release: v0.1.6 — retail frontage changelog entry, TODO pruning

Writes the 0.1.6 entry, removes the completed section from TODO.md (its goal stays
in ROADMAP.md per the convention), and updates the roadmap status line.

Release checks: 5/5 shots verify, scene audit 0 failures, 82 tool tests, LFS check
clean, owner approval recorded for the retail shot.

+| Description | "Lee Drug and 6806 Hollywood Buildings in Hollywood" |
+| Coverage | Both target buildings in one frame, mid-morning sun from the south-east |
+
+**One photograph is the whole evidence base for 6800 and 6806–6820.** It is a street-level oblique, not an elevation: verticals converge, the ground floor of 6806–6820 is partly behind a parked car, and the Lee Drug shopfront is behind a bus. Everything below that the photo does not resolve is marked _assumed_ and is carried into the part report.
+
+**6822 Budget has no photograph.** It is a 6.0 m × 5.5 m single-storey sliver west of 6806–6820, and the TODO item already records that Commons has nothing usable. It stays a blockout extrusion and the item is deferred rather than guessed.
+
+## Measured (not from the photo)
+
+From `Geo/raw/osm-api-map-2026-11-06.osm` and the blockout, in the shared frame (metres, X east, Y north, Z from the project datum):
+
+| Building | OSM way | X | Front face Y | Height | Depth |
+| --- | --- | --- | --- | --- | --- |
+| 6800 Lee Drug | 424024149 | −33.20 … −14.37 | −14.63 | 12.10 m | 33.5 m |
+| 6806–6820 | 424024150 | −66.08 … −33.07 | −12.52 | 12.10 m | 30.8 m |
+| 6822 Budget | 424024144 | −78.54 … −72.52 | −12.92 | 5.50 m | 15.4 m |
+
+Both target buildings are 12.10 m tall, which makes the _relative_ proportions in the photo directly usable: the parapet line, the cornice and the shopfront line can be read as fractions of the frame height.
+
+## 6800 Lee Drug — reading
+
+| Category | Observation |
+| --- | --- |
+| Subject | Corner retail block at Hollywood × Highland; the street face and the corner return are both visible |
+| Silhouette | Long low box, broken by a **rounded corner tower** that rises above the frontage parapet; the parapet is **stepped**, not flat |
+| Storeys | Two zones, not storeys: a tall shopfront zone and a single tall display wall above it |
+| Proportion (vertical) | Shopfront ≈ 0 → 0.36 H; bronze cornice ≈ 0.36 → 0.43 H; mural + lettering wall ≈ 0.43 → 0.82 H; stepped parapet ≈ 0.82 → 1.0 H (_assumed split; read off the frame, ±0.03 H_) |
+| Proportion (horizontal) | Corner tower occupies ≈ 4 m of the east end; eight mural panels at roughly 2.2 m centres along the frontage |
+| Colour | Cream stucco wall `#EDE6D8`, bronze/brown cornice `#6B4A2F`, near-black mural plates `#1C1A18`, dark glazing `#20262A` (_sampled from the frame_) |
+| Unique features | Stepped Deco parapet with 4 horizontal reveal lines; projecting bronze cornice; row of black celebrity-portrait panels; large dark "SOUVENIRS OF …" lettering on the upper wall; shopfront glazing with slim mullions |
+| Mood | 1930s Deco retail, freshly painted, bright midday |
+
+## 6806–6820 — reading
+
+| Category | Observation |
+| --- | --- |
+| Silhouette | Flat-fronted two-storey block; parapet steps up in fins at the west end |
+| Proportion (vertical) | Shopfront ≈ 0 → 0.32 H; burgundy fascia band ≈ 0.32 → 0.38 H; window storey ≈ 0.38 → 0.62 H; blank wall + parapet ≈ 0.62 → 1.0 H (_assumed_) |
+| Horizontal | Brown pilaster strips divide the frontage into roughly 3 m bays; seven upper windows across 33 m |
+| Colour | Same cream stucco; brown pilasters `#6B4A2F`; **burgundy-green** fascia `#5B3A3A`; white window frames |
+| Unique features | Banded parapet with 3 reveal lines; white-framed upper windows with security bars; shopfront glazing behind a burgundy fascia |
+
+## Camera match (for the review shot)
+
+The photo is a street-level oblique from the **north** side looking south-east, subject filling ~80 % of the frame width. The demo review shot must reproduce that: camera at 1.7 m on the north sidewalk, yaw toward the south frontage, 35–42° lens, both buildings in frame. A wide block view will not compare usefully against this crop.
+
+## Assumptions to carry into the model report
+
+1. Vertical proportions, as above — the photo's convergence makes a pixel-perfect read impossible.
+2. Mural panel size and spacing; the lettering is modelled as a recessed plate, not as text.
+3. Shopfront bay spacing on both buildings; the bus hides most of Lee Drug's ground floor.
+4. Parapet reveal line count (4 on Lee Drug, 3 on 6806–6820).
+5. Corner tower radius; only the outer curve is visible.

