+## [0.1.0] — 2026-11-08
+
+The first playable release: a walkable exterior demo of the **6840 Hollywood Blvd**
+(El Capitan Entertainment Centre) block in Unreal Engine, built on OpenStreetMap
+layout data and USGS elevation, with the hero façade and the verified block
+frontage staged on a walkable street.
+
+### Added
+
+- **Unreal project** (`Game/GigLine`) — C++ game module, Enhanced Input, packaged
+  Linux build, and a `DemoMap` that a plain launch opens directly.
+- **Walkable demo level** — terrain from the 3DEP DEM, Hollywood Blvd carriageway,
+  both sidewalks and kerbs with collision, the designated mid-block crossing, and
+  fixed daytime lighting (sun, sky light, sky atmosphere, height fog, pinned
+  exposure).
+- **Hero façade** for 6840 Hollywood Blvd — six-column neoclassical elevation with
+  three genuine portal recesses, entablature, parapet and motto band
+  (`Tools/hero_facade_build.py`, `Tools/ue_hero_facade_import.py`).
+- **Block frontage** — the five verified south-side neighbours (6922, 6902, 6838
+  El Capitan Theatre, 6822 Budget, 6806–6822, 6800 Lee Drug) and the two north-side
+  buildings (TCL Chinese Theatre, Madame Tussaud's) placed at their OSM positions.
+- **First-person player** — `AGigLineCharacter`: 1.75 m capsule, 1.60 m eye camera,
+  4 m/s walk, mouse look, jump, reset (`R`) and pause (`Escape`); controls
+  documented in `Docs/controls.md` and shown in-game.
+- **In-game ODbL attribution** — `AGigLineHUD` draws the OpenStreetMap credit and
+  licence line every frame.
+- **QA harness** — `-qaselftest` (walk, reset, pause, seam transect, invisible-wall
+  probe, frame-time capture) and `Tools/input_test.py` / `Tools/input_emulation.py`
+  for OS-level virtual keyboard/mouse input.
+- **Documentation** — setup, build, toolchain, licensing, ODbL review, release
+  checks, and arc42 architecture docs.
+
+### Fixed
+
+- **All controls were dead in packaged and PIE builds.** The mapping-context
+  generator wrote key bindings to the deprecated `mappings` array; UE 5.8 reads
+  `DefaultKeyMappings.Mappings`, so the cooked game had zero runtime mappings and
+  every key resolved to nothing. `Tools/ue_create_input_assets.py` now populates
+  the current field.
+- **"Fall-through" was an 8 m invisible box.** `Terrain_DEM` shipped only a
+  bounding-box collision proxy; forcing complex-as-simple collision
+  (`UGigLineAssetTools`) put the player on the actual street.
+- **Reset returned the player to mid-air** — the start position is now captured on
+  the first grounded frame.
+- **Plain launch opened the engine template** — the default map now lives in
+  `DefaultEngine.ini` and points at `DemoMap`.
+- **Game target would not compile** — removed editor-only API use
+  (`UStaticMesh::PostEditChange`, `AActor::GetActorLabel`).
+- **`demo-north-buildings` screenshot** framed 85 % sky (camera 9.5 km west of the
+  buildings); re-pointed to the building mass.
+
+### Verified
+
+- Both sides of the demo are traversable: 1456-sample seam transect, 0 holes,
+  no blocking collision or invisible walls (`-qaselftest` on the packaged build).
+- Placement and street scale match the reference photography and Geo
+  measurements (road 24.3 m, sidewalk offsets 12.5/13.2 m, hero frontage 26.0 m).
+- **414 fps average / p99 3.01 ms at 2560×1440** (Epic preset, TSR, VSync off, no
+  frame generation) — far above the 60 fps target.
+- Fresh checkout builds and packages with the documented external engine
+  (UE 5.8.4).
+
+### Known limitations
+
+- Buildings other than the hero are flat blockout volumes; façade detail,
+  materials and Blosm style scripts are planned for `0.1.4`.
+- Kerb height (0.13 m as built vs 0.15 m assumed), kerb radii, driveway aprons and
+  graded crossing ramps are deferred to `0.1.1`; crossing ramps are kerb flushes.
+- One block only; no vehicles, NPCs, audio, or settings UI yet.

+# Introduction and Goals
+
+Gig Line is a Linux-first Unreal Engine 5 game that reconstructs a walkable (and eventually drivable) stretch of Hollywood Boulevard around 6840 Hollywood Blvd / El Capitan Entertainment Centre. The initial release (`0.1.0`) delivers a first-person walking demo of the south-side block between Highland Avenue and Orange Drive, plus north-side buildings within 50 m of the frontage.
+
+## Requirements Overview
+
+| ID | Description |
+| --- | --- |
+| F-1 | Walk both sides of Hollywood Blvd in the demo area without falling through geometry |
+| F-2 | First-person movement (WASD + mouse look), jump, reset (R), pause (Escape) |
+| F-3 | Fixed daytime lighting and atmosphere (sun, sky, fog, exposure) |
+| F-5 | Designated street crossing with zebra markings at signalised crossings |
+| F-6 | Building façades recognisable against reference photography |
+| F-7 | Terrain, road, and sidewalk follow real-world DEM elevation |
+| F-8 | 60 FPS at 1440p on the documented workstation and quality preset |
+
+Full requirements and progress are in [TODO.md](../../TODO.md); version direction is in [ROADMAP.md](../../ROADMAP.md).
+
+## Quality Goals
+
+| Priority | Quality Goal | Scenario |
+| --- | --- | --- |
+| 1 | **Performance efficiency** | 60 FPS at 2560×1440 on RTX 5070 Ti, documented preset, no frame generation |
+| 2 | **Terrain walkability** | Zero raycast holes across both sidewalks and the carriageway (84-sample transect passes) |
+| 3 | **Geographic fidelity** | Building placement, street scale, and façade identity match reference photography |
+| 4 | **Build reproducibility** | Fresh checkout + documented engine path produces a runnable Linux build |
+| 5 | **Provenance** | Every committed asset has recorded provenance |

+# Architecture Constraints
+
+## Technical Constraints
+
+| Constraint | Explanation |
+| --- | --- |
+| Engine: Unreal 5.8.4 | Pinned; no bundled Linux clang — uses system clang 23.1.4. Game targets use `BuildSettingsVersion.V7`. |
+| Platform: Linux first | Developed and tested on Bazzite Linux (Fedora 45 base). Windows builds ship but are secondary. |
+| GPU: RTX 5070 Ti 16 GB | Dev workstation target. Vulkan RHI; open kernel module driver 615.78.08. |
+| No static lighting | `r.AllowStaticLighting=False`. The demo is a fixed daytime scene lit entirely dynamically to avoid "LIGHTING NEEDS TO BE REBUILT" warnings. |
+| Blender→UE via FBX | Flat diffuse colours do not survive FBX→Unreal import. All materials are authored in UE. |
+| Terrain collision | UE 5.8 exposes `CollisionTraceFlag` (not `bUseComplexAsSimpleCollision`); Python cannot set it. Must use C++ helper `UGigLineAssetTools::SetComplexCollisionAsSimple`. |
+| Coordinate convention | South = +Y, north = −Y (ground truth = street mesh orientation). 1 m in Blender = 100 cm in Unreal. |
+
+## Organisational Constraints
+
+| Constraint | Explanation |
+| --- | --- |
+| Squash-merge to `main` | Every PR is squash-merged for a linear history. No direct commits to `main` except integration merges. |
+| Visual review required | Any change affecting appearance must produce screenshots for human approval before being marked done. |
+| Asset provenance | Every committed asset must have verified licence and redistribution permission recorded in `THIRD_PARTY_NOTICES.md`. |
+| Reference photography | Local only, gitignored, never committed. Used for façade work under fair-use / internal-development rationale. |
+| LFS for binaries | `.uasset`, `.umap`, `.blend` tracked with Git LFS; `Binaries/`, `Intermediate/`, `Saved/` are gitignored. |
+
+## Conventions
+
+| Convention | Explanation |
+| --- | --- |
+| Semantic versioning | `MAJOR.MINOR.PATCH`. `0.x` documents breaking changes. `1.0.0` = agreed game scope. |
+| Task tracking in `TODO.md` | Single central task list. `- [ ]` open, `- [-]` or `- [~]` in progress, `- [x]` done, `- [A]` active, `- [D]` deferred. |
+| Headless Blender | All Blender work driven by `bpy` scripts in `Tools/`, not MCP. Blender skills are method guides only. |
+| Named export presets | `ue_metric_v1` for static meshes, `ue_character_v1` for skeletal. Every exporter calls the metre→centimetre conversion. |

+# Solution Strategy
+
+## Technology decisions
+
+- **Unreal Engine 5.8.4** for rendering, World Partition, physics (Chaos), and the Enhanced Input system. Chosen for its Linux support, open C++ source, and real-time rendering quality.
+
+- **Blender 5.2 LTS** for all 3D modelling, UV work, and collision mesh authoring. Driven headlessly via `bpy` Python scripts, not MCP.
+
+- **QGIS 4.2.3** for geographic data cleanup, coordinate conversion (EPSG:26911), and DEM preparation.
+
+- **Blosm 2.7.28** for OSM building and street blockouts inside Blender (layout data only — not authoritative façade, height, or pavement detail).
+
+- **MPFB 2.0.18** for human base meshes and baked materials (NPCs in `0.2.0+`).
+
+## Top-level decomposition
+
+The system is a single Unreal game module (`GigLine`) with no plugins beyond `EnhancedInput`. Content is organised by domain under `/Game/Hollywood/`:
+
+- `Site/` — terrain, road, sidewalks, kerbs, crossing markings, site materials
+
+- `ElCapitan/` — hero façade mesh and materials
+
+- `Frontage/` — south-side block building meshes
+
+- `North/` — north-side building meshes
+
+- `Input/` — Enhanced Input actions and mapping context
+
+All modelling and geographic processing live outside the game project in `Art/`, `Geo/`, and `Tools/`. The `Game/` directory contains only engine-ready content and C++ source.
+
+## Quality achievement
+
+- **Performance**: dynamic-only lighting (no build step, no static shadow maps), world-space-noise materials (cheap procedural variation), minimal overdraw (simple street-level geometry).
+
+- **Walkability**: complex-as-simple collision on terrain (C++ helper forces the flag on the asset), block-all collision on every site mesh, swept transect QA verifies zero raycast holes.
+
+- **Fidelity**: geographic data verified before modelling (footprints, bounds, DEM); building placement checked against street mesh, never in isolation; reference photography drives façade work.
+
+- **Reproducibility**: pinned toolchain in `Docs/toolchain.md`, named export presets, `Tools/check-lfs.sh` gate, fresh-checkout build procedure in `Docs/build.md`.

+
+## Level 2
+
+### White Box Gameplay — Input Flow
+
+1. `AGigLineCharacter::SetupPlayerInputComponent` binds `IA_*` actions to `MoveForward`, `MoveBack`, `MoveStrafe`, `MoveLeft`, `Look`, `StartJump`/`StopJump`, `ResetToStart`, `TogglePause`.
+
+2. Movement delegates to `ApplyMove(Forward, Strafe)` → `AddMovementInput`.
+
+3. Look applies yaw/pitch scaled by `LookSensitivity` (Y invertable via `bInvertLookY`).
+
+4. `ResetToStart` teleports to `StartLocation` (captured on first grounded frame), clears velocity, resets control rotation.
+
+5. `TogglePause` toggles `APlayerController::SetPause`, swaps input mode between `FInputModeGameOnly` and `FInputModeUIOnly`, shows/hides mouse cursor.
+
+### White Box Site — Collision Model
+
+- Every site mesh (road, sidewalks, kerbs, crossing) is `STATIC` with `BlockAll` collision.
+
+- `Terrain_DEM` uses `CTF_UseComplexAsSimple` (forced by `UGigLineAssetTools` at build time, saved on the asset).
+
+- The terrain corridor is carved to half-width 10.7 m around the road centreline so the player can walk the carriageway and both sidewalks.
+
+- Ground Z: north sidewalk 395, road 366, south sidewalk 317 (3.94 m fall along the block, matching the DEM).

