 tooling that measures them.
 ### Fixed
 - **Sidewalk outer edge ledge.** The sidewalk stood the full 0.15 m kerb height
  above the DEM at both edges, leaving a 15.8 cm lip where the walk route crossed
  from terrain onto the south sidewalk. The upstand now tapers from full at the
  road-side edge to zero at the building-side edge; the north route's worst step
  fell from 15.1 cm to 6.9 cm.
 - **Crossing ramps too steep.** The kerb-flush run was a fixed 1.5 m, giving
  ~8.7 % (measured 10–13 cm over 1.5 m). The run is now derived from a target
  grade (`--max-ramp-grade`, default 8 % ⇒ 1.63 m); the crossing steps 3.4 cm at
  0.25 m sampling.
 ### Added
- **Walk pre-check improvements** (`Art/blender/site/site_assembly.py`): sampling
+- **Façade module kit** at the measured **4.96 m bay** / **3.10 m storey**: pilaster, sill, lintel, window bay, shopfront bay, door bay, cornice, parapet and coping — 16 `SM_` meshes, each validated for manifold topology (12 tris each) and assembled onto **eight buildings, 625 pieces**, from each building's own world bounds.
-  coverage is independent of `--sample` (it previously shrank the route), and the
+- **Generated surface textures** — deterministic stdlib PNGs for ashlar stone, stucco, asphalt and concrete (base colour + roughness), sampled world-aligned with per-material tiling; byte-identical on re-run.
-  report now prints the grade and the arc-length/offset **location** of the worst
+- **Materials**: masonry coursing and roughness variation in the material graphs; `M_FacadeStoneShadow`, `M_FacadeGlass` (specular 0.62 ≈ IOR 1.5) and `M_FacadeBanner`. Material assignment is now **per slot**, keyed on the imported slot material, instead of slot 0 only.
-  step, so a step can be located rather than guessed.
+- **El Capitan Theatre trim**: projecting marquee (12.0 × 2.60 m canopy at a 4.60 m soffit), illuminated fascia, recessed soffit, and a vertical blade sign (1.30 × 5.20 m) with frame and wall bracket.
 - **Visual review loop** (`Tools/visual_loop.py` + `visual_targets.json`): verifies every capture against an expectation (missing, blank, tone-less or wrong-size shots fail) and measures each render against its reference photograph, emitting feedback that names the discipline to consult. Iterations are written under `Art/reference/iterations/`, which is gitignored until a shot is confirmed.
 - **`Tools/fbx_export_preset.py`** — one export preset replacing six copies, and it exports smoothing groups (`FACE`), so round geometry is no longer faceted.
 - **`Tools/ue_common.py`** — clears the read-only bit an LFS `.umap` checks out with and makes a refused save loud.
 ### Changed
- **Kerb height recorded as final** at 0.15 m modelled / 0.13 m as built — a

+
-  height.
+### Fixed
 - **Blockout frame**: the `0.1.2` regeneration had run without `--origin`, shifting the whole frontage ≈119 m in X and 2.4 m in Y and dropping the hero out of the 6902/6838 gap. Regenerated with the affine fit (residual 0.0 cm) and every span re-verified against the block verification notes.
 - **Kit placed ~12 km from its buildings** — it used the mesh-local bounding box, which excludes the actor offset.
 - **Marquee mirrored across the boulevard** (Blender +Y is Unreal −Y) and **hanging 5 cm above the pavement** (absolute Z instead of pavement-relative).
 - **Window bays invisible** inside the solid wall; the surround now projects with glazing inset.
 - **Glazing was not glass**: kit pieces kept the grey material the FBX import creates.
 - **Hero windows floated 1.44 m in front of the wall**; parapet medallions were flat discs on the coping.
 - **Imports could report success while saving nothing** (read-only LFS map), and the north-buildings import failed silently on a missing `import sys`.
 ### Verified
- Site meshes rebuilt and re-imported (7/7, collision flags intact), DemoMap
+- Packaged build `-qaselftest`: walk 761 cm, reset, pause/unpause, seam transect 1456 samples / 0 holes, wall probe 0/35, façade occlusion probe 0/9 — all PASS. Run twice; the harness is time-based and one loaded run reported a false failure.

