The function was placed between the decorator and node_websocket,
breaking the WebSocket endpoint registration (403 on all WS connects).

Backend:
- Chat store persists sender_name (SQLite migration, no more UUID display)
- FILE_DELETE / FILE_DELETE_ACK MNP types — node admin can delete files
- Node sends chat_notify to hub WS — hub creates notifications for offline members
- Hub revocation.py handles chat_notify, creates per-member notifications
Frontend:
- Upload chunk size 64KB (was 1MB) — fixes WebRTC DataChannel max-message-size
- Show cached files immediately while WebRTC connects
- ChatImage component — inline image thumbnails in chat (download+decrypt)
- File delete action in menu (group admin, with confirm dialog)
- Member panel: "Owner" label instead of confusing "Group admin"
- Create group page: hint about needing a node
- Refresh index after chat attachment upload

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.

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).

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.

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.

Hub: /v1/nodes/ws WebSocket endpoint for persistent node connections.
/v1/admin/revoke marks user/group revoked in DB, signs JWT revocation
token (EdDSA), broadcasts to all connected nodes.
Node: RevocationSubscriber maintains WS connection, verifies
incoming revocation tokens offline (hub Ed25519 PK), adds to
local blocklist (_revoked_users/_revoked_groups sets).
53/53 tests.