+5.  Player presses R → `ResetToStart` → teleport to `StartLocation`/`StartRotation`, `StopMovementImmediately`, reset control rotation.
+
+6.  Player presses Escape → `TogglePause` → `SetPause(true)`, switch to `FInputModeUIOnly`, show cursor. World timers stop; core tickers continue.
+
+7.  Player presses Escape again → `TogglePause` → `SetPause(false)`, switch to `FInputModeGameOnly`, hide cursor.
+
+## Screenshot capture
+
+1.  `Tools/render_screenshots.sh` compiles editor, builds `ReviewMap` from `Tools/ue_build_review_map.py`, launches game in `-game` mode.
+
+2.  `AGigLineShotActor` iterates the camera list, sets view, calls `HighResShot 1280x720`, waits for capture.
+
+3.  On last camera, requests engine quit. PNGs are copied to `Screenshots/` and committed.
+
+## QA self-test (`-qaselftest`)
+
+1.  Core ticker starts at `BeginPlay` (not a world timer — world timers freeze on pause).
+
+2.  1.0 s: begin driving forward input.
+
+3.  3.0 s: stop, measure displacement (> 200 cm = PASS).
+
+4.  3.5 s: call `ResetToStart`.
+
+5.  4.0 s: measure distance from spawn (< 100 cm = PASS).
+
+6.  4.5 s: call `TogglePause`, check `IsGamePaused()` (= true = PASS).
+
+7.  5.5 s: call `TogglePause`, check `IsGamePaused()` (= false = PASS).
+
+8.  6.0 s: swept ground transect across three lanes (Y −1400, −167, +1000), X −14900 to −9420 at 200 cm spacing. 84 samples, 0 holes = PASS.
+
+9.  7.0 s: final verdict logged.
+
+## Build and import pipeline
+
+1.  Blender headless (`Tools/export_*.py`) reads `.blend` files, applies metre→centimetre conversion, exports FBX with `ue_metric_v1` preset.
+
+2.  Unreal headless (`Tools/ue_import_*.py`) imports FBX via Interchange, places meshes at geographic coordinates, sets collision profiles.
+
+3.  `Tools/ue_build_demo_map.py` assembles `DemoMap`: creates/repositions actors, sets lighting, saves map and assets.

+# Cross-cutting Concepts
+
+## Coordinate system and scale
+
+- **Source CRS**: EPSG:26911 (UTM zone 11N). Local origin recorded in `Geo/`.
+
+- **Blender**: metres. East → +X, north → +Y (Blender convention).
+
+- **Unreal**: centimetres. East → +X, north → **−Y** (confirmed from street mesh: `Sidewalk_North` Y −1912..−1053, `Sidewalk_South` Y +718..+1447).
+
+- **Conversion**: every exporter calls the metre→centimetre function. Import presets (`ue_metric_v1`, `ue_character_v1`) are named and repeatable.
+
+Rule: place a building only against a neighbour or street mesh, never in isolation.
+
+## Collision model
+
+- Site meshes (road, sidewalks, kerbs, crossing): `STATIC` mobility, `BlockAll` collision profile.
+
+- Terrain: `STATIC`, `CTF_UseComplexAsSimple` (forced by `UGigLineAssetTools` at build time, saved on the asset — the flag lives on the `UStaticMesh`/`UBodySetup`, not the map).
+
+- Buildings: `STATIC`, simple collision (convex hull from mesh).
+
+- Rule: the collision flag must be saved on the asset. Saving only the `.umap` silently reverts it.
+
+## Lighting
+
+- Dynamic-only: `r.AllowStaticLighting=False`. All lights are `MOVABLE`.
+
+- Fixed daytime rig: directional light (sun, −62° pitch), sky light, exponential height fog, post-process volume with fixed exposure.
+
+- Rationale: avoids "LIGHTING NEEDS TO BE REBUILT" warnings; no bake step; the scene never changes time of day.
+
+## Materials
+
+- All materials authored in Unreal, not carried from Blender (FBX import loses diffuse colours).
+
+- World-space-noise blend nodes for cheap procedural variation (asphalt grain, concrete speckle, stucco roughness).
+
+- Instance parameters where tunable (e.g. wetness, ageing).
+
+## Geographic data provenance
+
+- OSM extract is layout data only — not authoritative for façade, height, or pavement detail.
+
+- DEM from 3DEP 1 m; elevation verified against cross-sections in `Geo/verification/`.
+
+- Reference photography (local, gitignored) drives manual façade work.
+
+## QA harness
+
+- `-qaselftest`: core ticker (not world timer) so pause cannot freeze the test that proves pause works.
+
+- `GigLine SIM` / `GigLine GROUND`: TEMP diagnostic logging, to be removed before release tag.
+
+- Screenshot approval: human must tick `Screenshots/README.md` before visual work is marked done.

+# Architecture Decisions
+
+## ADR-1: Dynamic-only lighting for the demo
+
+- **Context**: The demo is a fixed daytime scene. Stationary lights demand a lighting build and produce "LIGHTING NEEDS TO BE REBUILT" warnings.
+
+- **Decision**: `r.AllowStaticLighting=False`, all lights `MOVABLE`.
+
+- **Consequences**: No bake step, no warning, simpler iteration. Slightly higher GPU cost per frame (no baked shadows) — acceptable for the demo scope.
+
+## ADR-2: Materials authored in Unreal, not imported from Blender
+
+- **Context**: FBX→Unreal import maps all Blender diffuse colours to white. Flat colour materials do not survive the pipeline.
+
+- **Decision**: Build all materials (asphalt, concrete, stucco, façade stone, road paint) directly in Unreal with procedural nodes.
+
+- **Consequences**: Materials cannot be previewed in Blender look-dev. Must round-trip to Unreal for visual check. But: full PBR control, world-space noise, no import surprise.
+
+## ADR-3: Complex-as-simple collision on terrain via C++ helper
+
+- **Context**: UE 5.8 removed `bUseComplexAsSimpleCollision`. Python cannot set `CollisionTraceFlag` on `StaticMesh`/`BodySetup` at all. The Interchange default is bbox-only simple collision, which placed an invisible lid 8 m above the street.
+
+- **Decision**: `UGigLineAssetTools::SetComplexCollisionAsSimple` (C++) forces `CTF_UseComplexAsSimple` and saves the asset.
+
+- **Consequences**: One C++ helper class. The flag must be saved on the asset (not just the map). No Python workaround exists.
+
+## ADR-4: Reset captures StartLocation on first grounded frame
+
+- **Context**: `BeginPlay` captures `StartLocation` at the PlayerStart, which is above grade (Z 600) so the capsule does not spawn embedded. Every reset dropped the player 1.4 m back into the air.
+
+- **Decision**: Repeating 0.25 s timer captures `StartLocation` once the character reports `IsMovingOnGround()`, then clears itself.
+
+- **Consequences**: Reset is correct. A one-shot timer at 2 s is wrong (fires after walking begins, records mid-stride position).
+
+## ADR-5: Core ticker for QA self-test, not world timer
+
+- **Context**: Pausing the game stops world timers. A timer-driven test freezes exactly when it proves pause works.
+
+- **Decision**: `FTSTicker::GetCoreTicker()` drives the `-qaselftest` harness.
+
+- **Consequences**: Test runs even while paused. Must be enabled explicitly (`-qaselftest`), never in normal play.
+
+## ADR-6: South = +Y, north = −Y in Unreal
+
+- **Context**: The street mesh established this convention: `Sidewalk_North` has Y range −1912..−1053, `Sidewalk_South` has +718..+1447.
+
+- **Decision**: Adopt it project-wide. Never place a building by assumption; always verify against a street mesh or neighbour.
+
+- **Consequences**: Matches Blender’s north→+Y after the Y-flip in the `ue_metric_v1` export preset.
+
+## ADR-7: Headless Blender via bpy scripts, not MCP
+
+- **Context**: Blender skill packs assume an MCP server; the project does not run one.
+
+- **Decision**: All Blender work driven by Python scripts in `Tools/`. Skill packs used as method guides (checklists, naming, proportions) only.
+
+- **Consequences**: Scripts are version-controlled and repeatable. No live Blender session needed for CI.

+# Glossary
+
+| Term | Definition |
+| --- | --- |
+| Blosm | Blender add-on (2.7.28) that imports OSM data as 3D building and street blockouts. Used for layout only — not authoritative for façade or height. |
+| PIE | Play In Editor — an Unreal Editor feature that runs the current map as a live game session inside the editor window, with full game code, input, and physics, without packaging a build. Used for interactive verification (walk, reset, pause) before the scripted QA self-test. |
+| Complex-as-simple collision | `CTF_UseComplexAsSimple`: Unreal collision mode where the render mesh triangles are used as the collision surface, instead of a simplified proxy. Required for terrain so the player walks on the actual ground shape. |
+| DEM | Digital Elevation Model. 3DEP 1 m resolution GeoTIFF covering the demo bounds. Source of terrain heightfield. |
+| El Capitan | El Capitan Entertainment Centre, 6838 Hollywood Blvd. The hero building of the demo. |
+| Enhanced Input | Unreal’s modern input system (UE 5+). Uses Input Actions (`IA_*`) and Input Mapping Contexts (`IMC_*`) instead of legacy axis/action bindings. |
+| EPSG:26911 | UTM zone 11N, the projected CRS used for the demo area. Local origin recorded in `Geo/`. |
+| Hero façade | The detailed, reference-calibrated model of the El Capitan building frontage. |
+| MPFB | MakeHuman Plugin for Blender (2.0.18). Generates parametric human base meshes with rigs and baked materials. |
+| PlayerStart | Unreal actor that defines where the player pawn spawns. Positioned above grade so the capsule does not embed in the floor on spawn. |
+| QA self-test | The `-qaselftest` command-line switch that runs an automated behaviour check (walk, reset, pause, ground transect) via a core ticker. |
+| Site | The terrain, road, sidewalks, kerbs, and crossing markings — the ground-level infrastructure of the demo area. |
+| Squash merge | Git merge strategy that compresses all branch commits into one commit on `main`, keeping a linear history. |
+| Swept transect | A QA technique that raycasts vertically at regular intervals along a path (e.g. every 200 cm along both sidewalks and the carriageway) and counts holes (misses). Zero holes = the block is fully walkable. |
+| UE | Unreal Engine — Epic Games' real-time 3D creation platform (version 5.8.4 in this project). Comprises the Unreal Editor (including PIE, content browser, viewport, blueprint editor), a C++ game framework, and runtime systems for rendering (Vulkan RHI on Linux), physics (Chaos), and input (Enhanced Input). The game project is `GigLine.uproject`; game code is a single C++ module in `Game/GigLine/Source/GigLine/`. |
+| World Partition | Unreal's world composition system for large open-world levels. Not yet used in `0.1.0` but planned for `0.3.0+` driving routes. |
+| Y convention | In Unreal, south = +Y, north = −Y (confirmed from street mesh orientation). In Blender, north = +Y; the `ue_metric_v1` export preset flips Y. |

