Per defect report 1150.msg:
- GPU exporters: probe /metrics (Prometheus scrape target), not bare /
- Grafana: correct port 3001 (not 3000)
- All probes: print target name + full URL + HTTP code
- All probes: retry once at 25s on 000/timeout
- Apply standing rules: any HTTP status = ALIVE; only 000/timeout/refused = probe-failed
Verified: all probes now return real HTTP codes (GPU 200, Grafana 200, Router 200, LiteLLM 301)
- infrastructure-monitoring: Correct Zulip key path to /etc/litellm-monitor.env
(not /etc/zulip-bot.env which doesn't exist); add credential-missing check;
remove unused monitor_key variable
- litellm-health: Clarify that syslog-auto is a fallback pool alias, not a
step 7 probe; monitor key must be scoped for all four aliases
- litellm-health.prose.md: Make monitor key retrieval explicit (ssh from CT 100 to CT 116)
with executable commands; add syslog-auto alias; document credential-missing failure
condition (not bare 401 or 0 keys)
- infrastructure-monitoring.prose.md: Fix Zulip POST probe to retrieve keys from CT 116
via ssh instead of sourcing local env file that doesn't exist on executor host
- Verify model inference probes return 200 for gpu-dense, gpu-vision, strix-moe,
syslog-auto with corrected credential retrieval
Second probe-drift correction pass after #65/#66/#68. All four legs were stale
consumer expectations, not live faults.
1. scripts/agent-health-check.py (v4)
- abiba declared pi-only runtime (harness purge): Hermes-era gateway, config
and wrapper legs are skipped instead of failing.
- koby declared report_only (captain ruling 2026-08-17, Rule 17): every koby
leg is detected and reported, never counted as a fleet failure or repaired.
- koby's CT 111 mapping corrected to storepve (.6); the old amdpve mapping
made `pct status 111` fail and read as ct-unreachable.
- wrapper check no longer FAILs .env-based wrappers that legitimately never
invoke infisical (koonimo).
- keys load in main() (load_agent_keys) so the module is importable/testable.
- every run prints absolute execution provenance (script + cwd), in the header
and in --json.
Before: 6 FAILURE(S). After: 0 failures, koby reported read-only.
2. infrastructure-monitoring.prose.md
- PVE API probe repointed from CT 116 (no pveproxy, 000) to the five real
nodes on https://<node>:8006/api2/json/version, all 401 = alive.
- any-HTTP-response liveness rule added (401/3xx alive; 000/timeout = DOWN).
- LiteLLM health documented as 301 -> /litellm/health/liveliness, not bare 200.
3. gpu-monitor.prose.md
- GPU health probes on :8080 (or router /health/unified); bare port 80 on a
GPU host is forbidden (no listener -> false DEGRADED).
- router /health/unified 301 -> /gpu/gpu-data documented as alive.
- port-discipline + liveness rule + direct-fallback execution step.
4. Report provenance (all contracts)
- docs/AUTHORING-GUIDE.md documents the rule; scripts/prose-lint.sh enforces
that any **Report format** contract states an absolute path (pwd -P).
- provenance added to gpu-monitor, infrastructure-monitoring, proxmox-monitor.
Tests: tests/test_probe_drift.py (23 passed); prose-lint.sh clean + shellcheck
clean; CI frontmatter validation passes. Evidence with per-leg before/after and
absolute paths: docs/probe-drift-round2-evidence.md.
PR #50's content was squash-merged out-of-band (2dfc3e1, 2026-08-30) while
the PR itself stayed open, double-applying the check-health/Execution
section. This drops the second copy; keeps one canonical
Execution -> check-health -> Phases 1-4 -> Verification Commands flow.
Fixes the canned 'API UNREACHABLE (HTTP 000)' reporting. Adds an explicit
check-health execution section (Zulip POST, pm2, GPU exporters, Prometheus,
Grafana, LiteLLM probes) with a hard RUN LIVE, NEVER ECHO rule, mirroring
the gpu-monitor contract pattern. Captain priority 2026-08-22.
