<title>the per-brain mailbox</title>
<desc>A flow between agents. Agent A, on mission X, finds a defect outside its own scope and writes a letter into .m1nd/inbox.jsonl, an append-only file on disk beside the code. Agent B, days later, sweeps that mailbox over CLI or REST, never inside the query loop, and its mission starts already knowing about the defect.</desc>
