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: Phase 10b — Self-service UI (group create/join, upload, IndexedDB, search)

2026-08-11T12:55:52Z

Six self-service features for the web SPA: - Group creation UI with GEK auto-generation (AES-256-GCM ECIES) - Member management + invite by username (GEK wrapping for invitee) - Open group self-join flow (POST /v1/groups/{id}/join) - File upload client→node (FILE_UPLOAD MNP type, .uploads/ staging) - IndexedDB caching of group file indexes (instant display on revisit) - Cross-group file search (SearchPage, pure client-side on cached indexes) 11 new tests (166 total): 8 group self-service + 3 AES GEK wrap/unwrap.

feat(hub): Phase 10.5–10.8, 10.10 — notifications, settings, search, version

2026-08-11T10:40:13Z

- 10.5: Notification model + CRUD API (list, mark read, mark all read) Triggered on: group invite, role change, suspend/unsuspend - 10.6: SettingsPage shows role, per-group notification mute (localStorage) - 10.7: GET /v1/groups?q= search filter (ilike on name) - 10.8: NotificationFeed on home page + bell with unread badge in navbar - 10.10: GET /v1/hub/version endpoint for client update checks - 8 new tests (test_notifications.py), 155 total 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

docs: update draft v3 + phases-next with Phase 7 decisions

2026-08-09T23:24:40Z

Multi-group: single QUIC port (multiplexing), group_id from JWT. Signaling punch/connect: hub WS client_incoming/punch_ready protocol, reduces handshake 12.7s → < 200ms. SFR Port-Restricted findings added. Chat model: between forum and Signal — persistent, threaded, E2E, per-group scope, push for online / pull for offline members.

fix: 4 corrections — streaming hash, watchdog bug, cipher doc, deps

2026-08-09T20:56:18Z

1. indexer.py: streaming blake3 (8MB chunks) instead of read_bytes(). Large files (initrd.img, ISOs, VM images) no longer load into RAM. 2. QE/demo-v1/run_node.py: call indexer.start() not initial_scan(). initial_scan() alone never starts the watchdog observer — files added after startup were silently ignored. Added indexer.stop() on shutdown. 3. USERGUIDE.md §8: clarify symmetric vs asymmetric. Ed25519/X25519 = asymmetric (key pairs). ChaCha20-Poly1305 and AES-256-GCM = symmetric AEAD 256-bit (content encryption). ChaCha20 is PRIMARY; AES-GCM is optional browser-compat variant only. 4. pyproject.toml: aioquic, websockets, aiosqlite, slowapi added to proper package deps (were installed manually, now declared).

fix: complete pyproject.toml deps + graceful QUIC fallback

2026-08-09T20:28:47Z

meshbay-node/pyproject.toml: add aioquic>=1.0 (was commented 'v2'), websockets>=12.0 (revocation push). Both are production code since Phase 5. meshbay-hub/pyproject.toml: add aiosqlite (tests without PostgreSQL), slowapi (rate limiting), websockets (revocation push), PyJWT (explicit). transport/__init__.py: QUIC imports wrapped in try/except — node works without aioquic (TCP+TLS + HTTP fallback). QUIC_AVAILABLE flag exported. QUICKSTART.md: replace manual pip list with 'pip install -e' that pulls all deps from pyproject.toml automatically. Add dependency table. CLAUDE.md: clarify that all deps go in pyproject.toml, not manual installs. 81/81 tests. Co-Authored-By: Claude Sonnet 4.6 (1M context)

fix: venv --clear required when copying repo across OS (Fedora→Ubuntu)

2026-08-09T19:55:12Z

Root cause: certifi.where() in the Fedora venv points to /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem which does not exist on Ubuntu. 'python3 -m venv .venv' without --clear keeps the Fedora certifi paths. Fix: always use --clear when recreating a venv on a different OS. Documented in QUICKSTART.md and CLAUDE.md. rsync command updated to exclude .venv/ (in QE/server-state, not versioned). Co-Authored-By: Claude Sonnet 4.6 (1M context)
