 ## 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.

+  Produces the daily infrastructure dashboard for the whole estate — 5 Proxmox
+  nodes, every VM/CT, Zulip, LiteLLM, Docker hosts, storage and NFS — and mails
+  it as an HTML report.
+
+  Dispatched by cron on CT 100 (abiba) at 10:30 UTC as a firstmate message to
+  the ops lane, which executes the producer below. Until 2026-09-25 this ran
+  with NO contract file at all, which is why the choice of execution copy was
+  silently the operator's rather than the contract's.
+
+  EXECUTION IS PINNED. The producer must be run from the clone named under
+  "Execution pinning" — not from an agent working copy.
+
+  Exit-code semantics (as they actually behave, verified 2026-09-25):
+    * missing PVE_TOKEN, or an unreachable Proxmox probe -> exit 1 + alert
+    * missing or rejected Zulip credential -> exit 1 (delivery is the only
+      output path, so it is a real failure, not a degraded leg)
+    * delivery failure -> exit 1, and the report body is printed AND persisted
+      so the content is never swallowed
+
+version: 2.0.0
+---
+
+## 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 |

+| `litellm` | object | inference checks |

+| `agents` | object | per-agent health |

+  "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 \

+
+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.

+# 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`.

 ## Execution

+
+**Dead-man's-switch:** absence of logs must raise an alarm, because that is how

+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.

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

+
+## Model Access Tiers (2026-09-20)
+
+CT 116 hosts two **access tiers** of model. Tier membership is enforced per virtual key via that key's `models` allowlist.
+
+| Tier | Models | Who gets it |
+|------|--------|-------------|
+| **Local** | `strix-moe`, `gpu-dense`, `gpu-vision`, `syslog-auto` | All standard agent keys (tanko, mumuni, koby, koonimo, abiba-pi) |
+| **Cloud** | 47 provider models: `openrouter/*`, `deepseek/*`, `google/*`, `qwen-payg/*`, `qwen-plan/*`, `tencent-payg/*`, `tencent-plan/*` | **Only** the designated cloud-enabled key (captain decision) |
+
+**Rules:**
+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.

+### Provider map (per-account namespacing)
+
+Two accounts on the same vendor get **distinct prefixes** so billing, rate limits, and keys
+stay separate:
+
+| Prefix | Upstream | Auth | Vault secret |

+### Access tiers (MUST be enforced per key)
+
+| Tier | Model names | Granted to |
+|------|-------------|------------|
+| **Local** | `strix-moe`, `gpu-dense`, `gpu-vision`, `syslog-auto` | every standard agent key |
+| **Cloud** | the 47 provider models (`<prefix>/<model>`) | **only** the designated cloud-enabled key |
+
+> ⚠️ **Community-edition caveat:** LiteLLM Community does not restrict wildcard access groups
+> the way Enterprise does. Access is decided by each key's explicit `models` list. A key with
+> `models = {}` or `models = ["all-proxy-models"]` sees **all** models — a silent cloud leak.
+> Every key MUST carry an explicit list. The master key always bypasses scoping (admin-only).
+
+### 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.
+4. Grant the model to the cloud-enabled key ONLY (explicit list) — never to agent keys without
+   captain approval.

 ## 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.

 **Archive candidates are identified by the fix 3 query's `suggested_action = 'archive'` branch** (the `ELSE 'archive'` case: anything not an infrastructure/skill/documentation/strategic/audit type).

+### 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 reports to Kwame via this Zulip DM:
+The fixer does **not** send anything. Under the single-egress model (2026-09-21) every report leaves the node
+through Mumuni's gate (`comms_drop.py` for the queue, `comms_gate.py` to release and read-back verify), so

 ## 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 "online" → pass
   - If status is "stopped" or "errored" → apply Rule 1
-   - If restarts > 5 → alert owner
+   - If restarts > 1000 → apply Rule 2 (crash-loop guard)
 3. **Check abiba-zulip** (live Zulip bridge, heartbeating):

   - If status is "stopped" or "errored" → restart (`pm2 restart abiba-zulip` — fully restored)
   - If restarts > 5 in last hour → alert owner with full diagnostics
-4. **Log results** — Append to `SyslogSolution/health-logs/pm2/{timestamp}.md` in Gitea (not knowledge graph — hard rule)

+### Schedule
+Cron `0 20 * * *` on the **storepve HOST** (192.168.68.6) = 20:00 America/New_York local = **00:00 UTC**.
+
+**NOTE**: The closed PR #116 said "20:00 UTC" — this is WRONG by four hours. Do not copy it.
+
+### What Actually Runs
+Host script `/usr/local/bin/pbs-gc.sh` runs `pct exec 107 -- proxmox-backup-manager garbage-collection start storepve-datastore`.
+
+**IMPORTANT**: The tool `proxmox-backup-manager` exists only inside CT 107 (where the PBS server runs). The storepve host has only `proxmox-backup-client`. This is why the job had never worked before 2026-09-19 00:00 UTC.

