nx_chartlay_adoption_gate.nx

nx_chartlay_adoption_gate.nx -- datavis DV9 (2026-09-15): THE FLEET RATCHET for the one chart-layout ruler. Names every SVG-emitting function in the compare generators (the sources are DATA in cl_adoption.conf) and refuses a chart that scales, places or colours by hand. An emitter is an ADOPTER when it, or its prefix family (the helpers sharing its name up to the first underscore -- the estate's one-figure-one-prefix convention), calls a ruler verb (the verbs are DATA too); HAND when none does; HAND-COLOUR when the family paints an SVG fill or stroke with a literal rgb() instead of a token. A decorative icon (aria-hidden on the tag) is counted, never judged; an SVG named only in a comment is nothing. Named allow rows exempt one function WITH a reason and can only shrink: an allow row whose function is no longer an offender is STALE and reads RED until deleted, so the ratchet tightens by construction. Planted fixtures prove every class both ways before the live census runs, and the census prints one line per emitter -- a count without a worklist is not actionable. The imprecision lived with: attribute literals are matched in their single-quoted spelling only (the family's emitters use no other), and nx_lineconf_lib is not composed because it is a first-key reader while this file is a ROW LIST with repeated keys. license_tier: ORIGINAL
