UIEntity now depends on the grid DATA layer only:
- GridData gains cell_width_px/cell_height_px (mirrored from the grid
texture in UIGrid's 5-arg ctor; texture is write-once) so entity
tile<->pixel math no longer reaches into rendering (getTexture()).
- GridData gains markDirty()/markCompositeDirty(): set the flag on the
UIGrid subobject AND notify owning_view, covering both render paths.
UIGrid disambiguates via 'using UIDrawable::markDirty' so all
pre-existing UIGrid-receiver calls resolve exactly as before.
- The three Python wrappers that still need the full UIGrid (GridPoint
from entity.at(), the _GridData fallback in get_grid, find_path's temp
wrapper) reconstruct it via a single aliasing-downcast helper
(grid_as_uigrid) that documents the never-independently-allocated
GridData invariant; init/set_grid simplify (share grid_data directly).
Removing the casts is deferred to #252.
entity.texture (new, frozen surface +1): thin get/set over the entity's
own UISprite. Entities render with their OWN texture (default_texture
fallback at construction); the grid's texture only determines cell size.
Setter preserves sprite_index; rejects non-Texture (TypeError),
null-data Texture wrappers (ValueError), and deletion.
Adversarial review fixes folded in:
- set_texture/get_texture guard uninitialized Entity wrappers
(RuntimeError), isinstance errors, and null-data Textures.
- PyUIGridViewType tp_dealloc no longer unconditionally severs
GridData::owning_view: gated on last-owner (#251 use_count pattern)
plus owning-view identity. Previously ANY Grid wrapper GC while the
view lived (e.g. scene.children.append(mcrfpy.Grid(...))) silently
broke entity.grid -> Grid identity and data-layer dirty notification.
Tests: tests/regression/issue_313_entity_grid_data_test.py (texture
semantics, grid-cell-size invariance, entity.grid identity, #251 gate
survival, GridPoint outliving teardown, review-fix guards, owning_view
survival) + tests/unit/entity_texture_test.py. API snapshot golden
re-baselined: exactly +1 surface line (Entity.texture) + writability
probe flip. Docs/stubs regenerated. Native + Emscripten builds verified.
Known edges recorded in docs/api-audit-2026-04.md: texture read-back is
a fresh wrapper each get (no Texture __eq__); sprite_index not
re-validated against a new atlas. Multi-view markDirty broadcast and
pure-GridData wrappers remain deferred to #252. Addresses #314.

Regenerate HTML/Markdown API reference, man page, and type stubs against
current committed HEAD (post API-freeze pass #304-#308, #252 overhaul, and
Phase 3/4/5.1/5.2 changes).
The previous tools/generate_stubs_v2.py hand-maintained hardcoded strings,
which drifted badly: stubs still contained removed module functions
(setScale, findAll, getMetrics, setDevConsole), lacked new types (GridView,
Behavior, Trigger, DiscreteMap, Viewport3D, Entity3D, Model3D, Billboard,
NoiseSource, WangSet, LdtkProject, HeightMap, DijkstraMap, AStarPath,
ColorLayer, TileLayer, etc.), and missed post-overhaul properties
(tile_width/tile_height, sprite_grid, perspective_map, cell_pos, labels,
turn_order, move_speed, etc.).
Rewrite the generator as a runtime-introspection script mirroring
generate_dynamic_docs.py's approach:
- classify mcrfpy members (classes, enums, functions, constants, submodules)
- parse signatures from docstring first line with proper paren-depth tracking
- translate multi-form signatures (foo(x,y) or foo(pos)) to *args/**kwargs
- sanitize docstring '...' placeholder params into '**kwargs'
- emit IntEnum blocks for int-subclass types with uppercase members
- discover delegated methods via instance probing (Grid/GridView -> _GridData)
- conservative property type inference (only accept recognized primitives
and CapitalCase class names in parenthesized hints)
Resulting stubs/mcrfpy.pyi (2069 lines) parses as valid Python.
Markdown/HTML/man-page regeneration is otherwise timestamp-only since the
introspection path was already current -- the stubs were the stale artifact.
Per-entity FOV memory moves from std::vector<UIGridPointState> (two-bool
visible/discovered pairs) to a 3-state DiscreteMap (0=UNKNOWN, 1=DISCOVERED,
2=VISIBLE), exposed as entity.perspective_map. The invariant
visible-subset-of-discovered becomes structural (single value per cell), and
the map is a live, serializable, first-class object rather than an implicit
internal array.
Changes:
- New DiscreteMap C++ class with shared ownership; PyDiscreteMapObject now
holds shared_ptr<DiscreteMap>. UIEntity holds the same shared_ptr.
- New mcrfpy.Perspective IntEnum (UNKNOWN/DISCOVERED/VISIBLE), modelled on
PyInputState.
- entity.perspective_map: lazy-allocated on first access with a grid;
setter validates size against grid and raises ValueError on mismatch;
None clears (next access lazy-reallocates fresh).
- updateVisibility() now demotes 2->1 then promotes visible cells to 2.
- entity.at(x, y) returns grid.at(x, y) when VISIBLE, else None.
- Fog-of-war rendering in UIGridView and UIGrid reads the 3-state map.
- Removed: UIEntity::gridstate, ensureGridstate(), entity.gridstate getter,
UIGridPointState struct + PyUIGridPointStateType.
- Obsolete tests deleted (test_gridpointstate_point,
issue_265_gridpointstate_dangle); 4 new tests cover lazy allocation,
identity, serialization round-trip, size validation, and the
visible-subset-of-discovered invariant.

BREAKING CHANGE: Constructor keyword argument renamed from `click` to
`on_click` for all UIDrawable types (Frame, Caption, Sprite, Grid, Line,
Circle, Arc).
Before: Frame(pos=(0,0), size=(100,100), click=handler)
After: Frame(pos=(0,0), size=(100,100), on_click=handler)
The property name was already `on_click` - this makes the constructor
kwarg match, completing the callback naming standardization from #139.
