Build

Per-platform setup and build commands are in the root README. This directory holds the build model: what is generated, what is pinned, and what makes a firmware image reproducible.

Document	What it gives you
Tag Firmware Build Reproducibility	Which tags are reproducible, what is committed and checked, what each image records, and how to promote a tag, bump ChibiOS, nanopb or the toolchain
Build worklist	Open gaps and questions in that model
Embedded source layout	How boards, proto-c, tags, bases and loaders fit together in the firmware build

Releasing what the build produces is in docs/release.
