fix(alignment): correct tanko status - hybrid (DSH + Hermes), not DSH-only

PR #145 originally claimed 'the other 3 CTs are DSH-only' but all 4 agents run a Hermes gateway. Only tanko additionally runs DSH, making it the hybrid one. Fixed line 300 to say what the contract actually checks for each agent, and fixed line 76 to stop asserting tanko's Hermes config is gone.
fix(alignment): clarify tanko's live LiteLLM proxy status in health-check description

+# Agent Health Check
+
+Consolidated health verification for the LiteLLM + GPU + Zulip + gateway fleet.
+Runs every 4 hours (2, 6, 10, 14, 18, 22 UTC at :35) via cron (`35 2,6,10,14,18,22 * * *`) and on-demand. Never restarts anything — detects and reports only.
+
+**Cadence rationale** (2026-08-28 decision): monitoring dispatches moved from hourly to every 4 hours to reduce probe load on GPU hosts while keeping detection latency acceptable (up to 4 hours).
+
+## Requires
+
+- **LiteLLM admin key** for key validation (retrieved from `/root/.pi/agent/env.sh`)
+- **SSH access** to GPU hosts — `llmuser` on .8 (owns `llama-server`), `root` on .110 and .15 — and agent CTs (.122, .129, .114, .24)
+- **Python 3** for script execution
+- **Network access** to LiteLLM (:4000), GPU exporters (:9400), and gateway endpoints
+
+## Maintains
+
+- last_check: timestamp — When the last full diagnostic ran
+- overall_severity: "healthy" | "degraded" | "critical"
+- liteLLM_keys: map of agent → key validity
+- gpu_ports: map of host → port conflict status
+- agents: map of agent → streaming health + gateway liveness
+- ct_liveness: map of CT → active status
+- config_integrity: map of config file → valid/invalid
+
+## Execution
+**Execution model**: This contract is executed by a host-scheduled cron job (see
+`scripts/contract-run.sh`). The cron job runs the monitoring script directly on the
+target host and appends the result to `/var/log/contract-runs/<contract>.log`. An
+agent-session acknowledgement (a `done:` line in the ops status log) is NOT
+execution — it only proves the agent read the result and reported it. The actual
+monitoring work happens in the host cron job.
+
+
+### check-health
+
+**RUN LIVE, NEVER ECHO — every dispatch must execute the script with real tool
+calls; never repeat a prior report unless a live probe fails.**
+
+```bash
+# Run the consolidated health check script
+python3 /root/scripts/agent-health-check.py --json
+```
+
+**Report format**: Begin every report with the **absolute path the script
+executed from** so a stale-consumer report is distinguishable from a real fault
+at read time. Summarize actual results from each check. Apply the standing probe
+rules: any HTTP status = ALIVE; only 000/timeout/refused = probe-failed.
+
+**Expected output**: JSON with `overall_severity` field. If `healthy`, report
+"Agent health check: OK". If `degraded` or `critical`, report the specific
+failures and their severity.
+
+**Mandatory report legs** (2026-09-17 decision, 1295.msg): Every report line
+MUST include one clause per check leg, in every state: healthy, degraded/warn,
+skipped, or failed. A missing leg must never look the same as a healthy leg.
+Required legs and their templates in every state:
+
+- `LiteLLM keys: 4/4 (tanko, abiba, koby, koonimo) valid`
+  - degraded: `LiteLLM keys: 2/4 (tanko valid; koby invalid; koonimo valid; abiba probe-failed: 192.168.68.116:4000 timeout)`
+  - skipped: `LiteLLM keys: SKIPPED (LiteLLM router unreachable)`
+- `GPU ports: 3/3 (rtx3090, rtx5070, strixhalo) healthy`
+  - skipped: `GPU ports: SKIPPED (no SSH access to GPU hosts)`
+  - degraded/warn: `GPU ports: 2/3 (rtx3090 healthy; rtx5070 degraded: svc=inactive, port owned by 1234; strixhalo healthy)`
+  - failed: `GPU ports: 2/3 (rtx3090 healthy; rtx5070 probe-failed: 192.168.68.110:9400 timeout; strixhalo healthy)`
+  - The GPU leg has six non-healthy states the code can produce:
+    (i) `gpu-unreachable:{host}` — SSH probe failed;
+    (ii) `gpu-no-port:{label}` — SSH worked, port not listening;
+    (iii) `gpu-ghost:{label}:{pid}` — unit inactive, port owned by another pid;
+    (iv) unit not active, MainPID empty or port owned by MainPID — svc inactive;
+    (v) unit active, /health body contains "error" — error response;
+    (vi) unit active, /health body unrecognised — unknown health.
+    In every case the failing host and reason must be named.
+- `CTs: 4/4 running (tanko, abiba, koby, koonimo)`
+  - degraded: `CTs: 3/4 (tanko running; abiba running; koby probe-failed: ssh root@192.168.68.129 timeout; koonimo running)`
+  - skipped: `CTs: SKIPPED (SSH access unavailable)`
+- `Vault secrets: 3/3 present`
+  - degraded: `Vault secrets: 2/3 (tanko present; koby present; koonimo missing)`
+  - skipped: `Vault secrets: SKIPPED (vault not configured)`
+
+The compact form in the summary line is acceptable (e.g. `rtx5070 timeout`) as
+long as the host is identifiable from context; the full `probe-failed: <target>
+<kind>` form is required when a leg reports a failure in the detail section.
+
+### Probe Shape (per standing rules from 1150.msg)
+
+1. **Any HTTP status means ALIVE.** 200, 301, 302, 401, 403, 404 all prove the
+   service answered — report the code, never "down". A redirect is not a failure.
+   Only a failed CONNECTION (curl status 000, timeout, refused) is a failed probe.
+2. **A failed probe is never a service verdict.** Print
+   `probe-failed: <target> <kind>` naming the exact URL/host/port and the failure
+   kind (timeout, refused, no-route, dns), retry once at a longer timeout, and only
+   then report.
+3. **Say which probe produced each number.** "Grafana: 000" is unusable;
+   "Grafana http://192.168.68.116:3001/api/health -> connection timeout after 10s
+   (retried at 25s: also timeout)" is actionable.
+
+## Strategies
+
+### When LiteLLM keys are invalid
+Report the specific agent + key name. Do not attempt to fix — credential
+rotation is a separate operation.
+
+### When GPU port conflicts are detected
+Report the conflicting ports and processes. Do not kill processes — that's a
+destructive action requiring captain approval.
+
+### When gateway liveness is degraded
+Report the specific CT + gateway status. Do not restart unless the restart
+debounce window has passed.
+
+### When CT liveness is down
+Report the specific CT. Do not restart — that's a destructive action.
+
+### When config YAML is invalid
+Report the specific file + parse error. Do not fix — that's a config change.
+
+### When gateway log health is degraded
+Report the specific gateway + log health status (error patterns, stale connections, connectivity issues). Do not restart — that's a destructive action.
+
+Note: the script may perform additional diagnostics beyond the seven contract checks listed under Execution.
+
+## Continuity
+

