2026-07-24 – Toolchain Control Plane

Summary

Named the Toolchain Control Plane pattern: ecosystems should own install, version pinning, health, repair, and upgrade in the official entrypoint. Community version managers are a bridge, not the end state. Flutter is the primary case study.

Naming: TCP (canonical acronym), TCoP (alternate when disambiguating from Transmission Control Protocol), TCF (Toolchain Framework — toolkit to generate/validate compliant planes).