+## [0.1.3] — 2026-11-09
 Packaging and setup fixes. No gameplay or visual scope; this patch makes the pipeline and its documentation tell the truth about what `0.1.x` taught.
 ### Fixed
 - **Map imports could report success while saving nothing.** `.umap` files are LFS-tracked and check out read-only, so `save_map()` returned `False` with no error and the staged actor vanished on the next load. New `Tools/ue_common.py` (`make_writable`, `require_saved`) clears the read-only bit and makes the failure loud; `ue_hero_facade_import.py` and `ue_import_north_buildings.py` now use it. Verified from a forced `0o444` map: chmod logged, `save_map: True`, exit 0.
 ### Changed
 - `Docs/build.md`: content-pipeline table now lists every step as it exists (seven site FBXs, frontage, north buildings, hero, map) and the shared FBX preset; packaging archive corrected to `Builds/GigLineQA`; the packaged log location and `-qaselftest` usage are documented; new **traps** table covers the read-only save, the hero `--out`-is-the-FBX mistake, the MPFB add-on path, the shot actor quitting under QA, and the null-RHI trace trap.
 - `Docs/setup.md`: the fresh-checkout build is marked verified (2026-11-08) and its blocker closed; a new section documents the two optional keys (`OPENROUTER_API_KEY`, `MAPBOX_ACCESS_TOKEN`) and that neither is needed by the build, the tests or a release.
 - `Docs/Architecture/07_deployment_view.md` and the combined `architecture.md`: build-output path corrected and marked as living outside the repository.
 ### Verified
 - 54 tool tests pass (5 new for `ue_common`).
 - Packaged build still launches into `DemoMap` and `-qaselftest` passes every phase.
 ## [0.1.2] — 2026-11-09
 Scale and façade correction patch. Buildings and the hero elevation now match the reference photography and the cross-checked height data; no new gameplay scope.
 ### Added
 - **`Tools/facade_detail_concepts.py`** — generates frontal building plates (whole elevation, entrance in its façade, building with neighbours) from a local reference photograph through OpenRouter image models. Spec-driven, never overwrites, writes a provenance sidecar per image, output stays in the gitignored `Art/reference/` tree. Local working material only.
 - **`Tools/fbx_export_preset.py`** — the single FBX export preset (`ue_metric_v1` / `ue_character_v1`). Replaces the argument block that had been copied into six exporters.
 - **Façade occlusion probe** in `-qaselftest`: 40 m traces sideways from the road centre at walking height, required wherever a building is staged.
 - **Ionic detail on the hero**: base moulding at every shaft foot, a square abacus over every capital, and a 52-dentil cornice course.
 - **Tool tests**: `Tools/tests/` now covers the input driver, height classification, the Mapbox cross-check, the concept generator and the FBX preset (49 tests).
 ### Changed
 - **Storey height 3.2 → 3.1 m**, calibrated against Mapbox building data, with explicit overrides for three rear outbuildings; the block cross-check now reports 66 matches and no disagreements.
 - **Hero colonnade 47.6 % → 53.1 %** of the 14.50 m elevation, inside the photographed 50–60 % band (thinner entablature and parapet).
 - Blockout regenerated at the new storey height; frontage re-exported and re-imported (6922 42.1 → 39.1 m, El Capitan Theatre 20.0 → 20.5 m).
 - FBX exports now carry smoothing groups (`FACE` instead of `OFF`), so round geometry is no longer faceted and imports stop warning.
 ### Fixed
 - **Windows floated 1.44 m in front of the wall**, ahead of the colonnade; they now sit on the wall plane behind the columns.
 - **Parapet medallions were flat discs lying on the coping** instead of discs on the parapet face.
 - **The hero façade had no usable collision** — the player could walk through it. It is now complex-as-simple; auto-generated convex hulls were tried and rejected because they bulged into the street.
 - **The three "guessed" block heights were never buildings**: two `building=roof` canopies and a transit shelter. They are classified as non-building volumes and the block now reports zero guessed heights.
 ### Verified
 - Packaged build `-qaselftest`: walk, reset and pause pass; seam transect 1456 samples / 0 holes; wall probe 0/35; façade probe 0/9.
 - Screenshots re-rendered for every change and approved by the owner.
 ### Known limitations
 - Cornice dentil spacing, the base and abacus dimensions are recorded assumptions: the reference photography does not resolve them at our scale.
 - Façade surfaces remain flat blockout materials; the textured pass is `0.1.4`.

 ## Packaged Linux build
- 2026-11-07: blank `Game/GigLine` Development build packaged via the command above; 1.1 GiB archive at `/run/media/system/DATA/Builds/GigLine/Linux`; `GigLine.sh` launched on the desktop session, Vulkan swapchain created, 759 frames rendered across a 60 s smoke test. Controls document to be written with the first playable (`0.1.0` Gameplay section).
+Current QA archive: `/run/media/system/DATA/Builds/GigLineQA`. A plain `./GigLine.sh` opens `/Game/Hollywood/DemoMap`; controls are in [controls.md](controls.md) and shown in-game bottom-right. The packaged log is written **relative to the wrapper's working directory**, i.e. `<archive>/Linux/GigLine/Saved/Logs/GigLine.log` — not into the repository.
 Behaviour check without a human at the keyboard:
 ```bash
 cd /run/media/system/DATA/Builds/GigLineQA/Linux
 ./GigLine.sh -windowed -ResX=1280 -ResY=720 -nosplash -qaselftest
 # then read <archive>/Linux/GigLine/Saved/Logs/GigLine.log for "GigLine QA:" lines
 ```
 `-qaselftest` walks for 2 s, resets, pauses/unpauses, sweeps a 16-row seam transect, fires a ground-referenced 21 m wall probe along the street, fires 40 m façade-occlusion traces sideways from the road centre wherever a building is staged, and writes a frame-time series to `Saved/Profiling/`. Every phase logs `... PASS`/`FAIL` and the run ends with `RESULT`.
 ## Traps that cost real time in `0.1.x`
 | Symptom | Cause | Fix |
 | --- | --- | --- |
 | A builder reports success but the asset is unchanged | `.blend`/`.umap` are LFS-tracked and check out **read-only**; Blender and Unreal fail the save quietly | `chmod u+w <file>` first — `ue_build_*`/`ue_hero_facade_import` and every Blender builder need it |
 | `File format is not supported` when reopening a `.blend` | `hero_facade_build.py --out` writes the **FBX**; putting the `.blend` path there overwrites it with FBX bytes | `--out /tmp/…fbx --save-blend Art/…blend --report Art/…json` |
 | `Add-on not loaded: "bl_ext.blender_org.mpfb"` | `mpfb_character_export.py` needs the MPFB add-on visible to Blender | export `BLENDER_USER_SCRIPTS` (see the invocation in [../Art/blender/README.md](../Art/blender/README.md)) |
 | The packaged run exits after a couple of seconds during QA | `GigLineShotActor` runs its screenshot list and quits (`bQuitWhenDone`) | it skips its rounds when `-qaselftest` is on the command line — keep that guard |
 | Headless `-nullrhi` traces report no hits for everything | the null RHI has no physics scene | verify traces in the **packaged** run (`-qaselftest`), never in a commandlet |
 | Import logs "No smoothing group information" for every mesh | `mesh_smooth_type="OFF"` in the FBX export | use `Tools/fbx_export_preset.py` (`FACE`) |

