feat(client): v2 REPL over SDK with categorized help and tab-completion
...
925-line REPL replacing the 3317-line monolith — delegates all crypto,
MLS, and RPC to quicproquo-sdk. 20 commands across 6 categories
(messaging, groups, account, keys, utility, debug), rustyline tab
completion, background event listener, auto-server-launch.
Also adds SDK accessor methods (server_addr_string, config_state_path),
WS bridge register handler, and README table formatting cleanup.

feat(client): ratatui TUI subscribing to SDK events
...
Single-file v2 TUI (v2_tui.rs, ~580 lines) gated behind
cfg(all(feature = "v2", feature = "tui")).
Layout: conversations sidebar, scrollable messages panel,
input bar with cursor editing, status line. Help overlay
on /help. Subscribes to SDK broadcast::Receiver<ClientEvent>
for real-time updates. TerminalGuard ensures terminal restore
on panic. Commands: /login, /register, /logout, /dm, /group,
/quit, /help.
Build: cargo build -p quicproquo-client --features v2,tui

feat(client): v2 CLI binary over SDK with simplified commands
...
Add v2_main.rs and v2_commands.rs as thin wrappers over QpqClient from
quicproquo-sdk. Activated via --features v2 (feature-gated so v1 main.rs
remains the default). Includes auto-server-launch, clap-based command
surface (register-user, login, whoami, health, resolve, dm, group,
devices), and ClientConfig-based connection setup. MLS-dependent commands
(send, recv, group create/invite) print stubs pointing to the REPL.

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: 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

When no server is reachable, the REPL now automatically spawns a
qpq-server child process with dev defaults (--allow-insecure-auth,
matching TLS cert paths). The server is killed on REPL exit via a
Drop guard. Use --no-server to opt out (e.g. for remote servers).

feat: interactive REPL with auto-setup, auto-join, encrypted local storage
...
REPL auto-setup (zero-friction startup):
- OnceLock → RwLock for CLIENT_AUTH to allow delayed init after OPAQUE login
- Extract opaque_register/opaque_login helpers from one-shot commands
- Token cache (.session file) with QPCE encryption when password provided
- Add --username/--password/--state-password to repl subcommand
- resolve_access_token: auto-register + login, cache token, prompt interactively
- rpassword for secure password input (no echo)
Interactive REPL (multi-conversation):
- SessionState: identity, hybrid key, ConversationStore, per-conversation GroupMembers
- ConversationStore: SQLite-backed conversations + messages with full CRUD
- Slash commands: /dm, /group, /invite, /join, /switch, /list, /members, /history, /whoami
- Background polling (1s interval) with auto-join from MLS Welcome messages
- pending_member pattern: persistent keystore for HPKE init key, replenish after join
- Self-DM handled as local-only notepad (no MLS/server channel)
- ANSI display module for colored prompts, incoming messages, status/error output
Username resolution:
- resolveIdentity RPC (@20 in node.capnp): look up username by identity key
- Server: resolve_identity_key in Store trait, FileBackedStore, SqlStore
- Client: resolve_identity in rpc.rs, used in auto-join for peer display names
- resolveUser: bidirectional lookup (username → identity key)
Encrypted local storage (nothing in cleartext):
- ConversationStore uses SQLCipher when --state-password is provided
- Argon2id key derivation with per-database random salt (.convdb-salt, mode 0600)
- Transparent migration of existing unencrypted databases via sqlcipher_export
- Token cache encrypted with QPCE format (Argon2id + ChaCha20Poly1305)
Server changes:
- resolveIdentity + resolveUser RPC handlers with auth + validation
- Auth: sealed-sender identity binding on enqueue, channel member authorization
- Delivery: hybrid decrypt attempts, identity key validation on enqueue
- Config: --allow-sealed-sender flag for anonymous delivery mode
- zeroize added to server dependencies

chore: exclude p2p crate from workspace, slim tokio features
...
Move quicnprotochat-p2p to workspace.exclude so ~90 iroh-only
dependencies are not compiled in the default build. Narrow tokio
features from "full" to the subset actually used. The p2p crate
now pins its own dependency versions since it is outside the workspace.

DM channels (createChannel), channel authz, security/docs, future improvements
...
- Add createChannel RPC (node.capnp @18): create 1:1 channel, returns 16-byte channelId
- Store: create_channel(member_a, member_b), get_channel_members(channel_id)
- FileBackedStore: channels.bin; SqlStore: migration 003_channels, schema v4
- channel_ops: handle_create_channel (auth + identity, peerKey 32 bytes)
- Delivery authz: when channel_id.len() == 16, require caller and recipient are channel members (E022/E023)
- Error codes E022 CHANNEL_ACCESS_DENIED, E023 CHANNEL_NOT_FOUND
- SUMMARY: link Certificate lifecycle; security audit, future improvements, multi-agent plan docs
- Certificate lifecycle doc, SECURITY-AUDIT, FUTURE-IMPROVEMENTS, MULTI-AGENT-WORK-PLAN
- Client/core/tls/auth/server main: assorted fixes and updates from review and audit

feat: add delivery sequence numbers + major server/client refactor
...
Delivery sequence numbers (MLS epoch ordering fix):
- schemas/node.capnp: add Envelope{seq,data} struct; enqueue returns seq:UInt64;
fetch/fetchWait return List(Envelope) instead of List(Data)
- storage.rs: Store trait enqueue returns u64; fetch/fetch_limited return
Vec<(u64, Vec<u8>)>; FileBackedStore gains QueueMapV3 with per-inbox seq
counters and V2→V3 on-disk migration
- migrations/002_add_seq.sql: seq column, delivery_seq_counters table, index
- sql_store.rs: atomic UPSERT counter via RETURNING, ORDER BY seq, SCHEMA_VERSION→3
- node_service/delivery.rs: builds Envelope list; returns seq from enqueue
- client/rpc.rs: enqueue→u64, fetch_all/fetch_wait→Vec<(u64,Vec<u8>)>
- client/commands.rs: sort-by-seq before MLS processing; retry loop in cmd_recv
and receive_pending_plaintexts for correct epoch ordering
Server refactor:
- Split monolithic main.rs into node_service/{mod,delivery,auth_ops,key_ops,p2p_ops}
- Add auth.rs (token validation, rate limiting), config.rs, metrics.rs, tls.rs
- Add SQL migrations runner (001_initial.sql, 002_add_seq.sql)
- OPAQUE PAKE login/registration, sealed-sender mode, queue depth limit (1000)
Client refactor:
- Split lib.rs into client/{commands,rpc,state,retry,hex,mod}
- Add cmd_whoami, cmd_health, cmd_check_key, cmd_ping subcommands
- Add cmd_register_user, cmd_login (OPAQUE), cmd_refresh_keypackage
- Hybrid PQ envelope (X25519 + ML-KEM-768) on all send/recv paths
- E2E test suite expanded
Other:
- quicnprotochat-gui: Tauri 2 desktop GUI skeleton (backend + HTML UI)
- quicnprotochat-p2p: iroh-based P2P transport stub
- quicnprotochat-core: app_message, hybrid_crypto modules; GroupMember API updates
- .github/workflows/size-lint.yml: binary size regression check
- docs: protocol comparison, roadmap updates, fully-operational checklist

fix: address 16 architecture design flaws across all crates
...
Phase 1 — Foundation:
- Constant-time token comparison via subtle::ConstantTimeEq (Fix 11)
- Structured error codes E001–E020 in new error_codes.rs (Fix 15)
- Remove dead envelope.capnp code and related types (Fix 16)
Phase 2 — Auth Hardening:
- Registration collision check via has_user_record() (Fix 5)
- Auth required on uploadHybridKey/fetchHybridKey RPCs (Fix 1)
- Identity-token binding at registration and login (Fix 2)
- Session token expiry with 24h TTL and background reaper (Fix 3)
- Bounded pending logins with 5-minute timeout (Fix 4)
Phase 3 — Resource Limits:
- Rate limiting: 100 enqueues/60s per token (Fix 6)
- Queue depth cap at 1000 + 7-day message TTL/GC (Fix 7)
- Partial queue drain via limit param on fetch/fetchWait (Fix 8)
Phase 4 — Crypto Fixes:
- OPAQUE KSF switched from Identity to Argon2id (Fix 10)
- Random AEAD nonce in hybrid KEM instead of HKDF-derived (Fix 12)
- Zeroize secret fields in HybridKeypairBytes (Fix 13)
- Encrypted client state files via QPCE format (Fix 9)
Phase 5 — Protocol:
- Commit fan-out to all existing members on invite (Fix 14)
- Add member_identities() to GroupMember
Breaking: existing OPAQUE registrations invalidated (Argon2 KSF).
Schema: added auth to hybrid key ops, identityKey to OPAQUE finish
RPCs, limit to fetch/fetchWait.

WIP: add OPAQUE password-authenticated key exchange
...
Add opaque-ke (v4, ristretto255) for password-based registration and
login. Extend NodeService schema with opaqueRegisterStart/Finish and
opaqueLoginStart/Finish RPCs. Add Store trait methods for OPAQUE server
setup and user records. Initial e2e integration test scaffolding.
Note: FileBackedStore does not yet implement the new Store trait
methods — server compilation is temporarily broken.

Delete 8 Noise-specific documentation pages (noise-xx.md,
transport-keys.md, adr-001/003/006, framing-codec.md) and update
~30 remaining wiki pages to reflect QUIC+TLS as the sole transport.
Remove obsolete Noise-based integration tests (auth_service.rs,
mls_group.rs). Code-side Noise removal was done in f334ed3noreply@anthropic.com >
