Unique opening match gate

The W207 4/11 and adjacent 4/12 marks remain verified printed readings, but the earlier assignment of 4/11 to elevation B02 is retracted. W-6 independently prints 4/11 on the Broadway/page-right strip near Madison/south; its north arrow points page-bottom. The W-6 position conflicts with B02 near Main/north. B09 is only a nearby station candidate, not an accepted identity.

Physical geometry authorization

Direct transcription of the remaining Broadway fourth-floor historic marks after 4/12; Formal printed legend sentence defining the split-circle syntax; Accepted equivalence between W207 masonry/jamb limits and the IMG_1231 traced visible-envelope boundary; Exact wall-face X and physical opening depth; Accepted rough, masonry, frame and clear opening boundary classifications; Accepted W207 Section C-C return-depth assignment to a verified opening; Independent surveyed station for the W207 4/11 instance; Opening frame profile, sill, head, anchors and construction interfaces; Whole-sheet review of all W207/W208 notes, material codes, revisions and callouts

Transfer of the separate B05 diagnostic geometry to the W207 target

The B05 horizontal-placement packet is a separate diagnostic built before the W207 split circle was decoded. Its provisional station, traced envelope and candidate wall host do not describe the W207 4/11 instance and must not be copied to B02.
