 - [x] Download reference photography for the two north-side buildings inside the 50 m buffer — TCL Chinese Theatre (OSM way 424105908, 6925 Hollywood Blvd) and Madame Tussaud's (way 424105889, 6933 Hollywood Blvd). Done 2026-11-06 with `Tools/commons_fetch.py` against the Wikimedia Commons API: eleven frames in the local `Art/reference/north-chinese/` and `Art/reference/north-tussauds/`, provenance in each `sidecar.json`, nothing committed.
 - [x] Model hero façade for the El Capitan Entertainment Centre site. **Second pass built 2026-11-07** (proportions recalibrated from the 2009 photograph: entablature 3.4 m, parapet 2.2 m, architrave and cornice bands, square pedestals — the first pass had 5.7 m of blank wall above the capitals and read as a warehouse). **First pass built 2026-11-07** (`Tools/hero_facade_build.py` → `Art/blender/hero/hero-facade-2026-11-07.blend` + JSON part report with evidence per part → `Tools/ue_hero_facade_import.py` → `/Game/Hollywood/ElCapitan/SM_HeroFacade`, 1892 tris, 4 materials, placed on the measured building line). Six columns at 4.96 m over the 25.75 m frontage, plinth, three portal flights (5 risers, not the old 8), entablature 2.2 m, parapet 1.6 m with motto band and medallions. **Screenshot review pending** (`Screenshots/review-04`, `review-05`). Next pass: portal recesses read from the street, banner and window placement, then materials.
 - [ ] Model surrounding block frontage.

+- [-] Model simplified background buildings directly across Hollywood Boulevard. Owner: this session (01a1b26b). Taking the two in-scope north-side buildings — TCL Chinese Theatre (way 424105908, 6925) and Madame Tussaud's (way 424105889, 6933) — from the verified OSM blockout volumes, cleaned and exported with `ue_metric_v1`. Source positions measured: TCL centre (Blender local −206.50, 56.20), Tussaud's (−249.47, 47.20); hero façade placed in the demo map at Unreal (−10722.5, −1443.0).
 - [-] Build sidewalks, roads, and collision meshes. Terrain, road, sidewalks and kerbs exist (`Art/blender/terrain/`, `street/`) and are assembled in `site/site-2026-11-06.blend`; collision and details (crossing markings, kerb radii, aprons) are not built. Ground must follow the DEM: 3.94 m fall along the block, ~2 % crown between the gutters at ±10–11 m from the centreline, north sidewalk higher than south. Kerb height is an unresolved assumption — the DEM does not resolve it (`Geo/verification/2026-11-06-cross-sections.md`).
 - [ ] Materials and look development for all exported assets.

 Planned now, applied after `0.1.0` ships. Collision is not authored yet, so these are the defects already visible in the Blender pre-check; the engine pass will add to this list rather than replace it.
 
+Suggested blender skills: **collision-proxy** (UCX/UHX naming, convex hulls, simple collider meshes — the core of the authoring pass), **qa-review** (validation checklists, viewport screenshots, ship/no-ship verdicts for the audit), **asset-optimization** (pre-export validation of every collider). Note: these skills assume MCP-driven Blender; use them as method guides for the headless scripts.

 ### Patch tasks
 
 - [ ] **Sidewalk outer edge against terrain.** The pre-check measured a **15.8 cm** step where a walk sample crosses from `Terrain_DEM` onto `Sidewalk_South` (`Art/blender/README.md`, s≈207 m). Mostly hidden by buildings; visible wherever the frontage is missing. Fix by extending the sidewalk mesh to meet the terrain, or by lowering the outer lip.

 Planned explicitly so the shipped blockouts are not mistaken for finished architecture. **The existing geometry is deliberately kept** — this patch replaces surfaces and detail, not footprints or massing.
 
+Suggested blender skills: **procedural-modeling** + **geometry-nodes** (the façade module kit — bay, pilaster, cornice, parapet, window, shopfront, door — as reusable node groups), **archviz** (real-world scale and façade composition), **materials** (procedural brick, concrete, stone, render, glass — the ported generators), **texture-workflow** (AO/curvature/normal bakes and decals for the motto band and medallions), **uv-workflow** (texel density and modular UV layouts for the kit), **scene-assembly** (assembling kit pieces onto the fifteen block buildings), **lookdev** (screenshot-comparison loop until shading reads correctly), **historical-worlds** or **realistic-style** (1920s Hollywood Blvd neoclassical direction), **asset-optimization** + **unreal-export** (pre-export validation, `ue_metric_v1` preset), **qa-review** (final gate before the `Tools/render_screenshots.sh` review).
+
 ### Patch tasks
 
 - [ ] **Define the façade module.** One set of reusable pieces (bay, pilaster, cornice, parapet, window, shopfront, door) at a fixed module, exported with the `ue_metric_v1` preset so every building assembles from the same kit.
