Scopes Follow Ups

Will elaborate this, but want to document so we don't forget:

#1492, #1493, and #1511 addressed some scope issues. We still need to sort out:

- Scope naming inconsistencies (pluralization, action names)

- Scope requirement inconsistencies (all actions should use the same scopes across models)

- Agent deletion alignment (currently used name, which is not unique)

No files, tests, or entry points are listed in this issue; it only references #1492, #1493, and #1511. Start by reading those issues to find where scope names, action requirements, and agent deletion are currently defined. Then inspect the corresponding implementation areas in the codebase and scope checks to reconcile naming/action consistency and ensure agent deletion uses a unique identifier. Done means those three mismatch areas are resolved consistently across models.
