Code Fixes

Verify repair decisions against constrained, reviewable choices. These examples score patch and regression-test ids instead of executing model-written code.

Files

• basic.py — chooses the smallest safe fix for subtle production bugs.
• patch_selection.py — distinguishes patches whose hidden concurrency or protocol behavior differs.
• regression_tests.py — selects the minimal tests needed to lock in a fix.

When to use

Use this pattern when a task can be expressed as a bounded repair decision and checked deterministically. Keep untrusted generated code out of the cookbook process; execute code only inside a separately designed sandbox.

This follows the SQL verification examples in _22_sql_generation/. Continue to _24_structured_extraction/ for typed evidence reconciliation.
