The CERN antihydrogen programme pursues three stated scientific goals: testing CPT symmetry between matter and antimatter to unprecedented precision, measuring whether antimatter falls under gravity identically to matter, and finding the physical origin of the matter-antimatter asymmetry of the observable universe. This paper states what the Big Flare-Up Theory (BFUT) framework predicts for each of these three goals, and explains why the third goal will not be achieved through antihydrogen spectroscopy alone. The BFUT account of antimatter derives from BFUT Paper 16 (P16), which establishes that approximately 80-85% of quark-class excitation parameter space produces the stable 3+1 topology that becomes matter, while the remaining 15-20% produces unstable excitations that generate their own equal and opposite substrate rebound at the moment of formation. That rebound is the antiparticle. The matter-antimatter asymmetry of the observable universe is therefore not a mystery requiring an unexplained asymmetric process. It is the direct output of the stability filter operating at quark-class formation level. Four specific falsifiable predictions are stated for the CERN programme. The antimatter account presented here is not an isolated speculative proposal. It emerges from the broader BFUT substrate programme, which has already derived the four fundamental forces from Spaticle substrate mechanics; reproduced multiple Standard Model parameters including the fine structure constant, strong coupling constant, W boson mass, Z boson mass, and electroweak mixing angle from the same free-energy functional coefficients; established a substrate-level account of quantum mechanics and reinterpreted Higgs-sector phenomenology as emerging from the Spaticle substrate rather than from a separate universal mass-giving field; derived the Higgs boson mass to within 0.21% of the measured value while additionally predicting five further resonance levels emerging from the same substrate hierarchy structure; and validated substrate-based gravitational dynamics against 175 galaxy rotation curves (chi-squared 1.31 versus MOND chi-squared 1.47) and independently confirmed through KiDS-1000 weak gravitational lensing and GW170817 post-merger carrier relaxation analysis (tau approximately 6.8 ms within the predicted 1-15 ms window), all without particulate dark-matter halos. The BFUT framework argues that dark matter has already been observed for decades and identifies the Spaticle field as its physical nature: it satisfies every operational property historically attributed to dark matter and is validated across three independent physical regimes from one substrate density with no free parameters. The BFUT framework therefore covers and extends the empirical scope of the Standard Model across particle physics, quantum mechanics, gravitation, and cosmology from a single substrate-level derivation chain. The present paper extends that same framework specifically to antimatter, annihilation, and the CERN antihydrogen programme.
