Refs #82. Status issued the monitor id (01M5ZQBHEX06T5D50Q96QYKCR6, status#69), committed as 875a18c; test_conf_checks_in_to_status is green. The host steps through the rehearsal are done (#82).

What

• Links: maintaining-host-disk in skills/ and .claude/skills/, the same shape as patching-hosts. docs/SKILLS.md goes from 15 to 16. No submodule bump: a695c02e contains 6a9daba0.
• Host config, tracked: deploy/disk-gc/disk-gc.conf → /etc/cannobserv/disk-gc/disk-gc.conf, installed by hand. scripts/deploy.sh HOST_CONFIGS compares the two. The config:
  • homes = /home/exedev;
  • the template's tiers plus worktrees (worktree_repos = /home/exedev/processor), no docker;
  • the SocratiCode pin kept;
  • lines 85/80.
• pytest: tmp_path_retention_count = 1, tmp_path_retention_policy = "failed". pyproject.toml is runtime, so the merge is a deploy.
• Docs: DEPLOYMENT.md § Disk GC; an AGENTS.md Infrastructure row; the plan, docs/plans/2026-10-27-82-host-disk-gc.md.
• Tests: tests/test_disk_gc.py.
  • The tracked config, parsed with the GC's own parser settings.
  • The pytest knobs.
  • On co-processor only, by hostname: the installed copy matches, and the installed GC's load_config accepts the tracked one. Both fail, not skip, when missing.

State

• Red in this session first: 14 failed before the implementation, all in one commit; there's no separate red commit.
• The CR's 4 fixes are commits CR 1–CR 4. The 5th finding is recorded here: the missing red commit.
• The gate on co-processor: ruff clean. pytest -m 'not integration': 736 passed, 3 failed by design:
  • test_conf_checks_in_to_status fails until the monitor id is committed;
  • test_installed_copy_matches_tracked and test_tracked_conf_passes_the_installed_gc fail until the approved install.
• CI runs off the node, so only the first of the three fails there.

Host steps and approvals: #82.
