plan: approve the review shots, plan collision and facade patches

All nine review shots approved. Roadmap gains the defects the Blender pre-check
already knows about rather than rediscovering them after release: 0.1.1 now names
the 15.8 cm sidewalk edge step, the ~10% crossing ramps, the missing collision
authoring pass and the unverified kerb height. A new 0.1.4 patch plans proper
building facades explicitly - facade kit, procedural materials, Blosm setupScript
styles, hero detail, El Capitan Theatre - and states that the existing geometry is
kept, so shipped blockouts cannot be mistaken for finished architecture.

 ## 0.1.1 — Collision fixes (patch)
 
+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.
+
 ### Patch tasks
 
-- [ ] Audit and fix any collision gaps or fall-through geometry found in `0.1.0`.
+- [ ] **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.
+- [ ] **Crossing ramp gradient.** The kerb-flush transitions measure **10–13 cm over 1.5 m ≈ 10 %**, steeper than the 8 % a real ramp uses (`Geo/tools/street_section.py` output, s≈33, 39, 126 m). Grade the three ramp openings properly.
+- [ ] **Collision authoring pass.** None exists yet: on Unreal import, complex-as-simple for terrain and street (walkable surfaces must not be approximated into ramps over kerbs), simple convex hulls per building. Record the settings in `Docs/build.md`.
+- [ ] **Kerb height is an assumption.** 0.15 m modelled, 0.13 m as built, and the 3DEP DEM cannot resolve a kerb at all. Check against the photographs and record the final figure.
+- [ ] Audit and fix any collision gaps or fall-through geometry found in `0.1.0` in the engine.
 - [ ] Regression-test traversal on both sides of the demo.
 - [ ] Verify no new packaging defects.
 - [ ] Tag `v0.1.1` and write `CHANGELOG.md` entry; then remove this section.

 - [ ] Correct building scale and street proportions flagged against references.
 - [ ] Refine hero façade details where reference photography shows discrepancies.
+- [ ] **Replace the placeholder heights.** Three of the fifteen block buildings carry no OSM height and render at a guessed 6.4 m (`Geo/tools/block_height_report.py`). Measure them off the photographs and correct the blockout.
+- [ ] Resolve the remaining unknown on the hero: the colonnade currently occupies about 45 % of the height against roughly 50–60 % in the photographs. Fix the vertical proportions.

+## 0.1.4 — Proper building façades (patch)
+
+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.
+
+### 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.
+- [ ] **Replace placeholder materials.** Every blockout building currently carries Blender flat colours. Port the procedural generators from `Tools/sibling_asset_audit.py`'s sibling project (`brick_facade`, `seamless_concrete`, `asphalt`) and add stone, render, and glass, then wire them through Unreal material instances.
+- [ ] **Give OSM buildings a façade style.** Blosm exposes `scene.blosm.setupScript` (`setup/neoclassical.py` is the example) so a building can carry a real elevation instead of a plain extrusion. Build one style script for the south frontage and one for the north.
+- [ ] **Hero façade detail pass.** Ionic capitals and fluting, the parapet motto band and medallions as geometry or decal, window rhythm behind the colonnade, and the three portal flights at their photographed proportions.
+- [ ] **El Capitan Theatre (6838) and the retail neighbours.** Model from the 18-frame 5472×3648 reference set; the theatre shares the measured 4.96 m bay rhythm with the temple.
+- [ ] Review every façade change with `Tools/render_screenshots.sh` before tagging.
+- [ ] Tag `v0.1.4` and write `CHANGELOG.md` entry; then remove this section.
