Epic 7 — IDAM core implementation (GoTrue proxy)

GitHub issue: #279

Catalog: Epics 1–9 | Theme: IDAM (Epics 6–9)

Overview

Implement the IDAM core as a GoTrue proxy: same API surface as the reference spec (token, user, verify, signup, factors, etc.), with optional server-side session store (e.g. Redis). The implementation can be BRRTRouter-generated from the reference OpenAPI or a shared library that IDAM services depend on.

Scope

• IDAM core service: Skeleton (BRRTRouter codegen from reference spec or shared library); config for GoTrue base URL and path prefix.
• GoTrue client: Integrate with Supabase GoTrue (all core paths from IDAM GoTrue API Mapping §3.1).
• Optional: Session/Redis store for server-side session state.
