licensing policy. ROADMAP 0.1.0 environment tasks marked to match verified state.

+# Tools
+
+Repeatable import/export and processing helpers. Anything that was done twice by hand belongs here.
+
+## Conventions
+
+- One script, one job. No interactive prompts; every input is an argument.
+- Each script documents its input format, output format, and the exact tool version it was tested with.
+- Blender scripts run headless (`blender --background --python`), so they can be re-run for a regression check.
+- No credentials, no absolute machine paths, no writes outside the project by default.
+- A script that produces game content logs what it produced, so `Game/Content` can be audited against it.
+
+## Planned helpers
+
+- Blender export preset runner (named presets, metric scale assertion)
+- Blender→Unreal scale test (export a known-size cube, verify 100× conversion)
+- OSM extract fetch and manifest writer (records date, bounds, checksum)
+- QGIS processing steps as batch scripts, so the geo cleanup is reproducible rather than GUI-only
