ADR-002: Branch Model

Publishable summary of this architecture decision.

Decision

The default branch model is main + develop, with documented exceptions for active clients, Moodle upgrades, and legacy projects.

Branch	Purpose
main	production-ready code and releases
develop	integration before production
feature/*	feature work
hotfix/*	urgent fixes from main
release/*	optional, mostly for legacy or Moodle flows

Moodle upgrade branches and client branches may remain when they reduce operational risk.
