+# Documentation Voice — Aleo Python SDK
+
+How docstrings and prose read in this repo. The rules bind; the examples show
+them in practice. This is a **Python** SDK — docstrings, not JSDoc; types live
+in annotations, not in the prose.
+
+## Docstrings
+
+Lead with a present-tense verb, give one or two sentences of context (including
+side effects — network, fee, local-only), and describe each argument, return
+value, and raised error **by its consequence**. Do not restate types the
+signature already carries.
+
+### Good
+
+```python
+def transfer_public(self, recipient: str, amount: int) -> BoundCall:
+    """Build a public ``credits.aleo`` transfer call.
+
+    Returns an unexecuted call — nothing touches the network until you invoke a
+    verb (``.simulate``, ``.build_transaction``, ``.transact``, ``.delegate``).
+
+    Args:
+        recipient: The destination address (``aleo1…``).
+        amount: Microcredits to send; coerced to ``u64`` from the program's
+            declared input type.
+
+    Returns:
+        A bound call; ``.transact(account)`` builds, proves, and broadcasts it.
+
+    Raises:
+        ProgramNotFound: If ``credits.aleo`` is not loaded in the process.
+    """
+```
+
+Why it works: starts with "Build"; the second sentence names the key behavior
+(nothing runs until a verb — the footgun-preventing fact); each arg is described
+by what it *means*, not its type; `Raises` names the concrete failure a caller
+would catch.
+
+### Bad
+
+```python
+def transfer_public(self, recipient, amount):
+    """This function allows you to easily and powerfully build a transfer in a
+    seamless way. It takes a recipient and an amount and returns a result.
+
+    :param recipient: the recipient (string)
+    :param amount: the amount (int)
+    :return: the result
+    """
+```
+
+Why it fails: filler ("easily", "powerfully", "seamless"); restates types; says
+"a result" instead of what you get and what you do with it; no side-effect or
+error information.
+
+## Naming in prose and examples
+
+- Use the Pythonic surface: properties (`key.address`, not `key.address()`),
+  `str(x)`/`bytes(x)` not `.to_string()`/`.to_bytes()`, `PrivateKey.random()`.
+- Prefer the named algebraic method in prose where it reads clearer
+  (`a.add(b)`), the operator in code examples (`a + b`) — both exist.
+- Examples must run as written against the documented signature. Mark any
+  snippet that touches the network or downloads proving parameters.
+- Say "microcredits" explicitly for `u64` fee/amount values; never leave the
+  unit implicit.
+
+## Privacy stance
+
+This is a privacy chain. Do not document or add affordances that link
+signatures to signer addresses (no `recover`-style verb). When a feature shares
+secret material with a service (e.g. delegated record scanning shares the view
+key), state that tradeoff plainly and point to the self-hosted alternative.

+"""Merge the testnet extension module into the mainnet aleo wheel.
+
+maturin builds exactly one cdylib per invocation, named by pyproject
+[tool.maturin] module-name. To ship a single `aleo` wheel containing BOTH
+`aleo/_aleolib_mainnet*.so` and `aleo/_aleolib_testnet*.so`, we build two wheels
+(mainnet, then testnet with module-name overridden) and splice the testnet .so
+into the mainnet wheel here, regenerating the RECORD so the wheel stays valid.

+Usage:

