2026-07-24 – Toolchain Control Plane

Summary

DevCentr now documents and surfaces the Toolchain Control Plane pattern: ecosystems should own pinning and environment integrity in the official entrypoint. The Flutter management page leads with an advisory when that plane is missing and lists community bridges.

Application

  • app/src/modules/ui/advisory_banner.d — reusable top-of-page advisory

  • app/src/modules/ecosystems/ — model, SDL loader, EcosystemManagerPanel

  • app/src/modules/languages/flutter.sdl, updated node.sdl (unifiedControlPlane)

  • UI: pageFlutter (index 9), home card + sidebar Flutter

Documentation

  • ROOT: toolchain-control-plane.adoc; vision hierarchy/policy updates

  • Spec: ecosystem-management.adoc; definition-files unifiedControlPlane section

  • Companion philosophy + Flutter how-to in general-knowledge
