## Status

- **Type:** Standalone Lake project (`lakefile.toml`, `lean-toolchain` pinned `v4.32.1`, `lake-manifest.json`)
- **Files:** 12 `.lean` (6 FR + 6 `_en` siblings, EPIC #4980 Pattern A)
- **Files:** see catalogue (FR + `_en` siblings, EPIC #4980 Pattern A)
- **`sorry` count:** 0 (definitions only, no proofs)
- **Mathlib dependency:** None — all files use core Lean 4 only
- **Buildable in isolation:** Yes — `lake build` (harness added by #2752, ai-01 review)
