GCFT Part IV: The Falsification Era — CDN-150 through CDN-159

GCFT Part IV collects CDN-150 through CDN-159, the pre-registration campaign and structural analyses that define the current falsification state of General Coherence Field Theory. The ten papers were written in anticipation of Gaia Data Release 4, which will simultaneously adjudicate four independent tests of the CDN-142 density-screened coupling architecture (kappa=0.15, rho_crit=1e4 M_sun/kpc^3). CDN-150 formally pre-registers the kill and confirm criteria for Leo I escape velocity, Crater II binding, and the 22-satellite population survey — locked before DR4 data become public. CDN-151 establishes Crater II as the sole rescue candidate in the CDN-149 boundary survey: unbound in LCDM, marginally bound in GCFT via +16.9 km/s of density-screened coupling at r=116 kpc. CDN-152 corrects the Local Group timing argument mass for GCFT coupling during the wide-separation epoch, revising M_LG from 3.17 to 2.13 × 10^12 M_sun. CDN-153 resolves the charm-node paradox by identifying compactness C=M/r^3 as the field selector: internal density, not orbital location, determines screening. CDN-154 and CDN-155 synthesize the full prediction landscape and enumerate all Gaia DR4 outcome scenarios. CDN-156 derives a hard lower bound M_MW > 0.97 × 10^12 M_sun from the Crater II rescue signature under the CDN-152 mass revision. CDN-157 predicts a +15% HI column enhancement in the Magellanic Stream trailing arm — testable now with HI4PI data, no DR4 required. CDN-158 formalizes CDN-143 Prediction 2 as a steeper-than-LCDM AGN fraction gradient across environments. CDN-159 formalizes CDN-143 Prediction 3 as a top-heavier IMF slope in GCFT active zones relative to screened environments. The CDN-142 parameter set is unchanged throughout and enters Gaia DR4 with fully locked, pre-registered falsification criteria.
