Project P.I.T.T. UV Lamp Not Working: Diagnostic Checklist
UV Lamp Not Working: Diagnostic Checklist: The UV tool is collected but the expected clue is absent? Look at the identified machine surface rather than nearby floor lettering.
The UV tool is collected but the expected clue is absent? Look at the identified machine surface rather than nearby floor lettering. The manual Duck workbench lead is community evidence, and a copied number is not a substitute for the digits in your save. These are diagnostics, not a guaranteed fix.
Separate the symptom from the assumed cause
The UV tool is collected but the expected clue is absent. Check activation and your own binding before investigating a clue. The 1.0.5 light change documents default T; older players separately describe UV clues on machinery.

Patch and evidence boundary
Update 1.0.5 changed collection behavior and states that default T activation is still required. The patch note does not document every final-release interaction. If the failure persists, retain a before-and-after capture rather than asserting a missing level, an undocumented key or a numerical setting.
