+
+- All six `0.1.0` release checks pass and are recorded in `Docs/release-checks.md`:
+  traversal (seam transect 0 holes), placement vs references, collision+packaging
+  (wall probe 0/35), 60 fps at 1440p (2.42 ms avg; TSR on, VSync off, no FG),
+  fresh-checkout build, packaged Linux build with controls shown in-game.
+- `CHANGELOG.md` gets the `0.1.0` entry; the completed `0.1.0` section was removed
+  from `TODO.md` (goal stays in `ROADMAP.md`); tag `v0.1.0` cut on `main`.
+- Owner approved the regenerated screenshot set (PR #15) on 2026-11-08.
+- THIRD_PARTY_NOTICES switched to checkbox statuses (`[x]`/`[P]`/`[ ]`); all tools
+  incl. Blosm, QGIS and Git LFS are now verified as tool-only.
+- Next work: the `0.1.1` collision-detail patch (sidewalk outer edge 15.8 cm step,
+  crossing ramp gradient 10 %, kerb height assumption, traversal regression).
