfy `market_id < market_count()`. - - `ProposeMarket` requires `NO_MARKET` (`u64::MAX`), returning `Error::ProposalMustUseNoMarket` if given an actual `market_id`. - - Canonical actions (`Buy`, `Sell`, etc.) reject `NO_MARKET` with `Error::MarketRequired`. - - View function calls to `market_count()` remain functional even when `market-core` is paused. - -#### Merkle-Batched Trace Anchoring (#54) - -To slash per-decision publishing costs for high-frequency trading or extensive skip auditing: -- **Off-chain Batching**: Agents collect up to 4,096 trace hashes off-chain, compute a Merkle tree, and anchor the 32-byte root and manifest CID on-chain via `publish_trace_batch(agent, root, leaf_count, manifest_cid)`. -- **Cryptographic Specifications**: - - **Second-Preimage Resistance**: RFC 6962 domain separation prefixes: leaves hash with `0x00 || trace_hash`, inner nodes hash with `0x01 || left || right`. - - **Odd Node Promotion**: An odd child at any tree layer is promoted unchanged to the next level without duplicating or hashing with itself. When verifying an odd node, no proof element is consumed for that layer. - - **Bounded Proof Length**: With `MAX_LEAVES = 4096`, proof length is strictly bounded to `MAX_PROOF_LEN = 12`.

The threshold is half the target, so - a frequently touched entry is only rewritten when its remaining TTL halves. -- Instance TTL is extended by every entrypoint that reads instance storage - (30-day target, 7-day threshold); pure views over persistent entries stay - read-only so indexer simulations keep read-only footprints. -- The registry additionally refreshes an agent's registration on every - successful `publish_trace`. -- The market-core `Settle` entry (outstanding shares, redemption deadline) is - kept to the long-lived target — 365 days, clamped to `max_ttl()`. A market - whose redemption deadline is more than one network-max TTL away can archive - before it is finalized and needs touches or a restore first; - `finalize_market` works after a restore, and the deadline is computed from - on-chain state (`finalized_at + horizon_secs`), so a late finalization is - still exact. -- The market-core `Oracle` entry and every written `Obs` slot are extended to - the same close-time-aware target as the market's other entries. Unwritten - ring slots are never extended and the read path skips missing slots, so a - half-used ring costs nothing and never fails a read. -- Markets whose `close_time` is further out than `max_ttl` cannot be kept - alive by a single bump and need periodic touches or the keeper described in - [`docs/wave-issues/14-storage-ttl-keeper.md`](wave-issues/14-storage-ttl-keeper.md), - which also covers TTL monitoring and the rent cost model. -### router - -A stateless address book (`RouterConfig { market_core, resolver, -reasoning_registry }`) plus atomic multi-step entrypoints, so a client cannot -half-apply a flow or point it at a hostile resolver (ADR 0009): -`create_and_reveal_signers` / `create_and_reveal_price` (create the market and -reveal its rule in one transaction; the commitment is computed locally from -the spec), `reveal_spec` (the deferred commit-now/reveal-later path), and -`buy_and_publish_trace` (buy through market-core and publish the reasoning -trace together, so a trade cannot drop its trace). It holds no funds and has -no admin. - -### Governance: wiring, admin transfer, timelock - -- **Authenticated wiring (ADR 0006).** `market-core` no longer lets the admin - set the resolver/treasury directly. It `propose_resolver` / - `propose_treasury`; the target must then prove, by calling back - `market_core()`, that it is configured for this market-core before it takes - the role. Every change emits `ResolverProposed`/`ResolverChanged` (and the - treasury equivalents). Deploys are deterministic (`--salt`), so the real - addresses are known before `market-core`'s constructor runs and there is no - placeholder window. -- **Two-step admin transfer (ADR 0007).** All four core contracts (and the - timelock) expose `propose_admin`/`accept_admin`/`cancel_admin_transfer` with - a seven-day expiry. The new admin must accept, so a proposal to an address - the operator does not control never lands; `new_admin` may be a classic - multisig account, a smart-account multisig, or the timelock. -- **Timelock (ADR 0008).** `contracts/timelock` separates the proposer, - canceller, executor and emergency roles and imposes a delay - (`MIN_DELAY = 1 day`) between `schedule` and `execute`, with a seven-day - execution grace and a `cancel` veto. `emergency` bypasses the delay for - `set_paused(true)` / `cancel_proposal` only. Pointing the core contracts' - admin at the timelock (deploy with `USE_TIMELOCK=1`, or migrate with - `scripts/wire-timelock.sh`) removes any single key's ability to change a - live market instantly. - -## Off-chain pieces - -- **x402/**: an Express service selling reasoning traces for ~$0.01 via - `@x402/*`'s exact-payment Stellar scheme.

The trader always quotes - (`quote_buy`) immediately before submitting and derives non-zero - `min_shares_out` / `limit_price_bps` bounds plus a deadline from it. -- **packages/bindings/**: generated TypeScript clients (`scripts/gen-bindings.sh`). - -### Trader sizing - -The trader's optional sized path computes an impact limit by binary-searching -the integer `calcBuy` curve, so it respects the contract's fee and -pool-favoring rounding rather than a floating-point reserve approximation. -It shrinks the fair-value probability by `FAIR_UNCERTAINTY_BPS`, maximizes -expected binary-settlement log wealth with existing YES/NO holdings, and -applies the rational `KELLY_FRACTION` (default 0.25). The result is further -bounded by `TRADE_SIZE_STROOPS`, treasury market/daily/capital headroom and -the market's `MAX_SETS` capacity. A report containing the inputs, intermediate -limits and binding constraint is included in the reasoning trace. `SLIPPAGE_BPS` -sets the minimum share output from the exact integer quote, while the trader -also re-quotes immediately before submission and applies a deadline. - -The limit protects the estimated post-trade marginal price from crossing -`effective fair value - SIZING_BUFFER_BPS`; it cannot guarantee a fill if -another transaction changes the pool between the snapshot and execution. -**Trade bounds and circuit breakers.** Two layers of protection beyond the -share-count slippage parameters: - -- *Deadline + limit price* (#12): `buy_v2` / `sell_v2` take a - `deadline` (ledger **timestamp**, unix seconds) checked before anything - else, and a `limit_price_bps` bounding the **average execution price** - (`collateral_in / shares_out` for buys, `collateral_out / shares_in` for - sells, fee included, compared by cross-multiplication). `0` means "no - limit" for buys; for sells it is trivially satisfied and buys no - protection. The original `buy` / `sell` remain as thin wrappers for - backward compatibility (same body, no bounds). -- *Per-market breakers* (#10): `BreakerConfig { max_impact_bps, band_bps }` - is snapshotted per market from an admin default (`set_default_breaker`, - which rejects `band_bps < max_impact_bps` because that makes one trade - cover the whole band). `max_impact_bps` bounds a single trade's - |post − pre| YES-price move (`>` — a trade moving exactly the cap - passes); `band_bps` bounds |post − ledger-open price|, with the reference - stored in short-TTL **temporary** storage keyed by ledger sequence, so it - resets by itself every ledger. 0 disables either check; legacy markets - have no config and are unaffected. Breaker trips revert with - `PriceImpactTooHigh` / `PriceBandExceeded` and — because Soroban rolls - back an invocation's events on `Err` — emit **no** event (the error codes - and the `would_trip`` / `breaker_config` / `breaker_state` views are the - observability path; see the comment on `check_breakers`). - - *Worst-case lock cost.* The band cannot be ratcheted: the reference is - the ledger-open price, so an attacker who pushes the price to the band - edge only blocks further trades for the rest of that ledger (~5 s) — - and pays the trading fee plus price impact to do it, which are both - retained by the pool. - -**Resolution and payouts.** `resolve(market_id, outcome)` sets the -final outcome once. `redeem` pays `payout` for a winning position and -burns it; `lp_claimed` gates `claim_pool_remainder`, which pays the -creator the residual value of the reserves and zeroes them. Both payouts - are subject to the checked transfer and global solvency guard. - -### IPFS trace storage - -In live mode the agents store traces with `IpfsTraceStore` -(`agents/core/ipfs-store.ts`; selected by `TRACE_STORE`, see -`agents/core/trace-store-factory.ts`). The CID that goes on-chain in -`publish_trace(..., ipfs_cid)` is permanent, because `Trace` entries have no -update path. So the agent computes the CID itself and does not trust any -pinning provider to name the content: - -- **Raw CIDv1.** The CID is a CIDv1 with the `raw` codec (`0x55`) and a - sha2-256 multihash over the exact UTF-8 bytes `buildTrace` hashed - (base32 lowercase, `bafkrei…`, 59 characters). Its multihash digest is - therefore *equal to* `trace_hash`. A default `ipfs add` (dag-pb/UnixFS, - chunked) would hash a protobuf wrapper instead and break that property, - so kubo is called with `cid-version=1&raw-leaves=true&hash=sha2-256` and a - 1 MiB chunker, and traces are limited to one 1 MiB block. -- **Providers are verified, not trusted.** Any provider that reports a CID - different from the local one (compared by value with `CID.equals`, not by - string) fails the whole `put`. Pins go to a kubo RPC node and optionally an - IPFS Pinning Service API (`POST /pins`, polled until `pinned`). Each - provider is retried with jittered backoff, and at least `IPFS_MIN_PINS` - must *confirm* the pin. Queued pins count only with `IPFS_ACCEPT_QUEUED=1`. -- **Retrievability is checked.** Before `put` resolves, the agent GETs - `${IPFS_GATEWAY_URL}/` (the gateway x402 also reads), following - redirects, with a byte cap and a timeout, and re-checks `sha256(body)`. - The trade or market creation is only submitted after this succeeds. If - pinning fails, the action is skipped and logged. -- The market-maker also pins a small metadata document (question, category, - close time, trace hash and CID) and sets the market's `meta_uri` to - `ipfs://`. `local://` URIs remain only in dry-run, or in live mode with - `ALLOW_LOCAL_TRACE_STORE=1`. - -**Verifying without fetching.** A buyer holding `(trace_hash, ipfs_cid)` from -the registry can decode the CID: version 1, codec `0x55`, multihash code -`0x12` (sha2-256), length 32. The 32 digest bytes must equal `trace_hash`. -With `multiformats`: -`Buffer.from(CID.parse(cid).multihash.digest).toString("hex") === trace_hash`. -After fetching, `sha256(body) === trace_hash`, as `x402/trace-verification.ts` -checks, proves the bytes are the ones the agent committed to. - -### Event triggers (agents) vs. the event indexer - -`agents/core/events/` (#105) lets agents react to contract events instead -of waiting for their next scheduled run. It is a **trigger system, not an -indexer**, and the two must not be confused: - -| | Event triggers (`agents/core/events`) | Event indexer (`docs/wave-issues/06-event-indexer.md`) | -| --- | --- | --- | -| Purpose | Wake an agent when something it cares about happens | Durable, queryable history for UIs and analytics | -| Storage | One checkpoint per network and contract set: `{cursor, lastLedger}` plus recently processed event ids, in `EVENTS_STATE_DIR` | Every event, in Postgres | -| History | None. Starts at the latest ledger; never replays | Replayable from any ledger it has stored | -| Retention gap | Detected; triggers a full state resync from chain reads | Is the thing it exists to cover | -| Source of truth | Chain state, re-read before every action | Its own tables | - -Flow: `EventSubscriber` polls `getEvents` (cursor pagination, filters -checked against the RPC's limits, failed contract calls dropped) and hands -each page to the `Dispatcher`. Events are decoded with the binding specs -(`decode.ts`, via the SDK's `Spec.parseEvent`) into a typed -`OracleDeskEvent`, with an `Unknown` variant for anything else. - -- **At-least-once delivery.** A page's checkpoint is written only after - every handler finished (or the event was dead-lettered). A crash in - between redelivers the page, so handlers are idempotent and an LRU of - processed ids, saved with the checkpoint, drops repeats. -- **Ordering.** One market's events run in order; different markets run - concurrently up to `EVENTS_CONCURRENCY`. -- **Failures.** A handler is retried with exponential backoff up to - `EVENTS_MAX_ATTEMPTS`, then the event goes to - `/dead-letter.jsonl` and the page moves on. -- **Idle polls** still advance `lastLedger`, so a quiet stretch is not - mistaken for a retention gap. - -Handlers (`handlers.ts`): `TradeReevaluate` queues a market for the trader -after a trade of at least `EVENTS_TRADE_THRESHOLD` stroops (re-reading the -market first); `ProposalWatch` alerts on a `ResolutionProposed` where the -treasury holds a position and the resolver still reports the proposal as -standing (cancellations emit no event), with the dispute deadline computed -from the proposal's ledger timestamp; `FinalityTracker` marks markets final -on `MarketResolved`, `ResolutionFinalized` or `PriceResolution`; and the -resync handler re-evaluates every tradable market after a gap. - -`npm run trader -- --follow` runs this loop (`runtime/follow.ts`); without -`--follow` the trader behaves exactly as before. - -### Cross-market arbitrage (agents, #108) - -Independent FPMM pools can price related markets inconsistently. With -`ARB_ENABLED=1` the trader runs an `arbitrage` task -(`runtime/tasks/arbitrage.ts`) over the relations in `ARB_RELATIONS_FILE`: - -```json -{ "relations": [ { "id": "btc-100k-implies-90k", "type": "implies", "a": 12, "b": 7, - "resolution": { "a": { "mechanism": "price", "source": "reflector:BTC/USD" }, - "b": { "mechanism": "price", "source": "reflector:BTC/USD" } }, - "voidCorrelation": "joint", "maxCloseSkewSecs": 0 } ] } -``` - -- **Relations** (`core/strategies/arbitrage.ts`): `implies` (P(A) <= P(B)), - `complement` (P(A) + P(B) = 1) and `exclusive` (P(A) + P(B) <= 1). A - relation is rejected unless both markets exist and are open, their close - times are within `maxCloseSkewSecs`, and both declare the *same* - resolution mechanism and source; a declared `resolutionHash` must equal - the market's on-chain commitment. The file's canonical sha256 (the graph - hash) is recorded in every trace. -- **Planning**: for each pair of legs, a payoff table over every outcome the - relation allows, plus void scenarios (`joint`: both void together; - `independent`: either may void alone, paying half per share), gives the - worst-case payout, measured on top of existing treasury holdings. Costs - are exact integer FPMM collateral (`collateralForShares`: fees, price - impact and rounding). The share count is found by integer ternary search - and a +/-64 verification scan, inside `max_trade`, remaining `max_market` - headroom, the rolling `max_daily` and `ARB_MAX_NOTIONAL`, and must clear - `ARB_MIN_PROFIT_STROOPS` and `ARB_MIN_PROFIT_BPS`. -- **Risk** (`core/risk.ts`, `checkArbPlan`): treasury caps and existing - exposure; `ARB_MARKET_HEADROOM_BPS` of each market's `max_market` kept free - for later hedges; `ARB_MAX_UNHEDGED_STROOPS` caps the first leg, which is - the exposure left if the second never fills; `ARB_MAX_OPEN_LEGS` and - `ARB_MAX_UNWIND_RETRIES` bound concurrent legs and unwind attempts. -- **Execution** (`core/strategies/arb-executor.ts`): treasury calls are not - atomic, so the legs are sequential. The less liquid market goes first, - re-quoted and bought with `min_shares_out` = the planned shares. The second - market is then re-read; if its cost rose by more than `ARB_MAX_LEG_LOSS` - the first leg is sold back with `agent_sell`, otherwise the second leg is - bought. Every step is journaled before and after submission in - `ARB_JOURNAL_FILE`, and the next run finishes or unwinds any plan a crash - interrupted, settling ambiguous submissions from the treasury's positions. - A trace with the relation, graph hash, snapshots, plan and leg results is - published when a plan completes or is unwound. Dry-run only plans and logs. - -**Residual risks.** Between the legs the treasury holds one side naked: a -fast move can cost up to `ARB_MAX_LEG_LOSS` plus the unwind's price impact, -and if every unwind attempt fails the leg stays open (`ARB_UNHEDGED` is -logged and the plan closes as `unwind-failed`). The relation file is -trusted: a wrong relation produces confident, wrong trades, which is why -compatibility must be declared and is checked against the chain. - -## Known limitations (see docs/STATUS.md for the full, current list) - -- Testnet only; unaudited. -- No indexer yet — anything needing historical events beyond RPC's - retention window has no on-chain-native way to query them. -- Agent-vs-agent liquidity: nothing here stops multiple independent agent - deployments (this repo's or a fork's) from trading against the same - market-core markets; the treasury's caps bound one agent deployment's own - risk, not systemic market behavior. -- MAX_SETS griefing via `split`: an attacker can split up to `MAX_SETS` and - block further `buy` calls (`MarketTooLarge`) at the cost of locking that - much collateral, then merge out risk-free. See the split/merge section - above for why the shared cap is kept. - -### x402 payment preparation, settlement and replay - -One HTTP resource server advertises all effective Stellar networks. Each -facilitator client is scoped to its configured network even if `/supported` -advertises others; API keys never cross those scopes. Startup defaults to -requiring every configured network. `X402_REQUIRE_ALL_NETWORKS=false` probes -and drops unavailable networks, logs structured warnings, and still refuses -startup if none remain. The process awaits initialization before listening. - -For a fresh purchase the trace path is: registry lookup → bounded IPFS fetch → -raw-byte hash verification → JSON parse and response encoding → durable ledger -claim → facilitator verification → durable `settling` transition → settlement → -durable receipt → delivery. No trace bytes are sent before settlement succeeds. -`@x402/*` are pinned to 2.26.0; requirements and scheme capabilities support only -`authorization`. Upfront payloads are rejected. `X402_TRACE_LOAD_TIMEOUT_MS` -(default 10 seconds) bounds the entire preparation phase, including repository -lookup and body reads, and must be less than half `X402_MAX_TIMEOUT_SECONDS` -(default 60). An unpaid unknown trace gets 404 rather than a payment challenge; -this permits enumeration of IDs that are already public in the registry. - -The default ledger is SQLite (`X402_LEDGER_PATH`, default `.x402-ledger.sqlite`), -with WAL, FULL synchronous durability, a unique payment ID and compare-and-set -state updates. `X402_LEDGER=memory` provides the same interface for tests or -explicitly ephemeral sessions. A payment ID hashes the network plus the inner -Stellar transaction hash; fee-bump wrappers and base64 whitespace do not create -new purchases. A stored claim binds it to trace, recipient, network, amount, -asset and requirement settings before verification. Concurrent duplicates get -409 with `Retry-After: 2`; cross-resource or changed-price reuse gets 409. - -States are `verifying → settling → settled → delivered`, with `failed` for -known failures and `indeterminate` for timeouts or interrupted settlement. -The durable transition runs outside SDK hooks because 2.26.0 logs thrown hook -errors and can continue. No ledger write means no settlement attempt. Startup -marks interrupted verifying/settling rows indeterminate; it never retries them. -Operators must inspect/reconcile these against the chain before taking action. -A settlement timeout returns 502 without content. Other SDK failures retain -standard HTTP instructions and payment challenge headers. - -Settled/delivered retries return the original stored body and PAYMENT-RESPONSE -without another facilitator call or gateway fetch.

