[RECOVERED_LOG.TXT]

"If you're reading this, you've noclipped out of reality. I don't know how deep this place goes, but it’s just miles of the same yellow wallpaper.
Listen to me carefully: The things in here react to noise and aggression. If you panic, if you run, or if you try to fight… the whole place seems to get angry. It starts to b r e a k.
Keep your head down. Stay quiet. If you treat this place with respect, maybe it will let you go home."

    // The system has stopped rendering false positives.
    // NOTE: All remaining anomalies are now confirmed valid data.
  + ACCELERATED: ENTROPY_TIMER.
    // Runtime integrity duration has been reduced.
