DEVLOG #21

The 65-second empty-room calibration failed before it could collect a usable
baseline. The UI showed Samples 0 when I returned, so no calibration ID or
context hash was created.

The failure exposed a design problem in the run itself. A recoverable
outside-room radar target could stop the entire measurement. I’m changing the
workflow so the run always reaches its configured end and evaluates the
evidence afterwards. The final report will mark it valid or invalid with
concrete reasons instead of hiding the failure behind an early stop.

This behavior change is planned, but not yet implemented or validated. No
successful calibration, restored baseline, 10/10 acceptance, position index,
guided room walk, or blind-test result is claimed.

Next: implement and test the non-interrupting run plus the post-run validity
report