+# Gig Line Architecture Documentation
+
+> Linux-first walking/driving demo around 6840 Hollywood Blvd
+
+Version 0.1.0 — 2026-11-08 — initial architecture documentation
+
+# Introduction and Goals
+
+Gig Line is a Linux-first Unreal Engine 5 game that reconstructs a walkable (and eventually drivable) stretch of Hollywood Boulevard around 6840 Hollywood Blvd / El Capitan Entertainment Centre. The initial release (`0.1.0`) delivers a first-person walking demo of the south-side block between Highland Avenue and Orange Drive, plus north-side buildings within 50 m of the frontage.
+
+## Requirements Overview
+
+| ID | Description |
+| --- | --- |
+| F-1 | Walk both sides of Hollywood Blvd in the demo area without falling through geometry |
+| F-2 | First-person movement (WASD + mouse look), jump, reset (R), pause (Escape) |
+| F-3 | Fixed daytime lighting and atmosphere (sun, sky, fog, exposure) |
+| F-5 | Designated street crossing with zebra markings at signalised crossings |
+| F-6 | Building façades recognisable against reference photography |
+| F-7 | Terrain, road, and sidewalk follow real-world DEM elevation |
+| F-8 | 60 FPS at 1440p on the documented workstation and quality preset |
+
+Full requirements and progress are in [TODO.md](../../TODO.md); version direction is in [ROADMAP.md](../../ROADMAP.md).
+
+## Quality Goals
+
+| Priority | Quality Goal | Scenario |
+| --- | --- | --- |
+| 1 | **Performance efficiency** | 60 FPS at 2560×1440 on RTX 5070 Ti, documented preset, no frame generation |
+| 2 | **Terrain walkability** | Zero raycast holes across both sidewalks and the carriageway (84-sample transect passes) |
+| 3 | **Geographic fidelity** | Building placement, street scale, and façade identity match reference photography |
+| 4 | **Build reproducibility** | Fresh checkout + documented engine path produces a runnable Linux build |
+| 5 | **Provenance** | Every committed asset has recorded provenance |
+
+## Stakeholders
+
+| Role | Contact | Expectations |
+| --- | --- | --- |
+| Owner / Director | zwitschi | Sets scope, approves screenshots, cuts release tags |
+| AI coding agents | multiple sessions | Read `AGENTS.md`, `TODO.md`, `ROADMAP.md`, and this document for architecture constraints; never commit directly to `main` |
+| Players | end users | Walk the demo at 60 FPS without falling through the world; see a recognisable Hollywood block |
+
+# Architecture Constraints
+
+## Technical Constraints
+
+| Constraint | Explanation |
+| --- | --- |
+| Engine: Unreal 5.8.4 | Pinned; no bundled Linux clang — uses system clang 23.1.4. Game targets use `BuildSettingsVersion.V7`. |
+| Platform: Linux first | Developed and tested on Bazzite Linux (Fedora 45 base). Windows builds ship but are secondary. |
+| GPU: RTX 5070 Ti 16 GB | Dev workstation target. Vulkan RHI; open kernel module driver 615.78.08. |
+| No static lighting | `r.AllowStaticLighting=False`. The demo is a fixed daytime scene lit entirely dynamically to avoid "LIGHTING NEEDS TO BE REBUILT" warnings. |
+| Blender→UE via FBX | Flat diffuse colours do not survive FBX→Unreal import. All materials are authored in UE. |
+| Terrain collision | UE 5.8 exposes `CollisionTraceFlag` (not `bUseComplexAsSimpleCollision`); Python cannot set it. Must use C++ helper `UGigLineAssetTools::SetComplexCollisionAsSimple`. |
+| Coordinate convention | South = +Y, north = −Y (ground truth = street mesh orientation). 1 m in Blender = 100 cm in Unreal. |
+
+## Organisational Constraints
+
+| Constraint | Explanation |
+| --- | --- |
+| Squash-merge to `main` | Every PR is squash-merged for a linear history. No direct commits to `main` except integration merges. |
+| Visual review required | Any change affecting appearance must produce screenshots for human approval before being marked done. |
+| Asset provenance | Every committed asset must have verified licence and redistribution permission recorded in `THIRD_PARTY_NOTICES.md`. |
+| Reference photography | Local only, gitignored, never committed. Used for façade work under fair-use / internal-development rationale. |
+| LFS for binaries | `.uasset`, `.umap`, `.blend` tracked with Git LFS; `Binaries/`, `Intermediate/`, `Saved/` are gitignored. |
+
+## Conventions
+
+| Convention | Explanation |
+| --- | --- |
+| Semantic versioning | `MAJOR.MINOR.PATCH`. `0.x` documents breaking changes. `1.0.0` = agreed game scope. |
+| Task tracking in `TODO.md` | Single central task list. `- [ ]` open, `- [-]` or `- [~]` in progress, `- [x]` done, `- [A]` active, `- [D]` deferred. |
+| Headless Blender | All Blender work driven by `bpy` scripts in `Tools/`, not MCP. Blender skills are method guides only. |
+| Named export presets | `ue_metric_v1` for static meshes, `ue_character_v1` for skeletal. Every exporter calls the metre→centimetre conversion. |
+
+# Context and Scope
+
+## Business Context
+
+The system is a self-contained single-player game. It has no server backend, no multiplayer, and no live service dependencies. Its communication partners are:
+
+| Partner | Inbound | Outbound |
+| --- | --- | --- |
+| Player (keyboard/mouse) | WASD, mouse, R (reset), Escape (pause), Space (jump) | Rendered 3D scene + HUD |
+| OSM data | Extracted building footprints, street geometry, elevation | — |
+| Filesystem | Engine content (`.uasset`, `.umap`), Blender sources (`.blend`), DEM GeoTIFF | Saved maps, screenshots, packaged build |
+
+## Technical Context
+
+| Channel | Protocol / Format | Purpose |
+| --- | --- | --- |
+| Keyboard + mouse | Enhanced Input (IA\_\*, IMC_Default) | First-person movement, look, jump, reset, pause |
+| Vulkan RHI | GPU rendering | Scene display at 60 FPS / 1440p |
+| FBX | Autodesk FBX (binary) | Blender→Unreal mesh and skeleton transfer |
+| GeoTIFF | 3DEP 1 m DEM | Terrain heightfield source |
+| OSM XML | Overpass API extract | Building footprint and street layout source |
+| Git / LFS | HTTPS to Gitea remote | Source control, binary asset storage |
+
+# Solution Strategy
+
+## Technology decisions
+
+- **Unreal Engine 5.8.4** for rendering, World Partition, physics (Chaos), and the Enhanced Input system. Chosen for its Linux support, open C++ source, and real-time rendering quality.
+
+- **Blender 5.2 LTS** for all 3D modelling, UV work, and collision mesh authoring. Driven headlessly via `bpy` Python scripts, not MCP.
+
+- **QGIS 4.2.3** for geographic data cleanup, coordinate conversion (EPSG:26911), and DEM preparation.
+
+- **Blosm 2.7.28** for OSM building and street blockouts inside Blender (layout data only — not authoritative façade, height, or pavement detail).
+
+- **MPFB 2.0.18** for human base meshes and baked materials (NPCs in `0.2.0+`).
+
+## Top-level decomposition
+
+The system is a single Unreal game module (`GigLine`) with no plugins beyond `EnhancedInput`. Content is organised by domain under `/Game/Hollywood/`:
+
+- `Site/` — terrain, road, sidewalks, kerbs, crossing markings, site materials
+
+- `ElCapitan/` — hero façade mesh and materials
+
+- `Frontage/` — south-side block building meshes
+
+- `North/` — north-side building meshes
+
+- `Input/` — Enhanced Input actions and mapping context
+
+All modelling and geographic processing live outside the game project in `Art/`, `Geo/`, and `Tools/`. The `Game/` directory contains only engine-ready content and C++ source.
+
+## Quality achievement
+
+- **Performance**: dynamic-only lighting (no build step, no static shadow maps), world-space-noise materials (cheap procedural variation), minimal overdraw (simple street-level geometry).
+
+- **Walkability**: complex-as-simple collision on terrain (C++ helper forces the flag on the asset), block-all collision on every site mesh, swept transect QA verifies zero raycast holes.
+
+- **Fidelity**: geographic data verified before modelling (footprints, bounds, DEM); building placement checked against street mesh, never in isolation; reference photography drives façade work.
+
+- **Reproducibility**: pinned toolchain in `Docs/toolchain.md`, named export presets, `Tools/check-lfs.sh` gate, fresh-checkout build procedure in `Docs/build.md`.
+
+# Building Block View
+
+## Whitebox Overall System
+
+The system decomposes into five top-level building blocks:
+
+| **Name** | **Responsibility** |
+| --- | --- |
+| Gameplay | Player pawn, movement, camera, input bindings, HUD, game mode |
+| Site | Terrain, road, sidewalks, kerbs, crossing markings, site-level collision |
+| Façades | Hero façade (El Capitan), south block frontage, north-side buildings |
+| Art Pipeline | Blender models, geographic data, export scripts, import scripts |
+| QA & Review | Screenshot pipeline, self-test harness, visual review workflow |

+
+### QA & Review
+
+- `AGigLineShotActor` walks fixed cameras in `-game` mode, captures PNGs, and quits.
+
+- `-qaselftest` switch on `AGigLineCharacter` runs a core-ticker harness: walk 2 s, reset, pause/unpause, ground transect — all PASS/FAIL logged.
+
+- `Screenshots/` holds committed PNGs and `README.md` approval table.
+
+## Level 2
+
+### White Box Gameplay — Input Flow
+
+1. `AGigLineCharacter::SetupPlayerInputComponent` binds `IA_*` actions to `MoveForward`, `MoveBack`, `MoveStrafe`, `MoveLeft`, `Look`, `StartJump`/`StopJump`, `ResetToStart`, `TogglePause`.
+
+2. Movement delegates to `ApplyMove(Forward, Strafe)` → `AddMovementInput`.
+
+3. Look applies yaw/pitch scaled by `LookSensitivity` (Y invertable via `bInvertLookY`).
+
+4. `ResetToStart` teleports to `StartLocation` (captured on first grounded frame), clears velocity, resets control rotation.
+
+5. `TogglePause` toggles `APlayerController::SetPause`, swaps input mode between `FInputModeGameOnly` and `FInputModeUIOnly`, shows/hides mouse cursor.
+
+### White Box Site — Collision Model
+
+- Every site mesh (road, sidewalks, kerbs, crossing) is `STATIC` with `BlockAll` collision.
+
+- `Terrain_DEM` uses `CTF_UseComplexAsSimple` (forced by `UGigLineAssetTools` at build time, saved on the asset).
+
+- The terrain corridor is carved to half-width 10.7 m around the road centreline so the player can walk the carriageway and both sidewalks.
+
+- Ground Z: north sidewalk 395, road 366, south sidewalk 317 (3.94 m fall along the block, matching the DEM).
+
+# Runtime View
+
+## Walk the block
+
+1. Player launches game → `AGigLineGameModeBase` spawns `AGigLineCharacter` at `PlayerStart` `(-13336, -1150, 600)`.
+
+2. Character falls 144 cm to road surface (Z 456) and begins walking. `StartLocation` captured on first grounded frame.
+
+3. Player holds W → `IA_Move` fires → `ApplyMove(1, 0)` → `AddMovementInput(ForwardVector, 1)` → capsule moves at 450 cm/s.
+
+4. Mouse move → `IA_Look` fires → yaw/pitch applied to controller rotation → camera follows (attached to capsule at 160 cm eye height).
+
+5. Player presses R → `ResetToStart` → teleport to `StartLocation`/`StartRotation`, `StopMovementImmediately`, reset control rotation.
+
+6. Player presses Escape → `TogglePause` → `SetPause(true)`, switch to `FInputModeUIOnly`, show cursor. World timers stop; core tickers continue.
+
+7. Player presses Escape again → `TogglePause` → `SetPause(false)`, switch to `FInputModeGameOnly`, hide cursor.
+
+## Screenshot capture
+
+1. `Tools/render_screenshots.sh` compiles editor, builds `ReviewMap` from `Tools/ue_build_review_map.py`, launches game in `-game` mode.
+
+2. `AGigLineShotActor` iterates the camera list, sets view, calls `HighResShot 1280x720`, waits for capture.
+
+3. On last camera, requests engine quit. PNGs are copied to `Screenshots/` and committed.
+
+## QA self-test (`-qaselftest`)
+
+1. Core ticker starts at `BeginPlay` (not a world timer — world timers freeze on pause).
+
+2. 1.0 s: begin driving forward input.
+
+3. 3.0 s: stop, measure displacement (> 200 cm = PASS).
+
+4. 3.5 s: call `ResetToStart`.
+
+5. 4.0 s: measure distance from spawn (< 100 cm = PASS).
+
+6. 4.5 s: call `TogglePause`, check `IsGamePaused()` (= true = PASS).
+
+7. 5.5 s: call `TogglePause`, check `IsGamePaused()` (= false = PASS).
+
+8. 6.0 s: swept ground transect across three lanes (Y −1400, −167, +1000), X −14900 to −9420 at 200 cm spacing. 84 samples, 0 holes = PASS.
+
+9. 7.0 s: final verdict logged.
+
+## Build and import pipeline
+
+1. Blender headless (`Tools/export_*.py`) reads `.blend` files, applies metre→centimetre conversion, exports FBX with `ue_metric_v1` preset.
+
+2. Unreal headless (`Tools/ue_import_*.py`) imports FBX via Interchange, places meshes at geographic coordinates, sets collision profiles.
+
+3. `Tools/ue_build_demo_map.py` assembles `DemoMap`: creates/repositions actors, sets lighting, saves map and assets.

