+### Agent state (row 59, #1548)
+
+For a human or reader session, `agents` derives each held role's state from
+records the bus already keeps. Nothing new is written and no schema changed.
+
+- `working` is `{messages, since}` or null: messages to the role that the
+  current holder received and hasn't marked read, and when the oldest was
+  received. The runner receives a batch, takes one turn per message, replies
+  and marks it read, so working means a turn is under way or queued.
+- `inputNeeded` lists the role's open decisions routed to the human, gated
+  first and then oldest, as the Inbox orders them. Each item is
+  `{id, question, class, blocking, task_ref, at}`. Seen is still open.
+- `state` is `working` when `working` is set, else `waiting` when
+  `inputNeeded` is nonempty, else `idle`. Working wins over waiting, as on
+  the control board.
+
+Why the bus and not a seat-to-role map: the business file's `holder` is a
+display name, and the claim's holder is a run, not a seat, so no committed
+data joins a seat to a role. The bus already has the claim, the deliveries
+and the decisions.
+
+Limits: a message routed but not yet received shows idle. A reply that fails
+for a reason other than a gone session leaves its message unread, so the role
+stays working; `since` shows how long. No error or offline state is derived.
+A new holder doesn't inherit the previous holder's unread deliveries;
+decisions stay with the role. Unheld and released roles aren't listed.
+
 Unknown keys, roles, references, actions and verbs refuse. If writing refusal
 evidence fails, the caller receives the static `storage-unavailable` code. `human` is the reserved
 recipient. Message classes are REQUEST, ASSIGNMENT, REVIEW-REQUEST, REVIEW-RESULT,
