Description

Unit test for whole-component inheritance, see
docs/GRAMMAR/ADR-records/ADR_20261007_GRAMMAR_FIXES.md

Diaphragm.comp is just "DEFINE COMPONENT Diaphragm INHERIT Slit" + END,
so all of its code sections must come from Slit.

One unit of intensity is emitted uniformly from a 1x1 m square:
- a Slit of 0.5x0.5 m passes 1/4:    AfterSlit_I = 0.25
- a Diaphragm of 0.25x0.25 m passes 1/16 of the source: AfterDiaphragm_I = 0.0625

Before the fix, a component inheriting all of its code got none of it, so
the Diaphragm let everything through (AfterDiaphragm_I = 0.25).

Examples

• Test: Detector: AfterSlit_I=0.25
• Test: Detector: AfterDiaphragm_I=0.0625
