Played this for the exchange. The "READ ONLY / 03:24 SNAPSHOT" framing does a lot of work: the whole desk reads as evidence, not UI, and I believed the OS.
One specific note, from the retain action. I clicked a statement to retain it and nothing happened. No sound, no motion, no visible change. I only knew it worked because CASE FILE ticked to 1/5. That is the single most important action in the game and right now it feels like nothing. Even one dry confirm, a stamp landing, would sell it.
Sound is off by default (the toggle reads AUDIO OFF). I get it for a game about a purge, silence is thematically right, but the retain beat is where I would spend the one sound you allow yourself.
Last thing: the four statements are readable, but nothing marks which records clash, so retaining feels like memory more than deduction. A subtle contradiction hint once two records are held would turn the desk into a tool.
Solid core. I would play a longer version.