+# Aleo Python SDK — Agent Guide
+
+Python SDK for Aleo: PyO3 bindings over **snarkvm v4.8.1** plus pure-Python
+client / record-scanner / delegated-proving layers and a Web3.py-style facade.
+Two shipped packages:
+
+| Path | Package | What |
+| --- | --- | --- |
+| `sdk/` | `aleo` | the PyO3 crate (`_aleolib_mainnet`) + the `aleo` Python package (accounts, algebra, programs, records, algorithms, network client, record scanner, facade) |
+| `sdk-abi/` | `aleo-abi` | a **separate** package that generates contract ABIs from Aleo bytecode via Leo's `leo-abi` crate; kept isolated so Leo's snarkvm feature flags never reach the main crate |
+
+## Build & test
+
+```sh
+cd sdk && python3 -m venv .env && . .env/bin/activate && pip install maturin
+maturin develop --features mainnet          # build + install the extension
+python -m pytest python/tests -m "not slow"  # fast suite (what CI runs)
+python -m pytest python/tests -m slow         # network/proving tests (run locally)
+npx -y pyright@latest                         # strict type check (must be 0)
+cargo fmt --check && cargo clippy --no-default-features --features mainnet -- -D warnings
+cargo check --no-default-features --features testnet   # guard the testnet cfg seam
+```
+
+Run pytest from the package dir so it uses that package's `pytest.ini`
+(`sdk/pytest.ini`, `sdk-abi/pytest.ini`) — a legacy root `setup.cfg` injects
+addopts if you invoke pytest from the repo root.
+
+## Architecture conventions (follow these)
+
+- **Two-build, no macro.** One flat codebase; `CurrentNetwork`/`CurrentAleo`
+  are cfg-selected (`--features mainnet|testnet`) and compiled once per network
+  into `_aleolib_mainnet` / `_aleolib_testnet`, exposed as `aleo.mainnet.*` /
+  `aleo.testnet.*`. The Web3.py facade sits on top; network comes from the
+  provider.
+- **Sync + async pairs.** Every HTTP client ships both (`AleoNetworkClient` /
+  `AsyncAleoNetworkClient`, scanner likewise, `Aleo` / `AsyncAleo`): sync on
+  `requests`, async on `httpx`, shared pure logic in a common module — never
+  duplicate orchestration.
+- **Pythonic (anti-viem) surface.** snake_case; pure getters are `@property`;
+  Python dunders (`__str__`/`__bytes__`/`__eq__`/`__hash__`) over
+  `to_string()/to_bytes()/equals()`; explicit `PrivateKey.random()` (no
+  implicit-RNG constructor). Do NOT mirror the TS/viem method names where a
+  Python idiom exists.
+- **Algebraic types expose BOTH** a dunder and a named method (`__add__`+`add`,
+  `__mul__`+`multiply`, Group `__mul__`+`scalar_multiply`, `__neg__`+`negate`).
+  snarkvm's `inverse()` is negation → expose as `negate`, never `inverse`.
+- **Both stubs.** Update `python/aleo/_aleolib_mainnet.pyi` (`list[...]` style)
+  AND `python/aleo/__init__.pyi` (`List[...]` style) for every binding change.
+  Pure-Python modules need no stub — annotate inline; pyright strict must pass.
+- **aleo-abi isolation.** Never add a Leo crate to `sdk/`. The CI `test-abi`
+  lane asserts `dev_skip_checks` never appears in `sdk/Cargo.lock`.
+
+## Testing discipline
+
+- Known-answer vectors are vendored from `ProvableHQ/sdk` (and its `wasm/`
+  crate) with a `_source` note (path + commit). Copy constants character-exact.
+- **Never weaken an assertion to make a test pass.** A KAT mismatch is a real
+  signal — report it, don't paper over it.
+- Proving / live-network tests are `@pytest.mark.slow` (SRS downloads, live
+  REST); CI runs `-m "not slow"`.
+
+## Delegated services (DPS + record scanner)
+
+**Auth, proving, and scanning are all Provable *services* on `api.provable.com`,
+hosted at the API ORIGIN — NOT under the read node's `/v2/{network}` base.** The
+read/RPC endpoints live at `https://api.provable.com/v2/{network}/…`; the
+services hang off the bare origin (`https://api.provable.com`) at their own path
+prefixes. Each is confirmed working against live testnet (see
+`tests/e2e/test_testnet_e2e.py`):
+
+- **JWT auth** — origin, no prefix: `POST {origin}/jwts/{consumerId}`. Derive the
+  origin with `jwt_origin(base_url)` (`scheme://host`, path stripped).
+- **Delegated proving** — `{origin}/prove/{network}` prefix:
+  - `GET {origin}/prove/{network}/pubkey` — ephemeral X25519 key + key id + a
+    `Set-Cookie` **affinity** session. The ephemeral private key lives only on
+    the backend that served this call, so the follow-up `/prove` MUST stick to
+    it: rely on the client cookie **jar** (requests.Session / httpx.AsyncClient)
+    to re-send the cookie — do NOT hand-build a `Cookie` header from
+    `set-cookie` (comma-joins multiple cookies, carries attributes, and bypasses
+    the jar).
+  - `POST {origin}/prove/{network}/prove/authorization` (or `/prove/request`) —
+    sealed-box `{key_id, ciphertext}`; JWT + the affinity cookie; SDK retries
+    500/503.
+- **Record scanner** — `{origin}/scanner/{network}` prefix (env
+  `RECORD_SCANNER_URL=https://api.provable.com/scanner`).
+
+Documented endpoints (docs describe paths *relative to the service base*; the
+base is the origin + service prefix above):
+- Register → API key: `POST /consumers` — https://docs.provable.com/docs/api/services/get-auth-register
+- Issue/refresh JWT: `POST /jwts/:consumerId` (send `X-Provable-API-Key`; JWT
+  returns in the `Authorization: Bearer …` header) — https://docs.provable.com/docs/api/services/issue-jwt
+- Ephemeral prover pubkey: `GET /pubkey` — https://docs.provable.com/docs/api/services/get-prove-pubkey
+- Submit proving: `POST /prove/authorization` (the authorization endpoint; the
+  docs also describe a `/prove/encrypted` variant). https://docs.provable.com/docs/api/services/post-prove-encrypted
+
+Tests read `ALEO_CONSUMER_ID` / `ALEO_DPS_API_KEY` from the env; the client mints
+and refreshes JWTs automatically. The prover base defaults to
+`{jwt_origin(base_url)}/prove/{network}` — override via `HTTPProvider(prover_uri=…)`
+only to point at a non-default prover host.
+
+## Working process
+
+Multi-step work is tracked in `.superpowers/sdd/progress.md` (git-ignored) with
+a review gate per task. Specs/plans live under `docs/superpowers/` (git-ignored,
+kept local). Documentation voice: see `.agents/voice.md`.

 Welcome to the Aleo Python SDK! This SDK provides a set of libraries aimed at empowering Python developers with zk (zero-knowledge) capabilities.
 
