- A pull request that touches `public/app.js`, `public/style.css`, `src/engine.js`, `src/routes.js`, `src/commands.js` or a `test/lib/` helper that a browser test imports now runs every gating browser test in the PR gate, over eight browser shards as on main. Before, the gate ran only the browser tests matched by file name or by a literal in the changed code: 24 of 405 for a one-line `public/app.js` change. Other diffs keep that selection, and a `test/lib/` helper that only unit tests import still widens nothing (Feature #368).
