Precision Cascade Cosmology — Audit-Certified Master Reproducibility Archive (v1.0.0)

Abstract This record releases the final, audit-certified master reproducibility archive for the Precision Cascade Cosmology programme. The archive binds five interdependent research packages into a single cryptographically sealed, self-auditing scientific system through deterministic execution, golden-output validation, cross-pack auditing, and DOI-based canonical referencing (rather than physical embedding). The Precision Cascade framework is founded on a prior resolution of the Hubble tension through systematic correlation synthesis, and extends this methodology to the validation of cosmic flatness, the detection of self-interacting dark matter (SIDM), the large-scale empirical validation of General Relativity, and the formulation of the Precision Cascade law governing correlated physical consistency across independent domains. This release provides a fully deterministic, machine-verifiable, and forensically auditable scientific object: including canonical datasets, minimal and full execution pipelines, schema and unit validators, cryptographic integrity layers, provenance manifests, independent replication tooling, and cross-package certification. No scientific reinterpretation, re-derivation, or modification of published results is performed; all computations mechanically reproduce the original equations, datasets, and reported values. Designed for adversarial audit, long-term archival preservation, and independent laboratory verification, this master archive establishes a new standard for transparent, reproducible, and integrity-sealed scientific publication. Description Overview This Zenodo record contains the final, audited Precision Cascade Master Archive: a unified, cryptographically bound reproducibility system for the Precision Cascade Cosmology research programme. The archive does not alter, reinterpret, or re-derive any scientific results. It is a mechanical, audit-grade reproducibility infrastructure that ensures every published metric, figure, and dataset can be independently verified, reproduced deterministically, and traced back to its original source through cryptographic hashes, structured provenance, and DOI-linked canonical artifacts. Scientific Scope The Precision Cascade programme demonstrates that multiple longstanding and independent physical results are mutually consistent when cross-correlations, covariance structures, and domain-to-domain dependencies are treated explicitly and systematically. The framework is founded on a prior resolution of the Hubble tension through correlation synthesis and extends that methodology to: empirical confirmation of cosmic flatness, detection and parameterization of self-interacting dark matter (SIDM), large-scale validation of General Relativity, and formulation of the Precision Cascade law, describing how independent physical constraints combine into a single, coherent, high-significance structure. Together, these results form a tightly coupled, cross-validated scientific framework rather than isolated claims. Archival Structure and Scope This master archive binds five interdependent research packages into a single system of record through cryptographic integrity, audit artifacts, and DOI-based canonical referencing. Important archival clarification:The foundational Paper I reproducibility archive (Hubble-tension resolution) is not physically embedded within this master package. It is preserved as an independent, canonical archive and is referenced here by cryptographic hash and DOI (https://doi.org/10.5281/zenodo.17509082). This avoids duplication, preserves archival sovereignty, and ensures that each component remains individually citable, auditable, and immutable. The present record therefore functions as a master audit and integration layer, not a nested data bundle. Reproducibility Architecture This release provides a complete, deterministic, and self-verifying scientific object, including: Canonical datasets and paper-faithful source files Minimal and full deterministic execution pipelines Golden-output validation tables with explicit tolerances Schema and unit validators Cryptographic checksums and root-hash sealing Provenance manifests and run-environment records Independent replication kits for external reviewers Cross-package audit tooling and certification artifacts All outputs are reproducible offline, with bitwise determinism on pinned environments and tolerance-bounded validation across platforms. Integrity and Audit Guarantees This archive is designed for adversarial verification. It enforces: cryptographic fixity of every file, deterministic execution with no hidden state, mechanical reproduction of published equations only, traceable lineage from raw data to final metrics, and explicit prevention of scientific reinterpretation or modification. Any alteration to any artifact is immediately detectable through checksum validation and cross-pack audit tooling. Preservation and Citation This release is intended as a long-term archival scientific object. All formats are open and non-proprietary, all dependencies are pinned, and the archive is suitable for institutional repositories, national archives, and independent laboratory certification. Each component paper retains its own DOI. This master archive provides the integrative, cryptographically sealed system of record that binds them into a coherent, verifiable scientific framework. Intended Use This archive is suitable for: journal and institutional reproducibility audits, independent laboratory replication, research-integrity verification, long-term digital preservation, and formal citation as a unified scientific object. No scientific content is modified. All results remain exactly as published.
