RuView: Presence Detection Gets Honest
Two calibration fixes in the presence detection pipeline addressed cases where the system quietly reported wrong occupancy data instead of failing loudly, while a firmware runbook fix closed a gap where the wrong build could ship without any error.

This is RuView for September 14th, 2026.
The signal today: three separate fixes, all sharing the same failure mode — systems that looked fine but were quietly wrong.
Start with presence detection. PR 1917 fixed a case where a person sitting motionless on the floor registered as zero occupants, because the empty-room boundary was derived from a calibration threshold that didn't account for that scenario. The person was there. The detector saw them. The publication gate just never…
Second theme: silent misconfiguration. PR 1925 caught a firmware runbook problem where the documented build command for the C6 board concatenated three config files in an order that let the last one silently override flash size — producing a 4MB image on 16MB hardware. No build error, no warning. Just the wrong…
One more item: PR 1920, an automated dependency change touching package lock files, drew a single review comment. No indication yet of broader impact.
What to remember: when a system fails by staying quiet instead of throwing an error, it's the harder bug to catch and the more important one to fix. Today's fixes all close that gap — in occupancy detection and in build documentation.
