+This subprocess L2 landed at `seaweed_block@bdd56c7` and was upgraded at

+pre-writing lifecycle store internals:
 
 - real `cmd/blockmaster` with `--lifecycle-store`;
+- `--lifecycle-placement-seed <json>` imports placement intent through the daemon entry point;
 - real `cmd/blockvolume` subscribing to assignment stream;
 - only r2 observed, so legacy topology controller cannot satisfy RF=2 by itself;
 - lifecycle product loop publishes the verified existing-r2 placement;
