Individual Five-Dimensional Witnesses in SInC

The Witness sector is taken to comprise individual five-dimensional entities; wavefunctions and densities describe those entities without constituting their ontology. This supplement selects one explicit massive-worldline completion and includes the distinct ECO gravitational carrier in the same effective action. It derives entity motion, reciprocal substrate and carrier reaction, source work, linear transfer, stability conditions and a conditional joint quantum description. Overdamped motion is a reservoir-dependent limit rather than a mass-free replacement for those requirements. Transverse binding, brane-boundary-sensitive tunnelling, lateral confinement, capture and causal readout are treated separately. The carrier audit is retained independently of the entity representation. A 100-Hz binary of two 1019-g ECOs gives strain 6.19 × 10−34 at 1 AU and a favorable whole-brain tidal-energy envelope 2.00 × 10−10kBT at 310 K. Specified thermal and AWGN channels give about 2.9×10−18 and 5.8×10−18 bits/s, respectively, without establishing a universal neural capacity bound. Collective spectra, phase modulation and zero-lag coherence require source power, physical transfer and noise; neither a carrier oscillator nor an entity wavefunction supplies them automatically. The worked localized entity modes are fast and give a leading static potential shift in the neural band. The construction is internally coherent within its stated domain, but cannot reconcile the unchanged strain, bandwidth, dormancy and spectral assertions of the original corpus. It specifies the required rewrites and retains the failed benchmarks. Mechanical responsiveness and quantum correlation do not identify subjectivity or establish an operational conscious communication channel.
