State Estimation Will Display Uncertainty
PCS S(t) requires not only a central estimate but also confidence intervals, data gaps, and source-quality information.

The PCS common state S(t) cannot be a single apparently precise number. Sources contain measurement error, latency, coverage differences, and missing observations, so state estimation must display uncertainty and data quality.
The interface will distinguish observations, normalized indicators, model estimates, and visual previews so users do not mistake different evidence levels for equivalent results.
