+## Legacy RPC Install Semantics
+
+The dedicated `steam_workshop` module still uses the legacy `steam_workshop` agent RPC for installs.
+
+Current rule:
+
+- if `config/filepath` is blank, the Panel passes a blank `config_file_path`
+- agents must skip the generated config-file editing block entirely
+- post-install scripts still run
+- `WorkshopModsInfo` still records installed items
+- uninstall can rely on `WorkshopModsInfo` when no config file is managed
+
+This keeps advanced regex editing available without forcing it for simple Arma/DayZ-style `@mod` installs.

 ## Security Concerns
 
 - should not be duplicated under `addonsmanager`
