Captain ruling 2026-09-10: Mumuni moved off this host onto her own container
(kagentz CT 105 on minipve, 192.168.68.14, dedicated `hermes` user) and is
monitored from her side. This host must not monitor anything Mumuni.
The stale probes fired false alerts repeatedly:
* scripts/zulip-monitor.sh ssh'd to root@192.168.68.24 for the
decommissioned deployment's ~/.hermes/gateway_state.json, read "unknown"
on every run, and posted a 🔴 "Mumuni (Hermes) Zulip state: unknown" DM +
#agent-hub stream alert each cycle.
* scripts/daily-infra-report.py published a matching "mumuni:unknown" row in
every digest.
Changes:
* zulip-monitor.sh: delete the "Platform B: Hermes (Mumuni)" leg and its
notify; keep the Zulip-server, Platform A pi/Abiba (bridge), Platform B
Tanko and Platform C Agent Zero legs. A comment records why the leg is
retired so it is not re-added. Also fixes SC2155 so shellcheck is clean.
* daily-infra-report.py: delete the .24 ~/.hermes/gateway_state.json agent
probe, its hermes --version probe, and the now-dead mumuni render branch.
Abiba (CT 100, its own .24 address) and Tanko legs unchanged; the PVE API
token name is untouched.
* zulip-health.prose.md (v3.1.0): drop the Mumuni-only B4 gateway-process,
B5 heartbeat and B6 response-delivery steps and the stale 192.168.68.24
references; state explicitly that Mumuni is not monitored from this host.
Tanko/Agent-Zero/bridge steps retained.
* agent-health-check.py: correct the v2 changelog roster comment that still
placed mumuni at .24/CT100. No behavior change — the mumuni probe was
already absent from the AGENTS dict; v5 changelog notes the correction.
Tests: tests/test_mumuni_monitor_removal.py pins the removal structurally and
behaviorally — the shipped zulip-monitor.sh is run in a sandbox (only its LOG
constant rewritten) with stub ssh/curl on PATH; the ssh stub records every
target host, so "never reaches .24" and "no Mumuni notify even on the alert
path" are asserted from observed behavior. A mutation check (re-inject the old
leg) fails the suite, so the guarantee is not vacuous.