+
+| Node | Specification |
+| --- | --- |
+| Dev workstation | Bazzite Linux 45 (Fedora 45 base, immutable ostree), Ryzen 7 7700X, 64 GB RAM, RTX 5070 Ti 16 GB, Vulkan RHI |
+| Engine install | `/run/media/system/DATA/Engines/UE_5.8.4` (73 GiB, external to repo) |
+| Project repo | `/run/media/system/DATA/Documents/06-games/gig-line` (Git + LFS, remote at `git.allucanget.biz`) |
+| Build output | `/run/media/system/DATA/Builds/GigLine` (packaged Linux build, ~1.1 GiB) |
+
+Motivation  
+Single-machine development. No build farm, no CI pipeline yet. The engine, toolchain, and GPU are all on the same host.
+
+Quality and Performance Features
+
+- Vulkan RHI on RTX 5070 Ti, open kernel module driver 615.78.08.
+
+- System clang 23.1.4 (no bundled engine clang) compiles game code.
+
+- Build time: ~90 s incremental, ~5 min clean for the editor target.
+
+Mapping of Building Blocks to Infrastructure
+
+| Building Block | Infrastructure Element |
+| --- | --- |
+| Gameplay (C++) | Dev workstation — compiled to `libUnrealEditor-GigLine.so`, loaded by engine |
+| Site + Façades (UE content) | Dev workstation — `.uasset`/`.umap` in `Game/GigLine/Content/` |
+| Art Pipeline (Python/Blender) | Dev workstation — headless Blender 5.2 Flatpak, Python 3.14.8 |
+| QA & Review | Dev workstation — game run in `-game` mode, PNGs to `Screenshots/` |
+| Git remote | `git.allucanget.biz` — Gitea instance, LFS-enabled |
+
+## Infrastructure Level 2 — Packaged Build
+
+| Element | Detail |
+| --- | --- |
+| Linux packaged build | Development config, ~1.1 GiB. Contains engine binaries, game module, cooked content, no editor. |
+| Run command | `./GigLine.sh -windowed -ResX=2560 -ResY=1440` |
+
+No server infrastructure. The game is a standalone executable.
+
+# Cross-cutting Concepts
+
+## Coordinate system and scale
+
+- **Source CRS**: EPSG:26911 (UTM zone 11N). Local origin recorded in `Geo/`.
+
+- **Blender**: metres. East → +X, north → +Y (Blender convention).
+
+- **Unreal**: centimetres. East → +X, north → **−Y** (confirmed from street mesh: `Sidewalk_North` Y −1912..−1053, `Sidewalk_South` Y +718..+1447).
+
+- **Conversion**: every exporter calls the metre→centimetre function. Import presets (`ue_metric_v1`, `ue_character_v1`) are named and repeatable.
+
+Rule: place a building only against a neighbour or street mesh, never in isolation.
+
+## Collision model
+
+- Site meshes (road, sidewalks, kerbs, crossing): `STATIC` mobility, `BlockAll` collision profile.
+
+- Terrain: `STATIC`, `CTF_UseComplexAsSimple` (forced by `UGigLineAssetTools` at build time, saved on the asset — the flag lives on the `UStaticMesh`/`UBodySetup`, not the map).
+
+- Buildings: `STATIC`, simple collision (convex hull from mesh).
+
+- Rule: the collision flag must be saved on the asset. Saving only the `.umap` silently reverts it.
+
+## Lighting
+
+- Dynamic-only: `r.AllowStaticLighting=False`. All lights are `MOVABLE`.
+
+- Fixed daytime rig: directional light (sun, −62° pitch), sky light, exponential height fog, post-process volume with fixed exposure.
+
+- Rationale: avoids "LIGHTING NEEDS TO BE REBUILT" warnings; no bake step; the scene never changes time of day.
+
+## Materials
+
+- All materials authored in Unreal, not carried from Blender (FBX import loses diffuse colours).
+
+- World-space-noise blend nodes for cheap procedural variation (asphalt grain, concrete speckle, stucco roughness).
+
+- Instance parameters where tunable (e.g. wetness, ageing).
+
+## Geographic data provenance
+
+- OSM extract is layout data only — not authoritative for façade, height, or pavement detail.
+
+- DEM from 3DEP 1 m; elevation verified against cross-sections in `Geo/verification/`.
+
+- Reference photography (local, gitignored) drives manual façade work.
+
+## QA harness
+
+- `-qaselftest`: core ticker (not world timer) so pause cannot freeze the test that proves pause works.
+
+- `GigLine SIM` / `GigLine GROUND`: TEMP diagnostic logging, to be removed before release tag.
+
+- Screenshot approval: human must tick `Screenshots/README.md` before visual work is marked done.
+
+# Architecture Decisions
+
+## ADR-1: Dynamic-only lighting for the demo
+
+- **Context**: The demo is a fixed daytime scene. Stationary lights demand a lighting build and produce "LIGHTING NEEDS TO BE REBUILT" warnings.
+
+- **Decision**: `r.AllowStaticLighting=False`, all lights `MOVABLE`.
+
+- **Consequences**: No bake step, no warning, simpler iteration. Slightly higher GPU cost per frame (no baked shadows) — acceptable for the demo scope.
+
+## ADR-2: Materials authored in Unreal, not imported from Blender
+
+- **Context**: FBX→Unreal import maps all Blender diffuse colours to white. Flat colour materials do not survive the pipeline.
+
+- **Decision**: Build all materials (asphalt, concrete, stucco, façade stone, road paint) directly in Unreal with procedural nodes.
+
+- **Consequences**: Materials cannot be previewed in Blender look-dev. Must round-trip to Unreal for visual check. But: full PBR control, world-space noise, no import surprise.
+
+## ADR-3: Complex-as-simple collision on terrain via C++ helper
+
+- **Context**: UE 5.8 removed `bUseComplexAsSimpleCollision`. Python cannot set `CollisionTraceFlag` on `StaticMesh`/`BodySetup` at all. The Interchange default is bbox-only simple collision, which placed an invisible lid 8 m above the street.
+
+- **Decision**: `UGigLineAssetTools::SetComplexCollisionAsSimple` (C++) forces `CTF_UseComplexAsSimple` and saves the asset.
+
+- **Consequences**: One C++ helper class. The flag must be saved on the asset (not just the map). No Python workaround exists.
+
+## ADR-4: Reset captures StartLocation on first grounded frame
+
+- **Context**: `BeginPlay` captures `StartLocation` at the PlayerStart, which is above grade (Z 600) so the capsule does not spawn embedded. Every reset dropped the player 1.4 m back into the air.
+
+- **Decision**: Repeating 0.25 s timer captures `StartLocation` once the character reports `IsMovingOnGround()`, then clears itself.
+
+- **Consequences**: Reset is correct. A one-shot timer at 2 s is wrong (fires after walking begins, records mid-stride position).
+
+## ADR-5: Core ticker for QA self-test, not world timer
+
+- **Context**: Pausing the game stops world timers. A timer-driven test freezes exactly when it proves pause works.
+
+- **Decision**: `FTSTicker::GetCoreTicker()` drives the `-qaselftest` harness.
+
+- **Consequences**: Test runs even while paused. Must be enabled explicitly (`-qaselftest`), never in normal play.
+
+## ADR-6: South = +Y, north = −Y in Unreal
+
+- **Context**: The street mesh established this convention: `Sidewalk_North` has Y range −1912..−1053, `Sidewalk_South` has +718..+1447.
+
+- **Decision**: Adopt it project-wide. Never place a building by assumption; always verify against a street mesh or neighbour.
+
+- **Consequences**: Matches Blender’s north→+Y after the Y-flip in the `ue_metric_v1` export preset.
+
+## ADR-7: Headless Blender via bpy scripts, not MCP
+
+- **Context**: Blender skill packs assume an MCP server; the project does not run one.
+
+- **Decision**: All Blender work driven by Python scripts in `Tools/`. Skill packs used as method guides (checklists, naming, proportions) only.
+
+- **Consequences**: Scripts are version-controlled and repeatable. No live Blender session needed for CI.

+## Quality Requirements Overview
+
+| Category | Requirement | Priority |
+| --- | --- | --- |
+| Performance efficiency | 60 FPS at 2560×1440, documented preset, no frame generation | 1 |
+| Reliability / Terrain | Zero raycast holes across sidewalks and carriageway (84-sample transect) | 1 |
+| Accuracy / Fidelity | Building placement matches reference photography within ~1 m | 2 |
+| Accuracy / Fidelity | Street scale (lane width, sidewalk width) within ~10 cm of measured profile | 2 |
+| Usability | WASD + mouse look, jump, reset (R), pause (Escape) — no tutorial needed | 2 |
+| Maintainability | Fresh checkout builds with documented engine installation | 2 |
+| Portability | Linux build packages and runs; Windows build ships | 3 |
+
+## Quality Scenarios
+
+| ID | Source/Stimulus | Response | Metric |
+| --- | --- | --- | --- |
+| QS-1 | Player walks both sides of the demo | No fall-through, character stays at ground Z | 0 raycast holes in 84-sample transect |
+| QS-2 | Player holds W for 2 s on flat road | Character moves forward | ≥ 200 cm displacement, Z constant within ±5 cm |
+| QS-3 | Player presses R | Character teleports to spawn | < 100 cm from `StartLocation` |
+| QS-4 | Player presses Escape | Game pauses, cursor appears | `IsGamePaused()` = true |
+| QS-5 | Player presses Escape while paused | Game unpauses, cursor hides | `IsGamePaused()` = false |
+| QS-6 | Game runs on dev workstation at 1440p | Frame rate stable | ≥ 60 FPS, 99th percentile ≥ 55 FPS |
+| QS-7 | Fresh checkout + engine install | Build succeeds | Exit code 0, runnable binary produced |
+
+# Risks and Technical Debts
+
+| ID | Risk / Debt | Priority | Mitigation |
+| --- | --- | --- | --- |
+| R-1 | Terrain bbox proxy misdiagnosed as fall-through — already fixed, but the root-cause path (Interchange defaults to simple collision) could recur on reimport | High | `UGigLineAssetTools` runs in the build script; always reassert complex-as-simple after any reimport. Documented in `MEMORY.md` and ADR-3. |
+| R-2 | Blosm 3Dsimple on Blender 5.2 — worked around, not resolved; `3Drealistic` mode untested | Medium | Pin Blosm 2.7.28 and Blender 5.2 LTS; test realistic mode before depending on it. |
+| R-3 | Kerb height is an assumption (DEM does not resolve it) | Medium | Record the assumption in `Geo/verification/`; measure from reference photography if possible; mark as unresolved until verified. |
+| R-5 | `GigLine SIM` / `GigLine GROUND` TEMP diagnostic logging still in `GigLineCharacter.cpp` | Medium | Strip behind a cvar or remove entirely before the `v0.1.0` release tag. |
+| TD-1 | Materials are Unreal-only — no Blender preview round-trip | Low | Accepted (ADR-2). Look-dev happens in UE; screenshot review catches issues. |
+| TD-2 | No CI pipeline — all builds and QA are manual on the dev workstation | Low | Acceptable for `0.x`. CI is a `0.3.0+` concern. |
+
+# Glossary
+
+| Term | Definition |
+| --- | --- |
+| Blosm | Blender add-on (2.7.28) that imports OSM data as 3D building and street blockouts. Used for layout only — not authoritative for façade or height. |
+| PIE | Play In Editor — an Unreal Editor feature that runs the current map as a live game session inside the editor window, with full game code, input, and physics, without packaging a build. Used for interactive verification (walk, reset, pause) before the scripted QA self-test. |
+| Complex-as-simple collision | `CTF_UseComplexAsSimple`: Unreal collision mode where the render mesh triangles are used as the collision surface, instead of a simplified proxy. Required for terrain so the player walks on the actual ground shape. |
+| DEM | Digital Elevation Model. 3DEP 1 m resolution GeoTIFF covering the demo bounds. Source of terrain heightfield. |
+| El Capitan | El Capitan Entertainment Centre, 6838 Hollywood Blvd. The hero building of the demo. |
+| Enhanced Input | Unreal’s modern input system (UE 5+). Uses Input Actions (`IA_*`) and Input Mapping Contexts (`IMC_*`) instead of legacy axis/action bindings. |
+| EPSG:26911 | UTM zone 11N, the projected CRS used for the demo area. Local origin recorded in `Geo/`. |
+| Hero façade | The detailed, reference-calibrated model of the El Capitan building frontage. |
+| MPFB | MakeHuman Plugin for Blender (2.0.18). Generates parametric human base meshes with rigs and baked materials. |
+| PlayerStart | Unreal actor that defines where the player pawn spawns. Positioned above grade so the capsule does not embed in the floor on spawn. |
+| QA self-test | The `-qaselftest` command-line switch that runs an automated behaviour check (walk, reset, pause, ground transect) via a core ticker. |
+| Site | The terrain, road, sidewalks, kerbs, and crossing markings — the ground-level infrastructure of the demo area. |
+| Squash merge | Git merge strategy that compresses all branch commits into one commit on `main`, keeping a linear history. |
+| Swept transect | A QA technique that raycasts vertically at regular intervals along a path (e.g. every 200 cm along both sidewalks and the carriageway) and counts holes (misses). Zero holes = the block is fully walkable. |
+| UE | Unreal Engine — Epic Games' real-time 3D creation platform (version 5.8.4 in this project). Comprises the Unreal Editor (including PIE, content browser, viewport, blueprint editor), a C++ game framework, and runtime systems for rendering (Vulkan RHI on Linux), physics (Chaos), and input (Enhanced Input). The game project is `GigLine.uproject`; game code is a single C++ module in `Game/GigLine/Source/GigLine/`. |
+| World Partition | Unreal's world composition system for large open-world levels. Not yet used in `0.1.0` but planned for `0.3.0+` driving routes. |
+| Y convention | In Unreal, south = +Y, north = −Y (confirmed from street mesh orientation). In Blender, north = +Y; the `ue_metric_v1` export preset flips Y. |

 - **Reference photography retention.** Decided 2026-11-06: reference images are **not** committed.

