Pre-Commit States at Cosmological Scales: The Metastable Electroweak Vacuum and the Holographic Ledger Framework

The measurement of the Higgs boson mass at approximately 125. 09 GeV places the electroweak vacuum in the metastable regime of the Standard Model. The vacuum is locally stable but not the global energy minimum, with a non-zero probability of quantum tunneling to a lower-energy state on timescales exceeding 10⁶00 years. This paper argues that the metastable electroweak vacuum constitutes a structural realization of a Pre-Commit State as defined within the Holographic Ledger (HL) framework. Four core features are identified that map directly onto the HL formalism: local persistence without global stability, irreversible transition upon crossing a threshold, epistemic boundary for internal observers, and thermodynamic consequence of the transition. A fifth distinguishing criterion — information-thermodynamic measurability — separates HL Pre-Commit States from generic threshold-driven phase transitions. A second, independent cosmological example — core collapse in self-interacting dark matter (SIDM) halos — is shown to exhibit the same structural pattern. The implications of the quantum observer problem are examined and reframed as a question of measurement conditions rather than metaphysics. The analysis reinforces the HL programme's core methodological commitment: structural isomorphism across scales, without claiming physical identity.
