Keep the raised overlay footprint as calculation-only geometry for collision, nudge and fit while removing its painted SVG surface and texture. Update Stage 3 contracts, smokes, golden harness rules and synchronized bundles.

Nine of the last ten specs are one class of defect, 23 fix commits in thirty
days, 595 tolerance mentions across ten geometry modules, one every seventh line
in resize.ts. The specs rate their own risk at 9 and 10 of 10, and two titles
show where that arrived: a nearly orthogonal T junction, and a union failure
that must merely damage less.
The ADR names three properties of the data model that produce the stream — a
float coordinate on a 1/240 step, an identity derived instead of stored, and a
wall living in two representations at once — and records four stages against
them. Stage 0 is accepted for implementation; the rest are direction, in the
same sense as #34.
