+The initial read includes the bounded `unfinished_delegations` projection and
+`read_complete` flag. For an admitted normal work Turn with a large, complete
+agenda and a matching required Manager Inbox read, the initial view keeps the
+incoming and outgoing request counts, scan status and required command. The
+required read delivers the rows and their guidance. The original rows remain
+available from the same capture. Adoption and
+queued returns are intermediate states. Read the full current request before
+assessing, executing or returning it. Use the existing scoped request and
+consumption routes for those actions.
 It also exposes existing outcome material addresses and the current settlement
 plan's obligations, including unknown step fields. Only attachments explicitly
 marked `required=false` defer their guidance/templates; their routes stay visible
