 - [x] Player can traverse both sides of the demo without falling through geometry. **Verified 2026-11-08:** Blender pre-check plus an in-engine swept transect (`-qaselftest`) over the north sidewalk, carriageway and south sidewalk from X -14900 to -9420 — 84 samples, 0 holes, ground Z 317..395 (sidewalk 395, road 366, south walk 317). The player spawns at Z 456 and stays there for the whole run (`fall=0`, single Z).
 - [x] Building placement, street scale, and site identity checked against references. **Done 2026-11-08:** rendered current DemoMap content, probed world-space geometry (road 24.3 m vs ref 20.9–25.9 m; sidewalk centreline offsets 12.5/13.2 vs ref 12.6/13.6 m; hero frontage 26.0 m, setback ~13 m vs ref 25.75/14.5 m; frontage + north buildings in verified OSM positions), recorded PASS + deliberate deviations (flat blockout surfaces → `0.1.4`, kerb upstand → `0.1.1`, kerb-flush ramps → `0.1.1`) in `Docs/release-checks.md`, and fixed the mis-aimed north-buildings camera (was 9.5 km west → 85% sky; now frames the buildings). Final human verdict pending on `Screenshots/demo/*`.
-- [A] No blocking collision or packaging defects. Extend the `-qaselftest` transect with seam samples (road↔kerb↔sidewalk boundaries at Y −1382/−1053/+718/+1047 and the crossing edges) and a horizontal walk-height probe for invisible walls / blocking meshes; run on the packaged build and record evidence in `Docs/release-checks.md`.
+- [x] No blocking collision or packaging defects. **Done 2026-11-08:** extended `-qaselftest` — transect now 1456 samples / 16 rows including the kerb/road/sidewalk seam Ys (0 holes), plus a ground-referenced 30 m wall probe (0/35 blocking hits; no invisible walls). Walk/reset/pause all PASS on the packaged build; `GigLineShotActor` now skips under `-qaselftest`. Evidence in `Docs/release-checks.md` §`0.1.0` audit note.
 - [ ] Remove TEMP QA diagnostics (`GigLine SIM` / `GigLine GROUND` log lines and the settle-timer log) from `GigLineCharacter.cpp` before the release tag, or gate them behind a cvar.
 - [ ] 60 FPS at 1440p on the dev workstation (Bazzite, Ryzen 7 7700X, 64 GB RAM, RTX 5070 Ti 16 GB) using a documented quality preset; record upscaling state; report performance without frame generation.
 - [ ] Fresh project checkout builds with the documented external engine installation.
