This Zenodo record collects the June 2026 working series of the Coherent-Affine Substrate (CAS) programme. The series develops a conditional, gate-led research framework in which metric spacetime, Lorentzian readout, matter sectors, gauge normal forms, cosmological branches, quantum-field-theoretic readout, and observable interfaces are not assumed as primitive, but are introduced through explicit mathematical layers, reductions, and falsification gates. The collection includes the seven core CAS papers, together with companion technical documents: a Lagrangian atlas, an observable-interface calculation pack, a QFT lift, a forward observable ledger, and a Gate Closure Master Ledger. The documents are intended as a structured research corpus rather than a finalized theory claim. They separate derived statements from conditional constructions, distinguish local closure from full global proof, and record open obligations such as full-L0 reconstruction, invariant-catalog completeness, quantum consistency gates, observable push-forward, and anti-fitting requirements. This release is useful for external review, reproducibility checks, dependency auditing, and citation of the CAS programme as a coherent preprint series. It should be read as a staged theoretical framework with explicit claim boundaries, not as a completed phenomenological model or experimentally validated theory.
