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.

docs: update all pointers after keyderive + QE restructure

2026-08-09T12:57:01Z

CLAUDE.md: add QE/ to structure, key modules table, server state reference, security rule updated (QE/ not keypair files), meshbay.org inventory pointer. devel-phases.md: add milestones 6.6-6.9 (keyderive, bundle, demo scripts, QUICKSTART rewrite). 81/81 tests. docs/meshbay-draft-v3.md §6.1.1: new section documenting 3 key generation strategies (Argon2id CLI, WebCrypto browser+bundle, keystore file) and the algorithm mismatch caveat between CLI and web registration paths. docs/USERGUIDE.md §2 Register+Login: replace "generate and persist before registering" warning with the two clean strategies (derive_keys_from_password for CLI, keyderive.js + keypair_bundle for browser). Login response updated with keypair_bundle field. hub/models.py + users.py + Alembic migration: keypair_bundle column on User, stored at registration, returned at login (web clients only).

docs: add architecture draft v3 with POC findings

2026-08-09T01:58:52Z

Key corrections from spikes 1-6: - JWT jti now required (prevents replay, enables revocation) - Argon2id params updated to target 500ms (256MB memory) - NAT order corrected: STUN before UPnP (UPnP unreliable on SFR) - Transport: TCP+TLS v1, QUIC v2 - GEK wrapping protocol confirmed (ECIES-like, 48B opaque bundle) - Hub API table complete with Spike 6 endpoints - 3-package monorepo structure documented Co-Authored-By: Claude Sonnet 4.6 (1M context)
