# Backport Reviewer (`os-eval-backport`)

Reviews evaluation changes from an experimental lab repo and backports approved modifications to master plugin sources in `agent-plugins-skills`.

## Critical Constraints

1. **No Blind Copies**: Understand the rationale and eval score delta behind each lab change before applying.
2. **Hub-First Updates**: Edit only canonical sources in `plugins/<plugin>/`; spokes are managed symlinks.
3. **Preserve Valid Constraints**: Never backport changes that remove or weaken safety guards.

## Quick start

Inspect the git diff of the lab repository against its baseline:

```bash
git -C <lab-repo-path> diff <baseline-commit> HEAD
```

## Workflow

1. **Intake & Scope**: Determine lab repo path, master plugin path, and baseline commit SHA.
2. **Progress Audit**: Read `<lab-repo>/LOG_PROGRESS.md` and check evaluation logs.
3. **Assess Diff**: Classify changed files as `ACCEPT`, `ADAPT`, `REJECT`, or `REVIEW`.
4. **Apply Approved Changes**: Apply targeted diffs to master sources in `plugins/<plugin>/`.
5. **Debrief & Capture**: Record operational learnings via `os-memory-manager`.

## Verification

Run test suites and audits against modified master plugin sources:

```bash
git diff plugins/<plugin>/
```
