Subject: [PATCH 1/4] feat(proxmox): Add PBS GC liveness signal

Add monitoring leg that checks storepve-datastore GC health:
- Reads GC state from CT 107 via pct exec
- FAILS if last-run-endtime is older than 48h
- Reports age in hours and pending-bytes status
- Uses JSON parsing for reliable data extraction

Test: All 5 legs OK, Exit 0.

Subject: [PATCH 2/4] docs(proxmox): Add PBS GC documentation to
 proxmox-monitor.prose.md

Document the PBS GC schedule (00:00 UTC, not 20:00 UTC as PR #116 said),
what actually runs (pbs-gc.sh -> pct exec 107 -- proxmox-backup-manager),
datastore location (CT 107's /mnt/pbs-backup on /tank/pbs-backup, NOT
/media/easystore2), and the new liveness check (48h threshold, reports
age in hours, explicit healthy line).

+## PBS GC (Proxmox Backup Server)
+
+### Schedule
+Cron `0 20 * * *` on the **storepve HOST** (192.168.68.6) = 20:00 America/New_York local = **00:00 UTC**.
+
+**NOTE**: The closed PR #116 said "20:00 UTC" — this is WRONG by four hours. Do not copy it.
+
+### What Actually Runs
+Host script `/usr/local/bin/pbs-gc.sh` runs `pct exec 107 -- proxmox-backup-manager garbage-collection start storepve-datastore`.
+
+**IMPORTANT**: The tool `proxmox-backup-manager` exists only inside CT 107 (where the PBS server runs). The storepve host has only `proxmox-backup-client`. This is why the job had never worked before 2026-09-19 00:00 UTC.
+
+### Datastore Location
+- **Datastore**: CT 107's `/mnt/pbs-backup` on the storepve ZFS dataset `/tank/pbs-backup` (pool `tank`, ~11T free)
+- **NOT** `/media/easystore2` (media library, 3.7T, 96% used — separate volume)
+
+### Liveness Check
+The new `proxmox-monitor.sh` leg checks storepve-datastore GC health:
+- Reads GC state from CT 107: `pct exec 107 -- proxmox-backup-manager garbage-collection list --output-format json`
+- **FAILS** if `last-run-endtime` is older than 48 hours
+- Reports age in hours and pending-bytes
+- A failed probe (000/timeout) is reported as `probe-failed: storepve:192.168.68.6 (expected JSON, got 000)` — **never** rendered as "GC stale"
+- The healthy branch prints an explicit healthy line: `✅ PBS GC: healthy (last run Xh ago)`

Subject: [PATCH 3/4] fix(proxmox): Fix PBS GC liveness leg + add comprehensive
 test suite

(a) Probe-failure detection: now treats empty OR unparseable JSON as
     probe-failed, not never-run. This prevents 'command not found'
     outputs from being rendered as service verdicts.

(b) pending-bytes: now extracted from JSON and reported in stale verdict.

(c) Null endtime: use .get() with explicit None check, not 0 fallback.
     null values now correctly trigger never-run verdict instead of
     arithmetic crash (set -u).

(d) Tests: Added 14-assertion stub-driven suite covering: healthy,
     stale (>48h), probe-failed (empty and unparseable), null endtime,
     datastore absent. Each test stubs ssh/curl to verify exact
     behavior against the pre-fix head.

Subject: [PATCH 4/4] docs(proxmox): Document all six PBS GC verdict shapes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Liveness Check section now documents ALL SIX verdict shapes exactly
as emitted by proxmox-monitor.sh:

1. ✅ PBS GC: healthy (last run Nh ago, pending-bytes: N B)
2. 🔴 PBS GC: stale (last run Nh ago, pending-bytes: N B)
3. 🔴 PBS GC: probe-failed: storepve:192.168.68.6 (expected JSON, got 000)
4. 🔴 PBS GC: probe-failed: storepve:192.168.68.6 (unparseable JSON)
5. 🔴 PBS GC: never-run (storepve-datastore not found in GC list)
6. 🔴 PBS GC: never-run (storepve-datastore has no last-run-endtime)

Fixed the quoted healthy example (line ~114) to include the pending-bytes
suffix the code now appends. Previously the prose only documented the
probe-failed shape, missing the PR's own headline cases (never-run).

Proof: grep -n 'never-run' proxmox-monitor.prose.md now returns two lines
(lines 106 and 108), documenting both never-run variants.
