ECH-03 (#422) covers budget allocation on the echidna side. Decide which layer owns which budget before implementing. +- Verified in echidna: a `timeout` status in `echidna.prove.result/1` means "budget ran out; retry with a larger `--timeout`". It is not a failure, and the scheduler must keep that distinction. + +## Proposed Work + +- **Runtime model.** For each `(repo, prover)` (optionally also per file-path bucket), keep an empirical runtime distribution of successful runs from `proof_results` / `proof_jobs`. Use a robust quantile estimate (for example P90 or P95) with a minimum sample count, and fall back to the static timeout when history is too short. +- **Adaptive timeout.** `timeout = clamp(q_p * margin, floor, ceiling)`, where `ceiling` is the configured static timeout, so adaptation can only **shorten** waiting on known-fast provers and never makes an existing gate stricter. A timeout under the adaptive limit triggers one retry at the static ceiling before it is reported, so tightening never creates a new failure. +- **Solver ordering and selection for PR gates.** Order jobs by expected time-to-verdict (success probability ÷ expected runtime, from history). Where the repo's config marks provers as interchangeable for a goal class, allow "first verified wins" with cancellation of the rest. Otherwise run all required provers, because coverage gating needs them. Default: ordering only, with no skipping. +- **Exploration.** Use a small, configurable exploration rate (for example ε-greedy or UCB) so that rarely chosen provers keep current statistics. It is off by default for regulator-mode repos. +- **Config.** Add a new `[scheduler.adaptive]` section (enabled, quantile, margin, floor, min_samples, exploration). It is disabled by default.

There is no early exit after the first success, no reordering and no composition. +- *[unverified]* Some playbook entries are already hand-made composites (for example `by (simp; linarith)` and `by (transfer, simp add: algebra_simps)`). This shows that combinators are useful, but they are not generated. +- *[unverified]* `AttemptResult` has the variants `Succeeded { duration_ms, receipt }`, `Failed { error, duration_ms }`, `Timeout` and `Skipped { reason }`. `Timeout` carries no duration. +- *[unverified]* `derive_learning` records successes as `positive` learnings and failures as `anti-pattern` learnings in the ledger. Failures are sorted into `undefined-reference`, `tactic-mismatch`, `structural-mismatch` and `generic-failure`. These classes can drive move selection. +- Verified in echidna: probes are checked by `echidna prove`, which can emit one `echidna.prove.result/1` JSON line (`docs/PROVE-RESULT-CONTRACT.adoc`). Its `status` is one of `verified`, `failed`, `error`, `timeout`, `unknown`, and it includes `duration_ms` and `trust.axioms`. The contract has **no partial-progress field** (for example, remaining subgoals). Any partial evaluation that needs subgoal counts would either need a new, additive contract field in echidna or have to parse prover output inside proof-burrower. +- ParadisEO is referenced only in the roadmap. This issue is about the *algorithms* (neighbourhoods, delta evaluation, local search). It does not require a C++ ParadisEO dependency. + +## Proposed Work + +- **Solution representation.** A candidate is a short sequence of tactic steps joined by combinators (`;`, `,`, `<|>`-style fallback where the prover supports it). Each step is drawn from the specialist's existing `TacticTemplate`s plus their simplifier-set variants. Cap the length (for example ≤ 3 steps) so the space stays small. +- **Neighbourhood moves.** Define these as pure functions: insert a step, delete a step, swap adjacent steps, replace a step's tactic, add or remove a simp-set argument. Each move must have a stable textual identity, so results can be cached. +- **Delta / partial evaluation, cheapest first:** + 1. *Ledger lookup:* if `(goal_id, script)` already has a recorded outcome, reuse it at no prover cost. + 2. *Anti-pattern pruning:* reject neighbours whose prefix matches a recorded `anti-pattern` learning for this specialist and goal shape. + 3. *Prefix evaluation (optional, behind a flag):* when a prefix's outcome is known to fail with `tactic-mismatch`, skip all extensions of that prefix. + 4. *Full evaluation:* run `run_probe` only for surviving neighbours, within a per-goal prover-call budget. +- **Search driver.** Use first-improvement hill climbing with a tabu list over move identities, plus an iteration cap and a prover-call cap. Stop on the first `Succeeded`. Make the driver deterministic for a given seed. +- **Fitness.** Lexicographic: (1) verified beats everything else; (2) fewer `trust.axioms`; (3) shorter script; (4) lower `duration_ms`.