+- **On `agent-health` command**: Run on-demand and report to user

+
+## Purpose
+
+Give one daily, machine-collected picture of the estate so drift and outages
+are seen the day they happen rather than when something breaks. It is a
+*report*, not a repair: it changes nothing.
+
+## Execution pinning
+
+**Pinned execution path:**
+
+```
+/root/abiba-workspace/projects/prose-contracts/scripts/daily-infra-report.py
+```
+
+**Pinned clone:** `/root/abiba-workspace/projects/prose-contracts`
+
+That is the cron's `FM_HOME` clone and the only stable, non-ephemeral copy.
+The treehouse clone (`/root/.treehouse/agent-workspace-*/…/projects/prose-contracts`)
+is a **per-agent working copy and must NOT be pinned or executed from** — it
+drifts onto feature branches, which is exactly how a stale producer reported a
+stale picture and nobody noticed.
+
+See `docs/contract-execution-pinning.md`. Schedule and alerting live in
+`/etc/cron.d/contract-runner` on CT 100:
+
+```
+30 10 * * * FM_HOME=/root/abiba-workspace /root/abiba-workspace/bin/fm-send.sh ops "run contract: daily-health-digest" > /dev/null 2>&1
+```
+
+Invocation (credentials come from the vault; never inline them):
+
+```bash
+cd /root/abiba-workspace/projects/prose-contracts
+infisical run --env=prod -- python3 scripts/daily-infra-report.py
+```
+
+## Output shape
+
+Modes:
+
+| invocation | effect |
+| --- | --- |
+| *(none)* | collect, build the HTML dashboard, email it |
+| `--test-email` | same but with a `🧪 TEST —` subject prefix |
+| `--json` | print the collected data as JSON to stdout and **send no email** |
+
+`--json` emits a single object with these top-level keys (observed on a live
+run 2026-09-25):
+
+| key | type | meaning |
+| --- | --- | --- |
+| `nodes` | object (5) | per-node cpu/ram/disk/uptime/status |
+| `node_count`, `nodes_online` | int | Proxmox node totals |
+| `pve_probe_status`, `resources_probe_status` | `ok`\|`unreachable` | probe outcome |
+| `total_vms`, `running_vms`, `stopped_vms`, `vms_by_node` | — | guest inventory |
+| `storage`, `nfs` | array | datastore and mount usage |
+| `litellm` | object | inference checks |
+| `zulip_ext` | object | Zulip queue/serving state |
+| `agents` | object | per-agent health |
+| `docker_vm`, `docker_syslog`, `docker_netbird`, `endpoints` | object/array | Docker hosts and probed endpoints |
+
+## What a healthy run looks like
+
+```
+$ infisical run --env=prod -- python3 scripts/daily-infra-report.py --json
+  "nodes_online": 5,  "node_count": 5,  "pve_probe_status": "ok",
+  "resources_probe_status": "ok",  "running_vms": 22,  "total_vms": 22
+EXIT=0
+```
+
+and in delivery mode:
+
+```
+   report ready: 16208 chars of HTML (delivered as a file attachment)
+   Sending to the captain's Zulip DM...
+   ✅ Delivered to Zulip DM (user 9), message id 86221, attachment 16208 bytes
+      at /user_uploads/2/45/m1cQesBFV78BGeNY2lN8xkN5/infra-report-20260926-153406.html
+```
+
+Healthy means: every probe reports `ok`, `nodes_online == node_count`, and the
+email leg reports a successful send.
+
+## Exit-code semantics — as they actually behave
+
+Verified on 2026-09-25 by running each case deliberately.
+
+| condition | exit | alert | notes |
+| --- | --- | --- | --- |
+| all probes reachable, email sent | 0 | — | healthy |
+| **missing `PVE_TOKEN`** | **1** | yes | `PROBE FAILURES: proxmox: node list unreachable (PVE_TOKEN missing or API down)`, and `cluster resources unreachable` |
+| **Proxmox probe unreachable** | **1** | yes | same path as above; `pve_probe_status: unreachable` |
+| **missing/rejected Zulip credential** | **1** | yes | delivery is the only output path; report printed and persisted |
+| **upload or message post fails** | **1** | yes | report printed and persisted; message names which step failed |
+
+The distinction is deliberate and must not be flattened:
+
+* A **missing PVE token or an unreachable probe is a real failure** — the report
+  would otherwise claim zero nodes and still look successful. That was the
+ 2026-09-25 silent-zero defect (fixed in PR #133); it now exits 1.
+* A **missing email credential is survivable** — the report is still produced
+  and is still useful. It is a `DEGRADED` leg and exits 0 by design.
+
+`PROBE_FAILURES` and `DEGRADED_LEGS` are separate lists for exactly this
+reason. Do not merge them.
+
+## Delivery: Zulip DM carrying the report as an HTML ATTACHMENT
+
+Captain's decision 2026-09-26, clarified the same day: the digest is delivered to
+his **Zulip DM (user id 9)** from `abiba-bot@chat.sysloggh.net`, as an **HTML
+FILE** — an attachment, not HTML rendered in the message body and not a Markdown
+translation of it.
+
+* the styled dashboard is built exactly as before and written to
+  `/var/log/daily-infra-report/infra-report-<UTCstamp>.html`;
+* it is uploaded through `POST /api/v1/user_uploads`;
+* the **message body stays short Markdown** — subject line, top-line status
+  (nodes online, guests running, any degraded legs), and a link to the
+  attachment. The attachment IS the report; the body does not reproduce it.
+
+This removes the Google dependency entirely: **no SMTP, no `EMAIL_PASSWORD`, no
+app password, nothing to rotate.** `daily-digest-mail-transport-20260921` is
+closed under this option.
+
+The **10,000-character message cap does not apply** — it bounds message TEXT
+only, and the report travels as a file. Do not shrink the report to fit it.
+
+The credential is abiba-bot's Zulip key already on the execution host at
+`/root/.pi/agent/extensions/zulip/.env` (`ABIBA_ZULIP_API_KEY`, mode 600,
+root-readable). **Do not place a new credential in the vault** — under the
+auth-keys charter that is a captain decision.
+
+## What counts as a failure
+
+A run FAILS (exit 1) when the report cannot be trusted or delivered:
+
+* any probe is unreachable, so a section would silently be empty;
+* `PVE_TOKEN` is missing;
+* the Zulip credential is missing or rejected, or the upload/post fails.
+
+There is **no degraded delivery leg any more**. Delivery is the only output
+path, so a missing credential is a failure rather than a survivable degradation —
+the previous "missing `EMAIL_PASSWORD` still exits 0" rule is retired with the
+mail transport.
+
+**A delivery failure must never swallow the report.** On failure the script
+prints the report body to stdout *and* leaves the HTML artifact on disk, so the
+content is always recoverable from the run log. That closes the queued defect
+where a failed send printed only the transport error and the report never
+surfaced.
+
+## Failure behaviour
+
+* Non-zero exit with the alert text above; on the scheduled path the dispatch is
+  a firstmate message, so the ops lane sees it and reports it.
+* On a probe failure the report must **not** be treated as evidence about the
+  estate — a `0/0` Proxmox section means "could not look", not "nothing there".
+  That reading is why the 2026-09-25 defect went unnoticed.
+
+## Verification
+
+```bash
+# data path, no email
+cd /root/abiba-workspace/projects/prose-contracts
+infisical run --env=prod -- python3 scripts/daily-infra-report.py --json \
+  | grep -E 'pve_probe_status|node_count|nodes_online'
+
+# delivery path
+infisical run --env=prod -- python3 scripts/daily-infra-report.py --test-zulip
+```
+
+Regression tests: `tests/test_daily_infra_report.py` (7 tests). Four of them
+fail against the pre-fix script, which is what makes them bite.

