Probe 22 points with the USGS 3DEP point service: walkable surfaces span 115.65-119.59 m, a 3.94 m relief, so elevation data is required by the AGENTS rule. Grade falls ~3.3 m eastward over the 279 m block (1.2%) and the north sidewalk sits 0.4-0.7 m above the south. 3DEP 1 m is public domain and becomes the chosen source; the tile itself is still to be downloaded. Factored the shared OSM helpers into Geo/scripts/osm_common.py so the street profile and the elevation probe read the same geometry.

## Reference photography (local only, not committed, not shipped)
|
|
|
|
Reference photographs are **not** part of this repository. They live in the gitignored `Art/reference/` tree on the development machine, are used only for internal, private development, and are never built into a build or shipped. `.gitignore` enforces this; nothing under `Art/reference/` may be added, staged, or committed.
|
|
|
|
| Local folder | Source | Provenance |
|
|
| --- | --- | --- |
|
|
| `Art/reference/hollywood/` | Copied 2026-11-06 from `…/06-games/security-game/docs/screens/refs/hollywood/` | That folder's `SIDECAR.md` (author, licence, URL, crop notes) |
|
|
| `Art/reference/north-chinese/` | Fetched 2026-11-06 with `Tools/commons_fetch.py` from the Wikimedia Commons API | `sidecar.json` in the folder |
|
|
| `Art/reference/north-tussauds/` | Same | `sidecar.json` in the folder |
|
|
|
|
What the images are used for, what they are evidence for, and the block's recorded measurements live in [Docs/reference-notes-hollywood.md](Docs/reference-notes-hollywood.md). That document is committed; the images are not.
|
|
|
|
Rules that still apply, because they are about shipped output rather than local working material:
|
|
|
|
- No reference photograph may be shipped, baked into a texture, or distributed. If a shipped asset would otherwise derive from one, that is a licensing decision to be made before the release, recorded here.
|
|
- Venue lettering, signage artwork, and trademarks are separate rights from the photograph. Copying a façade's proportions is not the same as reproducing its signage.
|
|
- A reference image whose provenance cannot be found locally must not be used at all.
|
|
|

## Assets
|
|
|
|
No shipped 3D, texture, or audio assets exist yet. Add a row per asset category with author, source, licence, and redistribution status before the first content commit.
