feat(federation): implement v2 inbound federation handlers
...
Replace stub federation handlers with full implementations that accept
relay and proxy requests from peer servers. Adds federation_client and
local_domain fields to ServerState for outbound relay and federated
address resolution. All six handlers (relay_enqueue, relay_batch_enqueue,
proxy_fetch_key_package, proxy_fetch_hybrid_key, proxy_resolve_user,
federation_health) now validate federation auth, interact with local
storage, and wake waiters on message delivery.

feat: add traffic analysis resistance (Phase 7.7 + F8)
...
- Core: add pad_uniform/unpad_uniform for configurable boundary padding
and generate_decoy for indistinguishable decoy messages
- Server: add traffic_resistance module with payload padding, timing
jitter, and background decoy traffic generator (feature-gated)
- P2P: add mesh traffic_resistance module with padded envelopes and
mesh decoy injection (feature-gated)
- All gated behind --features traffic-resistance
- 22 new tests across core (8), server (4), and P2P (5)

feat: implement account recovery with encrypted backup bundles
...
Add recovery code generation (8 codes per setup), Argon2id key derivation,
ChaCha20-Poly1305 encrypted bundles, and server-side zero-knowledge storage.
Each code independently recovers the account. Includes core crypto module,
protobuf service (method IDs 750-752), server domain + handlers, SDK methods,
SQL migration, and CLI commands (/recovery setup, /recovery restore).

fix: security hardening — 40 findings from full codebase review
...
Full codebase review by 4 independent agents (security, architecture,
code quality, correctness) identified ~80 findings. This commit fixes 40
of them across all workspace crates.
Critical fixes:
- Federation service: validate origin against mTLS cert CN/SAN (C1)
- WS bridge: add DM channel auth, size limits, rate limiting (C2)
- hpke_seal: panic on error instead of silent empty ciphertext (C3)
- hpke_setup_sender_and_export: error on parse fail, no PQ downgrade (C7)
Security fixes:
- Zeroize: seed_bytes() returns Zeroizing<[u8;32]>, private_to_bytes()
returns Zeroizing<Vec<u8>>, ClientAuth.access_token, SessionState.password,
conversation hex_key all wrapped in Zeroizing
- Keystore: 0o600 file permissions on Unix
- MeshIdentity: 0o600 file permissions on Unix
- Timing floors: resolveIdentity + WS bridge resolve_user get 5ms floor
- Mobile: TLS verification gated behind insecure-dev feature flag
- Proto: from_bytes default limit tightened from 64 MiB to 8 MiB
Correctness fixes:
- fetch_wait: register waiter before fetch to close TOCTOU window
- MeshEnvelope: exclude hop_count from signature (forwarding no longer
invalidates sender signature)
- BroadcastChannel: encrypt returns Result instead of panicking
- transcript: rename verify_transcript_chain → validate_transcript_structure
- group.rs: extract shared process_incoming() for receive_message variants
- auth_ops: remove spurious RegistrationRequest deserialization
- MeshStore.seen: bounded to 100K with FIFO eviction
Quality fixes:
- FFI error classification: typed downcast instead of string matching
- Plugin HookVTable: SAFETY documentation for unsafe Send+Sync
- clippy::unwrap_used: warn → deny workspace-wide
- Various .unwrap_or("") → proper error returns

feat: Sprint 10+11 — privacy hardening and multi-device support
...
Privacy Hardening (Sprint 10):
- Server --redact-logs flag: SHA-256 hashed identity prefixes in audit
logs, payload_len omitted when enabled
- Client /privacy command suite: redact-keys on|off, auto-clear with
duration parsing, padding on|off for traffic analysis resistance
- Forward secrecy: /verify-fs checks MLS epoch advancement,
/rotate-all-keys rotates MLS leaf + hybrid KEM keypair
- Dummy message type (0x09): constant-rate traffic padding every 30s,
silently discarded by recipients, serialize_dummy() + parse support
- delete_messages_before() for auto-clear in ConversationStore
Multi-Device Support (Sprint 11):
- Device registry: registerDevice @24, listDevices @25, revokeDevice @26
RPCs with Device struct (deviceId, deviceName, registeredAt)
- Server storage: devices table (migration 008), max 5 per identity,
E029_DEVICE_LIMIT and E030_DEVICE_NOT_FOUND error codes
- Device cleanup integrated into deleteAccount transaction
- Client REPL: /devices, /register-device <name>, /revoke-device <id>
72 core + 35 server tests pass.

