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 — 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(hub): Phase 8 — Hub v2 security hardening + production readiness

2026-08-10T01:57:55Z

8.1 Config-based admin authz (require_admin on all admin endpoints) 8.2 Email encrypted at rest (AES-256-GCM, HKDF from hub Ed25519 key) 8.3 Refresh token rotation with family-based reuse detection 8.4 Federation persistence (HubPeer model replaces in-memory dict) 8.5 Federation token verification now async (DB-backed) 8.6 CSAM hash check wired into swarm registration flow 8.7 Rate limiting on auth endpoints (5/10/20 per minute) 8.8 Healthcheck endpoint (GET /v1/health, no auth) 8.9 IP log cleanup background task (365-day retention) 8.10 Argon2id params bumped to 256 MB (pw_version, rehash on login) Deployed to meshbay.org — schema migrated, existing emails encrypted. 117 tests pass (29 hub, 88 common+node). Resolves security review items S1, S2, S5. Co-Authored-By: Claude Opus 4.6

feat: Phase 6 complete — chat, multi-group, federation, replication, webcrypto

2026-08-09T03:31:05Z

6.1 Double Ratchet (meshbay_common/ratchet.py): Forward secrecy, break-in recovery, out-of-order delivery. Signal-spec KDF_RK/KDF_CK via HKDF-SHA256. 11/11 tests. 6.2 Multi-group node (config.py): [[groups]] TOML array, per-group ports, back-compat [group]. 6.3 MHP federation persistence (db/models.py FederatedGroup + SwarmSource): receive_directory() now persists to federated_groups table. list_public_groups() includes federated results with source attribution. 6.4 Content replication (node/replication.py + hub SwarmSource): ContentReplicator: fetch-index, download, hash-verify, register-swarm. Hub: POST /v1/swarm/register, GET /v1/swarm/{hash} for multi-source. 6.5 Browser private group (webcrypto.py + static/crypto.js): AES-256-GCM variant of GEK for WebCrypto-compatible groups. crypto.js: SubtleCrypto importGEK + deriveChunkKey + decryptChunk. Keys distinct from ChaCha20 via :aes HKDF info suffix. 4/4 tests. 74/74 tests total. Co-Authored-By: Claude Sonnet 4.6 (1M context)

feat(hub): add web app + public group listing endpoint

2026-08-09T02:58:06Z

webapp.py: serves / (HTML SPA) and /app.js (JS client). app.js: login, hub API calls, node HTTP API integration, file browser, HLS video streaming via tag. groups.py: GET /v1/groups — public group listing (no auth). Deployed on https://meshbay.org — 200 OK. 47/47 tests. Co-Authored-By: Claude Sonnet 4.6 (1M context)

feat(hub): add production hub — config, auth, API routers, tests

2026-08-09T02:39:34Z

config.py: TOML + env var priority. auth.py: Argon2id passwords, JWT EdDSA with jti, refresh token hashed (blake3). Routers: hub (info/pubkey), users (register/login/refresh/pubkeys), nodes (announce/get), groups (create/gek-bundle/gek-retrieve). Rate limiting via slowapi. app.py factory with lifespan. All 40 tests pass (SQLite in-memory, no PostgreSQL required). Fix: remove tests/__init__.py to resolve namespace conflicts. Co-Authored-By: Claude Sonnet 4.6 (1M context)
