Independent, self-initiated QA and verification samples tied to public code changes. These reports are portfolio work, not client commissions.

Report Scope Primary evidence Account normalization verification JavaScript behavior, regression tests, CI attribution 12 passing tests plus an independent mixed-input reproduction SDK limit-query re-test Regression re-test, edge cases, mergeability 16 passing tests, five direct API cases, and a conflict check

Define the changed behavior and the closest failure mode.

Check diff scope and whitespace before running the focused suite.

Reproduce the behavior independently with representative edge cases.

Separate failures caused by the change from repository-wide baseline issues.

Record the exact command, result, revision, and remaining blocker.

Re-test fixes and update the verdict instead of repeating the original claim.

expected versus observed behavior;

severity and user impact;

focused regression matrix;

screenshots or logs when they add evidence;

prioritized product observations separated from confirmed defects.
