Planetary Signal Architecture IV: Signal Recovery
Signal recovery is the final step in planetary reconstruction: identifying, testing, and interpreting surviving information without forcing the model.
The Entrance
Antarctica remains the first recovery domain for evaluating preserved signal.
The Exit
The Arctic Circle remains the second recovery domain for opposing-response comparison.
The Middle Mountain
The middle mountain remains the central recovery domain linking entrance and exit observations.
Observational Constraints
Signal recovery requires geophysical datasets, structural correlation, mantle tomography, gravity analysis, geological continuity, and independent verification.
Reconstruction Question
How can preserved planetary signal be recovered without confusing signal, noise, and later overprint?
Transition
The next sequence examines signal-to-noise filtering, competing explanations, null models, and falsifiable recovery tests.