 # `0.1.4` façade review — signoff
 Four demo-map captures from the `facades-0.1.4` branch, after the module kit, the textured materials and the theatre marquee went in. **All seven items signed off 2026-11-09** (owner review of the local renders).
 Reference photographs to compare against: `Art/reference/hollywood/` and `Art/reference/el-capitan-*` (local, not committed). Regenerate the set with `Tools/render_screenshots.sh --verify`; measure it with `python3 Tools/visual_loop.py --compare --iteration 5`.
 ## Signoff
 - [x] **1. Block from the north sidewalk** — hero between its neighbours, sidewalk and road read correctly
 - [x] **2. Street level** — colonnade, shopfronts and window rhythm hold up at eye height
 - [x] **3. Crossing** — zebra bars, kerb line and the frontage behind
 - [x] **4. North buildings** — TCL and Tussaud's framed across the boulevard
 - [x] **5. Materials** — stone reads as coursed stone, glazing as glass, not flat colour
 - [x] **6. Theatre trim** — marquee and blade sign proportions believable at street level
 - [x] **7. Approve** `v0.1.4` (kit + materials + theatre trim); remaining geometry moves to the next version
 ## 1. Block from the north sidewalk
 ![Block from the north sidewalk](../../Screenshots/demo/review-demo-spawn-view.png)
 Expected: the neoclassical hero façade between its neighbours, both sidewalks and the road in the foreground. _Metric: 0.68 similarity, edges 0.28× reference._
 ## 2. Street level
 ![Street level](../../Screenshots/demo/review-demo-street-level.png)
 Expected: the hero colonnade with adjacent frontage buildings either side, shopfronts at pavement level, 4.96 m bay rhythm. _Metric: 0.33, edges 0.27×._
 ## 3. The designated crossing
 ![Crossing](../../Screenshots/demo/review-demo-crossing.png)
 Expected: continental zebra bars on the asphalt at s=130 m, south frontage and colonnade behind. _Metric: 0.42, edges 0.34×._
 ## 4. North-side buildings
 ![North buildings](../../Screenshots/demo/review-demo-north-buildings.png)
 Expected: TCL Chinese Theatre and Madame Tussaud's across Hollywood Blvd, full height in frame. _Metric: 0.34, edges 0.14×._

 ## Appendix — what was checked, and what was broken
 ### Verified
 - **Behaviour**, packaged build, `-qaselftest`: walk 761 cm in 2 s (Z steady 456), reset 0 cm, pause/unpause, seam transect 1456 samples / **0 holes**, wall probe **0/35**, façade occlusion probe **0/9** — all PASS. Run twice: the harness is time-based and one loaded run reported a false failure (`walk 246 cm`, `pause FAIL`), an immediate re-run passed — re-run before believing a single FAIL.
 - **Placement**, probed from the live map against `Geo/verification/2026-11-06-el-capitan-block.md`: 6922 −24276…−17700, 6902 −17749…−14591, **hero −14644…−12028 between them**, theatre −12082…−8210, 6822 / 6806 / 6800 −7854…−1437, TCL −22889…−18442, Tussaud's −27071…−22799. Blockout affine residual **0.0 cm**.
 - **Budgets**: hero 148 parts / 3 044 tris · kit 16 meshes × 12 tris · 625 kit actors ≈ 7 500 tris · 8 × 512² textures (196 KB) · 67 tool tests pass.
 - **Topology**: every kit piece manifold, no loose geometry.
 ### Defects found this cycle
 Every one of these rendered convincingly; the placement ones were caught by coordinate probes, not by looking.
 | Sev | Defect | Root cause |
 | --- | --- | --- |
 | Blocker | Frontage shifted ≈119 m X / 2.4 m Y, hero outside its gap | Blockout regenerated without `--origin` |
 | Blocker | Kit placed ~12 km from its buildings | Used mesh-local bbox; actors carry the offset |
 | Blocker | Marquee on the far side of the boulevard | Blender +Y is Unreal −Y |
 | Major | Marquee canopy 5 cm above the pavement | Absolute Z; pavement is 4.56 m above datum |
 | Major | Window bays invisible, inside the solid wall | Piece modelled entirely at +Y |
 | Major | Glazing wasn't glass | Grey `M_Kit_*` from the FBX import, never overridden |
 | Major | Hero windows floated 1.44 m in front of the wall | Wrong Y in the builder |
 | Major | Parapet medallions were discs on the coping | Built with the Z-axis cylinder helper |
 | Major | Hero had no usable collision | Complex-only; traces use simple |
 | Minor | "No smoothing group information" on every import | `mesh_smooth_type="OFF"` in six exporters |
 | Minor | `save_map()` returned False silently | LFS `.umap` read-only, importer never chmod'd |
 | Minor | North-buildings import silently no-op | Missing `import sys` |
 | Minor | Kit folder held 24 assets (8 orphan materials) | No stale-asset sweep |
 | Minor | Edge-density metric counted PIL's border ring | `FIND_EDGES` leaves a 128 ring |
 | Minor | QA wall probe grazed the theatre wall | Scan row 1 cm from the building line |
 ### Limitations worth knowing
 - Kit pieces are boxes; dentil spacing, abacus and plinth dimensions are recorded assumptions, not measurements.
 - Textures are generated, not authored — no decals, signage text or weathering.
 - The vision pre-check stays advisory: it has rejected shots the owner approved.
 - The low edge ratios in the metrics are partly structural — a wide block view against a tight façade crop always scores low. Weigh the images, not the scores.
 - Performance has not been re-measured since `0.1.0`; the 625 kit actors are unmeasured (tracked in `TODO.md` under `0.1.5`).

