through the real `run.ts` / `compact.ts` paths; helper-only tests are not a
sufficient substitute for those integration paths.
- Pool note:
- OpenClaw uses Vitest `vmForks` on Node 22, 23, and 24 for faster unit shards.
- On Node 25+, OpenClaw automatically falls back to regular `forks` until the repo is re-validated there.
- Override manually with `OPENCLAW_TEST_VM_FORKS=0` (force `forks`) or `OPENCLAW_TEST_VM_FORKS=1` (force `vmForks`).
- OpenClaw uses Vitest `forks` by default for unit shards.
- `pnpm test` also defaults to `--isolate=false` at the wrapper level for faster file startup.
- Opt back into Vitest file isolation with `OPENCLAW_TEST_ISOLATE=1 pnpm test`.
- `OPENCLAW_TEST_NO_ISOLATE=0` or `OPENCLAW_TEST_NO_ISOLATE=false` also force isolated runs.
- `OPENCLAW_TEST_VM_FORKS=1` remains an opt-in experiment on Node 22, 23, and 24 only.

- Uses Vitest `vmForks` for faster file startup.
- Uses adaptive workers (CI: 2-4, local: 4-8).
- Uses Vitest `forks` for deterministic cross-file isolation.
- Uses adaptive workers (CI: up to 2, local: 1 by default).
- Runs in silent mode by default to reduce console I/O overhead.
- Useful overrides:
- `OPENCLAW_E2E_WORKERS=<n>` to force worker count (capped at 16).
