## ADDED Requirements

### Requirement: Local Compose runs FrankenPHP application alongside PostgreSQL

The local Docker Compose stack SHALL include a FrankenPHP application service built from the project Dockerfile, dependent on a healthy PostgreSQL service, exposing the application on port 8000 (or documented equivalent). FrankenPHP MUST run in regular mode (ADR-006).

#### Scenario: Developer starts full local stack

- **WHEN** a developer runs `docker compose up -d` with the application service enabled
- **THEN** PostgreSQL and the FrankenPHP app containers MUST become healthy
- **AND** `GET /up` on the app port MUST return HTTP 200

#### Scenario: App waits for database readiness

- **WHEN** the application service starts
- **THEN** it MUST depend on the PostgreSQL healthcheck succeeding before becoming ready

### Requirement: Runtime PHP version is canonically 8.4

Docker, CI, and project documentation MUST treat PHP 8.4 as the canonical runtime for this MVP. Statements that require PHP 8.5+ MUST NOT remain in project docs while the runtime image uses 8.4.

#### Scenario: Dockerfile pins PHP 8.4

- **WHEN** the production/runtime image is built
- **THEN** the FrankenPHP base image MUST use PHP 8.4

#### Scenario: Documentation matches the runtime

- **WHEN** a contributor reads the README requirements
- **THEN** the documented PHP version MUST be 8.4 (compatible with Composer `^8.3`)
