test: add comprehensive NIP-AC WebRTC call state machine tests
Add 81 tests across two test suites covering the full NIP-AC spec: - quartz/NipACStateMachineTest (31 tests): Protocol compliance test vectors for event structure, tags, P2P/group flows, ICE serialization, staleness, renegotiation glare rules, and multi-device support - commons/CallManagerTest (50 tests): State machine integration tests using real NostrSignerInternal with actual crypto, covering: * Full call lifecycle (Idle → Offering/IncomingCall → Connecting → Connected → Ended → Idle) * Call rejection, busy auto-reject, hangup from any state * Self-event filtering (ICE, hangup, answer-elsewhere) * Mid-call renegotiation (voice ↔ video) * Group calls (mesh discovery, partial disconnect, invite peer) * Interface-level tests with real signing + gift wrapping pipeline * Full end-to-end P2P flow with two CallManager instances Also adds test vector tables to NIP-AC.md spec for other implementers. https://claude.ai/code/session_01AfRYTRCvtKqqDxeKQujUrx

- Clients SHOULD handle `ICE_CONNECTION_FAILED` state by ending the call and notifying the user of a connection failure.

## Test Vectors
|
||||
|
||||
Implementations SHOULD validate their state machine and event handling against these test scenarios.

### Event Structure Tests
|
||||
|
||||
| # | Test | Verification |
|
||||
|---|------|-------------|
|
||||
| E1 | Build Call Offer (kind 25050) | Contains `p`, `call-id`, `call-type`, `alt` tags; content = SDP offer |
|
||||
| E2 | Build Call Answer (kind 25051) | Contains `p`, `call-id`, `alt` tags; content = SDP answer; NO `call-type` tag |
|
||||
| E3 | Build ICE Candidate (kind 25052) | Contains `p`, `call-id`, `alt` tags; content = JSON with `candidate`, `sdpMid`, `sdpMLineIndex` |
|
||||
| E4 | Build Call Hangup (kind 25053) | Contains `p`, `call-id`, `alt` tags; content MAY be empty or contain reason |
|
||||
| E5 | Build Call Reject (kind 25054) | Contains `p`, `call-id`, `alt` tags; content MAY be `"busy"` for auto-reject |
|
||||
| E6 | Build Call Renegotiate (kind 25055) | Contains `p`, `call-id`, `alt` tags; content = new SDP offer |
|
||||
| E7 | Group offer with N callees | N `p` tags present, one per callee |
|
||||
| E8 | ICE candidate in group call | Still addressed to single peer (1 `p` tag) |
|
||||
| E9 | All events for same call share `call-id` | Offer, answer, ICE, hangup, reject, renegotiate — same UUID |
|
||||
|
||||
### State Machine Tests
|
||||
|
||||
| # | Scenario | Initial State | Event/Action | Expected State |
|
||||
|---|----------|---------------|-------------|----------------|
|
||||
| S1 | Receive offer from followed user | Idle | CallOffer | IncomingCall |
|
||||
| S2 | Receive offer from non-followed user | Idle | CallOffer | Idle (ignored) |
|
||||
| S3 | Accept incoming call | IncomingCall | acceptCall() | Connecting |
|
||||
| S4 | ICE peer connected | Connecting | onPeerConnected() | Connected |
|
||||
| S5 | Peer hangs up (P2P) | Connected | CallHangup | Ended(PEER_HANGUP) |
|
||||
| S6 | Ended auto-resets | Ended | ~2s timeout | Idle |
|
||||
| S7 | Initiate outbound call | Idle | initiateCall() | Offering |
|
||||
| S8 | Receive answer to offer | Offering | CallAnswer | Connecting |
|
||||
| S9 | Reject incoming call | IncomingCall | rejectCall() | Ended(REJECTED) |
