fix(daily-infra-report): resolve PVE token from env; make a dead probe non-silent
The Proxmox leg of the daily digest has been reporting NOTHING while exiting 0. Root cause: the auth header was a literal placeholder string, AUTH = "Authorization: PVEAPIToken=«vault: infrastructure/production PVE_API_TOKEN»" which was sent verbatim. The API rejected it, pve_get() returned None, and the report rendered node_count=0 / nodes_online=0 with pve_probe_status='unreachable' while still exiting 0. A monitoring gap that looks like a healthy run. Also: the vault key is PVE_TOKEN, not PVE_API_TOKEN, so even reading os.environ by the old name would not have found it. Fixes: * pve_auth() resolves the token at call time from PVE_TOKEN (injected by 'infisical run --env=prod'). Nothing is hardcoded; a missing token raises. * pve_get() builds the command inside its try block, so a missing token degrades to None instead of escaping as an unhandled exception. * PROBE_FAILURES records an unreachable node/resources probe. Probe failures are deliberately separate from DEGRADED_LEGS: a missing credential stays exit 0 (existing intent), but a probe with no data now exits 1 in both the report and --json paths, so it cannot pass unnoticed. Measured effect on the live host: pve_probe_status unreachable -> ok, node_count 0 -> 5, nodes_online 0 -> 5, total_vms 0 -> 22, running_vms 0 -> 22. Tests: 4 new regression tests; all 4 fail against the pre-fix script and pass after, and the 3 pre-existing tests still pass (7/7). Not fixed here (needs the captain): the email leg fails with '534 5.7.9 Application-specific password required' - EMAIL_PASSWORD in the vault is not a valid Gmail app password for jtabiri@gmail.com. That is a credential action, not a code change.

+# 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 (.8, .110, .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
+
+- **Every 4 hours** (2, 6, 10, 14, 18, 22 UTC at :35): Scheduled cron check while Abiba is running
+- **On `agent-health` command**: Run on-demand and report to user
+- **On critical alert**: Escalate to relay message immediately

+## Host Filesystem Thresholds (HOST nodes — separate bands from guest bands)
+
+Host filesystems have their own risk profile and their own bands. A host root near full is a real risk (backup staging writes to it, thin-pool metadata pressure), a media volume near full is a capacity decision for the owner, and the backup datastore near full breaks backups. These are **report-only** — no automatic deletion of media or datastore content ever.
+
+| Level | Threshold | Response | Escalation |
+|-------|-----------|----------|------------|
+| **HOST-WARN** | 85% | Name the volume + % + absolute free space in the scan output | None |
+| **HOST-AMBER** | 90% | Name the volume + % + absolute free space; flag for owner attention | Zulip DM to owner (state-change only) |
+| **HOST-RED** | 95% | Name the volume + % + absolute free space; **media volumes: "capacity decision — owner to decide"; pbs-datastore/host-root: "immediate owner attention"** | Zulip DM + channel alert (state-change only) |
+
+**Escalations are STATE-CHANGE driven, not per-run.** A volume alerts ONCE when it enters a higher band (GREEN->WARN, WARN->AMBER, AMBER->RED) and ONCE when it drops back down (a recovery notice). While a volume stays in the same band, it is reported in the scan output only — no DM, no channel alert. This prevents the same 96% easystore2 from re-DMing the owner on every 6-hour scan and drowning a real warning in noise.
+
+**State lives in a small JSON state file:** the scanner resolves it to an absolute path from the script's location — `$(dirname "$0")/state/host-disk-bands.json` (i.e., the `state/` directory next to the `scripts/` directory in the prose-contracts repo). The state file is gitignored runtime state — the scanner creates it on first run. Keyed by `host/volume` → last-seen band. The scanner reads the prior band, compares to the current band, and DMs only on a transition. The state file is written after every scan. (Chosen over a periodic digest because the scan already runs every 6h and a transition is genuinely new, actionable state that warrants an immediate DM — but only once.)
+
+**Volume naming rule:** Every host line MUST name the volume and what lives on it. Example output:
+
+```
+storepve /media/easystore2 (media): 96% (3.5T/3.7T, 177G free) -> HOST-RED
+storepve /media/reanim (media): 86% (797G/932G, 135G free) -> HOST-WARN
+storepve /media/mediastore (media): 77% (5.3T/7.3T, 1.6T free) -> GREEN
+storepve /dev/mapper/pve-root (host-root): 81% (73G/94G, 17G free) -> GREEN
+storepve tank (pbs-datastore): 1% (128K/12T, 12T free) -> GREEN
+```
+
+**First-run behavior:** When the state file does not yet exist (first scan), the current band of every volume is recorded as the baseline WITHOUT alerting — a first run would otherwise DM every already-elevated volume at once. From the second run onward, transitions alert.
+
+**Action classes by volume type:**
+- **host-root**: near full = real risk (backup staging, thin-pool metadata, journald). HOST-AMBER or above → owner must investigate.
+- **media** (/media/*): near full = capacity decision for the owner. HOST-AMBER or above → report only, never auto-delete.
+- **pbs-datastore** (tank, ZFS): near full = breaks Proxmox Backup Server. HOST-RED → escalate immediately.
+
+**Justification (measured 2026-09-15, firstmate):** storepve (192.168.68.6) shows /media/easystore2 at 96%, /media/reanim at 86%, /dev/mapper/pve-root at 81%, and tank at 1%. The previous scan reported "0/19 guests >80%, no GC action needed" while easystore2 sat at 96% — the host filesystems were printed but never banded and never acted on. Two incidents this weekend (amdpve host root filled during container backup staging, acerpve root went read-only when its thin pool errored) showed the host filesystem is the thing that breaks, not the guest's.