+1. **Attribution** — credit the database, with a notice visible to users, and provide a link to the licence.
+2. **Share-alike** — a derivative database (including a "Produced Work" from it) must be offered under ODbL, and changes must be made available.
+3. **Keep the data open** — do not add technical or legal restrictions that prevent others from using the database under ODbL.
+4. **No database right / extraction limits** — substantial extraction/use must follow the licence's "extraction and reuse" terms.
+
+Important nuance: ODbL governs the **database** (the OSM data as a collection and the knowledge it encodes). **Separate creative content** — art, code, models authored by the project — is not a "database" and does not carry the share-alike obligation. The game's own code and artist-authored geometry are project-owned (CC0 per `LICENSE`).
+
+## 3. Where the project stands
+
+| Obligation | Held by | Evidence |
+| --- | --- | --- |
+| Attribution in the game | **Yes** — on-screen credit every frame | `AGigLineHUD` draws "© OpenStreetMap contributors" and "Data © OpenStreetMap contributors, ODbL 1.0 — openstreetmap.org/copyright" bottom-left (`GigLineHUD.h` lines 29/33) |
+| Attribution in the repo | **Yes** — provenance + licence recorded | `THIRD_PARTY_NOTICES.md` Geographic data table; `Geo/manifests/2026-11-06-osm-api-map.md` |
+| Licence text available | **Yes** — link + notice | HUD link to openstreetmap.org/copyright (ODbL); THIRD_PARTY_NOTICES points at ODbL 1.0 |
+| Source data available (share-alike enabler) | **Yes** — the exact extract is committed, with bbox/date/hash | `Geo/raw/osm-api-map-2026-11-06.osm` + manifest |
+| Derivative database offered under ODbL | **Recorded as a decision** — see §4 | This document |
+
+## 4. Decision: posture for the derived geometry
+
+The OSM-derived block geometry (streets, footprints, sidewalks) is treated as a
+**Produced Work / derivative database** of the OpenStreetMap database.
+
+- The **share-alike obligation is accepted for the data layer only**. The
+  release must carry: (a) the on-screen attribution (implemented), (b) the ODbL
+  link (implemented), and (c) an offer of the OSM source for the geometry —
+  satisfied by the committed raw extract plus its manifest.
+- **Project creative work (code, shaders, artist-authored façades, textures) is
+  NOT under ODbL.** It remains project-owned CC0 (see `LICENSE`) and carries no
+  share-alike obligation. Only geometry that can be argued to encode OSM
+  database facts (streets, building footprints, sidewalk layouts) is in scope.
+- **No new obligation is created by the DEM**: 3DEP is US Government public
+  domain and is independent of ODbL.
+- **Do not** import OSM imagery/panoramas as textures (OSM map tiles or aerial
+  imagery are separately licensed); the project already treats OSM as layout
+  only (`Docs/licensing.md` rule 3).
+
+Release checklist items this lands:
+
+- [x] In-game attribution shown (HUD).
+- [x] ODbL notice + link (HUD + THIRD_PARTY_NOTICES).
+- [x] Source OSM data committed with provenance (manifest: date, bbox, SHA-256).
+- [x] Posture recorded here for the release gate.
+
+## 5. Remaining (tracked separately)
+
+- **Blosm add-on licence** is still `pending` in THIRD_PARTY_NOTICES (tool-only,
+  not distributed — must be checked once, not a release blocker for ODbL).
+- Façade signage/trademarks: separate rights from the photograph, own the
+  geometry; not an ODbL question (see THIRD_PARTY_NOTICES "Reference
+  photography" rules).
+
+## 6. Sources checked
+
+- ODbL text: <https://opendatacommons.org/licenses/odbl/1-0/>
+- OSM licence summary: <https://www.openstreetmap.org/copyright>
+- ISPRS/ODbL practice notes on derived game geometry from OSM footprints
+  (objective standard: attribution + produced-work offer, share-alike limited
+  to the data layer).
+
+Not reviewed here (out of scope for this item): engine redistribution terms
+(Epic), MPFB asset terms, street-prop reuse terms — all tracked in
+`THIRD_PARTY_NOTICES.md`.

+## `0.1.0` — Placement vs references — record (2026-11-08)
+
+Checked against the reference photography (`Art/reference/`) and the Geo measurements
+(`Geo/verification/*`). Build under test: current `main` content, DemoMap rendered via
+`Tools/render_screenshots.sh` (2026-11-08, Vulkan SM5, 1920×1080); engine positions
+probed from the DemoMap (commandlet, 2026-11-08).
+
+### Placement and scale (in-engine ↔ reference)
+
+| Quantity | In-engine (probed world-space) | Reference | Match |
+| --- | --- | --- | --- |
+| Road (Hollywood Blvd carriageway) | Y −13.82..+10.47 m → **24.3 m** | crossing ways 20.9–25.9 m | ✓ within range |
+| South sidewalk strip | 7.3 m (bbox incl. kerb apron); built walkable strip 4.0 m per `Art/blender/README.md` | 12.6 m centreline offset; strip width from setback arithmetic | ✓ offset 12.5 m ≈ ref 12.6 m |
+| North sidewalk strip | 8.6 m (bbox); built strip 5.3 m | 13.6 m centreline offset | ✓ offset 13.2 m ≈ ref 13.6 m |
+| Kerbs | 3.3 m apron face to 0.13 m upstand | 0.15 m assumption; photo check pending (`0.1.1` Kerb height item) | ≈ (recorded deviation) |
+| Hero façade (6840 El Capitan Ent. Ctr.) | X −146.38..−120.34 m (26.0 m frontage), Y +13.0..+25.6 m from road centre (13.0 m deep) | 6840 setback 14.5 m; 25.75 m frontage (resolved) | ✓ frontage; setback ~1.5 m deeper than ref (recorded) |

+
+### Visual comparison (demo views vs references)
+
+| Shot | Reference(s) used | Verdict | Notes |
+| --- | --- | --- | --- |
+| `review-demo-spawn-view` | `hollywood/el-capitan-facade-day-*` (CC BY 2.0), `el-capitan-entrance/*` | PASS | Facade frontage, column rhythm and neighbour massing match; camera frames the whole block from the north sidewalk. |
+| `review-demo-street-level` | `hollywood/el-capitan-theatre-blade-sign-*`, `premiere-staging-*` | PASS | Street-level colonnade + frontage neighbours; sidewalk depth consistent with the blade-sign frame. |
+| `review-demo-crossing` | street-profile crossing s=130.1 m | PASS | Zebra markings visible along the crosswalk; kerb flushed at the crossing. |
+| `review-demo-north-buildings` | north-side OSM positions; TCL/Tussaud's `Art/reference/north-*` | PASS | Camera re-pointed 2026-11-08 (was 9.5 km west → 85% sky); buildings now framed. Flat blockout surfaces are the `0.1.4` scope. |
+
+### Deliberate deviations recorded
+
+- **North/south building surfaces are flat blockouts** (bloblike, no façade detail). Detail texturing/façade style is the planned `0.1.4` (Proper building façades) work; placement and massing are what this check verifies.
+- **Kerb upstand 0.13 m as built vs 0.15 m assumed**; the DEM cannot resolve a kerb — tracked in `0.1.1` (Kerb height assumption).
+- **Sidewalk surface detail** (railings, pavers, domes) not modelled — outside `0.1.0` scope.
+- **Crossing ramps are kerb flushes, not graded ramps** — the `0.1.1` Crossing ramp gradient item.
+- Site identity (the neoclassical hero with motto band) matches the 2009 façade photograph and the 1922 Masonic elevation within blockout fidelity.
+
+Pre-check method: `Tools/judge_screenshot.py` (vision model) flagged the simplified
+flat surfaces as "unexpected" — those flags are the deliberate deviations above, not
+placement errors. Final verdict is by human review of the shots in `Screenshots/demo/`.
+
+## `0.1.0` — Collision and packaging — audit note (2026-11-08)
+
+Run on the packaged build (`GigLineQA`, Development, Vulkan SM5) with `-qaselftest`.
+
+- **Transect (holes/gaps):** 1456 samples over 16 rows — lane centres **plus the
+  kerb/road/sidewalk seam Ys** (−1382, −1053, +718, +1047 and neighbours) and
+  X −20000..−2000. Result **0 holes**. (The old 84-sample check covered only 3
+  lane centres; the seam rows are what this check adds.)
+- **Invisible-wall probe:** horizontal traces 30 m long, grounded at 160 cm above
+  the local ground, along the road and both seam rows. Result **0/35 blocking hits
+  inside 21 m** — no invisible walls or misplaced blockers in the street envelope.
+  (First pass used a fixed Z 160 start; the street is at Z ~366, so the probe
+  started inside the earth and reported every row as a dist-0 blocker. Grounding
+  the probe fixed that measurement bug.)
+- **Walk / reset / pause:** 761 cm in 2 s (Z steady 456), reset 0 cm, pause
+  `IsGamePaused()=1`, unpause 0 — all PASS.
+- Packaging: the packaged build launches, reaches gameplay, and the QA run quits
+  cleanly. The `GigLineShotActor` screenshot rounds are suppressed under
+  `-qaselftest` so they cannot quit the run before the audit phases.
+- Caveat recorded: ground Z extremes (−12 m / 3000 cm) are trace-start/terrain-edge
+  artifacts of the widened extent, not walkable holes — the walkable corridor is
+  continuous (walk + transect both PASS).
+
+## `0.1.0` — 60 FPS at 1440p — record (2026-11-08)
+
+**Build under test:** packaged `GigLineQA` Development, UE **5.8.4**, Vulkan SM5,
+NVIDIA 615.78.08 (RTX 5070 Ti), Bazzite, Ryzen 7 7700X, 64 GB RAM.
+
+**Documented quality preset** (applied via `-ExecCmds`): all scalability groups at
+3 = Epic — `sg.ViewDistanceQuality 3, sg.ShadowQuality 3,
+sg.GlobalIlluminationQuality 3, sg.ReflectionQuality 3, sg.PostProcessQuality 3,
+sg.TextureQuality 3, sg.EffectsQuality 3, sg.FoliageQuality 3, sg.ShadingQuality 3`.
+
+**Upscaling state (recorded from the run):** `r.AntiAliasingMethod=4` → **TSR on**,
+default screen percentage, `r.VSync=0` (**off**), frame generation **off/unavailable**
+(`r.Streamline.FrameGeneration.Mode` absent → -999).
+
+**Route:** the deterministic `-qaselftest` traversal — spawn
+`(-13336,-1150,456)`, walk forward (+Y) into the block for 2 s. Frame times are
+captured every frame over that route (829 frames), not a single sample.
+
+**Result at 2560×1440:**
+
+| Metric | Value |
+| --- | --- |
+| Frames captured | 829 |
+| Average | **2.42 ms → 414 fps** |
+| p50 | 2.38 ms |
+| p95 | 2.71 ms |
+| p99 | 3.01 ms (≈332 fps) |
+| Max | 4.00 ms |
+
+**Verdict: PASS** — worst-case p99 is ~3 ms (≈330 fps), far above the 60 FPS
+target without frame generation.
+
+**Variance note:** two back-to-back runs measured ~9.2 ms (≈108 fps) when another
+game instance / busy compositor overlapped the capture; repeated clean runs
+(windowed and fullscreen, Wayland and X11 drivers, window focused) all measured
+~2.4–2.5 ms. The high outlier is recorded here rather than hidden.

+- `[x]` Install `git-lfs`, `cmake`, `ninja-build`, `clang` as an ostree layer, reboot, then `git lfs install`. Done: `git-lfs 3.7.1`, `clang 23.1.4`, `cmake 4.3.0`, `ninja 1.13.2`; lfs filter active, `Tools/check-lfs.sh` passes.

+- `[x]` **Human step.** Create an Epic account, accept the Unreal license. Done on 2026-11-06 with the account email recorded locally; no credentials stored in the repository.
 - `[x]` **Human step.** Acquire one pinned engine build. Two routes:
  - **Launcher build**: install the Linux Epic Games Launcher, download the pinned engine version, install to the DATA volume, and disable auto-update so the pin holds.
-  - **Source build**: clone the pinned `release` branch from the Epic Games GitHub organisation, then `./Setup.sh`, `./GenerateProjectFiles.sh`, `make -j16`. Budget 120–200 GB and a multi-hour first build on 16 threads.
-  **5.8.4** downloaded to `/run/media/system/DATA/Downloads/Linux_Unreal_Engine_5.8.4.zip`: 39 819 212 076 bytes (37.08 GiB), ZIP central directory present with 299 959 entries, `Engine/Build/Build.version` reports **5.8.4**, changelist 58902052, `++UE5+Release-5.8`.

 - `[x]` Extract to the DATA volume and record the install path. Done 2026-11-07: `/run/media/system/DATA/Engines/UE_5.8.4`, 73 GiB on disk, extraction verified by full headless editor start.
 - `[x]` Resolve the engine version: **5.8.4 pinned** (see the decision below). The 5.2.0 archive (19.59 GiB, CL 25360045) remains on disk as a fallback only and should be deleted once the pin is trusted.

 ## Coverage limits

 - Building interiors, heights above the tagged value, and pavement widths are not in this data. Treat all of it as layout.
 - The `height` tag exists on some buildings and is absent on others (`6838` has only `building:levels`, `6922` has neither). A missing tag is not a zero height.
 - The extract has no elevation. The DEM decision is still open; see `ROADMAP.md`.

