+### Report provenance
+
+Every report a contract produces must lead with the **absolute path the probe
+executed from** — `pwd -P`, or the running script's absolute path. A live-state
+report without provenance is unactionable: a report from a stale copy (a worktree
+clone, a retired cron entry, a diverged consumer) looks identical to a live
+fault, and the team burns rounds repairing healthy infrastructure. This is not
+optional. The 2026-09-09 probe-drift rounds cost three false `DEGRADED` reports
+because a stale consumer probed the wrong port and nothing in the report said
+where it ran.
+
+Pair it with the **scoped any-HTTP-response liveness rule**: for unauthenticated
+or auth-gated endpoints — where any HTTP answer proves a listener is up (the
+PVE API's `401`, LiteLLM health's `301` redirect) — a probe is ALIVE on ANY HTTP
+status, including `301` redirects and `401`/`403` auth challenges. **DOWN =
+connection refused (`000`) or timeout only.**
+
+Probes whose success condition is specifically a bare `200` are NOT covered by
+the any-HTTP rule. On those — authenticated probes such as the Zulip message
+POST and the router `/health` — an unexpected status (`401`/`403` from a bad or
+missing credential, `5xx`, or anything other than the expected `200`) is an
+**ALERT**, not "alive".
+
+```markdown
+**Report format**: Begin every report with the absolute execution path
+(`pwd -P` / script path). On auth-gated endpoints, alive = ANY HTTP status and
+DOWN = `000`/timeout only; on probes whose expected result is `200`, any other
+status is an alert.
+```
+
+The lint pipeline enforces the provenance clause: any contract with a
+`**Report format**` line must state an absolute path (`pwd -P`, `absolute path`,
+or `executed from`).

+|---|---|
+| `ct-unreachable:koby:192.168.68.15` | CT 111 (tdunna/koby) runs on **storepve (.6)**, not amdpve (.15). |
+| `wrapper-*:abiba` | Abiba is pi-only since the harness purge. `/root/.local/bin/hermes` is a dangling symlink; no `hermes-real`, no `~/.hermes/.env`. |
+| `wrapper-*:koby` | Koby is **report-only** (captain ruling 2026-08-17, Rule 17): detect and report, never repair — its legs must not count as fleet failures. Koby's wrapper is also the genuine no-infisical case: it sources `~/.hermes/.env` rather than `/usr/bin/infisical`, which the check now accepts. |
+| `wrapper-infisical-path:koonimo` | Koonimo's wrapper **does** reference `/usr/bin/infisical` — but past the old check's `head -20` window, so the check looked for the path in the wrong slice and false-failed. The fix that mattered was reading the full wrapper body (and then verifying any absolute infisical path it finds actually exists). |