 Two tools talk to paid services and read their keys from the gitignored `.env`:

+
 - **All our FBX exporters used `mesh_smooth_type="OFF"`**, which is why every Unreal import logged "No smoothing group information was found for this mesh". The hero now exports `"FACE"` and its round parts are shaded with `shade_smooth_by_angle(35°)` before export: cylinders read as round instead of faceted, and the import warning is gone (6 → 0).
 - **The hero façade had no simple collision** (complex-only), so line traces and capsule sweeps passed straight through it — the player could walk through the wall of the demo. Caught by a new `-qaselftest` **facade occlusion probe** (40 m sideways traces from the road centre at walking height).
 - **Auto-generated convex collision on a 95-part 26 m façade is unusable**: it produced coarse hulls that bulged into the street and the wall probe went 0/35 → 2/35. Rejected in favour of `UseComplexAsSimple` via `UGigLineAssetTools.set_complex_collision_as_simple` (same reason the terrain uses it), saved on the asset.
 - Probe expectations must mirror the staged buildings: the facade probe now carries explicit X spans per frontage (and the TCL/Tussaud's spans on the north side) so a gap between buildings is not reported as a defect.
 ## 2026-11-09 — one FBX export preset instead of six copies
 - The `bpy.ops.export_scene.fbx(...)` argument block was duplicated in six scripts (hero, block frontage, north buildings, site, scale test, MPFB character), and all six carried `mesh_smooth_type="OFF"` — hence the "No smoothing group information was found" warning on every import.
 - Now `Tools/fbx_export_preset.py` holds `ue_metric_v1` and `ue_character_v1`: `preset_kwargs()` (bpy-free, unit-tested) plus `export_static()` / `export_character()` wrappers that import `bpy` lazily. Every caller imports it and passes `selection=True/False`; the seven duplicated blocks are gone.
 - Callers in `Tools/` resolve the module with `sys.path.insert(0, os.path.dirname(os.path.abspath(__file__)))`; the Blender-side `Art/blender/site/export_site_fbx.py` computes the repo root (`..`, `..`, `..`) and joins `Tools`. Getting that wrong silently inserts `Tools/Tools` — check the import path when adding a caller.
 - Verified end to end: scale test, hero, frontage (6/6), site (7/7) and north buildings all re-exported through the preset, re-imported with **0 smoothing warnings**, DemoMap rebuilt and `-qaselftest` all PASS (walk, transect 0 holes, wall probe 0/35, facade probe 0/9).
 - `mpfb_character_export.py` was not re-run: it needs the MPFB add-on on `BLENDER_USER_SCRIPTS` ("Add-on not loaded: bl_ext.blender_org.mpfb"), which is pre-existing and unrelated; the character is not in `0.1.x` gameplay.
 ## 2026-11-09 — v0.1.2 released
 - Cornice finished: projecting corona over a **52-dentil course** (0.18 × 0.30 × 0.22 m at 0.45 m centres, z 12.12–12.34, 0.25 m clear of the corona). Hero is now 3 044 tris across 148 parts, still 14.50 m. Verified: packaged `-qaselftest` all PASS (transect 0 holes, wall probe 0/35, facade probe 0/9).
 - `CHANGELOG.md` gets the `0.1.2` entry (added/changed/fixed/verified/limitations), the `0.1.2` section is removed from `TODO.md`, `ROADMAP.md` status updated, tag `v0.1.2` cut after the merge.
 - Assumptions recorded rather than hidden: dentil spacing, base and abacus dimensions are not resolvable in our reference photography.
 ## 2026-11-09 — elevation cameras levelled (straight verticals)
 - archviz MUST: an elevation must not lean. `hero-facade-front` looked up ~4° from 4.2 m at a 7.6 m target; `demo-spawn-view` and `demo-street-level` were pitched too. All three now put the camera at the target's height, so `FindLookAtRotation` yields pitch 0 and roll 0 and verticals are parallel by construction.
 - Do not try to _measure_ verticality from the rendered PNG with a naive edge scan: banners, windows and the parapet produce different edge sets at different heights and the pairwise match is meaningless (it reported a 418 px "drift"). Verify it geometrically in the camera list instead.
