The current corpus converts broad extraordinary claims into narrower scientific questions: what is established, what is inferred, what has failed replication, and what evidence would change the file.
The supplied propulsion report treats the central problem as a measurement and conservation-law question: a genuine closed-system thrust signal must survive increasingly hostile controls, not merely appear on a sensitive balance.
The temporal-engineering report draws a hard line between verified differences in proper time and hypothetical routes to the past.
Dimensional engineering asks whether spacetime geometry could become an engineered medium. The report repeatedly distinguishes a metric that can be written down from a geometry that can exist, remain stable and be manufactured.
The vacuum-energy report separates the reality of quantum-vacuum phenomena from the much stronger claim that the vacuum can be used as a limitless net-energy source.
Unlike many HSARPA topics, the core of this dossier is already real engineering. The speculative boundary appears when demonstrated narrowband or microscale effects are projected into universal invisibility, arbitrary shape changing or science-fiction matter.
The gravity-control report uses precision gravimetry and repeated null results to set a high bar: artificial gravity by acceleration is real, but localized shielding or strong field generation has not been demonstrated.
The cognition report treats paranormal claims as an experimental-design problem and uses known perception, implicit learning, predictive processing and modern brain interfaces as comparison baselines.
The FTL report treats information speed as the key quantity. Nonlocal correlations, phase velocities and tunneling times can look superluminal without giving a sender controllable bits outside the light cone.
The technosignature report reframes SETI as anomaly detection: search broadly for engineered signatures, then make the artificiality claim only after natural and instrumental alternatives have been aggressively tested.
The alternative-life report uses terrestrial synthetic biology to show that DNA and RNA chemistry are not the only conceivable information architectures while keeping naturally occurring shadow biospheres in the unverified category.
The simulation report treats the simulation hypothesis primarily as a philosophical and information-theoretic framework. Proposed physical tests can constrain models of discreteness or Lorentz violation without uniquely proving an external simulator.
The UAP report is built around an evidence hierarchy: direct measurement first, inference second, interpretation last. Missing range or geometry can turn apparent extraordinary motion into an underdetermined observation.
