This repository is a verification-first release of SFT: a theory/framework plus a set of runners designed for external audit. Update — Firedrake/UFL verification of a structural scalar-field model: spin-½ FR signatures, hydrogenic radial gates, and solar-system perihelion tests Update date: 2026-06-16 This repository now includes SFT_FIREDRAKE_CORE_REPRO_v0_1_8, an exploratory Firedrake/UFL real-solver bridge package. This package adds external PDE/FEM bridge outputs for selected SFT-facing audit targets, including: spin-½ FR bend robustness signatures, hydrogenic radial Coulomb H/T 2s/2p gates, Venus and Mercury 1PN perihelion geometry gates, alpha-localization capacity scans, double-slit Firedrake phase/visibility diagnostics, and an intentionally incomplete Alpha-Out bridge report. These Firedrake/UFL outputs are stronger than synthetic CI checks because they are produced in an external real-solver environment and exported as auditable JSON/CSV artifacts with SHA-256 manifests and PASS/FAIL gates. They are not presented as global physical validation of SFT, nor as derivations of the Standard Model or General Relativity. They should be read as an exploratory P-bridge: real-solver bridge outputs that exercise the verification-first contract, while still requiring independent third-party REAL runs at multiple resolutions for physical confirmation. Evidence labels used in this repository: CI (C): CPU-only validation of tooling, schemas, manifests, regression checks, and PASS/FAIL logic. REAL-ready (P-input): verifier and artifact contract are ready to ingest third-party real-solver outputs. Exploratory P-bridge: real-solver bridge outputs produced in an external solver environment, with hashes and machine-checkable reports, but not yet independently replicated. REAL-verified (P): reserved for independent third-party real-solver runs with artifacts, hashes, locked gates, and at least two resolutions. https://github.com/Xaquer69/sft-theory-and-runners
