description	USE FOR: MUST LOAD after sends or live mailbox/session work: passive waits, exact replies, bounded status, stale/dead-letter state, and pane hints. DO NOT USE FOR: first-contact sends, polling loops, or topology audits.

postman-session-operator

MUST load after sending or live mailbox/session work; first contact uses postman-send-message.

1. USE FOR / Procedure

Do not poll. After sends or delegated work, wait passively for notification, exact reply, timeout/watchdog boundary, explicit user status request, or concrete delivery trouble.
pop is only for explicit notification/current evidence of mail; never run repeated pop or sleep/pop loops.
Bounded status is only for explicit user status request, watchdog boundary, or concrete delivery trouble; never use status as a heartbeat.
tmux-a2a-postman inspect-message --id <message_id> is read-only historical lookup. Use --path for the stored Markdown path and --body for sender-authored body text.
After every successful pop with status=message, read the complete archived Markdown body before any handling, routing, reply, status decision, or no-action or no-op decision. messageType: ping, replyPolicy: none, and other metadata do not allow skipping the body. truncated command output does not count as a complete read.
Both send-heredoc and pop output a submit_path field (daemon-submit or post) identifying whether daemon mediation was used or bypassed by direct filesystem access. This applies to all output including empty pop results. Use submit_path to audit fallback behavior.
Filling an input request closes transport, not task acceptance. After any exact reply, check send JSON fill, required_input, and notice. DONE/completion or BLOCKED/task-acceptance replies require Task artifact: <artifact-reference>, Original checklist: PASS, evidence, and Remaining blockers: none. Use BLOCKED with Original checklist: FAIL.
Receivers verify checklist status, durable references, evidence, and blockers before relaying, approving, or closing work.
Pane ids require exact tmux verification; missing panes are stale evidence. Dead letters, missing routes, or stale topology go to postman-config-auditor. More detail: Session Flow.
