# P5B Execution Plan 1. Add config normalization for `nativeRoadPackage`, migrate two supported configs and the template. 2. Add the tested ZIP importer with bounded extraction, root-flat/path/symlink validation, SHA cache and manifest/area validation. 3. Route Blender, preview traffic, stage manifests and diagnostics through the imported descriptor. 4. Delete compiler CLI/compile production paths and package dependency; replace their tests with ZIP fixture and negative importer tests. 5. Update docs/specs, run native/legacy unit suites, build two exported packages, then run Blender parity. Rollback: restore the old compiler dependency and native compile path in one revert; ZIP exports remain non-destructive standalone files.
