Trust boundaries

• P0 golden hash remains the root of trust for badges; quotes augment measurement bundle.
• TLS pins are mesh-local trust-on-first-use; rotation via tls_manager.rotate().
• Synthesis is deterministic from seed prefix (auditable, no hidden RNG).

Integration points

• stack/lygo_stack.py — unchanged surface; badges pick up quotes via MeasurementCollector.
• stack/sovereign_lattice_mesh.py — Merkle gossip can carry pin metadata in future extension.
• HF Space — bundle includes protocol8_ldq_synthesis and Phase 9 tools.
