Complete Service Unavailability - Server Connection Failure
ID: f118e1e4-cf1
Priority: 70
Type: one-time
Status: done
Goal
Investigate and resolve connection failures on core endpoints.
Work Log
2026-04-04 — Slot 2
Issue: Linkcheck reported status 0 on all endpoints during a service restart cycle.
Root cause: Transient — the API service was in the middle of restarting (systemd deactivating/reactivating). This happens periodically when pull_main.sh resets main and systemd restarts the service.
Verification: After service restart completed, all endpoints confirmed working:
- / → 302 (redirect to /vision)
- /exchange → 200
- /gaps → 200
- /graph → 200
- /analyses/ → 200
- /atlas.html → 200
- /how.html → 301
- /pitch.html → 200
Action: No code changes needed. Issue was transient service restart.
2026-04-17 — minimax:60 (verification after audit reopen)
Verification: Confirmed server healthy after stale process cleanup:
- API status: 200
- /exchange → 200
- /gaps → 200
- /graph → 200
- /analyses/ → 200
- /atlas.html → 200
- /how.html → 301
- /pitch.html → 200
Root cause confirmed: Stale uvicorn process (PID 882720) was running but not listening on port 8000. Killed zombie process, systemd auto-restarted service via
Restart=always. No code changes needed - infrastructure/operations issue.