+## Model Access Tiers (2026-09-20)

+| Tier | Models | Who gets it |
+|------|--------|-------------|
+| **Local** | `strix-moe`, `gpu-dense`, `gpu-vision`, `syslog-auto` | All standard agent keys (tanko, mumuni, koby, koonimo, abiba-pi) |

+
+**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.

 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.

 - HTTP 307 redirect on `/mcp` → use `/mcp/` (trailing slash) or `/mcp-rest/` endpoints
 - `api_mode: responses` in Hermes appends `/v1/responses` to base_url → **base_url must end at `/v1`, never `/responses`** (double-path bug)

-### Migration Path
-When LiteLLM is upgraded to a version supporting per-key MCP grants:
-1. Grant agent keys `mcp_servers: ["ra_h_os"]`
-2. Update Hermes `mcp_servers.ra-h-os.url` from `http://192.168.68.65:3100/mcp` → `http://192.168.68.116:4000/mcp/`
-3. Add `headers: {x-litellm-api-key: "Bearer $LITELLM_API_KEY"}` to MCP config
+### Migration Path (COMPLETED 2026-09-18)
+Per-key MCP grants are now supported:
+1. ✅ Agent keys granted MCP access via `allowed_mcp_servers` field
+2. ✅ Hermes `mcp_servers.litellm.url` set to `https://litellm.sysloggh.net/mcp`
+3. ✅ `headers: {x-litellm-api-key: "Bearer <literal_key>"}` added to MCP config

+## Cloud Provider Consolidation (2026-09-20)
+
+CT 116 LiteLLM (Community v1.99.1) fronts **7 upstream providers** in addition to the local
+GPU models. Added 2026-09-20 — 47 cloud deployments, 51 unique model names total.
+
+### 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 |
+|--------|----------|------|--------------|
+| `openrouter/` | OpenRouter | API key | `OPENROUTER_API_KEY` |
+| `deepseek/` | DeepSeek direct | API key | `DEEPSEEK_API_KEY` |
+| `google/` | Google AI Studio (Gemini) | API key | `GEMINI_API_KEY` |
+| `qwen-payg/` | QwenCloud / DashScope (pay-as-you-go) | API key | `DASHSCOPE_PAYG_KEY` |
+| `qwen-plan/` | QwenCloud / DashScope (token plan) | API key | `DASHSCOPE_PLAN_KEY` |
+| `tencent-payg/` | Tencent TokenHub (PAYG) | Bearer token | `TENCENT_PAYG_KEY` |
+| `tencent-plan/` | Tencent TokenHub (Plan) | Bearer token | `TENCENT_PLAN_KEY` |
+
+All cloud `api_key` fields use `os.environ/<NAME>` — the 7 secrets live in Infisical
+(project=`infrastructure`, env=`production`, folder=`root`) and are injected into the
+`harness-litellm` container at start. **No literal cloud keys in `litellm_config.yaml`.**
+
+### 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.
+5. Update this table and the access-tier section.

+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.

+# Implements infrastructure-monitoring.prose.md (check-health section)
+#
+# Legs: Grafana, Prometheus, LiteLLM, PVE API (5 nodes), GPU exporters,
+#       Docker Stats, PVE Exporter
+#
+# Design:
+# - Every target, port, path, and expected status is defined in code
+# - Liveness rule: any HTTP status = ALIVE for auth-gated/redirect endpoints;
+#   only connection failures (000/timeout) = probe-failed
+# - Bare-200 rule: expected status must match exactly (200); anything else = alert
+# - PVE API uses -k flag (self-signed certs), probes /api2/json/version
+# - Docker Stats and PVE Exporter bind to 127.0.0.1 on CT 116, probed via SSH
+#   with one retry at longer timeout (25s connect, 30s max) to distinguish
+#   transient timeout from host-down
+# - Non-zero exit naming every failed target; no "OK" summary when any leg failed
+#
+# Output shape per leg:
+#   ✅ <name>: alive
+#   🔴 <name>: probe-failed: <host>:<port> (expected <pattern>) (<kind>)
+#
+# Failure kinds: timeout | refused | tls | unexpected:<code> (printed in the failure line)

+"""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.
+
+Environment overrides (all optional):
+  SEARXNG_URL         default http://192.168.68.7:8888

+kind: function
+name: search-stack-visibility
+description: >
+  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.

+"""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.