+## 2026-11-08 — Documentation toolchain installed; asciidoc→markdown conversion
+
+- **pandoc 3.13** installed at `~/.local/bin/pandoc` from the [GitHub release tarball](https://github.com/jgm/pandoc/releases/tag/3.13) (statically linked, 161 MB). The Fedora repos carry only `ghc-pandoc` (Haskell library), not the CLI.
+- **asciidoctor 2.0.26** layered via `rpm-ostree install rubygem-asciidoctor` — **pending reboot** to activate. As a workaround, a distrobox Fedora container (`distrobox enter arch-convert`) runs asciidoctor without rebooting.
+- **prettier 3.9.10** installed globally via npm (Node v24.20.0). Project config: `.prettierrc` (`proseWrap: never`, `tabWidth: 2`), `.prettierignore` (skips `Binaries/`, `*.uasset`, `.agents/`).
+- **Conversion chain:** `.adoc` → `asciidoctor -b docbook5` → `.xml` → `pandoc -f docbook -t gfm` → `.md` → `prettier --write`. Pandoc's built-in `asciidoc` reader cannot handle Asciidoctor tables or attributes — it must go through docbook5.
+- **Post-processing fixes:** glossary `cols="e,2e"` emphasis leaks italic into cell content (strip `*...*` wrapping), `®` from the R key binding becomes `(R)`, anchor IDs `{#...}` stripped, escaped quotes/brackets normalised.
+- **All `.adoc` files removed.** Markdown is the canonical format. Architecture doc lives in `Docs/Architecture/` as 13 section `.md` files + combined `architecture.md`.
+- All `.md` in the repo passes `prettier --check` (23 files formatted, `.agents/` excluded as vendored content).
+
+## 2026-11-08 — QA branch merged; demo is walkable
+
+- **PR #7** squash-merged to `main` as `52b1212` — terrain collision fix, spawn correction, `UGigLineAssetTools`, `HighResShot` fix, `-qaselftest` harness.
+- **QA self-test results (from merged main):** walk 750 cm / 2 s (Z steady 456), reset 0 cm from spawn, pause/unpause pass, transect 84 samples / 0 holes (ground Z 317..395).
+- **Traversal release check closed:** the swept transect measures walkability rather than assuming it.
+- `gameplay-crossing-0.1.0` branch deleted (already merged); `gig-line-judge` worktree removed.
+- `qa-input-collision-fix-0.1.0` branch still exists locally/remote (squash merge has no shared ancestry, `git branch -d` refuses; delete with `-D` after release tag).
+- `GigLine SIM` / `GigLine GROUND` TEMP diagnostic logging still in `GigLineCharacter.cpp` — must be removed before `v0.1.0` tag.
+
+## 2026-11-08 — Reset was returning to mid-air; QA self-test switch
+
+- **`ResetToStart()` restored a `StartLocation` captured in `BeginPlay`**, which is the PlayerStart position _above_ grade (Z 600) so the capsule never spawns embedded. Every reset therefore dropped the player 1.4 m back into the air. Fix: capture `StartLocation` on the first grounded frame (repeating 0.25 s timer, cleared once captured) — not a one-shot timer, which can fire after the player has already started walking and record a mid-stride position.
+- **`-qaselftest`** drives the checks headlessly and logs `GigLine QA: ... PASS/FAIL`. It runs on a **core ticker, not a world timer**: pausing the game stops world timers, so a timer-driven test freezes exactly when it proves pause works.
+- Current results: walk 746 cm / 2 s with Z steady, reset 0 cm from spawn, pause `IsGamePaused()` 1, unpause 0, transect 84 samples / 0 holes (ground Z 317..395).
+
+## 2026-11-08 — The fall-through was an 8 m invisible box (QA branch)
+
+- **Symptom:** player "spawned above ground but never fell", sat at Z 909, `fall=0`, `mode=1` (Walking), no fall-through, view looked plausible so it was mistaken for working.
+- **Cause:** `Terrain_DEM` had only a **bounding-box simple collision proxy** (Interchange default). A line trace down at _every_ Y through the block hit `Demo_Terrain_DEM` at exactly **819** — the mesh bbox max Z. The whole street was under an invisible lid; the pawn stood on the box, 8 m above the road.
+- **Proof:** a debug `LineTraceSingleByChannel` profile at Y −1912…+1447 reported `top=819 actor=Demo_Terrain_DEM` for the entire street. After the fix it reports `Sidewalk_North 395`, `Road_Hollywood 366`, `Sidewalk_South 317`.
+- **Fix:** force complex-as-simple collision on the terrain. Python **cannot** set it (`StaticMesh`/`BodySetup` expose no such property; `dir()` shows only `lod_for_collision`). Added `UGigLineAssetTools::SetComplexCollisionAsSimple` in the C++ module (`BodySetup->CollisionTraceFlag = CTF_UseComplexAsSimple`, UE 5.8 no longer has `bUseComplexAsSimpleCollision`).
+- **Second gotcha:** the flag lives on the **asset**, not the map. Setting it in a builder session and saving only the `.umap` loses it — `EditorAssetLibrary.save_loaded_asset()` is required, otherwise the next run reloads the bbox proxy.
+- **Third gotcha:** `HighResShot 1280 720` means **multiplier 1280** (UE warns "the high resolution screenshot multiplier is too large for your system"). The correct form is `HighResShot 1280x720`.
+- Resulting spawn: `(-13336, -1150, 600)` — inside the carved corridor, lands on the road at Z 456 (feet 368 on road top 366).

Symptom: `skill("archviz")` unresolvable even though `archviz/SKILL.md` exists.
 - **Fix applied:** 94 symlinks in `~/.agents/skills/<pack>` → `<repo>/.agents/skills/blender-skills/<pack>/`. The catalog then lists all of them (verified by calling `skill` on `collision-proxy`: base dir resolves through the link). `references/` stays unlinked — it is a shared folder with no `SKILL.md`, not a pack.
 - **The AGENTS.md "MCP-driven" caveat is overstated.** 41 of 94 SKILL.md mention MCP, mostly only in the `description` line; the bodies are method guides (naming, proportions, validation checklists) that work headless. Do not skip a pack because it advertises MCP.
 - **Skill names in AGENTS.md/TODO.md all resolve** except `references`, which is the folder above, not a pack.

 ## 2026-11-07 — ReviewMap corruption: deprecated level calls + save-order bug

 - **`EditorLevelLibrary.load_level`/`new_level` are deprecated no-ops in `-nullrhi` commandlets** (they return without switching worlds, so staged actors land in whatever world is current and get saved over the wrong map). Use the `LevelEditorSubsystem`: `unreal.get_editor_subsystem(unreal.LevelEditorSubsystem).load_level(path)` actually switches. Symptom was ReviewMap containing Demo actors + `ShotSequencer`.
- **Map-save ordering bug in `Tools/ue_build_review_map.py`**: the script saved ReviewMap *after* the DemoMap section, but the switch back to ReviewMap fails silently because the map only exists in memory at that point — so the final `save_map` wrote the demo world over ReviewMap.

- **Blender flat diffuse colours do not survive FBX -> Unreal.** Every site mesh (road, sidewalks, kerbs, crossing paint) imported with a material asset that had a default *white* base colour, and the terrain imported with `WorldGridMaterial` (UE's bright grey grid). That — not the sun — is what made the demo look blown out and washed white. Fix: create the colours in UE (`M_Asphalt`, `M_Concrete`, `M_Ground`, `M_RoadPaint` via `Constant3Vector`) and assign them per actor in `Tools/ue_build_demo_map.py`.

 - **Auto-exposure makes review shots non-comparable**: the same road rendered washed-out in one framing and near-black in another because each camera saw a different amount of sky. Fix: an unbound `PostProcessVolume` with `AEM_HISTOGRAM` and `auto_exposure_min_brightness == auto_exposure_max_brightness` (fixed exposure). Do not use `AEM_MANUAL` + `auto_exposure_bias` — a bias of 11 blew the whole frame out.
 - **`DirectionalLightComponent.light_color` takes a `Color` struct, not `LinearColor`** (`unreal.Color(r=255,g=245,b=230,a=255)`); passing `LinearColor` raises a nativize error.
 - **One band per object loses geometry downstream.** `crossing_band()` created `Crossing_Markings` each call, so Blender renamed the second and third to `.001`/`.002`; `site_assembly.py` appends by exact name, so only one crossing ever reached the game. Build all bands into a single mesh instead of one object per band.
 - **Street arc length -> UE X:** s=0 is the west end of the block (UE X −27966 cm) and s increases eastward, so the designated mid-block crossing at s=130.1 m is UE X ≈ −14956, not the −24291 used by an earlier camera (that is the s=36.6 crossing).
- **Camera placement in the demo map needs the mesh bounds, not intuition.** The hero façade body spans UE Y −1457..−200, so a "street level" camera at Y −400 is *inside* the building and renders its unlit back face. Read `get_bounding_box()` on the staged meshes before choosing a camera.

+
+- **"Stuck" window = wrong default map.** A plain `./GigLine.sh` opened `/Engine/Maps/Templates/OpenWorld` (empty engine template) instead of the demo, so nothing was interactive. `GameDefaultMap` was in `DefaultGame.ini` and not applied; it must live in `DefaultEngine.ini[/Script/EngineSettings.GameMapsSettings]` with `GlobalDefaultGameMode`. Verified: plain launch now loads `/Game/Hollywood/DemoMap`. Evidence: `LogLoad: LoadMap: /Engine/Maps/Templates/OpenWorld`.
+- **Input assets were pruned from the pak.** The Enhanced Input assets under `/Game/Input` were only soft-referenced at runtime, so the cooker excluded them (cook `ReferencedSet.txt` had zero `/Game/Input` lines -> all inputs nil at runtime). Fix: hard-reference via `ConstructorHelpers::FObjectFinder` in the character ctor (cooker follows hard refs) + `+DirectoriesToAlwaysCook`. Packaged log then showed `ctx=ok move=ok ... jump=ok`.
+- **Character fell through** the site: site meshes staged MOVABLE + PlayerStart far past the north sidewalk. Fix: STATIC mobility + explicit collision (QUERY_AND_PHYSICS/WorldStatic/BlockAll) and PlayerStart at Y -1200 on the sidewalk. Packaged run: `grounded=1 movement=Walking`.

-  character measures Z 0..83 cm. One warm key light plus sky fill.
- **Cubes**: `Cube_ScaleTest_A` rests on the floor, `Cube_ScaleTest_B` floats at
-  Z 2 m; both are exactly 1 m — the scale reference.
- **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 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

-  `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.

-
-### Environment setup
-
-Status detail in [Docs/setup.md](Docs/setup.md); pins in [Docs/toolchain.md](Docs/toolchain.md). The workstation audit is local only.
-
- [x] Update Bazzite using its supported mechanism; verify NVIDIA driver and Vulkan operation.
- [x] Register an Epic account and accept the Unreal license; obtain a pinned Linux engine build or build from Epic's authorized source repository.
- [x] Validate Unreal runs on Bazzite before asset production (not an officially supported distribution). 2026-11-07: headless `-NullRHI` smoke test **and** full editor GUI launch with the Vulkan RHI passed — device `NVIDIA GeForce RTX 5070 Ti`, Vulkan loader 1.4.350, `VULKAN_SM5`, map check 0 errors. Only benign log noise (Android Turnkey status, telemetry DNS failures).
- [x] Install the engine-required compiler/SDK, Git, Git LFS, and an editor; use Distrobox for isolated CLI dependencies where useful. clang 23.1.4 / cmake 4.3.0 / ninja 1.13.2 installed; this engine build bundles no Linux clang, so the system compiler is the toolchain. **Accepted 2026-11-07:** the first C++ game-module compile and link (`libUnrealEditor-GigLine.so`) succeeded with system clang.
- [x] Pin Blender, MPFB, Blosm, and QGIS versions; confirm add-on compatibility; record in `docs/toolchain.md`. Done: Blender 5.2.0 LTS, MPFB 2.0.18, Blosm 2.7.28, QGIS 4.2.3 with PROJ 9.9.0 (stale `lts` removed 2026-11-07), Unreal 5.8.4 finalized as pin after the editor GUI launch.
- [x] Create repository structure (`Game/`, `Art/`, `Geo/`, `Tools/`, `Docs/`) with LFS tracking and ignore rules applied.
- [x] Keep project and Derived Data Cache on SSD storage; reserve several hundred GB for engine, assets, caches, builds.
-
-### Project bootstrap
-
- [x] Create a C++ Unreal project with Blueprint gameplay iteration and Enhanced Input. Created 2026-11-07 at `Game/GigLine/GigLine.uproject` (primary game module + default game mode, Enhanced Input plugin + input classes in `Config/DefaultInput.ini`); `GigLineEditor` target compiles clean with system clang (UBT: Result Succeeded).
- [x] Package and launch a blank Linux build. 2026-11-07: UAT `BuildCookRun` (cook + build + stage + pak, Development config) succeeded in 56 s; 1.1 GiB archive at `/run/media/system/DATA/Builds/GigLine` (outside the repo, uncommitted). `GigLine.sh` launched on the desktop session, created a Vulkan swapchain, and rendered 759 frames across a 60 s test. Known minor: one handled `PSOPrecache` ensure fires at exit only; not blocking, watch it in `0.1.x`.
- [x] Export one static mesh from Blender and import into Unreal; verify scale and materials. 2026-11-07: calibration scene (three 1 m cubes at origin / +10 m east / +10 m north) exported from Blender with preset `ue_metric_v1` (`Tools/scale_test_export.py`) and imported headless via `Tools/ue_scale_test_import.py`. Measured in UE: cubes exactly 100.00 cm, origin preserved, material imported. Axis mapping: **east → +X, north → −Y, up → +Z** (the Y mirror is inherent to the right-handed→left-handed conversion; importer handles winding).
- [x] Export one MPFB character with baked materials and deform skeleton; verify import. 2026-11-07: MPFB 2.0.18 generated human (19 158 verts, 1.66 m tall) + standard rig with weights (137 bones) + v2 skin baked to a 1024² diffuse texture (`Tools/mpfb_character_export.py`, export preset `ue_character_v1`). Imported headless (`Tools/ue_character_import.py`) into `/Game/Test/Character`: `SkeletalMesh` + 138-bone `Skeleton` + `Material` with the baked `Texture2D` assigned to slot 0. Quirks recorded: 5.8 Interchange skips materials for skeletal FBX imports (finished in script); Blender 5.2 dropped the FBX `armature_nla` option; the baked image needs `image.filepath` set for FBX to reference it.
- [x] Document initial setup in `Docs/`: engine install, project checkout, fresh-checkout build procedure. 2026-11-07: `Docs/setup.md` reconciled with reality (all engine/bootstrap items marked done with evidence); `Docs/build.md` completed with the fresh-checkout build, packaging, and headless-content-check procedures plus known engine quirks.

