Branch Naming

• feature/<topic> - New features
• fix/<topic> - Bug fixes
• refactor/<topic> - Refactoring
• docs/<topic> - Documentation

PR Workflow

# Create branch
git checkout -b <type>/<topic> origin/main

# Make changes, then
pixi run lint
pixi run test-all

# Push and create PR
git push -u origin HEAD
gh pr create --draft --milestone "DART 7.0"

Rule of thumb: run pixi run lint before committing so auto-fixes are included.

Use .github/PULL_REQUEST_TEMPLATE.md and ensure the PR description covers Summary, Motivation, Changes, Testing, Breaking Changes, and Related Issues.

Milestones (Required)

Always set a milestone when creating PRs:

Target Branch	Milestone
main	DART 7.0 (or next major)
release-6.16	DART 6.16.x (current patch)

# Set milestone on existing PR
gh pr edit <PR#> --milestone "DART 7.0"

# List available milestones
gh api repos/dartsim/dart/milestones --jq '.[] | .title'

CRITICAL: Bug Fix Dual-PR

Bug fixes require PRs to BOTH branches:

1. release-6.16 - Current release
2. main - Next release

Steps:

1. Fix on release-6.16 first
2. Cherry-pick to main
3. Create separate PRs for each

CHANGELOG (After PR Created)

After creating a PR, check if CHANGELOG.md needs updating:

Change Type	Update CHANGELOG?
Bug fixes	✅ Yes
New features	✅ Yes
Breaking changes	✅ Yes (in Breaking Changes section)
Documentation improvements	✅ Yes (in Tooling and Docs)
CI/tooling changes	✅ Yes (in Tooling and Docs)
Refactoring (no behavior change)	⚠️ Maybe (if significant)
Dependency bumps	⚠️ Maybe (if user-facing)
Typo fixes	❌ No

Format: - Description. ([#PR](https://github.com/dartsim/dart/pull/PR))

# Example entry in CHANGELOG.md under appropriate section:
- Added AI-native documentation with AGENTS.md and module-specific guides. ([#2446](https://github.com/dartsim/dart/pull/2446))

Code Review

• Address all feedback
• Keep changes minimal
• Update tests if behavior changed
• Run full validation before pushing fixes

CI Loop

gh run watch <RUN_ID> --interval 30

Fix failures until green.
