- **PRD acceptance harness: typing rows no longer give up on a stalled renderer, and the Word round trip clicks inside the canvas (#4805).** A status read that took longer than 200 ms stopped `typeLines()` for good, so the late-write and restart rows never had an accepted line. An unanswered read now only leaves that line unproven. The rows wait up to 30 s for the first accepted line, and the failure message carries the typing progress. The comment click is anchored to the canvas's right edge instead of a fixed x that fell outside the current layout.
