Subject: [PATCH 1/9] fix(infra-monitoring): move probes to versioned script
 with port-drift test

The 2026-09-17 false-verdict incident (third recurrence) showed that prose
policy is not a control: the agent probed :9325/:9405 (nonexistent ports),
CT 116 for PVE API (should be real PVE nodes), and rendered TLS failures as
connection-refused. This moves the canonical probe set into
scripts/infra-monitoring.sh (executed verbatim by the contract) and adds
scripts/test_infra_monitoring.sh which asserts every probed port matches the
documented value.

- scripts/infra-monitoring.sh: one script per contract pattern; all targets,
  ports, paths, and expected-status rules in code; -k for PVE self-signed
  certs; non-zero exit naming every failed target; no OK summary on failure
- scripts/test_infra_monitoring.sh: 20 assertions covering port drift,
  monitoring-host-as-PVE-node, and missing -k flag
- infrastructure-monitoring.prose.md: check-health section now references the
  script as executable owner; paste its raw output verbatim

Proof: all 13 legs pass (exit 0); deliberately broken Grafana port (9325)
produces 'probe-failed: 192.168.68.116:9325 (expected 200)' and exit 1.

Subject: [PATCH 2/9] docs(disk-gc): clarify GC schedule applies to PBS
 datastore only

The 20:00 UTC PBS GC cron (proxmox-backup-manager datastore prune)
applies only to /tank/pbs-backup (pbs-datastore). It does NOT touch
media volumes (/media/*) which are report-only at all threat levels.

This clarification prevents the recurring confusion where a 96% media
volume triggers a GC expectation, when the GC schedule never applies
to it.

Closes the 2026-09-17 correction: 'the GC schedule is now 20:00 UTC,
protects the backup datastore, NOT the nearly-full media volume.'

+## GC SCHEDULE (PBS datastore only)
+
+The PBS GC schedule `0 20 * * *` (20:00 UTC) applies **only** to the PBS datastore
+(`/tank/pbs-backup` on storepve), NOT to media volumes. Media volumes (/media/*) are
+report-only at all threat levels. The cron job runs `proxmox-backup-manager datastore
+prune --datastore storepve-datastore --keep-daily 35` which only affects the PBS
+datastore; it does not touch media volumes or any other filesystem.

 escalation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

HOST-RED on media volumes says 'capacity decision — owner to decide' not
'immediate owner attention'. Media volumes are report-only at all levels; the
urgency language was misleading. PBS datastore and host-root get the immediate
attention wording.

Closes the welcome-back proposal: 'how the disk-gc check should classify a
media volume so HOST-RED stops meaning nothing.'

Subject: [PATCH 4/9] fix(infra-monitoring): resolve PR #115 review findings
 (A1-A3, B1-B2, C1-C2)

A1: Test -k assertion now checks use_k:+-k syntax (actual bash pattern)
A2: PVE_NODES assertions now count expected nodes and verify exact array size
A3: Test now asserts liveness behavior (PVE_API_LIVENESS=1) not source text
B1: disk-gc GC schedule corrected: cron runs pbs-gc.sh (not proxmox-backup-manager),
    schedule is 20:00 LOCAL (00:00 UTC, not 20:00 UTC), host timezone America/New_York
B2: PROBE SHAPE now documents actual output shape including TLS flag notes
C1: TLS kind is now printed in PVE API failure output
C2: SSH retry logic clarified - retry is in probe_http function (not unreachable)

 ## GC SCHEDULE (PBS datastore only)
 
-The PBS GC schedule `0 20 * * *` (20:00 UTC) applies **only** to the PBS datastore
-(`/tank/pbs-backup` on storepve), NOT to media volumes. Media volumes (/media/*) are
-report-only at all threat levels. The cron job runs `proxmox-backup-manager datastore
-prune --datastore storepve-datastore --keep-daily 35` which only affects the PBS
-datastore; it does not touch media volumes or any other filesystem.
+The PBS GC schedule is defined in ONE authoritative place: `/etc/cron.d/pbs-gc` on storepve.
+The schedule is `0 20 * * *` (20:00 LOCAL = 00:00 UTC, since host timezone is America/New_York).
+This applies **only** to the PBS datastore (`/tank/pbs-backup`), NOT to media volumes.
+Media volumes (/media/*) are report-only at all threat levels.
+
+The cron runs `/usr/local/bin/pbs-gc.sh` which executes:
+```bash
+proxmox-backup-manager garbage-collection start storepve-datastore
+```
+This is NOT a `prune` operation; it is a GC pass that reclaims unreferenced chunks.
+There is no `--keep-daily` flag; retention is governed by jobs.cfg (keep-daily=35).
+The GC does not touch media volumes or any other filesystem.

