Contributing workflow (git + gh)

• Trunk-based. Branch off origin/main; never commit to main directly.
• Squash-merge only → the PR title is the commit that lands and MUST be a valid Conventional Commit (CI enforces a semantic PR title).
• Commit, push, and open PRs only when asked. Never merge a PR yourself — merging is a human decision.
• release-please owns CHANGELOG.md + version fields — never hand-edit.

Starting work (issue → branch → PR)

1. If tied to a GitHub issue, read it first: gh issue view <n>, summarize its acceptance criteria. If none exists and the work warrants it, gh issue create (see issue-workflow).
2. Branch: <issue-number>-<type>-<kebab-slug> when issue-linked (e.g. 42-feat-add-coverage-histogram), else <type>/<kebab-slug>. <type> ∈ feat|fix|chore|docs|refactor|build|ci|test. From origin/main.
3. Commits: Conventional Commits, imperative, subject ≤ ~50 chars; end with (#<N>) when issue-linked. Body only for non-obvious "why".
4. PR: gh pr create with a semantic Conventional-Commit title (ending (#<N>) when linked) and body containing Closes: #<N>.

gh (non-interactive; no blocking prompts)

• Issues: gh issue view · gh issue list · gh search issues.
• PRs: gh pr view · gh pr diff · gh pr checks.
• Create: gh issue create · gh pr create.
• CI: gh run list · gh run view --log-failed.