 ## 2026-11-09 — 0.1.3 packaging/setup fixes
 - **`Tools/ue_common.py`**: `make_writable()` clears the read-only bit an LFS `.umap` checks out with (otherwise `save_map()` returns False with no error and the staged actors vanish), and `require_saved()` makes that failure visible. `ue_hero_facade_import.py` and `ue_import_north_buildings.py` never did this — which is why importing the hero appeared to succeed while saving nothing. Verified by forcing `chmod u-w` on DemoMap first: the run logged `map writable: chmod u+w … (was 0o444)`, then `save_map: True`, exit 0.
 - Gotcha while adding it: `ue_hero_facade_import.py` had **no** `import os`/`sys` (only `unreal`), so the sys.path line raised `NameError: name 'sys' is not defined` inside the commandlet — an exit code of 255 with no obvious cause.
 - Docs: `build.md` gained the current pipeline table (7 site FBXs, frontage, north, hero, map), the `Builds/GigLineQA` archive, the packaged-log path, `-qaselftest` usage and a **traps** table; `setup.md` marks the fresh-checkout build verified and documents the two optional API keys; architecture 07 + combined doc corrected the build-output path.
 ## 2026-11-09 — 0.1.4 materials + architecture-camera pass
 - **Material graphs**: `ensure_material()` now supports masonry coursing (`courses_m`) and roughness variation. **UE's `WorldPosition` is in CENTIMETRES**, so a course height in metres must be ×100 — the first attempt divided by 0.55 and produced coursing 100× too fine to see.
 - **`connect_material_expressions` returns False instead of raising**, so an unknown pin name leaves an input unconnected and the material silently compiles with a default (a mask of 0 is invisible). All links now go through a `link()` helper that logs failures. There is also **no `MaterialExpressionLess`**; use `Frac → Divide → OneMinus → Clamp` for a soft threshold band, or `MaterialExpressionStep`/`SmoothStep` if a hard one is wanted.
 - **Material assignment was slot-0-only**, which on the hero is the _banner_ — the stone, shadowed stone and glazing kept their flat Blender materials. Assignment is now per slot, keyed on the imported slot material's name (`glass`/`banner`/`stoneshadow`/`stone`/`roof`/`wall`). Hero: 4/4 slots.
 - New materials: `M_FacadeStoneShadow` (same coursing, a stop darker), `M_FacadeGlass` (roughness 0.14, specular 0.62 ≈ IOR 1.5 expressed without a refraction pass), `M_FacadeBanner` (the one saturated surface).
 - **Camera FOV**: levelling the elevation cameras left the building small in frame (39 % sky). Added optional per-shot `ShotFieldOfView` to `AGigLineShotActor` and a 4th element on the shot tuples; a long lens (42–55°) fills the frame from across the street while the camera stays level, so verticals stay parallel. `review-hero-facade-front` sky 39 → 20 %, `demo-spawn-view` 23 → 16 %.
 ## 2026-11-09 — facade texture maps (0.1.4)
 - `Tools/generate_facade_textures.py` writes deterministic 512² base-colour and roughness maps (ashlar stone, stucco, asphalt, concrete) with a pure-zlib PNG encoder and hash-based value noise — no numpy/Pillow, ~14 s for all eight, and byte-identical on a re-run (checked by md5sum).
 - `ue_build_demo_map.py` imports them to `/Game/Hollywood/Textures` and samples them **world-aligned**: WorldPosition (cm) → ×(1/tile_cm) → ComponentMask(R,G) → TextureSample UVs. `tile_cm` per material: stone 440, stucco 260, asphalt 900, concrete 250.
 - Gotchas: `MaterialExpressionTextureSample`'s UV input pin is **"UVs"**, and the output pin for colour is **"RGB"** / roughness **"R"**. `ComponentMask` pins are R/G/B/A booleans. A textured material skips the graph coursing on purpose — overlaying both would double the course pattern.
 - The script needs `ROOT` in `ue_build_demo_map.py` and `sys` imported; forgetting either fails with `NameError` and an exit code of 0 from the commandlet (always read the result file under /tmp/gigline).