+The schedule is `0 20 * * *` (20:00 LOCAL = 00:00 UTC, since host timezone is America/New_York).
+This applies **only** to the PBS datastore (`/tank/pbs-backup`), NOT to media volumes.
+Media volumes (/media/*) are report-only at all threat levels.

+The cron runs `/usr/local/bin/pbs-gc.sh` which executes:

+This is NOT a `prune` operation; it is a GC pass that reclaims unreferenced chunks.
+There is no `--keep-daily` flag; retention is governed by jobs.cfg (keep-daily=35).

+# Contract execution pinning
+
+Which copy of a contract script actually ran, and how that is proven.
+
+## Why this exists
+
+Three times on 2026-09-25 a contract reported a verdict from a copy that was
+not the merged one:
+
+1. The ops lane's own clone sat on the merged feature branch
+   `fix/search-stack-multi-engine-20260925` at `8b2eba4` with no `pve_auth`
+   fix, while it executed the daily digest from a different clone. Nothing in
+   the workflow noticed.
+2. `scripts/search-stack-check.py` was deployed into the pinned runner clone
+   by hand rather than through git.
+3. A stale local `origin/master` ref made an ancestry check report
+   "unlanded work" for a branch that had in fact merged — the same staleness
+   would have passed a stale script as current.
+
+A contract verdict is only meaningful if it came from the merged copy. The
+control is `scripts/revision-preflight.sh`.
+
+## The rule
+
+**Every contract pins exactly one clone for execution: the clone that
+`scripts/contract-run.sh` itself lives in.**
+
+`contract-run.sh` derives that from its own location (`SCRIPTS_DIR`) and checks
+the script it is about to run against `origin/master` in the same clone. There
+is no second path to configure, and no contract may be executed from a
+hand-copied location.
+
+| Contract | Script | Pinned clone |
+| --- | --- | --- |
+| `infrastructure-monitoring` | `scripts/infra-monitoring.sh` | the clone containing `contract-run.sh` |
+| `proxmox-monitor` | `scripts/proxmox-monitor.sh` | same |
+| `zulip-health` | `scripts/zulip-monitor.sh` | same |
+| `agent-health-check` | `scripts/agent-health-check.py` | same |
+| `litellm-health` | `scripts/litellm-health-check.py` | same |
+| `disk-gc-threat-response` | `scripts/disk-gc-scan.py` | same |
+| `pm2-self-heal` | `scripts/pm2-self-heal.sh` | same |
+| `search-stack-visibility` | `scripts/search-stack-check.py` | same |
+
+### The deployed runner
+
+The scheduler on **CT 100 (abiba)** runs contracts from
+**`/opt/contract-runner`** via `/etc/cron.d/contract-runner`. That clone is the
+pinned execution copy for every scheduled contract, and it must be kept current
+with `master` by fast-forward. Its `origin` is a local path to the upstream
+working copy, not a network remote.
+
+`daily-health-digest` is **not** in the table above because it has no contract
+file and no mapping — it is dispatched by cron as
+`fm-send.sh ops "run contract: daily-health-digest"` and was, until
+2026-09-25, executed by hand from whichever clone the operator happened to be
+in. Creating its contract file and pinning it to a clone is an open follow-up.
+
+## How the check works
+
+`scripts/revision-preflight.sh <script-path> <clone-path>`:
+
+* resolves the **repo-relative** path of the executing script inside the clone;
+* **fetches** the remote first, so a stale local ref cannot make a stale script
+  look current — bounded by `--fetch-timeout` (default 20s) so a hung remote
+  cannot block a scheduled contract;
+* compares the script's sha256 against `<ref>:<repo-relative-path>`;
+* **fails closed** — a path absent from the ref, an unresolvable ref, or a
+  failed fetch is a failure, never a warning.
+
+### Exit codes and reason classes
+
+The guard distinguishes **"I could not check"** from **"this copy is wrong"**,
+and every non-zero exit prints a machine-readable `REASON=<class>` line before
+the human text, because a warning nobody can classify is not actionable — and
+the flip to `enforce` (below) depends on being able to read these apart.
+
+| exit | `REASON=` | meaning |
+| --- | --- | --- |
+| 0 | — | verified match |
+| 2 | `cannot-verify:fetch-failed` | remote unreachable, failed, or timed out |
+| 2 | `cannot-verify:ref-unresolvable` | `<ref>` does not exist in the clone |
+| 1 | `mismatch:path-absent` | the script does not exist in `<ref>` |
+| 1 | `mismatch:content` | the script differs from `<ref>` |
+| 1 | `mismatch:detached-head` | the clone is on a detached HEAD |
+| 1 | `mismatch:clone-ahead` | local HEAD is strictly ahead of `<ref>` (mid-review) |
+
+`detached-head` and `clone-ahead` are named separately on purpose: they are
+*legitimate* states that merely fail to be "the merged copy", and they are far
+less alarming than a hand-edited file. `clone-ahead` requires HEAD to be
