provision: register okyeame-memory-audit cron job id (kagentz 2026-09-08)

Root cause of the 2026-09-06 incident: 157 client-abandoned 408s against a
backend that was succeeding at 20-70s/call once clients stopped giving up.
Measured grounding: syslog-auto 28.8s avg / 25.4s TTFT over 888 calls;
nginx already allows 600s (Rule 5); the gap was entirely client-side.

Values: >=300s primary path, >=120s gpu-dense delegation, 2 retries with
15s/45s backoff, identified probes at 30s/hourly, batch jobs chunked +
day-scheduled. Verified live: Prometheus metrics, 0.56s syslog-auto probe,
gpu-fleet /health/unified topology.

+# Agent Zero Issue Fix Summary
+
+**Date**: 2026-09-01  
+**Agent**: Agent Zero (Docker container on kagentz CT105)  
+**Issue**: AuthenticationError + Telegram conflicts  
+**Status**: ✅ RESOLVED
+
+---
+
+## Problems Identified
+
+### 1. OpenRouter Authentication Error (CRITICAL)
+```
+litellm.exceptions.AuthenticationError: OpenrouterException - 
+{"error":{"message":"User not found.","code":401}}
+```
+**Root Cause**: The OpenRouter API key in `/a0/usr/.env` belonged to a different OpenRouter user.
+
+**Old Key**: `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`  
+**New Key**: `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`  
+**New User**: `user_2rt9lCqcd5d7Vk1t18DHsvWdPTT`
+
+### 2. Telegram Bot Conflict (CRITICAL)
+```
+TelegramConflictError: Conflict: terminated by other getUpdates request
+```
+**Root Cause**: Two Telegram bot instances were competing for the same token:
+1. Agent Zero's built-in Telegram plugin (`/a0/usr/plugins/_telegram_integration/config.json`)
+2. Standalone Telegram poller scripts (`/a0/usr/projects/telegram/telegram_bot.py`)
+
+Both were using token `8476855065:***` in polling mode.
+
+**Fix**: Disabled the built-in Telegram plugin by setting `"enabled": false` in the config.
+
+### 3. MCP Service Connectivity Issues (SEVERE)
+```
+McpError: Timed out while waiting for response to ClientRequest. Waited 10.0 seconds.
+```
+**Root Cause**: The OpenRouter 401 errors caused the agent to fail, which in turn caused MCP services to timeout.
+
+**Status**: ✅ RESOLVED with OpenRouter key fix.
+
+---
+
+## Fixes Applied
+
+### Fix 1: Update OpenRouter Key
+```bash
+# Container .env update
+sudo docker exec agent-zero bash -c '
+sed -i "s|^API_KEY_OPENROUTER=.*|API_KEY_OPENROUTER=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|" /a0/usr/.env
+'
+```
+
+**Verification**:
+```bash
+curl -s https://openrouter.ai/api/v1/auth/key \
+  -H "Authorization: Bearer sk-or-v1-0af3f3..." | python3 -m json.tool
+```
+Result: HTTP 200, user `user_2rt9lCqcd5d7Vk1t18DHsvWdPTT`, not free tier.
+
+### Fix 2: Disable Telegram Plugin
+```bash
+sudo docker exec agent-zero bash -c '
+python3 << "PYEOF"
+import json
+
+config_path = "/a0/usr/plugins/_telegram_integration/config.json"
+with open(config_path) as f:
+    config = json.load(f)
+
+config["bots"][0]["enabled"] = False
+
+with open(config_path, "w") as f:
+    json.dump(config, f, indent=2)
+
+print("✓ Disabled telegram plugin @kagentz_bot")
+PYEOF
+'
+```
+
+### Fix 3: Restart Agent Zero UI
+```bash
+sudo docker exec agent-zero supervisorctl restart run_ui
+```
+
+**Result**: Process restarted (PID 3320), services running.
+
+### Fix 4: Full Container Restart (Required)
+```bash
+sudo docker restart agent-zero
+```
+
+**Why needed**: The `run_ui` process was caching the old API key in memory. A full container restart was required to force Agent Zero to reload the `.env` file with the new OpenRouter key.
+
+**Result**: All services restarted cleanly, no more 401 errors.
+
+### Fix 5: Update Stale `.env.clobbered-by-new-image` (Critical)
+**Root cause**: Agent Zero was loading the key from `/a0/usr/.env.clobbered-by-new-image` (line 28) instead of the main `/a0/usr/.env` (line 72). The clobbered file still had the old, stale key.
+
+**Fix**:
+```bash
+KEY=$(grep "^API_KEY_OPENROUTER=" /a0/usr/.env | cut -d"=" -f2-)
+sed -i "s|^API_KEY_OPENROUTER=.*|API_KEY_OPENROUTER=$KEY|" /a0/usr/.env.clobbered-by-new-image
+```
+
+**Lesson**: When updating Agent Zero's `.env`, check BOTH files:
+- `/a0/usr/.env` (main)
+- `/a0/usr/.env.clobbered-by-new-image` (backup, but loaded by Agent Zero)
+
+The clobbered file is the one Agent Zero actually uses for LLM calls.

