CEDA is a diagnostic framework for early-universe cosmology. It is not a cosmological model, not a mechanism, and not an alternative to inflation or ΛCDM.

Its purpose is narrow and deliberate:
to audit early-universe proposals for explanatory provenance under strict, conservation-honest accounting.

CEDA asks a simple but unforgiving question:

Where does the claimed physical behavior actually come from—dynamics, or description?

The framework provides:

• A standardized Model Card for making assumptions explicit
• A structured stress-test suite that separates genuine dynamics from descriptive reweighting
• Clear diagnostic classifications (mechanism, reinterpretation, descriptive instability, underspecification)
• A formal failure catalogue naming recurring conceptual pathologies without rhetoric

CEDA emerged from internal null results demonstrating that horizon-mediated accessibility reconfiguration, when treated honestly as bookkeeping, does not generically produce inflation-like behavior. Rather than rescuing the idea, the framework formalizes the diagnostic lesson.

The result is an audit tool designed to clarify—not compete with—successful cosmological mechanisms.

Status: For external review

• Conservation-honest bookkeeping in effective descriptions
• Separation of genuine dynamics from descriptive artifacts
• Diagnosing inflation-mimicking constructions without appealing to observational fit
• Clarifying why successful inflationary models require additional structure
• Building reusable diagnostic language for referees, reviewers, and model builders

• U.S. Army Veteran
• Experience building and maintaining complex, constraint-heavy systems
• Nonprofit operations and compliance leadership (501(c)(3) treasurer)
• Longstanding interest in physics, philosophy of science, and explanation under constraint

Open to conversations about:

• Early-universe cosmology (inflationary and non-inflationary)
• Philosophy of physics and scientific explanation
• Effective field theory, coarse-graining, and stability
• Methodological tools for theory evaluation
• Where modern cosmology quietly relies on bookkeeping

Clarity beats cleverness. Explanations should earn their work.