-## Quick Start
+The SDK ships two layers:
+
+- A **Web3.py-style facade** (`aleo.Aleo` / `aleo.AsyncAleo`) — a high-level, batteries-included client for connecting to a node, managing accounts, reading state, and building/proving/broadcasting transactions.
+- **Low-level primitives** (`aleo.mainnet`, `aleo.testnet`) — direct Python bindings to Aleo's zero-knowledge cryptographic types, for when you need full control.
+
+Built with snarkvm 4.8.1 (MainnetV0). For build instructions, see [sdk/Readme.md](./sdk/Readme.md).
+
+## Quick Start (facade)
+
+```python
+from aleo import Aleo
+
+# Connect (construction is offline — no I/O until you make a call)
+aleo = Aleo(Aleo.HTTPProvider("https://api.provable.com/v2"))
+print(aleo.network_name)   # "mainnet"
+print(aleo.network_id)     # 0
+
+# Create an account (local)
+account = aleo.account.create()
+print(account.address)     # aleo1…
+
+# Read a public balance  # requires a live node
+balance = aleo.get_balance(str(account.address))
+print(aleo.from_microcredits(balance), "credits")
+```
+
+`Aleo.HTTPProvider` is also importable directly as `from aleo import HTTPProvider`; the two are equivalent.
+
+## The verb ladder (sync)
+
+The facade follows a clean top-to-bottom narrative: **connect → account → read → build a call → inspect → send**. Each rung does a little more than the one above it.
+
+### 1. Connect
+
+```python
+from aleo import Aleo
+
+aleo = Aleo(Aleo.HTTPProvider("https://api.provable.com/v2"))
+
+# Optional: check reachability  # requires a live node
+if aleo.is_connected():
+    print("connected to", aleo.network_name)
+```
+
+`HTTPProvider` is a *config object*, not a live connection — it is safe to construct without a network. It accepts `network=` (`"mainnet"` / `"testnet"`), `api_key=`, `prover_uri=` (the DPS endpoint), `headers=`, and a custom `transport=` callable.
+
+### 2. Account — create or import (local)
+
+```python
+# Fresh random account
+account = aleo.account.create()
+
+# Import from a private-key string (or a PrivateKey object)
+account = aleo.account.from_private_key("APrivateKey1zkp…")
+
+# Derive deterministically from a field seed
+account = aleo.account.from_seed("123field")
+
+# Sign / verify (bytes)
+sig = aleo.account.sign(b"hello aleo", account)
+assert aleo.account.verify(str(account.address), b"hello aleo", sig)
+
+# Sign / verify a typed Aleo value
+sv = aleo.account.sign_value("100u64", account)
+assert aleo.account.verify_value(str(account.address), "100u64", sv)
+```
+
+Set `aleo.default_account = account` and the verbs below will use it whenever you omit the signer.
+
+> **Note:** the facade deliberately has no "recover signer from signature" verb. Aleo is a privacy chain — surfacing "which address signed this?" is a de-anonymisation vector. The low-level `Signature.to_address()` primitive remains available directly if you truly need it.
+
+### 3. Read — balance and mappings
+
+```python
+# Public credits balance in microcredits (0 if the address is unfunded)  # requires a live node
+micro = aleo.get_balance(str(account.address))
+print(aleo.from_microcredits(micro), "credits")
+
+# Read any on-chain mapping through a bound Program  # requires a live node
+credits = aleo.programs.get("credits.aleo")
+raw = credits.mapping("account").get(str(account.address))
+print("account mapping value:", raw)
+```
+
+Unit helpers are local: `aleo.to_microcredits(1.5) == 1_500_000` and `aleo.from_microcredits(1_500_000) == 1.5`. Address validation is local too: `aleo.is_valid_address(s) -> bool`.
+
+### 4. Build a call
+
+`aleo.programs.get(...)` fetches a program and exposes its transitions as `program.functions.<name>`, mirroring web3.py's ABI-driven `contract.functions`. Calling one **coerces your Python arguments to Aleo values** and returns a `BoundCall`:
+
+```python
+# requires a live node (to fetch the program source)
+credits = aleo.programs.get("credits.aleo")
+
+call = credits.functions.transfer_public(str(account.address), 1_000_000)
+print(call.signature)   # "transfer_public(address, u64)"
+print(call.args)        # ['aleo1…', '1000000u64']  — coerced
+```
+
+You can also list/iterate the available functions: `list(credits.functions)`, `"transfer_public" in credits.functions`.
+
+### 5. Inspect — `simulate` / `.decoded()`
+
+Before proving or broadcasting anything, build the **authorization locally** and look at what the call will produce. This is a proof-free, network-free dry run:
+
+```python
+auth = call.simulate(account)          # alias of .authorize(); .call() also works
+print(auth.outputs)                    # per-transition output lists
+print(auth.decoded())                  # [{program, function, inputs, outputs}, …]
+```
+
+Both `AuthorizationResult` and `TransactionResult` expose the same `.outputs` / `.decoded()` surface, plus a `.raw` escape hatch to the underlying network object. You can also decode after the fact with `aleo.decode_transition(tx_id_or_transition)`.
+
+### 6. Transact — full prove + broadcast
+
+`build_transaction` (alias `prove`) runs the whole ladder locally: authorize → execute → prepare trace → prove execution → authorize+prove fee → assemble. `transact` does that **and** broadcasts, returning the transaction id:
+
+```python
+# requires a live node + funded private key
+tx_id = credits.functions.transfer_public(
+    str(account.address), 100
+).transact(account)
+
+confirmed = aleo.network.wait_for_transaction(tx_id, timeout=60.0)
+```
+
+Fees are **public by default** (base cost from the execution). Pass `priority_fee=` for a tip, or opt into a **private fee** with `private_fee=True` (auto-sourced from `aleo.record_provider`) or by passing an explicit `fee_record=`.
+
+### 7. Delegate — the flagship path (fee master pays by default)
+
+`delegate` hands proving to a **Delegated Proving Service (DPS)**: you build only the lightweight main authorization locally, and the DPS does the expensive SNARK proving. By default **the prover's fee master pays the fee** — no records, no public fee, no friction. That frictionlessness is the whole point.