-### Geographic data
-
-Tools ported 2026-11-07: every geographic script now lives in `Geo/tools/` with `Geo/README.md` listing its purpose, and the Blender-side builders moved next to their outputs in `Art/blender/*/`, importing the shared helpers and the single unit conversion from `Geo/tools/osm_common.py`.
-
-| Tool | Purpose |
-| --- | --- |
-| `osm_common.py` | parse `.osm`, stitch/clip streets, PROJ projection, **the only metres→centimetres conversion** |
-| `block_report.py` | streets, boundary intersections, building set by side |
-| `block_height_report.py` | every block building with its height source; 3 of 15 are placeholder guesses |
-| `street_profile.py` | carriageway from crossings, sidewalk offsets, setbacks |
-| `street_section.py` | DEM cross-sections, crown and gutters |
-| `elevation_probe.py` | 3DEP relief sampling |
-| `dem_stats.py` | stdlib tiled-GeoTIFF reader (GDAL does not run on this host) |
-| `asset_metadata.py` | writes and audits the `<asset>.geo.json` sidecars |
-
- [x] Save a versioned OSM extract; document date, bounds, and source in `Geo/`.
- [x] Acquire separately licensed elevation data if needed. Needed and acquired: USGS 3DEP 1 m DEM in EPSG:26911, public domain, NAVD88, 984 KB committed (`Geo/manifests/2026-11-06-3dep-dem.md`); measured relief 3.94 m.
- [x] Download the 3DEP 1 m DEM for the demo bounds, reproject it to EPSG:26911 with the recorded origin and vertical datum, and record the source, clip bounds, and checksum in `Geo/`.
- [x] In QGIS, set a suitable local projected CRS (e.g. EPSG:26911) and record a local origin. EPSG:26911, origin and projected easting/northing are recorded in `Geo/manifests/local-origin.md` with PROJ 9.9.0 control points; QGIS 4.2.3 is installed for the DEM reprojection step.
- [x] Verify the address, building footprints, and demo boundaries for 6840 Hollywood Blvd against source data.
- [D] Import OSM blockouts through Blosm; clean and detail them in Blender. Imported 2026-11-06 and re-framed to EPSG:26911. Tooling for the cleaning pass is now in `Geo/tools/` (height provenance, block report) and `Art/blender/blockout/blosm_blockout.py`. **Still open:** 3 of 15 block buildings carry no height data and render at a placeholder 6.4 m, roofs and facades are untextured, and Blosm `setupScript` façade styles are unused. Earlier: (`Art/blender/blockout/blockout-2026-11-06.blend`, 86 meshes, scale 1:1 against OSM, re-framed into EPSG:26911 with a 0.0 cm affine residual); cleaning and detailing not started.
- [x] Preserve geographic coordinates in metadata; define explicit meter→centimeter conversion to local Unreal coordinates. Done 2026-11-07: the conversion lives in exactly one function (`Geo/tools/osm_common.py::to_unreal_local`) and every exporter must call it; `<asset>.geo.json` sidecars carry position, source, and assumptions for **hero-facade, terrain, street, and blockout**, written and audited by `Geo/tools/asset_metadata.py`, which recomputes each centre from the origin and fails a sidecar that disagrees. Props follow the same schema when they are imported. The frame is defined (`Geo/manifests/local-origin.md`: EPSG:26911, origin Hollywood × Highland, X east / Y north / Z up) and the ×100 conversion is now **verified** by the 2026-11-07 scale test, with the axis mapping recorded (north realizes as UE −Y). Left: build the production export preset for the actual site meshes using these settings.

-### Review scene and player placement
-
-Owner: this session. Scope: the review scene used for all visual approval — the staging, the character's relationship to the ground, and the camera list. Nothing in `Asset production` or `Gameplay` continues until these pass.
-
- [x] Put the character on the ground rather than floating. The floor was a 5 cm slab centred 50 cm down; it is now a 90 m x 90 m x 10 cm slab with its top face at Z 0, and the character measures Z 0..83 cm — feet on the plane (`Screenshots/README.md`).
- [x] Split the scale cubes: one resting on the floor as the ground-contact and scale reference, one held at 2 m so its cast shadow separates from the body.
- [x] Point the scale-cubes camera at both cubes instead of the retired three-cube row.
- [x] **Character placement shot**: `review-player-placement` shows the pawn (`AGigLineCharacter`) staged by `Tools/ue_build_review_map.py` with a cube behind it. Note: the pawn's capsule renders invisible in `-game` because the character has no visible mesh, so the shot shows where the player lands relative to the scene rather than the body.
- [x] **Ground-contact detail shot**: `review-ground-contact`, knee height, close on the feet — the soles meet the floor and the shadow joins them.
- [x] **Shadow-comparison detail shot**: `review-shadow-compare`, both cubes in one frame from a low angle; the floating cube's shadow is detached, the grounded one's touches.
- [x] **Detail shot of the hero façade portals**: `review-hero-portals` from 8 m at eye height now fills the frame with all three doorways. The camera alone was not enough: the doors were flat panels on a solid face, so they were rebuilt as three genuine recesses — plinth split into four piers plus a lintel band, 1.2 m reveal, stone jambs and lintels standing 0.10 m proud, three mullions each. Facade bounds are now exactly Z 0..14.50 m; a jamb overhang had been sinking the model 0.15 m into the ground.
- [x] Document the shot list, camera positions, and what each shot is evidence for in `Screenshots/README.md`; shots use stable names with an approval line (10 review + 4 demo).
- [x] Extend the review floor beyond the hero façade: 160 m square centred on the façade, so façade shots stand on ground instead of the horizon band.
- [x] Delete retired shots: the old `first-person` frame is gone and the camera list is now a single table so a change cannot leave an orphan.
-
-### Character development
-
-The MPFB character asset is planned as the NPC template (see `ROADMAP.md`). Keep it as a standalone character/prefab, not wired into the `AGigLineCharacter` pawn.

- [x] Give the MPFB character asset a standing idle pose so review and NPC shots show a person, not an A-pose bind. Done: `Tools/mpfb_character_export.py --pose idle` folds the A/T-bind arms down to a relaxed standing rest pose (baked via `pose.armature_apply` before export; `upperarm01.L` rest z −0.71 → −1.91 rad), re-exported, re-imported (138 bones), rendered in `review-01-character`.
- [x] Bake a second skin tone or clothing layer, so the character does not read as a grey mannequin in shots. Done: the v2-skin bake came out **black** and slow at 1024², so we synthesize a warm skin-tone diffuse directly (`Tools/mpfb_character_export.py` `make_diffuse`, with a darker shorts-suggestive bottom band) via a stdlib/numpy PNG writer. Character reads warm, not grey. Screenshot approved (`Screenshots/review-01-character`).
- [x] Keep the character as a reusable NPC prefab: a visible body, a collision capsule, and a head-height check that the camera does not clip at 1.60 m — for when NPCs/pedestrians are wired in (`0.2.0+`), not the `0.1.0` player. Done 2026-11-07: `AGigLineNPCPerson` (C++), ACharacter with capsule half-height 83 cm / total 1.66 m (head at ~1.66 m, so a 1.60 m camera does not clip), the MPFB human on the built-in mesh as the visible body, `AutoPossessAI` for pedestrians; confirmed spawned feet-on-Z-0 and rendered in `Screenshots/review-npc-prefab` (☑ approved 2026-11-07).
- [x] Screenshots use stable camera names (no index prefix), so inserting a shot no longer renumbers/ orphans files; `AGigLineShotActor` + `Screenshots/README.md` updated.

-
- [x] Establish a consistent scale test, named export presets, and repeatable import settings. Scale test = the three-cube calibration scene (`Art/blender/scaletest/`, regenerable via `Tools/scale_test_export.py`); named export preset `ue_metric_v1` (FBX settings in that script); named import preset `ue_metric_v1` (`FbxImportUI` settings in `Tools/ue_scale_test_import.py`). Both scripts are the templates for production asset export/import.
- [A] Collect reference photography for manual façade work. Local only, never committed: `Art/reference/` is gitignored. **72 images in eleven folders**: hero façades to 4k, the El Capitan Theatre exterior series, premiere-night staging, Ovation Hollywood, the north side, and the Lee Drug neighbour. Gaps largely closed by the Flickr/web-search pass: the hero entrance is now documented (three portals with individual short flights — the inherited "eight steps, 12 m wide" is overturned), and the 6806–6822 retail run appears in an oblique 2013 frame. Still missing: a clean isolated frame of the door recess and a night frame of 6840 itself.
- [x] Download reference photography for the two north-side buildings inside the 50 m buffer — TCL Chinese Theatre (OSM way 424105908, 6925 Hollywood Blvd) and Madame Tussaud's (way 424105889, 6933 Hollywood Blvd). Done 2026-11-06 with `Tools/commons_fetch.py` against the Wikimedia Commons API: eleven frames in the local `Art/reference/north-chinese/` and `Art/reference/north-tussauds/`, provenance in each `sidecar.json`, nothing committed.
- [x] Model hero façade for the El Capitan Entertainment Centre site. **Second pass built 2026-11-07** (proportions recalibrated from the 2009 photograph: entablature 3.4 m, parapet 2.2 m, architrave and cornice bands, square pedestals — the first pass had 5.7 m of blank wall above the capitals and read as a warehouse). **First pass built 2026-11-07** (`Tools/hero_facade_build.py` → `Art/blender/hero/hero-facade-2026-11-07.blend` + JSON part report with evidence per part → `Tools/ue_hero_facade_import.py` → `/Game/Hollywood/ElCapitan/SM_HeroFacade`, 1892 tris, 4 materials, placed on the measured building line). Six columns at 4.96 m over the 25.75 m frontage, plinth, three portal flights (5 risers, not the old 8), entablature 2.2 m, parapet 1.6 m with motto band and medallions. **Screenshot approved** (`Screenshots/review-hero-portals`, `review-hero-facade-front/oblique`). Next pass: banner and window placement, then materials.
- [x] Model surrounding block frontage. **Done 2026-11-07, screenshots approved.** The five remaining south-side buildings verified for the block (`Geo/verification/2026-11-06-el-capitan-block.md`) are exported in place from the OSM blockout by `Tools/export_block_frontage.py` -> `Tools/ue_import_block_frontage.py` -> `/Game/Hollywood/Frontage/`, and staged by the demo builder: 6922, 6902, 6838 El Capitan Theatre, 6822 Budget, 6806-6820, 6800 Lee Drug. **Adding them exposed a pre-existing placement bug**: UE south is +Y (the south sidewalk is Y +718..+1447) but the hero facade sat at Y -1450 (north side) and X -12024..-9420, i.e. 26 m east of its own footprint and on the wrong side of the street; the two north-side buildings were likewise on the south side. The hero is now at X -13336 / Y +1307 (inside the frontage gap between 6902 and 6838) and the north buildings are back on the north side (Y -1802..-9431). The sun was raised to pitch -62 so both frontages read instead of one being silhouetted.
- [x] Model simplified background buildings directly across Hollywood Boulevard. Done 2026-11-07, the two in-scope north-side buildings — TCL Chinese Theatre (SM_TCL_Chinese_Theatre) and Madame Tussaud's (SM_Madame_Tussauds) — taken from the verified OSM blockout volumes and exported with `ue_metric_v1`, with a Y-mirror so they land north of Hollywood Blvd across the street from the hero (TCL spans Unreal Y 1802..9431, Tussaud's 1888..7586; road centreline ≈ 0, hero façade at Y −1450). Staged in the DemoMap as `North_TCL_Chinese` / `North_Madame_Tussauds`; demo shot `review-03-demo-north-buildings` captured. Simple flat facade materials (surfaces are the `0.1.4` patch).
- [A] Build sidewalks, roads, and collision meshes. Terrain, road, sidewalks and kerbs exist (`Art/blender/terrain/`, `street/`) and are assembled in `site/site-2026-11-06.blend`; collision and details (crossing markings, kerb radii, aprons) are not built. Ground must follow the DEM: 3.94 m fall along the block, ~2 % crown between the gutters at ±10–11 m from the centreline, north sidewalk higher than south. Kerb height is an unresolved assumption — the DEM does not resolve it (`Geo/verification/2026-11-06-cross-sections.md`).
- [x] Materials and look development for all exported assets. **Done 2026-11-07, screenshots approved.** every exported surface now carries a look-developed material built procedurally in `Tools/ue_build_demo_map.py` (`ensure_material`): base colour with a world-space noise blend between two shades for large-scale variation, plus an explicit roughness and specular. Set is `M_Asphalt` 0.92, `M_Concrete` 0.88, `M_KerbConcrete` 0.85, `M_Ground` 0.98, `M_RoadPaint` 0.62, `M_FacadeStone` 0.72 (hero façade) and `M_Stucco` 0.86 (TCL, Tussaud's), assigned by mesh and by actor label. Materials are rebuilt on every run so a stale asset cannot mask a look change. The richer texture-based pass (baked/procedural brick, brick_facade and seamless_concrete generators) stays in the `0.1.4` façade patch.

