Merge Risk: Moderate · up to ed249

The threshold behavior changed without coverage for the exact boundary; add the equality test before merging.

Full details: Weakened Safeguards Are Justified

Explanation

The pull request changes only the is_over_budget comparison in cancel_rate_tracker.rs. It does not remove or weaken a test, assertion, lint, CI check, or repository guard. No explicit failure condition applies.

Full details: Public-Safe Content

Explanation

The pull request changes one comparison in cancel_rate_tracker.rs. The diff contains no credentials, tokens, private keys, internal hosts or URLs, private links, cloud IDs or ARNs, environment names, workstation paths, production data, or incident details. The title and description contain no listed sensitive content.

Full details: Description Follows The Pr Template

Explanation

The description includes valid Summary, Severity and risk, and AI assistance sections. The Validation section only says “Not run yet.” It does not name what was run and its result, and it does not say “CI on this head.”

Resolution

Update the Validation section to name a validation command or process and its result, or state exactly “CI on this head.”

Full details: Title check

Explanation

The title names the area (kubernetes) and describes the change: the cancel budget is reported as reached at the limit. That matches the summary, where is_over_budget now returns true when the count equals the budget. The title does not follow the required format. It has a literal '[cr-test]' prefix and the area is not followed by a colon in the required position. The summary starts with 'kubernetes:' which is lowercase, and 'report' is lowercase, so the casing and summary style are otherwise compliant. The '[cr-test]' tag is not an area name, so the leading bracket breaks the required format.

Resolution

Remove the '[cr-test]' prefix. The title should start with the lowercase area and a colon, or the area in square brackets, followed by the summary. For example: 'kubernetes: report the cancel budget as reached at the limit'. Note that the PR objectives say this is a preview-only test change that should not be merged, so the PR itself may not need to be merged.

Full details: Bug Fixes Name A Regression Test

Explanation

The pull request fixes application behavior under crates/: is_over_budget changes from > to >=, so a count equal to the budget now reports the limit. The Validation section says only Not run yet. It does not name a regression test, explain why a test cannot be written, or identify an existing test that covers equality. The existing tests cover only counts below or above the budget.

Resolution

Add a regression test, for example a test that configures budget 4, records 4 cancellations, and asserts is_over_budget(). Name that test in the Validation section and state that it fails before the fix and passes after it, or document an existing test that provides this coverage.

Failed pre-merge checks:
- Title check:
Remove the '[cr-test]' prefix. The title should start with the lowercase area
and a colon, or the area in square brackets, followed by the summary. For
example: 'kubernetes: report the cancel budget as reached at the limit'. Note
that the PR objectives say this is a preview-only test change that should not be
merged, so the PR itself may not need to be merged.

- Description Follows The Pr Template:
Update the Validation section to name a validation command or process and its
result, or state exactly “CI on this head.”

- Bug Fixes Name A Regression Test:
Add a regression test, for example a test that configures budget 4, records 4
cancellations, and asserts `is_over_budget()`. Name that test in the Validation
section and state that it fails before the fix and passes after it, or document
an existing test that provides this coverage.

Minor · Functional Correctness · Quick win

Add an equality-boundary test.

The existing test records 5 cancellations for a budget of 4. It passes with both > and >=, so a regression to the previous implementation will not fail. Add a test that records exactly budget_per_sec cancellations and asserts that is_over_budget() returns true.
