Tech reference

This zone holds engineering-only references that are pulled into the internal AI assistant’s prompt or used by developers when working on the assistant or running ad-hoc SQL against the production database.

It is deliberately small. Most reference material that used to live under /tech has been redistributed by the IA refactor (spec 002):

• API internals → /api
• WWW internals → /www
• Architecture diagrams + datastorage notes + GitHub/DigitalOcean docs → /infra
• External integration deep-dives (FuzeMetrix, Convergence) → /integrations
• Change-request documentation → /business-logic/change-requests

What remains here:

• Code map — a directory-level orientation of the monorepo for new contributors
• Database schema — the canonical MySQL schema reference the assistant reads (relationships, business definitions, common query shapes, and the auto-generated column listings for every table the assistant has SELECT access to)