feat: Sprint 6 — disappearing messages, group info, account deletion
...
- Disappearing messages: ttlSecs param on enqueue/batchEnqueue RPCs,
expires_at column (migration 007), server GC deletes expired messages,
/disappear command with human-friendly duration parsing (30m, 1h, 1d)
- Group info: /group-info shows type, members, MLS epoch; /rename
renames conversations; /members resolves usernames via resolveIdentity
- Account deletion: deleteAccount @23 RPC with transactional purge of
all user data (deliveries, keys, channels), session invalidation,
KT log preserved for auditability; /delete-account with confirmation
- Added epoch() accessor to GroupMember, enqueue_with_ttl client helper
All 35 server + 71 core + 14 E2E tests pass.

feat: Sprint 5 — encrypted file transfer with chunked upload/download
...
- Add uploadBlob (@21) and downloadBlob (@22) RPCs to Cap'n Proto
schema with SHA-256 content addressing and chunked transfer
- Server blob handler: 256KB chunks, SHA-256 verification on finalize,
.meta JSON sidecar, 50MB size limit, content-addressable storage
- Add FileRef (0x08) AppMessage variant with blob_id, filename,
file_size, mime_type
- /send-file command: read file, compute hash, upload in chunks with
progress display, send FileRef via MLS, MIME auto-detection
- /download command: fetch blob in chunks with progress, verify hash,
save to disk with collision avoidance
- 2 new E2E tests: upload/download round-trip with partial reads,
hash mismatch rejection (14 E2E tests total)
- New error codes: E024-E027 for blob operations

notification (loop-safe: only Chat/Reply trigger receipts)
- Typing indicators with /typing command, 10s timeout expiry,
/typing-notify toggle, ephemeral (not stored in DB)
- /react <emoji> [index] command for message reactions, display
inline with sender name
- Add Edit (0x06) and Delete (0x07) AppMessage variants with
serialize/parse, /edit and /delete REPL commands (own messages
only), incoming edit/delete handling with DB updates
- 3 new roundtrip tests for Edit/Delete serialization (70 core tests)

feat: DM epoch fix, federation relay, and mDNS mesh discovery
...
- schema: createChannel returns wasNew :Bool to elect the MLS initiator
unambiguously; prevents duplicate group creation on concurrent /dm calls
- core: group helpers for epoch tracking and key-package lifecycle
- server: federation subsystem — mTLS QUIC server-to-server relay with
Cap'n Proto RPC; enqueue/batchEnqueue relay unknown recipients to their
home domain via FederationClient
- server: mDNS _quicproquo._udp.local. service announcement on startup
- server: storage + sql_store — identity_exists, peek/ack, federation
home-server lookup helpers
- client: /mesh peers REPL command (mDNS discovery, feature = "mesh")
- client: MeshDiscovery — background mDNS browse with ServiceDaemon
- client: was_new=false path in cmd_dm waits for peer Welcome instead of
creating a duplicate initiator group
- p2p: fix ALPN from quicnprotochat/p2p/1 → quicproquo/p2p/1
- workspace: re-include quicproquo-p2p in members

- Binary names: quicnprotochat -> qpq, quicnprotochat-server -> qpq-server,
quicnprotochat-gui -> qpq-gui

*.db -> qpq.db
- Environment variable prefix: QUICNPROTOCHAT_* -> QPQ_*
- App identifier: chat.quicnproto.gui -> chat.quicproquo.gui
- Proto package: quicnprotochat.bench -> quicproquo.bench

HKDF domain-separation strings and P2P ALPN remain unchanged for
backward compatibility with existing encrypted state and wire protocol.
