The Page Curve as Gravity’s Area-Bound Consistency Check

Fibers on X

False identity

Art.5 is not Th.5 Stabilizer. It is Th.4 Page Curve — open the living join.

What the data actually shows: Reproducing the Page curve has become a minimum consistency check, not a distinguishing prediction. Many proposals reproduce it without offering new, falsifiable predictions.
Why this is necessary: Gravity’s area bound is a fundamental information-capacity limit. The Page curve is simply the time-dependent profile that emerges when a system respects both unitarity and this area bound.
What current approaches miss: The field became fixated on solving the information paradox. Once the Page curve emerged, many treated matching it as the finish line.
If this is right: Raises the quality bar for quantum gravity research. Future proposals will be judged primarily by their novel, testable predictions beyond the Page curve.

One domain counter per cluster, not a repeating method quartet. The mirror reads these as enough to refuse necessity.
