This record archives Version 1. 3 of the TCVR-Q manuscript. TCVR-Q is formulated as a conservative effective quantum framework in which standard quantum mechanics is recovered in the zero-coupling limit, while a small Planck-suppressed residual-response term is added to quantum phase evolution. Version 1. 3 extends the previous formulation by adding an experimental sensitivity forecast and explicit null-test bounds on the dimensionless coupling parameter etaQ. The framework introduces a unified residual-response variable, XTCVR, whose projections appear as SCQR in coarse-grained astrophysical coronae and as SQ in controlled laboratory quantum systems. The modified Schrödinger equation contains a channel-dependent energy scale E_*, equivalently Omega₀ = E_*/hbar, and predicts a small path-dependent phase shift in interferometric systems. The new version derives representative bounds on etaQ for linear and quadratic Planck suppression, compares different environmental length scales, and includes a sensitivity plot showing how null phase-shift measurements can constrain the model. The framework does not claim a direct detection of TCVR, does not replace standard quantum mechanics, and does not assume observer-induced wavefunction collapse. It is presented as a phenomenological, Planck-suppressed residual-response parameterization compatible with standard quantum mechanics in the appropriate limit.
