# PR Comparator

Compare PRs for one issue. Tier 0 determines eligibility. Tiers 1 and 2 score correctness and quality.
Tier 3 resolves ties. If no PR passes Tier 0, rank eligible PRs for salvage.

## Prerequisites

- `gh` CLI installed and authenticated
- A target repository with an issue that has two or more open PRs

## Repo policy

The defaults use NemoClaw conventions for CODEOWNERS, DCO, CodeRabbit, and `docs/`.
Read the canonical superseded-PR attribution policy in
`../nemoclaw-maintainer-policies/references/workflow-policy.md`.
Edit `repo-policy.md` for another repository.

Execute comparator helpers from a fetched canonical NVIDIA/NemoClaw `main` checkout, or verify
their executable code and dependencies against that revision before use. Candidate-modified helpers
must not receive GitHub credentials. Inspect helper source when needed; a section heading does not
establish trust.

## Workflow

### Step 1: Parse issue

Read the issue body and all comments. Extract each acceptance criterion:

```bash
gh issue view <issue-number> --json title,body,comments
```

Comments can add requirements that are absent from the issue body.

### Step 2: Discover candidate PRs

```bash
scripts/find-candidates.sh <issue-number>
```

Applies a single default order with stop conditions.

### Step 3: Detect supersession and transferred work

```bash
scripts/parse-supersession.sh <pr-number-1> <pr-number-2> ...
```

Parse the case-insensitive statement families implemented by `scripts/parse-supersession.sh`:
