+# Phase 26 Summary
+
+Commercial Roadmap Realignment is foundation-complete.
+
+## Completed Units
+
+1. Package-neutral source contracts.
+2. External peer profile support model.
+3. Maintained peer selection policy.
+4. External peer lab environment contract.
+5. Digest-covered external peer artifacts.
+6. External peer run commands.
+7. External peer commercial readiness aggregation.
+8. Commercial release gate alignment.
+9. Migration notes and public label cleanup.
+10. Final realignment status and documentation.
+
+## Current State
+
+`SigtranCommercialRoadmapRealignmentStatus.GetReport().FoundationReady` is expected to be true.
+
+The SDK public contracts now describe external peers, maintained peers, interoperability evidence, and commercial readiness without binding source names to a specific peer package.
+
+## Production Claim Boundary
+
+The realignment foundation does not make the SDK commercially ready by itself. Commercial release remains blocked until a maintained external SIGTRAN peer run produces passing PCAP, peer logs, SDK traces, configuration, comparison evidence, and release artifacts with digest coverage.
