# Feature Specification: Initialize Monorepo Structure

**Feature**: `001-monorepo-setup`
**Created**: 2026-03-06
**Status**: Implemented
**Source**: Migrated from spec/setup-tasks.md

> **Note**: This is a setup task (infrastructure), not a user-facing feature. It establishes the repository structure as a prerequisite for all subsequent development work.

## User Scenarios & Testing

### User Story 1 - Developer can scaffold and build the monorepo (Priority: P1)

A developer cloning the repository for the first time can build both the backend and frontend from a clean checkout with no source code beyond the scaffold.

**Why this priority**: Without a working monorepo structure, no further development or CI work is possible.

**Independent Test**: Clone the repository, run `./mvnw verify` in `backend/` and `npm run build` in `frontend/` — both must succeed against the empty scaffold.

**Acceptance Scenarios**:

1. **Given** a fresh clone of the repository, **When** the developer inspects the root, **Then** separate `backend/` and `frontend/` directories exist alongside shared top-level files (README, Dockerfile, CLAUDE.md, LICENSE, .gitignore).
2. **Given** the `backend/` directory, **When** the developer runs `./mvnw verify`, **Then** the build succeeds with no source code beyond the hexagonal/onion architecture scaffold using Java (latest LTS), Spring Boot, and Maven.
3. **Given** the `frontend/` directory, **When** the developer runs `npm run build`, **Then** the build succeeds with the Vue 3 + Vite + TypeScript + Vue Router scaffold.
4. **Given** the repository root, **When** the developer inspects `.gitignore`, **Then** build artifacts, IDE files, and dependency directories for both Java/Maven and Node/Vue are covered.

### Edge Cases

- What happens when a developer uses an older Java version? [NEEDS EXPANSION]
- How does the scaffold behave with no `.env` or environment variables set? [NEEDS EXPANSION]

## Requirements

### Functional Requirements

- **FR-001**: Repository MUST have a `backend/` directory containing a Java Spring Boot Maven project with hexagonal/onion architecture scaffold.
- **FR-002**: Repository MUST have a `frontend/` directory containing a Vue 3 project with Vite, TypeScript, and Vue Router.
- **FR-003**: Repository MUST include shared top-level files: README, Dockerfile, CLAUDE.md, LICENSE (GPL), and .gitignore.
- **FR-004**: Both projects MUST build successfully from an empty scaffold (no application source code required).
- **FR-005**: `.gitignore` MUST cover build artifacts, IDE files, and dependency directories for both Java/Maven and Node/Vue.

### Key Entities

- **Monorepo**: Single git repository containing both `backend/` and `frontend/` as separate projects sharing a root.

## Success Criteria

### Measurable Outcomes

- **SC-001**: `cd backend && ./mvnw verify` exits 0 on a clean checkout.
- **SC-002**: `cd frontend && npm run build` exits 0 on a clean checkout.
- **SC-003**: All six acceptance criteria are checked off (all complete — status: Implemented).

### Acceptance Criteria (original)

- [x] Single repository with `backend/` and `frontend/` directories
- [x] Backend: Java (latest LTS), Spring Boot, Maven, hexagonal/onion architecture scaffold
- [x] Frontend: Vue 3 with Vite as bundler, TypeScript, Vue Router
- [x] Shared top-level files: README, Dockerfile, CLAUDE.md, LICENSE (GPL), .gitignore
- [x] Both projects build successfully with no source code (empty scaffold)
- [x] .gitignore covers build artifacts, IDE files, and dependency directories for both Java/Maven and Node/Vue