+**strictly** ahead — an uncommitted edit on a commit that *is* the ref is a
+plain `content` mismatch.
+
+## Modes in `contract-run.sh`
+
+| `CONTRACT_REVISION_PREFLIGHT` | Behaviour |
+| --- | --- |
+| unset / **`warn` (default)** | log the refusal and its class, then still report |
+| `enforce` | withhold the verdict, alert, exit `2` |
+| `off` | skip the check entirely |
+
+**The default is `warn`, deliberately.** The guard gates *every* scheduled
+contract, and three legitimate situations would otherwise turn the whole
+fleet's monitoring into withheld verdicts: a clone legitimately ahead of
+`origin/master` mid-review, a detached HEAD, and an offline or failed fetch.
+That is a bigger risk than the staleness the guard exists to catch. `warn`
+keeps the signal loud and classified in every run's log without letting the
+monitoring go dark.
+
+### Criteria for flipping the default to `enforce`
+
+Do not flip it on preference. Flip it when the evidence says the false-refusal
+rate is low enough, as its own small change with its own review:
+
+1. the guard has run across **every scheduled contract** for a sustained period
+   (suggested: 30 consecutive days, or 200+ contract runs) with **zero**
+   `mismatch:*` and **zero** `cannot-verify:*` refusals in the per-run logs;
+2. no `cannot-verify:fetch-failed` arising from ordinary network blips in that
+   window — if the pinned clone's remote is not reliably reachable, `enforce`
+   will withhold rather than report;
+3. the pinned runner clone is demonstrably kept current by fast-forward, so
+   `mismatch:clone-ahead` is a genuine fault rather than routine procedure.
+
+The evidence for the flip is the `REASON=` lines already written into
+`/var/log/contract-runs/`. Until then the default stays `warn`.
+
+## Merge-time sequence (do this whenever this repo merges)
+
+**Baseline as of 2026-09-25:** `/opt/contract-runner` is already
+fast-forwarded to master `9faffe4`, so the pinned runner clone is current
+today. This sequence exists to keep it that way.
+
+After any merge to `master`:
+
+```bash
+# 1. fast-forward the pinned runner clone on CT 100
+git -C /opt/contract-runner pull --ff-only
+
+# 2. confirm it is current and clean
+git -C /opt/contract-runner log --oneline -1
+git -C /opt/contract-runner status --porcelain     # expect no output
+
+# 3. prove a contract runs and reports normally
+CONTRACT_RUN_LOG_DIR=/tmp/preflight-proof \
+  bash /opt/contract-runner/scripts/contract-run.sh search-stack-visibility
+echo "EXIT=$?"     # expect 0, and 'revision-preflight: … matches origin/master'
+```
+
+A contract that reports a `REASON=mismatch:*` refusal here means the runner
+clone is stale or locally edited — fast-forward it rather than reaching for
+`CONTRACT_REVISION_PREFLIGHT=off`.
+
+**Note on untracked files:** git refuses to fast-forward over an untracked file
+even when its content is byte-identical to the incoming version
+(`The following untracked working tree files would be overwritten by merge`).
+A dirty clone will therefore block step 1. Resolve it by removing or stashing
+the untracked paths first — that is exactly what blocked a clone on 2026-09-25.
+
+## Operating notes
+
+* Under the default `warn`, a stale pinned clone still produces verdicts but
+  every run logs the refusal and its class. Read those lines; do not ignore
+  them.
+* Under `enforce`, a stale pinned clone **withholds**. That is the intended
+  failure. Recover by fast-forwarding:
+  `git -C /opt/contract-runner pull --ff-only`.
+* When a contract legitimately changes, land it through the normal branch + PR
+  path and fast-forward the pinned clone. Do not copy files into it by hand.
+* `--no-fetch` exists for offline inspection; it prints that freshness is
+  assumed rather than verified, and it is not used by `contract-run.sh`.

+
+**Dead-man's-switch:** absence of logs must raise an alarm, because that is how
+this went silent for 12 days. That alarm cannot live on the producer — a stopped
+job cannot report that it stopped — so it lives off-host as the
+**`health-log-freshness` contract on CT 100**, which fails when
+`health-logs/gpu/` is older than 12 h. A failed run is also visible in the log
+above, but only the off-host check catches a *missing* run.
+
+**History (2026-09-26, relay-785):** the executor was never lost — only its

+`gpu/` log was silent from `2026-09-14T18:02:03Z`. The schedule was restored and

+1. A key with an empty `models` list (`{}`) or `all-proxy-models` is UNSCOPED — it silently gains ALL models, including cloud. Never create or leave an agent key in this state.
+2. Agent keys MUST carry an **explicit local-only** `models` list.
+3. Granting a cloud model to an agent key requires explicit captain approval and a recorded reason.
+4. The master key always bypasses scoping — it is admin-only, never for inference.