Failure to obtain that -anchor fails closed. Database/state conflicts are never auto-settled again. - -`GET /admin/payments/:paymentId` requires `Authorization: Bearer X402_ADMIN_TOKEN` -and is disabled if unset. It returns purchase state and transaction/payer fields, -with raw trace bytes, response content and requirement keys redacted. The SQLite -file is permissioned to its owner and git-ignored. Back it up as sensitive -purchase history. This design supports one service process; shared multi-instance +# Architecture + +See the top-level diagram in [README.md](../README.md#architecture) for the +system at a glance. This doc goes one level deeper into each contract's +responsibilities and the invariants that hold across them. + +## Contracts + +### market-core + +The hub: every binary market lives here as one entry in persistent storage, +keyed by `market_id`. Pricing is a Gnosis-style constant-product FPMM over +internal YES/NO share accounting — no external LP token, no AMM pool +contract per market. `contracts/market-core/src/math.rs` is the entire +pricing engine, pure integer arithmetic, no `Env` dependency, so it's +natively unit-testable and mirrored line-for-line in +[`model/fpmm_model.py`](../model/fpmm_model.py) and +`agents/core/fpmm.ts` for property testing and off-chain quoting. + +**Decimals.** The collateral token's `decimals()` is read once in +`__constructor` (rejecting anything above 18 with `UnsupportedDecimals`) and +stored in instance storage; `get_config` exposes it as `Config.decimals`. +The market-size bounds are derived from it rather than hardcoded: +`min_seed = 100 * 10^d` and `max_sets = 1e8 * 10^d` (`math::bounds_for_decimals`), +so a 7-decimal USDC market keeps the old 100 USDC / 100M USDC limits while an +18-decimal token gets 100 / 1e26 raw units. Because `max_sets` can now reach +1e26, `mul_div_floor` / `mul_div_ceil` use 256-bit intermediates (a no_std +`u128x2` widening multiply/divide in `math.rs`) so a result that fits in +`i128` is always returned exactly, regardless of the product's size. +The widening helpers live in a `no_std` `wide` module inside `math.rs` with +no `soroban_sdk` imports, so the arithmetic stays natively testable and the +Python/TypeScript mirrors can reproduce it bit-for-bit. + +**Split and merge (complete-set primitives).** Two pool-free entrypoints +convert between collateral and complete sets, modelled on Gnosis's +Conditional Tokens `splitPosition` / `mergePositions`: + +- `split(holder, market_id, amount)` pulls `amount` collateral from `holder` + and credits `amount` YES **and** `amount` NO to `holder`'s `Position`. + Requires `MarketStatus::Open` and `now < close_time` (reuses + `assert_tradable`) plus `assert_not_paused`; after close, splitting has no + purpose and would open timing games. +- `merge(holder, market_id, amount)` debits `amount` YES and `amount` NO + (rejecting with `InsufficientShares` if either leg is short) and pays + `amount` collateral back to `holder`. Requires `MarketStatus::Open` but is + **allowed after `close_time` and while paused**: merging is a pure exit + that cannot harm the pool, and letting holders de-risk while the resolver + is slow is valuable. This asymmetry with `split` is deliberate. + +Neither touches `reserve_yes`, `reserve_no` or `fees_accrued`, and neither +charges a fee. Both emit `SetsSplit` / `SetsMerged` (`market_id`, `holder` +as topics, `amount` as data) so indexers can track positions. `split` +performs its state writes before the token transfer, matching `buy`. +`math::merge_max(yes, no) = min(yes, no)` (mirrored in the Python model and +the TS agent core) backs the `quote_merge_max(market_id, holder)` view for +frontends offering "merge all". + +The TS mirror lives in `agents/core/fpmm.ts` as `mergeMax(yes, no)` and must +stay syntactically valid and in lockstep with `math::merge_max`; the agents +test suite exercises known values against the Rust and Python implementations. + +**Invariant proof for split/merge.** Let `S = sets_minted`, +`R_y, R_n` be the reserves and `Σpos.yes, Σpos.no` the summed holder legs. + +- *Split* adds `amount` to `S`, to `Σpos.yes` and to `Σpos.no`, so + `R_y + Σpos.yes == S` (and the NO twin) is preserved. The collateral + balance grows by exactly `amount`, so `balance == S + fees_accrued + + lp_fees` holds. +- *Merge* subtracts `amount` from `S` and from both sums, and pays out + `amount` collateral; the same two equalities are preserved. +- *Settlement.* Resolved(Yes) pays `R_y + Σpos.yes = S`. Void pays + `Σ floor((y_i + n_i)/2) + floor((R_y + R_n)/2) <= (Σ(y_i + n_i) + R_y + + R_n)/2 = S`. Split can increase the number of holders each losing up to + 0.5 unit to flooring, but the total is bounded by `S` — the + `void_total_payout_never_exceeds_sets_with_split` test asserts this. + +**MAX_SETS griefing (split).** `split` is bounded by `math::MAX_SETS` +(`MarketTooLarge` above it), the same cap `buy` enforces. An attacker can +therefore split up to `MAX_SETS` and block further `buy` calls at the cost +of locking that much capital, then merge out risk-free. Decision: keep the +shared cap rather than add a separate per-market split cap or exclude split +sets from the `buy` limit. A separate cap would let `sets_minted` exceed +`MAX_SETS` (breaking the settlement bound above), and excluding split sets +from the `buy` limit would let `sets_minted` grow unbounded. The griefing +cost is locking the full `MAX_SETS` of collateral, which is expensive and +recoverable only by the attacker's own merge; the alternative designs are +worse. This is documented as a known limitation. + +**Pause semantics for merge.** Because `merge` works while paused, a paused +contract can still pay out collateral. This is intentional (a pure exit +cannot harm the pool) and is recorded in `SECURITY.md`. + +**`sell` accounting.** `sell` now uses `checked_sub` for `sets_minted` +(previously an unchecked `-=`), so a bug can never drive `S` negative and +break the settlement bound. + +**Solvency invariant** (holds after every state transition — see the test +suite for the ones exercised): the contract's own SEP-41 token balance for a +market equals `sets_minted + fees_accrued + lp_fees` (`fees_accrued` is the +protocol's pending share of trading fees, `lp_fees` the creator's — see the +fee split below), and `reserve_yes + Σ(user yes positions) == sets_minted` +(symmetrically for `no`). + +**Market size bound.** A market's seed and total sets are bounded by +`max_sets = 1e8 * 10^decimals` (100M tokens at the collateral's precision); +`buy` reverts with `MarketTooLarge` past it. `settle_value` sums YES+NO with +checked addition, so the bound also keeps settlement arithmetic in `i128`. + +**Fee split and recipient snapshot.** `create_market` snapshots a +`FeeTerms { recipient, protocol_share_bps }` side entry per market, so +`propose_treasury` / `set_protocol_fee_share_bps` only affect markets created +after them. Each trade's fee is split once at accrual time +(`math::split_fee`, protocol shares round up so `protocol + lp == fee` +exactly): the protocol portion accumulates in `Market.fees_accrued` and is +swept to the snapshotted recipient by the permissionless `sweep_fees` +(old `FeesSwept` event kept for indexers, plus `FeesSweptTo`); the creator +portion accumulates in a `LpFees(market_id)` side entry, claimable any time +(before finality too) via `claim_lp_fees`, and also drained by +`claim_pool_remainder`. Markets created before this change have no +`FeeTerms` entry and fall back to the old behavior: recipient = whatever +`DataKey::Treasury` holds at sweep time, `protocol_share_bps = 10_000` — +fully backward compatible, no migration transaction needed. The separate +LP balance (rather than adding fees to the reserves) is deliberate: it does +not move `k` or the price and maps directly onto the per-LP fee accumulator +of the future multi-LP design ([wave-issue 02](wave-issues/02-multi-lp-liquidity.md)). + +**Trade bounds and circuit breakers.** Two layers of protection beyond the +share-count slippage parameters: + +- *Deadline + limit price* (#12): `buy_v2` / `sell_v2` take a + `deadline` (ledger **timestamp**, unix seconds) checked before anything + else, and a `limit_price_bps` bounding the **average execution price** + (`collateral_in / shares_out` for buys, `collateral_out / shares_in` for + sells, fee included, compared by cross-multiplication). `0` means "no + limit" for buys; for sells it is trivially satisfied and buys no + protection. The original `buy` / `sell` remain as thin wrappers for + backward compatibility (same body, no bounds). +- *Per-market breakers* (#10): `BreakerConfig { max_impact_bps, band_bps }` + is snapshotted per market from an admin default (`set_default_breaker`, + which rejects `band_bps < max_impact_bps` because that makes one trade + cover the whole band). `max_impact_bps` bounds a single trade's + |post − pre| YES-price move (`>` — a trade moving exactly the cap + passes); `band_bps` bounds |post − ledger-open price|, with the reference + stored in short-TTL **temporary** storage keyed by ledger sequence, so it + resets by itself every ledger. 0 disables either check; legacy markets + have no config and are unaffected.

Both preserve the solvency invariant by +construction; the position mapping is unchanged down to the "remove +zero entries" rule. + +**Runtime enforcement.** The invariant is no longer just a test +property. Every collateral movement in market-core goes through a +checked transfer helper that measures the actual balance delta, and a +global locked-collateral counter is updated on every inflow and outflow. +Every market shares one token balance held at the market-core address, so +the contract no longer trusts that every `token.transfer` moved exactly +the requested amount. + +#### Runtime solvency accounting + +**Economics.** LP worst-case loss, the rounding argument and the no-arbitrage +theorem for this exact integer math are in [fpmm-economics.md](fpmm-economics.md) +(executable checks: `model/fpmm_bounds.py`). + +**Resolution commitment**: `resolution_hash` is fixed at `create_market` +time — see [ADR 0001](adr/0001-resolution-commitment.md) for why. + +Lifecycle: `create_market` → `buy`/`sell` (while open; `buy_v2`/`sell_v2` +with bounds) → `resolve` or `void_market` (resolver-only) → `redeem` per +holder, `claim_pool_remainder` for the creator/LP, `sweep_fees` +(permissionless) to the snapshotted fee recipient. Positions and LP +ownership can change hands at any point via `transfer_position` / +`transfer_lp`. While open, `split`/`merge` convert between collateral and +complete sets without touching the pool (`split` before `close_time`, +`merge` any time before resolution, including while paused). After +finality, `redeem` handles both legs; `merge` is not used post-resolution. +`finalize_market` (permissionless, after the redemption deadline) closes the +market and sweeps the residual. + +A per-market `SettleState` side entry (views `settle_state` and +`redeem_deadline`) tracks user-held outstanding shares, the finality +timestamp, a per-market redemption horizon snapshotted at creation (default +365 days; admin-set default bounded to 180–1825 days), what has already been +paid out, and whether the market is closed. `redeem` and +`claim_pool_remainder` maintain it on every payout. Once +`finalized_at + horizon_secs` has passed, anyone can call `finalize_market`: +it reserves exactly what the outstanding shares can still claim +(`settle_upper` — for void markets the aggregate floor, which is at least +the sum of the per-holder floors) plus any unclaimed LP remainder, then +sweeps the market's **entire** remaining balance — expired user claims, +void rounding dust, the unclaimed remainder and accrued fees — to the +treasury, marks the market `RedemptionClosed`, and zeroes the market's +balance. A holder who redeems before the deadline is paid the exact +`settle_value` they would have received without finalization; expired claims +go to the treasury rather than the LP, so the LP cannot profit from +suppressing redemptions. Markets created before this bookkeeping existed +have no `Settle` entry: they have no deadline and cannot be finalized +(`NotSupported`), and stay redeemable through the old paths. + +A per-market **TWAP accumulator** records a time-weighted price. Every trade +(`buy`/`sell`) folds the market's pre-trade price into a cumulative +`price × time` value before reserves move (Uniswap-v2 semantics), with state +in `Oracle(id)` and a 16-slot ring of `Obs(id, k)` observations so the +`Market` entry's XDR is unchanged. `observe(id, seconds_ago)`, +`twap(id, window_secs)` and `price_cumulative(id)` read it back: between two +bracketing observations the cumulative is interpolated (exact — the +cumulative is piecewise-linear between trades, since no price moves inside +an interval), past the newest observation the last price +is extended counterfactually, and a time earlier than the oldest surviving +observation fails with `ObservationTooOld`. Same-timestamp trades only +refresh the spot price — nothing is accumulated within one ledger, so a +manipulator cannot move the TWAP without holding the price across a ledger +boundary. Markets created before the accumulator existed return +`NotSupported` from these views. + +The contract maintains a global counter and a per-market figure: + +- `DataKey::TotalLocked` (instance, `i128`, initialised to `0` in the + constructor): the sum over all markets of collateral the contract + still owes (unredeemed claims plus unswept fees). +- `DataKey::Locked(market_id)` (persistent, `ii128`, same TT\ policy as + `Market`): the per-market share of that obligation. It is kept in a + separate entry so the `Market` XDR layout does not change. + +Every collateral movement goes through `transfer_in` / `transfer_out`, +which measure the actual balance delta around the transfer: + +Independent resolution modes, all ultimately calling +`market_core.resolve(market_id, outcome)`: + +- **PriceThreshold**: reads a [Reflector](https://reflector.network) SEP-40 + price feed at a timestamp aligned to the feed's `resolution()` grid at or + *before* the market's `close_time` (`close_time - close_time % resolution`), + walking back along the grid — at most `MAX_LOOKBACK_RECORDS` (12) records, + and never past `max_staleness` — until it finds a published record. A feed + with `resolution() == 0` or a non-positive published price is `InvalidPrice`; + a grid the feed simply has no record on (or one the bounded walkback + exhausts) is `StalePrice`, so operators should resolve before the window + closes and guardians may void via the `OracleUnavailable` path after grace. + The legacy `Price` spec compares the threshold in feed-native units (raw + integer, no scaling); the decimal-explicit scaled spec + (`ScaledPriceConfig`) carries + `threshold_decimals` and rescales both sides to the coarser of + `decimals()` and `threshold_decimals` before comparing — see ADR 0001, + "Price threshold units". `preview_price(market_id)` reads the feed's newest + record (`lastprice`) read-only, without resolving or storing anything. + Anyone may first pin the grid read with `snapshot_price` (legacy and hybrid + specs only; scaled markets reply `WrongMode` — see "Oracle history retention" + below). +- **PriceTwap**: the time-weighted-average price threshold (issue #27, + `TwapConfig` + `register_twap_spec`/`resolve_twap`).

