fix: correct tanko runtime to DSH across contracts & scripts
Tanko migrated from Hermes to DSH (DeepSeek Harness) on 2026-08-27. Update all
records that described tanko as a Hermes agent / Hermes runtime:

- infra-control: CT 112 tanko platform Hermes -> DSH
- zulip-health / zulip-self-heal / zulip-mention-reliability / pi-approval:
  tanko is on DSH, mumuni remains on Hermes
- memory-audit-maintenance: exclude tanko from Hermes roster (uses DSH-native memory)
- hermes-config-template / hermes-agent-baseline: remove tanko from Hermes roster,
  keep LiteLLM key alias 'tanko'
- hermes-zulip-plugin / hermes-zulip-restore / build-zulip-plugin: tanko excluded
- infrastructure-maintenance: gateways check no longer probes Hermes on tanko CT112
- scripts/daily-infra-report.py: fix CT-ID regression (CT 122->112), report tanko as DSH
- scripts/zulip-monitor.sh: stop probing tanko's retired Hermes gateway
- scripts/agent-health-check.py: skip Hermes gateway checks for tanko (runtime=dsh)
- scripts/prose-auth-check.sh + AGENTS.md: authorize tanko/tanko-bot for its own records

Tanko remains CT 112 at 192.168.68.122; infrastructure facts unchanged.
Dated/incident records (run logs, migration logs) left intact as history.

RETIRED 2026-07-04 — Zulip extension decommissioned. Abiba now operates
exclusively through Telegram (@AbibaBot). This contract is kept for
historical reference only.
---
> **⚠️ RETIRED** — The pi Zulip extension (`~/.pi/agent/extensions/zulip/`) and
> PM2 process (`abiba-zulip`) have been decommissioned. All mention/reliability
> monitoring now happens through Telegram. Agents (Mumuni on Hermes, Tanko on DSH) and
> Agent Zero (kagentz) continue to use Zulip.
## Maintains
- mention_response_rate: number — % of @mentions that get a response (target: >95%)
- last_test_result: "pass" | "fail" | "degraded"
- known_failure_modes: array — History of what went wrong and how it was fixed
- queue_health: "healthy" | "expired" | "reconnecting"
**Postconditions**
- test_mention_gets_response == true — Send @Abiba Bot test, confirm response within 30s
- stream_subscription_active == true — Bot is subscribed to #agent-hub and #general chat
- queue_active == true — PM2's event queue is registered and polling
- no_echo_loop == true — Bot doesn't respond to its own messages
- dm_always_works == true — DMs still respond even if streams are broken
## Known Failure Modes (from History)
| Failure | Root Cause | Fix |
|---|---|---|
| No stream events | Bot had 0 stream subscriptions | Subscribe via API |
| No @mention detection | botUserId was null (register endpoint doesn't return it) | Fetch from /api/v1/users/me |
| No stream events | zulip-js library sends multipart/form-data instead of form-urlencoded | Use URLSearchParams directly |
| Double responses | Both TUI and PM2 loaded the extension | ZULIP_EXTENSION_ACTIVE guard |
## Remediation Rules
### Rule 1: Queue Expired
- Detect: Poll returns BAD_EVENT_QUEUE_ID
- Fix: `pm2 restart abiba-zulip`
- Verify: Check logs for "Connected, queue:"
### Rule 2: Subscription Missing
- Detect: `GET /api/v1/users/me/subscriptions` returns 0 for #agent-hub
- Fix: Subscribe via `POST /api/v1/users/me/subscriptions`
- Verify: Re-check subscriptions
### Rule 3: Extension Crashed
- Detect: PM2 status shows "errored" for abiba-zulip
- Fix: `pm2 restart abiba-zulip`
- Escalate: If restarts >5 in last hour, alert user
### Rule 4: No Response to Test Mention
- Detect: Send test @mention, wait 30s, check if response appeared
- Fix: Run diagnostics (check queue, check code, check logs)
- Log: Record failure mode as new entry in Known Failure Modes
## Continuity
- **On user report**: User says "you didn't respond" → run diagnostic
- **On test failure**: Test mention fails → run remediation
- **Retrospective**: Every 6 hours — send a test @mention to self-verify
- **On PM2 restart**: Always run a self-test after restart
## Execution
1. **Self-test**: Send `@**Abiba Bot** _selftest_` in #agent-hub, wait for response
2. **If no response in 30s**: Run diagnostics
3. **Diagnose**: Check queue, subscriptions, PM2 status, logs
4. **Fix**: Apply matching remediation rule
5. **Retest**: Try again
6. **Log**: Record success or new failure mode
7. **Report**: DM user only if escalation needed
