 ## Error Handling
 
-- If ALL patches fail: create a draft PR listing every failure with analysis.
-- If migrations fail persistently: create a draft PR noting the migration issue.
-- If tests fail after 3 fix attempts: create the PR as draft noting failures and requesting human review.
-- Always create a PR (even as draft) so work is not lost.
+- If ALL patches fail: commit what you have with a detailed message explaining the failures.
+- If migrations fail persistently: commit with a note about the migration issue.
+- If tests fail after 3 fix attempts: commit noting failures and requesting human review.
+- Always commit and push so work is not lost. The pipeline will create a draft PR.
