Compare effective_on values by instant, not raw string.
Validation accepts RFC3339 values with offsets, but data.lib.time.newest sorts effective_on strings lexically. The required-task selectors call this helper, so mixed offsets can select an older task schedule and omit required tasks. Raw equality also allows equivalent instants to bypass duplicate detection.
Reject non-UTC values, or compare parsed nanoseconds in duplicate detection and schedule selection. Add tests for equivalent offsets and mixed-offset ordering.

[low] Missing retirement guard / pattern asymmetry
The deny rule for required_test_tasks_found omits the required_task in latest_required_test_tasks.tasks guard that the analogous required_tasks_found rule uses. The test test_current_required_test_task_remains_denied_until_replacement_is_effective explicitly validates this stricter (fail-closed) behavior, confirming it is intentional. An inline comment explaining the deliberate divergence would help future readers.
Suggested fix: Add an inline comment on the deny rule explaining that the retirement guard is intentionally omitted for test tasks, e.g. # Unlike required_tasks_found, test tasks remain denied until the newer entry becomes current.

Summary
Add opt-in, time-gated required test task enforcement using tasks discovered from the build PipelineRun and trusted ITS PipelineRuns associated with verified test-result statements. Ordinary required build tasks remain build-provenance-only.
