# Receipt

> You fixed it? Show me the receipt.

Reuse supplied guidance; discover missing instructions only within authorized roots, never through an out-of-scope ancestor sweep. Report inaccessible evidence instead of broadening access.

For a current bug, select a regression on the actual affected path using the documented runner. Reuse valid before evidence; otherwise observe the defect-specific failure, implement the requested fix, then rerun unchanged assertions/inputs. Preserve neighboring behavior and required coverage. Inspect history only for unresolved behavior or implementation.

For an already-present fix, committed or not, requiring historical comparison, use the [isolated comparison procedure](references/existing-fix.md). Don't reverse patches in the user's working tree.

A required suite running that regression with matching inputs/runtime supplies after evidence; don't repeat it separately. Skipped, undiscovered or differently configured tests don't qualify. Changed relevant inputs invalidate reused results.

Batch final checks in one shell call, adapting the runner and paths:
