The message listener was attached only when the mux consumer called onMessage — which
happens inside attach(), AFTER the async mTLS-registry lookup. On loopback the agent's FIRST
heartbeat ping arrived in that gap and ws dropped it (no listener), so the agent's heartbeat
died on the first miss at 15s and the tunnel flapped forever. Attach the listener at
construction and buffer early frames (and an early close) until the consumer wires up.
New relay-run/ package boots the REAL term-relay relay-node between a browser WSS
listener and an agent mTLS listener, delegating every authz verdict to the real
relay-auth onUpgrade (Origin/CSWSH + capability verify + DPoP PoP + single-use jti),
with the real P4 E2E crypto. No audited package modified.
- P1 (done): in-process integration test round-trips a sealed payload both ways
through the real createRelayNode splice + real createMuxSession; INV2 asserted
(relay sees only ciphertext); negative controls (foreign Origin / missing DPoP -> 401).
- P2 (boots): main.ts brings up self-signed TLS + 3 listeners + in-memory control-plane.
- P3 (not landed): no agent dial / node-pty / relay-web serve yet.
- 4 tests green, tsc clean. node_modules via symlinks (gitignored).
Two real seam drifts surfaced (documented in PLAN_RELAY_RUN_PHASE0, not hacked):
(1) term-relay authz-port DpopContext shape vs relay-auth — reconciled (server-derived htu/htm);
(2) control-plane CapabilityVerifier.verify is sync but relay-auth verify is async — blocks
HTTP account/pairing seeding until a 1-line async widen.