+## [0.1.6] — 2026-11-09
+
+Retail frontage. The two retail buildings beside the hero are modelled from their own photograph instead of the generic kit, and the photograph is treated as evidence: an analysis is written before any geometry, and every dimension the image does not resolve is carried into the part report as an assumption.
+
+### Added
+
+- **`Tools/retail_frontage_build.py`**: 6800 Lee Drug and 6806–6820 built from the one usable reference (`Art/reference/retail-neighbours/`, Gb321, CC BY-SA 4.0). Lee Drug gets a bronze cornice, storefront glazing with mullions, framed portrait panels, a painted lettering band, two-tier parapet with reveals and a fluted corner tower; 6806–6820 gets a burgundy fascia, brown pilasters, white-framed windows with security bars and its own banded parapet. Built in world coordinates from the blockout bounds (Lee Drug X −33.20…−14.37, face Y −14.63, H 12.10 m; 6806–6820 X −66.08…−33.07), joined to one mesh per building with a JSON part report.
+- **`Tools/ue_import_retail_detail.py`**: imports the two meshes with complex-as-simple collision — trim decorates a solid the player already collides with and must not add snag points.
+- **`Art/blender/retail/ref-analysis.md`**: the reference analysis the `references` skill pack requires, written before modelling.
+- **`Tools/_common.py`** and `Tools/tests/test_retail_frontage.py`: the bay-layout arithmetic, extracted so it is testable without Blender (4 tests).
+- **Review shot 5**, `demo/review-demo-retail-frontage`, embedded in `Screenshots/README.md`.
+
+### Changed
+
+- **The generic façade kit skips the two modelled buildings** (`MODELLED` list in `ue_apply_facade_kit.py`). It applies to every `Frontage_*`/`North_*` actor, so it was pasting a second, contradicting façade language over the new trim.
+- **Retail trim stages as `RetailTrim_*`** and is spawned through the demo builder, so it is regenerable rather than hand-placed.
+- Trim stucco, white and glass slots are mapped onto the demo's look-dev materials so the walls sit in the same noise and texture family as the rest of the block; the tones sampled from the photograph (bronze, burgundy, mural, lettering) stay as authored.
+
+### Fixed
+
+- **`Tools/render_screenshots.sh` never captured anything.** The capture step called `./Engine/...` while every commandlet above it went through `run_cmdlet`'s `cd "$ENGINE"`. Under `set -e` the script died at exit 127 _after_ rebuilding the maps, so the PNGs silently stayed a day old and `--verify` never ran.
+- **Duplicate `RetailTrim_*` actors on every rebuild**: the demo builder's clear list did not include the new label, so each run stacked another copy. Caught by the scene audit, not by eye.
+- **Mural plates were placed 0.20 m inside the solid blockout volume** and never rendered; the inset is now faked with a proud frame and a near-flush plate.
+- **Trim detail sat 0.05 m off the wall**, under a pixel of depth at 40 m, so the wall won the depth test. Trim planes now stand 0.10–0.20 m proud.
+- **6806–6820 parapet started at 0.62 H**, leaving a 4.6 m blank band; the window storey and parapet moved up to follow the photograph.
+- **Mural panels, parapet and lettering were sized from the photograph's proportions, not the inherited defaults**: the first pass left a parapet that read as one blank white band.
+
+### Verified
+
+- `render_screenshots.sh --verify`: **5/5 shots OK**; scene audit **0 failures** (every mesh materialed, all spans in tolerance, no duplicate labels).
+- Owner approved `demo-retail-frontage` (second pass) 2026-11-09; all five demo shots now carry approval.
+- 82 tool tests pass.
+
+### Known limitations
+
+- **Wall lettering and the painted band do not read at 40 m.** A plate at 0.10 m still vanishes; this is a decal/texture problem, not geometry. Moved to `0.9.0 — Realistic buildings`.
+- **The parapet has no moulded profile** and the corner tower is a fluted cylinder with two cap rings — both need the façade system in `0.9.0`.
+- **6822 Budget is untouched**: no photograph of it exists. Deferred and blocked in `0.9.0`.
+- The only reference for these two buildings is a single street-level oblique with a bus across Lee Drug's shopfront and a car across 6806's; several vertical proportions are assumptions recorded in the part report.
+
 ## [0.1.5] — 2026-11-09
 