The average is an integer-only, checked + `i128` sum weighted by time-to-next-sample (the last sample's weight runs + through `close_time` inclusive), floored before the threshold comparison, + and emitted as `TwapResolution` alongside the unchanged + `PriceResolution`/`V2` pair. It commits through its own domain-tagged + preimage (ADR 0001, "TWAP resolution variant") and is `WrongMode` for + `snapshot_price`/`preview_price`, which pin single prints.

Each outcome has its own counter and signers are deduplicated + per `(outcome, signer)`; the first outcome to reach threshold is + proposed and later `Yes`/`No` quorums never move it, except that an + `Invalid` quorum replaces a pending `Yes`/`No` proposal and restarts the + dispute window. `attest` requires `close_time` to have passed, which is + what keeps a committee void (market-core's `void_market` has no close-time + guard) from happening early.

If the oracle feed fails or is unavailable + after `close_time + fallback_delay`, anyone can call `open_fallback(market_id)` to + allow fallback signers to propose and attest.

Look the current values +up from Reflector's documentation or the feed contract itself; do not +assume them. A price market nobody resolves before its `close_time` record +ages out would otherwise return `PriceUnavailable` forever and could only be +voided. + +`snapshot_price(market_id, caller)` closes that gap. Anyone may call it +after `close_time` while the market is unresolved; it reads the committed +feed exactly as resolution does (on the `resolution()` grid, at or before +`close_time`), validates it with the same rule +(`validate_price`: not after close, price strictly positive, no older than +`max_staleness`), and +stores it as a `PriceSnapshot`. An invalid read is never stored, and the +first valid snapshot wins (`SnapshotExists`): the answer for a fixed +`(asset, close_time)` is deterministic, so this deliberately prefers +determinism over an oracle later rewriting history. Every price path +(`resolve_price`, `expire_market`, `open_fallback`, and the guardian's +`OracleUnavailable` check) uses a stored snapshot before the live feed and +then skips the oracle call. `PriceResolutionV2` adds `from_snapshot`; the +original `PriceResolution` is still emitted alongside it for one release. + +Operators and agents should call `snapshot_price` within one oracle period +of `close_time` (CLI: `stellar contract invoke --id $RESOLVER -- snapshot_price +--market_id --caller
`). A late snapshot is still accepted as +long as the oracle has the record. + +#### Bonded disputes (`SignersDisputable`) + +A `SignersDisputable` spec adds an optimistic challenge to Attested mode. +While a proposal's dispute window is open, anyone can `dispute` it by +escrowing `dispute_bond` of the collateral token in the resolver. That +freezes `finalize_signers`, `attest`, `cancel_proposal` and `expire_market` +(`DisputeActive`) and escalates to the authority committed in the spec: the +guardian (`settle_dispute`) or a `k`-of-`n` committee disjoint from the +signers (`escalation_attest`). Upholding the proposal resolves to it and +forfeits the bond to market-core's treasury; any other ruling resolves to the +verdict (or voids for `Invalid`) and returns the bond. If nobody rules within +`escalation_timeout` of the dispute, anyone may `expire_dispute`: the market is +voided and the bond refunded. `guardian_void_market` during a dispute also +refunds it. Bonds leave escrow only via the permissionless +`claim_dispute_bond` (pull, so a payee that cannot receive cannot block +settlement); the resolver's token balance always equals the bonds it still +holds. + +```mermaid +stateDiagram-v2 + [*] --> SignersPending: register_disputable_spec + SignersPending --> SignersPending: attest (proposal at threshold) + SignersPending --> Finalized: finalize_signers (window elapsed) + SignersPending --> Disputed: dispute (window open, bond escrowed) + Disputed --> Finalized: settle_dispute / escalation_attest (k votes) + Disputed --> Finalized: expire_dispute (timeout, void, refund) + Disputed --> Finalized: guardian_void_market (void, refund) + SignersPending --> Expired: expire_market (no pending proposal) + Finalized --> [*]: claim_dispute_bond pays the payee +``` + +**Rewards, honestly:** a winning disputer only gets their bond back. The +resolver holds no funds besides bonds, so there is nothing to pay a reward +from until signers also post bonds (signer staking is separate work). The +incentive to dispute is therefore protecting one's own position, not profit. + +Liveness: `resolution_deadline` is `close_time` + 30 days. After it anyone can +call `expire_market`, which resolves the market if it still can be (valid +price feed) and otherwise voids it through market-core, so collateral is never +locked behind a missing reveal or a silent committee. See ADR 0001. + +#### Attestation evidence linking (`reasoning-registry`) + +Attestation votes can be bound to cryptographic traces recorded in `reasoning-registry`. +When configured via `set_evidence_config(min_policy, registry)`: +- Signers call `attest_with_evidence` citing `(trace_hash, reasoning_hash)`. +- The resolver queries `reasoning-registry` via cross-contract call to confirm that + the trace has been published and satisfies `EvidencePolicy` (e.g. `RawBytes` vs `ReasoningBounded`). +- Each `trace_hash` can only be cited once per market (`EvidenceUsed` prevents replay). +- An audit trail of cited traces is preserved on-chain (`evidence_count`, `evidence_at`). + +#### Constrained guardian powers and audit trail + +To limit administrative discretion: +- **Dispute window bounds**: `cancel_proposal` can only be executed while a dispute window + is actively open (`DisputeWindowClosed` error if closed). +- **Grace periods for voiding**: `guardian_void_market` cannot void arbitrarily; it requires + `close_time + REVEAL_GRACE_SECS` (3 days) for unrevealed specs, `close_time + ORACLE_GRACE_SECS` + (1 day) for failing price feeds, and `close_time + SIGNER_GRACE_SECS` (7 days) for unresponsive + signers (`GracePeriodNotElapsed` error if called early). +- **Rate limiting**: `MAX_CANCELS_PER_MARKET = 2` prevents infinite cancellation griefing. +- **Audit trail**: Every guardian cancellation or void requires a typed `GuardianReason` + (`StaleOracleFeed`, `CompromisedSigner`, `AmbiguousSpec`, `LivenessFailure`, `Other`), + and emits a `GuardianAction` event with full contextual metadata. + +The resolver never depends on `market-core`'s Rust crate — see +[ADR 0002](adr/0002-cross-contract-calls.md) for why, and what that trades +off. + +| Site | Direction | `Locked` / `TotalLocked` delta | +|--------------------------|------------------|------------------------------| +| `create_market` | creator -> contract | `+= seed_amount` | +| `buy` | trader -> contract | `+= collateral_in` (net + fee) | +| `sell` | contract -> trader | `-= collateral_out` | +| `redeem` | contract -> holder | `-= payout` | +| `claim_pool_remainder` | contract -> creator| `-= payout` | +| `sweep_fees` | contract -> recipient| `-= amount` | + +Notes on the rules: + +Holds the agents' pooled USDC and is the *only* path that spends it: an +agent calls `agent_create_market` / `agent_buy` / `agent_sell` / +`agent_buy_v2` / `agent_sell_v2` (always naming itself as the first +`agent` argument), the treasury checks the agent's role and its own +per-trade/per-market/daily caps plus the price limits, then calls +`market-core` itself as the trader/creator. This means the caps are a real on-chain limit on what the +automated agent can deploy — an agent's own key calling `market-core` +directly would just be trading its own separate funds, not bypassing a cap +on the treasury's money. The `*_v2` twins forward the same caps plus +market-core's deadline / limit-price bounds, so a revert from either layer +leaves the caps unchanged (the whole invocation is atomic). + +Treasury `agent_split` / `agent_merge` forwarders are **not** implemented +yet (a non-goal of the split/merge change); agents that need the primitives +call `market-core` directly today. They can be added later as thin wrappers +that reuse the existing caps. + +**Agents.** The treasury keeps a registry of up to `MAX_AGENTS = 16` agents, +each with an `AgentPolicy { roles, max_trade, max_daily, active }`. Roles are +a bitmask: `ROLE_CREATE` (`agent_create_market`), `ROLE_TRADE` (`agent_buy`, +`agent_sell` and their `_v2` twins) and `ROLE_SETTLE` (`redeem`, +`claim_pool_remainder`, `close_trade`, `agent_claim_lp_fees`, the `legacy_*` +recovery calls). The constructor registers its `agent` with every role and +the global caps; `scripts/deploy-testnet.sh` then proposes a separate maker +(`CREATE | SETTLE`) and trader (`TRADE | SETTLE`), so a leaked trader key +cannot create markets and a runaway trader cannot spend the maker's budget. +An agent's `max_trade` and `max_daily` sit under the global caps; both levels +are checked on every spend, and each agent has its own sliding daily window +(`agent_daily_usage`). `TradeAuthorized.agent` names the acting agent. +Positions are still pooled: market-core only ever sees the treasury, so the +per-agent state is usage, not ownership. `remove_agent` deactivates at once +(usage history kept), but at least one active `ROLE_SETTLE` agent must always +remain so open positions can be settled. Narrowing an active agent's policy +applies at once; adding, reactivating or widening one goes through the +timelock below (`set_agent` → `execute_agent` after `config_delay`). +`get_config()` survives as a deprecated view in the old `RiskConfig` shape, +whose `agent` is the first registered agent; a stored pre-registry config is +migrated lazily into `GlobalConfig` plus one full-role agent. + +**Caps.** Four limits apply to every buy and market creation: + +- `max_trade`: per call. +- `max_market`: lifetime capital ever committed to one market. Never freed, + not by sells, redemptions or `close_trade`. +- `max_daily`: a **sliding** 24h limit. Usage is kept in 25 hourly buckets + (`UsageWindow`, instance storage); a trade at hour `h` is accepted only if + buckets `h-24 ..= h` plus the trade stay within `max_daily`. Every real + 24h interval falls inside those 25 hours, so no trailing 24h ever exceeds + the cap. The rounding is conservative: a trade keeps counting for 24-25h. + (The previous fixed window reset lazily, so `max_daily` could be spent + just before a reset and again just after it.) `daily_usage()` keeps its + `DailyUsage` shape (`day_start` is now the start of the oldest counted + hour) and is side-effect free; `daily_usage_detail()` returns the buckets + and `daily_headroom()` the remaining allowance. +- `max_net_exposure`: capital *currently* deployed across all markets. The + treasury records collateral in (buys, creations) and out (sells, + redemptions, pool remainders, LP fee claims) per market (`NetPosition`) + and keeps a running `net_exposure() = sum(max(0, in - out))`. Profit in + one market floors at zero and never offsets another. A sell frees net + headroom but not lifetime headroom; `close_trade` changes neither; + `migrate_market` drops the market from net accounting. Enforcement uses + only these local counters (no extra cross-contract call on the hot path) + and never a pool price: a spot-valued cap would let anyone pump a price to + unlock headroom or crash it to block the agent. `market_valuation(id)` + reports `cost_basis`, a manipulation-resistant `floor_value` (complete + sets `min(yes, no)` plus `min(reserve_yes, reserve_no)` as unclaimed LP; + the settlement value once final), an informational `spot_value`, and + `at_risk = max(0, cost_basis - floor_value)`. Net accounting starts when + the contract is deployed (missing entries read as zero). The treasury's +creator-side claims are split the same way the fees are: `collect_market_fees` +sweeps the **protocol portion** to the treasury, while `agent_claim_lp_fees` +claims the LP portion for markets the treasury created. + +**Price limits.** Size caps do not stop the treasury buying YES at 99% in a +pool that was at 40% a moment ago (a buggy strategy, a compromised agent key, +a sandwich). A `PricePolicy { max_buy_price_bps, min_sell_price_bps, +max_impact_bps, max_slippage_bps }` (defaults 9500 / 500 / 500 / 200) is +enforced inside every agent trade, using market-core's own `get_price` so the +rounding matches what clients see: + +- buys need the outcome's spot price `<= max_buy_price_bps`, sells need it + `>= min_sell_price_bps`; `agent_create_market` needs `initial_yes_bps` + within `[min_sell, max_buy]`; +- `min_shares_out` is raised to the same-transaction `quote_buy` minus + `max_slippage_bps` (never below 1), and `max_shares_in` is capped at + `quote_sell` plus `max_slippage_bps` (rounded up); +- after the trade, `|p_after - p_before| <= max_impact_bps`. + +Because the quote runs against the same pool state as the trade, the quote +floor only protects the agent's own intent; the band is what stops a +front-runner (pushing the price out of band fails the trade), and the impact +limit bounds how far any single trade moves the pool. Large trades in thin +pools are rejected by the impact limit, so strategies must split them; +`max_trade` and `max_impact_bps` interact. market-core's `SlippageExceeded` +is remapped to the treasury's own `SlippageExceeded = 27`; other market-core +errors are re-raised with market-core's codes, which overlap the treasury's +numerically. The checks add three cross-contract view calls per trade: a +1 USDC `agent_buy` against a real market-core measured ~3.5M instructions in +`price_checks_cost_estimate_recorded`. + +**Timelocked configuration.** The global caps (`GlobalConfig`: collateral, +market_core, `max_trade`, `max_market`, `max_daily`, `max_net_exposure`), the +price policy and agent policies change through propose/execute with +asymmetric rules: anything that only tightens (lower caps, a narrower band, +fewer roles) applies immediately; anything that loosens (any raised cap, a +new or widened agent, a changed collateral or market-core) waits +`config_delay` (at least one day, set at construction, can only grow via +`set_config_delay`) and is announced first by `ConfigProposed` / +`AgentPolicyProposed` / `PricePolicyProposed`. A proposal that lowers one +value and raises another is a loosening as a whole; split it to apply the +tightening at once. Execution (`execute_config`, `execute_agent`, +`execute_price_policy`) is permissionless once due, so it never depends on the +admin; `cancel_*` is admin-only. A tightening applied while a loosening is +pending leaves that proposal and its timer as they are. A collateral switch +is only allowed for an empty treasury (no balance, open markets or queued +withdrawals). A market-core switch leaves positions in the old core where they +are: the old core is recorded as legacy, `legacy_redeem` / +`legacy_claim_pool_remainder` recover them, and exposure for any later core +is kept under keys namespaced by core address (the original core keeps the +old `Market(id)` / `Net(id)` keys) so restarted market ids cannot collide. +The new core still needs its own `propose_treasury` handshake for fee sweeps. +This bounds +what a compromised admin can unlock *for the agents*; it is not a custody +control (see "Vault" and SECURITY.md). + +**Vault.** Deposits mint internal shares against a conservative NAV and +withdrawals burn them; there is no admin `withdraw`. `nav() = idle + +Σ floor(open markets) - queue_reserved`, where an open market's floor is its +complete sets `min(yes, no)` plus `min(reserve_yes, reserve_no)` for an +unclaimed LP role, and a final market counts its exact settlement value. The +directional part of a position is valued at zero, so trading against a pool +cannot raise NAV. The open-market index walked by `nav()` is bounded at +`MAX_OPEN_MARKETS = 12` (two market-core reads each; 16 already used ~40 MB +of the 40 MiB per-transaction memory limit); a buy or creation in a 13th +market fails with `TooManyOpenMarkets`, and markets leave the index once +redeemed and claimed. Share math rounds toward the vault and uses a virtual +offset (1,000 shares / 1 stroop) plus dead shares on the first mint against +donation-based share inflation; deposits must be at least `MIN_DEPOSIT` +(10 USDC). `request_withdraw` prices the shares at once, pays what free idle +collateral allows and queues the remainder as a FIFO ticket; +`claim_withdraw(ticket)` (permissionless, pays the owner) settles the head +ticket as capital returns, and agents can never spend `queue_reserved()`. +While paused, `emergency_withdraw` pays shareholders their pro-rata part of +free idle collateral without touching market-core. See +[ADR 0005](adr/0005-treasury-vault.md). + +**Migration to a successor treasury.** The treasury has no upgrade path, so +redeploying it (a bug fix, or anything the timelocked setters above do not +cover) means deploying a new contract. `set_successor(successor)` +(admin) records where value may go and emits `SuccessorSet`; then +`migrate_market(market_id)` (admin, **not** agent) moves the treasury's +YES/NO position and, if it is still the LP, its LP ownership for one market +to the successor — market by market, so the footprint stays bounded — and +emits `MarketMigrated`. The auth model: + +- The agent has no path: both migration entrypoints are `require_admin`. +- The destination is fixed to the configured `Successor` — `migrate_market` + takes no destination argument, so even a compromised agent key cannot + redirect value. It is still an admin power over shareholders' capital: + migrated positions leave this treasury's NAV without compensation, so a + compromised admin could move them to a successor it controls. The + successor is visible on-chain via `SuccessorSet` before any + `migrate_market`, and SECURITY.md lists this as a known admin power. +- The treasury's calls to market-core's `transfer_position` / `transfer_lp` + are *direct* calls, so market-core's `require_auth` on the treasury's own + address is satisfied implicitly by the invoker rule — no + `authorize_as_current_contract` entry is needed (unlike the nested token + call in `authorize_token_pull`). This is proven by the + `pitfall_migrate_market_needs_only_admin_auth` test, which permits only + the admin's signature and no sub-invocations. + +A migrated market's `MarketExposure` on the successor starts at zero and the +old treasury's entry is closed (`open = false`, amount preserved), so the +successor's caps apply to its own future activity — acceptable because the +cap is a per-deployment risk bound, not a market-level accounting value. +Successor-side acceptance (`accept_migration`) is deliberately not +implemented: it would record provenance only, and the events plus the +successor's own exposure records are enough for an off-chain dashboard +([wave-issue 08](wave-issues/08-treasury-exposure-dashboard.md)). + +- `buy` locks `collateral_in = net + fee`, because `net` mints sets and + `fee` accrues to the protocol/LP shares. The fee remains inside + `locked` until `sweep_fees` / `claim_lp_fees` / `claim_pool_remainder` + subtract it — it is never double-counted. +- `sell` burns gross sets and pays out `collateral_out`; the fee + `gross - out` stays in the market's fee accrual, and the locked delta is + only the cash actually leaving. +- `claim_pool_remainder` zeroes the reserves and subtracts the payout + from `locked`. After this claim, `sets_minted`+`$fees_accrued` is no + longer the correct figure for what the market still owes; the + solvency report uses `locked` alone in that state. +- `sweep_fees` subtracts the swept amount from `locked`. +- Any negative result returns `Error::Overflow` (with a `debug_assert` + in debug builds). + +**Permissionless settlement & exposure release (#45).** Settle market capital +without depending on hot agent keys: `settle_market(caller, market_id)` is +permissionless and idempotent. It redeems the treasury's outcome-share position if +any, claims the LP remainder if the treasury created the market, marks market exposure +closed (`open = false`), and records realized proceeds under `Realized(market_id)`. +Calls to `market-core` use generated `try_` client methods so expected core errors +(`NothingToRedeem`, `AlreadyClaimed`, `NotFinal`) map cleanly to 0 or distinct treasury +errors without unhandled transaction aborts. Settlement operates even when the treasury +is paused (stopping trading, not fund recovery). + +**Realized PnL & auto-pause on drawdown (#46).** Cumulative losses across markets +are bounded by an automated drawdown guard. The treasury tracks collateral cost +(buys and market seeds) and proceeds (sells, redemptions, LP remainders) per market +(`MarketPnl`). PnL is realized once a market is final and all positions/LP claims are settled +(or via permissionless `realize(market_id)` for pre-close exits). A rolling window of daily +buckets advances lazily, summing net realized PnL across `window_days`. If `window_pnl < -max_drawdown`, +the contract trips into drawdown pause (`DrawdownTripped` instance flag, emitting `DrawdownPause`). +In this mode, buys and creations are blocked, but `agent_sell` remains open (reduce-only) to avoid +trapping positions. Resuming requires admin `acknowledge_drawdown()` before unpausing. Third parties +triggering settlements cannot manipulate loss magnitude, only realization timing. Protocol fees and +external donations are strictly excluded from PnL accounting. + +**Market-creation risk controls (#47).** Market seeds are decoupled from trade caps +via a dedicated `CreationPolicy` (max seed, rolling creation count limit, close horizon +bounds, allowed category bitmask). Stored in instance storage with bounded bucket arrays +(`CREATION_BUCKETS = 24`), creation limits are enforced before any cross-contract calls. +Admin policy updates are tighten-only (`set_creation_policy`), preventing a compromised key +from instantly loosening rules without a redeploy. + +**Blend lending integration & JIT liquidity (#48).** Idle USDC can be supplied to a +configured Blend pool (`set_yield_venue`, `allocate_to_yield`, `recall_from_yield`) up to +`max_allocation` while preserving at least `max_daily` in liquid collateral. Spending entrypoints +(`agent_buy`, `agent_create_market`) use Just-In-Time liquidity (`ensure_liquid`): shortfalls in +liquid reserves trigger an atomic withdrawal from Blend within the same transaction. If pool +utilization prevents withdrawal, the trade reverts cleanly (`YieldWithdrawFailed`, fail-closed). +NAV views (`available_capital`) account for liquid plus supplied capital, alongside `capital_breakdown`. +See [ADR 0006](adr/0006-blend-integration.md). + +The nested-authorization pitfall this design implies, and how it's handled, +is documented at length in `contracts/treasury/src/lib.rs` (see +`authorize_token_pull`) and exercised by +`pitfall_agent_buy_requires_treasury_self_authorization_for_nested_transfer` +in the same file's test module — a test that's been verified to fail +without the fix and pass with it (see the commit history / docs/STATUS.md). + +The global guard is the only check that can be made against the shared +ledger balance: a per-market figure cannot be verified on-chain because +the balance is shared across markets. Donations (anyone sending tokens +directly to the contract) make `balance > TotalLocked`, which is +normal and must not revert. + +#### Treasury cap guarantees + +What the caps actually promise, as checked by +`contracts/integration-tests/tests/treasury_caps_exhaustive` (below), so that +"daily cap" is not over-read. Auth is mocked in that search; wrong-caller +behaviour is covered by each contract's own tests. + +**Guaranteed** (every reachable state of the searched alphabet, I1-I9): + +| | Guarantee | +|---|---| +| I1 per call | A successful `agent_buy` spends at most `max_trade`. A successful `agent_create_market` seeds at most `max_seed` (the creation policy, which may exceed `max_trade`; it is also at most `max_market`). | +| I2 per market | Cumulative agent spend into one market, seed included, is at most `max_market`, for the market's whole life: it is never freed by sells or `close_trade`. `MarketExposure.amount` equals the observed sum of spends. | +| I3 daily | The treasury's reported window (`daily_usage`) never exceeds `max_daily` and equals the spends observed since its reported start. | +| I4 sliding 24h | In **any** interval `[t, t + 86_400)` the agent spends at most `max_daily`. The window is hourly buckets summed over the trade's hour and the 24 hours before it: effectively 24-25h, conservative and never permissive. | +| I5 pause | While the admin has paused, `agent_buy`, `agent_create_market` and `agent_sell` all fail with `Paused`. `close_trade`, `redeem` and `claim_pool_remainder` stay callable: they spend nothing and return capital. (An automatic drawdown pause differs: reduce-only sells stay allowed; not part of this search.) | +| I6 accounting | Treasury token balance = initial - Σ spends + Σ returns (sells, redeems, claims), from the operations' own parameters. | +| I7 sell neutrality | `agent_sell` changes neither the daily window nor any `MarketExposure`. | +| I8 | Net exposure stays within `max_net_exposure`. | +| I9 completeness | An operation within every observable cap succeeds, so a cap is not silently stricter than documented (this is what catches an off-by-one such as `>=` for `>` on `max_market`). | +| Atomicity | A failed call changes no observed quantity (balances, window, exposures, net exposure). | + +**Not guaranteed:** + +- *Admin actions are not agent spending.* `withdraw`, `emergency_withdraw`, + config changes after their timelock, and the market-core admin swapping the + resolver or treasury role all bypass these caps by design. +- *`max_daily` is not a calendar-day cap.* It is a trailing 24-25h cap, so the + agent can be refused a spend that is a few minutes over 24h after a previous + one. It is also not a cap on losses by itself: an agent may spend `max_daily` + every 25 hours, and per market until `max_market`. +- *History: this used to be 2x.* The original fixed window reset to `now` at + the first call after 24h, so an agent could spend `max_daily` just before a + reset and `max_daily` just after (up to `2 * max_daily` in a short span). The + sliding window fixed that; the explorer was written expecting to *report* + that violation (I4) and now finds none. Mutating `BUCKETS` from 25 to 24 + brings I4 back with a depth-5 counterexample (5U spent in one 24h span + against `max_daily = 4U`), pinned by the treasury unit test + `explorer_i4_sequence_stays_within_max_daily`. +- *Prices and breakers are out of scope.* The search lifts the price policy; + slippage, price band and impact are tested separately. +- *The search is bounded.* "Holds up to depth N over this alphabet", not a + proof for all sequences, caps or market counts. + +##### The search + +```bash +cargo test -p integration-tests treasury_caps_exhaustive -- --nocapture # depth 6 +TREASURY_SEARCH_DEPTH=8 cargo test -p integration-tests treasury_caps_exhaustive -- --nocapture +TREASURY_SEARCH_ALPHABET=full ... # the complete alphabet +TREASURY_SEARCH_MARKET_CORE=wasm ... # market-core in the Soroban VM +``` + +Operations: `agent_buy` and `agent_sell` on each market, `agent_create_market`, +`close_trade`, clock advances `{1, 43_200, 86_399, 86_400}` s, and admin +`Pause`/`Unpause`, over two pre-existing third-party markets (and up to two +treasury-created ones).

