+  fixed `/api/works/data-service` Host routes, route precedence before the
+  Works catch-all, and focused tests; no preview/Pi/Renderer credential or
+  unrelated transport logic was added. The foreign ML-03 task record was
+  deleted from this coordinator after cherry-pick; the source worktree retains
+  its own record. The ML-04 frontier is this integrated commit plus the

 ## Follow-ups
 
-- ML-02 identity choice and legacy/independent-copy UX is integrated. ML-03
-  must use
-  `requireActiveRealProjectWithIdentity()` for all Data Service callers.
+- ML-02 identity choice and legacy/independent-copy UX plus ML-03 Main Data
+  Service are integrated. ML-04 must consume the `DataServiceOperations` seam
+  from the recorded ML-03 frontier and preserve its active-project identity
+  and trusted project-path constraints.
 - The broader ML-00 through ML-09 coordinator task remains in progress; this
   record does not claim full client-suite, build, review, or release proof.
