The tail-header cap fix pushed SearchBlock's head/tail slicing arithmetic and its copy-feedback hook over the duplication gate's threshold against the byte-identical logic in TerminalBlock. Extract both into head-tail-cap.ts (headTailCap) and use-copy-feedback.ts (useCopyFeedback) and consume them from both blocks, deleting the clone rather than nudging it under the limit.
