meshbay.git/packages/meshbay-common/src/meshbay_common/webcrypto.py, branch mainMeshBay — read-only public mirrorhttps://git.meshbay.org/meshbay.git/atom?h=main2026-09-19T12:24:13Zstyle: ruff's own fixes, mechanically applied2026-09-19T12:24:13ZChristophe Bessoncbesson@gmail.com2026-09-19T12:24:13Zurn:sha1:86188385cbdae1ee90c1dca7a7b9db2edef1ecd4
`ruff check .` had gone unrun long enough to report 568 errors, which is the
same as having no linter: the next real finding would have been invisible in the
noise. This is the 521 it fixes by itself, in 173 files, and nothing else — the
98 it cannot fix are the next commit.
What actually changed: import sorting (225), imports nobody used (87, none of
them a re-export — no `__init__.py` is touched, which was the one way this could
have broken an import elsewhere), `datetime.timezone.utc` to `datetime.UTC` (69)
and `asyncio.TimeoutError` to `TimeoutError` (18), both plain aliases on the 3.12
this project requires, `Optional[X]` to `X | None` (24), and f-strings with
nothing to interpolate (19).
Checked rather than assumed: every module in the three packages still imports,
and the suite is 2893 passed — the same count, test for test, as the merge
before it.

feat: Phase 6 complete — chat, multi-group, federation, replication, webcrypto2026-08-09T03:31:05ZChristophe Bessoncbesson@gmail.com2026-08-09T03:31:05Zurn:sha1:3b2dd318477eb268e6821fb000aeadfe60d85987
6.1 Double Ratchet (meshbay_common/ratchet.py):
Forward secrecy, break-in recovery, out-of-order delivery.
Signal-spec KDF_RK/KDF_CK via HKDF-SHA256. 11/11 tests.
6.2 Multi-group node (config.py):
[[groups]] TOML array, per-group ports, back-compat [group].
6.3 MHP federation persistence (db/models.py FederatedGroup + SwarmSource):
receive_directory() now persists to federated_groups table.
list_public_groups() includes federated results with source attribution.
6.4 Content replication (node/replication.py + hub SwarmSource):
ContentReplicator: fetch-index, download, hash-verify, register-swarm.
Hub: POST /v1/swarm/register, GET /v1/swarm/{hash} for multi-source.
6.5 Browser private group (webcrypto.py + static/crypto.js):
AES-256-GCM variant of GEK for WebCrypto-compatible groups.
crypto.js: SubtleCrypto importGEK + deriveChunkKey + decryptChunk.
Keys distinct from ChaCha20 via :aes HKDF info suffix. 4/4 tests.
74/74 tests total.