 - `Tools/facade_kit_build.py` builds the kit at the measured **4.96 m bay** and **3.10 m storey**: pilaster, sill, lintel, window bay, shopfront bay, door bay, cornice, parapet + coping = 16 meshes, exported per-object with `fbx_export_preset` plus a JSON part report (dims + evidence per piece).
 - `Tools/ue_import_facade_kit.py` → `/Game/Hollywood/Kit/*`, complex-as-simple collision (a convex hull would fence off the shopfront glazing).
 - `Tools/ue_apply_facade_kit.py` lays the kit out from each building's own bbox: `bays = round(width / 496 cm)`, storeys from height minus the 310 cm ground floor. **638 pieces** over six frontage buildings + both north buildings.
 - **Bug worth remembering:** the first window piece was modelled entirely at +Y (into the wall), so every window sat _inside_ the solid blockout wall and was invisible in every render while the placement maths looked right. The kit now projects the surround 3 cm proud with the glazing 6 cm behind its face — a solid-wall blockout cannot carry a real recess, so the piece has to project.
 - Blender gotcha: clearing the scene _including materials_ invalidates handles already taken ("StructRNA of type Material has been removed"); clear objects and orphan meshes only, and create the material after the clear.
 - The kit meshes are spawned at the world origin with their position baked into the mesh (like the frontage exports), so placement uses the bbox directly and must not add the actor location.
 ## 2026-11-09 — CRITICAL: blockout must be regenerated with --origin
 - Regenerating the blockout in 0.1.2 (for the 3.1 m storey height) was run **without `--origin`**, so Blosm centred on the extract instead of fitting the project frame. The whole frontage shifted about **119 m in X and 2.4 m in Y**, and the hero ended up outside the 6902/6838 gap — the "verified placement" was undone silently, and every render still looked like a plausible block.
 - Correct invocation (README documents it, and the affine fit prints `frame correction residual: max 0.0 cm`): `blosm_blockout.py --osm … --bounds 34.1006,-118.3422,34.1020,-118.3370  --level-height 3.1 --origin 34.101545,-118.338718 --assets-dir … --out …`
 - After re-export + re-import, the frontage spans are back to the verified values: 6922 −24276..−17700, 6902 −17749..−14591, **hero −14644..−12028 between them**, theatre −12082..−8210, and the north buildings at −22889..−18442 / −27071..−22799.
 - **`ue_import_north_buildings.py` also lacked `import sys`**, so its sys.path line raised NameError and the import silently did nothing (exit 255). Same trap as the hero importer: these scripts imported only `unreal`.
 - Lesson: after any blockout regeneration, probe the staged buildings' world X spans and compare them with `Geo/verification/2026-11-06-el-capitan-block.md` before trusting a render. A shift of this size is invisible in a screenshot.
 ## 2026-11-09 — kit naming + topology validation (blender-modeler checklist)
 - Kit assets now follow the Unreal convention: the Blender object keeps its readable name (`Kit_Pilaster`), the exported asset and file are `SM_Kit_Pilaster`. The kit loader strips the `SM_` prefix so the layout code still addresses pieces by short name.
 - `facade_kit_build.py::validate()` runs the blender-modeler cleanup checklist on every piece before handoff — non-manifold edges, loose vertices, triangle count — and records the result in the part report. Current kit: 16 pieces, **all manifold, no loose geometry, 12 tris each**.
 - `ue_import_facade_kit.py` now deletes kit assets that the current build no longer produces, so a rename cannot leave two generations of the same piece in the folder (the rename from `Kit_*` to `SM_Kit_*` did exactly that until it did).
 ## 2026-11-09 — visual comparison loop; screenshots are demo-only
 - `Tools/visual_loop.py` closes the reference → render → feedback loop. `--verify` gates captures against `Tools/visual_targets.json` (blank, tone-less, wrong-size fail); `--compare` measures luma, RMS contrast, edge density, palette distance and a 3x3 luma grid against the reference and prints a 0–1 score; `--iteration N` writes `Art/reference/iterations/N/{metrics.json,feedback.md}`. The feedback names the skill to consult, so the next modelling pass starts from a measurement rather than an opinion.
 - **Iterations are gitignored** (`/Art/reference/iterations/`); only confirmed shots are promoted into `Screenshots/`. A test asserts the ignore rule and that every target is a demo-map shot.
 - `Screenshots/` now holds **demo-map captures only** — the review staging map is no longer rendered for review. `render_screenshots.sh --verify` renders the demo map, collects the shots and runs the verification gate in one step.
 - **PIL gotchas:** `FIND_EDGES` leaves its own border ring at 128 (236/3600 px on a 60x60 frame = 6.5% "detail" on a perfectly flat image), so crop **after** filtering — cropping before does not help, the new border gets the same treatment. Palette shares must divide by the full-image area, not the cropped one.
 - First comparison (iteration 2): spawn view 0.70, street level 0.35, crossing 0.41, north buildings 0.34. Edge density is the dominant gap everywhere (0.04–0.11 against 0.20–0.32 in the references) — the render still lacks the relief the photographs carry, which is exactly what the `0.1.4` façade work is for.
 ## 2026-11-09 — theatre marquee + blade sign
 - `Tools/theatre_trim_build.py` builds the El Capitan Theatre's signature features in **world coordinates**: marquee canopy 12.0 × 2.60 m at a 4.60 m soffit, illuminated fascia, recessed soffit, vertical blade sign 1.30 × 5.20 m with frame and bracket. `Tools/ue_stage_theatre_trim.py` imports to `/Game/Hollywood/Theatre` and stages one actor per piece (single spawn at the origin — no placement arithmetic).
 - **Two placement bugs, both invisible in a render:**
  1. **Axis sign.** Blender +Y is Unreal −Y, so a face at Unreal Y +1001 is Blender Y −10.01. Using +10.01 put the whole marquee on the far side of the boulevard.
  2. **Absolute Z.** Trim heights were absolute while the pavement at the theatre is 4.56 m above the project datum, so the canopy hung 5 cm above the pavement — the QA wall probe caught it as a knee-height blocker. `GROUND_Z` now offsets every height.
 - Wall probe: a scan row at Y 1000 sat ~1 cm from the frontage building line and grazed the theatre wall once the kit's proud shopfronts went in. Rows now sample the street envelope only (−1400, −167, 800, −1382, 718).
 ## 2026-11-09 — 0.1.4 signed off; 0.1.5 created for the carried geometry
 - Owner reviewed the four demo captures locally and approved the set. Signoff recorded in `Docs/reviews/0.1.4-review.md` (7/7 items) and in the per-shot `Approved` column of `Screenshots/README.md`.
 - The three geometry items that `0.1.4` did not finish — retail neighbours from their own references, hero fluting/motto band, blockout cleaning — move to a new **`0.1.5` Façade finishing** patch rather than growing this one, plus a much-needed **1440p performance re-measure** (625 kit actors have never been measured; `0.1.0` measured 414 fps).
 - Decision recorded because it sets a precedent: finish and sign off a version when its _stated_ scope is done, and carry leftover scope into the next patch — do not let a patch accumulate unmeasured geometry.