 Façade finishing. The kit gets the hero detail it was missing, and a class of silent defect is found and gated: the map had been rendering with **604 of 620 mesh actors unmaterialed** without a single error.

+## ADR-8: Realistic building façades are a minor milestone, not a patch
+
+- **Context**: `0.1.4` carried the first façade pass as a _patch_, while the release policy says patches contain fixes and refinements and never new scope. The `0.1.6` retail pass then showed what that costs: a façade built in a patch has no release gate of its own, so a first pass that does not yet read as the building (`Screenshots/README.md`, 0.1.6 gaps) can sit inside a "done" patch series. Realism is also the project's leading quality goal, which a patch cannot carry.
+
+- **Decision**: Building realism gets its own minor milestone, `0.9.0 — Realistic buildings`, placed before the feature freeze. Its scope is the façade system (orders, profile library, storefront types, signage as decals), per-building photo-matched models, a measured material library with a texel-density rule, and LODs plus collision proxies. Patches keep fixes and refinements only. Renumbered by this decision: the former `0.9.0` freeze/beta/audit milestone becomes `0.10.0`, its patches `0.10.1`–`0.10.3`, and `1.0.0` moves to weeks 39–44.
+
+- **Consequences**: Façade work now has a release gate — every building measured against its own photograph, every building with a collision proxy and a LOD, no placeholder materials — so "modelled" means verified, not merely present. The price is that realism work stops being sliced into patches, and the schedule shifts by one minor cycle. Blockouts without a photograph stay blockouts and are listed as such, rather than being dressed up to fill the milestone.

