R2 review transport receipt

One actionable agent-send.sh request sent from dragon-lin:darkwing to default socket =filbert, pointing to 2026-09-07_tmux-r2-review-request.md and the separate frozen r2 export. All seven export hashes verified immediately before send.

Exit 2: message-correlated editor evidence unavailable within observation window. Delivery unconfirmed, no acknowledgement claimed. Do not blindly resend. Expected reply/artifact: docs/plans/reviews/2026-09-07_tmux-r2-verdict.md. Darkwing owns reconciliation when a reply or artifact arrives. No watch/timer registered. Other authorized wave tasks may proceed independently, but no push before review and live verification.
