Problem 13 · Early Universe

CONSISTENT

BBN concordance

What's wrong (standard view): Five measurements agree on 26% DM.

ISST status

Current status: CONSISTENT

On Branch A with conformal-invariant radiation, the source of Ψ vanishes (T = 0), so G is constant across BBN. Standard BBN reaction-network output inherited.

Where this is documented

Paper §7.3

This is an auto-summary of the canon entry. The full derivation lives in the referenced section of the lab's manuscript and working notes; a hand-enriched page may be added here in a later pass.

What would prove this wrong

Kill conditions

Per-problem kill conditions are recorded with each derivation in the ISST manuscript. The site-wide kill conditions (right-hand sidebar) cover the framework-level commitments that, if violated, would invalidate all DISSOLVED and PARTIAL claims simultaneously.
