# Task B3: Hook the validator into pre-commit — Report

## Step 1: Added the hook

Added the following block to `.pre-commit-config.yaml` (lines 46-51), appended to the existing `repo: local` section:

```yaml
      - id: validate-patches
        name: validate patch registry
        entry: Rscript local/validate-patches.R
        language: system
        files: ^local/patches/
        pass_filenames: false
```

The hook was integrated alongside the existing `yaml-file-extension` hook, maintaining consistent indentation and YAML structure.

## Step 2: Verified the hook runs

Ran: `pre-commit run validate-patches --all-files`

Output:
```

validate patch registry..................................................Passed
```

Hook passed successfully (pre-commit is installed in this environment).

## Step 3: Committed

```
git add .pre-commit-config.yaml && git commit -m "ci(patches): validate patch registry in pre-commit"
```

Commit: `912423f ci(patches): validate patch registry in pre-commit`

**Status:** Complete. Hook added, verified, and committed successfully.