+## Leg 2 — infrastructure-monitoring PVE API (item 2)
+
+**Before** — the contract's probe, aimed at the monitoring host CT 116:
+
+```
+$ curl -s -o /dev/null -w '%{http_code}' https://192.168.68.116:8006/api2/json
+000
+```
+
+CT 116 runs no `pveproxy`, so it never answers on `:8006`. The probe target was
+wrong, which is what read as PVE-API `000`.
+
+**After** — probing the five real cluster nodes (`:8006/api2/json/version`),
+alive under the any-HTTP-response rule (`401` = up, unauthenticated):
+
+```
+$ for node in 192.168.68.9 192.168.68.5 192.168.68.15 192.168.68.6 192.168.68.12; do
+    printf '%s:8006 -> %s\n' "$node" "$(curl -sk -o /dev/null -w '%{http_code}' --connect-timeout 5 "https://$node:8006/api2/json/version")"
+  done
+192.168.68.9:8006 -> 401
+192.168.68.5:8006 -> 401
+192.168.68.15:8006 -> 401
+192.168.68.6:8006 -> 401
+192.168.68.12:8006 -> 401
+```
+
+`401` on every node = alive by design. `DOWN` is `000`/timeout only. (The
+contract's LiteLLM probe was the same class: `/litellm/health` answers `301` →
+`/litellm/health/liveliness`, so it is now specified as any-HTTP too.)
+
+---
+
+## Leg 3 — gpu-monitor GPU probes (item 3)
+
+**Before** — the false alarm came from probing bare port 80 on GPU hosts:
+
+```
+$ curl -s -o /dev/null -w '%{http_code}' http://192.168.68.8/health
+000
+$ curl -s -o /dev/null -w '%{http_code}' http://192.168.68.110/health
+000
+```
+
+Nothing listens on GPU port 80, so the monitor reported
+`DEGRADED — GPU-rtx3090 000, GPU-rtx5070 000` three times on 2026-09-09.
+
+**After** — the real endpoints answer:
+
+```
+$ curl -s -o /dev/null -w '%{http_code}' http://192.168.68.8:8080/health
+200
+$ curl -s -o /dev/null -w '%{http_code}' http://192.168.68.110:8080/health
+200
+$ curl -s -o /dev/null -w '%{http_code}' http://192.168.68.15:8080/health
+200
+$ curl -s -o /dev/null -w '%{http_code}' http://192.168.68.116/health/unified
+301        # Location: http://192.168.68.116/gpu/gpu-data — the same payload
+$ curl -s -o /dev/null -w '%{http_code}' -L http://192.168.68.116/health/unified
+200
+```
+
+`301` is healthy under the any-HTTP-response rule. The contract now requires GPU
+health on `:8080` (or router `/health/unified`) and forbids bare port 80 on a
+GPU host.
+
+---
+
+## Leg 4 — report provenance (item 4)
+
+Every contract report must now lead with the absolute path it executed from.
+`docs/AUTHORING-GUIDE.md` documents the rule and `scripts/prose-lint.sh`
+enforces it:
+
+```
+$ pwd -P
+/root/.treehouse/prose-contracts-9ce5f3/3/prose-contracts
+$ bash scripts/prose-lint.sh
+  ✅ Report provenance present in all report-format contracts

+✅ LINT PASSED (12 warning(s))
+```
+
+The health script prints `📍 executed from: script=… cwd=…` and includes
+`execution_path`/`cwd` in `--json` output.

+
+## Follow-up findings (observed, intentionally NOT changed here)
+
+These are adjacent stale expectations discovered while verifying the four
+scoped legs. Each touches a CRITICAL/HIGH-sensitivity artifact or an unrelated
+script, so it is recorded for the captain/verify mate rather than silently
+repaired.
+
+1. **`infrastructure-control.prose.md` (CRITICAL) CT 111 node assignment.**
+   Lines ~109 and ~615 place `tdunna` (CT 111, koby) on **amdpve**. Live
+   verification on 2026-09-10 shows `pct status 111` = `running` on
+   **storepve (.6)** and `Configuration file 'nodes/amdpve/lxc/111.conf' does
+   not exist` on .15. `agent-health-check.py` now carries the live-verified
+   `storepve` mapping (the script is not the topology source of truth); the
+   CRITICAL contract itself needs an authorized correction.
+2. **Strix Halo `:8080` firewall claim is stale.** `prose-ai-review.sh`
+   ground-truth rule #4 and `gpu-monitor.prose.md` say `:8080` is firewalled to
+   `.116` only and `.24` cannot probe it. Live on .15:
+   `-A INPUT -s 192.168.68.24/32 -p tcp --dport 8080 -j ACCEPT`, and a probe
+   from .24 returns `200`. The contract keeps routing Strix via the router
+   (safe), but the claim no longer matches iptables.
+3. **`contract-registry.yaml` references `agent-health-check.prose.md`**, which
+   does not exist in the repo. The registry entry (with `koby_action: skip_heal`)
+   is aspirational/stale.
+4. **Pre-existing script defects, untouched:** `scripts/pm2-self-heal.sh` has a
+   bash syntax error at lines 19–20 (`bash -n` fails), and `shellcheck` fails on
+   five untouched scripts (`netbird-add-domain.sh`, `pct-run.sh`,
+   `pm2-self-heal.sh`, `prose-ai-review.sh`, `swap-gpu-dense-model.sh`).
+   `scripts/prose-lint.sh` — the one shell file touched here — is now
+   shellcheck-clean.

