C01 What it is
The build, in passes.
Kaha is a voice-first, local-first POS and inventory app, Android first, with a marketing website. Pure TypeScript domain logic (money, cart, tax, order numbers, QR payloads and an intent parser) sits in its own package, and the AI package holds the instructions, tool schemas and agent loop.
