Function run_post_commit 

pub fn run_post_commit(
    request: &PostCommitRequest<'_>,
    git: &PushGit,
    err: &mut dyn Write,
) -> Result<PostCommitOutcome, SingleFlightError>

What: Run the gate, print its events, and back up the landed commit only when the gate allows it. Why: The incumbent prints the events before the backup and never backs up a blocked commit; a failed backup is reported by auto_push and never changes the outcome’s exit code.

In TS you’d write (pseudocode):

const result = await runPostCommitLifecycle(input);
process.stderr.write(renderPolicyEvents(result.events));
if (!result.blocked) await autoPush({ gitPath, cwd, landedOid: result.oid });
