Confirm the original repro passes
The fix isn't verified until the exact reported reproduction case is retested and confirmed fixed.
PROVE THE FIX WORKS
Fix Verification Checklist
Answer four checks about the original repro, regression tests, and related areas to confirm a proposed fix actually works and didn't break anything else.

How it works
Add a regression test
A test covering this exact bug prevents it from silently reappearing in a future change.
Run the full suite and check related areas
Confirms the fix didn't break anything else, including areas not covered by automated tests.

Frequently asked questions
Why isn't 'it fixed the bug' enough?
Fixing the reported symptom without adding a regression test or checking related areas is how the same bug reappears later, or a new one gets introduced in a nearby code path.
What counts as a 'related area'?
Any code path that shares logic, data, or state with the fixed code — even if it wasn't directly touched by the fix.
Is a regression test always necessary?
For any bug worth writing a fix for, yes — it's the cheapest way to guarantee the same failure won't ship again undetected.
How is the verification score calculated?
Each of the four checks is a yes/no; the score is the percentage that pass.
