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

Remove Noise protocol references from wiki docs and tests
...
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 >

feat: add post-quantum hybrid KEM + SQLCipher persistence
...
Feature 1 — Post-Quantum Hybrid KEM (X25519 + ML-KEM-768):
- Create hybrid_kem.rs with keygen, encrypt, decrypt + 11 unit tests
- Wire format: version(1) | x25519_eph_pk(32) | mlkem_ct(1088) | nonce(12) | ct
- Add uploadHybridKey/fetchHybridKey RPCs to node.capnp schema
- Server: hybrid key storage in FileBackedStore + RPC handlers
- Client: hybrid keypair in StoredState, auto-wrap/unwrap in send/recv/invite/join
- demo-group runs full hybrid PQ envelope round-trip
Feature 2 — SQLCipher Persistence:
- Extract Store trait from FileBackedStore API
- Create SqlStore (rusqlite + bundled-sqlcipher) with encrypted-at-rest SQLite
- Schema: key_packages, deliveries, hybrid_keys tables with indexes
- Server CLI: --store-backend=sql, --db-path, --db-key flags
- 5 unit tests for SqlStore (FIFO, round-trip, upsert, channel isolation)
Also includes: client lib.rs refactor, auth config, TOML config file support,
mdBook documentation, and various cleanups by user.
