# TODO.md

Actionable task list for this project. This file is the single, central place for planned work, claims, and progress marks. Milestone goals, scope, and release gates are in [ROADMAP.md](ROADMAP.md).

## Conventions

- Mark items **open** (`- [ ]`), **active/in progress** (`- [A]`, **deferred** `- [D]`), or **done** (`- [x]`). Keep the marks accurate.
- A level-three (`###`) section being worked on carries `- active - <sessionId>` (and optionally the branch name) in its heading. Remove the suffix when you stop.
- When all steps in a version section are done: write a `CHANGELOG.md` entry, then remove the version section from this file.
- Release gate: a version is tagged only on the owner's explicit go-ahead once its release checks pass, not automatically when the checkboxes close.

## 0.1.2 — Scale and façade corrections (patch)

Suggested blender skills: **references** (reference-image-match and visual-match-checklist templates — measure the guessed heights and colonnade proportions against the photographs), **archviz** (real-world scale and façade composition discipline), **camera-cinematography** (reproduce the reference camera angles when comparing renders to photos).

### Patch tasks - active - 01a1b26b-3c94-707f-9665-2f6b4a79b564 (branch `scale-facade-0.1.2`)

- [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.
- [ ] 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. **Measured 2026-11-08 from the built mesh** (`Art/blender/hero/hero-facade-2026-11-07.blend`): envelope 0–14.50 m; stylobate 0–2.00; columns 2.00–7.95; capitals 7.95–8.90; entablature 8.90–12.30; parapet 12.30–14.50. So the colonnade (columns + capitals) is **6.90 m = 47.6 %** of the height — inside the range only at the low end. Bringing it to ~55 % needs ~+1.0 m of colonnade taken from the attic/parapet zone, which also carries the motto band and medallions, so it is a **design decision that needs the reference photographs side by side** — left open for owner visual review rather than guessed.
- [ ] Tag `v0.1.2` and write `CHANGELOG.md` entry; then remove this section.

## 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`.
- [ ] Update `Docs/` setup instructions for anything that changed.
- [ ] Tag `v0.1.3` and write `CHANGELOG.md` entry; then remove this section.

## 0.1.4 — Proper building façades (patch)

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.

## 0.2.0 — MPFB player body, third-person camera, basic animation (weeks 7–9)

### Character setup

- [x] Generate MPFB human base mesh; export baked materials and deform skeleton. Done in bootstrap: idle-pose 19 158-vert human with a 137-bone standard rig, `Tools/mpfb_character_export.py` (now `--pose idle` + warm `make_diffuse`).
- [x] Import character into Unreal; validate skeleton, scale, and materials. Done: `/Game/Test/Character` — `SkeletalMesh` (138 bones), `Skeleton`, warm `M_Character_Export` material with baked `T_Character_Diffuse`.
- [x] Promote the character asset into a reusable NPC prefab (visible body, collision capsule, idle pose) ready for pedestrians (`0.5.0`) once the third-person body lands. Done 2026-11-07: `AGigLineNPCPerson` (see the 0.1.0 Character-development item); `0.5.0` reuses it as the pedestrian base.
