Records the first day of worktree-clean.timer on the desktop and rewrites quest/m0/agent-disk-budget.md to what remains. The quest stays open.

Evidence (26 hourly runs, 2026-11-06 08:32 to 2026-11-07 08:10 PST)

  • 53 managed targets reclaimed. No live checkout was reclaimed: 869 "not finished" and 56 "active process" keeps.
  • mbx gc evicted 68.2, 36.0, 0.7 and 18.2 GiB.
  • df / at 08:14 PST on 2026-11-07, with about 20 agents just started: 604G free of 1.9T (68% used). This is the only sample; nothing on the host logs free space.
  • Every run exits 1 on four checkouts: git worktree remove refuses a worktree with submodules (moq/t3-522b4ead), and rev-list exits 128 in the .claude/shared submodule of three moq.pro checkouts. As a result the unit always shows as failed.

Choices made without asking

  • I didn't resume the stale local quest/m0/agent-disk-budget branch. It holds pre-Agent build output can't fill the desktop's disk #7960 work that has already landed. I built on the fresh claim instead.
  • I left the clean.sh fixes to kixelated/dotfiles rather than editing that repo from a moq quest run.
  • The free-space record is a Waiting item that depends on the cleaner logging df /.

Suggested follow-ups

  • kixelated/dotfiles clean.sh: use --force when removing a worktree it has already verified that has submodules; treat a failing submodule rev-list as a keep, not a failure; log df / on each run.

Takeover: merged main (no conflicts), confirmed no clean.sh fix has landed in kixelated/dotfiles, so the quest's Waiting item stands. just check and just ci pass locally.

Automated review by review (OpenAI)

Reviewed 679480e. No actionable findings in this documentation-only change.

The quest remains open, distinguishes the single free-space sample from the required busy-day record, and identifies recurring cleaner failures rather than treating reclaimed space as completion. The proposed handling of an unreadable submodule keeps the checkout, and removal remains conditional on verification. The linked cleaner PR is merged; this PR changes neither cleanup code nor host configuration.

Verification limits: static GitHub review only. The journal counts, host free space, deployment state, and claimed absence of newer cleaner fixes were not independently verified.

ℹ️ Two accuracy gaps in what the quest records; nothing here blocks the doc-only change.

Reviewed changes

  • Goal tightened to "runs cleanly" — a clean run on the desktop is now part of Done, alongside the busy-day free-space record.
  • Journal evidence replaces the install note — 26 hourly runs recorded: 53 managed targets reclaimed, 869 "not finished" and 56 "active process uses" keeps, four mbx gc evictions, and the single df / sample.
  • Recurring failures recorded — every run exits 1 on the same four checkouts, so the unit's red state hides a real failure; both causes and a dotfiles fix are named.
  • New ## Waiting — a busy day after the cleaner logs df /, checked through journalctl.

The wait clears on the first line matching df /, a string clean.sh never prints, and it checks neither a busy day of samples nor the Goal's "runs cleanly" half, so a later run can close this quest with the unit still exiting 1 every hour, or never close it at all. clean.sh already ends with == free space and <N> GB free; ...; the journal has no sample only because set -euo pipefail aborts when clean-worktrees.py exits 1, before that block.

Suggested change

each run; check with `journalctl --user-unit worktree-clean.service | grep -A1 'df /'`
- desktop: a busy day of parallel agents passes after the cleaner logs free space
each run, and the unit exits 0; check the last day with
`journalctl --user-unit worktree-clean.service --since '-1 day'` (`== free space`
lines, with no `failed:` and no closing `clean: some cleanup operations failed`)
and re-read this quest's Goal before deleting it

- `git worktree remove` on `~/worktrees/moq/t3-522b4ead` fails with "working

`--force` after it has verified the checkout, or to deinit submodules first.

The cleaner already passes --force here: retire() in kixelated/dotfiles bin/clean-worktrees.py appends it whenever the worktree index holds a 160000 gitlink, and the comment above it says "Do not deinit: it mutates shared submodule configuration", so this bullet points the follow-up at a flag that is already there and at an option the code rejects. The takeover note checked clean.sh, but that logic lives in clean-worktrees.py.

Suggested change
- `git worktree remove` on `~/worktrees/moq/t3-522b4ead` fails with "working
trees containing submodules cannot be moved or removed". The cleaner needs
`--force` after it has verified the checkout, or to deinit submodules first.
- `git worktree remove` on `~/worktrees/moq/t3-522b4ead` fails with `working
trees containing submodules cannot be moved or removed`, although the cleaner
already passes `--force` here; find why that force is not effective (a stale
installed copy, the gitlink scan, or this git needing it twice)

Walkthrough

The quest document now records results from 26 hourly cleaner runs and four recurring cleanup failures. It updates the planned work to address those failures, log root free space on each run, and collect a busy-day sample. The completion criteria now require a clean desktop run and a PR that records root free space over a busy day.

Merge Risk: Low · up to 67948

The update is mergeable with small documentation corrections: label the utilization percentage and align the journal check with the required sample format.

Full details: Title check

Explanation

The title "quest: record the disk cleaner's first day" matches the main change: the PR records the first day of worktree-clean.timer runs and updates the disk-budget quest file. It is specific and concise, and a teammate scanning history would understand the primary change.

Full details: Description check

Explanation

The PR description states that it records the first day of worktree-clean.timer on the desktop, gives the run evidence (26 hourly runs, reclaimed targets, mbx gc evictions, a df / sample), lists the four recurring cleanup failures, and explains the choices made. This matches the changeset, which updates the quest document with those results and remaining work.

Label the disk utilization percentage.

The placement of 68% suggests that it describes free space. The listed figures instead indicate approximately 32% free and 68% used.

Make the sample format match the check.

If the cleaner logs plain df / output without a label, the check can return no samples. Require a marker on each sample line and make the check match that marker.
