FDC3 Intent Interoperability on C3
State 014 layers FDC3 context and intent interoperability onto the C3 TraderX runtime and adds a local Sail sidecar demo environment.

nats | service | NATS Broker | Realtime ticker and lifecycle updates via websocket gateway. |
State Notes
- FDC3 integration is additive and frontend-scoped.
- No backend API or schema changes are required for core interoperability behavior.
- Sail sidecar is intentionally outside TraderX ingress to keep concerns separated.
- TraderX-hosted App Directory metadata is intentionally behind TraderX ingress because it describes TraderX-owned apps and routes.
- Sail should aggregate app-directory sources rather than owning every app record locally.
- Degraded mode preserves baseline workflows when DesktopAgent is unavailable.
