The d5 Ioniq 6 logs repeatedly reset source tracking when Card repeats a command that already arrived on time. Discard only a recent unchanged repeat after the existing native CAN verifier succeeds; add no sample, application time or permission. Use independently admitted pending CarState brackets to complete original poses without waiting for that command to reach Card. Classify stale control source clocks as transient stale evidence, preserving the original bounded study deadline. Replace Python character loops with equivalent strict text predicates. Validation: focused regression suite and paced d5 replay with original Card command references; actual controller/CAN trial application and worsening-trial rollback. No timing/acceptance threshold changes or claimed road improvement.