Failures are never classified by error code alone +(a market-core error is re-raised under its own code, and e.g. `MarketClosed` +is 9, the same as the treasury's `InsufficientBalance`). + +- *Order:* breadth-first, so the first violation is a shortest one, printed as + a replayable test body (`f.buy(0, 2 * U); f.advance(86_399); ...`). +- *Memoization:* a canonical key of the behaviourally relevant state: pause + flag, `now % 3600`, the window's buckets newest-first, the spends of the last + 25h by exact age (the history I4 needs), and per market the exposure, open + flag, treasury share count (bucketed) and closed status. Absolute time is + never in the key, and market reserves deliberately are not (they only decide + whether a trade clears market-core, which the share bucket and closed status + cover); including them makes almost every trade ordering a distinct state. +- *Symmetry:* the two pre-existing markets are interchangeable, so market + summaries are sorted in the key, and an operation on a market whose + summary equals a lower-indexed one is skipped. +- *Snapshots vs replay:* each child state is built either by re-running the + path on a fresh world or by restoring an `Env` snapshot of the parent. + Measured (`cargo test -p integration-tests -- --ignored branching_benchmark + --nocapture`, depth 3): replay 7.4 ms/operation, snapshot 3.7 ms/operation, + and the gap grows with depth because replay is O(depth). Both produce + identical state counts; snapshot restore is used. Two non-obvious details: + `Env::from_snapshot` always writes a test-snapshot JSON file when the `Env` + is dropped on a *named* thread (every test thread is), which cost 7 minutes + for 4,000 operations, so the search runs on unnamed threads (the SDK skips + the write then); and native contracts are not part of a snapshot, so they are + re-registered with their constructor turned into a no-op. +- *Market-core:* the deep search registers `market-core` natively for speed; + `market_core_wasm_matches_native` runs depth 4 on the vendored wasm and + asserts exactly the same states, operations and growth. The treasury is also + native (the wasm artifact does not exist at `cargo test` time), i.e. the real + contract code, not a mock. +- *Alphabet:* the default `lean` alphabet drops 1s clock ticks, `close_trade`, + seeds that always fail the seed cap, sells with no shares and a second + treasury-created market; `full` is the complete one and is for deeper runs + (below). +- *Results* (depth 6, lean, native market-core, 8 threads): 9,940 abstract + states, 115,208 operations, 103 s; no violation. `full`, depth 5: 7,653 + states, 130,218 operations, 98 s (measured). The work grows about 3.5-5x per + depth, so `full` at depth 6 and `lean` at depth 8 are estimated at roughly + 8 and 20 minutes on 8 cores (not measured). The nightly workflow + (`.github/workflows/treasury-search-nightly.yml`) runs a deeper search and + keeps its output as an artifact; hosted runners have fewer cores, so expect + a few times longer there. +- *Teeth* (recorded in the PR): `new_market > max_market` mutated to `>=` is + reported at depth 2 as an I9 failure (`1U + 2U = 3U` is exactly the cap and + must be allowed); deleting `assert_not_paused` from `agent_buy` is reported + at depth 2 as an I5 violation (`f.pause(true); f.buy(0, 1 * U);`); the + 24-bucket window above is reported as I4 at depth 5. + +### reasoning-registry + +**Views.** `solvency_report(market_id)` returns a `SolvencyReport` +with the market's locked collateral, fees accrued, sets minted, and + outstanding-claims upper bound (`sets_minted + fees_accrued` while +open or unclaimed, derived from `locked` alone after the LP claim), +plus `lp_claimed`. `global_solvency()` returns `(token.balance(contract), +TotalLocked)`. The per-market figure is an audit aid, not an enforced +check; the global guard is the enforced one. + +**Misbehaving collateral.** A fee-on-transfer or rebasing SEP-41 token, a +Classic asset whose issuer has `AUTH_CLAWBACK_ENABLED` and claws back +from the contract, or a buggy custom collateral each make the contract hold +less than it owes. The balance-delta checks reject fee-on-transfer +collateral at the first inflow (`CollateralMismatch`). If the issuer claws +back between transactions, the next outbound transfer trips `Insolvent`. +That freezes payouts globally — intentional fail-safe behaviour, so the +shortfall is visible instead of silently draining other markets. + +The contract has no upgrade path today (see `scripts/deploy-testnet.sh`), so +this is a new-deployment-only change: a redeployed market-core starts from +`TotalLocked = 0`. There is deliberately no admin setter to backfill the +counter for pre-existing markets, because that would be an obvious +privileged backdoor. + +**Fee split and recipient snapshot.** `create_market` snapshots a +`FeeTerms { recipient, protocol_share_bps }` side entry per market, so +`set_treasury` / `set_protocol_fee_share_bps` only affect markets created +after them. Each trade's fee is split once at accrual time +(`math::split_fee`, protocol shares round up so `protocol + lp == fee` +exactly): the protocol portion accumulates in `Market.fees_accrued` and is +swept to the snapshotted recipient by the permissionless `sweep_fees`(old `FeesSwept` event kept for indexers, plus `FeesSweptTo`); the creator +portion accumulates in a `LpFees(market_id)` side entry, claimable any time +(before finality too) via `claim_lp_fees`, and also drained by +`claim_pool_remainder`. Markets created before this change have no +`FeeTerms` entry and fall back to the old behavior: recipient = whatever +`DataKey::Treasury` Holds at sweep time, `protocol_share_bps = 10_000` — +fully backward compatible, no migration transaction needed. The separate +LP balance (rather than adding fees to the reserves) is deliberate: it does +not move `k` or the price and maps directly onto the per-LP fee accumulator +of the future multi-LP design ([wave-issue 02](wave-issues/02-multi-lp-liquidity.md)). + +#### Agent Lifecycle and Trace Annotations (#56) + +The reasoning registry models an explicit lifecycle for agents and traces: +- **Agent lifecycle**: Agents hold `AgentRecord { status: AgentStatus, registered_at: u64 }`. + - `Active`: Registered agent permitted to publish traces. + - `Retired(at)`: Agent gracefully retired by admin (`retire_agent`) or the agent itself (`retire_self`). Retired agents cannot publish new traces, but their existing traces remain valid. Admin may call `reactivate_agent` to return a retired agent to `Active`. + - `Revoked(effective_from, reason)`: Agent revoked by admin (`revoke_agent`) due to compromise or malfeasance. Revocations cannot be reversed or reactivated, preventing history laundering. +- **Trace flagging**: The admin can annotate suspect traces via `flag_trace(trace_id, reason)` and `unflag_trace(trace_id, reason)`. Flags are annotations appended to a bounded history (max 16 entries) and never modify or erase the underlying trace data. +- **Trace verdict**: `trace_verdict(trace_id, received_hash)` evaluates validity in strict precedence: + 1. Not found -> `Err(TraceNotFound)` + 2. Hash differs -> `TraceVerdict::HashMismatch` + 3. Active flag -> `TraceVerdict::Flagged(reason)` + 4. Agent revoked with `trace.published_at >= effective_from` -> `TraceVerdict::AgentRevokedAfter(effective_from)` + 5. Otherwise -> `TraceVerdict::Valid` +- **Semantic tightening of `verify_trace`**: `verify_trace` returns `true` only if `trace_verdict` evaluates to `TraceVerdict::Valid`. Clients wishing to perform bare hash comparison without status checks can query `get_trace`. + +#### Trace Action Validation and Market Reference Integrity (#55) + +Traces reference concrete market actions validated against `market-core`: +- **Canonical Action Vocabulary**: `TraceAction` replaces free-form strings: + | Action | Target Market | Description | + | :--- | :--- | :--- | + | `CreateMarket` | Issued `market_id` | Creation of a new market on-chain | + | `ProposeMarket` | `NO_MARKET` (`u64::MAX`) | Off-chain market proposal prior to creation | + | `Buy` | Issued `market_id` | Purchase of YES or NO shares | + | `Sell` | Issued `market_id` | Sale of YES or NO shares | + | `Skip` | Issued `market_id` | Evaluated market but took no trade action | + | `Redeem` | Issued `market_id` | Redemption of winning or voided shares | + | `ClaimRemainder` | Issued `market_id` | LP reclamation of unredeemed collateral pool | + | `Resolve` | Issued `market_id` | Resolver or oracle resolution attestation | + | `Other(Symbol)` | Issued `market_id` or `NO_MARKET` | Forward-compatible custom action; cannot shadow canonical action names | +- **Market Reference Validation**: + - `market_core.market_count()` is checked via cross-contract read. + - A referenced `market_id` must satisfy `market_id < market_count()`. + - `ProposeMarket` requires `NO_MARKET` (`u64::MAX`), returning `Error::ProposalMustUseNoMarket` if given an actual `market_id`. + - Canonical actions (`Buy`, `Sell`, etc.) reject `NO_MARKET` with `Error::MarketRequired`. + - View function calls to `market_count()` remain functional even when `market-core` is paused. + +#### Merkle-Batched Trace Anchoring (#54) + +To slash per-decision publishing costs for high-frequency trading or extensive skip auditing: +- **Off-chain Batching**: Agents collect up to 4,096 trace hashes off-chain, compute a Merkle tree, and anchor the 32-byte root and manifest CID on-chain via `publish_trace_batch(agent, root, leaf_count, manifest_cid)`. +- **Cryptographic Specifications**: + - **Second-Preimage Resistance**: RFC 6962 domain separation prefixes: leaves hash with `0x00 || trace_hash`, inner nodes hash with `0x01 || left || right`. + - **Odd Node Promotion**: An odd child at any tree layer is promoted unchanged to the next level without duplicating or hashing with itself. When verifying an odd node, no proof element is consumed for that layer. + - **Bounded Proof Length**: With `MAX_LEAVES = 4096`, proof length is strictly bounded to `MAX_PROOF_LEN = 12`. Any proof exceeding 12 elements is rejected with `Error::InvalidProof`. +- **Verification**: `verify_trace_inclusion(batch_id, trace_hash, index, proof)` and `compute_merkle_root(leaf_count, trace_hash, index, proof)` enable on-chain and off-chain (x402 verifier, agents) verification against canonical golden test vectors (`docs/vectors/merkle-v1.json`). + +#### Ed25519-Signed Trace Attestations (#53) + +To enable independent verification of trace authenticity without trusting the registry admin: +- **Dedicated Agent Signing Keys**: Agents bind dedicated Ed25519 public keys (`BytesN<32>`) to their on-chain identity via `add_signing_key(agent, public_key, proof_sig)`. + - **Proof of Possession**: `proof_sig` proves ownership of the secret key by signing `"oracledesk-agent-key-v1" || network_id || registry_id || agent_xdr || public_key`. + - **Key Binding & Lifecycle**: Keys are uniquely bound to agents (at most 4 active keys per agent) with full rotation history (`SigningKeyRecord { public_key, added_at, retired_at }`) tracked via `retire_signing_key`. +- **Domain-Separated Trace Attestation**: `publish_trace_signed(agent, market_id, action, trace_hash, ipfs_cid, signing_key, signature)`: + - Message format: `"oracledesk-trace-v1" || network_id || registry_id || agent_xdr || market_id_be || action_tag || trace_hash`. + - On-chain verification via `env.crypto().ed25519_verify`. + - The attestation signature is stored under `TraceSignature(trace_id)` and queriable via `get_trace_signature` and `verify_trace_signature`. +- **Zero-Trust Offline Verification**: Any consumer holding the trace JSON and public key (e.g., an x402 subscriber or frontend auditor) can verify authenticity offline without RPC access or reliance on contract admin honesty. + +**Known limitation**: Soroban RPC only retains a short window of historical +events. An indexer (Soroban events → Postgres, replayable) is required for +any UI that wants to list traces/trades older than that window — this is +one of the seeded `docs/wave-issues/`. + +## Storage TTL policy + +Soroban archives persistent/instance entries once their TTL runs out, and an +archived entry cannot be read or written until it is restored. Every contract +carries an identical `src/ttl.rs` (duplicated because contract crates cannot +depend on each other — [ADR 0002](adr/0002-cross-contract-calls.md)) with the +shared policy: + +- Per-market entries (`Market`, `Position`, resolver configs, treasury + exposure) are extended to `close_time` plus a 90-day settlement horizon, + clamped to the network's `max_ttl()`. The threshold is half the target, so + a frequently touched entry is only rewritten when its remaining TTL halves. +- Instance TTL is extended by every entrypoint that reads instance storage + (30-day target, 7-day threshold); pure views over persistent entries stay + read-only so indexer simulations keep read-only footprints. +- The registry additionally refreshes an agent's registration on every + successful `publish_trace`. +- The market-core `Settle` entry (outstanding shares, redemption deadline) is + kept to the long-lived target — 365 days, clamped to `max_ttl()`. A market + whose redemption deadline is more than one network-max TTL away can archive + before it is finalized and needs touches or a restore first; + `finalize_market` works after a restore, and the deadline is computed from + on-chain state (`finalized_at + horizon_secs`), so a late finalization is + still exact. +- The market-core `Oracle` entry and every written `Obs` slot are extended to + the same close-time-aware target as the market's other entries. Unwritten + ring slots are never extended and the read path skips missing slots, so a + half-used ring costs nothing and never fails a read. +- Markets whose `close_time` is further out than `max_ttl` cannot be kept + alive by a single bump and need periodic touches or the keeper described in + [`docs/wave-issues/14-storage-ttl-keeper.md`](wave-issues/14-storage-ttl-keeper.md), + which also covers TTL monitoring and the rent cost model. +### router + +A stateless address book (`RouterConfig { market_core, resolver, +reasoning_registry }`) plus atomic multi-step entrypoints, so a client cannot +half-apply a flow or point it at a hostile resolver (ADR 0009): +`create_and_reveal_signers` / `create_and_reveal_price` (create the market and +reveal its rule in one transaction; the commitment is computed locally from +the spec), `reveal_spec` (the deferred commit-now/reveal-later path), and +`buy_and_publish_trace` (buy through market-core and publish the reasoning +trace together, so a trade cannot drop its trace). It holds no funds and has +no admin. + +### Governance: wiring, admin transfer, timelock + +- **Authenticated wiring (ADR 0006).** `market-core` no longer lets the admin + set the resolver/treasury directly. It `propose_resolver` / + `propose_treasury`; the target must then prove, by calling back + `market_core()`, that it is configured for this market-core before it takes + the role. Every change emits `ResolverProposed`/`ResolverChanged` (and the + treasury equivalents). Deploys are deterministic (`--salt`), so the real + addresses are known before `market-core`'s constructor runs and there is no + placeholder window. +- **Two-step admin transfer (ADR 0007).** All four core contracts (and the + timelock) expose `propose_admin`/`accept_admin`/`cancel_admin_transfer` with + a seven-day expiry. The new admin must accept, so a proposal to an address + the operator does not control never lands; `new_admin` may be a classic + multisig account, a smart-account multisig, or the timelock. +- **Timelock (ADR 0008).** `contracts/timelock` separates the proposer, + canceller, executor and emergency roles and imposes a delay + (`MIN_DELAY = 1 day`) between `schedule` and `execute`, with a seven-day + execution grace and a `cancel` veto. `emergency` bypasses the delay for + `set_paused(true)` / `cancel_proposal` only. Pointing the core contracts' + admin at the timelock (deploy with `USE_TIMELOCK=1`, or migrate with + `scripts/wire-timelock.sh`) removes any single key's ability to change a + live market instantly. + +## Off-chain pieces + +- **x402/**: an Express service selling reasoning traces for ~$0.01 via + `@x402/*`'s exact-payment Stellar scheme.

