+- **Commit/build discipline (2026-11-03):** commit each coherent verified change as it lands, not
+  only at milestone end, and push shareable commits. Every major, minor and patch version requires
+  a `CHANGELOG.md` entry, a local `tools/build_releases.sh` build and artifact/checksum
+  verification before tagging. CI tag builds are the second gate, not a substitute.
 - **Gaussian splatting / photo-derived maps (unversioned local track):** expanded in
   `TODO.md` "Gaussian splatting evaluation". Accepted photo channels are team captures,
