| 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-4 | ODbL derivative-database posture for shipped builds is open | Medium | In-game attribution is done; legal review of shipped-DB obligations needed before public release.
| 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.