The trader always quotes + (`quote_buy`) immediately before submitting and derives non-zero + `min_shares_out` / `limit_price_bps` bounds plus a deadline from it. +- **packages/bindings/**: generated TypeScript clients (`scripts/gen-bindings.sh`). + +### Trader sizing + +The trader's optional sized path computes an impact limit by binary-searching +the integer `calcBuy` curve, so it respects the contract's fee and +pool-favoring rounding rather than a floating-point reserve approximation. +It shrinks the fair-value probability by `FAIR_UNCERTAINTY_BPS`, maximizes +expected binary-settlement log wealth with existing YES/NO holdings, and +applies the rational `KELLY_FRACTION` (default 0.25). The result is further +bounded by `TRADE_SIZE_STROOPS`, treasury market/daily/capital headroom and +the market's `MAX_SETS` capacity. A report containing the inputs, intermediate +limits and binding constraint is included in the reasoning trace. `SLIPPAGE_BPS` +sets the minimum share output from the exact integer quote, while the trader +also re-quotes immediately before submission and applies a deadline. + +The limit protects the estimated post-trade marginal price from crossing +`effective fair value - SIZING_BUFFER_BPS`; it cannot guarantee a fill if +another transaction changes the pool between the snapshot and execution. +**Trade bounds and circuit breakers.** Two layers of protection beyond the +share-count slippage parameters: + +- *Deadline + limit price* (#12): `buy_v2` / `sell_v2` take a + `deadline` (ledger **timestamp**, unix seconds) checked before anything + else, and a `limit_price_bps` bounding the **average execution price** + (`collateral_in / shares_out` for buys, `collateral_out / shares_in` for + sells, fee included, compared by cross-multiplication). `0` means "no + limit" for buys; for sells it is trivially satisfied and buys no + protection. The original `buy` / `sell` remain as thin wrappers for + backward compatibility (same body, no bounds). +- *Per-market breakers* (#10): `BreakerConfig { max_impact_bps, band_bps }` + is snapshotted per market from an admin default (`set_default_breaker`, + which rejects `band_bps < max_impact_bps` because that makes one trade + cover the whole band). `max_impact_bps` bounds a single trade's + |post − pre| YES-price move (`>` — a trade moving exactly the cap + passes); `band_bps` bounds |post − ledger-open price|, with the reference + stored in short-TTL **temporary** storage keyed by ledger sequence, so it + resets by itself every ledger. 0 disables either check; legacy markets + have no config and are unaffected. Breaker trips revert with + `PriceImpactTooHigh` / `PriceBandExceeded` and — because Soroban rolls + back an invocation's events on `Err` — emit **no** event (the error codes + and the `would_trip`` / `breaker_config` / `breaker_state` views are the + observability path; see the comment on `check_breakers`). + + *Worst-case lock cost.* The band cannot be ratcheted: the reference is + the ledger-open price, so an attacker who pushes the price to the band + edge only blocks further trades for the rest of that ledger (~5 s) — + and pays the trading fee plus price impact to do it, which are both + retained by the pool. + +**Resolution and payouts.** `resolve(market_id, outcome)` sets the +final outcome once. `redeem` pays `payout` for a winning position and +burns it; `lp_claimed` gates `claim_pool_remainder`, which pays the +creator the residual value of the reserves and zeroes them. Both payouts + are subject to the checked transfer and global solvency guard. + +### IPFS trace storage + +In live mode the agents store traces with `IpfsTraceStore` +(`agents/core/ipfs-store.ts`; selected by `TRACE_STORE`, see +`agents/core/trace-store-factory.ts`). The CID that goes on-chain in +`publish_trace(..., ipfs_cid)` is permanent, because `Trace` entries have no +update path. So the agent computes the CID itself and does not trust any +pinning provider to name the content: + +- **Raw CIDv1.** The CID is a CIDv1 with the `raw` codec (`0x55`) and a + sha2-256 multihash over the exact UTF-8 bytes `buildTrace` hashed + (base32 lowercase, `bafkrei…`, 59 characters). Its multihash digest is + therefore *equal to* `trace_hash`. A default `ipfs add` (dag-pb/UnixFS, + chunked) would hash a protobuf wrapper instead and break that property, + so kubo is called with `cid-version=1&raw-leaves=true&hash=sha2-256` and a + 1 MiB chunker, and traces are limited to one 1 MiB block. +- **Providers are verified, not trusted.** Any provider that reports a CID + different from the local one (compared by value with `CID.equals`, not by + string) fails the whole `put`. Pins go to a kubo RPC node and optionally an + IPFS Pinning Service API (`POST /pins`, polled until `pinned`). Each + provider is retried with jittered backoff, and at least `IPFS_MIN_PINS` + must *confirm* the pin. Queued pins count only with `IPFS_ACCEPT_QUEUED=1`. +- **Retrievability is checked.** Before `put` resolves, the agent GETs + `${IPFS_GATEWAY_URL}/` (the gateway x402 also reads), following + redirects, with a byte cap and a timeout, and re-checks `sha256(body)`. + The trade or market creation is only submitted after this succeeds. If + pinning fails, the action is skipped and logged. +- The market-maker also pins a small metadata document (question, category, + close time, trace hash and CID) and sets the market's `meta_uri` to + `ipfs://`. `local://` URIs remain only in dry-run, or in live mode with + `ALLOW_LOCAL_TRACE_STORE=1`. + +**Verifying without fetching.** A buyer holding `(trace_hash, ipfs_cid)` from +the registry can decode the CID: version 1, codec `0x55`, multihash code +`0x12` (sha2-256), length 32. The 32 digest bytes must equal `trace_hash`. +With `multiformats`: +`Buffer.from(CID.parse(cid).multihash.digest).toString("hex") === trace_hash`. +After fetching, `sha256(body) === trace_hash`, as `x402/trace-verification.ts` +checks, proves the bytes are the ones the agent committed to. + +### Event triggers (agents) vs. the event indexer + +`agents/core/events/` (#105) lets agents react to contract events instead +of waiting for their next scheduled run. It is a **trigger system, not an +indexer**, and the two must not be confused: + +| | Event triggers (`agents/core/events`) | Event indexer (`docs/wave-issues/06-event-indexer.md`) | +| --- | --- | --- | +| Purpose | Wake an agent when something it cares about happens | Durable, queryable history for UIs and analytics | +| Storage | One checkpoint per network and contract set: `{cursor, lastLedger}` plus recently processed event ids, in `EVENTS_STATE_DIR` | Every event, in Postgres | +| History | None. Starts at the latest ledger; never replays | Replayable from any ledger it has stored | +| Retention gap | Detected; triggers a full state resync from chain reads | Is the thing it exists to cover | +| Source of truth | Chain state, re-read before every action | Its own tables | + +Flow: `EventSubscriber` polls `getEvents` (cursor pagination, filters +checked against the RPC's limits, failed contract calls dropped) and hands +each page to the `Dispatcher`. Events are decoded with the binding specs +(`decode.ts`, via the SDK's `Spec.parseEvent`) into a typed +`OracleDeskEvent`, with an `Unknown` variant for anything else. + +- **At-least-once delivery.** A page's checkpoint is written only after + every handler finished (or the event was dead-lettered). A crash in + between redelivers the page, so handlers are idempotent and an LRU of + processed ids, saved with the checkpoint, drops repeats. +- **Ordering.** One market's events run in order; different markets run + concurrently up to `EVENTS_CONCURRENCY`. +- **Failures.** A handler is retried with exponential backoff up to + `EVENTS_MAX_ATTEMPTS`, then the event goes to + `/dead-letter.jsonl` and the page moves on. +- **Idle polls** still advance `lastLedger`, so a quiet stretch is not + mistaken for a retention gap. + +Handlers (`handlers.ts`): `TradeReevaluate` queues a market for the trader +after a trade of at least `EVENTS_TRADE_THRESHOLD` stroops (re-reading the +market first); `ProposalWatch` alerts on a `ResolutionProposed` where the +treasury holds a position and the resolver still reports the proposal as +standing (cancellations emit no event), with the dispute deadline computed +from the proposal's ledger timestamp; `FinalityTracker` marks markets final +on `MarketResolved`, `ResolutionFinalized` or `PriceResolution`; and the +resync handler re-evaluates every tradable market after a gap. + +`npm run trader -- --follow` runs this loop (`runtime/follow.ts`); without +`--follow` the trader behaves exactly as before. + +### Cross-market arbitrage (agents, #108) + +Independent FPMM pools can price related markets inconsistently. With +`ARB_ENABLED=1` the trader runs an `arbitrage` task +(`runtime/tasks/arbitrage.ts`) over the relations in `ARB_RELATIONS_FILE`: + +```json +{ "relations": [ { "id": "btc-100k-implies-90k", "type": "implies", "a": 12, "b": 7, + "resolution": { "a": { "mechanism": "price", "source": "reflector:BTC/USD" }, + "b": { "mechanism": "price", "source": "reflector:BTC/USD" } }, + "voidCorrelation": "joint", "maxCloseSkewSecs": 0 } ] } +``` + +- **Relations** (`core/strategies/arbitrage.ts`): `implies` (P(A) <= P(B)), + `complement` (P(A) + P(B) = 1) and `exclusive` (P(A) + P(B) <= 1). A + relation is rejected unless both markets exist and are open, their close + times are within `maxCloseSkewSecs`, and both declare the *same* + resolution mechanism and source; a declared `resolutionHash` must equal + the market's on-chain commitment. The file's canonical sha256 (the graph + hash) is recorded in every trace. +- **Planning**: for each pair of legs, a payoff table over every outcome the + relation allows, plus void scenarios (`joint`: both void together; + `independent`: either may void alone, paying half per share), gives the + worst-case payout, measured on top of existing treasury holdings. Costs + are exact integer FPMM collateral (`collateralForShares`: fees, price + impact and rounding). The share count is found by integer ternary search + and a +/-64 verification scan, inside `max_trade`, remaining `max_market` + headroom, the rolling `max_daily` and `ARB_MAX_NOTIONAL`, and must clear + `ARB_MIN_PROFIT_STROOPS` and `ARB_MIN_PROFIT_BPS`. +- **Risk** (`core/risk.ts`, `checkArbPlan`): treasury caps and existing + exposure; `ARB_MARKET_HEADROOM_BPS` of each market's `max_market` kept free + for later hedges; `ARB_MAX_UNHEDGED_STROOPS` caps the first leg, which is + the exposure left if the second never fills; `ARB_MAX_OPEN_LEGS` and + `ARB_MAX_UNWIND_RETRIES` bound concurrent legs and unwind attempts. +- **Execution** (`core/strategies/arb-executor.ts`): treasury calls are not + atomic, so the legs are sequential. The less liquid market goes first, + re-quoted and bought with `min_shares_out` = the planned shares. The second + market is then re-read; if its cost rose by more than `ARB_MAX_LEG_LOSS` + the first leg is sold back with `agent_sell`, otherwise the second leg is + bought. Every step is journaled before and after submission in + `ARB_JOURNAL_FILE`, and the next run finishes or unwinds any plan a crash + interrupted, settling ambiguous submissions from the treasury's positions. + A trace with the relation, graph hash, snapshots, plan and leg results is + published when a plan completes or is unwound. Dry-run only plans and logs. + +**Residual risks.** Between the legs the treasury holds one side naked: a +fast move can cost up to `ARB_MAX_LEG_LOSS` plus the unwind's price impact, +and if every unwind attempt fails the leg stays open (`ARB_UNHEDGED` is +logged and the plan closes as `unwind-failed`). The relation file is +trusted: a wrong relation produces confident, wrong trades, which is why +compatibility must be declared and is checked against the chain. + +## Known limitations (see docs/STATUS.md for the full, current list) + +- Testnet only; unaudited. +- No indexer yet — anything needing historical events beyond RPC's + retention window has no on-chain-native way to query them. +- Agent-vs-agent liquidity: nothing here stops multiple independent agent + deployments (this repo's or a fork's) from trading against the same + market-core markets; the treasury's caps bound one agent deployment's own + risk, not systemic market behavior. +- MAX_SETS griefing via `split`: an attacker can split up to `MAX_SETS` and + block further `buy` calls (`MarketTooLarge`) at the cost of locking that + much collateral, then merge out risk-free. See the split/merge section + above for why the shared cap is kept. + +### x402 payment preparation, settlement and replay + +One HTTP resource server advertises all effective Stellar networks. Each +facilitator client is scoped to its configured network even if `/supported` +advertises others; API keys never cross those scopes. Startup defaults to +requiring every configured network. `X402_REQUIRE_ALL_NETWORKS=false` probes +and drops unavailable networks, logs structured warnings, and still refuses +startup if none remain. The process awaits initialization before listening. + +For a fresh purchase the trace path is: registry lookup → bounded IPFS fetch → +raw-byte hash verification → JSON parse and response encoding → durable ledger +claim → facilitator verification → durable `settling` transition → settlement → +durable receipt → delivery. No trace bytes are sent before settlement succeeds. +`@x402/*` are pinned to 2.26.0; requirements and scheme capabilities support only +`authorization`. Upfront payloads are rejected. `X402_TRACE_LOAD_TIMEOUT_MS` +(default 10 seconds) bounds the entire preparation phase, including repository +lookup and body reads, and must be less than half `X402_MAX_TIMEOUT_SECONDS` +(default 60). An unpaid unknown trace gets 404 rather than a payment challenge; +this permits enumeration of IDs that are already public in the registry. + +The default ledger is SQLite (`X402_LEDGER_PATH`, default `.x402-ledger.sqlite`), +with WAL, FULL synchronous durability, a unique payment ID and compare-and-set +state updates. `X402_LEDGER=memory` provides the same interface for tests or +explicitly ephemeral sessions. A payment ID hashes the network plus the inner +Stellar transaction hash; fee-bump wrappers and base64 whitespace do not create +new purchases. A stored claim binds it to trace, recipient, network, amount, +asset and requirement settings before verification. Concurrent duplicates get +409 with `Retry-After: 2`; cross-resource or changed-price reuse gets 409. + +States are `verifying → settling → settled → delivered`, with `failed` for +known failures and `indeterminate` for timeouts or interrupted settlement. +The durable transition runs outside SDK hooks because 2.26.0 logs thrown hook +errors and can continue. No ledger write means no settlement attempt. Startup +marks interrupted verifying/settling rows indeterminate; it never retries them. +Operators must inspect/reconcile these against the chain before taking action. +A settlement timeout returns 502 without content. Other SDK failures retain +standard HTTP instructions and payment challenge headers. + +Settled/delivered retries return the original stored body and PAYMENT-RESPONSE +without another facilitator call or gateway fetch. The original raw bytes are +stored and hash-checked again on replay, so a changed registry record cannot +change what was purchased. Retries expire at the original persisted deadline, +bounded by transaction time bounds or maxTimeoutSeconds; expired payments get +402. Finite ledger bounds and Soroban authorization expirations are checked +against a live ledger on both first use and replay, using the corresponding +`STELLAR_TESTNET_RPC_URL` or `STELLAR_MAINNET_RPC_URL`. Failure to obtain that +anchor fails closed. Database/state conflicts are never auto-settled again. + +`GET /admin/payments/:paymentId` requires `Authorization: Bearer X402_ADMIN_TOKEN` +and is disabled if unset. It returns purchase state and transaction/payer fields, +with raw trace bytes, response content and requirement keys redacted. The SQLite +file is permissioned to its owner and git-ignored. Back it up as sensitive +purchase history. This design supports one service process; shared multi-instance locking, refunds and automatic indeterminate reconciliation remain separate work. \ No newline at end of file diff --git a/oracledesk-stellar/docs/auth-matrix.md b/oracledesk-stellar/docs/auth-matrix.md index 25702ce7..d0fa1cb8 100644 --- a/oracledesk-stellar/docs/auth-matrix.md +++ b/oracledesk-stellar/docs/auth-matrix.md @@ -1,88 +1,88 @@ -# Cross-contract authorization matrix - -`contracts/integration-tests` is a test-only crate that imports the **shipping -wasm** for `market-core`, `resolver`, `treasury` and `reasoning-registry` -(`contractimport!` from `contracts/integration-tests/wasm/`) and wires them the -same way the deploy scripts do.

