What

pr-title.yml now requires the scope in a pull request title: type(scope): description. The optional ! stays after the scope. The header comment, the error message, README.md, CONTRIBUTING.md and CHANGELOG.md (Unreleased) say the scope is required, with an example. test/pr-title.test.mjs covers the new rule.

Old pattern:

^(feat|fix|docs|chore|ci|build|refactor|test|perf|revert|style)(\([a-z0-9][a-z0-9._/-]*\))?!?: [^[:space:]]

New pattern:

^(feat|fix|docs|chore|ci|build|refactor|test|perf|revert|style)\([a-z0-9][a-z0-9._/-]*\)!?: [^[:space:]]

The title still reaches the shell through env: only; the job still takes no input, checks nothing out and runs no action.

Why

Merged commits on main read both perf: ... and perf(parser): .... We want every pull request title, and so every squash commit, to read type(scope): description. Each repo takes the rule when its pin of this workflow moves to a reference that carries this change; nothing changes in a caller before that.

Proof

• harness gate github-profile --fast: passed, 4 of 4 (actionlint, node --test, em-dash scan, package lists).
• test/pr-title.test.mjs against the old workflow: 4 failures (the no-scope titles are accepted, and every type with no scope). With the change: 53 pass, 0 fail.
• Cases run through the workflow's own step:
  • refused: fix: keep the escape sequence in OBX-5, feat!: require Node 22 or later, chore: bump actions/checkout from 7.0.1 to 7.1.0, and each of the 11 types with no scope;
  • accepted: fix(parser): keep the escape sequence in OBX-5, refactor(reader)!: one fail-closed reader, each of the 11 types with a scope;
  • accepted: chore(release): version packages, which release.yml writes (read from the file and run through the step);
  • accepted: chore(deps): bump actions/checkout from 7.0.1 to 7.1.0 and the capitalised chore(deps): Bump ..., the shape Dependabot writes with prefix: chore and include: scope.
• The sibling Dependabot configs read (hl7, x12, fhir) all set prefix: chore and include: scope.

Choices

• The anchor-mutation test now uses a title that has a scope inside the quoted text, because without a scope even the loosened pattern refuses the old example.
• To undo: revert this commit; the old pattern is in the diff.
