The fieldtest's spec_gap closed per the #316 decision (tighten, not ratify): doc_gate normalizes the doc against both the full entry name and its bare display segment after the last :: -- an extension node ns::Scale with doc "Scale" now refuses (RestatesName), matching the register seam's effective bare-name behaviour. Unnamespaced entries are unchanged (the checks coincide); genuine meaning lines containing the name as a substring stay accepted (equality, not containment). The C29 contract sentence carries the precision. Gates: workspace green (98 suites, 0 failed -- incl. the C29 coverage walk over every shipped doc under the tightened gate), clippy clean. refs #316
