 - 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)`

+**All six verdict shapes** (exactly as emitted by the script):

+1. **Healthy** (fresh GC, 0 B pending):
+   `✅ PBS GC: healthy (last run 1h ago, pending-bytes: 0 B)`
+
+2. **Stale** (GC ran >48h ago):
+   `🔴 PBS GC: stale (last run 49h ago, pending-bytes: 1048576 B)`

+3. **Probe-failed: empty read** (000/timeout/unreadable):
+   `🔴 PBS GC: probe-failed: storepve:192.168.68.6 (expected JSON, got 000)`

+   `🔴 PBS GC: probe-failed: storepve:192.168.68.6 (unparseable JSON)`
+
+5. **Never-run: datastore absent** (valid JSON but storepve-datastore not in list):
+   `🔴 PBS GC: never-run (storepve-datastore not found in GC list)`
+
+6. **Never-run: no endtime** (valid JSON with datastore present but last-run-endtime is null/0):
+   `🔴 PBS GC: never-run (storepve-datastore has no last-run-endtime)`
