Why this page exists
Keyword research and competitor sitemaps show key-location demand. The gap is real, but the available competitor claims are not strong enough to publish exact Clean The Library key routes as fact.
This page keeps the search intent covered while making the evidence boundary visible. It should become a full guide only after direct gameplay checks, creator notes, or a current video with clear map context.
What would count as publishable evidence
A publishable key route needs the map version, floor, nearby section code, screenshots or clear video frames, whether the key appears every run, and the checked date. A copied list from another fan site is not enough.
If the key is tied to Grand Library, Pro Mode, events, badges, or Ascend, the guide should say that explicitly and avoid mixing classic-map advice with endgame-only mechanics.
What to do today
If you are stuck in a live run, finish the normal shelf audit first: check nearby clutter, carried stacks, wrong-category rows, and volume order. Do not abandon a clear because an unverified key-route page says to search somewhere else.
Use the source checklist and updates page to see whether this topic has moved from watch status to verified route content.
