- Introduce item-level identifiers/remapping and move graph metadata to registered layers for history, locks, deferred state, parametric data, and supplemental topology. - Replace the old reverse-index/cache/history helpers with storage-owned relations, version stamps, cache registry services, and copy/compact remapping paths. - Preserve layer data, product occurrence refs, persistent mesh handles, deleted history, lock propagation, and topology supplement attachments across copy, compact, transform, reconstruct, and mutation flows. - Update BRepGraph populate/reconstruct/editor traversal and add/refresh GTests for layers, cache services, copy, transform, compact, sparse models, IDs, and storage behavior.
