release: v0.1.4 signoff, changelog entry; carry remaining geometry to 0.1.5

- Review doc: all seven signoff items ticked (owner reviewed the local renders).
- Screenshots README: per-shot Approved column, 4/4 approved 2026-11-09.
- CHANGELOG: full 0.1.4 entry (kit, textures, materials, theatre trim, visual loop,
  the five placement/collision fixes, verified results, limitations).
- TODO: 0.1.4 section removed; new 0.1.5 'Facade finishing' patch carries the retail
  neighbours (from their own references, not the theatre's), hero fluting and motto
  band, the blockout cleaning pass, and a 1440p performance re-measure with the kit
  in the map.
- ROADMAP status updated.

+## [0.1.4] — 2026-11-09
+
+Building façades. The block goes from flat extruded boxes with flat colours to coursed, textured surfaces assembled from a reusable module kit, and the El Capitan Theatre gets the marquee and blade sign that make it read as itself.
+
+### Added
+
+- **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.
+- **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.
+- **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.
+- **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
+
+- **Elevation cameras** are levelled (pitch 0, so verticals stay parallel) and use a 42–55° lens to fill the frame from across the street.
+- **`Screenshots/` holds demo-map captures only**; the review staging map is no longer rendered for review. Each shot carries its expected content and an approval state.
+
+### 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
+
+- 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.
+- All eight buildings probed against the verified world spans.
+- 67 tool tests pass.
+
+### Known limitations
+
+- Kit pieces are boxes; cornice dentil spacing, abacus and plinth dimensions are recorded assumptions.
+- Textures are generated, not authored: no decals, signage text or weathering maps.
+- The vision pre-check remains advisory — it is unreliable on this content.
+- Retail neighbours, hero fluting and the blockout cleaning pass move to `0.1.5`.
+- Performance has not been re-measured since `0.1.0`; 625 kit actors are unmeasured.

 ## 2026-11-09 — Mapbox calibration adopted into the blockout
 
 - Owner decision: adopt Mapbox. Applied:
-  - `LEVEL_HEIGHT` 3.2 → **3.1 m** in `Geo/tools/block_height_report.py`, and the
-    Blosm `--level-height` default in `Art/blender/blockout/blosm_blockout.py`.

-    1492747608 → 3.0 m (Mapbox single-storey; the 2-level guess gave 6.4 m).

-    overrides apply; `mapbox_buildings.py` passes it, so the cross-check agrees

 ## 2026-11-09 — hero colonnade proportion fixed (47.6 % → 53.1 %)
 
-- The hero's colonnade (columns 2.00–7.95 + capitals 7.95–8.90) was 6.90 m of the
-  14.50 m elevation = **47.6 %**, below the photographed 50–60 %, because the
-  entablature (3.40 m) and parapet (2.20 m) used 5.60 m of the height.

-- **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

-  `preset_kwargs()` (bpy-free, unit-tested) plus `export_static()` /

-  construction.
-- Do not try to *measure* verticality from the rendered PNG with a naive edge

-  heights and the pairwise match is meaningless (it reported a 418 px "drift").

-  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

-  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.

-  `fbx_export_preset` plus a JSON part report (dims + evidence per piece).
-- `Tools/ue_import_facade_kit.py` → `/Game/Hollywood/Kit/*`, complex-as-simple

-- `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

 ## 2026-11-09 — kit naming + topology validation (blender-modeler checklist)
 
-- Kit assets now follow the Unreal convention: the Blender object keeps its readable

-  kit loader strips the `SM_` prefix so the layout code still addresses pieces by

-  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).

-  wrong-size fail); `--compare` measures luma, RMS contrast, edge density, palette

-  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

+- 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.

-- [ ] **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.
-- [x] **Define the façade module.** **Done 2026-11-09.** `Tools/facade_kit_build.py` builds the kit at the measured **4.96 m bay**: pilaster, sill, lintel, window bay (surround + inset glazing), shopfront bay (piers, glass, fascia), door bay (jambs, door, threshold), cornice and parapet + coping — 16 meshes, each exported through the shared `ue_metric_v1` preset with a JSON part report recording dims and evidence. `Tools/ue_import_facade_kit.py` imports to `/Game/Hollywood/Kit`. `Tools/ue_apply_facade_kit.py` assembles it from each building's own bounding box: **638 pieces placed across the six frontage buildings and both north buildings** (6922 = 13 bays × 11 storeys, theatre 8 × 5, TCL and Tussaud's 9 × 4, etc.). First pass put the window bays inside the solid wall (invisible) — the kit now projects the surround 3 cm proud with glazing 6 cm behind it.
-- [A] **Replace placeholder materials.** **In progress 2026-11-09.** `ensure_material()` now builds masonry coursing (world-space course height + joint band + tint, corrected for UE's centimetre WorldPosition) and roughness variation; new `M_FacadeStoneShadow`, `M_FacadeGlass` (specular 0.62 ≈ IOR 1.5 without a refraction pass) and `M_FacadeBanner`; assignment is per **slot** keyed on the imported slot name (it was slot-0 only, which on the hero is the banner, so stone/glass/shadow were still flat). Hero: 4/4 slots, frontage and north buildings 2/2. Remaining: bake real texture maps (brick/stone/asphalt generators) rather than graph-only detail, and give the frontage shopfront line its own material.
-- [x] **Give OSM buildings a façade style.** **Closed as superseded 2026-11-09.** The Blosm `setupScript` route would build a second, competing façade system next to the module kit defined in the previous task. The kit already gives every staged building a real elevation (shopfront line, window rhythm, pilasters, cornice, parapet) from a single module, so a Blosm style script would duplicate it with a different vocabulary and a different set of assumptions. Revisit only if the kit cannot express a building the photographs demand.
-- [ ] **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.
-- [A] **El Capitan Theatre (6838) and the retail neighbours.** **Theatre trim done 2026-11-09:** `Tools/theatre_trim_build.py` builds the features that make the building read as itself — 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 bracket; `Tools/ue_stage_theatre_trim.py` imports and stages it with site materials. Two bugs fixed en route: the trim was mirrored to the far side of the boulevard (Blender +Y is Unreal −Y) and the marquee sat 5 cm above the pavement (absolute Z where the pavement is 4.56 m above the datum). **Still open:** the retail neighbours modelled from the 18-frame reference set.

+- [ ] **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.
+- [ ] **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.
+- [ ] **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.
+- [ ] Tag `v0.1.5` and write `CHANGELOG.md` entry; then remove this section.
