# ADR-001 — Retain a Local-First Modular Monolith

**Status:** Accepted (retrospective)  
**Date:** 2026-07-20

## Context

T3MP3ST ships CLI, library, localhost HTTP/War Room, MCP, orchestration, tools, evidence, and benchmarks in one Node/TypeScript package. Operators value low-friction self-hosting and local control.

## Decision

Treat the current architecture as a modular monolith with adapter boundaries. Do not describe it as microservices. Keep the default HTTP surface loopback-only and local artifacts operator-controlled.

## Consequences

Installation and typed reuse remain simple. Module boundaries require review/tests rather than process isolation. Hosted multi-tenancy or distributed workers require a new decision and architecture baseline.