+Each shot has an **expectation** in [`Tools/visual_targets.json`](../Tools/visual_targets.json) — the content the capture must show — and a verification state produced by `--verify`: it fails if the frame is blank, the wrong size, or has no tonal range.

 ## Scene conventions
- **Review map** (`/Game/Test/ReviewMap`): 160 m floor, top face at Z 0; the character measures Z 0..83 cm. One warm key light plus sky fill.
+- **Demo map** (`/Game/Hollywood/DemoMap`): fixed daytime — sun pitch −62 / yaw 120 (intensity 4, warm), sky light 2.6, sky atmosphere, height fog, fixed exposure.
- **Cubes**: `Cube_ScaleTest_A` rests on the floor, `Cube_ScaleTest_B` floats at Z 2 m; both are exactly 1 m — the scale reference.
+- **Cameras**: elevation shots sit at their target height (pitch 0, so verticals stay parallel) and use a 42–55° lens to fill the frame from across the street.
- **Demo map** (`/Game/Hollywood/DemoMap`): fixed daytime — sun at pitch −50 / yaw 120 (intensity 4, warm), sky light 2.6, sky atmosphere, height fog, fixed exposure.
+- **Materials**: every surface carries a look-developed material from `Tools/ue_build_demo_map.py` — noise-blended base colour, masonry coursing, and a generated texture set (`Tools/generate_facade_textures.py`) sampled world-aligned. Explicit roughness and specular per surface type.
 - **Materials**: every exported surface carries a look-developed material built in `Tools/ue_build_demo_map.py` (`ensure_material`) because Blender's flat diffuse colours do not survive the FBX → Unreal import. Each has an explicit roughness and a subtle world-space noise blend between two shades: `M_Asphalt` (0.92), `M_Concrete` (0.88), `M_KerbConcrete` (0.85), `M_Ground` (0.98), `M_RoadPaint` (0.62), `M_FacadeStone` (0.72) and `M_Stucco` (0.86) for the north-side buildings.
 - **Lighting is dynamic-only** (`r.AllowStaticLighting=False`, all lights Movable), so no lighting build is ever required.
 ## What to look for
 - **Ground contact**: feet meet the plane with no gap and no shadow seam.
 - **Scale**: everything checks against the 1 m cubes.
 - **Façade rhythm**: six columns at 4.96 m across 25.75 m should read as the photographs in silhouette.
 - **Frontage heights (new in this round)**: 6922 and the El Capitan Theatre were re-cut to the 3.1 m storey height. Check they still read as the taller west end and the lower cinema respectively against `Art/reference/hollywood/el-capitan-theatre-blade-sign-day-wikimedia-2008-10.jpg`, and that the ordering of the six frontage buildings is unchanged.
 ## Known cosmetic issues
- Floor speckle from the `Constant3Vector` wiring in `Tools/ue_build_review_map.py`.
+- Hero façade renders pale: the stone material is a graph and a texture set, not a scanned surface (the `0.1.4` façade pass is in progress).
- Hero façade renders pale — Blender flat colours with no normal/roughness, so it reads as untextured stone (the `0.1.4` façade patch, not a lighting bug).
+- Banners sit on the column line rather than flush to the wall (they hang on the columns in the photographs, so this is acceptable).
- Banners and window panels float detached from the colonnade wall (next modelling pass).
+- Between kerb and building line the walkable surface is the terrain mesh, not a modelled pavement.

+The `0.1.4` kit, materials and theatre trim are signed off; these are the geometry items that were carried forward rather than grown inside that patch.
 - [x] Correct building scale and street proportions flagged against references. **Mapbox adopted 2026-11-09.** `Geo/tools/mapbox_buildings.py` merges our OSM heights with Mapbox's building data for the same footprints; after adopting its two findings the cross-check reports **66 match, 6 non-building, 0 disagreements**. Adopted: **`LEVEL_HEIGHT` 3.2 → 3.1 m** (`block_height_report.py`, and the Blosm `--level-height` default), plus explicit `HEIGHT_OVERRIDES` (3.0 m) for the three rear `building=yes`/`apartments` structures Mapbox gives as single-storey. Blockout regenerated, frontage re-exported/re-imported, DemoMap rebuilt; packaged `-qaselftest` all PASS. Measured effect: 6922 42.1 → 39.1 m, El Capitan Theatre 20.0 → 20.5 m (both now ~1.9 m above their table height = roof mass).
 - [ ] Refine hero façade details where reference photography shows discrepancies.
 - [x] **Replace the placeholder heights.** **Resolved 2026-11-08 — they were never unknown buildings.** The three "guessed" ways are not building volumes at all: `1360755125` and `1360755126` are `building=roof` at `layer=1` (elevated canopies) and `1417995292` is `amenity=shelter` / `shelter_type=public_transport` (a transit shelter). The report defaulted them to "2 levels × 3.2 m" and produced the bogus 6.4 m. `Geo/tools/block_height_report.py` now classifies roof/shelter explicitly and reports **0 guessed heights**: all 15 block volumes have a real `height` tag, a `building:levels` derivation, or are correctly excluded as non-building volumes. No photograph measurement was needed, and no frontage building was affected.
 - [x] 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. **Fixed 2026-11-09.** Measured baseline: colonnade (columns + capitals) 6.90 m of the 14.50 m envelope = **47.6 %**, because the entablature (3.40 m) and parapet (2.20 m) left only 7.90 m for the order. Thinned both to **3.00 m** and **1.80 m** (`Tools/hero_facade_build.py`), which lifts the colonnade to **7.70 m = 53.1 %** — inside the photographed 50–60 % band, with the 14.50 m envelope, the motto band and the medallions unchanged in position relative to the parapet. Hero rebuilt, re-imported (bounds 2604 × 1257 × 1450 cm) and re-rendered.