|
||||
| S10 | Peer rejects our offer (P2P) | Offering | CallReject | Ended(PEER_REJECTED) |
|
||||
| S11 | Busy auto-reject | Connected | CallOffer (different call-id) | Connected + publish CallReject("busy") |
|
||||
| S12 | Stale event (>20s old) | Any | Any signaling event | No state change |
|
||||
| S13 | Duplicate event (same ID) | Any | Re-delivered event | No state change |
|
||||
| S14 | Self ICE candidate echo | Any active | CallIceCandidate from self | Ignored |
|
||||
| S15 | Self hangup echo | Connected | CallHangup from self | Ignored (stay Connected) |
|
||||
| S16 | Self answer in IncomingCall | IncomingCall | CallAnswer from self | Ended(ANSWERED_ELSEWHERE) |
|
||||
| S17 | Self answer in Offering | Offering | CallAnswer from self | Ignored (stay Offering) |
|
||||
| S18 | Hangup from Offering | Offering | hangup() | Ended(HANGUP) |
|
||||
| S19 | Hangup from Connecting | Connecting | hangup() | Ended(HANGUP) |
|
||||
| S20 | Hangup from Connected | Connected | hangup() | Ended(HANGUP) |
|
||||
| S21 | Hangup from Idle | Idle | hangup() | Idle (no-op) |
|
||||
|
||||
### Renegotiation Tests
|
||||
|
||||
| # | Scenario | Verification |
|
||||
|---|----------|-------------|
|
||||
| R1 | Renegotiate in Connected state | Forwarded to callback |
|
||||
| R2 | Renegotiate in Connecting state | Forwarded to callback |
|
||||
| R3 | Renegotiate in Idle state | Ignored |
|
||||
| R4 | Renegotiate with wrong call-id | Ignored |
|
||||
| R5 | Renegotiation response | MUST be CallAnswer (kind 25051), NOT CallRenegotiate |
|
||||
| R6 | Glare tiebreaker | Higher pubkey wins; lower pubkey rolls back |
|
||||
|
||||
### Group Call Tests
|
||||
|
||||
| # | Scenario | Verification |
|
||||
|---|----------|-------------|
|
||||
| G1 | Group offer detected | Multiple `p` tags → group call |
|
||||
| G2 | Peer rejects in group | Removed from group; call continues with remaining |
|
||||
| G3 | All peers reject | Call ends |
|
||||
| G4 | Partial disconnect | Close only that peer's connection; continue with remaining |
|
||||
| G5 | Last peer leaves | Call ends |
|
||||
| G6 | Discover peer while ringing | Buffer peer; trigger mesh setup after accepting |
|
||||
| G7 | Mid-call offer (callee-to-callee) | Forwarded via onMidCallOfferReceived callback |
|
||||
| G8 | Invite new peer | Offer with all existing members + new invitee in `p` tags |
|
||||
| G9 | Callee-to-callee glare | Lower pubkey initiates; higher waits |
|
||||
|
||||
### Interface-Level Tests (Full Pipeline)
|
||||
|
||||
| # | Scenario | Verification |
|
||||
|---|----------|-------------|
|
||||
| I1 | Initiate call | Publishes 1 EphemeralGiftWrap (kind 21059) |
|
||||
| I2 | Accept call | Publishes EphemeralGiftWrap answer(s) |
|
||||
| I3 | Reject call | Publishes EphemeralGiftWrap reject(s) |
|
||||
| I4 | Hangup | Publishes EphemeralGiftWrap hangup(s) |
|
||||
| I5 | Send renegotiation | Publishes 1 EphemeralGiftWrap renegotiate |
|
||||
| I6 | Busy auto-reject | Publishes EphemeralGiftWrap reject while staying in current call |
|
||||
| I7 | Group per-peer offers | Publishes 1 EphemeralGiftWrap per peer |
|
||||
| I8 | Invite peer | Publishes 1 EphemeralGiftWrap; invitee added to pending set |
|
||||
| I9 | Full P2P flow | Offer → Answer → Renegotiate → Hangup, all via gift wraps |
