# ADR-009: Rename `adapters/` to `integrations/`

**Status:** Accepted
**Date:** 2026-05-04

## Context

The source spec (monorepo-architecture-spec-detailed-v5.md) uses `adapters/cms` and `adapters/api` for Payload and tRPC integration points. Clean Architecture also uses `adapters/` (or `interface-adapters/`) for transport-agnostic controller layer. The name collision is confusing.

## Decision

Use `integrations/` for role-based plug points (Payload and tRPC). Keep `interface-adapters/` for the Clean Architecture controller layer.

**Result:**
```
packages/<feature>/src/
  interface-adapters/controllers/  ← Clean Architecture layer (transport-agnostic)
  integrations/
    cms/                           ← Payload collections/globals
    api/                           ← tRPC routers
```

## Consequences

- No naming collision — intent is unambiguous
- `integrations/` semantically captures "external system integration" better than `adapters/`
- Minor deviation from source spec, documented here as deliberate choice
- All new features follow this naming consistently

## Alternatives Considered

- Keep `adapters/`: Collision with Clean Architecture terminology is confusing
- Use `external/`: Less specific; doesn't convey "Payload and tRPC"
- Rename Clean Architecture layer to `controllers/`: Could work; less standard