+
+```python
+# requires prover credentials; fee master pays
+result = credits.functions.transfer_public(
+    str(account.address), 100
+).delegate(account)
+```
+
+Want to pay your own fee instead? `delegate(account, pay_own_fee=True)` (public) or `delegate(account, fee_record=<credits record>)` (private). Both bind the fee to the real execution id, so they prove the execution locally first. `broadcast=False` returns the proven transaction without submitting it.
+
+### Private transfers — delegated proving + record discovery
+
+A full private transfer combines the two trust-minimising paths: **delegated proving** (the prover's fee master pays) and a **record provider** to discover the private records you own. The default record provider (`aleo.records`) uses Provable's hosted scanner — registering shares your view key with that service so it can index your records. If you'd rather not share a view key, assign your own `RecordProvider` instead.
+
+```python
+# requires prover credentials + hosted-scanner registration
+credits = aleo.programs.get("credits.aleo")
+
+# 1) Move public credits into a private record (delegated — fee master pays)
+credits.functions.transfer_public_to_private(str(account.address), 100_000) \
+    .delegate(account)
+
+# 2) Register with the record provider and find the new private record
+aleo.records.register(account)                 # shares the view key with the scanner
+record = aleo.records.get_unspent(program="credits.aleo", record="credits")
+
+# 3) Spend the private record with a private transfer (delegated)
+credits.functions.transfer_private(record, str(recipient.address), 1) \
+    .delegate(account)
+```
+
+`aleo.record_provider` is swappable: set it to your own object implementing the `RecordProvider` protocol (`get_unspent` / `find`) — e.g. a self-hosted scanner — and the whole facade (including private-fee auto-sourcing) uses it, with no view-key sharing.
+
+## Async (`AsyncAleo`)
+
+The async facade mirrors the sync surface. Construction and the local, CPU-bound steps stay synchronous; everything that touches the network is awaitable.
+
+```python
+import asyncio
+from aleo import AsyncAleo
+
+async def main():
+    aleo = AsyncAleo(AsyncAleo.HTTPProvider("https://api.provable.com/v2"))
+    print(aleo.network_name)   # sync — no I/O
+
+    # Account ops are sync (purely local), even on AsyncAleo
+    account = aleo.account.create()
+    sig = aleo.account.sign(b"hi", account)
+    assert aleo.account.verify(str(account.address), b"hi", sig)
+
+    # Reads are awaited  # requires a live node
+    micro = await aleo.get_balance(str(account.address))
+    print(aleo.from_microcredits(micro), "credits")
+
+    # Build a call — fetching the program is awaited  # requires a live node
+    credits = await aleo.programs.get("credits.aleo")
+    call = credits.functions.transfer_public(str(account.address), 100)
+
+    # authorize / simulate / call are SYNC (local proof-free build)
+    auth = call.simulate(account)
+    print(auth.decoded())
+
+    # transact / delegate are awaited  # requires a live node / prover creds
+    tx_id = await call.transact(account)
+    result = await call.delegate(account)   # fee master pays by default
+
+asyncio.run(main())
+```
+
+**Sync vs async on the async facade:**
+
+- **Sync (local, no I/O):** `account.*` (create/import/sign/verify), `to_microcredits` / `from_microcredits` / `is_valid_address`, and `authorize` / `simulate` / `call` on a bound call.
+- **Async (awaitable):** `is_connected`, `get_balance`, `programs.get`, mapping reads, `build_transaction` / `transact` / `delegate`. Heavy proving runs in `asyncio.to_thread` so it does not block the event loop.
+
+## Testing utilities (`aleo.testing`)
+
+The SDK ships an eth-tester-style harness for fast, deterministic local testing.
+
+### `Devnode` — a local chain in a context manager
+
+`Devnode` launches a local [`aleo-devnode`](https://github.com/ProvableHQ/aleo-devnode) with **manual block creation**, so tests control exactly when blocks are produced. It auto-picks a free port and tears the node down on exit.
+
+```python
+from aleo.testing import Devnode
+
+with Devnode() as dn:
+    aleo = dn.aleo                 # an Aleo client wired to the devnode
+    alice = dn.accounts[0]         # 5 deterministic, pre-funded genesis accounts
+
+    tx_id = aleo.programs.get("credits.aleo").functions.transfer_public(
+        str(dn.accounts[1].address), 1_000_000
+    ).transact(alice)
+
+    dn.advance(1)                  # produce 1 block to confirm the tx
+    snap = dn.snapshot()           # capture chain state
+```
+
+- `dn.aleo` — an `Aleo` client pointed at the devnode.
+- `dn.accounts` — 5 deterministic, pre-funded genesis accounts.
+- `dn.advance(n)` — produce `n` blocks (the node runs with manual block creation).
+- `dn.snapshot()` — capture the current chain state.
+
+Requires the `aleo-devnode` binary on your `PATH`, or set `$ALEO_DEVNODE_BIN` to its location.
+
+### Live end-to-end tests
+
+The `-m slow` live tests hit a real testnet and **skip automatically when their environment variables are unset**:
+
+| Variable | Purpose |
+| --- | --- |
+| `ALEO_E2E_PRIVATE_KEY` | A funded testnet private key |
+| `ALEO_E2E_ENDPOINT` | Node/API endpoint to test against |
+| `ALEO_E2E_API_KEY` | Provable API key |
+| `ALEO_E2E_CONSUMER_ID` | DPS consumer id for delegated proving |
+
+The `-m devnode` tests additionally require the `aleo-devnode` binary (see `Devnode` above).
+
+## Low-level primitives
+
+When you need direct control, import the network module and use the cryptographic types directly:
 
 ```python
 from aleo.mainnet import PrivateKey, Signature
 
-# Generate a random private key
 pk = PrivateKey.random()
-print(f"Address: {pk.address}")
-print(f"View Key: {pk.view_key}")
+print(pk.address, pk.view_key)
 
-# Sign and verify a message
-message = b"hello"
-sig = Signature.sign(pk, message)
-assert sig.verify(pk.address, message)
+sig = Signature.sign(pk, b"hello")
+assert sig.verify(pk.address, b"hello")
 ```
 