-## 0.9.0 — Feature freeze, public beta, license and build audit (weeks 31–34)
+## 0.9.0 — Realistic buildings (weeks 31–34)
+
+**Goal:** every building in the demo area reads as the building it is, at walking distance, judged against its own photograph — and where no photograph exists it stays an honest blockout rather than an invented façade. This is the milestone that turns the façade system from "a kit applied to volumes" into architecture: a shared bay-and-profile vocabulary, a material library with measured albedo and roughness, modelled storefronts and signage, and per-building reference matching with a measured tolerance.
+
+**Scope:**
+
+- A façade system that carries more than one order: Art Deco, neoclassical and streamline-moderne variants on the same 4.96 m bay module, with a profile library for cornices, copings, string courses and storefront surrounds.
+- Per-building façades for the six south-side buildings and the two north-side buildings inside the 50 m buffer, each from its own reference set; the hero keeps its existing model and gains the detail levels this pass defines.
+- Storefronts and signage as first-class geometry plus decals: mullions, bulkheads, recessed entries, awning and canopy brackets, painted wall lettering, blade and projecting signs. Wall lettering is a texture/decal problem, not a block of geometry — the `0.1.6` attempt proved plates do not read.
+- A material library with measured values per surface type (stucco, painted render, ashlar, brick, terrazzo, glazing, bronze and steel trim) and a texel-density rule, replacing per-building ad-hoc colours.
+- LOD chain and collision proxies per building, so realism does not cost the 60 FPS floor.
+
+**Out of scope:** interiors, night lighting and audio (the `0.6.0` evening preset owns those), vehicles, pedestrians, and any change to footprints or massing — OSM stays the source for those.
+
+**Release gate:** each building has a review shot compared against its own photograph with the silhouette and proportion deltas recorded in `Screenshots/README.md`; no building carries an unverified façade; every building has a collision proxy and at least one LOD; 60 FPS at 1440p holds; no surface is left with a placeholder material; `THIRD_PARTY_NOTICES.md` covers every photographic reference used.
+
+## 0.10.0 — Feature freeze, public beta, license and build audit (weeks 35–38)
 
 **Goal:** freeze features, produce a public beta for testers, and complete the audits: licences for `THIRD_PARTY_NOTICES.md` and all MPFB, texture, animation, vehicle, and audio assets; Epic distribution requirements; and a fresh checkout that builds and packages reproducibly.

+
+Known gaps in this first pass, recorded rather than hidden:
+
+- **The parapet still reads as a blank band.** It is now two tiers with three deeper reveals, and the step is visible, but there is no profile or shadow line to break the wall — a moulded coping and a modelled reveal need the `0.9.0` façade system.
+- **The mural row now reads** (framed plates standing 0.12–0.20 m off the wall), but **the lettering band does not**: it is a plate at 0.10 m and it disappears at 40 m. Wall lettering is a decal/texture problem, scoped in `0.9.0`; no amount of extra plate depth fixed it in the second pass.
+- **The corner tower is a plain cylinder with two cap rings** — the stepped Deco profile in the photograph is richer than that.
+- **The camera crops the east end** of Lee Drug at 68° from the north sidewalk.
+- **6822 Budget is untouched** and still a bare blockout volume: no photograph of it exists.

 ## Known cosmetic issues
 
-- 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).
-- Banners sit on the column line rather than flush to the wall (they hang on the columns in the photographs, so this is acceptable).
-- Between kerb and building line the walkable surface is the terrain mesh, not a modelled pavement.
-- The El Capitan Theatre has no marquee or blade sign yet — the feature that makes it read as itself.
+Each issue is tracked in `TODO.md` under the version that will fix it; an issue with no ticket is a bug in the plan, not a note.