 ## 0.1.3 — Packaging and setup fixes (patch)
 Suggested blender skills: **export-pipeline** and **unreal-export** (scale/pivot/normals/materials/collision verification) if any packaging defect traces back to the Blender export presets.
 ### Patch tasks
- [ ] Fix any packaging or build issues encountered in `0.1.x`.
+- [ ] **Retail neighbours (6822 Budget, 6806–6820, 6800 Lee Drug) from their own references.** The 18-frame set is the El Capitan Theatre, so it cannot stand in for these façades. Fetch or shoot per-building references first, then model the shopfront line and upper storeys rather than relying on the kit alone.
- [ ] Update `Docs/` setup instructions for anything that changed.
+- [ ] **Hero façade: fluting and the motto band as geometry.** The colonnade is plain cylinders and the motto/medallions are flat panels; both are legible in the reference photography.
- [ ] Tag `v0.1.3` and write `CHANGELOG.md` entry; then remove this section.
+- [ ] **Blosm blockout cleaning pass.** Roofs and facades remain untextured volumes and the `setupScript` styles stay unused; with the kit carrying the elevations, this is now cleanup rather than a second façade system.
-
+- [ ] **Re-measure 1440p performance** with 625 kit actors and 8 generated textures in the map. `0.1.0` measured 414 fps average, so there is headroom, but it has not been re-run since.
-## 0.1.4 — Proper building façades (patch)
+- [ ] Tag `v0.1.5` and write `CHANGELOG.md` entry; then remove this section.
 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
 - [ ] **Finish the Blosm blockout cleaning/detailing (moved from the deferred `0.1.0` item).** Import state: `Art/blender/blockout/blockout-2026-11-06.blend` (86 meshes, EPSG:26911, 0.0 cm affine residual) with cleaning tooling in `Geo/tools/` and `Art/blender/blockout/blosm_blockout.py`. To do here: (a) untextured roofs/facades → **Replace placeholder materials** below; (b) Blosm `setupScript` façade styles → **Give OSM buildings a façade style** below; (c) the 3 of 15 buildings lacking height data are the `0.1.2` placeholder-heights item.
 - [ ] **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.

 | `ue_common.py` | Shared helpers for the Unreal commandlet scripts: `make_writable()` clears the read-only bit an LFS `.umap` checks out with (otherwise `save_map()` returns False silently), and `require_saved()` makes that failure explicit. |

Never overwrites (writes `-v2`, `-v3`), writes a `.refgen.json` sidecar per image (model, prompt, source photo, SHA-256), and puts everything under `Art/reference/facade-details/` — gitignored, local-only, never shipped. Costs money per image, so it is never automatic. |

 """Generate frontal building plates from the local reference photography.
 Each study takes one photograph we already hold (`Art/reference/`, gitignored) as
 the geometric anchor and asks an image model to re-stage it as a clean **frontal
 view of the building** — the whole elevation, the entrance in its facade, or the
 building with its neighbours — evenly lit, no crowd, no staging, so the modelling
 pass has something measurable instead of a tourist photo.
 Deliberately **not** close-up detail crops: a doorway or cornice crop cannot be
 measured for proportion, which is what the modelling pass actually needs.
    python3 Tools/facade_detail_concepts.py --list
    python3 Tools/facade_detail_concepts.py --only door-recess,parapet-motto
    python3 Tools/facade_detail_concepts.py --all
    python3 Tools/facade_detail_concepts.py --all --model google/gemini-2.5-flash-image
 Output: `Art/reference/facade-details/<study>.png` plus a `<study>.refgen.json`
 sidecar recording the model, the source photograph, the prompt and the SHA-256 of
 the result. `Art/reference/` is gitignored, so **neither the images nor the
 sidecars are committed** — they are local working material. The study list and
 the tool are the committed part.
 Design notes
 ------------
 * Standard library only: the OpenRouter chat-completions call is `urllib`, and
  the returned `data:` URL is decoded with `base64` and written straight to disk.
 * An existing output is never overwritten; `-v2`, `-v3` … are used instead, so
  re-running after a prompt edit keeps both studies comparable.
 * Generation costs money, so it is never automatic: `--list` is free, and every
  generating run prints the model and the study count first.
 * The token is read from `OPENROUTER_API_KEY` or the ignored `.env` and is never
  written to a sidecar or a log line.

 """Build the reusable façade module kit (0.1.4).
 One module, measured: the **4.96 m bay** (the hero's column rhythm, which the
 El Capitan Theatre next door shares per the reference notes). Every block building
 should assemble from the same pieces instead of being a bare extrusion, so the
 street wall gets a consistent window rhythm, shopfront line, cornice and parapet.
 Pieces (`ue_metric_v1`, metres, origin at the module's bottom-front centre so a
 building can place them by bay index and storey index):
    Kit_Pilaster      vertical pier on a bay boundary
    Kit_Sill          window sill band
    Kit_Lintel        window head / lintel band
    Kit_WindowBay     recessed window opening in one bay (glass + reveal)
    Kit_ShopfrontBay  ground-floor shopfront: piers, glass, fascia
    Kit_DoorBay       entrance bay: recessed door, jambs, threshold
    Kit_Cornice       projecting cornice band, one module long
    Kit_Parapet       parapet wall + coping, one module long
 Dimensions come from the measured storey height and the reference photography
 where it resolves them (window proportions, shopfront line); everything the
 photographs do not resolve is an assumption and is recorded as one in the part
 report, so model and evidence stay separable.

 Before this module the same `bpy.ops.export_scene.fbx(...)` argument block was

 character). They had already drifted only by accident, and every one of them
 carried `mesh_smooth_type="OFF"` — which is why Unreal logged "No smoothing group

 Why these values:

  at exactly ×100, verified by the three-cube scale test (1 m → 100.00 uu).
 * `axis_forward="-Y"`, `axis_up="Z"` is the project's recorded mapping: east → +X,
  north → −Y, up → +Z.
 * `mesh_smooth_type="FACE"` exports smoothing groups. `"OFF"` (the old value)
  drops them, so Unreal rebuilds flat normals and every cylinder is faceted.
 * `use_mesh_modifiers=True` bakes the bevel/modifier stack at export; the source
  `.blend` stays non-destructive.
