prompt: retire smoke-install-stale-jax-pin (shipped, never recorded) + file the drift-detection follow-up

[Jammy2211]

Summary

Mind-state only — no code, no library or workspace change. Two commits.

/start_dev draft/maintenance/ci/smoke_install_stale_jax_pin.md turned out to be a re-pick of already-shipped work. The prompt was resolved as a close-out rather than a build, and the drift that caused the re-pick was filed as its own prompt.

1. 7943d28d — retire smoke-install-stale-jax-pin

The defect the prompt described no longer exists. autolens_workspace_test#266 was opened from this prompt verbatim on 2026-08-23 and closed the same day by PR #268 (a97f052): the jax<0.7 jaxlib<0.7 pin is gone from smoke_install.sh, replaced by the #82 → #184 trail comment and a JAXCHECK assertion on the resolved version. autogalaxy_workspace_test carries the identical fix on main.

All four of the prompt's scope items are covered, the sibling sweep included — an org-wide code search for jaxlib<0.7 now returns no live script, only prompt/record prose in this repo.

The task shipped without touching Mind state: no active.md entry, no active/ move, no completion record. The prompt stayed in draft/ and kept rendering on dashboard.md as pickable backlog with a live /start_dev chip, which is how it came to be picked again on 2026-08-27.

• complete/2026/08/smoke-install-stale-jax-pin.md — new record (header block with issue/PR links and summary; the fix and its two deliberately-not-simplifiable decisions; verification; the sibling sweep; a close-out note on the drift), folding the original prompt.
• draft/maintenance/ci/smoke_install_stale_jax_pin.md — removed.
• complete/index.md — regenerated; the entry carries a hook.
• dashboard.md / dashboard.html — regenerated; backlog 132 → 131, maintenance 20 → 19, chip gone.

2. 845bbefb — file draft/feature/pyautobrain/intake_reconcile_absence_signal.md

Nothing in the workflow detects this drift class, and both candidate guards were checked directly against the restored prompt:

• lifecycle.py check passes. Its invariant is that no active.md slug has a record; a task that skips Mind state entirely is in neither place.
• pyauto-brain intake reconcile reports 0 suspects of 132 scanned — including in --repo autolens_workspace_test mode, pointed straight at the right repo reading its live source at 69ee97c4.

The reason is the shape of the signal. --repo tests presence ("the prompt names things that exist upstream"), and the file this prompt named does still exist. The defect it described was an absence: it quoted the literal pip install "jax<0.7" line, which is gone. A backlog prompt quoting a source line that no longer exists in the file it names is close to a proof the work shipped, and it fires precisely in the no-trace case the current signals are blind to.

Filed as a prompt only; no dev work, and deliberately scoped to detecting the drift rather than to the upstream cause (ship skills not recording Mind state), which deserves its own prompt if it is worth chasing.

Verification

lifecycle.py check and lifecycle.py index --check both OK after each commit. The 0 suspects evidence was produced by restoring the retired prompt into draft/, re-running both reconcile modes, then removing it again — reproduce it that way, not from a fresh backlog.

Note

The autogalaxy_workspace_test companion PR is confirmed landed only by reading its smoke_install.sh on main (the JAXCHECK block is present). Its PR number could not be retrieved — the repo is outside this session's GitHub scope — so the record cites it descriptively rather than by number.

The intake classifier's header for the new prompt was corrected by hand: it resolved target=workspaces / autolens_workspace_test and difficulty=large by keying on the evidence repo the prompt quotes rather than on _intake.py's home in PyAutoBrain — the same failure mode the prompt is about. Both the correction and its reasoning are recorded in the prompt as a Sizing: comment.
