It classifies the diff into core, core tests, extensions, extension tests, apps, docs, release metadata, and tooling, then runs the matching typecheck/lint/test lanes. Public Plugin SDK and plugin-contract changes include extension validation because extensions depend on those core contracts. Release metadata-only version bumps run targeted version/config/root-dependency checks instead of the full suite, with a guard that rejects package changes outside the top-level version field. - Import-light unit tests from agents, commands, plugins, auto-reply helpers, `plugin-sdk`, and similar pure utility areas route through the `unit-fast` lane, which skips `test/setup-openclaw-runtime.ts`; stateful/runtime-heavy files stay on the existing lanes. - Selected `plugin-sdk` and `commands` helper source files also map changed-mode runs to explicit sibling tests in those light lanes, so helper edits avoid rerunning the full heavy suite for that directory. - `auto-reply` has three dedicated buckets: top-level core helpers, top-level `reply.*` integration tests, and the `src/auto-reply/reply/**` subtree. This keeps the heaviest reply harness work off the cheap status/chunk/token tests.
