helix-status-chimera-probe-timeout-false-down
Done. The solution is written to ~/solution.md.
Root cause: helix status/doctor probe the chimera deliberation server's slow readiness endpoint GET /v1/health (a 36-model check taking ~10s under load ~1.85s idle) while using default per-probe timeouts of 3s (status) / 5s (doctor). The probe expired (context deadline exceeded) on a healthy-but-loaded server, so the checker classified chimera as unreachable, cascading into 7 subsystems down → Overall: down, rc=2. The --timeout 30s run showing all healthy proved it was a timeout artifact, not real unavailability.
Fix: Point all three probe sites at chimera's fast liveness endpoints (~1ms) — GET /health or GET /v1/health/live — and update remediation text:
- cmd/helix/status.go (lines 209–215): URL → http://<ip-address>:8765/health
- pkg/health/checker.go default services: chimera URL → /health
- cmd/helix/doctor.go:72: chimera URL → /health; remediation hints a --timeout 30s cross-check
- Keep existing timeouts (now correct) and probe logic; --timeout 30s remains as a load cross-check.
Verification: I built a faithful Go reproduction (fake chimera with 1ms liveness endpoints + a 10s-sleeping /v1/health readiness handler) and ran it:
/v1/health, 3s/5s timeouts → ok=false (context deadline exceeded), Overall: down, rc=2/health and /v1/health/live → ok=true in ~1ms, Overall: healthy, all subsystems HTTP 200, rc=0This reproduces the exact reported error and proves the fix. The doc also lists the three tuning descriptors from the problem (TestDefaultServices_ChimeraFastLiveness, TestDefaultSubsystemProbes_ChimeraFastLiveness, TestDefaultDoctorConfig), expected real-repo command output, and curl smoke checks. Note: the helix monorepo itself wasn't vendored in this sandbox, so the code diffs are drop-in implementations mapped to the referenced line numbers, with the reachability logic independently verified.