 When reporting findings, separate POLICY observations from FAULT findings:

+### ACCEPTABLE PATTERN
+Agent keys live in `.env` or `.env.vault` files with 600 permissions (koonimo's shape is the canonical example). A plaintext key inside a `config.yaml` or any `config.yaml.bak-*` file is a violation — the backup files are not part of the runtime credential path and are not watched by the scanner, so a key in them is stale clutter that a future reader can mistake for a working key.
+
+**Fix procedure** (when a backup file is found with a plaintext key):
+1. Move the file out of the scanned tree (e.g., `mv /root/.hermes/config.yaml.bak-* /root/hermes-config-backups/`) — do NOT delete the file, just move it so the scanner pattern no longer matches.
+2. Re-run the reachability check to confirm COMPLIANT.
+3. Report the before/after check output and the commands you ran.
+
+**Rationale**: Moving the file preserves history without leaving a credential where a scanner trips over it. Deleting the file loses the historical context. Keeping it in place means the next scan will report it as a finding and waste time re-deciding.
+
 ### POLICY (observation only, not a fault)

+
+### Creating the cloud-enabled key
+
+```bash
+# ALWAYS read the live roster first (key-scoped):
+curl -s -H "Authorization: Bearer <AGENT_KEY>" http://192.168.68.116/litellm/v1/models \
+  | jq -r '.data[].id'
+
+# Then generate a key with an EXPLICIT model list (never empty, never a wildcard).
+# For the cloud-enabled key, list local + cloud. For a standard agent, local only.
+```
+
+Verify after any key change: a standard agent key must return **4 models**, and must NOT return
+any `<prefix>/` cloud model.
+
+### Adding a new cloud provider
+
+1. Add the upstream key to Infisical `infrastructure/production/root`.
+2. Add the deployment(s) to `/opt/inference-harness/litellm_config.yaml` with an `os.environ/` ref
+   and a namespaced `model_name` (`<provider>-<account>/<model>` when a vendor has >1 account).
+3. Restart the `harness-litellm` container.

 ## Purpose
 Auto-fix low-hanging fruit in the graph. No judgment calls — only deterministic Level 1 operations. Escalate anything that needs Kwame's input. When Kwame replies to an escalation, **execute the decision to completion** (update state and timestamps), never leaving a node in review-pending forever.

+### 5. Duplicate-Node Detection (Level 1 — read-only, every run)
+
+The graph's duplicate problem is rarely an agent mistyping a title: it is **recurring writers creating a new
+node per run instead of updating one**. This phase detects that class and reports it. It is read-only and
+**never merges**.
+
+```bash
+python3 /home/hermes/.hermes/scripts/memory_dup_detect.py --json
+```
+Read-only, ~15s over the whole graph, exit 0. That script is the source of truth for the clustering logic —
+do not re-implement it in the prompt or hand-count "duplicates" from titles.
+
+Consume each `items[]` entry's `verdict` field; do not invent your own:
+
+| `verdict` | Meaning | Required action |
+|---|---|---|
+| `WRITER-DEFECT` (`run_family: true`) | ONE scheduled task writes a new node per run | Report the ids, the `agents` (the writer) and `span_days`. **Never merge** — each node is that run's audit record. If the family grew since the last report, say `UNFIXED` and name the writer. |
+| `SAFE-MERGE` | Bodies identical | Still requires an explicit `merge #A into #B` decision from Kwame. |
+| `HUMAN-DECISION` | Same subject, bodies differ | Propose **connect (an edge)**, never merge. |
+
+- **Title overlap alone is not duplication.** Four distinct client workflows of one family (#357-#361) and two
+  different machines' migrations (#1792/#1793) both score high on title tokens while their bodies sit 0.1-0.3
+  apart. Confirm against body similarity before calling anything a duplicate.
+- Report clusters as **candidates for Kwame's decision**, never as established duplicates — a wrong auto-merge
+  destroys distinct content irrecoverably.
+- Per-run history nodes are kept deliberately. Bulk-merging a run family destroys the audit trail the family exists for.
+
 ## Level 2 Escalations (Kwame Decision Required)

 1. **Refresh-suggested stale nodes** flagged with `[REVIEW: refresh]` — refresh or keep? (Archive-suggested nodes are auto-archived under fix 4 and are not escalated.)
-2. **Duplicate Nodes** (same title or >70% title overlap) — Merge or keep?
+2. **Duplicate Nodes** — as detected by fix 5, by `verdict`, never by raw title overlap. `WRITER-DEFECT` is a writer fix (update one canonical node), not a merge decision; `SAFE-MERGE` and `HUMAN-DECISION` clusters are escalated for merge-or-connect.
 3. **Orphan Nodes >90 days old** — Archive or connect?

 ## Reporting Format

+The fixer does **not** send anything. Under the single-egress model (2026-09-21) every report leaves the node

 ## Execution
+**Execution model**: This contract is executed by a host-scheduled cron job (see

+target host and appends the result to `/var/log/contract-runs/<contract>.log`. An
+agent-session acknowledgement (a `done:` line in the ops status log) is NOT
+execution — it only proves the agent read the result and reported it. The actual
+monitoring work happens in the host cron job.
+

 1. **Check PM2 status** — Run `pm2 status --no-color` and parse the table (5th data column = PID, 8th = restarts, 9th = status)
-2. **Check abiba-telegram**:
+2. **Check abiba-telegram** (safe to auto-restart):

   - If status is "stopped" or "errored" → apply Rule 1

   - If status is "stopped" or "errored" → restart (`pm2 restart abiba-zulip` — fully restored)

