* feat(node): audit logging + local admin UI rewriteChristophe Besson2026-08-111-0/+17
| | | | | | | | | | | | | | | | | | | Add SQLite audit store for legal compliance (LCEN/DSA): logs user IP, actions (handshake, file download/upload/delete, stream, chat), and timestamps. Retention: 1 year, with cleanup method. WebRTC transport now logs all user actions to the audit store with remote IP extraction from the ICE transport. Local web UI rewritten as a proper admin dashboard: - Stats cards (groups, files, peers) - Connected peers table with IP, username, group, state - Group cards with file listings and shared directory info - Audit log page with event/user filtering - Dark theme, responsive, auto-refresh - JSON API: /api/status, /api/groups, /api/peers, /api/audit, /api/config Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat(node): index push to WebRTC peers + swarm registration (11.5, 11.9)Christophe Besson2026-08-111-1/+59
| | | | | | | | | | | 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, HTTPChristophe Besson2026-08-111-28/+186
| | | | | | | | | | | | | | | | | | 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 <noreply@anthropic.com>
* feat: Phase 7 — Node v2 (multi-group, Sender Keys, 0-RTT, chat, denylist)Christophe Besson2026-08-101-40/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <noreply@anthropic.com>
* feat(node): add config, daemon, and local web UIChristophe Besson2026-08-091-2/+217
| | | | | | | | | | | config.py: TOML + env var overrides, sane defaults. daemon.py: full startup sequence (keystore→hub→GEK→indexer→ server→UI), SIGINT/SIGTERM shutdown, calibrate-argon2 command. ui/app.py: FastAPI on localhost:18000, status+files JSON API, HTML status page (auto-refresh 10s). All bound to 127.0.0.1. Full suite: 29/29 tests. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
* chore: initialize monorepo structure for MeshBayChristophe Besson2026-08-091-0/+9
3-package layout: meshbay-common (shared crypto/protocol), meshbay-hub (FastAPI server), meshbay-node (local daemon). Includes validated POC spikes 1-6 in poc/, architecture drafts v1/v2 in docs/, and CLAUDE.md project conventions. All cryptographic primitives extracted from POC into meshbay_common/crypto.py (GEK wrap/unwrap, chunk key derivation, keystore encryption, chunk signing).
