# E-002 — Crystallization fidelity and cost

## Design

Run one agentic realization repeatedly against a stable lab version until
realization is stable, crystallize it, then execute the descendant with no model
involvement across every lab version the ancestor was run against.

## Outcomes recorded

Oracle set of descendant vs ancestor · verdict agreement per lab version ·
execution cost ratio (tokens, wall time) · whether human authorship of assertions
was required.

## Decision rules

- Descendant oracle set is not a superset of the ancestor's → H-003 falsified.
- Any verdict disagreement on the same lab version → H-003 falsified.
- Cost ratio ≥ 1 → thesis intact, product rationale is not. Record plainly rather
  than quietly.
