Walkthrough

CancelRateTracker::is_over_budget now returns true when the trailing-window cancellation count equals or exceeds the configured budget.

Merge Risk: Moderate · up to b8349

Execution creation now becomes unavailable when cancellations reach the configured budget; add boundary coverage before merging to protect this behavior.

Explanation

The title identifies the Kubernetes cancellation-budget behavior change. It starts with the bracketed lowercase area "[cr-test]" and a lowercase summary, with no trailing period, ticket ID, or internal link.

Full details: Public-Safe Content

Explanation

The pull request diff changes only the comparison in cancel_rate_tracker.rs. The diff contains no credentials, tokens, private keys, internal URLs or hostnames, cloud identifiers, cluster names, workstation paths, production logs, incident details, or undisclosed vulnerability details. The title and description contain no prohibited content.

Full details: Description Follows The Pr Template

Explanation

The description has real content for Summary, Severity and risk, and AI assistance. The Validation section is missing the required validation evidence: “Not run yet” does not name a run and result and does not say “CI on this head.”

Resolution

Replace “Not run yet” under “## Validation” with the validation command or check that was run and its result, or state exactly “CI on this head”.

Full details: Bug Fixes Name A Regression Test

Explanation

The pull request changes application behavior under crates/: is_over_budget now returns true when current_count() equals budget_per_sec. The Validation section only says “Not run yet.” It names no regression test and gives no explanation for missing coverage. Existing over_budget_after_exceeding_limit tests five cancels against a budget of four, so it does not cover the equality boundary.

Resolution

Add a regression test that records exactly the configured budget and asserts is_over_budget() is true. Name that test in the Validation section, or explain there why the test cannot be written.

Test the configured-budget boundary.

The existing tracker test records 5 cancellations for a budget of 4, and the create_execution test records 1 cancellation for a budget of 0. Both remain passing with the old > comparison. Record exactly 4 cancellations in over_budget_after_exceeding_limit and assert is_over_budget(). This protects the Unavailable admission path from accepting a cancellation count equal to the configured budget.

Suggested fix

-fn over_budget_after_exceeding_limit() {
+fn over_budget_at_configured_limit() {
     let t = CancelRateTracker::with_budget(4);
-    for _ in 0..5 {
+    for _ in 0..4 {
         t.record_cancel();
     }
     assert!(t.is_over_budget());
 }
