Phase 1 of the #314/#313 plan (docs/plan-313-314.md): commit a deterministic
full-public-API-surface snapshot as the regression net BEFORE the #313
UIEntity::grid -> GridData refactor, so that refactor reduces to a reviewable diff.
tests/unit/api_surface_snapshot_test.py enumerates the complete public mcrfpy
surface (exported types' methods/properties with docstring-derived type + ro/rw,
12 enums with int values, module functions, singletons, the automation submodule)
and diffs it against tests/snapshots/api_surface.golden.txt. Re-baseline with
MCRF_UPDATE_API_SNAPSHOT=1.
Key design points (verified against source + live introspection):
- mcrfpy.Grid IS mcrfpy.GridView and delegates its real API to an internal
_GridData via tp_getattro -- invisible to dir(). The test walks grid.grid_data
AND probes delegation integrity on a live instance (69/69 members resolve).
- Behavioral writability probes compensate for docstring-derived ro/rw inference.
- Every exported class is classified FROZEN vs EXPERIMENTAL; the snapshot captures
the classification so future additions force a deliberate freeze decision.
Freeze decisions recorded in docs/api-audit-2026-04.md:
- F3: grid_pos is the canonical cell-position name (matches the constructor kwarg);
cell_pos/cell_x/cell_y documented as aliases. Docstrings aligned in UIEntity.cpp.
- F12: deprecated set_scale KEPT in the 1.0 surface (removal would be a new break).
- automation camelCase EXEMPT from the snake_case rule.
- EXPERIMENTAL (exempt): 3D/Voxel, Tiled/LDtk import, Shader, binding helpers.
- FROZEN: core UI/Grid/Entity/value types, enums, procgen (BSP/HeightMap/
NoiseSource/DijkstraMap/AStarPath), Drawable (root).
Doc/stub regeneration and the entity.texture addition are deferred to Phase 2
(the #313 refactor). Addresses #314.

Review of session 1b14b941 found two issues:
- Exported type count was 44 in audit doc but array has 46 entries
(EntityCollection3DIterType and one other were not counted)
- No regression test existed for the Color.__eq__/__ne__ fix