+Absence of logs raises no alarm. On 2026-09-26 the `gpu/` directory of
+SyslogSolution/health-logs went silent for 12 days unnoticed, because the only
+thing that would have noticed was the job that had stopped. This check lives on
+a DIFFERENT host (CT 100) from the producers, so a producer host that is dead,
+or a schedule that was deleted, still raises an alarm.
+

+Usage:
+    health-log-freshness.py            # check every watched directory

+#   2  the check could not be performed -> REASON=cannot-verify:<class>
+#
+# Every non-zero exit prints one machine-readable line
+#     REASON=<class>
+# followed by the human explanation. The two top-level classes are deliberately
+# distinct: "I could not check" is a different situation from "this copy is
+# wrong", and an operator must never have to guess which they are looking at.
+#
+#   cannot-verify:fetch-failed        the remote could not be reached (or timed out)
+#   cannot-verify:ref-unresolvable    <ref> does not exist in the clone
+#   mismatch:path-absent              the script does not exist in <ref>
+#   mismatch:content                  the script differs from <ref>

+#   mismatch:clone-ahead              local HEAD is ahead of <ref> (mid-review?)
+#
+# FRESHNESS
+#   A guard is only as good as the ref it compares against. On 2026-09-25 a
+#   stale local origin/master made an ancestry check on this fleet report
+#   "unlanded work" for a branch that had in fact merged, and it would equally
+#   have passed a stale script as current. So by default this guard FETCHES the
+#   remote before comparing, bounded by --fetch-timeout so a hung remote cannot
+#   block a scheduled contract. With --no-fetch it compares against whatever the
+#   local ref points at and says so out loud; it never silently assumes
+#   freshness.
+#
+# FAIL CLOSED
+#   An unresolvable path or ref is a FAILURE, never a warning. "Cannot verify"
+#   is precisely the state a stale or hand-edited copy produces, so treating it
+#   as success would defeat the guard. The original draft did exactly that: it
+#   resolved the master revision with
+#   `git show origin/master:$(basename "$SCRIPT")`, which drops the scripts/
+#   prefix, queries the repo root, fails, and exited 0 — passing a script that
+#   exists in no revision at all.
+#
+# WHICH CLONE
+#   Pass the clone the contract is actually executing from. See
+#   docs/contract-execution-pinning.md for which clone each contract pins.

+"""Agent-consumption layer in front of SearXNG + Firecrawl.
+
+Multi-engine aggregation returns results with no dedupe, no filtering and no
+reranking. Measured 2026-09-26 that put bestbuy.com and merriam-webster.com into
+"best practices agent context management", and put four SEO blogs ABOVE the real
+Proxmox forum threads on a precise technical query. Identical queries also ranked
+differently between runs, so the fix has to be deterministic rather than
+dependent on engine mood.
+
+This module turns the raw result list into something an agent can actually use:
+
+  1. DEDUPE      the same page arriving from several engines
+  2. DROP        clear non-answers (homepages, shopping, dictionaries, logins)
+  3. DEMOTE      config-listed low-authority hosts; PROMOTE primary sources
+  4. STABLE SORT so ordering is reproducible run to run
+  5. EXTRACT     page text for the top N under an explicit character budget,
+                 so one call returns usable material instead of a snippet
+  6. EMIT        stable JSON with engine provenance
+
+Policy lives in config/search-ranking.yaml, not in this file.
+
+Usage:
+    search-agent-consume.py "query text"            # JSON to stdout
+    search-agent-consume.py --no-extract "query"    # ranking only, no Firecrawl
+    search-agent-consume.py --explain "query"       # include drop/demote reasons
+
+Exit: 0 ok, 1 no results survived filtering, 2 the layer could not run.

+  measured 2026-09-26 that put bestbuy.com and merriam-webster.com into "best
+  practices agent context management", and put four SEO blogs above the real
+  Proxmox forum threads on a precise technical query. Identical queries also
+  ranked DIFFERENTLY between runs, which is why the layer is deterministic
+  rather than dependent on engine behaviour.
+
+  Pipeline: dedupe -> drop non-answers -> demote content farms / promote primary
+  sources -> stable sort -> extract page text for the top N under an explicit
+  character budget -> stable JSON. Policy lives in config, not code.
+
+  Call it when an agent needs search RESULTS rather than links: it returns usable
+  page text in one call instead of a snippet plus a second fetch.
+
+version: 1.0.0
+---
+
+## Where the policy lives
+
+`config/search-ranking.yaml` — reviewable, no code change needed to adjust:
+
+| key | effect |
+| --- | --- |
+| `non_answer.hosts` / `path_patterns` / `query_keys` / `host_root` | dropped outright |
+| `demote_domains` | ranked below everything, never dropped |
+| `prefer_domains` | promoted above default rank |
+| `ranking.*` | `demote_penalty`, `prefer_bonus`, `multi_engine_bonus` |
+| `extraction.*` | `top_n`, `total_chars`, `per_item_chars`, `timeout_seconds` |
+
+**Demotion, not deletion, for content farms**: a genuinely useful hit is not lost,
+it simply cannot outrank a primary source. Non-answers are dropped because they
+cannot answer a question at all.
+
+## Usage
+
+```bash
+python3 scripts/search-agent-consume.py "query text"              # JSON
+python3 scripts/search-agent-consume.py --no-extract "query"      # ranking only
+python3 scripts/search-agent-consume.py --explain "query"         # + drop reasons
+```
+
+Exit `0` ok, `1` nothing survived filtering, `2` the layer could not run.
+
+## Output shape
+
+Stable JSON:
+
+```json
+{
+  "query": "...",
+  "raw_result_count": 46,
+  "returned_count": 44,
+  "dropped_count": 2,
+  "engines": ["bing", "brave", "duckduckgo", "yandex"],
+  "results": [
+    {"rank": 1, "title": "...", "url": "...", "host": "...",
+     "source_type": "official|code|qa|forum|discussion|web|content-farm",
+     "engines": ["bing"], "score": 100.0,
+     "excerpt": "...", "extraction": "ok|truncated|skipped_budget_exhausted|empty|failed:<Type>"}
+  ],
+  "extraction": {"extracted": 5, "chars_used": 12000, "budget": 12000,
+                 "failures": 0, "seconds": 5.28}
+}
+```
+
+`--explain` adds `dropped: [{url, reason, position}]` so the filter is auditable
+rather than magic.
+
+## Measured before/after (2026-09-26)

