Pending confirmation / 待确认: the supplied material does not support a complete guide.
The supplied novice guide explains Evac as shorthand for Evacuation and calls it the True Ending. The All Pages directory also lists Evacuation in its Endings section. Entry conditions, trigger sequence, extraction objectives, and rewards remain pending confirmation / 待确认.
What the two references contribute
One reference explains a communication abbreviation, while the other establishes a directory category. Neither contains the complete Evacuation walkthrough. No Lab route, key item, or boss requirement is invented by combining the two short references.
