 These are presentation changes. Workflow Session and durable Agent identities,
 credential scopes, refresh behavior, and mutation handling keep their existing
 contracts. Model-reported progress remains informational.
+
+Each selected Project/workspace has its own keyboard-accessible disclosure below
+its Runner. Closing it hides that workspace's Sessions without clearing the
+selected Session or composer; its preference survives refresh. Selecting another
+workspace opens its Session list.
+
+At widths of 1280px and above, Context docks beside a narrower conversation, with
+more room for readable status and progress. Its Overview starts with the latest
+retained Agent-authored message. Resolution text is also visible directly below
+the original message, rather than only in a tooltip.
+
+Project search continues to query authorized Projects by name, id, Runner, or
+workspace path. Separate searches filter the loaded Sessions by title/id/lifecycle
+and retained messages by body, resolution, id, or author Session. Match counts
+refer only to loaded results; these controls do not search unretained history or
+host transcripts and do not change the selected Session.
+
+The Session board is not a mirrored host chat transcript. An observed ACK records
+an explicit model-context acknowledgement, not a reply, read receipt, or completed
+work. Model replies appear only when explicitly posted to the Session; reported
+progress is separately labeled as informational. An empty latest-message card
+means no Agent message exists in the currently retained window.
