merge-queue-test

Experimentation repo for GitHub Merge Queue before enabling it on ndc-hub.

Purpose

Validate merge queue behavior in a low-risk environment:

• Happy path: single PR queued and merged
• Batching: multiple PRs queued simultaneously
• Batch failure: one bad PR ejected, others continue
• Conflict handling: two PRs touching the same file
• Stacked PRs: base must merge before stacked can be enqueued

Repo Structure

.github/workflows/ci.yml   # CI workflow (uses GitHub-hosted runners)
src/calculator.kt          # Sample source file — modify in PRs to create conflicts
SETUP.md                   # Branch protection configuration steps
SCENARIOS.md               # Test scenarios to run

Quick Start

1. Follow SETUP.md to enable merge queue on main
2. Run scenarios in SCENARIOS.md in order
3. Record observations — then apply learnings to ndc-hub
