# Data Model: Quality Gates & Code Hygiene

**Feature**: 031-quality-gates-hygiene
**Date**: 2026-03-11

## Overview

This feature has no new domain entities. It modifies configuration files, documentation, and refactors existing code for lint compliance. No data model changes.

## Configuration Artifacts

### Vitest Coverage Config (vitest.config.ts)

New `test.coverage` block:
- `provider`: "v8"
- `enabled`: true
- `thresholds.lines`: 70 (initial, auto-ratchets)
- `thresholds.branches`: 60 (initial, auto-ratchets)
- `thresholds.autoUpdate`: true

### Biome Config (biome.json)

New rules under `linter.rules`:
- `complexity.noExcessiveCognitiveComplexity`: error, maxAllowedComplexity: 15
- `a11y.noNoninteractiveElementInteractions`: error

### Check Script (package.json)

Updated `check` script adds `pnpm audit --audit-level=high` step.

## New Component

### StopPropagation Wrapper (apps/web/src/components/)

A small presentational component that wraps children in a `<div>` with `onClickCapture` to stop propagation, replacing the current pattern of `<div onClick={e => e.stopPropagation()}>` that requires biome-ignore comments. Exact implementation TBD during task execution — alternatives include using `role="presentation"` or restructuring the click handling logic in the parent row.
