SECTOR PAPER XIX — Local-Scale Emergent Proper Time, Forced Worldline Geometry, and the δI‑Driven Collapse of Classical Time Dilation

Sector XIX presents the emergence of local proper time from the δI‑substrate, demonstrating that classical relativistic time dilation is not fundamental but an induced geometric shadow of correlation‑flow. The sector shows that worldline geometry, local clock‑rate variation, and horizon‑proximal time collapse arise directly from δI‑gradient structure without requiring metric‑based time dilation. Proper time becomes an emergent, correlation‑driven quantity rather than a primitive spacetime parameter. This paper establishes the substrate‑level origin of local temporal behaviour and forms the fourth component of the horizon‑collapse chain.
