gated-downshift

@AldemarHdez

A software factory for Claude Code, driven in natural language: a conductor runs a ten-station line (spec, decompose, design-record, plan, review, execute, verify, CI, merge) with deterministic gates. A fail-safe hook blocks execution until the upstream chain passes, so cheaper models can safely take over.
