# ADR-002 — Modular monolith for MVP

## Status

Accepted

## Context

The product has several domains and background work but must remain easy to self-host on Docker and Unraid.

## Decision

Use one repository and one application codebase with explicit domain packages. Deploy separate web and worker process roles backed by one PostgreSQL database.

## Consequences

- simpler deployment, transactions and development;
- domain boundaries remain testable;
- no network overhead between premature services;
- future extraction remains possible through defined ports;
- discipline is required to avoid framework/domain coupling.
