feat: Phase 12 — P2P crypto material, password split, node Ed25519 auth

2026-08-13T01:56:30Z

Baseline commit capturing in-progress Phase 12 work that was already present in the working tree (uncommitted) before the Phase 11.5 security remediation begins. Committed as-is, without review or modification, so that remediation changes arrive as a separable diff. Contents: BundleStore (P2P GEK + keypair bundles), password split (auth_key / bundle_key), node Ed25519 auth (POST /v1/nodes/auth, node-scoped JWT), GEK-HMAC handshake proof with DTLS channel binding, Ed25519 admin challenge-response, node local admin UI rewrite, browser key persistence. Not authored in this session — captured to establish a baseline. Co-Authored-By: Claude Opus 5

feat(node): index push to WebRTC peers + swarm registration (11.5, 11.9)

2026-08-11T20:16:59Z

When watchdog detects file changes, the daemon now: - Pushes INDEX_SYNC to all connected WebRTC peers in that group - Registers file hashes with hub /v1/swarm/register endpoint Also registers all file hashes on startup for initial discovery. hub_client: add register_swarm() method for bulk hash registration.

feat(node): Phase 11 — production-ready daemon with WebRTC, WS, chat, HTTP

2026-08-11T20:11:18Z

The node daemon was previously a skeleton that only started QUIC/TCP servers and the local web UI. All browser-facing functionality (WebRTC, hub WebSocket, chat store, HTTP file API) lived in QE demo scripts. This rewrites daemon.py to be fully self-contained: - WebRTC transport for browser clients (aiortc DataChannel) - Hub WebSocket task (signaling, revocations, WebRTC offers) - ChatStore per group (SQLite in ~/.local/share/meshbay/) - HTTP file API per group (create_http_app on configured port) - Graceful shutdown (all transports, stores, tasks) - hub_client: _ws tracking + send_ws() for chat notifications - config: data_dir field for persistent state - systemd: security hardening (ProtectSystem, StateDirectory) Co-Authored-By: Claude Opus 4.6

feat: Phase 9 — Web client SPA with WebRTC P2P transport

2026-08-11T02:13:53Z

Complete browser-based client: Preact SPA with login, group file browser, encrypted download, video playback, group chat, i18n, and dark/light theme. Browser connects P2P to nodes behind residential NAT via WebRTC DataChannel (aiortc). Hub handles signaling only — all data flows E2E. Performance: pipelined downloads (8-chunk sliding window), binary msgpack wire format (no base64), redundant I/O elimination. Large file downloads stream to disk via File System Access API (showSaveFilePicker). Validated on SFR + Orange residential NATs, Chrome + Firefox, IPv4/IPv6. 132 tests passing. Deployed to meshbay.org + Orange node. Co-Authored-By: Claude Opus 4.6

feat: Phase 9.1–9.5 — WebRTC DataChannel transport for browser P2P

2026-08-10T20:12:59Z

Browser clients can now connect P2P to nodes behind residential NAT via WebRTC DataChannel with ICE/STUN. Validated on SFR Port-Restricted Cone NAT + 4G CGNAT across three scenarios (WiFi LAN, 4G IPv6, 4G IPv4 STUN). No TURN relay needed. Hub serves only as signaling relay (<1 KB). New files: - webrtc_server.py: aiortc-based WebRTC transport (node side) - signaling.py: SDP/ICE relay endpoint (hub side) - transport.js: browser WebRTC client with msgpack framing - webrtc-test.html: spike test page for browser→NAT→node validation - test_webrtc_transport.py: 4 tests (handshake, file transfer, auth, guard) - meshbay-draft-v4.md: architecture spec updated for web client Modified: - hub_client.py: WebRTC offer handling via hub WebSocket - revocation.py: node_id from WS auth + webrtc_answer routing - pyproject.toml: aiortc>=1.9 dependency 123 tests passing (117 existing + 6 new).

feat: Phase 7 — Node v2 (multi-group, Sender Keys, 0-RTT, chat, denylist)

2026-08-10T01:07:56Z

Implements all 8 milestones (7.0-7.7): - 7.0: JWT carries `groups` claim; node verifies group membership at MNP handshake (QUIC + TCP+TLS). Resolves security review C2. - 7.1: QUIC 0-RTT session resumption via stored session tickets (17-21ms reconnect vs 47ms cold). - 7.2: Hub→node WebSocket signaling for NAT punch coordination (`client_incoming`/`punch_ready`) + jti denylist push. Denylist class blocks revoked users/jtis at handshake. - 7.3: Multi-group daemon — one QUIC port serves N groups with per-group GEK, shared_root, and index routing. - 7.4: HLS streaming via QUIC (STREAM_SEGMENT message type, ffmpeg segment extraction). - 7.5: Sender Keys protocol for group chat (Signal Groups approach). Each member has own sending chain key, HKDF chain ratchet, AES-256-GCM encryption, Ed25519 signing. Resolves security review C1. - 7.6: Chat store (SQLite via aiosqlite), CHAT_MESSAGE MNP wire type with peer broadcast, web UI with WebSocket push. - 7.7: Argon2id calibration CLI. First security review included (first-review.md). 109 tests, demo-v3 validated against meshbay.org production hub. Co-Authored-By: Claude Opus 4.6

feat(node): add hub client with JWT offline verify and GEK fetch

2026-08-09T02:06:46Z

Register/login/announce/token-refresh/GEK-unwrap. JWT jti and pk_user verified at login. Hub PK cached after first fetch. 6/6 tests passing with httpx.MockTransport (no network). Co-Authored-By: Claude Sonnet 4.6 (1M context)
