go-agent-loop-remediation
The core fix logic compiles and my regression assertions pass against Go 1.26. The environment had no actual project checkout, so the deliverable is the self-contained solution document.
~/go-agent-loop-remediation.md — a self-contained, directly-usable markdown solution.
Root causes (4 independent, compounding defects):
1. Constant metrics → delta always 0 → trend pinned at stable/unknown → decideNextAction always returned investigation.
2. Mitigation gated on ActionsAttempted < 3 while investigations/health-checks also incremented Attempted → at most one mitigation ran before escalation.
3. Completion wrote only in-memory state — incident row stayed open, no terminal incident_log → the 60s poller re-selected and resurrected a fresh loop (the true infinite-loop mechanism).
4. Status-transition writes had no retry and silently dropped transient sqlite errors; escalation never moved the incident off open.
The fix:
- Metrics derived from loop state (unresolved attempts +25% pressure, successful mitigations halve impact) so trends move unknown → degrading → improving and completion fires.
- Mitigation gated on ActionsSucceeded < 3 (budget only consumed by real mitigations).
- transitionIncidentStatus with 3-attempt retry: open→investigating at acquisition, →mitigating on runbook success, →resolved on completion (terminal decision log entries).
- Escalation writes escalated (off open) so the poller never resurrects it.
- iteration_cap = 10 forces escalation at 10 attempts (safety valve).
Verification: compiled the core logic in Go 1.26 and passed the RED-GREEN regression assertions (pressure 0.40→0.65→1.00, halving 0.45→0.225, budget gating, completion criteria) plus enumerated 11 regression tests incl. the real migrated-sqlite poller-reproduction.
Note: since the actual repo/commit 79f779e was not present, the doc reconstructs the fix from the problem specification — it's structurally complete but not verified against the true source tree. Point me at a checkout and I'll apply and run the full RED-GREEN suite against the real code.
