regtable — one register table, many interfaces

Why it surfaced

regtable treats application state as a typed register table rather than a growing command vocabulary, then projects that same table across six interfaces. Its YAML code generation, schema-drift checks, validation hooks, and unusually clear explanation make this a particularly coherent piece of embedded-systems plumbing.

A pure C99, no-allocation library that exposes microcontroller state through a serial CLI, Modbus, MQTT, a browser panel, and a typed Python client.
