- package.json out of the trigger paths: the tag hash deliberately excludes it (version bumps every ship), so every merge rebuilt and re-pushed the IDENTICAL tag (~2m26s for zero content change); patches/** added (it IS a tag input) - manifest existence check (mirrors evals.yml): tag already exists → skip the build - concurrency group: two rapid main pushes raced pushing the same :latest/:buildcache tags - cron staggered 06:00→04:00 Monday: it shared the exact minute with evals-periodic, which could race a half-pushed tag or duplicate the build - timeout-minutes: 30 (was unbounded → 360-min default for a hung docker build) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
