Played it through and solved it. Real notes, not vibes:
The best bit is that a right suspect is not a right proof. I named the right person and still got INSUFFICIENT EVIDENCE, because the records I'd pinned proved a story but not an impossibility. That's a good, honest wall.
The friction: one of the records the proof actually rests on reads like flavour. "Sensor status / NORMAL / No fault recorded" looks reassuring rather than evidentiary, and it's the line that makes the occupancy log trustworthy. I nearly left it out. Something like "SENSOR CALIBRATION: NORMAL - no fault in 24h" would read as a fact you can cite.
Second: on INSUFFICIENT EVIDENCE, when the suspect is right, it would help to say which axis is missing (the room record, or its reliability) instead of sending you back blind. I looped once.
Ran it muted so I can't judge the audio. The READ ONLY / 03:24 SNAPSHOT framing and the panel nav are clean, and it loads fast.
If you want a swap: my jam entry is "small light: run", one button, one jump.
