Module geometry 

The MEASURE contract a painter (built in or a host’s override) must keep for a control (VAPP-92; mirrors src/geometry.ts): its box comes from the theme’s tokens through the recipe of the part that IS the control, never from the painter. control-geometry.json records every built-in theme × control × size; check_geometry is what the conformance suite runs an override through.

Structs

GeometryCase

One fixture case an override is run through.

GeometryFailure

GeometryIssue

MeasuredBox

What a painter reports after measuring the control it drew.

Constants

CONTROL_PARTS

The part whose recipe sizes each control.

DEFAULT_TOLERANCE

The tolerance the TS defaults to.

GEOMETRY_KEYS

Traits

PainterOverride

A host’s replacement painter for one native kind: it may draw anything, but measure must return the theme’s box.

Functions

check_geometry

Every geometry key the theme fixes that the measured box misses or changes (a key the theme leaves open is the painter’s).

control_geometry

The numeric box of a control for a theme (mode-independent), in GEOMETRY_KEYS order, numeric values only.

control_part

The sizing part of a control (root for anything not listed).

verify_painter_geometry

Run an override through every case the fixture holds for its kind; only the failing cases come back (named k=v,… or default).