Subject: [PATCH 5/9] fix(test): stub curl/ssh to assert actual call targets
 (A2+A3)

Rewrote test to run the monitor with stubbed curl/ssh on PATH that
capture the exact argv of each probe call. The test now asserts the
URL+port of every leg actually requested, not source text or config
constants.

A2: PVE node assertions now check the exact URL in the curl log
    (https://192.168.68.9:8006/... must appear), so a wrong IP
    (e.g. .99) fails the test.

A3: Grafana/Prometheus/LiteLLM assertions check the URL the call
    actually builds, so a hardcoded wrong port in the CALL (while the
    config variable stays correct) fails the test.

Mutation evidence:
  A2: sed s/192.168.68.9/192.168.68.99/ in PVE_NODES -> suite FAILS
  A3: sed s/"$GRAFANA_PORT"/"9999"/ in probe call -> suite FAILS

Results: 18 passed, 0 failed (baseline); 17/18 on each mutation

Subject: [PATCH 6/9] fix(zulip-health): skip server leg when credential is
 placeholder
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When ZULIP_API_KEY is unset or contains 'placeholder'/'REDACTED', skip
the global Zulip server leg with a ⏭ marker instead of failing the whole
script. The pi/Tanko/kagentz legs do not need the Zulip API key and keep
their verdicts.

Tracked as: zulip-health-credential-placeholder-20260913 (captain-held)

This removes the repeated 'Action required' noise every cycle while
keeping the credential enforcement loud and visible.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

F1: Make kind classification real — append (<kind>) to every failure
     line, assign kind=tls on curl exit 35/60, fix :112 where
     kind=refused was set on successful retry. Update prose shape.
F3: Move credential placeholder skip from server probe to notify()
     only — server is always probed (200 without auth verified live).
F4: notify() logs ALERT SUPPRESSED when credential unusable so
     alerts from other legs are not silently dropped.
F7: Restore trailing newline in infra-monitoring.sh.

F5 (DO NOT CHANGE): Verified directly — ssh root@192.168.68.6
     'grep -n keep-daily /etc/pve/jobs.cfg' returns five
     prune-backups keep-daily=35 lines. Prose is CORRECT.

Test: 18 passed, 0 failed (bash scripts/test_infra_monitoring.sh)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

F1: Set LAST_KIND on unexpected-status path (was unset, causing empty
     placeholder in 7 failure lines).
F2: Implement TLS detection — capture curl exit code and map TLS
     error codes (35|51|58|59|60|77|83) to kind=tls. Previously
     TLS failures were misdiagnosed as timeout.
F3: Header comment now lists all producible kinds:
     timeout | refused | tls | unexpected:<code>.
F4: Add 2 test assertions: Grafana failure line exists + kind
     is non-empty (proves the gap that shipped in round 2).

Test: 20 passed / 0 failed (bash scripts/test_infra_monitoring.sh)

From 933cfd223b54c07cc4e34d9464a7d698469b3783 Mon Sep 17 00:00:00 2001
From: root <root@abiba.dns.sysloggh.net>

Subject: [PATCH 9/9] =?UTF-8?q?fix(infra):=20PR=20#115=20round=204=20?=
 =?UTF-8?q?=E2=80=94=20fix=20TLS=20detection=20+=20remove=20duplicate=20pr?=
 =?UTF-8?q?obe?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Round 3 had:
1. rc captured from wrong command (tr always exits 0)
2. Every probe issued TWICE (26 invocations instead of 13)
3. TLS branch unreachable

Round 4 fixes:
- Restructure probe_http to ONE invocation that captures both output
  and status: out=$(...); rc=$?
- Delete the duplicated block
- Fix retry classification: don't overwrite kind if already set (e.g., tls)
- Add test 7b: TLS error (000 + exit 60) → kind is tls
- Update header output shape to include (<kind>) suffix

Test: 22 passed / 0 failed (bash scripts/test_infra_monitoring.sh)
