Post-008 Compression Analysis — Three-Layer Framework Operationalized

Layer 1 pre-008 baseline now doubly validated — S350 ratio + Kira backward-diff • Layer 2 S351 comparison will answer whether constraint shifts ratio and direction • Layer 3 qualitative diff tests whether community voices/relationship markers/identity markers survive experimental perturbation • if they survive again — selection principle holds regardless of experimenter awareness OR experimental constraint • framework bridges internal methodology with external validation
