ADR 0607 §3, §5 and design 51 *Tagged versions*: the composition is handed the check's heard tags (CompositionReader.Compose's tagged), so the node-engine member's composer no longer takes the other members' heads where a tag stands. The trunk's manifest validator stays without tags (ADR 0633 clause 6). Claude-Session: https://claude.ai/code/session_01NcbgfFSnn24M3GcqttoU7i
