 #### Reference
 
-Implementations receive the final destination after naming and collision handling. Return that directory from `create`;
-`list` must report only directories the strategy owns, plus any repository roots. Core owns inventory and startup commands.
+Implementations receive a suggested destination after naming and collision handling. Return the actual directory from
+`create`; it may differ when a backend requires its own layout. OpenCode resolves the returned path and uses it for
+inventory, startup commands, and the API result. The returned directory must exist.
+
+Strategies choosing another destination handle naming collisions there. OpenCode still creates the suggested parent
+directory before calling the strategy. `list` must report only directories the strategy owns, plus any repository roots.
