From 82dd06dbe054d0829049728a9d12c34c93327159 Mon Sep 17 00:00:00 2001 From: Michael Turner Date: Fri, 10 Jul 2026 08:24:38 -0400 Subject: [PATCH 01/39] feat(sdk): restore testnet bundle dropped from squashed PR #44 PR #44 was squash-merged to master without the testnet work (testnet.py, _aleolib_testnet.pyi, build-both.sh, merge_testnet_so.py, AGENTS.md, the network-aware client changes). This restores that bundle on top of master so the two-build (mainnet+testnet) packaging ships, matching the migration branch tip e897fd1.

make AleoError a true base so 'except AleoError' catches all Move AleoError into _client_common (lowest layer); AleoNetworkError, AleoProvingError, and the RecordScanner errors now subclass it. Existing 'except AleoNetworkError' sites are unaffected (still subclasses). Corrects the F1 review finding that the internal errors were siblings, not subclasses, silently breaking the documented single-except contract; fixes the false 'conversion helpers' comment. is_connected keeps a broad catch (reachability probe, web3.py semantics).

Build a call + +`aleo.programs.get(...)` fetches a program and exposes its transitions as `program.functions.`, mirroring web3.py's ABI-driven `contract.functions`.

HTTPProvider gains a consumer_id field; api_key + consumer_id flow through the one provider to BOTH the delegated prover and the hosted scanner, so a user configures only https://api.provable.com — reads, proving, and scanning all derive from its origin. The scanner's own /pubkey→register/encrypted handshake keeps affinity via its requests.Session / httpx.AsyncClient cookie jar. Live e2e (tests/e2e/test_live_e2e.py, renamed from test_testnet_e2e.py) is now parametrised over testnet AND mainnet (one at a time).

So every delegate() mints a prover JWT that invalidates the scanner's cached JWT out-of-band (and vice versa). The clients only refreshed on the 5-minute expiry clock, so they never recovered — the next scanner query failed with "No credentials found for given 'iss'" and the next delegate failed with "pubkey: 401", even though registration/the mint had succeeded. Fix: on an auth failure (401/403, or a body reading "No credentials found for given 'iss'"), drop the cached JWT and retry the request ONCE with a freshly minted JWT — in the scanner (owned/register/get/post) and the prover (pubkey + prove handshake), sync and async. Each service self-heals when the other rotated the shared consumer's active token. Verified live on testnet: register → query → delegate → query → delegate → query all succeed (previously the 2nd query and 2nd delegate failed). Adds sync unit tests for both the prover and scanner refresh-on-401 paths.
