The decisive clamp: zero linear and angular velocity every frame for two seconds. t=0.25 Z=3220 vZ=0 | t=0.75 Z=3683 vZ=0 | t=1.25 Z=4197 vZ=0 It rises at ~1200 cm/s with velocity pinned to zero, so this is not a force, an impulse, or a bad initial state - all of those the clamp would have removed. Something calls a transform setter on the vehicle every frame. Our own source contains exactly one direct transform write outside the character (the shot actor's camera), so the writer is engine-side: the Chaos vehicle component driving UpdatedComponent from a vehicle state that was never created, or a skeletal-mesh transform update. Also diffed the two maps, since the pawn works in ReviewMap and not in DemoMap: kill_z, gravity, lights and partitioning are identical; DemoMap adds 593 static mesh actors, a height fog and a post-process volume, ReviewMap adds a shot actor and the character. Nothing in either list can write a transform, so the map difference is not in its actors or settings.
Gig Line
A Linux-first Unreal Engine game about walking and driving through a real city. The first release, 0.1.0, is a walkable exterior demo around 6840 Hollywood Blvd / El Capitan Entertainment Centre, covering the south-side frontage between Highland Avenue and Orange Drive plus the north-side frontage within 50 m of the boulevard.
Status
0.1.0 is in progress. The workstation, engine, geo pipeline and project bootstrap are done and verified; a walkable DemoMap exists with terrain, street, sidewalks, kerbs and the hero façade placed from measured coordinates. Façades are still blockouts, and materials are flat colours — both are planned patches.
Current tasks are in TODO.md and the development plan is in ROADMAP.md; what was learned the hard way is in MEMORY.md.

Getting started
git lfs install # required: content, images, audio, and geo files are LFS-tracked
git lfs pull
Tools/check-lfs.sh # verifies the lfs filter is active and files are stored as pointers
The engine is installed outside the repository and pinned in Docs/toolchain.md. Setup is in Docs/setup.md; building and the content pipeline are in Docs/build.md.
