Description

Reproduce and fix live chat creation/resume failing after daemon restart. wg chat create hangs while the service runs; creating .chat-4 while stopped succeeds, but service start logs Coordinator-4 register_coordinator_session failed: No such file or directory, and wg chat resume .chat-4 hangs. Preserve Pi model routing and existing chat records. Add regression coverage for create while stopped, service start, and live registered chat, plus bounded IPC failure behavior.\n\n## Validation\n- cargo fmt --check\n- cargo clippy\n- focused tests for chat create/resume and coordinator session registration\n- smoke create Pi chat with openai-codex:gpt-5.6-sol while stopped, start service, verify attachable without missing-directory errors

Live repro details from coordinator check: with service restarted using --no-chat-agent, dispatcher works and agent-134 is running, but 'timeout 8 wg chat list' still times out. Current model routing resolves all roles to pi:* as expected, so the main live failure appears to be chat/session control state, not profile selection. Stale current-repo chat processes still exist from Tue Jul 7: wg tui pid 3098147, wg tui pid 3617175, codex-handler --chat chat-0 pid 3466035, codex-handler --chat chat-1 pid 3466038. Earlier service logs refused .chat-1 because chat-1 lock was held by pid 3466038 and deferred .chat-0 because TUI sentinel pid 3098147 was alive. sessions.json contains chat-0..chat-5; chat-4/chat-5 were created today. Please account for wg chat list bounded failure and stale live-lock/sentinel cleanup semantics in the fix/tests.

2026-07-12T08:25:22.031072929+00:00 Task reset for retry from in-progress (attempt #1) — killed agent agent-132 (PID 770494) — reason: agent-132 became defunct mid-validation; retrying in place to preserve chat coordinator WIP diff and finish validation
2026-07-12T08:26:38.724825248+00:00 Spawned by coordinator --executor pi --model openai-codex:gpt-5.6-sol
2026-07-12T08:26:46.955607739+00:00 Starting implementation; inspecting prior WIP and chat coordinator registration paths.
2026-07-12T08:32:38.633027515+00:00 Task marked as failed: Agent exited with code 1
2026-07-25T09:16:26.495254927+00:00 Reset by `wg recover` — reason: mass failure on gpt-5.6-sol/minimax; shifting all to zai glm-5.2 per current profile
2026-07-25T19:09:25.042907445+00:00 Spawn failed (attempt 1/5): build-heavy admission budget full (1/1). exec_mode=default, executor=pi
2026-07-25T19:09:30.029173393+00:00 Spawn failed (attempt 2/5): build-heavy admission budget full (1/1). exec_mode=default, executor=pi

2026-07-25T19:28:59.532117315+00:00 Starting fresh (agent-789). Inspecting chat coordinator registration paths: register_coordinator_session, chat create/resume, sessions.json
2026-07-25T19:59:30.570545990+00:00 Root cause reproduced & fixed: sessions.json save() shared one sessions.json.tmp; concurrent uncoordinated writers (TUI create + daemon coordinator fan-out on restart) collided -> rename ENOENT -> 'register_coordinator_session failed: No such file or directory' -> chat dir never created -> create/resume hung. Fix: per-call unique tmp (.sessions.json.tmp.<pid>.<tid>.<nonce>) in save(). Added 3 regression tests + smoke chat_create_while_stopped_starts_clean.sh. fmt/clippy/tests all green.
