+  (`feat(coding): add preview data runtime session`), with no cherry-pick
+  conflict. The delivered scope is limited to the Main-owned ephemeral
+  preview session manager, exact `/api/runtime/data/v1` data-only routes,
+  early route precedence, trusted Data Service forwarding, lifecycle
+  invalidation wiring, and focused loopback coverage; ML-06 pre-document
+  injection was not included. The foreign ML-05 task record was removed from
+  this coordinator after cherry-pick; the source record remains in
+  `D:\Datas\OthersProjects\makelore-ml05-preview-data-session-5c8e2a71`.

 ## Follow-ups
 
-- ML-02 identity choice and legacy/independent-copy UX plus ML-03 Main Data
-  Service and ML-04 Pi Data Service tools are integrated. ML-04 consumed the
-  `DataServiceOperations` seam from the recorded ML-03 frontier and preserves
-  its active-project identity and trusted project-path constraints.

   record does not claim full client-suite, build, review, or release proof.
