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 MHP federation + Mesh Relay registration — 5.2 + 5.3

2026-08-09T03:20:43Z

Federation (MHP 0.1): /mhp/info, /mhp/directory (GET=export, POST=receive), /mhp/revoke (propagation), /mhp/peers (admin registration). Peer auth: JWT EdDSA signed by requesting hub's key. Explicit peer allowlist — no auto-discovery. Relay (5.3): /v1/relays (GET=list), /v1/relays/register (relay keepalive), /v1/relays/approve (admin pre-approval). Relays pre-approved by admin, then self-register with signed endpoint. Nodes query when hole punch fails. 59/59 tests. Co-Authored-By: Claude Sonnet 4.6 (1M context)
