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.

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 9 — mesh identity, store-and-forward, broadcast channels
...
Self-sovereign mesh networking for offline-capable Freifunk deployments.
- MeshIdentity: Ed25519 keypair-based identity without AS registration,
JSON-persisted seed + known peers directory, sign/verify
- MeshEnvelope: signed store-and-forward envelope with TTL, hop_count,
max_hops, SHA-256 dedup ID, Ed25519 signature verification
- MeshStore: in-memory message queue with dedup, per-recipient capacity
limits, TTL-based garbage collection
- BroadcastChannel: symmetric ChaCha20-Poly1305 encrypted topic-based
pub/sub for mesh announcements, no MLS overhead
- BroadcastManager: subscribe/unsubscribe/create channels by topic
- P2pNode integration: send_mesh(), receive_mesh(), forward_stored(),
subscribe(), create_broadcast(), broadcast()
- Extended mesh REPL: /mesh send, /mesh broadcast, /mesh subscribe,
/mesh route, /mesh identity, /mesh store (feature-gated)
28 P2P tests pass (21 existing + 7 broadcast). All builds clean.

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

identity is always derived from authenticated session
- Username enumeration mitigation (Phase 4.5): 5ms timing floor on
resolveUser responses + rate limiting to prevent bulk enumeration
- Add /update-key REPL command for MLS leaf key rotation via
propose_self_update + auto-commit + fan-out to group members
- Add 4 new E2E tests: message delivery round-trip, key rotation

fix: auto-derive state file path from --username
...
qpq --username alice now automatically uses qpq-alice.bin instead of the
shared qpq-state.bin default, preventing identity collisions in multi-user
local test setups without requiring an explicit --state flag.

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

feat: auto-start local server from REPL
...
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: make repl the default subcommand
...
Running `qpq --username alice --password secretA` now launches the
REPL directly instead of requiring `qpq repl ...`. The explicit
`repl` subcommand still works for backwards compatibility.