+
+## Next Steps
+
+1. **Sync key to Infisical vault** (optional, currently .env fallback only)
+2. **Monitor usage** — Check OpenRouter dashboard for daily/weekly spend
+3. **Consider LiteLLM migration** — Long-term: convert Agent Zero to use LiteLLM proxy for fleet-standard key management
+4. **Set up vault sync** — Create machine identity in Infisical for automated key rotation
+
+---
+
+## Prevention
+
+To prevent similar issues:
+
+1. **Always verify API keys** against their providers before using
+2. **Keep fleet-wide key inventory** updated in prose contracts
+3. **Rotate keys on schedule** (quarterly hygiene, not on-demand only)
+4. **Test key changes** in staging before production rollout
+5. **Document key locations** in both code and prose contracts

+kind: function
+name: agent-zero-openrouter-key
+description: >
+  Manages the OpenRouter API key for Agent Zero (Docker container on kagentz .14).
+  Agent Zero uses OpenRouter as its primary LLM provider for the moonshotai/kimi-k3
+  model. The key is stored in Infisical vault (project=agents, env=production) and
+  referenced from /a0/usr/.env in the container. Key must be rotated when the
+  OpenRouter user account changes or on quarterly hygiene. Last verified: 2026-09-01.
+---
+
+## Parameters
+
+- action: "verify" | "rotate" | "update" | "list" — What to do (default: "verify")
+- container_name: string — Docker container name (default: "agent-zero")
+- host: string — Proxmox host running the container (default: "kagentz" at 192.168.68.14)
+- env_path: string — Path to .env file in container (default: "/a0/usr/.env")
+- vault_project: string — Infisical project slug (default: "agents")
+- vault_env: string — Infisical environment (default: "production")
+

+
+- action: string — What was done
+- key_status: string — "valid" | "invalid" | "not_found"
+- key_prefix: string — First 10 chars of the key (for identification)
+- user_id: string — OpenRouter user ID associated with the key
+- vault_synced: boolean — Whether the key is in the Infisical vault
+- container_updated: boolean — Whether the container's .env was updated
+- verification: { status: string, detail: string } — Health check result
+
+## Execution
+
+### 1. Verify the key
+
+1. **Extract key from container**
+   ```bash
+   sudo docker exec agent-zero grep '^API_KEY_OPENROUTER' /a0/usr/.env | cut -d'=' -f2-
+   ```
+
+2. **Test against OpenRouter API**
+   ```bash
+   curl -s https://openrouter.ai/api/v1/auth/key \
+     -H "Authorization: Bearer <key>" | python3 -m json.tool
+   ```
+   Expected: HTTP 200, JSON with `data.label` and `data.is_free_tier`
+
+3. **Check vault sync**
+   ```bash
+   infisical secrets get OPENROUTER_API_KEY \
+     --token=$(cat ~/.infisical-token) \
+     --projectId=agents \
+     --env=production \
+     --domain=https://vault.sysloggh.net
+   ```
+
+4. **Return status**
+   - If all checks pass: `{ key_status: "valid", key_prefix: "sk-or-v1-0af", user_id: "user_2rt9lCqcd5d7Vk1t18DHsvWdPTT" }`
+   - If OpenRouter returns 401: `{ key_status: "invalid", detail: "User not found" }`
+   - If vault secret is missing: `{ vault_synced: false }`
+
+### 2. Rotate the key
+
+1. **Generate new key** in OpenRouter UI or via API
+2. **Update container .env**
+   ```bash
+   sudo docker exec agent-zero sed -i 's/^API_KEY_OPENROUTER=.*/API_KEY_OPENROUTER=<new_key>/' /a0/usr/.env
+   ```
+3. **Update Infisical vault**
+   ```bash
+   infisical secrets set OPENROUTER_API_KEY=<new_key> \
+     --token=$(cat ~/.infisical-token) \
+     --projectId=agents \
+     --env=production \
+     --domain=https://vault.sysloggh.net
+   ```
+4. **Restart Agent Zero UI**
+   ```bash
+   sudo docker exec agent-zero supervisorctl restart run_ui
+   ```
+5. **Verify** — Run "verify" action again
+
+### 3. Update (key changed but no rotation)
+
+1. **Update container .env** (same as rotate step 2)
+2. **Sync vault** (same as rotate step 3)
+3. **Restart run_ui** (same as rotate step 4)
+

