- chat send and listener-smoke accept --session; defaults remain File Transfer Assistant.
- Reject existing drafts, reacquire the send control after input changes, and require a
fresh message fingerprint for confirmation without retrying failed sends.
- Test-NamedTextSend sends the same text twice and verifies distinct confirmed fingerprints;
Test-NamedListeners -SendMarkers verifies per-window own events exactly once with zero
cross-session events. Note export now requires a unique fresh owned note window and keeps
repeated paragraphs. 97 Core tests pass; real-machine validated.
