APR-Lite Phases 10.5–10.9: Coalition Topology, Sector Routing, Tenant Unfreeze, Audit Integrity, and Signal Provenance

This note records five phases that completed the substrate’s temporal, jurisdictional, and security hygiene layers. Phase 10.5 introduced coalition topology retention — the substrate’s first structural understanding of multi-tenant interaction patterns. Phase 10.6 established the sector routing rules table as the jurisdictional floor for cross-tenant reads. Phase 10.7 delivered the governed relief path for escalation-triggered tenant freezes. Phase 10.8 implemented per-tenant hash-chain integrity over the governance audit trail. Phase 10.9 closed the cross-tenant signal injection vector through provenance validation at drift signal write paths. Cumulative verified baseline: 205 tests passing across all suites. Zero failures.
