 - `OPENCLAW_HEAVY_CHECK_LOCK_SCOPE=worktree <local-heavy-check command>`: keeps heavy-check serialization inside the current worktree instead of the Git common dir for commands such as `pnpm check:changed` and targeted `pnpm test ...`. Use it only on high-capacity local hosts when you intentionally run independent checks across linked worktrees.
 - `pnpm test`: routes explicit file/directory targets through scoped Vitest lanes. Untargeted runs are full-suite proof: they use fixed shard groups, expand to leaf configs for local parallel execution, and print the expected local shard fanout before starting. The extension group always expands to the per-extension shard configs instead of one giant root-project process.
 - Test wrapper runs end with a short `[test] passed|failed|skipped ... in ...` summary. Vitest's own duration line stays the per-shard detail.