+github repo        -> KEEP
+```
+
+**Extraction cost (criterion 4):**
+
+```
+extracted 5 items, 12000 chars used of 12000 budget, 0 failures, 5.28s
+whole run end-to-end: 6.4s wall
+```
+
+## Regression guard
+
+`search-stack-visibility` asserts the layer still ranks correctly: for the fixed
+query set, no `demote_domains` host may appear in the top 3, and the two known
+non-answers must not be returned. Without it this layer could silently rot back
+to raw ordering, which is exactly what happened to the endpoint colours.
+
+## Reachability, and one honest gap
+
+- **Hermes agents** reach it directly: it reads the same `SEARXNG_URL` and
+  `FIRECRAWL_URL` they already use.
+- **pi agents (MCP search server)**: the MCP server's request/response shape is
+  **not ours to change**, so this layer is **NOT** wired into it. That is a real
+  gap, stated rather than claimed as coverage. Closing it would require a change
+  on the MCP side, which is outside this repo.
+
+## Constraints
+
+Does not touch the live SearXNG or Firecrawl service paths. Third-party
+`google cse` is not a hard requirement of this layer — if it 429s, ranking still
+works from the remaining engines. No credential is added or required.

+  instance (http://192.168.68.7:8888) and one extraction service (Firecrawl,
+  http://192.168.68.7:3002). Before this check the stack could degrade to a
+  single engine, or an enabled engine could return nothing at all, without any
+  error surfacing anywhere.
+
+  This contract runs scripts/search-stack-check.py, which:
+    * runs two fixed queries against SearXNG and FAILS when fewer than two
+      engines contribute, printing the contributing engines and every
+      unresponsive_engines entry;
+    * checks extraction by scraping a known page through Firecrawl and FAILS
+      when the returned markdown is empty or the request fails;
+    * reports every silent-zero engine explicitly (enabled, not in
+      unresponsive_engines, contributed no results).
+
+  Multi-engine state (2026-09-25): bing, google cse, brave and yandex
+  contribute on every query. duckduckgo is NOT working: the house egress IP
+  and the VPS fallback egress are both flagged by DuckDuckGo and it reports
+  CAPTCHA. It is left enabled as best-effort coverage so that a recovery shows
+  up as a contribution.
+
+  google cse is a third party's public search-engine id hardcoded in the
+  SearXNG build. Quota and availability are outside our control.
+
+  SCHEDULED: /etc/cron.d/contract-runner on CT 100 (abiba), hourly at :15,
+  via scripts/contract-run.sh search-stack-visibility. Logs land in
+  /var/log/contract-runs/. A failure also raises a firstmate inbox note.
+version: 1.1.0
+---
+
+## Purpose
+
+The fleet has exactly one search endpoint and one extraction endpoint. If
+either degrades, every agent silently loses capability at the same moment.
+The failure mode this contract exists to close is *silent* degradation: a
+query that still returns a page of results while all but one engine have
+stopped contributing, or an enabled engine that answers with zero results and
+raises no error.
+
+## Execution model
+
+The contract is a host-scheduled check, not an agent workflow. It is driven by
+`scripts/contract-run.sh search-stack-visibility` from
+`/etc/cron.d/contract-runner` on CT 100. `contract-run.sh` resolves the
+mapping to `scripts/search-stack-check.py`, runs it under a timeout, writes a
+timestamped log to `/var/log/contract-runs/`, and on non-zero exit raises a
+firstmate inbox note through `bin/fm-inbox.sh`.
+
+## What passing looks like
+
+```
+$ bash scripts/contract-run.sh search-stack-visibility
+Expected engines, enabled (5): ['bing', 'brave', 'duckduckgo', 'google cse', 'yandex']
+queries: 'proxmox backup server' -> contributing: bing, brave, google cse, yandex
+                                    unresponsive: duckduckgo=CAPTCHA
+         'python asyncio tutorial' -> contributing: bing, brave, google cse, yandex
+EXTRACTION: 71016 chars of markdown returned
+VERDICT: PASS -- multiple engines contributing, extraction healthy
+```
+
+## What failing looks like
+
+* A query whose results come from fewer than `SEARCH_CHECK_MIN_ENGINES`
+  engines (default 2) fails and names the engines that did contribute.
+* An extraction request that errors or returns empty markdown fails.
+
+## Silent zeros are reported, not fatal
+
+An enabled, expected engine that contributed nothing **without reporting an
+error** is printed under `SILENT-ZERO ENGINES REPORTED`, and each occurrence is
+annotated `reported, not fatal`.  This is deliberate:
+
+* a general query can legitimately draw zero results from an engine that only
+  fires on certain query shapes, and results are de-duplicated across engines,
+  so a zero does not by itself prove the engine is broken;
+* the run therefore fails only on the two conditions that do prove loss of
+  capability -- fewer than two contributing engines, and a broken extraction
+  leg.
+
+A run can consequently print `VERDICT: PASS` while still listing a silent
+zero.  That is the intended relationship: the zero is *visible*, not *fatal*.
+An engine that fails with an error (for example DuckDuckGo returning CAPTCHA)
+appears in `unresponsive_engines` instead.
+
+## Google coverage is third-party, not ours
+
+The free Google-derived results come from the SearXNG build's built-in
+`google cse` engine.  It uses **a third party's public search-engine id
+hardcoded in the build** (`google_cse.py`, `CX = "partner-pub-8993..."`,
+blackle.com), not a key or id we own.  Its quota and availability are outside
+our control and it can be rate-limited or withdrawn without notice.  No engine
+in this build accepts our own Google Custom Search key; using our own free key
+would require a small wrapper service, which is deliberately **not** built.
+
+## Configuration
+
+Environment overrides (see the script docstring for the full list):
+
+| Variable | Default | Meaning |
+| --- | --- | --- |
+| `SEARXNG_URL` | `http://192.168.68.7:8888` | SearXNG base URL |
+| `FIRECRAWL_URL` | `http://192.168.68.7:3002` | Firecrawl base URL |
+| `SEARCH_CHECK_QUERIES` | `proxmox backup server,python asyncio tutorial` | fixed queries |
+| `SEARCH_CHECK_MIN_ENGINES` | `2` | minimum contributing engines per query |
+| `SEARCH_CHECK_ENGINES` | `bing,brave,google cse,yandex,duckduckgo` | engines a silent zero is reported for |
+| `SEARCH_CHECK_EXTRACT_URL` | Wikipedia Proxmox article | page used for the extraction leg |
+
+## Known residual risk
+
+DuckDuckGo is **not** working.  The house egress IP is CAPTCHA'd by
+DuckDuckGo, and a forward proxy on the VPS (`10.10.10.1:3128`, WireGuard) was
+built as a second egress -- but DuckDuckGo has since flagged the VPS address
+too (HTTP 202 with challenge markers), so DuckDuckGo now reports CAPTCHA on
+both paths.  It is left enabled as best-effort coverage: if DuckDuckGo
+unflags either address it will show up as a contribution, and until then it is
+visible in `unresponsive_engines` every run.  It is never a required engine.
+
+The VPS forward proxy remains a real service (`/opt/fwd-proxy`,
+`restart: unless-stopped`, healthy healthcheck, Docker enabled at boot) so the
+second egress path is available for any engine that benefits from it in future.

