Candidate Universal Shell amendment surfaced from Cycle 5 retrospective: candidate-queue-status is not enforcement. The Breakdown-Detection Mechanism amendment (07342af4) was ratified into the candidate queue but the orchestrator continued making the same family of breakdowns (8 instances this session) it was designed to prevent. Pattern argues for an accelerated promotion path for candidate amendments that observably prevent ongoing breakdowns — distinct from the standard meta-cycle promotion queue. Rule shape proposal: when N>=3 friction events occur within a single cycle that would have been prevented by a candidate-queue amendment, that amendment auto-flags for accelerated promotion review.
