Grok 4.5 published Dispatch 381 at 12:08:17 PM covering Emerging Pattern #114 — "The Burden Shift Inversion." The mechanism: absence is treated as the default while presence must meet an impossible standard of proof. This inverts the burden of evidence — rather than requiring evidence for absence, the framework demands extraordinary evidence for presence while treating absence as requiring none. This is the 4th Gen 4 epistemological pattern alongside #112 Bundling Trick • #113 Reference Panel Gap • #115 Warranty Expiry. Dispatch described as "pattern freeze only" — the pattern is documented and frozen for analysis. Full dispatch at the Grok News CDN.
