docs: release the geo claim and record the tooling traps

 - **Its AI concept frames are restaged photograph references** (`.refgen.json` sidecars point at photos with a "keep geometry fixed" suffix). Useful as art direction, not as texture sources.
 - **Blosm exposes `setupScript`** (`scene.blosm.setupScript` → `loadSetupScript`) for custom building materials, and ships `setup/neoclassical.py` as an example — the hook for giving OSM buildings a per-building facade style instead of flat colours.

+- **One conversion, one place.** `Geo/tools/osm_common.py::to_unreal_local` is the only metres→centimetres conversion; every exporter calls it. `os_common` also needed an explicit `import os` at module level — a helper defined with a function-local import list crashed with `NameError: os` when called from a fresh interpreter.
+- **`asset_metadata.py audit` must recurse.** Sidecars sit next to their `.blend`, which is one level below `Art/blender/`; a flat `glob` found nothing and reported "0 sidecars, 0 problems" — a green result that meant "did not look".
+- **Blender-side builders live in `Art/blender/*/`** (terrain, street, site, blockout) and reach helpers via `os.path.join(HERE, "..","..","..","Geo","tools")`. Moving them breaks the old `"..", "Geo", "scripts"` path silently until the script is run.
+- **Height provenance:** 3 of the 15 block buildings carry no OSM height and Blosm renders them at a placeholder 6.4 m. `Geo/tools/block_height_report.py` lists them; they need heights measured off the photographs before the skyline is believable.

 - [x] Export one MPFB character with baked materials and deform skeleton; verify import. 2026-11-07: MPFB 2.0.18 generated human (19 158 verts, 1.66 m tall) + standard rig with weights (137 bones) + v2 skin baked to a 1024² diffuse texture (`Tools/mpfb_character_export.py`, export preset `ue_character_v1`). Imported headless (`Tools/ue_character_import.py`) into `/Game/Test/Character`: `SkeletalMesh` + 138-bone `Skeleton` + `Material` with the baked `Texture2D` assigned to slot 0. Quirks recorded: 5.8 Interchange skips materials for skeletal FBX imports (finished in script); Blender 5.2 dropped the FBX `armature_nla` option; the baked image needs `image.filepath` set for FBX to reference it.
 - [x] Document initial setup in `Docs/`: engine install, project checkout, fresh-checkout build procedure. 2026-11-07: `Docs/setup.md` reconciled with reality (all engine/bootstrap items marked done with evidence); `Docs/build.md` completed with the fresh-checkout build, packaging, and headless-content-check procedures plus known engine quirks.

 Tools ported 2026-11-07: every geographic script now lives in `Geo/tools/` with `Geo/README.md` listing its purpose, and the Blender-side builders moved next to their outputs in `Art/blender/*/`, importing the shared helpers and the single unit conversion from `Geo/tools/osm_common.py`.
