[error-path]

What and why

How it was tested

• npm run check passes
• npm run build:action run and action/dist committed (if src/ changed)
• docs/specs updated (if a contract in src/domain/types.ts or the policy changed)

Summary by CodeRabbit

• New Features
  • Added a benchmark that evaluates review facts against reviewer engagement and later fixes across six repositories, with summaries of results, priority tiers, and changes from a baseline.
  • Added commands to collect benchmark data, build and label the evaluation corpus, and generate reports.
• Documentation
  • Added benchmark instructions, study findings, and design and implementation notes.
• Tests
  • Added coverage for benchmark analysis, labeling, reporting, and data handling.

Walkthrough

Adds a benchmark harness that selects pull requests from six repositories, builds outcome labels, and reports fact metrics, priority rates, and baseline drift. The change also adds tests and study documentation. It does not change detectors.

Changes: Outcome-label benchmark

Layer / File(s)	Summary
Select and reconstruct the corpus bench/outcomes/lib.ts, bench/outcomes/run.ts, docs/specs/2026-10-23-outcome-labels-design.md, docs/superpowers/plans/2026-10-23-outcome-labels.md, docs/experiments.md, tests/bench/outcomes-lib.test.ts	Selects eligible pull requests, handles merge shapes, reconstructs pull request ranges, and builds corpus records and briefs.
Label and evaluate outcomes bench/outcomes/lib.ts, bench/outcomes/run.ts, docs/specs/2026-10-23-outcome-labels-design.md, docs/superpowers/plans/2026-10-23-outcome-labels.md, docs/experiments.md, tests/bench/outcomes-lib.test.ts	Derives review, fix, revert, and coupling labels. Computes lifts, conclusions, priority rates, concentration, and drift.
Run and report the evaluation .gitignore, bench/outcomes/*, docs/experiments.md, docs/specs/2026-10-23-outcome-labels-design.md, docs/superpowers/plans/2026-10-23-outcome-labels.md	Adds CLI orchestration, benchmark documentation, experiment results, a refreshed baseline, and the generated Markdown report. The .gitignore excludes results.json.

Merge Risk: Moderate · up to 6cb32

This adds a benchmark harness only, so product behavior is unaffected. The label step can undercount later fixes for older PRs, which could bias the recorded fact verdicts. A deleted reviewer account can crash labeling. The committed results report and several docs are stale. Fix the history cap and null-user handling and regenerate the report before relying on the results.
