+## [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.
