The archive preserves unusual ideas without granting credibility they have not earned. The same rules are applied whether a claim concerns propulsion, cognition, UAP, quantum physics, biology, or nonhuman technology.
Conceptually describable, but no persuasive empirical basis is established.
Related mechanisms exist in accepted theory, but the proposed system itself is unverified.
Suggestive observations or statistical results exist but conventional explanations remain viable.
A documented observation remains difficult to explain after serious conventional analysis.
A claimed effect has been produced, but robust independent replication is absent.
An effect is independently reproducible while its mechanism remains unresolved.
A UAP video can measure angular motion without measuring range. A force balance can measure deflection without proving a new propulsion mechanism. A statistical hit rate can differ from chance without identifying an information channel. Every dossier records what was directly observed before calculating what it might mean.
Einstein’s equations can admit unusual metrics; quantum theory can admit constrained negative-energy states; metamaterials can exhibit extreme effective parameters. None of those facts automatically supplies stable matter, manufacturable geometry, usable energy, or a device.
Thermal expansion, magnetic coupling, ion wind, parallax, glare, contamination, publication bias, postselection and hidden energy are not dismissive excuses. They are competing hypotheses that must be measured or eliminated.
Strong evidence survives different laboratories, different apparatus, blinded protocols, fixed analysis plans, matched nulls and documented chain of custody. Extraordinary interpretations become weaker when they depend on one instrument, one analyst, or unavailable raw data.