-Built with snarkvm 4.7.3 (MainnetV0). For build instructions, see [sdk/Readme.md](./sdk/Readme.md).
+`aleo.mainnet` (and `aleo.testnet`, when the extension is compiled) expose the full type set — `Account`, `Program`, `Process`, `Authorization`, `Transaction`, `RecordPlaintext`, `Field`, `Address`, and more.

+aleo = Aleo(Aleo.HTTPProvider("https://api.provable.com/v2"))

+```
+
+`Aleo.HTTPProvider` is also importable directly as `from aleo import HTTPProvider`; the two are equivalent.
+
+## The verb ladder (sync)
+
+The facade follows a clean top-to-bottom narrative: **connect → account → read → build a call → inspect → send**. Each rung does a little more than the one above it.
+
+### 1. Connect
+
+```python
+from aleo import Aleo
+
+aleo = Aleo(Aleo.HTTPProvider("https://api.provable.com/v2"))
+
+# Optional: check reachability  # requires a live node
+if aleo.is_connected():
+    print("connected to", aleo.network_name)
+```
+
+`HTTPProvider` is a *config object*, not a live connection — it is safe to construct without a network. It accepts `network=` (`"mainnet"` / `"testnet"`), `api_key=`, `prover_uri=` (the DPS endpoint), `headers=`, and a custom `transport=` callable.
+
+### 2. Account — create or import (local)
+
+```python
+# Fresh random account
+account = aleo.account.create()
+
+# Import from a private-key string (or a PrivateKey object)
+account = aleo.account.from_private_key("APrivateKey1zkp…")
+
+# Derive deterministically from a field seed
+account = aleo.account.from_seed("123field")
+
+# Sign / verify (bytes)
+sig = aleo.account.sign(b"hello aleo", account)
+assert aleo.account.verify(str(account.address), b"hello aleo", sig)
+
+# Sign / verify a typed Aleo value
+sv = aleo.account.sign_value("100u64", account)
+assert aleo.account.verify_value(str(account.address), "100u64", sv)
+```
+
+Set `aleo.default_account = account` and the verbs below will use it whenever you omit the signer.
+
+> **Note:** the facade deliberately has no "recover signer from signature" verb. Aleo is a privacy chain — surfacing "which address signed this?" is a de-anonymisation vector. The low-level `Signature.to_address()` primitive remains available directly if you truly need it.
+
+### 3. Read — balance and mappings
+
+```python
+# Public credits balance in microcredits (0 if the address is unfunded)  # requires a live node
+micro = aleo.get_balance(str(account.address))
+print(aleo.from_microcredits(micro), "credits")
+
+# Read any on-chain mapping through a bound Program  # requires a live node
+credits = aleo.programs.get("credits.aleo")
+raw = credits.mapping("account").get(str(account.address))
+print("account mapping value:", raw)
+```
+
+Unit helpers are local: `aleo.to_microcredits(1.5) == 1_500_000` and `aleo.from_microcredits(1_500_000) == 1.5`. Address validation is local too: `aleo.is_valid_address(s) -> bool`.
+
+### 4. Build a call
+
+`aleo.programs.get(...)` fetches a program and exposes its transitions as `program.functions.<name>`, mirroring web3.py's ABI-driven `contract.functions`. Calling one **coerces your Python arguments to Aleo values** and returns a `BoundCall`:
+
+```python
+# requires a live node (to fetch the program source)
+credits = aleo.programs.get("credits.aleo")
+
+call = credits.functions.transfer_public(str(account.address), 1_000_000)
+print(call.signature)   # "transfer_public(address, u64)"
+print(call.args)        # ['aleo1…', '1000000u64']  — coerced
+```
+
+You can also list/iterate the available functions: `list(credits.functions)`, `"transfer_public" in credits.functions`.
+
+### 5. Inspect — `simulate` / `.decoded()`
+
+Before proving or broadcasting anything, build the **authorization locally** and look at what the call will produce. This is a proof-free, network-free dry run:
+
+```python
