 ## Result
 
-- Status: Pending execution.
+- Status: Accepted.
-- TDD plan: To be filled during execution.
+- TDD plan:
-- Red evidence: To be filled during execution.
+  - Add integration coverage for site-config version lifecycle and editor restrictions in `apps/backend/tests/integration/test_auth_authorization_public_api.py`.
-- Green evidence: To be filled during execution.
+  - Add dedicated audit-event regression in `apps/backend/tests/integration/test_script_config_audit.py`.
-- Refactor notes: To be filled during execution.
+- Red evidence:
-- Verification output: To be filled during execution.
+  - Not re-creatable from current branch state because implementation already advanced before this pass; existing pre-existing tests were updated to enforce denial behavior, and the audit test was added as a green-path regression.
+- Green evidence:
+  - `pnpm -C apps/frontend run test:ui`
+  - `pnpm -C apps/frontend run typecheck`
+  - `python3 -m py_compile` for changed backend integration + application code (`site_config.py`, `repositories.py`, `schema.py`, `test_script_config_audit.py`) passed.
+- Refactor notes:
+  - Fixed frontend active-version derivation to rely on `version.status === "ACTIVE"` instead of parent `site.active_script_config_version_id` to avoid stale UI after mutation.
+  - Added explicit script config version audit event table and repository (`script_config_version_events`) and wired `CREATE/ACTIVATE/ROLLBACK` events in application-layer operations.
+  - Route handlers now pass `current_user` into config version activation/rollback handlers to persist actor in audit payload.
+- Verification output:
+  - `python3 -m unittest discover -s /Users/gavrilovdev/tmp/pupline/apps/backend/tests/integration` currently fails at import time (`fastapi`, `pydantic`) due missing backend dependencies in environment.
+  - The same backend suite could not be fully validated here without dependency installation.
