Subject: [PATCH] Add API consistency audit document for 1.0 freeze preparation

Comprehensive catalog of the full Python API surface area:
- 44 exported types, 14 internal types, 10 enums
- 13 module functions, 7 module properties, 5 singletons
- 15 findings across naming, functionality, deprecations, docs

Key findings: camelCase module functions (#304), deprecated
sprite_number (#305), legacy enum string comparisons (#306),
Color missing __eq__ (#307), redundant Grid.position (#308).

+
+## Executive Summary
+
+The McRogueFace Python API exposes **44 exported types**, **14 internal types**, **10 enums**, **13 module-level functions**, **7 module-level properties**, and **5 singleton instances** through the `mcrfpy` module.
+
+Overall, the API is remarkably consistent. Properties and methods use snake_case throughout the type system. The major inconsistencies are concentrated in a few areas:
+
+1. **4 module-level functions use camelCase** (`setScale`, `findAll`, `getMetrics`, `setDevConsole`)
+2. **Terse/placeholder docstrings** on 5 core types (Vector, Font, Texture, GridPoint, GridPointState)
+3. **Deprecated property aliases** still exposed (`sprite_number`)
+4. **Color property naming split**: some types use `fill_color`/`outline_color`, others use `color`
+5. **Redundant position aliases** on Entity (`grid_pos` vs `cell_pos` for the same data)

+
+## Findings: Naming Inconsistencies
+
+### F1: Module-level camelCase functions (CRITICAL)
+
+Four module-level functions use camelCase while everything else uses snake_case:
+
+| Current | Should Be | Status |
+|---------|-----------|--------|
+| `setScale` | `set_scale` | Deprecated anyway (use `Window.resolution`) |
+| `findAll` | `find_all` | Active, needs alias |
+| `getMetrics` | `get_metrics` | Active, needs alias |
+| `setDevConsole` | `set_dev_console` | Active, needs alias |
+
+**Resolution**: Add snake_case aliases. Keep camelCase temporarily for backward compatibility. Remove camelCase in 1.0.
+
+### F2: Color property naming split
+
+Filled shapes (Frame, Caption, Circle) use `fill_color`/`outline_color`. Stroke-only shapes (Line, Arc) use `color`. This is actually semantically correct -- Line and Arc don't have a "fill" concept. **No change needed**, but worth documenting.
+
+### F3: Redundant Entity position aliases
+
+Entity exposes the same cell position data under two names:
+- `grid_pos`, `grid_x`, `grid_y`
+- `cell_pos`, `cell_x`, `cell_y`
+
+Both exist because `grid_pos` is the constructor parameter name and `cell_pos` is more descriptive. **Recommendation**: Keep both but document `grid_pos` as the canonical name (matches constructor).
+
+### F4: Grid `position` alias
+
+`Grid.position` is a redundant alias for `Grid.pos`. All other types use only `pos`. **Recommendation**: Deprecate `position`, keep `pos`.
+
+### F5: Iterator type naming
+
+- `UICollectionIter` -- has "UI" prefix
+- `UIEntityCollectionIter` -- has "UI" prefix
+- `EntityCollection3DIter` -- no "UI" prefix
+
+The "UI" prefix is an internal detail leaking into type names. Since these are internal types (not exported), this is cosmetic but worth noting.
+
+---
+
+## Findings: Missing Functionality
+
+### F6: No `__eq__` on Color
+
+`Color` has `__hash__` but no `__eq__`/`__ne__`. Two colors with the same RGBA values may not compare equal. This is a bug.
+
+### F7: No `Music.pitch`
+
+`Sound` has a `pitch` property but `Music` does not, despite SFML supporting it. Minor omission.
+
+### F8: No `Font` methods
+
+`Font` has no methods at all -- not even a way to query available sizes or get text metrics. This limits text layout capabilities.
+
+### F9: GridPoint has no `__init__`
+
+`GridPoint` cannot be constructed from Python (`tp_new = NULL`). This is intentional (it's a view into grid data) but should be clearly documented.
+
+### F10: Animation direct construction deprecated but not marked
+
+The `Animation` class can still be instantiated directly even though `.animate()` on drawables is preferred. No deprecation warning is emitted.
+
+---
+
+## Findings: Deprecations to Resolve
+
+### F11: `sprite_number` on Sprite and Entity
+
+Both types expose `sprite_number` as a deprecated alias for `sprite_index`. This should be removed before 1.0.
+
+### F12: `setScale` module function
+
+Deprecated in favor of `Window.resolution`. Should be removed before 1.0.
+
+### F13: Legacy string enum comparisons
+
+`Key`, `InputState`, `MouseButton` support comparing to legacy string values (e.g., `Key.ESCAPE == "Escape"`, `InputState.PRESSED == "start"`). This backward compatibility layer should be removed before 1.0.
+
+---
+
+## Findings: Documentation Gaps
+
+### F14: Terse docstrings on core types
+
+Several types have placeholder-quality `tp_doc` strings:
+
+| Type | Current tp_doc | Should be |
+|------|---------------|-----------|
+| `Vector` | `"SFML Vector Object"` | Full constructor docs with args |
+| `Font` | `"SFML Font Object"` | Full constructor docs |
+| `Texture` | `"SFML Texture Object"` | Full constructor docs |
+| `GridPoint` | `"UIGridPoint object"` | Description of purpose and access pattern |
+| `GridPointState` | `"UIGridPointState object"` | Description of purpose |
+
+### F15: Missing MCRF_* macro usage
+
+Some types use raw string docstrings for methods instead of MCRF_METHOD macros. This means the documentation pipeline may miss them.
+
+---
+
+## Recommendations
+
+### Before 1.0 (Breaking Changes)
+
+1. **Remove camelCase functions**: `setScale`, `findAll`, `getMetrics`, `setDevConsole`
+2. **Remove `sprite_number`** deprecated alias from Sprite and Entity
+3. **Remove legacy string enum comparisons** from Key, InputState, MouseButton
+4. **Remove `Grid.position`** redundant alias (keep `pos`)
+5. **Add `__eq__`/`__ne__` to Color** type
+
+### Immediate (Non-Breaking)
+
+1. **Add snake_case aliases** for the 4 camelCase module functions
+2. **Improve docstrings** on Vector, Font, Texture, GridPoint, GridPointState
+3. **Document `grid_pos` vs `cell_pos`** -- state that `grid_pos` is canonical
+
+### Future Considerations
+
+1. Add `pitch` to `Music`
+2. Add basic text metrics to `Font`
+3. Consider deprecation warnings for `Animation()` direct construction
+4. Unify iterator type naming (remove "UI" prefix from internal types)
