2026-08-23 — abcd site check excludes docs/ at the page walk, rather than teaching the parser to tolerate HTML comments on SSG-authored pages (iss-2608230838592910's own candidate fix, rejected). Tolerating comments would admit mkdocs-material output into gates whose rules were written for generator output — the provenance walk and banned-token gate already exempt the tree via isComposedSurface, so only the mobile and figure-label gates would newly run over markup this repo cannot act on. Those pages never entered the page list on any prior revision either (the parser has always refused comments), so the exclusion removes no coverage that existed; it states the boundary the overflow audit already draws. The cost is recorded honestly in the gate's own scope comment: a green report describes the pages abcd renders and no others, and docs/ layout stays the SSG's own concern.
