 ### Permissive route
 
 A lower-friction incorporation path available when the repo posture allows it.
+Even on a permissive route, a donor may still require clean-room handling if its
+product identity (vocabulary, taxonomy, mascot, or distinctive workflow) is too
+strong to import literally. This is a **permissive clean-room reservoir**:
+legally reusable, but product-identity constrained.
 
 ### Restrictive route
 
 A constrained path such as clean-room, sidecar, protocol boundary,
 reference-only use, pattern-only use, donor-only deferral, or explicit
-non-integration.
+non-integration. Required for copyleft, source-available, non-free, or custom
+licenses. This is a **restrictive clean-room reservoir**: legal or custody
+constraints block direct runtime import.
+
+### No-grant route
+
+When no explicit repo-root license grant is present, default copyright applies
+and donor text/code cannot be copied. If the behavior is valuable and
+describable generically, route through clean-room or pattern-only handling
+rather than hard-omitting. This is a **no-grant clean-room reservoir**.
+Do not treat missing license as an automatic exclusion.