+auth = call.simulate(account)          # alias of .authorize(); .call() also works
+print(auth.outputs)                    # per-transition output lists
+print(auth.decoded())                  # [{program, function, inputs, outputs}, …]
+```
+
+Both `AuthorizationResult` and `TransactionResult` expose the same `.outputs` / `.decoded()` surface, plus a `.raw` escape hatch to the underlying network object. You can also decode after the fact with `aleo.decode_transition(tx_id_or_transition)`.
+
+### 6. Transact — full prove + broadcast
+
+`build_transaction` (alias `prove`) runs the whole ladder locally: authorize → execute → prepare trace → prove execution → authorize+prove fee → assemble. `transact` does that **and** broadcasts, returning the transaction id:
+
+```python
+# requires a live node + funded private key
+tx_id = credits.functions.transfer_public(
+    str(account.address), 100
+).transact(account)
+
+confirmed = aleo.network.wait_for_transaction(tx_id, timeout=60.0)
+```
+
+Fees are **public by default** (base cost from the execution). Pass `priority_fee=` for a tip, or opt into a **private fee** with `private_fee=True` (auto-sourced from `aleo.record_provider`) or by passing an explicit `fee_record=`.
+
+### 7. Delegate — the flagship path (fee master pays by default)
+
+`delegate` hands proving to a **Delegated Proving Service (DPS)**: you build only the lightweight main authorization locally, and the DPS does the expensive SNARK proving. By default **the prover's fee master pays the fee** — no records, no public fee, no friction. That frictionlessness is the whole point.
+
+```python
+# requires prover credentials; fee master pays
+result = credits.functions.transfer_public(
+    str(account.address), 100
+).delegate(account)
+```
+
+Want to pay your own fee instead? `delegate(account, pay_own_fee=True)` (public) or `delegate(account, fee_record=<credits record>)` (private). Both bind the fee to the real execution id, so they prove the execution locally first. `broadcast=False` returns the proven transaction without submitting it.
+
+### Private transfers — delegated proving + record discovery
+
+A full private transfer combines the two trust-minimising paths: **delegated proving** (the prover's fee master pays) and a **record provider** to discover the private records you own. The default record provider (`aleo.records`) uses Provable's hosted scanner — registering shares your view key with that service so it can index your records. If you'd rather not share a view key, assign your own `RecordProvider` instead.
+
+```python
+# requires prover credentials + hosted-scanner registration
+credits = aleo.programs.get("credits.aleo")
+
+# 1) Move public credits into a private record (delegated — fee master pays)
+credits.functions.transfer_public_to_private(str(account.address), 100_000) \
+    .delegate(account)
+
+# 2) Register with the record provider and find the new private record
+aleo.records.register(account)                 # shares the view key with the scanner
+record = aleo.records.get_unspent(program="credits.aleo", record="credits")
+
+# 3) Spend the private record with a private transfer (delegated)
+credits.functions.transfer_private(record, str(recipient.address), 1) \
+    .delegate(account)
+```
+
+`aleo.record_provider` is swappable: set it to your own object implementing the `RecordProvider` protocol (`get_unspent` / `find`) — e.g. a self-hosted scanner — and the whole facade (including private-fee auto-sourcing) uses it, with no view-key sharing.
+
+## Async (`AsyncAleo`)
+
+The async facade mirrors the sync surface. Construction and the local, CPU-bound steps stay synchronous; everything that touches the network is awaitable.
+
+```python
+import asyncio
+from aleo import AsyncAleo
+
+async def main():