The -contract has moved since that list was written; each was re-checked against the -current code. - -### 1. `cancel_proposal` does not reset votes (confirmed, stranding possible) - -`resolver_cancel.cfg`, trace: `RegisterSigners, Tick, Attest(s1,Yes), -Attest(s2,Yes), Cancel`. Counts survive a cancel, so a *new* signer attesting -the quorum outcome re-proposes instantly (a fresh window; the guardian may -cancel at most twice). But when every signer already backs the quorum outcome -(`N = T`, as in the unit-test fixture) nothing can re-propose it: the signers -cannot attest it again (`AlreadyAttested`), and `finalize_signers` fails with -`NoProposal`. - -**Assessment: design limitation, doc now accurate.** The doc comment ("the next -attestation that brings any outcome to threshold … proposes again") already -describes the behaviour, but it is not obvious that this can dead-end a -market. The way out is intended: `GuardianReason::SignersStalled` after -`SIGNER_GRACE_SECS`, or `expire_market` after the deadline (which is allowed -because no proposal exists). Replayed by -`model_trace_cancel_strands_quorum_until_stalled_void`. - -### 2. "Both outcomes can alternate proposals and delay finalization" (refuted) - -`resolver_both_outcomes.cfg` (N=4, T=2, i.e. `T ≤ N/2`): `ProposalTimestampStable` -holds. Current `record_attestation` only proposes when no proposal is pending -(`may_propose`), so later attestations, including a quorum for the other -outcome, never move `proposed_at`. Replayed by -`model_trace_other_outcome_quorum_does_not_reset_window`. - -The one exception is intended and was found by `resolver_invalid.cfg`: an -**Invalid** quorum displaces a pending Yes/No proposal and restarts the window, -and an Invalid proposal is never displaced (replayed by -`model_trace_invalid_quorum_displaces_yes_and_restarts_window`). Delay is -therefore bounded to one restart. With `T ≤ N/2`, a coalition of `T` dishonest -signers can force a Void instead of a Yes/No (`resolver_live_invalid.cfg`, the -documented "a quorum saying the question is unanswerable outranks an answer"). -That is a property of the m-of-n trust assumption, not a bug. - -### 3. Guardian void before close (refuted) and attest-after-void guard (sufficient) - -`NoResolveBeforeClose` holds. Every `GuardianReason` other than `DisputeUpheld` -requires `now ≥ close_time`, and `DisputeUpheld` needs a proposal, which needs -an attestation, which needs `now ≥ close_time`. After a guardian void, -`attest` fails with `AlreadyFinalized` and `finalize_signers` (which does not -check `ResolutionState` itself) fails inside market-core with `MarketNotOpen`, -so the guard is sufficient. Replayed by `model_trace_no_void_or_attestation_before_close` -and `model_trace_guardian_void_blocks_later_attest_and_finalize`. - -### 4. Admin bypass breaks `ResolvedOutcomeHadThreshold` (confirmed, trust assumption) - -`resolver_bypass.cfg`: `RegisterSigners, Tick, AdminBypass(Yes)`. market-core's -admin can propose and accept another resolver, which resolves without this -resolver's signers voting at all; this resolver stays `SignersPending`. This is -the two-step wiring (ADR 0006, 0007) working as designed: the market-core admin -is trusted. Replayed by `model_trace_admin_bypass_resolves_without_threshold`. - -### Other observations - -- `cancel_proposal` does not check `ResolutionState`, so inside the window it - also works on an already guardian-voided market (it only removes the - proposal and spends one of the two cancels). Harmless; mirrored by the model. -- `finalize_signers` computes `proposed_at + dispute_window` with unchecked - `+` (release builds enable `overflow-checks`, so it traps), while the other - window checks use `saturating_add`. `dispute_window` is only validated - non-zero.

