Product strategy Tier 3 items are not v1 commitments. Phase 22 promotes each area from deferred to experimental with a documented golden path or minimal runtime.

Runtime telemetry (RuntimeTelemetry, mission traces, trigger metrics) remains the production
observability surface.
- LLVM as primary deploy path (interpreter stays default)
- Production blockchain adapters (
spanda-ledger-ethereum, etc.) - Full world-model / knowledge-graph semantics
- Production twin cloud SaaS (hosted multi-tenant service; OSS Control Center backend is Experimental — see twin-cloud.md)
- Full fleet planning / consensus
- Full DDS middleware (current DDS adapter is UDP JSON shim)
- Full ROS replacement
- Complete self-hosted compiler
