(b) _clone_intake_scope dedupes slugs by git_url before cloning. A multi-project scope can list several projects pointing at one repo (a monorepo's cell-projects share a git_url); cloning each produced redundant identical workspaces. Mirrors CI-watch's per-git_url dedupe: keep the first slug per non-empty git_url; a project with no/empty git_url is never collapsed onto another so distinct local repos still clone. The dedupe is a pure static helper (_dedupe_slugs_by_git_url) with unit coverage. --------- Co-authored-by: Backend Developer 2 <be-dev-2@roboco.tech> Co-authored-by: Backend Documenter <be-doc@roboco.tech> Co-authored-by: Backend Developer 1 <be-dev-1@roboco.tech> Co-authored-by: Renn F <rennf93@users.noreply.github.com>

+Exercises both the scheduled audit trigger path and the reactive alert producer
+path end-to-end, verifying they result in auditor-targeted work.
+
+- Scheduled path: an in-process orchestrator instance polls the real e2e API,
+  sees recent delivery activity, and calls ``spawn_agent(agent_id="auditor")``
+  with the scheduled sweep prompt.
+- Reactive path: a real QA-fail POST creates an ``ALERT`` notification addressed
+  to the auditor in the DB; the orchestrator's audit dispatcher fetches that
+  alert and calls ``spawn_agent(agent_id="auditor")`` with the quality-alert
+  prompt.
+
+No real auditor container is spawned — ``spawn_agent`` is stubbed so the test
+asserts on the dispatch decision, not the LLM runtime.