+- **Datastore**: CT 107's `/mnt/pbs-backup` on the storepve ZFS dataset `/tank/pbs-backup` (pool `tank`, ~11T free)
+- **NOT** `/media/easystore2` (media library, 3.7T, 96% used — separate volume)

+- **FAILS** if `last-run-endtime` is older than 48 hours
+- Reports age in hours and pending-bytes
+
+**All six verdict shapes** (exactly as emitted by the script):

+2. **Stale** (GC ran >48h ago):
+   `🔴 PBS GC: stale (last run 49h ago, pending-bytes: 1048576 B)`

+3. **Probe-failed: empty read** (000/timeout/unreadable):
+   `🔴 PBS GC: probe-failed: storepve:192.168.68.6 (expected JSON, got 000)`

+"""Health-log freshness watchdog (dead-man's-switch).
+
+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.
+
+It asks the Gitea API for the newest commit touching each watched directory and
+fails when that commit is older than the directory's threshold.
+
+Usage:
+    health-log-freshness.py            # check every watched directory
+    health-log-freshness.py --json     # machine-readable output
+
+Exit: 0 = all fresh, 1 = at least one stale or unreachable, 2 = check could not run.
+
+Environment:
+    GITEA_URL            default https://git.sysloggh.net
+    GITEA_TOKEN          API token (falls back to GITEA_PAT, then to the token

+#   --no-fetch             Do not refresh the ref first (see FRESHNESS)

+#   -h, --help             Show this help
+#
+# Exit codes:
+#   0  the executing script byte-matches <ref>:<repo-relative-path>
+#   1  the copy is NOT the merged one  -> REASON=mismatch:<class>
+#   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:detached-head            the clone is on a detached HEAD
+#   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.

+  4. STABLE SORT so ordering is reproducible run to run
+  5. EXTRACT     page text for the top N under an explicit character budget,

+"""Search-stack visibility check.
+
+The fleet shares one SearXNG instance (search) plus one extraction service
+(Firecrawl).  A broken search stack used to fail silently: one engine answered
+and nobody could tell that the other engines had stopped contributing, or that
+an enabled engine was returning nothing at all without reporting an error.
+
+This check makes those failures visible and non-zero:
+
+  * runs two fixed queries against SearXNG; FAILS when fewer than two engines
+    contribute to a query, printing the contributing engines and every
+    ``unresponsive_engines`` entry;
+  * FAILS when a known page cannot be extracted to non-empty markdown through
+    Firecrawl;
+  * reports every *silent zero* engine explicitly -- an engine that is enabled,
+    is eligible for the query category, is not listed in
+    ``unresponsive_engines``, and still contributed no results.
+
+Exit code 0 = healthy, 1 = degraded, 2 = the check could not run at all.

+  Agent-consumption layer in front of SearXNG + Firecrawl. Raw 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, 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)
+
+Fixed query set. Relevance judged per query, not by impression.

+| 5-9 | forum.proxmox.com x2, voxfor, github, gist | forum.proxmox.com, serverfault, forum.proxmox.com, reddit |
+
+The primary sources moved from positions 5-9 to 1-4.
+
+**Rule proof** (`--explain`, and a direct check of the classifier):
+
+```
+DigitalOcean docs  -> KEEP   (a '/products/' path rule was REMOVED after the
+                              before/after run caught it dropping this page)
+Best Buy           -> DROP   shopping_or_dictionary_host
+Merriam-Webster    -> DROP   shopping_or_dictionary_host
+bare homepage      -> DROP   navigational_host_root
+proxmox.com home   -> KEEP   (preferred host root: a repo/docs front door is
+                              legitimately the answer)
+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.

+  Makes the shared search stack observable. Every agent reaches one SearXNG
+  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.

 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.
