+- **2026-09-24 (morning) — STEP DEFINITIONS (`5ed599c`).** Every ladder entry but the newest has its own compose at
+  `templates/<app>/steps/<ladder.step_key(to)>.yml` (sha256 of `to`, canonical JSON, 16 hex = controller
+  `stacks.StepKey`); gate rule 4 + decoys; the writer keeps the superseded step; 8 backfilled
+  (`steps_backfill.py`, one-off, from the NEWEST commit naming the step's images). Controller v0.268.0 reads them:
+  one press = one step (proven live, romm two steps). R-653/R-656 fixed in the bench; the two suites that typed
+  live pins now read them (R-663). Open: R-652, R-655, R-664 (a step has no `.felhom.yml` of its own).
 - **2026-09-24 (night 2026-09-23) — THE TEST RECORD.** An `image:` move needs a proven `update_ladder:` entry
   (`scripts/ladder.py`; gates `check-test-record.py` + `check-test-record-move.py`; the only writer
   `upgrade-test.py --write-ladder`). 21 older moves backfilled; 12 steps published tonight. Harness v3: box fixtures
