-**B1: Gateway State**
+### Step 3: Platform B — Tanko (DSH on amdpve CT 112) & Mumuni (Hermes)
+
+Tanko runs on DSH (DeepSeek Harness) — it no longer runs a Hermes gateway, so
+there is no `~/.hermes/gateway_state.json` on CT 112. Tanko's Zulip gateway runs
+as the `dsh-web` systemd unit inside **CT 112**, which resides on the **amdpve**
+PVE host (**192.168.68.15**). Direct SSH to 192.168.68.122 is not a dependency
+of this contract — per-worker key availability varies — so CT 112 probes run
+from the amdpve vantage via `pct exec`:
 
 ```bash
+ssh root@192.168.68.15 "pct exec 112 -- <command>"
 ```
 
-Tanko runs on DSH (DeepSeek Harness) — it no longer runs a Hermes gateway, so there is no `~/.hermes/gateway_state.json` on CT 112 (.122). Verify Tanko's Zulip connectivity via the DSH harness bot status instead.
+> **By design (verified 2026-09-08):** the `dsh-web` gateway binds
+> `127.0.0.1:3080` **loopback-only**. A remote probe against
+> `192.168.68.122:3080` gets connection-refused — that is EXPECTED, NOT a fault,
+> and must never be raised as Tanko down. Only loopback probes from inside
+> CT 112 (or the public-URL fallback below) are valid health signals.
 
-Check `platforms.zulip.state`: `connected` ✅ | `disconnected` ❌ | `error` ❌ | missing → not installed.
+**B1: Gateway Service State (Tanko)**
 
-**B2: Agent Process**
+```bash
+ssh root@192.168.68.15 "pct exec 112 -- systemctl is-active dsh-web"
+```
+
+Expected: `active`. Anything else → gateway service down → apply the Tanko heal
+(restart via DSH service, Platform B Actions table below).
+
+**B2: Gateway HTTP Liveness (Tanko — loopback-only :3080)**
+
+```bash
+ssh root@192.168.68.15 "pct exec 112 -- curl -s --connect-timeout 5 --max-time 10 -o /dev/null -w '%{http_code}' http://127.0.0.1:3080/"
+```
+
+Alive = **ANY** HTTP status response from the endpoint — the expected set is
+`200`/`301`/`302`/`307`/`308`/`401`/`403` (the gateway UI is token-gated and
+legitimately answers with redirects/auth-challenges, so never require a bare
+`200`), and any other status, including `404`/`5xx`, also counts alive: a
+process answering `503` is running and self-heal must NOT restart-loop it.
+Down = connection refused (`000`) or timeout only. Statuses outside the
+expected set are logged/reported as a warning — reported, never healed on.
+
+**B3: Public-URL Fallback Probe (Tanko — for nodes without pct/ssh access to amdpve)**
+
+```bash
+curl -s --connect-timeout 10 --max-time 15 -o /dev/null -w '%{http_code}' https://tankodhs.sysloggh.net/
+```
+
+Fallback only — used when the monitoring node has no pct/SSH path to amdpve.
+Alive = **ANY** HTTP status response from the endpoint — healthy signals are
+`302` (authentik proxy-auth redirect) and `401` (auth-gated), and any other
+status, including `404`/`5xx`, also counts alive: the endpoint is up and
+answering and must NOT be restart-looped. Down = connection refused (`000`) or
+timeout only. Never expect a bare `200` — the public URL terminates in the
+token-gated authentik chain. Statuses outside the healthy set are
+logged/reported as a warning — reported, never healed on.
+
+**B4: Gateway Process** (Hermes agent Mumuni only — Tanko runs no Hermes gateway)
 
 ```bash
 ssh root@<CT> "ps aux | grep 'gateway run' | grep -v grep"
 ```
 
-Gateway PID should exist with uptime > 60s. **Dual-gateway detection**: if more than one `gateway run` process is found, the gateway has a collision (typically one `--force` and one `--replace` process). Kill the newer/duplicate process, then restart the remaining gateway per-agent (parameterized 2026-08-09, captain ruling):
