What the list counts

Every row is one pin the game files place at a fixed spot, so the list is exact for what it covers. It does not contain fragments that the game rolls at random in each new game, and the files hold no completion percentage of the game's own, so "100%" here means every fixed find on this page. Where to start: the walkthrough lists the key blueprints from the surface down.

Position and depth are the game's world metres; the area is the label of the game's biome map at the pin and ignores depth. The text of the PDA logs is the studio's and is not copied.
