 - `pnpm test`: runs the full wrapper. It keeps only a small behavioral override manifest in git, then uses a checked-in timing snapshot to peel the heaviest measured unit files into dedicated lanes.
 - Unit files default to `threads` in the wrapper; keep fork-only or `forkBatched` exceptions documented in `test/fixtures/test-parallel.behavior.json`.
 - `pnpm test:extensions` now defaults to `threads` via `vitest.extensions.config.ts`; the March 22, 2026 direct full-suite control run passed clean without extension-specific fork exceptions.
-- Files marked `forkBatched` stay on `forks`, but the wrapper batches them into low-concurrency `forks` lanes with `maxWorkers=1` instead of spawning one fresh Vitest process per file. Tune lane count with `OPENCLAW_TEST_UNIT_FORK_BATCH_LANES=<n>`; the old `OPENCLAW_TEST_SINGLETON_ISOLATED_LANES=<n>` alias still works.