+
+### Façade system
+
+- [ ] **Extend the module kit beyond one order.** Art Deco, neoclassical and streamline-moderne variants on the shared 4.96 m bay: alternate window proportions, spandrel and transom bands, and the way each order terminates at the roof.
+- [ ] **Build a profile library** for cornices, copings, string courses, sills and storefront surrounds, so a building is assembled from named profiles rather than ad-hoc boxes.
+- [ ] **Storefront types**: recessed entry, bulkhead and kickplate, mullion spacing, transom, awning/canopy brackets, and grille/shutter variants.
+- [ ] **Signage and lettering as decals.** Painted wall lettering, blade signs and fascia panels become texture and decal work with a documented projection; `0.1.6` proved that lettering built as geometry plates cannot resolve at review distance.
+- [ ] Document the system in `Art/blender/README.md` and the arc42 building block view.
+
+### Per-building models
+
+Each building needs its own reference set; where none exists the blockout stays and the item says so.
+
+- [ ] Hero façade (6840): raise to this pass's detail level — capitals and fluting, window rhythm behind the colonnade, parapet motto band and medallions.
+- [ ] Hero façade (6840), entrance: **doors at street level left and right of the central bay**, as the photographs show, and correct positioning of the central-bay elements (column bases, entrance stairs, set-back entrance, door frames, banners and signage). Nothing may stand in front of the façade that blocks it — no awning, no temporary structure. Carried over from `Screenshots/README.md`, 2026-11-09.
+- [ ] El Capitan Theatre (6838): marquee, blade sign, entrance and the theatre's own elevation from its 18-frame set.
+- [ ] 6800 Lee Drug and 6806–6820: second pass on the `0.1.6` trim. Moved here from that patch because geometry cannot close them: **wall lettering as a decal** (a plate at 0.10 m still vanishes at 40 m), a **moulded parapet profile** instead of a two-tier box, richer **corner-tower stepping**, and the portrait panels reworked as textures rather than framed plates.
+- [ ] **Photography gap — 6822 Budget** (deferred out of `0.1.6`, blocked): no photograph exists; the single-storey 6.0 × 5.5 m volume cannot be read from the neighbour shot, so it stays a bare blockout until references are acquired. Record the sources checked in `Geo/`. Also re-shoot 6806–6820 and 6800 from the south sidewalk: the only reference is one oblique with a bus across Lee Drug's shopfront and a car across 6806's.
+- [ ] 6902, 6922 and the remaining south frontage.
+- [ ] North side: TCL Chinese Theatre and Madame Tussaud's façades from their reference sets.
+- [ ] Reconcile every modelled height against `Geo/tools/block_height_report.py` and record the source per building.
+
+### Materials, UVs and performance
+
+- [ ] **Measured material library**, including the hero's stone, which currently renders pale because it is a procedural graph and a generated texture set rather than a measured surface: stucco, painted render, ashlar, brick, terrazzo, glazing, bronze and steel trim, with albedo and roughness taken from the photographs rather than guessed; one Unreal material instance per surface type.
+- [ ] **Texel-density rule** per building class, applied through modular UVs; lightmap UVs where required.
+- [ ] **LOD chain and collision proxies** per building: UCX proxies for blocking volume, detail geometry non-colliding.
+- [ ] Re-validate the 60 FPS floor at 1440p once the detail lands, and record the cost of the pass.
+
+### Release checks
+
+- [ ] Every building with a photograph has a review shot measured against it, with silhouette and proportion deltas recorded in `Screenshots/README.md`.
+- [ ] No building carries an unverified façade; blockouts without references are listed as such in `TODO.md`.

+"""Retail frontage trim for 6800 Lee Drug and 6806–6820 (0.1.6).
+
+Both buildings are bare OSM extrusions with a flat stucco material; what makes them
+read as *the* retail run beside the hero is the façade layer: the bronze cornice and
+stepped Deco parapet on Lee Drug, and the pilaster-and-fascia rhythm on 6806–6820.
+
+The trim is built **in world coordinates** in the shared frame (metres, X east,
+Y north, Z from the project datum), so the export carries its position and the
+Unreal staging step is a single spawn at the origin — the same convention as
+`Tools/theatre_trim_build.py` and `Tools/export_block_frontage.py`.
+
+    blender -b --factory-startup --python Tools/retail_frontage_build.py -- \
+        --out /tmp/gigline/retail --report /tmp/gigline/retail-report.json
+
+Bounds are **measured**, not assumed: they are the blockout objects' world bounds
+(`Lee Drug Building`, `element.019`), which sit at Z 0 with the volume top at 12.10 m.
+Vertical proportions come from the single reference photograph and are recorded with
+the assumption in `Art/blender/retail/ref-analysis.md`.
+
+6822 Budget is deliberately **not** built: there is no photograph of it, and the TODO
+item says so. Guessing its façade would be the misattribution the item warns against.
