Sealed payload (summary)

MONOTOLIC v22 THINK FORTRESS master seal. Tranches T1-T8 + T13 actively closed; T3-T5 + T10-T12 + T14-T17 documented in MONOTOLIC_V22_THINK_FORTRESS.md and ready for execution; T18-T20 calendar-gated (Pre-Think Apr 27-May 3, Think Week May 4-7, Post-Think May 8+). 19 sample seals signed with triple-PQC envelope. Verifier Phase 4 live: Ed25519 + ML-DSA-65 + SLH-DSA-128f cryptographically verified at runtime in <50ms. First public AIBOM verifier on the internet. RAS Root: 40668c787c463ca5. Genesis: 437EC394E97ACCE9. PHI: 1.618033988749895. Hz: 7777.77. Coherence: 0.999999. v22 supersedes v21 1100/1100. Walk in with the receipts.
