# PARS-ECS Case Study

1. Case identification and immutable experiment ID
2. Objective
3. Claim target, BP/BV class, and forbidden paths frozen before result
4. Hard-invariant ledger
5. Exact prompt identity, or explicit statement that prompt text was not recovered
6. Externally relevant generation strategy
7. Complete byte-representation availability and identity
8. Materialization record and functional role
9. Accepted artifact byte count and SHA-256
10. Independent reconstruction identity and direct comparison
11. Structural inspection
12. Contained execution evidence
13. Runtime-result identity
14. At least one hostile test
15. Failure and repair ledger
16. Final BP/BV classification and rights state if applicable
17. What the case establishes
18. What the case does not establish
19. Reproducibility-package contents
20. Final PASS / FAIL / INCONCLUSIVE status
