+# Explicit unread inbox on startup and resume
+
+Legacy `torch_read_messages` defaults to the oldest 100 historical messages.
+Observed native inboxes exceeded 100 unread messages during fleet supervision.
+Launch/resume now explicitly requests the bound identity's unread inbox with a
+limit of 1000 and explains chronological order, potential overflow and deliberate
+acknowledgements. This uses the existing tool without changing its API contract.
+
+This mitigation does not implement pagination, newest-first history, coherent
+cross-query observation, or complete overflow detection. Those remain in the
+existing unread-first inbox task. A result of 1000 is explicitly uncertain,
+not a complete-inbox claim. No permissions follow from reading a message.
+
+SCN-fleet-startup-inbox exercises the actual fresh/resume launch arguments and
+registered identity-bound inbox tool against messages beyond the default page.
