BoxA contract-first platform scaffold for testing a small reusable service kernel before implementing its runtime. is a contract-first platform scaffold that fixes a small service kernel before runtime convenience can blur its boundaries. Scenario packs stay as overlays, and local validation checks their coherence before a runtime exists.
A release candidate passed every gate and failed on contact with production six minutes later. The gates proved compatibility with the target database state; nothing had proved the transition from the state actually running.

Backend-owned contracts only become useful release artifacts once the compatibility tooling is conservative enough to complain about real breakage instead of politely missing it.
