- upgrade-test.py --restep <verdict> --definition <dir> --catalog <c> --evidence <rel>: the only way a
superseded step's own files (steps/<key>.yml + .felhom.yml) change after the fact (Part D: immich's
step 0b8272068aab36bf still pins 512M). Refuses a non-proven or OOM-killing re-proof, the head entry,
and a definition whose images are not the step's; leaves the ladder entry untouched (digests, box
evidence, the box's failed-step fingerprint). Two tests; the gate accepts the result.
- zipline's verify waited on `/` for 200/302/307; on 9202 it answers 301 and the readback returned
False with no line — it now waits on /api/healthcheck like its seed.

update_ladder: in .felhom.yml, one JSON entry per line (spiked live on
controller v0.266.0 and v0.267.0 first). Two gates: check-test-record.py
(static, CI too) and check-test-record-move.py (history + registry for
moved refs only). 16 decoys, 3 red-proofs. The ONLY writer is
upgrade-test.py --write-ladder (bench AND box proven, digests resolved).
Harness v3: box fixtures on the bench, files_may_change.
Backfill: the 21 moves of 2026-09-22, 21 proven from their records.
No image: line moved.
