Project P.I.T.T. Secrets
Source-labelled Project P.I.T.T. secret leads, including height and darker-area guidance, without invented solutions.
The secret-route evidence chain for 1.0.8 is Fuses → 200kg → Percentage Pipe → IGTAP → Mining → UV → Keycard → Elevator → Secret Ending. This is an investigation sequence, not a verified complete walkthrough: official fixes, older community consensus and unresolved conflicts are labelled separately.

Fuses — OFFICIAL CURRENT
The official 1.0.6 recovery rule returns an unplaced fuse to its spawn when saving; placed fuses are the exception. That historical fix remains the documented baseline, not a verified map of all locations. An older community guide reports three fuses, but no full 1.0.8 route was reproduced here.

200kg — DEFERRED
DEFERRED — EVIDENCE INSUFFICIENT. Older player evidence describes a weight platform, but accepted current-build item weights remain zero. No verified loadout, mass table or functioning calculator is claimed. Steam hides the public requirement text for HEAVY?.

Percentage Pipe — CONFLICTED
Older independent player sources point to Anomaly inputs, but reports conflict over whether earlier products also add progress. For the current build, accepted inputs, increment per input, total count, the 100% result and Anomaly-quality effects are not verified. The 1.0.8 quality changes make a new isolated test necessary. Do not assume 10 Anomalies × 10%. Standalone guide: DEFERRED — EVIDENCE INSUFFICIENT.

IGTAP — CONFLICTED
The older strategy guide uses conflicting per-second and per-minute units for an IGTAP power condition. No current-build reproduction resolves the threshold, required setup or next transition. DEFERRED — EVIDENCE INSUFFICIENT; neither number is promoted into instructions.

Mining — OFFICIAL CURRENT
Update 1.0.8 explicitly changes each mining upgrade from five ores to three. This is a verified patch fact, not proof of the total upgrade count, every ore location, or the next secret-route unlock. Older five-ore walkthrough instructions are stale for this change.
UV — MULTI-SOURCE COMMUNITY CONSENSUS
An older first-hand guide and a separate missing-digit discussion corroborate a UV clue on the manual Duck machine and searching machine/pillar clues. This classification concerns that limited older-build observation, not a replayed full route in 1.0.8. Exact current unlock conditions and a complete digit-discovery sequence remain deferred.

Keycard — CONFLICTED
The older first-hand guide describes a pickaxe plus three earlier products, while other public walkthrough claims differ. None establishes a reproducible current-build Keycard recipe after the Cauldron update. Do not consume a unique item based on that conflict. DEFERRED — EVIDENCE INSUFFICIENT.

Elevator — DEFERRED
Update 1.0.8 fixes keypad interaction but does not publish a universal code. The reviewed first-hand guide describes save-specific digits. Do not use 2640 as a universal code or copy another save's sequence as a guaranteed solution. Current code order and complete elevator transition: DEFERRED — EVIDENCE INSUFFICIENT.

Secret Ending — DEFERRED
DEFERRED — EVIDENCE INSUFFICIENT. The full current-build sequence and final trigger are not reliably reproduced. END? and END! have hidden public descriptions, so their punctuation is not proof of a main/secret mapping. The preserved evidence-status page remains noindex.

Testing a secret theory safely
Back up the current save before testing a theory. Record build, before/after state and the exact input so another player could reproduce the result. No step here is labelled IN-GAME VERIFIED without such current-build evidence.
Do not use 2640 as a universal code. The reviewed first-hand guide describes save-specific digits; an independent player discussion corroborates looking for a UV clue on the manual Duck machine. Those are older community observations, not a published global code or a completed 1.0.8 route.