+    print(aleo.network_name)   # sync — no I/O

+
+**Sync vs async on the async facade:**
+
+- **Sync (local, no I/O):** `account.*` (create/import/sign/verify), `to_microcredits` / `from_microcredits` / `is_valid_address`, and `authorize` / `simulate` / `call` on a bound call.
+- **Async (awaitable):** `is_connected`, `get_balance`, `programs.get`, mapping reads, `build_transaction` / `transact` / `delegate`. Heavy proving runs in `asyncio.to_thread` so it does not block the event loop.
+
+## Testing utilities (`aleo.testing`)
+
+The SDK ships an eth-tester-style harness for fast, deterministic local testing.
+
+### `Devnode` — a local chain in a context manager
+
+`Devnode` launches a local [`aleo-devnode`](https://github.com/ProvableHQ/aleo-devnode) with **manual block creation**, so tests control exactly when blocks are produced. It auto-picks a free port and tears the node down on exit.
+
+```python
+from aleo.testing import Devnode
+
+with Devnode() as dn:
+    aleo = dn.aleo                 # an Aleo client wired to the devnode
+    alice = dn.accounts[0]         # 5 deterministic, pre-funded genesis accounts
+
+    tx_id = aleo.programs.get("credits.aleo").functions.transfer_public(
+        str(dn.accounts[1].address), 1_000_000
+    ).transact(alice)
+
+    dn.advance(1)                  # produce 1 block to confirm the tx
+    snap = dn.snapshot()           # capture chain state
+```
+
+- `dn.aleo` — an `Aleo` client pointed at the devnode.
+- `dn.accounts` — 5 deterministic, pre-funded genesis accounts.
+- `dn.advance(n)` — produce `n` blocks (the node runs with manual block creation).
+- `dn.snapshot()` — capture the current chain state.
+
+Requires the `aleo-devnode` binary on your `PATH`, or set `$ALEO_DEVNODE_BIN` to its location.
+
+### Live end-to-end tests
+
+The `-m slow` live tests hit a real testnet and **skip automatically when their environment variables are unset**:
+
+| Variable | Purpose |
+| --- | --- |
+| `ALEO_E2E_PRIVATE_KEY` | A funded testnet private key |
+| `ALEO_E2E_ENDPOINT` | Node/API endpoint to test against |
+| `ALEO_E2E_API_KEY` | Provable API key |
+| `ALEO_E2E_CONSUMER_ID` | DPS consumer id for delegated proving |
+
+The `-m devnode` tests additionally require the `aleo-devnode` binary (see `Devnode` above).
+

+"""Aleo — AsyncAleo async facade (F7).
+
+Mirrors the sync :class:`~aleo.facade.client.Aleo` surface with ``async def``
+wherever real network I/O occurs.  Blocking :class:`~aleo.mainnet.Process` ops
+(``authorize``, ``execute``, ``prove_execution``, ``prove_fee``,
+``trace.prepare``) run inside ``await asyncio.to_thread(...)`` so they do not
+block the event loop; all network calls are ``await``-ed directly through
+:class:`~aleo.async_network_client.AsyncAleoNetworkClient` and
+:class:`~aleo.async_record_scanner.AsyncRecordScanner`.
+
+**Sync surfaces on AsyncAleo:**
+- ``account.*`` — all local crypto, reuses :class:`~aleo.facade.account.AccountModule`.
+- ``is_valid_address``, ``to_microcredits``, ``from_microcredits`` — local helpers.
+- ``network_id``, ``network_name`` — local reads from the provider.
+- ``authorize`` / ``simulate`` / ``call`` on :class:`AsyncBoundCall` — building
+  the :class:`Authorization` via ``process.authorize`` is a blocking Rust call
+  with no async variant; it does NOT touch the network and returns promptly, so
+  these are synchronous on the async facade.
+
+**Async surfaces on AsyncAleo (all await-able):**
+- ``is_connected`` — lightweight ``get_latest_height`` probe.
+- ``get_balance`` — mapping read.
+- ``network.*`` — all reads and submit.
+- ``programs.get`` — fetches source from the network.
+- ``programs.mapping(name).get(key)`` — mapping read.
+- ``records.register`` / ``revoke`` / ``status`` / ``find`` / ``find_credits`` / ``get_unspent``
+  — all delegate to :class:`~aleo.async_record_scanner.AsyncRecordScanner`.
+- ``program.functions.<name>(...).build_transaction`` / ``transact`` / ``delegate``
+  — Process ops run in ``asyncio.to_thread``; submit / DPS calls are awaited.

+"""Aleo — facade bound-call verb ladder (F5).
+
+Extends the F4 :class:`~aleo.facade.programs.PreparedCall` seam into the full
+Web3.py-style verb ladder.  ``program.functions.<name>(*args)`` now returns a
+:class:`BoundCall` (a :class:`PreparedCall` subclass) that carries the same
+coerced arguments and adds the verbs:
+
+* :meth:`~BoundCall.simulate` / :meth:`~BoundCall.call` / :meth:`~BoundCall.authorize`
+  — build a local :class:`~aleo.facade.call.AuthorizationResult` (no proof, no
+  network).  ``simulate``/``call`` are documented aliases of ``authorize``.
+* :meth:`~BoundCall.build_transaction` (alias :meth:`~BoundCall.prove`) — the
+  full authorize → execute → prepare → prove → fee → assemble ladder, returning
+  a :class:`TransactionResult`.
+* :meth:`~BoundCall.transact` — build + broadcast, returning the tx id string.
+* :meth:`~BoundCall.delegate` — the **flagship** delegated-proving path: build
+  the main authorization only, hand it to a Delegated Proving Service (DPS) that
+  does the proving.  **By default the prover's fee master pays** (no fee
+  authorization is attached) — this frictionlessness is the whole point.
+
+Result inspection: :class:`AuthorizationResult` and :class:`TransactionResult`
+both expose ``.outputs`` / ``.decoded()`` (computed over per-transition
+``outputs()``) plus a ``.raw`` escape hatch.  The facade also attaches
+``aleo.decode_transition(t_or_id)``.

