* style: ruff's own fixes, mechanically appliedChristophe Besson6 days1-4/+2
| | | | | | | | | | | | | | | | | | | | `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.

* fix(node): pin utf-8 (and LF) on every text file the node reads or writesChristophe Besson2026-09-041-3/+3
| | | | | | | | | | | | | | | node.toml, the keystore envelope, the unlock key, the loopback UI token, pairing/invite code files and the denylist were all read and written with the platform default encoding and newline translation. On Windows that is cp1252 + CRLF: a node.toml or keystore holding any non-ASCII byte failed to load, and ops.py's line-based node.toml editor round-tripped CRLF in and LF out. Every read is now `encoding="utf-8"`; every write is `encoding="utf-8", newline="\n"` so the files stay LF whatever the OS. No-op where the locale was already UTF-8.

* refactor(node): platform abstraction for Windows portability (W1-W2-W5-W6-W7)Christophe Besson2026-09-031-9/+13
| | | | | | | | | Platform directories, signal handling, chmod guards, ffmpeg discovery, and platform-conditional CLI messages — all testable on Linux. See docs/WINDOWS-PORT.md §5 for the plan these implement. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: swarm privacy, revocation persistence, keystore KDF, audit integrityChristophe Besson2026-08-131-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Phase 11.5 hardening batch — H7, H4, M2, M6, M7, L1, L3, L6. H7 — private content hashes leaked to the hub. The daemon registered blake3 hashes for every group it hosted, private ones included, giving the hub a content fingerprint of every private file and letting anyone confirm whether a known file exists in the network. The leak was dormant only because the routes were declared on the groups router with a full path and mounted at /v1/groups/v1/swarm/* — the node's calls 404'd into a swallowed exception. Fixing the path alone would have activated the leak, so both land together: registration is gated on group visibility, the routes moved to a real /v1/swarm router, and the lookup now requires authentication. H4 — revocation was advisory. Group revocations were signed and broadcast by the hub and then dropped by the node, whose handler understood only "user" and "jti", so "suspend a group" enforced nothing. The denylist was also in-memory only, so a restart silently un-revoked everyone. Now persisted to data_dir/denylist.json, group targets honoured on both transports, and live sessions for a revoked group are closed. M2 — the node keystore, which protects the node's Ed25519 and X25519 private keys, was still deriving at 64 MB long after the hub's password verifier moved to 256 MB; the docs recorded the bump as done, true for the hub only. Raising the constant alone would have made every existing keystore permanently undecryptable, so envelopes now record the parameters they were written with and pre-M2 files continue to open under the legacy profile. M6 — registration inserted its audit row with a NULL user_id and then ran UPDATE ip_logs SET user_id=<new> WHERE user_id IS NULL, claiming every unattributed row in the table: failed logins for other usernames, concurrent registrations. In logs retained a year for legal requests, that attributed other people's connections to the wrong account. M7 — X-Forwarded-For was trusted unconditionally at four call sites, so anyone could forge the IP written to the compliance log and evade per-IP rate limits. New netutil.client_ip honours the header only from a trusted proxy and takes the rightmost hop (the one our proxy appended); no direct header reads remain. L1 dead GEK_REQUEST/GEK_RESPONSE constants removed; L3 peer errors no longer echo exception text (paths, internal state); L6 email sanity-checked instead of accepting any string — deliberately not RFC 5322, to avoid a new dependency. test_daemon_index_change_pushes_to_peers asserted that a PRIVATE group's hashes are registered with the hub. Split: private asserts not-called (index push to members still asserted), and a new test proves public groups still register. That is the fourth pre-existing test found asserting a vulnerability as intended behaviour, after gek auto-activation, the transport-wide chat_store and the blind admin challenge. Tests: 116 node, 132 hub+common. Regression suite now 43. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* feat(node): add keystore module with 3 unlock modesChristophe Besson2026-08-091-0/+225
Argon2id + AES-256-GCM encryption at rest. Unlock via env var (MESHBAY_UNLOCK_KEY), unlock.key file (chmod 600), or interactive getpass. 10/10 tests passing. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