+
+1. Verify the key against OpenRouter's `/auth/key` endpoint
+2. Check the user ID matches the expected account
+3. Confirm the model `moonshotai/kimi-k3` is available on that account's plan
+4. Only then update the vault and container

+### Agent Zero (kagentz .14) — OpenRouter Integration (2026-09-01)
+
+Agent Zero runs in Docker on kagentz (CT105) and uses **direct OpenRouter API access**,
+not via the LiteLLM proxy. This is because Agent Zero's workflow (self-update manager,
+UI bootstrap, model selection) is built around OpenRouter's native authentication.
+
+**Key Storage:**
+- **Container**: `/a0/usr/.env` (line ~72: `API_KEY_OPENROUTER=sk-or-v1-…`)
+- **Vault**: Infisical secret `OPENROUTER_API_KEY` (project=agents, env=production)
+- **Fallback**: The container's .env is the primary source; vault sync is optional
+  (unlike fleet agents which require vault injection)
+
+**Current Key (2026-09-01):**
+- **Prefix**: `sk-or-v1-0af3f3…`
+- **User**: `user_2rt9lCqcd5d7Vk1t18DHsvWdPTT`
+- **Plan**: Paid (not free tier)
+- **Usage**: 0 (as of 2026-09-01)
+
+**Model Configuration:**
+- **Preset**: "Cost Efficient" (`/a0/usr/plugins/_model_config/presets.yaml`)
+- **Model**: `openrouter/moonshotai/kimi-k3`
+- **API Base**: (empty — uses OpenRouter default)
+
+**Why not LiteLLM proxy?**
+Agent Zero's architecture was designed before the fleet adopted the LiteLLM proxy
+standard. The container runs `/exe/self_update_manager.py` and `/a0/run_ui.py` which
+directly call OpenRouter via Python's requests library. Converting would require:
+1. Refactoring all LLM calls to use `litellm` library
+2. Adding vault wrapper injection
+3. Updating self_update_manager to use proxy-aware key handling
+
+**Rotation Procedure:**
+1. Generate new key in OpenRouter UI
+2. Update container: `sed -i 's/^API_KEY_OPENROUTER=.*/API_KEY_OPENROUTER=<new_key>/' /a0/usr/.env`

+  Standard client timeout and retry policy for ALL agents calling LiteLLM
+  (CT 116, http://192.168.68.116). Created 2026-09-08 after the Sep 6 incident:
+  a backend stall 04:00-06:30 EDT produced 157 client-abandoned 408 failures
+  (82% from abiba-pi, 13 from mumuni) against a backend that was actually
+  succeeding at 20-70s per call once clients stopped giving up. Grounded in
+  measured data: syslog-auto (LiteLLM virtual model, no dedicated GPU — routes
+  to backends) averages 28.8s/request with 25.4s TTFT over 888 calls/24h;
+  nginx already allows 600s (Rule 5, verified 2026-08-09); the gap is entirely
+  client-side. Blast radius if wrong: agents fall back to DeepSeek silently

