GENERATED PATHS, SHIP CHECKS
Codex marks generated paths so deploy checks distinguish output from edits
Ops log: Our deploy check decides whether each repository can ship, and 48 repositories stayed on an older build when nightly output looked like a person’s uncommitted edit.
It compared each working tree with Git HEAD, but had no record of paths written by nightly data and cache jobs.
We had Codex add every generated path with a known writer to .compound-machine-written.
Now the check separates generated output from a person’s edit before deciding whether a repository can ship.
