# Baseline Project

## Overview

A fixture designed to score Grade A on every v3 quality area (CML, SET, HKV,
RUL, MCP, IMP, CNF) before the Token Efficiency scanner is added. Serves as
the grade-stability canary for the config-audit v4.0 release.

## Purpose

This fixture is the regression canary for the posture scorecard. If a future
scanner change drags any v3 quality area below Grade A on this fixture, the
change is not release-safe.

## Commands

- `npm run build` — Build the project
- `npm test` — Run all tests
- `npm run lint` — Lint source files

## Architecture

Standard Node.js layout with TypeScript under `src/`, unit tests co-located
beside implementation files, and shared config imported via `@import`.

## Conventions

- TypeScript strict mode; no `any`
- Conventional Commits (`type(scope): description`)
- Zero runtime npm dependencies where possible
- Deterministic test fixtures only

## Tooling

- Node.js ≥ 18
- `node:test` framework for unit tests
- `node --test 'tests/**/*.test.mjs'` runs the full suite

## Shared Patterns

Shared conventions and helpers are documented in an imported file to keep the
top-level stable-prefix content cache-friendly under Opus 4.7.