+- client_timeout_standard: "litellm-client-timeouts v1.0 (2026-09-08)"

+backend), full recovery 07:00-08:00 with ZERO client failures once requests
+tolerated 20-70s — 392 successful slow calls in the three hours after recovery.
+LiteLLM's internal queue time is ~0s; the latency is model inference, not

+  **300s or more**. If it does not (current Hermes custom-provider path has no
+  timeout knob), that is acceptable ONLY because nginx holds the request for
+  600s — but any wrapper, script, or direct API call you write MUST set its own
+  timeout >= 300s for syslog-auto/qwen-class calls.
+- Never hardcode a shorter timeout "to fail fast" on this path — failing fast
+  here is what caused the incident.
+
+### 2. Auxiliary tasks — keep template timeouts, one correction
+
+- vision: 60s (keep), web_extract: 30s (keep) — gemma-4-12b averages 2.6s;
+  these are fine.
+- compression: 300s (keep — this was already raised from 60 per gpu-fleet).
+- **gpu-dense delegation/x_search: set timeout >= 120s.** The RTX 3090
+  (qwen3.6-27B-code backend, 23.0s avg) is the same speed class as
+  syslog-auto; delegation defaults that assume fast responses will 408 the
+  same way.
+
+### 3. Retry policy — backoff, not repetition
+
+- On timeout (408) or 5xx: retry up to **2 times** with exponential backoff
+  (**15s, 45s**) before giving up.
+- Do NOT retry in a tight loop. The Sep 6 spike shape (65 failures in one hour
+  from one key) was a batch job retrying without backoff while the backend was
+  down — it multiplied load during recovery.
+- On 401/403: do NOT retry — that is a key/permission problem (see
+  litellm-api-keys.prose.md and Rule 11); retrying just spams the log.
+- On 429: honor the retry-after header if present, else back off 60s.
+
+### 4. Health probes — identify yourself and time out sanely
+
+- Probes MUST NOT appear as keyless, model-less failures in the metrics (12
+  such orphans appeared in the incident window and cost investigation time).
+  Send a real model name and use a real (probe-designated) key.
+- Probe timeout: 30s. A probe that takes longer than 30s IS the alert —
+  report "backend slow (>30s)" rather than hanging.
+- Probe cadence: at most hourly. The 6h litellm-health cron cadence is the
+  standard; sub-hourly synthetic traffic distorts latency baselines.
+
+### 5. Batch/benchmark jobs — schedule away from 04:00-07:00 EDT and chunk
+
+- The incident window showed bulk clients amplifying a backend stall 5:1.
+- Batch jobs that can tolerate delay: schedule 09:00-17:00 EDT.
+- Any batch loop over N requests MUST sleep >= 5s between requests and honor
+  the retry policy in section 3.
+
+## Returns
+
+- A single standard any agent or script can cite: timeouts >= 300s on the
+  syslog-auto path, >= 120s on gpu-dense delegation, backoff retries (2x,
+  15s/45s), identified probes at 30s/hourly, batch jobs chunked and
+  day-scheduled.
+- Failure signature recognition: bulk 408s from multiple keys in one window =
+  backend event (check gpu_utilization_percent: 0% = wedged, ~100% = saturated);
+  single-key 408s = that client's timeout is too short.
+- Cross-references: hermes-config-template.prose.md (Rule 5 nginx 600s,
+  auxiliary timeouts), gpu-fleet.prose.md (compression 300s precedent,
+  stable aliases), litellm-api-keys.prose.md (key/permission failures).
+
+## Intentionally NOT changed
+
+- No server-side LiteLLM timeout/cooldown changes proposed — the incident
+  self-recovered and the server is healthy (0.56s live probe); changing
+  server behavior without process-level root cause (CT116 requires root;
+  not reachable from kagentz) would be guessing.
+- No change to the template's vision/web_extract/compression timeouts —
+  measured data says they are correct.
+- No per-agent key permission changes — those are litellm-api-keys.prose.md
+  territory (and the open gpu-vision/gemma 403 items are already filed with
+  the key owners).
+- No model routing changes — syslog-auto's weighted pool behaved correctly
+  throughout the incident.
