+## [0.1.1] — 2026-11-08
+
+Collision-fidelity patch. No new scope: street geometry corrections and the QA
+tooling that measures them.
+
+### Fixed
+
+- **Sidewalk outer edge ledge.** The sidewalk stood the full 0.15 m kerb height
+  above the DEM at both edges, leaving a 15.8 cm lip where the walk route crossed
+  from terrain onto the south sidewalk. The upstand now tapers from full at the
+  road-side edge to zero at the building-side edge; the north route's worst step
+  fell from 15.1 cm to 6.9 cm.
+- **Crossing ramps too steep.** The kerb-flush run was a fixed 1.5 m, giving
+  ~8.7 % (measured 10–13 cm over 1.5 m). The run is now derived from a target
+  grade (`--max-ramp-grade`, default 8 % ⇒ 1.63 m); the crossing steps 3.4 cm at
+  0.25 m sampling.
+
+### Added
+
+- **Walk pre-check improvements** (`Art/blender/site/site_assembly.py`): sampling
+  coverage is independent of `--sample` (it previously shrank the route), and the
+  report now prints the grade and the arc-length/offset **location** of the worst
+  step, so a step can be located rather than guessed.
+
+### Changed
+
+- **Kerb height recorded as final** at 0.15 m modelled / 0.13 m as built — a
+  standard 6 in LA kerb; neither the 3DEP DEM nor the reference photography can
+  resolve it further (±2 cm), which is far below the character's 45 cm step
+  height.
+
+### Verified
+
+- Site meshes rebuilt and re-imported (7/7, collision flags intact), DemoMap
+  rebuilt, packaged Development build `EXIT=0`.
+- `-qaselftest` on the packaged build: walk 761 cm in 2 s at steady Z 456, reset
+  0 cm, pause/unpause, transect 1456 samples across 16 rows / **0 holes**, wall
+  probe **0/35** blocking hits.
+
+### Known limitations
+
+- One residual **13.4 cm surface step at s≈198 m** on the south sidewalk (8.0 cm
+  at s≈251 m north). It is not a gap and is below the 45 cm `MaxStepHeight`, so it
+  does not block traversal; the cause is a sidewalk-strip discontinuity near a
+  centreline vertex, recorded in `Art/blender/README.md` as a smoothness
+  refinement.
+- Kerb radii at junctions, driveway aprons, drainage inlets and pavement joints
+  remain unmodelled (unchanged from `0.1.0`).
+
+Nothing yet.