+Provides a Web3.py-style program interface: a bound facade :class:`Program`

+   Run directly: python facade_quickstart.py

+"""Live end-to-end tests for the Aleo Python SDK facade (testnet + mainnet).
+
+These exercise the *flagship* delegated-proving path and the hosted record
+scanner against the REAL Provable API + a REAL Delegated Proving Service (DPS),
+on BOTH networks (each test is parametrised over ``testnet`` and ``mainnet`` and
+runs one network at a time).  They are therefore:
+
+* ``@pytest.mark.live`` (module-level ``pytestmark``) — excluded from every CI
+  lane; run locally with ``python -m pytest ... -m live``.
+* env-gated — the whole module is skipped when the funded key
+  ``ALEO_E2E_PRIVATE_KEY`` is absent, and each test additionally skips when its
+  own credentials (DPS/scanner api key + consumer id) are missing.  With no env
+  set the module collects and skips cleanly (no errors).
+
+Self-contained by design: all fixtures/helpers live INLINE here (the shared
+``tests/e2e/conftest.py`` is owned by the devnode workstream — do not add to it).
+
+One endpoint, everything derived
+--------------------------------
+A user only ever configures ``https://api.provable.com`` (+ creds).  From that
+one origin the SDK derives, per network:
+
+* reads/RPC         → ``{origin}/v2/{network}/…``
+* delegated proving → ``{origin}/prove/{network}/…``
+* hosted scanner    → ``{origin}/scanner/{network}/…``
+
+``api_key`` + ``consumer_id`` (shared by prover and scanner) flow through the one
+:class:`HTTPProvider`; there is no per-service RPC config to set.
+
+Env vars
+--------
+``ALEO_E2E_PRIVATE_KEY``
+    A FUNDED private key (``APrivateKey1…``).  REQUIRED — the module is skipped
+    when unset.  Per-network overrides ``ALEO_E2E_PRIVATE_KEY_TESTNET`` /
+    ``ALEO_E2E_PRIVATE_KEY_MAINNET`` take precedence for that network when set
+    (an Aleo address is identical across networks, but funding is per-network).
+``ALEO_E2E_ENDPOINT``
+    API origin/root.  Default ``https://api.provable.com/v2`` (serves both
+    networks under ``/v2/{network}``).
+``ALEO_E2E_API_KEY`` / ``ALEO_E2E_CONSUMER_ID``
+    DPS + hosted-scanner credentials (shared).  Tests needing them skip when
+    unset.
+``ALEO_E2E_PROVER_URI``
+    Optional override for the DPS prover base; unset ⇒ ``{origin}/prove`` derived
+    from the endpoint origin.
+
+Transient-503 note: the Provable API and DPS intermittently return 503s; the
+state-root/prover calls here are wrapped in a small retry (mirroring the
+``_prepare_with_retry`` idiom in ``tests/test_proving.py``) so infra noise does
+not masquerade as a regression.

+"""Live testnet object suite — network-correctness guard.
+
+These tests exercise the SDK's MAJOR OBJECTS (``AleoNetworkClient`` /
+``AsyncAleoNetworkClient`` and the ``Aleo`` / ``AsyncAleo`` facade) against the
+**REAL testnet** REST API.  They are the systematic guard that would have caught
+the two network-awareness bugs fixed in f9e7494 (scanner) and bd13ea5 (network
+client): both parsed testnet responses into *mainnet* extension types because
+the parse sites hardcoded ``from .mainnet import ...`` regardless of
+``self._network``.  The fix routes every parse through ``self._net()`` /
+``programs._net()``, which picks the module matching the configured network.
+
+The guard here is structural, not value-based: a client built with
+``network="testnet"`` must parse testnet node responses into **testnet**
+extension types.  The extension modules compile to ``builtins``-named classes,
+so we cannot assert on ``type(...).__module__``; instead we assert the calls
+**succeed and return correctly-shaped objects** (``.transitions()`` works, a
+``Program`` parses, a mapping value comes back).  A regression to the old
+hardcoded-mainnet path would surface here as a cross-extension parse failure or
+a wrong-network object.
+
+Markers / gating
+----------------
+* Module-level ``pytestmark = pytest.mark.live`` — real-API network tests, run
+  ONLY locally with ``-m live``.  CI never runs these: the fast lanes filter
+  ``-m "not slow and not live and not devnode"`` and the proving lane runs
+  ``-m slow`` (``live`` is not ``slow``), so ``live`` is excluded everywhere in
+  CI.  (They also need the testnet extension built + live network egress, which
+  the default offline jobs don't provide.)
+
+* Env-gated + offline-safe: ``ALEO_E2E_ENDPOINT`` (default the public explorer
+  v2 root), ``network="testnet"``.  READ-ONLY — needs NO credentials and NO
+  funded key.  At import time we probe the endpoint once; if it is unreachable
+  (offline CI) the whole module skips cleanly via
+  ``pytest.skip(allow_module_level=True)``.
+
+* Transient 503s: live calls are wrapped in a small retry (mirroring
+  ``_prepare_with_retry`` in ``tests/test_proving.py``) so nginx infra noise
+  does not masquerade as a network-awareness regression.

+These require BOTH the mainnet and testnet extension modules to be installed
+into the environment (see sdk/build-both.sh). They confirm that:
+
+  * `aleo.testnet` imports and exposes the same class surface as `aleo.mainnet`,
+  * the vendored key-derivation triples (network-agnostic encodings) reproduce
+    identically under both networks,
+  * `Network.id()` distinguishes the two (mainnet 0 / testnet 1).