 ## Alert Thresholds

+### Liveness rule (scoped)
+
+The any-HTTP-response rule applies ONLY to redirect/auth-gated liveness
+endpoints, where any HTTP answer proves a listener is up. Applied here: the
+router's `/health/unified` answers `301 Moved Permanently` → `/gpu/gpu-data`
+(the same payload) and LiteLLM's `/litellm/health` answers `301` →
+`/litellm/health/liveliness`. For those endpoints a probe is **ALIVE** on
+**ANY** HTTP status — `3xx` redirects and `401`/`403` auth challenges included —
+and **DOWN = connection refused (`000`) or timeout only**. Same scoped rule as
+zulip-health (Tanko) and infrastructure-monitoring.
+
+Probes whose success condition is specifically a bare `200` are NOT covered by
+the any-HTTP rule. On those — the GPU `:8080/health` endpoints, the router
+`/health`, and the dashboard — an unexpected status (`401`/`403`, `5xx`, or
+anything other than the expected `200`) is an **ALERT**, not "alive".

 ## Execution
+
+### Liveness rule (scoped)
+
+The any-HTTP-response rule applies ONLY to unauthenticated/auth-gated endpoints,
+where any HTTP answer proves a listener is up: the PVE API
+(`https://<node>:8006/api2/json/version`) and LiteLLM health
+(`/litellm/health`, `301` → `/litellm/health/liveliness`). For those endpoints a
+probe is **ALIVE** on **ANY** HTTP status — `401`/`403` auth challenges and `3xx`
+redirects included — and **DOWN = connection refused (`000`) or timeout only**.
+The PVE API legitimately answers `401` to an unauthenticated probe — that is the
+healthy signal, not a failure. Same scoped rule as zulip-health (Tanko) and
+gpu-monitor.
+
+Probes whose success condition is specifically a bare `200` are NOT covered by
+the any-HTTP rule. On those — the authenticated Zulip POST and the router
+`/health` — an unexpected status (`401`/`403` from a bad or missing credential,
+`5xx`, or anything other than the expected `200`) is an **ALERT**, not "alive".

+WHY THIS FILE EXISTS: the monitoring contracts kept emitting false alarms from
+stale expectations rather than live faults.
+
+  * agent-health-check v3 reported 6 failures that were all stale expectations:
+    abiba (pi-only since the harness purge) was tested as a Hermes host, koby
+    (report-only per the captain's 2026-08-17 ruling) was counted as repairable,
+    koby's CT 111 was probed on amdpve where it does not exist (it runs on
+    storepve .6), and the wrapper infisical check had two bugs — it read only
+    the first 20 lines, so koonimo's wrapper (which references /usr/bin/infisical
+    past line 20) false-failed, and it treated koby's genuine no-infisical
+    (~/.hermes/.env) wrapper as broken.
+  * gpu-monitor emitted "DEGRADED — GPU-rtx3090 000, GPU-rtx5070 000" three
+    times from probing bare port 80 on GPU hosts while :8080 answered 200.
+  * infrastructure-monitoring probed CT 116 for the PVE API (no pveproxy ->
+    000) instead of the five real cluster nodes, which answer 401 = alive.
+
+These tests execute the health script (with SSH/vault stubbed) and the real
+provenance consumer (scripts/prose-lint.sh), and parse the contracts' executable
+check-health probe blocks into normalized probe sets. No live network, vault, or
+SSH access is required.
