# Legacy Data Connect V1

This directory contains the archived V1 Firebase Data Connect source:

- GraphQL schemas
- connector queries and mutations
- seed and clean scripts
- Data Connect service YAML files

Status:

- Treat this directory as legacy infrastructure.
- Do not use it as the source of truth for new backend work.
- The active backend architecture is V2 and lives under:
  - `backend/command-api`
  - `backend/query-api`
  - `backend/core-api`
  - `backend/unified-api`

Why this was moved:

- The old V1 GraphQL source was being picked up by AI tooling and confusing current V2 implementation work.
- Relocating it under `legacy/` keeps the V1 toolchain available without presenting it as the active backend.
