common_fetch was out of material, so an OpenRouter web-search call (gpt-5.2, openrouter:web_search) returned candidate photo pages and page_image_fetch.py resolved each og:image and downloaded it, recording page URL and hash locally. Four frames kept, including the clearest entrance view yet. The frames overturn the inherited 'eight stone steps, 12 m wide': the entrance is three portals with individual short flights. Recorded as a resolved conflict with the photographs as evidence.

# Tools
|
||
|
||
Repeatable import/export and processing helpers. Anything that was done twice by hand belongs here.
|
||
|
||
## Conventions
|
||
|
||
- One script, one job. No interactive prompts; every input is an argument.
|
||
- Each script documents its input format, output format, and the exact tool version it was tested with.
|
||
- Blender scripts run headless (`blender --background --python`), so they can be re-run for a regression check.
|
||
- No credentials, no absolute machine paths, no writes outside the project by default.
|
||
- A script that produces game content logs what it produced, so `Game/Content` can be audited against it.
|
||
|
||
## Helpers
|
||
|
||
- `check-lfs.sh` — repository guard: fails if `git-lfs` or the `lfs` filter is missing, or if an LFS-tracked file was committed as a plain blob.
|
||
- `site_assembly.py` — assembles terrain + street + blockout into one file and raycasts the walking routes for holes and steps.
|
||
- `street_mesh.py` — road, kerbs, and sidewalks on the DEM, in the project frame; kerbs flush at the three crossings.
|
||
- `terrain_from_dem.py` — terrain grid from the committed DEM, with building footprints cut out.
|
||
- `blosm_blockout.py` — headless Blosm import of the committed `.osm` extract into a `.blend`, with a per-building scale report. Exact invocation in `Art/blender/README.md`.
|
||
- `page_image_fetch.py` — resolves a web page's `og:image` and downloads it, with page URL and hash in a local sidecar. Works for Flickr, Commons file pages, and most photo blogs.
|
||
- `commons_fetch.py` — Wikimedia Commons reference fetcher. Search, exact `File:` titles, or a whole Commons category (`--category`), thumbnails, provenance `sidecar.json` per folder. Wikimedia throttles `upload.wikimedia.org` (HTTP 429), so keep batches to six or fewer files and pass `--delay 3`; a throttled file is skipped and recorded rather than aborting the run. Writes only into the gitignored `Art/reference/`; reference images are never committed.
|
||
|
||
## Planned helpers
|
||
- Blender export preset runner (named presets, metric scale assertion)
|
||
- Blender→Unreal scale test (export a known-size cube, verify 100× conversion)
|
||
- OSM extract fetch and manifest writer (records date, bounds, checksum)
|
||
- QGIS processing steps as batch scripts, so the geo cleanup is reproducible rather than GUI-only