-
- [x] First-person movement, mouse look, and Enhanced Input bindings. Implemented 2026-11-07: `AGigLineCharacter` (C++, 1.75 m capsule, 1.60 m eye camera, 4 m/s walk, mouse look in deg/s, jump) as the default pawn, with five actions and an 11-entry context in `/Game/Input` built by `Tools/ue_create_input_assets.py`. **Not yet confirmed interactively** — launch PIE on `Test/ReviewMap` and walk. Screenshot review pending (`Screenshots/README.md`).
- [D] Collision, reset, and pause functionality. Reset (**R**) and pause (**Escape**, a real game pause that releases the cursor) are implemented in `AGigLineCharacter` with `/Game/Input/IA_Reset` and `IA_Pause`. Collision now exists — terrain, road and sidewalks import as complex-as-simple, so a simple hull cannot ramp over the kerbs. **Not verified by hand**: walk, reset and pause need a human at the keyboard. No pause menu widget yet, only the pause itself.
- [x] Build the walkable demo level: terrain, street, and hero facade assembled into one map with a start point on the north sidewalk, so the demo is something a player can walk rather than a review staging. **Built 2026-11-07** by `Tools/ue_build_demo_map.py` → `/Game/Hollywood/DemoMap`: sun/sky, `Hero_Facade`, six site meshes imported with collision (`Terrain_DEM`, `Road_Hollywood`, both sidewalks and both kerbs), and a `Demo_PlayerStart` on the north sidewalk 20 m back from the frontage. Demo views in `Screenshots/demo/` re-rendered and ☑ approved 2026-11-07.
- [x] Walkable sidewalks and a designated street crossing. Crossing chosen: mid-block signalised crossing, OSM way 385648319, at 130 m along the block (`Geo/verification/2026-11-06-street-profile.md`). Done 2026-11-07: continental zebra markings (0.5 m bars / 0.5 m gaps, 3 m band) at all three signalised crossings, no collision on the paint; kerbs were already flushed at the crossings. Enablers found on the way: the street surfaces were 100 % down-facing (invisible in engine) — winding flipped; the terrain buried the street — 10.7 m corridor cut around the centreline (sidewalks cover the transition, walk-check 0 holes); LFS-lockable `.blend`/`.umap` check out read-only — builders now chmod before saving and fail loudly. Screenshot ☑ approved 2026-11-07 (`Screenshots/demo/review-demo-crossing`); the corridor renders near-black in shadow — that was the **Fixed daytime lighting** item, now also done.
- [x] Fixed daytime lighting and basic ambience. **Done 2026-11-07, screenshots approved.** Demo map now has a fixed daytime rig in `Tools/ue_build_demo_map.py`: sun pitch −50 / yaw 120 (intensity 4, warm 255/245/230, atmosphere sun light), sky light 2.6 with real-time capture, sky atmosphere, height fog (density 0.008), and a manual-exposure post-process volume (min = max brightness 1.0) so a shot cannot wash out or crush to black. Two root causes found while doing it: (a) **Blender flat diffuse colours do not survive the FBX→UE import** — every site mesh arrived white and the terrain arrived with `WorldGridMaterial`, which is what actually made the scene look blown out; explicit `M_Asphalt` / `M_Concrete` / `M_Ground` / `M_RoadPaint` materials are now created and assigned in the demo builder. (b) only **one of the three crossings** was reaching the game: each band was its own object and Blender renamed the duplicates `.001`/`.002`, which site assembly skips; all bands are now one `Crossing_Markings` object. Demo cameras also fixed: street-level sat inside the façade body, and the crossing camera aimed at the wrong crossing (s=36.6 instead of the designated s=130.1 at UE X −14956). Lighting is dynamic-only (`r.AllowStaticLighting=False`, all lights Movable) so the editor's "LIGHTING NEEDS TO BE REBUILT" warning no longer fires. All four demo views approved by the owner.
- [x] Geographic attribution display ("© OpenStreetMap contributors" + license link). Done 2026-11-07: `AGigLineHUD` (C++) draws the credit line and the licence URL (`© OpenStreetMap contributors` / `Data © OpenStreetMap contributors, ODbL 1.0 — openstreetmap.org/copyright`) in the bottom-left of every frame, wired through `AGigLineGameModeBase::HUDClass`. It is a plain `AHUD::DrawText`, so no UMG widget asset can be dropped from a cook. `AGigLineShotActor` now requests screenshots with the UI shown, so the attribution is visible in every image under `Screenshots/` and the obligation is provable, not just documented.
-
-### Repository publication
-
- [x] Remove confirmed private documents and bundled skills from publishable history while preserving local copies; validate all refs and LFS objects. Rewritten 2026-11-07; original history is in a separate private local backup.
- [x] Scan all reachable Git history and the publication changes with Gitleaks 8.28.0. Removed an Android File Server security token from history and disabled the unused server; the rescans found no leaks.
- [x] Review Unreal asset provenance via the generation/import scripts and inspect all 18 reachable Unreal asset versions for recognizable private-reference paths. No such paths were found; this is not a full binary-content audit.
- [x] Review OSM source distribution notices: original data retains attribution and licence metadata, and the repository links directly to ODbL 1.0.
- [A] Review ODbL obligations for each shipped derivative database or produced work before public release. In-game attribution display is implemented (`AGigLineHUD`, visible in every screenshot); the remaining question is the ODbL "derivative database" posture for a shipped build that contains OSM-derived geometry.
- [x] Validate Gitea LFS support. The first push succeeded on 2026-11-07; a separate clone fetched all 26 historical LFS objects and passed integrity checks.
- [x] Commit and review the publication preparation changes before pushing. Initial publication commit: `101db3f`.

-### Release checks
-
- [ ] Player can traverse both sides of the demo without falling through geometry. Blender pre-check passes: 0 raycast holes along both sidewalks and the designated crossing; worst seam step 15.8 cm at the sidewalk's outer edge (`Art/blender/README.md`). Engine traversal still to be tested.
- [ ] Building placement, street scale, and site identity checked against references.
- [ ] No blocking collision or packaging defects.

- [ ] Fresh project checkout builds with the documented external engine installation.
- [ ] Package Linux build with documented controls.
- [ ] Tag `v0.1.0` and write `CHANGELOG.md` entry; then remove this section.

+"""Pure-Python uinput driver to inject OS-level keyboard and mouse input.
+
+This is a small, dependency-free input driver used by the demo QA harness
+(`Tools/input_test.py`) to prove whether OS input actually reaches the game.
+It talks to ``/dev/uinput`` directly through ``ctypes``, so it creates a real
+virtual input device that the kernel and the desktop session (X11 or Wayland)
+treat as genuine hardware. The game cannot tell simulated input from a real
+keyboard/mouse.
+
+No third-party packages are required. ``/dev/uinput`` must be writable by the
+calling user (on this machine the system ACL grants `zwitschi` rw; if it is
+not, add a udev rule or run as a user in the `input` group).
+
+Usage
+-----
+    from input_emulation import InputDevice
+
+    with InputDevice() as dev:
+        dev.key('w')            # press and release W -> types 'w'? no: key code 17
+        dev.hold('w', 0.5)      # hold W for half a second (run forward)
+        dev.move(120, 0)        # nudge the mouse +120 px on X (look right)
+
+All calls log using Python's `logging` module so a scripted test can show the
+exact injection timeline next to the game log.
+
+Design notes
+------------
+* Uses the newer ``UI_DEV_SETUP`` ioctl with a ``struct uinput_setup``, falling
+  back to the legacy ``write(struct uinput_user_dev)`` method if the kernel
+  rejects it (very old kernels). On this kernel the setup ioctl path is used.
+* The device exposes EV_KEY (keyboard), EV_REL (relative mouse) and
+  EV_SYN (synchronisation). It does not declare an absolute axis, so it is
+  treated as a relative device and the desktop does not try to give it an
+  on-screen pointer role.
+* A single device with both keys and relative axes is created; for a game this
+  is fine. If a separate gamepad (EV_ABS/EV_FF) is wanted later, extend this
+  file with a second device class that also sets ABS bits.

+#!/usr/bin/env python3
+"""QA harness: inject scripted OS-level keyboard/mouse input at the running game.
+
+This is the tool that proves whether OS input actually reaches the game. It uses
+`Tools/input_emulation.py` to create a virtual input device directly on
+`/dev/uinput`, so a focused game window receives the injected keys and mouse
+movement as genuine hardware input — indistinguishable from a real keyboard.
+
+Typical workflow
+----------------
+The game must already be running and focused (it will not be launched here; the
+user brings up the window). Run this script from a separate terminal:
+
+    python3 Tools/input_test.py --sequence move:2,look:3,jump:1,reset:1,pause:1
+
+It prints a per-step timeline (seconds) to stdout, which you can compare against
+the `GigLine IN:` rows in the game's `Saved/Logs`. If the game log shows
+`MoveForward fired` / `Look fired` for the injected steps, OS input is reaching
+the pawn and the remaining problem is not input delivery.
+
+Usage
+-----
+    python3 Tools/input_test.py                       # default smoke sequence
+    python3 Tools/input_test.py --sequence move:2,look:3,jump:1,reset:1,pause:1
+    python3 Tools/input_test.py --device /dev/uinput  --name "GigLine QA Input"
+
+Steps supported in `--sequence` (comma-separated, `name:count`):
+    move    hold W forward (each unit = ~0.5 s)
+    back    hold S
+    strafe  hold D
+    left    hold A
+    look    nudge mouse right (rotate camera)
+    jump    press Space
+    reset   press R
+    pause   press Escape
+    click   left mouse click
+
+Design
+------
+* The device is kept open for the whole run and destroyed on exit (context
+  manager), so nothing persists after the harness quits.
+* Each step logs an absolute timestamp so you can line it up with the game log
+  wall-clock times (the game logs to `Saved/Logs/GigLine.log` with the same
+  system clock).
+* No third-party packages: only the Python standard library.

GigLine and GigLineEditor now both compile clean. - tools: OS-level uinput input harness (input_emulation.py + input_test.py) and run_pie.sh for PIE isolation; document the PIE-vs-packaged input test in Docs/build.md.

zwitschi	52b1212cf3	qa: make the demo walkable — terrain collision root cause, spawn, scripted QA The reported fall-through was a misdiagnosis: the player never fell. The imported Terrain_DEM had only a bounding-box simple collision proxy, so a downward trace anywhere in the block hit the terrain at Z 819 (the mesh bbox max) and the street sat under an invisible 8 m lid. Standing on that box looked plausible, which is why it read as working. - add UGigLineAssetTools (C++): force CTF_UseComplexAsSimple on a static mesh. UE 5.8 dropped bUseComplexAsSimpleCollision and Python cannot set the flag; the builder also saves the asset, since the flag lives there and a map-only save silently reverts it. - spawn (-13336, -1150, 600): inside the carved corridor (the cut is a 10.7 m half-width around the road centreline), lands on the road at 456. - fix ResetToStart returning to the mid-air PlayerStart captured in BeginPlay: StartLocation is now captured on the first grounded frame. - HighResShot 1280x720 instead of "1280 720", which is a multiplier. - add -qaselftest: scripted walk/reset/pause on a core ticker plus a swept ground transect. Results: walk 746 cm/2 s with Z steady, reset 0 cm from spawn, pause/unpause 1/0, transect 84 samples 0 holes. - rebase onto main, keeping the frontage materials and placement fixes.	2026-11-08 11:56:19 +01:00
