Dirac-Like Propagation of an Electron-Like Response Packet in ECSM

This paper presents the V6b dynamical propagation test for an electron-like response packet in the Emergent Condensate Superfluid Medium (ECSM) framework. Building on prior occupancy, SU (2), and Clifford/Dirac closure tests, the paper constructs an exact spectral positive-branch packet and evolves it under a Dirac-like Hamiltonian. The V6b test passes all fourteen final criteria: the packet remains on the qₑff ≃ -1 scaffold, preserves inherited Clifford and alpha/beta closure, propagates unitarily, suppresses initial negative-branch leakage to numerical precision, avoids dynamical branch amplification, conserves total branch weight, preserves response-deformed conservation, and maintains positive-negative energy symmetry and orthogonality. The result does not claim to derive the physical electron or calibrate the electron mass. It establishes a narrower internal consistency result: a minimal ECSM electron-like response packet can host dynamically stable Dirac-like spectral propagation.
