Fixes #19429

Limit single-session delete to the canvas owner or the session's creator and answer "shared session is readonly" otherwise, mirroring the Go rule in internal/service/agent_sessions.go (DeleteAgentSessionItem).

Tests: 3 new route-level unit tests in test/testcases/restful_api/test_agent_session_delete_unit.py - the team-member denial test fails on main; the owner delete and member-deleting-own-session tests pass on both.

…delete

DELETE /agents/<agent_id>/sessions/<session_id> only required canvas
access, which team members hold on a shared agent, so any team member
could delete the owner's or another member's sessions. The batch delete
route already restricts deletion to the canvas owner, and the Go API
enforces the same readonly rule for the single-session route
(internal/service/agent_sessions.go DeleteAgentSessionItem).

Limit single-session delete to the canvas owner or the session's
creator, and answer "shared session is readonly" otherwise.

Add route-level unit tests for the team-member denial, the owner delete,
and a member deleting their own session.

📝 Walkthrough

Walkthrough

The session deletion endpoint now permits deletion only for the canvas owner or session creator. Unit tests cover rejected team members, canvas owners, and session creators.

Changes

Session deletion authorization

Layer / File(s) Summary
Enforce deletion ownership
api/apps/restful_apis/agent_api.py
The endpoint returns "shared session is readonly" when the caller is neither the canvas owner nor the session creator.
Validate deletion authorization
test/testcases/restful_api/test_agent_session_delete_unit.py
The isolated tests verify rejection for other team members and successful deletion for canvas owners and session creators.

Session deletion now permits the canvas owner or session creator and rejects other shared-session members without deleting the session. The covered authorization cases indicate no remaining merge-blocking risk.

Done - the stub now tracks delete_by_id calls and the denial test asserts the session was not deleted.