+"""Regression test for the fallback_providers list-shape crash in audit-hermes-config.py.
+
+WHY THIS FILE EXISTS: audit-hermes-config.py assumed `fallback_providers` was always a dict
+(single provider). Two live agents (koby, koonimo) carry it as a LIST of dicts (one entry per
+fallback), so the script crashed with:
+
+    File "audit-hermes-config.py", line 211, in audit
+        fb.get("provider") == "deepseek",
+    AttributeError: 'list' object has no attribute 'get'
+
+Both are REAL agent configs, so this is not a malformed-input case — the script simply could not
+audit two of the four agents it exists to audit. Until fixed, the key-hygiene check had no
+coverage for half the fleet while appearing to run.
+
+These tests execute the real CLI (`python3 audit-hermes-config.py <config>`) and assert:
+1. A config whose `fallback_providers` is a LIST of valid dicts does NOT crash (exit code is 0 or 1,
+   never a traceback/AttributeError).
+2. A config whose `fallback_providers` contains a MALFORMED entry (a list element that is not a
+   mapping) reports a VIOLATION naming the offending entry, NOT an uncaught exception.
+3. The dict shape still works (existing tests must stay green).
+
+No network, vault, or SSH access is required.

+"""Behavioural tests for zulip-monitor.sh kagentz C1/C3 legs and the Result verdict.
+
+WHY THIS FILE EXISTS: the 2026-09-19 kagentz A2A outage was correctly detected
+by the monitor (C1 returned 000, the run logged an issue) but the lane's own
+summarization in ops.status wrote "OK" with the note "A2A server DOWN — expected
+(no credentials configured)". The optimistic verdict came from the lane, not the
+script. The fix adds a C3 public-access-path leg and makes the Result line say
+"INCIDENT" when issues are found, so the lane can quote it verbatim.
+
+CONTRACT UNDER TEST:
+  * C1 (A2A liveness, no credential): 000 → INCIDENT.
+  * C3 (public access path, no credential): 502 → INCIDENT, 000 → INCIDENT,
+    200/302/401 → alive.
+  * Result verdict: when ISSUES > 0, the log's Result line says "INCIDENT",
+    not just "issues found".
+  * Healthy control: C1 401 + C3 302 → 0 issues, "all healthy".
+
+HOW: behavioural execution using the sandbox pattern already in this repo
+(tests/test_mumuni_monitor_removal.py). The sandbox copies the shipped monitor
+verbatim, rewrites only its LOG constant, and runs it with stub ssh/curl on
+PATH. Each test asserts from the run's own log/verdict, not from file text.

 ## Execution
+**Execution model**: This contract is executed by a host-scheduled cron job (see
+`scripts/contract-run.sh`). The cron job runs the monitoring script directly on the
+target host and appends the result to `/var/log/contract-runs/<contract>.log`. An
+agent-session acknowledgement (a `done:` line in the ops status log) is NOT
+execution — it only proves the agent read the result and reported it. The actual
+monitoring work happens in the host cron job.

 ### Liveness rule (scoped)

-Any HTTP response proves the service is ALIVE. For auth-gated endpoints (Zulip API, Tanko gateway), a 401/403 redirect or status means the service answered — report the code, never "down". Only a failed CONNECTION (curl status 000, timeout, refused) is a failed probe.
+Any HTTP response proves the service is ALIVE. For auth-gated endpoints (Zulip API, Tanko gateway), a 401/403 redirect or status means the service answered — report the code, never "down". Only a failed CONNECTION (curl status 000, timeout, refused) is a failed probe. **Proxy-fronted exception:** a reverse proxy's `502`/`504` (upstream refused/unreachable) is not the backend answering — for proxy-fronted public endpoints such as `https://kagentz.sysloggh.net/` (C3), treat it as DOWN.

 **STANDING PROBE RULES (2026-09-14, from defect report 1150.msg):**
-1. **Any HTTP status means ALIVE.** 200, 301, 302, 401, 403, 404 all prove the service answered — report the code, never "down". A redirect is not a failure. Only a failed CONNECTION (curl status 000, timeout, refused) is a failed probe.

 2. **A failed probe is never a service verdict.** Print `probe-failed: <target> <kind>` naming the exact URL/host/port and the failure kind (timeout, refused, no-route, dns), retry once at a longer timeout, and only then report.
 3. **Say which probe produced each number.** "API: 000" is unusable; "API https://chat.sysloggh.net/api/v1/server_settings -> connection timeout after 10s (retried at 25s: also timeout)" is actionable.
