"""steps_backfill.py — ONE-OFF (2026-09-24, `09` §6.4 part 5): write `steps/<step_key(to)>.yml` for every
|
|
ladder entry that is not the newest, from git history.
|
|
|
|
WHICH COMMIT, and why not "the commit of the step": the definition a box must pin for a step is the one
|
|
the catalog SERVED while that step was the head — the NEWEST commit whose compose images equal the
|
|
step's `to`, i.e. the step's images WITH every fix that flowed after they moved. The commit that MOVED
|
|
the image can be the broken one: romm's 15f9ebf (5.0.0 -> 5.3.0, 512M, four workers) OOM-looped on
|
|
demo-hp; the working definition is the same images under f4eb94f's template (768M, two workers).
|
|
|
|
Prints one line per step: app, entry, step key, the commit it came from. Never overwrites a step file.
