+## Version Control & Safety Guidelines
+- **Coordinate before forceful changes**: Never rewrite history on shared branches. Use dedicated
+  feature/bugfix branches (see `docs/public/developer/git-workflow.md`) and keep `develop/master`
+  clean.
+- **Back up ROMs and assets**: Treat sample ROMs, palettes, and project files as irreplaceable. Work
+  on copies, and enable the editor’s automatic backup setting before testing risky changes.
+- **Run scripts/verify-build-environment.* after pulling significant build changes** to avoid
+  drifting tooling setups.
+- **Document risky operations**: When touching migrations, asset packers, or scripts that modify
+  files in bulk, add notes under `docs/internal/roadmaps/` or `blueprints/` so others understand the
+  impact.
+- **Use the coordination board** for any change that affects multiple personas or large parts of the
+  tree; log blockers and handoffs to reduce conflicting edits.
