"""Per-project codegen-drift regeneration command.

Some projects check in generated artifacts (rendered docs, generated verb/prompt
tables, ...) that drift whenever their source changes. The agent pre-submit
gate (``quality_command``, e.g. ``make gate``) never regenerates them, so drift
only ever surfaces later as CI's own foundation-check-style `git diff
--exit-code` hard-fail — a failure an agent has no way to trace back to its own
task. ``codegen_command`` (e.g. ``make codegen``) is run in the task's
workspace before every push; any resulting drift is committed so the pushed PR
head is never stale. Additive and nullable — null (the default) is a pure
no-op for projects with no generated artifacts, mirroring ``quality_command``.
