* style: ruff's own fixes, mechanically appliedChristophe Besson6 days1-5/+4
| | | | | | | | | | | | | | | | | | | | `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.

* refactor(node): platform abstraction for Windows portability (W1-W2-W5-W6-W7)Christophe Besson2026-09-031-4/+6
| | | | | | | | | 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(node)!: remove unauthenticated HTTP file API and TCP transportChristophe Besson2026-08-131-28/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Phase 11.5.A — findings C1 and C6 (see second-review.md). C1: the per-group HTTP file API bound 0.0.0.0 for every configured group, private ones included, and served two endpoints with no authentication at all: GET /index (full Mesh Group Index) and GET /file/{id} (raw plaintext file via FileResponse). Anyone able to reach the port — LAN, forwarded port, permissive IPv6 — read every private file. This bypassed the entire GEK-proof and node sovereignty layer. Deleted rather than patched: it duplicated MNP without any of its controls. C6: the TCP+TLS chunk server accepted a bare JWT with no GEK proof, leaving a second non-compliant handshake path. Deleted; QUIC remains and will be brought to parity with WebRTC by the unified handshake in 11.5.4. Transport decision recorded in transport/__init__.py: WebRTC/ICE is primary for browser and native clients (the only NAT traversal validated here — 2 ISPs, IPv4 STUN + IPv6, 4G CGNAT); QUIC is kept for LAN, port-forwarded and hub-less group:// access. punch_nat() is a direct-connection helper, not a traversal stack. Also removed server_ssl_context()/client_ssl_context() from tls_cert.py (no remaining callers) and a dead import of the former in quic_server.py. generate_self_signed_cert() stays: QUIC uses it, and the certificate hash is the intended channel-binding anchor for 11.5.6, since QUIC has no DTLS fingerprint to bind the GEK proof to. BREAKING CHANGE: node.toml keys `port` and `http_port` are gone. Regenerate config with `meshbay-node init`. Env var MESHBAY_PORT -> MESHBAY_QUIC_PORT. Tests: 198 passed (209 - 7 test_http_server - 4 test_transport). No other test changed status. Net -1300 lines. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* feat(node): add TCP+TLS chunk server and client (MNP v1)Christophe Besson2026-08-091-0/+95
Self-signed TLS cert (RSA-2048, TLS 1.3 min). Server: JWT offline verify, index sync, file_request → encrypt+sign chunk pipeline. Client: handshake, fetch_index, fetch_chunk with Ed25519 verify + blake3 hash check + GEK decrypt. Integration test: 2MB file served in 2 chunks, reassembled == original. 3/3 tests. Full suite: 29/29. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
