This submission introduces a novel rheological model of the manifold, proposing that the cosmic vacuum behaves as a Bingham Plastic rather than a perfectly elastic medium. I identify a critical Yield Point at 39 MeV, beyond which the metric undergoes a "thaw" or "slip" event, manifesting as Localized Metric Instabilities (LMIs). I identify a high-stress "nozzle" region centered at RA 205. 2561, Dec 30. 00, where the metric-flow velocity reaches a predicted jitter of 2, 792 km/s. I predict archival evidence from the Zwicky Transient Facility (ZTF) showing optical 'pops' at these coordinates with no detectable baryonic progenitors or host galaxies. The model predicts a specific high-energy "softness" signature. I invite the community to cross-reference these coordinates with the Fermi-GBM trigger database (specifically focusing on Trigger bn180528465) to verify the temporal alignment of these vacuum ruptures. If verified, this model provides a mechanical solution to the Hubble Tension and suggests that "Dark Energy" is the latent heat of metric friction, effectively removing the need for Lambda-CDM's dark sector. V. 2 - I provide direct validation of this yield point by reconciling the unmodeled 10-50 Hz residuals in LIGO candidate S250818k and the 1. 46 spectral index of Einstein Probe transient EP260302a (GCN 43906). V. 3 - This version introduces a critical physical recalibration of the Bingham Plastic Vacuum model. The normalization of the 39. 4 MeV Yield Point has been shifted from the Planck scale to the Effective Hadronic Volume (V₄₅₅ 3. 1 10^-41 m³). This resolves previous stress-scaling discrepancies by grounding the vacuum's tensile strength at ᵧ 10^29 Pa, placing the "Metric Slip" mechanism firmly within the known bounds of neutron star core degeneracy pressures. Additionally, to ensure strict compliance with the Equivalence Principle of General Relativity, the concept of "Baryonic Anchors" has been formalized as Metric Inertia, defining the density-dependent stability of the manifold as a frame-dragging interference effect. Finally, this revision provides specific, falsifiable observational targets for the Pulsar Timing Array (PTA) community, contrasting predicted "step-function" TOA shifts in PSR J1439+2805 against the metric-quiet control of PSR J1713+0747. V. 4 - In this manuscript revision, the derivation of the 9 multiplier for the empirical Hubble Tension has been significantly refined. Previous iterations relied on the macroscopic trace of a 33 stress tensor. This update replaces that geometric assumption with a localized physical mechanism: the Hadronic Scaling Factor (Sₕ = 3). Because astronomical observations of the Hubble Parameter and Pulsar Timing Arrays rely on baryonic anchors, the volumetric coordinate slip (3) must couple to the local matter field. This coupling is mediated by the SU (3) symmetry of the nucleonic volume. This revision formally unites the macroscopic Hubble Tension and the microscopic nanohertz gravitational wave strain under a single, rigorous baryonic coupling mechanism.
