feat(server): wire device_id through delivery proto and v2 handlers
...
Add device_id field to FetchRequest, FetchWaitRequest, PeekRequest,
and AckRequest proto messages. V2 handlers now build composite
queue keys (identity_key + device_id) when device_id is provided,
enabling per-device fetch/ack scoping.

feat(server): v2 RPC handler dispatch for all 33 methods
...
Add v2_handlers module with ServerState, build_registry(), require_auth()
helper, and 33 protobuf handlers across 10 files:
- auth: 4 OPAQUE handlers (register start/finish, login start/finish)
- delivery: 6 handlers (enqueue, fetch, fetch_wait, peek, ack, batch)
- keys: 5 handlers (upload/fetch key package, upload/fetch hybrid key/keys)
- channel: create_channel
- user: resolve_user, resolve_identity
- blob: upload_blob, download_blob
- device: register, list, revoke
- p2p: publish_endpoint, resolve_endpoint, health
- federation: 6 stubs (Unimplemented)
- account: delete_account
All handlers decode protobuf, call domain services, encode response.
Auth handlers use full OPAQUE flow with session creation.
Delivery handlers include rate limiting and long-poll (fetch_wait).

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.

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.
