Measurement & Inferred State

Primes about inferring a system's true state from observation: measurement, noise, and uncertainty, observability and observer effect, conjugate-variable and disturbance trade-offs, construct validity and controlled comparison, plus the failures of proxy-target divergence, reference decay, and extrapolation beyond the sampled regime.

18 primes in this family — primes that sit near one another in abstraction space (k-means over structural-signature embeddings). Each is shown with its structural–framed character and how distinctive (sparsely-neighbored) it is.