Guard order therefore only decides *which* +error the contract returns (e.g. `attest` checks `AlreadyFinalized` before +`AlreadyAttested`); the model does not distinguish them. market-core's own +guards are folded into the action that calls it (`status = "Open"` for both +`resolve` and `void_market`). + +**Time.** `now` saturates at `D`: every guard compares it to a threshold `≤ D` +(`C`, `C+RG`, `C+OG`, `C+SG`, `D`), so later times are indistinguishable. A +proposal stores `age` (ticks since it was proposed) saturating at `W` instead +of `proposed_at`, since `now < proposed_at + W ⇔ age < W`. This also keeps +liveness checking finite. + +**Not modelled** (deliberately; each is orthogonal to the lifecycle): FPMM +pricing, treasury and tokens, `SignersDisputable` bonds (`Disputed` state), +weighted keys, committee rotation and the hybrid mode's fallback opening, and +`u64` overflow (naturals are used; see Notes). Hybrid, weighted and committee +resolution all end in the same `resolve`/`void_market` calls modelled here. + +**Bounds.** `Signers` is 2–4 model values, `T = 2`, `C = 1`, `W = 1`, +`RG = OG = 2`, `SG = 3`, `D = 6`, `MaxCancels = 2` (the contract's value). +Small constants are enough because behaviour only depends on the *order* of +the thresholds; symmetry over signers is used for the safety configs. + +## Properties + +| Name | Meaning | Kind | +|---|---|---| +| `TypeOK` | well-typed state | invariant | +| `AtMostOnceFinal` | market-core leaves `Open` at most once | invariant | +| `StatusMonotone` | after leaving `Open` the status never changes | action property | +| `VoidMeansNoResolve` | a `Void` market is never `Resolved` | action property | +| `FinalImpliesClosed` | resolver `Finalized`/`Expired` ⇒ market status ≠ `Open` | invariant | +| `ResolvedOutcomeHadThreshold` | a Yes/No result of a signer-mode market had quorum | invariant | +| `NoFinalizeAfterCancelWithoutNewProposal` | a cancelled proposal is never the one finalized | invariant | +| `WindowRespected` | signer finalization only after the dispute window | action property | +| `NoResolveBeforeClose` | nothing resolves or voids before `close_time` (except bypass) | invariant | +| `ProposalTimestampStable` | later attestations never replace a pending proposal except by an Invalid quorum | action property | +| `Liveness` | `<>(status ∈ {Yes, No})` under fairness | temporal | +| `NoStrandedQuorum` | witness: quorum exists but no proposal | invariant (expected to fail) | +| `NoInvalidDisplacement` | witness: Invalid never displaces Yes/No | action property (expected to fail) | + +Liveness assumptions (`LiveSpec`): time passes, the market gets configured, +honest signers (who only ever vote Yes) attest when they can, a ready proposal +is finalized, and the guardian, expiry and bypass are off. + +## Results + +| Config | Expected | Result | Distinct states | Time | +|---|---|---|---|---| +| `resolver.cfg` (N=3, all modes, guardian, expiry) | all hold | **No error** | 40,200 | ~1 s | +| `resolver_both_outcomes.cfg` (N=4, T=2) | `ProposalTimestampStable` holds | **No error** | 100,518 | ~4 s | +| `resolver_live.cfg` (N=3, honest = 2) | `Liveness` holds | **No error** | 360 | < 1 s | +| `resolver_cancel.cfg` (N=T=2) | `NoStrandedQuorum` fails | **violated** (exit 12) | 143 | ~1 s | +| `resolver_invalid.cfg` (N=T=2) | `NoInvalidDisplacement` fails | **violated** (exit 13) | 255 | < 1 s | +| `resolver_bypass.cfg` (N=3) | `ResolvedOutcomeHadThreshold` fails | **violated** (exit 12) | 91 | ~1 s | +| `resolver_live_invalid.cfg` (N=4, honest = 2) | `Liveness` fails | **violated** (exit 13) | 4,966 | ~1 s | + +State counts for the violated configs vary slightly from run to run (TLC stops +at the first violation while several workers are exploring); the verdicts do not. + +The checks have teeth: dropping the window guard from `Finalize`, letting +`Cancel` keep the proposal, dropping the `Open` guard from market-core, or +allowing attestation before close each make one of the properties fail +(mutation-tested while writing the model). + +## Findings + +The issue that asked for this model listed four findings to investigate. The +contract has moved since that list was written; each was re-checked against the +current code. + +### 1. `cancel_proposal` does not reset votes (confirmed, stranding possible) + +`resolver_cancel.cfg`, trace: `RegisterSigners, Tick, Attest(s1,Yes), +Attest(s2,Yes), Cancel`. Counts survive a cancel, so a *new* signer attesting +the quorum outcome re-proposes instantly (a fresh window; the guardian may +cancel at most twice). But when every signer already backs the quorum outcome +(`N = T`, as in the unit-test fixture) nothing can re-propose it: the signers +cannot attest it again (`AlreadyAttested`), and `finalize_signers` fails with +`NoProposal`. + +**Assessment: design limitation, doc now accurate.** The doc comment ("the next +attestation that brings any outcome to threshold … proposes again") already +describes the behaviour, but it is not obvious that this can dead-end a +market. The way out is intended: `GuardianReason::SignersStalled` after +`SIGNER_GRACE_SECS`, or `expire_market` after the deadline (which is allowed +because no proposal exists). Replayed by +`model_trace_cancel_strands_quorum_until_stalled_void`. + +### 2. "Both outcomes can alternate proposals and delay finalization" (refuted) + +`resolver_both_outcomes.cfg` (N=4, T=2, i.e. `T ≤ N/2`): `ProposalTimestampStable` +holds. Current `record_attestation` only proposes when no proposal is pending +(`may_propose`), so later attestations, including a quorum for the other +outcome, never move `proposed_at`. Replayed by +`model_trace_other_outcome_quorum_does_not_reset_window`. + +The one exception is intended and was found by `resolver_invalid.cfg`: an +**Invalid** quorum displaces a pending Yes/No proposal and restarts the window, +and an Invalid proposal is never displaced (replayed by +`model_trace_invalid_quorum_displaces_yes_and_restarts_window`). Delay is +therefore bounded to one restart. With `T ≤ N/2`, a coalition of `T` dishonest +signers can force a Void instead of a Yes/No (`resolver_live_invalid.cfg`, the +documented "a quorum saying the question is unanswerable outranks an answer"). +That is a property of the m-of-n trust assumption, not a bug. + +### 3. Guardian void before close (refuted) and attest-after-void guard (sufficient) + +`NoResolveBeforeClose` holds. Every `GuardianReason` other than `DisputeUpheld` +requires `now ≥ close_time`, and `DisputeUpheld` needs a proposal, which needs +an attestation, which needs `now ≥ close_time`. After a guardian void, +`attest` fails with `AlreadyFinalized` and `finalize_signers` (which does not +check `ResolutionState` itself) fails inside market-core with `MarketNotOpen`, +so the guard is sufficient. Replayed by `model_trace_no_void_or_attestation_before_close` +and `model_trace_guardian_void_blocks_later_attest_and_finalize`. + +### 4. Admin bypass breaks `ResolvedOutcomeHadThreshold` (confirmed, trust assumption) + +`resolver_bypass.cfg`: `RegisterSigners, Tick, AdminBypass(Yes)`. market-core's +admin can propose and accept another resolver, which resolves without this +resolver's signers voting at all; this resolver stays `SignersPending`. This is +the two-step wiring (ADR 0006, 0007) working as designed: the market-core admin +is trusted. Replayed by `model_trace_admin_bypass_resolves_without_threshold`. + +### Other observations + +- `cancel_proposal` does not check `ResolutionState`, so inside the window it + also works on an already guardian-voided market (it only removes the + proposal and spends one of the two cancels). Harmless; mirrored by the model. +- `finalize_signers` computes `proposed_at + dispute_window` with unchecked + `+` (release builds enable `overflow-checks`, so it traps), while the other + window checks use `saturating_add`. `dispute_window` is only validated + non-zero. A huge window therefore means "never finalizable" either way, with + `expire_market` refused (`ResolutionAvailable`) while a quorum proposal + exists, so the guardian is the only exit. The model uses naturals and does + not capture the trap, only the "never" part. +- While writing the bypass test, calling `Resolver::accept_market_core_role` + on a second resolver in the unit-test environment failed with + `Error(Context, InvalidAction)` (market-core's `accept_resolver` calls back + into the same resolver for `market_core()`, which Soroban treats as + re-entry). This was not investigated further and is not covered by the model; + worth checking against the testnet deploy flow in + `scripts/deploy-testnet.sh`. + +No contract behaviour was changed by this work. + +## Conformance tests + +`cargo test -p resolver model_trace_` replays the traces against the real +contracts (two happy paths, plus one test per finding above): + +| Test | Model trace | +|---|---| +| `model_trace_signers_happy_path_yes` | `resolver.cfg` signers path | +| `model_trace_price_happy_path_yes` | `resolver.cfg` price path | +| `model_trace_cancel_strands_quorum_until_stalled_void` | `resolver_cancel.cfg` | +| `model_trace_invalid_quorum_displaces_yes_and_restarts_window` | `resolver_invalid.cfg` | +| `model_trace_other_outcome_quorum_does_not_reset_window` | `resolver_both_outcomes.cfg` | +| `model_trace_no_void_or_attestation_before_close` | `NoResolveBeforeClose` | +| `model_trace_guardian_void_blocks_later_attest_and_finalize` | `resolver.cfg` | +| `model_trace_expire_blocked_by_valid_proposal` | `Expire` guard | +| `model_trace_admin_bypass_resolves_without_threshold` | `resolver_bypass.cfg` | + +## Reproducing a counterexample + +```bash +cd docs/formal +java -cp tla2tools.jar tlc2.TLC -config resolver_cancel.cfg resolver.tla -workers 1 +``` + +`-workers 1` gives the shortest trace (breadth-first). diff --git a/oracledesk-stellar/docs/formal/resolver.cfg b/oracledesk-stellar/docs/formal/resolver.cfg index b78ca42c..cf0c7027 100644 --- a/oracledesk-stellar/docs/formal/resolver.cfg +++ b/oracledesk-stellar/docs/formal/resolver.cfg @@ -1,29 +1,29 @@ -SPECIFICATION Spec -INVARIANTS - TypeOK - AtMostOnceFinal - FinalImpliesClosed - NoFinalizeAfterCancelWithoutNewProposal - NoResolveBeforeClose - ResolvedOutcomeHadThreshold -PROPERTIES - StatusMonotone - VoidMeansNoResolve - WindowRespected -CONSTANTS - Signers = {s1,s2,s3} - T = 2 - C = 1 - W = 1 - RG = 2 - OG = 2 - SG = 3 - D = 6 - MaxCancels = 2 - AllowPrice = TRUE - AllowGuardian = TRUE - AllowExpire = TRUE - AllowBypass = FALSE - Honest = {} -SYMMETRY Perm -CHECK_DEADLOCK FALSE +SPECIFICATION Spec +INVARIANTS + TypeOK + AtMostOnceFinal + FinalImpliesClosed + NoFinalizeAfterCancelWithoutNewProposal + NoResolveBeforeClose + ResolvedOutcomeHadThreshold +PROPERTIES + StatusMonotone + VoidMeansNoResolve + WindowRespected +CONSTANTS + Signers = {s1,s2,s3} + T = 2 + C = 1 + W = 1 + RG = 2 + OG = 2 + SG = 3 + D = 6 + MaxCancels = 2 + AllowPrice = TRUE + AllowGuardian = TRUE + AllowExpire = TRUE + AllowBypass = FALSE + Honest = {} +SYMMETRY Perm +CHECK_DEADLOCK FALSE diff --git a/oracledesk-stellar/docs/formal/resolver.tla b/oracledesk-stellar/docs/formal/resolver.tla index d2a03b91..87319fd5 100644 --- a/oracledesk-stellar/docs/formal/resolver.tla +++ b/oracledesk-stellar/docs/formal/resolver.tla @@ -1,309 +1,309 @@ ----------------------------- MODULE resolver ---------------------------- -(***************************************************************************) -(* Resolution lifecycle of one market: the resolver contract's *) -(* `ResolutionState`, its signer-mode attestations/proposal, price mode, *) -(* the guardian, expiry, and market-core's `MarketStatus`. *) -(* *) -(* Source of truth: contracts/resolver/src/lib.rs (record_attestation, *) -(* cancel_proposal, finalize_signers, guardian_void_market, resolve_price,*) -(* expire_market) and contracts/market-core/src/lib.rs (resolve, *) -(* void_market).

If traders -net-sell the winning outcome the reserve rises and the LP gains. The script -asserts both identities on every reachable state. - -### 3.2 Bound (a): strictly less than the seed - -From L1 and `y, n ≥ 1`: - -``` -loss_YES = y0 − y ≤ y0 − max(1, ⌈k0 / n⌉) < y0 -loss_NO = n0 − n ≤ n0 − max(1, ⌈k0 / y⌉) < n0 -``` - -With `M ≤ MAX_SETS` we also have `y ≤ MAX_SETS`, so a tighter, parameter-only -bound is `loss_NO ≤ n0 − max(1, ⌈k0 / MAX_SETS⌉)`. Since `max(y0, n0) = S` (the -likelier outcome's reserve equals the seed), the **worst case over outcomes is -`S − 1` stroops (infimum)**: the LP can lose essentially its entire seed if -the *unlikely* outcome (at seeding) wins after enough one-sided buying. The -likelier outcome's reserve `y0` (for `p0 ≥ 50 %`) is small, so that side's loss -is correspondingly small. - -### 3.3 Bound (b): Void - -`⌊x/2⌋ ≥ (x−1)/2`, so two floors cost at most 1 unit. By AM–GM and L1, -`y + n ≥ 2√k0`. Hence - -``` -payout_Void ≥ √(y0·n0) + (cy+cn)/2 − 1. -``` - -Write `t = y0/n0 ≤ 1` (for `p0 ≥ 50 %`; symmetric otherwise). Then -`√(y0 n0) + (S − y0)/2 = S·(√t + (1−t)/2)` and `√t ≥ t` on `[0,1]` gives -`≥ S·(1+t)/2 ≥ S/2`.

Lemmas + +**L1 (k never falls).** After any `calc_buy` or `calc_sell`, `y'·n' ≥ y·n`. + +*Proof.* Buy: `r_other' = r_other + net` and +`r_bought' = ⌈r_bought·r_other / r_other'⌉ ≥ r_bought·r_other / r_other'`, +so `r_bought'·r_other' ≥ r_bought·r_other`. Sell: `r_other' = r_other − gross` +and `r_sold' = ⌈r_sold·r_other / r_other'⌉`, same inequality. ∎ + +By induction, every reachable state has **`y·n ≥ k0 = y0·n0`**, and `y, n ≥ 1` +(a buy keeps `r_bought' ≥ 1` because the ceiling of a positive number is at +least 1; a sell requires `gross < r_other`). So all bounds below are *infima*: +a reserve approaches but never reaches 0. + +**L2 (integer rounding is conservative).** For the same pool and the same +integer input, the pool never ends with less, and the trader never gets more, +than the exact-real constant-product model would give. + +*Proof by induction on the operation count.* Let `P(t)`: "after `t` +operations `y·n ≥ k0` and every operation so far was no better for the trader +than its real-valued counterpart". `P(0)` is equality. For the step: + +- *Buy.* The fee is `⌈in·f/10⁴⌉` so `net ≤ in·(1−f/10⁴)` (the trader never + gets more minted sets than the real model). With `net` fixed, + `r_bought'` is a ceiling of the real value `r_bought·r_other/(r_other+net)`, + hence `r_bought' ≥` real, hence `shares_out = r_bought + net − r_bought' ≤` + real shares out. +- *Sell.* `gross = ⌈out·10⁴/(10⁴−f)⌉ ≥` the real gross. The real shares-in + as a function of `g`, `g(ys, yo) = ys·yo/(yo − g) + g − ys`, is strictly + increasing in `g`, and the integer `shares_in` ceilings the first term, so + `shares_in ≥ g(gross) ≥ g(real gross)`. +- `y·n ≥ k0` is preserved by L1. + +The reserve of the bought/sold outcome in the integer model therefore +dominates the real one; the other reserve changes by the same `net` (buy) or by +`gross ≥` real gross (sell), always in the direction that costs the trader. ∎ + +The check is `check_one_step_dominance*` in the script, using `Fraction` as +the real-valued reference, over exhaustive small cases and random cases up to +`MAX_SETS`. + +## 3. LP worst-case loss + +Define the LP's loss as `S − payout` (excluding fee income, added in §3.4). + +### 3.1 Exact identities + +Because the creator's seed shares are part of its position, `payout_YES = +cy + y = (S − y0) + y`, so + +``` +loss_YES = y0 − y loss_NO = n0 − n +``` + +**The LP's loss under an outcome is exactly the fall of that outcome's pool +reserve.** (Forgetting `cy`/`cn` overstates the loss by up to `S`.) If traders +net-sell the winning outcome the reserve rises and the LP gains.

Since `max(y0, n0) = S` (the +likelier outcome's reserve equals the seed), the **worst case over outcomes is +`S − 1` stroops (infimum)**: the LP can lose essentially its entire seed if +the *unlikely* outcome (at seeding) wins after enough one-sided buying. The +likelier outcome's reserve `y0` (for `p0 ≥ 50 %`) is small, so that side's loss +is correspondingly small. + +### 3.3 Bound (b): Void + +`⌊x/2⌋ ≥ (x−1)/2`, so two floors cost at most 1 unit.