Currently, multi-prover portfolios allocate static compute timeouts across backends (e.g., 5 seconds to Z3, 10 seconds to Vampire, 15 seconds to Isabelle). In large-scale distributed runs, this leads to idle compute cores and redundant search paths. ParadisEO's parallel modules (smp and peo) model optimization as an Island Model with asynchronous migration topologies and dynamic parameter control. Applying these distributed metaheuristic topologies to Chapel will optimize CPU allocation and proof search diversity. + - **Proposed Changes:** + - Island-Model Proof Exploration on Chapel Locales: Map each Chapel locale to a dedicated "proof island" exploring distinct tactic spaces or solver configurations. Implement asynchronous migration policies: periodically exchange promising intermediate lemmas, simplified sub-goals, and unprovability warrants between locales across PGAS channels + - Dynamic Compute Budget Allocation: Track early progress markers (clause generation rates in first-order ATPs, simplification step velocity in Isabelle/Lean). Use adaptive resource reallocation (inspired by ParadisEO's dynamic parameter adaptation) to divert CPU threads and memory limits from stalled prover processes toward converging solver branches + - Diversity-Preserving Niching: Incorporate fitness sharing / niching across locales to prevent worker tasks from redundantly exploring identical lemma combinations + - **Acceptance Criteria:** + - Multi-locale Chapel execution (CHPL_COMM=gasnet or sockets) passes verification suite with zero data races + - Proof portfolio completes corpus benchmarks with measurable reduction in cumulative core-hours compared to static timeout scheduling + - Asynchronous migration across locales remains non-blocking and robust against single-backend worker crashes + - **References:** ParadisEO SMP/PEO modules: smp, peo in nojhan/paradiseo, Chapel PGAS Distributed Architecture docs + - **Status:** Open + +- **feat(ml): black-box hyperparameter & temperature calibration for GNN premise rankers via CMA-ES / EDO** + - **Target Repository:** hyperpolymath/echidna + - **Area:** src/julia/, ml/premise_selection/, verification/confidence.rs + - **Description:** ECHIDNA's Julia ML subsystem uses Graph Neural Networks (GNNs) to embed formal terms and rank candidate lemmas/tactics for premise selection. The output probabilities are combined with Bayesian confidence posteriors and Dempster-Shafer belief combinations before being dispatched to backend provers. Because end-to-end proof success is a non-differentiable step function (0/1 for timeout/fail/pass), standard backpropagation cannot optimize post-inference parameters such as: Softmax temperature scaling factors across heterogeneous prover kinds, Bayesian prior weights for different mathematical domains (algebra, topology, logic), Cutoff thresholds for premise candidate truncation. ParadisEO's EDO (Estimation of Distribution Optimization) module implements adaptive normal distributions and Covariance Matrix Adaptation Evolution Strategies (CMA-ES), which excel at continuous black-box parameter calibration on non-smooth surfaces. + - **Proposed Changes:** + - Calibration Runner in Julia/Rust: Create a parameter calibration harness that runs against benchmark corpora (e.g., Isabelle AFP subset, CoqHammer lemmas). Expose vector parameter inputs for (τ_temp, w_prior, k_cutoff, α_dempster) + - CMA-ES / EDA Integration: Adapt ParadisEO's edoNormalAdaptive / CMA-ES covariance update rule to search the parameter space.

While the current implementation calculates simple non-dominated fronts, multi-prover portfolios often produce dense, high-dimensional candidate clouds (e.g. fast Level-2 SMT proofs vs. moderate Level-4 Isabelle proofs vs. slow Level-5 dual-kernel Coq/Lean certificates). Drawing principles from ParadisEO-moeo (Multi-Objective Evolutionary Optimization), we can enhance ECHIDNA's frontier selection with exact hypervolume indicators and active crowding-distance diversity metrics. + - **Proposed Changes:** + - Fast Non-Dominated Sorting (NSGA-II / SPEA2): Implement efficient O(M·N²) non-dominated sorting algorithm from moeo to assign rank levels to candidate proofs. Introduce crowding distance / niching to preserve diversity when pruning candidate proof pools before presenting to the user or downstream consumers + - Exact Hypervolume Indicator (HVC): Implement dimension-bounded exact hypervolume contribution metrics to quantify the relative quality increase of a new proof candidate against the reference nadir point (worst case: max timeout, Trust Level 1, max memory, max proof size) + - Multi-Objective Quality Metric in echidna.prove.result/1: Expose the hypervolume contribution and front rank in the JCS-canonical I-JSON output receipt so downstream clients (such as echidnabot and proof-burrower) can make informed trade-off selections + - **Technical Invariants & Verification:** + - Total Order on Frontier Scores: The Pareto ranking must satisfy strict anti-symmetry and transitivity under floating/fixed-point arithmetic + - Trust-Level Monotonicity: A proof candidate with strictly higher trust level must never be dominated by a lower-trust candidate unless explicitly disqualified by hard resource caps + - Unit & Property Tests: Add property-based tests in tests/pareto_tests.rs (using proptest) verifying that no candidate on Front k dominates any candidate on Front j where j] timeout_seconds` is wired into dispatch -- Need to verify if `[scheduler] job_timeout_seconds` exists -- `proof_jobs`, `proof_results`, `tactic_outcomes` tables exist +Verified against echidnabot@ae5283323b815f82d2a556080b59e0bb648de62b: +- `enqueue_repo_jobs` in `src/api/webhooks.rs` creates one job per enabled prover (VERIFIED: iterates over `repo.enabled_provers`) +- `JobLimiter` defaults to 10 global / 3 per repo concurrent jobs (VERIFIED: in limiter.rs) +- Static 300 second timeouts are used as default (VERIFIED: `default_timeout()` returns 300 in config.rs) +- `manifest [provers.] timeout_seconds` is wired into dispatch (VERIFIED: accessed in manifest.rs, used in echidna_client.rs) +- `[scheduler] job_timeout_seconds` does NOT exist (CORRECTED: comment in manifest.rs claiming it exists is wrong) +- `proof_jobs`, `proof_results`, `tactic_outcomes` tables exist (VERIFIED: in migrations/20260602000001_initial_schema.sql) ## Proposed Changes diff --git a/.github/issues/proof-burrower-01-combinatorial-tactic-synthesis.md b/.github/issues/proof-burrower-01-combinatorial-tactic-synthesis.md index 4b11241c..97ebcf72 100644 --- a/.github/issues/proof-burrower-01-combinatorial-tactic-synthesis.md +++ b/.github/issues/proof-burrower-01-combinatorial-tactic-synthesis.md @@ -6,7 +6,7 @@ **Labels:** enhancement, area:swarm, rust, search-tactics **Status:** Draft (unverified) -**Provenance:** Based on read-only look at proof-burrower@be897dd8 +**Provenance:** Based on read-only look at proof-burrower@be897dd07e1a16014f2d0f8d9cbedffb0240dd4a --- @@ -16,11 +16,11 @@ The Proof Burrower system performs automated tactic selection and proof search.
