The archive on disk is Unreal Engine 5.2.0 (CL 25360045, payload dated
2023-05-06), 19.59 GiB, ZIP central directory present and unzip -tq clean.
That contradicts the planned 5.8.x pin, so the decision, its costs, and the
extraction plan are written into Docs/setup.md rather than silently pinned.
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.
New Geo/scripts/street_profile.py measures the 279.4 m block centreline, the
three signalised crossings (20.9-25.9 m across), sidewalk centrelines at 12.6 m
and 13.6 m, and per-building setbacks of 13.0-15.8 m. Derived sidewalk widths
of ~4.0 m south and ~5.3 m north cross-check against the mapped centrelines.
Geo/manifests/local-origin.md fixes EPSG:26911 and the Highland intersection
node as origin, defines the axes and the x100 metre-to-centimetre rule, and
leaves the projected pair blank because PROJ is not installed here.
Records the lane-count discrepancy (4 tagged lanes over a 20.9 m carriageway).
Reference images are development-only material: licensing is not a gate for
local private use, so they are simply never committed. Art/reference/ is now
gitignored; the licensed status of anything shipped is still recorded in
THIRD_PARTY_NOTICES.md.
Adds Tools/commons_fetch.py, which fetches Wikimedia Commons imagery by search
or exact title and writes a provenance sidecar, plus Docs/reference-notes-hollywood.md
recording what each local set is evidence for.
ROADMAP gains an explicit item for licensed photography of the TCL Chinese
Theatre (way 424105908) and Madame Tussaud's (way 424105889). The inventory
records which sibling tools exist, that refcollect.py is unlicensed-tmp-only and
cannot feed committed references, and that the OpenRouter key stays outside this
repository.
Inventory the sibling security-game project and copy only the evidence: nine
licensed photos with their sidecar provenance into Art/reference/hollywood/,
now LFS-tracked. Add the block-wide OSM extract with a manifest, resolve the
demo bounds (Orange Dr -118.341434 .. Highland Ave -118.338718, 279 m) and the
south/north building sets, and add Geo/scripts/block_report.py to reproduce it.
The sibling docs place the El Capitan Theatre west of 6840; OSM geometry and
the house numbering put it east. Recorded with the two unresolved measurement
conflicts rather than averaged.
Nominatim plus the OSM API confirm 6840 Hollywood Blvd as way 424024147
(Hollywood Masonic Temple, Q3139424), footprint ~1387 m2. The neighbouring
El Capitan Theatre is a separate way with a different amenity and size, so the
two stay distinct structures. Raw responses are checksummed in Geo/raw/.
git-lfs 3.7.1 with an active lfs filter, clang 23.1.4, cmake 4.3.0, ninja
1.13.2. The flathub lts branch installed QGIS 3.28.9 on an EOL Qt5 runtime, so
it is recorded as an invalid pin with the replacement path.
vulkaninfo names GPU0 as the discrete RTX 5070 Ti (NVIDIA 615.78.08, API
1.4.351), with the RADV iGPU as GPU1 and llvmpipe as GPU2. Note the device
selection risk for the engine and mark the ROADMAP environment item done.
Deployment 45.20261105 booted (kernel 7.2.15-ogc1.1.fc45). Operator nvidia-smi
confirms the RTX 5070 Ti renders the Wayland session on driver 615.78.08;
vulkaninfo loads instance 1.4.350 but the physical-device line was not captured.
Tooling gaps after the update are listed as current state.
The lfs filter is inactive until 'git lfs install' writes filter.lfs.*, and a
matched file is then stored as a plain blob without any warning. Document that
instead of the wrong claim that git add fails, and add a guard script.
Create Game/, Art/, Geo/, Tools/, Docs/ with LFS and ignore rules, record the
workstation audit, toolchain pins, setup checklist, release checks, and
licensing policy. ROADMAP 0.1.0 environment tasks marked to match verified state.