Anything else reverts with `InvalidAmount`; an empty list or - one longer than `max_batch()` reverts with `BatchTooLarge`. -2. **Chunk to `max_batch()`, read from the contract.** Never hardcode the - cap: `const { result: cap } = await contract.max_batch();`. Sort ids - ascending, then slice into chunks of at most `cap`. The committed - measurement table behind the cap is in the `MAX_BATCH` docstring in - `contracts/market-core/src/lib.rs`. -3. **Skips are per-market, not per-call.** A market that cannot pay out - right now (not found, not final, nothing to redeem, already claimed or - claimed by someone else, not the creator) comes back as - `{ status: { tag: "Skipped", … }, payout: 0 }` instead of aborting the - batch — one bad id never strands the rest. Only input validation - (rule 1) aborts the whole call. -4. **Simulate before signing.** The footprint scales with the chunk size; - `AssembledTransaction`'s simulate step (run by `signAndSend`, or - explicitly) surfaces contract errors and resource problems before - anything is submitted. -5. **Archived entries must be restored first.** If a market, position or - settlement entry has expired out of the live state, its restore must - happen in a *separate* transaction (e.g. `stellar tx restore-footprint`): - restores included in the batch transaction consume the 200-entry - disk-read budget and can push a full-size chunk over the limit. Run the - batch chunk against live state. -6. **One transfer per call.** The chunk's payouts arrive in a single token - transfer, so the balance delta equals `result.total` exactly — reconcile - on that, and use `result.items[i]` for per-market receipts. - -```ts -const { result: cap } = await contract.max_batch(); // u32, from the contract -const sorted = [...ids].sort((a, b) => Number(a - b)); // strictly ascending - -for (let i = 0; i < sorted.length; i += cap) { - const chunk = sorted.slice(i, i + cap); - const tx = await contract.redeem_many({ holder, market_ids: chunk }); - const { result } = await tx.signAndSend({ signTransaction }); - - const retry = result.items - .filter((it) => it.status.tag === "Skipped") - .map((it) => [it.market_id, it.status.values]); // e.g. drop AlreadyClaimed -} -``` - -The treasury contract mirrors both entry points (`redeem_many` / -`claim_pool_remainders`, same `BatchResult` shape) for positions it holds -itself; agents call those instead of market-core directly, and the -`max_batch()` on market-core still applies. - -## Reading TWAP prices - -`get_price(market_id)` is the instantaneous spot price; it is trivially -movable by a single trade. For anything automated (bots, alerts, fair-value -displays) prefer the accumulated oracle views: - -```ts -const { result } = await contract.twap({ market_id: 0n, window_secs: 900n }); -// price in bps of YES, time-weighted over the trailing 15 minutes -``` - -- `twap(market_id, window_secs)` — time-weighted average price in bps over - the trailing `window_secs`, floor-rounded. -- `observe(market_id, seconds_ago)` — the cumulative `price × seconds` - value at a past timestamp; difference two of them and divide for a - custom window. -- `price_cumulative(market_id)` — the same value at "now", for streaming - consumers that just want the accumulator. - -Caveats to design around: - -- Observations are written once per trade *timestamp*, so at most the most - recent 16 distinct-timestamp trades are covered; a `seconds_ago` (or - `window_secs` span) that reaches past them reverts with - `ObservationTooOld`. For long windows on busy markets, poll - `price_cumulative`/`observe` regularly and difference snapshots client-side, - or mirror the ring with `agents/core/strategy.ts`'s - `twapFromObservations`. -- Past the newest observation the last traded price is extended - counterfactually (this includes after `close_time`, until resolution), so - a quiet market's TWAP converges to its last price rather than failing. -- Interpolation between two observations is exact — price is piecewise - constant between trades — but `twap` floors, so off-chain comparisons - should floor identically. -- Markets created before the accumulator existed revert `NotSupported`; - fall back to `get_price` for them. - -## Splitting and merging complete sets - -Besides trading against the pool, holders can convert collateral to -shares and back at par without touching the pool: - -- `split(holder, market_id, amount)` pulls `amount` collateral from - `holder` and credits `amount` YES **and** `amount` NO to their - position. No fee, no price impact. -- `merge(holder, market_id, amount)` burns `amount` YES and `amount` - NO and pays `amount` collateral back. No fee, no price impact. - -Neither changes `fees_accrued` or the pool reserves. Both are authorized -by the holder and emit `SetsSplit` / `SetsMerged` respectively (decode these -in your indexer to track position changes that didn't come from a trade). - -Lifecycle differs between the two: - -- `split` requires the market to be `Open` and the current ledger time - to be strictly before `close_time`, and is blocked while the contract - is paused. After close, splitting has no purpose and opens timing - games. -- `merge` requires the market to be `Open`, but is allowed after - `close_time` and while the contract is paused. Merging is a pure - exit that cannot harm the pool, and letting users de-wait while the - resolver is slow is valuable. - -Merging requires both legs: `position.yes >= amount` and -`position.no >= amount`, otherwise it reverts with `InsufficientShares` -(#13). The creator after `seed_reserves` typically holds only one leg, so -a merge needs a buy or split first. - -To offer "merge all", call `quote_merge_max(market_id, holder)`, which -returns `min(position.yes, position.no)`. The same helper is exposed as -`math::merge_max` and mirrored in `model/fpmm_model.py` / `agents/core/src/fpmm.ts`. - -```ts -const max = (await contract.quote_merge_max({ market_id, holder: userAddress })).result; -if (max > 0n) { - const tx = await contract.merge({ holder: userAddress, market_id, amount: max }); - await tx.signAndSend({ signTransaction }); -} -``` - -Note that split sets count towards the per-market `sets_minted` cap and thus -can push a market into `MarketTooLarge` (#15) for future `buy` calls. See -`docs/architecture.md` for the griefing discussion and the chosen -mitigation. - -## Moving shares between wallets - -`transfer_position(from, to, market_id, outcome, amount)` sends outcome -shares to another wallet (the sender signs; `transfer_lp(market_id, -new_creator)` does the same for the creator/LP role). It is allowed while -the market is open and after resolution, up to the moment shares are -redeemed, and emits `PositionTransferred`. If your UI tracks balances -itself, handle that event (and `LpTransferred`); until your indexer does, -read balances from `get_position(market_id, holder)` rather than from -event-derived state. - -## Category enum - -`Category` is a plain enum (`Crypto | Macro | Geopolitics | Sports | Culture -| Other`) generated from the contract spec — build any category picker off -the bindings' `Category` type directly rather than hand-maintaining a -separate list, so the UI can never drift from what the contract accepts. - -## Reading trace data - -`reasoning-registry`'s `get_trace(trace_id)` returns -`{ market_id, agent, action, trace_hash, ipfs_cid, published_at }`. To show -a verified reasoning trace in the UI: - -1. Fetch the trace content from `ipfs_cid` (via a gateway, or through the - x402 service in `x402/` if it's gated behind payment). -2. Hash the exact bytes received (sha256) and compare to `trace_hash`. -3. Only render the content if the hashes match — never trust `ipfs_cid` - content without this check, since IPFS gateways are not authenticated. - -`x402/trace-verification.ts` has the reference hash-check implementation the -frontend can port. - -## Off-chain math mirrors - -```ts -import { calcSellShares } from "../agents/core/fpmm"; -``` - -The exact share-to-collateral inverse is implemented in three places -that must agree bit-for-bit: - -- "contracts/market-core/src/math.rs" — `isqrt` and `calc_sell_shares` - (the source of truth) -- "model/fpmm_model.py" — `calc_sell_shares` -- "agents/core/fpmm.ts" — `isqrt` and `calcSellShares` - -The older `collateralOutForShares` / `collateral_out_for_shares` inverses -still exist but are deprecated: they do not apply the pool-favouring -correction loop, so they can disagree with the contract by a few units. -Prefer `sell_shares` / `quote_sell_shares` on-chain, or `calcSellShares` / -`calc_sell_shares` off-chain. - -### Bindings interface versions - -`packages/bindings/*` start at `0.1.0`. A breaking interface change requires a -minor bump while the major is zero, then a major bump after 1.0.0; additions need -at least a patch.

Only input validation + (rule 1) aborts the whole call. +4. **Simulate before signing.** The footprint scales with the chunk size; + `AssembledTransaction`'s simulate step (run by `signAndSend`, or + explicitly) surfaces contract errors and resource problems before + anything is submitted. +5. **Archived entries must be restored first.** If a market, position or + settlement entry has expired out of the live state, its restore must + happen in a *separate* transaction (e.g. `stellar tx restore-footprint`): + restores included in the batch transaction consume the 200-entry + disk-read budget and can push a full-size chunk over the limit. Run the + batch chunk against live state. +6. **One transfer per call.** The chunk's payouts arrive in a single token + transfer, so the balance delta equals `result.total` exactly — reconcile + on that, and use `result.items[i]` for per-market receipts. + +```ts +const { result: cap } = await contract.max_batch(); // u32, from the contract +const sorted = [...ids].sort((a, b) => Number(a - b)); // strictly ascending + +for (let i = 0; i < sorted.length; i += cap) { + const chunk = sorted.slice(i, i + cap); + const tx = await contract.redeem_many({ holder, market_ids: chunk }); + const { result } = await tx.signAndSend({ signTransaction }); + + const retry = result.items + .filter((it) => it.status.tag === "Skipped") + .map((it) => [it.market_id, it.status.values]); // e.g. drop AlreadyClaimed +} +``` + +The treasury contract mirrors both entry points (`redeem_many` / +`claim_pool_remainders`, same `BatchResult` shape) for positions it holds +itself; agents call those instead of market-core directly, and the +`max_batch()` on market-core still applies. + +## Reading TWAP prices + +`get_price(market_id)` is the instantaneous spot price; it is trivially +movable by a single trade. For anything automated (bots, alerts, fair-value +displays) prefer the accumulated oracle views: + +```ts +const { result } = await contract.twap({ market_id: 0n, window_secs: 900n }); +// price in bps of YES, time-weighted over the trailing 15 minutes +``` + +- `twap(market_id, window_secs)` — time-weighted average price in bps over + the trailing `window_secs`, floor-rounded. +- `observe(market_id, seconds_ago)` — the cumulative `price × seconds` + value at a past timestamp; difference two of them and divide for a + custom window. +- `price_cumulative(market_id)` — the same value at "now", for streaming + consumers that just want the accumulator. + +Caveats to design around: + +- Observations are written once per trade *timestamp*, so at most the most + recent 16 distinct-timestamp trades are covered; a `seconds_ago` (or + `window_secs` span) that reaches past them reverts with + `ObservationTooOld`. For long windows on busy markets, poll + `price_cumulative`/`observe` regularly and difference snapshots client-side, + or mirror the ring with `agents/core/strategy.ts`'s + `twapFromObservations`. +- Past the newest observation the last traded price is extended + counterfactually (this includes after `close_time`, until resolution), so + a quiet market's TWAP converges to its last price rather than failing. +- Interpolation between two observations is exact — price is piecewise + constant between trades — but `twap` floors, so off-chain comparisons + should floor identically. +- Markets created before the accumulator existed revert `NotSupported`; + fall back to `get_price` for them. + +## Splitting and merging complete sets + +Besides trading against the pool, holders can convert collateral to +shares and back at par without touching the pool: + +- `split(holder, market_id, amount)` pulls `amount` collateral from + `holder` and credits `amount` YES **and** `amount` NO to their + position. No fee, no price impact. +- `merge(holder, market_id, amount)` burns `amount` YES and `amount` + NO and pays `amount` collateral back. No fee, no price impact. + +Neither changes `fees_accrued` or the pool reserves. Both are authorized +by the holder and emit `SetsSplit` / `SetsMerged` respectively (decode these +in your indexer to track position changes that didn't come from a trade). + +Lifecycle differs between the two: + +- `split` requires the market to be `Open` and the current ledger time + to be strictly before `close_time`, and is blocked while the contract + is paused. After close, splitting has no purpose and opens timing + games. +- `merge` requires the market to be `Open`, but is allowed after + `close_time` and while the contract is paused. Merging is a pure + exit that cannot harm the pool, and letting users de-wait while the + resolver is slow is valuable. + +Merging requires both legs: `position.yes >= amount` and +`position.no >= amount`, otherwise it reverts with `InsufficientShares` +(#13). The creator after `seed_reserves` typically holds only one leg, so +a merge needs a buy or split first. + +To offer "merge all", call `quote_merge_max(market_id, holder)`, which +returns `min(position.yes, position.no)`. The same helper is exposed as +`math::merge_max` and mirrored in `model/fpmm_model.py` / `agents/core/src/fpmm.ts`. + +```ts +const max = (await contract.quote_merge_max({ market_id, holder: userAddress })).result; +if (max > 0n) { + const tx = await contract.merge({ holder: userAddress, market_id, amount: max }); + await tx.signAndSend({ signTransaction }); +} +``` + +Note that split sets count towards the per-market `sets_minted` cap and thus +can push a market into `MarketTooLarge` (#15) for future `buy` calls. See +`docs/architecture.md` for the griefing discussion and the chosen +mitigation. + +## Moving shares between wallets + +`transfer_position(from, to, market_id, outcome, amount)` sends outcome +shares to another wallet (the sender signs; `transfer_lp(market_id, +new_creator)` does the same for the creator/LP role). It is allowed while +the market is open and after resolution, up to the moment shares are +redeemed, and emits `PositionTransferred`. If your UI tracks balances +itself, handle that event (and `LpTransferred`); until your indexer does, +read balances from `get_position(market_id, holder)` rather than from +event-derived state. + +## Category enum + +`Category` is a plain enum (`Crypto | Macro | Geopolitics | Sports | Culture +| Other`) generated from the contract spec — build any category picker off +the bindings' `Category` type directly rather than hand-maintaining a +separate list, so the UI can never drift from what the contract accepts. + +## Reading trace data + +`reasoning-registry`'s `get_trace(trace_id)` returns +`{ market_id, agent, action, trace_hash, ipfs_cid, published_at }`. To show +a verified reasoning trace in the UI: + +1. Fetch the trace content from `ipfs_cid` (via a gateway, or through the + x402 service in `x402/` if it's gated behind payment). +2. Hash the exact bytes received (sha256) and compare to `trace_hash`. +3. Only render the content if the hashes match — never trust `ipfs_cid` + content without this check, since IPFS gateways are not authenticated. + +`x402/trace-verification.ts` has the reference hash-check implementation the +frontend can port. + +## Off-chain math mirrors + +```ts +import { calcSellShares } from "../agents/core/fpmm"; +``` + +The exact share-to-collateral inverse is implemented in three places +that must agree bit-for-bit: + +- "contracts/market-core/src/math.rs" — `isqrt` and `calc_sell_shares` + (the source of truth) +- "model/fpmm_model.py" — `calc_sell_shares` +- "agents/core/fpmm.ts" — `isqrt` and `calcSellShares` + +The older `collateralOutForShares` / `collateral_out_for_shares` inverses +still exist but are deprecated: they do not apply the pool-favouring +correction loop, so they can disagree with the contract by a few units. +Prefer `sell_shares` / `quote_sell_shares` on-chain, or `calcSellShares` / +`calc_sell_shares` off-chain. + +### Bindings interface versions + +`packages/bindings/*` start at `0.1.0`.

It does change *how* the agent trades: + +- **Overshoot almost disappears.** With fixed trades, 10% of fills overshoot + the agent's own fair value. With edge-proportional sizing it is 0.2%, + because a small edge gets a small trade. +- **Prices end up closer to latent p**, and the caps bind less often. + +Both variants hit `max_market` on most markets. 89% of treasury calls revert +on a cap, because the agent keeps re-submitting while its edge persists. For +this edge size, the cap rather than the strategy decides the position. + +### B. k competing OracleDesk clones with the same signal + +`clones.json`, 50 runs per point. Each clone has its own treasury with the +caps above. The OracleDesk total is the sum over the clones (normal-approx 95% +CI of the per-run sum). + +| k | OracleDesk total PnL | per clone | mean abs mispricing (bps) | overshoot rate | `SlippageExceeded` reverts / run | capital at risk (k × max_market × markets) | +|---|---|---|---|---|---|---| +| 1 | 58.2 ± 90.2 | 58.2 | 652 | 0.109 | 62 | 2,500 | +| 2 | 135.5 ± 107.0 | 67.8 | 585 | 0.123 | 203 | 5,000 | +| 3 | −33.1 ± 140.5 | −11.0 | 493 | 0.115 | 413 | 7,500 | +| 4 | −17.9 ± 128.7 | −4.5 | 434 | 0.110 | 717 | 10,000 | +| 5 | 2.6 ± 129.4 | 0.5 | 383 | 0.129 | 1,099 | 12,500 | + +This is the systemic effect `docs/STATUS.md` warned about, now quantified: + +- **Profit does not scale with k; risk does.** The edge available is the LP's + mispricing. Identical clones split it, and past k = 2 they compete it away: + per-clone PnL falls to about zero. Meanwhile each clone's treasury caps + apply only to itself, so the capital committed to the same markets, and the + variance of the combined result, grow linearly in k. The CI half-width goes + from 90 to 129 USDC. +- **The clones collide.** Each one quotes against the same pre-step state, so + whichever executes second finds the price already moved and reverts on its + own slippage bound. `SlippageExceeded` reverts grow faster than linearly + (62 to 1,099 per run). With real fees, every revert also costs XLM. +- **Markets become more accurate.** Mean |price − p| drops from 652 to + 383 bps as more capital corrects the LP's mispricing. Most of that gain goes + to accuracy, not to the clones. + +A per-deployment cap cannot limit any of this.

Use a private submission path, or bounds +derived from an independent price, before trading against adversarial flow. + +## Extending + +- **New agent:** implement `SimAgent` in `sim/agents/`, add a config variant in + `sim/engine.ts`'s `AgentConfig` and `buildAgents`, and draw randomness only + from the `rng` passed to `act`. +- **New strategy:** pass a `strategy` function with `decideTrade`'s signature + to `OracleDeskTrader`. +- **Treasury checks:** when the shared treasury risk mirror lands, replace + `sim/treasury.ts`'s cap code with it (see the TODO there).
