Gravitational Manipulation Theory v3.0: An Auditable Mechanism-Verification Architecture for Sealed and Reproducible Physics Workflows

GMT v3.0 presents an auditable mechanism-verification architecture for sealed and reproducible physics workflows. It defines a controlled sequence for package admission, model freeze, trust-root authorization, deterministic execution, checkpoint protection, adjudication, provenance chaining, and external anchoring. The deposited materials include the GMT v3.0 preprint, the Rev.F Publication Bundle, and the associated design documents. The architecture contains unit-tested primitives for canonical serialization, SHA-256 hashing, Ed25519 signatures, seal verification, checkpoint validation, chain continuity, and fail-closed authorization. A built-in adversarial harness completed 90 of 90 specified checks. This result applies only to the included mechanism-verification harness and does not constitute full-pipeline physics validation, production qualification, security certification, or a formal independent third-party audit. The materials underwent an AI-assisted preliminary adversarial review and, separately, a probe-based re-evaluation. These reviews identified and helped correct implementation and documentation issues, but they must not be interpreted as independent certification. At the time of this release, TRUST_ROOT_SHA256 remains set to None, so official execution is designed to fail closed. The physics kernel has not yet been integrated into the official execution path. Consequently, this release establishes an auditable verification architecture and publication baseline, not a completed experimental result or validated claim of gravitational manipulation. The release continues from the GMT v2.9 Rev.P execution record and references the associated GMT v2.9 preprint. Reserved Zenodo DOI: 10.5281/zenodo.22144911.
