Why: every reference a user makes to a face or edge (fillet and chamfer edges, sketches on faces, shell/draft/offset faces, joints, appearances) is stored as a name and found again after any upstream edit. Those names were re-derived by sampling points of each face and voting, and pieces of a split face were numbered by where their centres lay. After an upstream edit that splits, merges, mirrors or shrinks a face, a fillet or sketch could silently re-attach to the wrong face, and nothing told the user. The kernel now reports exact history for its operations, so names follow it and fail loudly instead of guessing. - crates/doc/src/lineage.rs: a feature's kernel histories composed into one lineage over nameable operands (bodies before the feature, moved copies, shell cavities, tools named by role: sketch curve, cap, box side, imported face). Instrumented: extrude/revolve/sweep/loft tools, join/cut/intersect, lumps after a cut, fillet/chamfer, shell, draft, split face/body, pattern/mirror (bodies and features), combine, boundary fill, move/scale, offset/delete face, thread, import. - crates/doc/src/history_names.rs: names from lineage; split pieces told apart by the faces only they touch (F2:top#[F2:side:l4,F4:side:l4]), merged faces answer to every name (aliases), lump bodies ordered by their faces' names instead of shell order. - crates/doc/src/name_lookup.rs, piece_names.rs: references resolve by exact name, alias or bounding faces, else nearest piece with a warning; names worked out from geometry (operations without history) are reported when only geometry decided. - Format 14: names stored by older formats get a legacy mark and are found as the build that saved them found them (some geometric names name a face history names differently: a tube's outer wall was named after its inner circle). New corpus file saved by 9a979cf. - kernel: Body::lumps carries each piece's history over the whole. - Adversarial tests: split, merge, mirrored twins, shrink to a sliver, moving cut with body pieces, history-less bodies, certified sketch. - docs/book/src/dev/naming.md describes the real mechanism and why.
