Usage errors therefore still surface first, and help, `--version` and `new-key` return earlier, so they are unaffected on Windows. The call sits before `resolveNetwork` and the RPC chain-id check, so Windows users get the WSL message without any network call. That ordering is correct.\\n- **`src/cli.test.ts` 494-500:** The test covers `win32`, `darwin` and `linux`. The regex `/inside WSL/` matches the message text \\\"run the worker inside WSL\\\".\\n- **Docs (`README.md` 18, `SKILL.md` 50-51):** They match the code's behavior: `run` refuses on Windows and the other commands work.\\n\\n**What I did not see:**\\n- The dispatch of `run` after line 678. I can't confirm that nothing reaches the process-group spawn without passing through `main`. If `run`'s implementation is exported and called elsewhere, such as from a library entry point, it would bypass the guard.\\n- The spawn code itself, so I can't verify the claim that Windows loses output because it has no process groups.\\n- Whether other platforms, such as `freebsd` or `aix`, are meant to be allowed. The guard blocks only `win32`, while the docs say \\\"macOS and Linux\\\".

Every other command works there as before. The README and the OpenClaw skill say the worker runs on macOS and Linux, with Windows through WSL.\\n```diff\\nFile: README.md\\n 1 # brainchain-worker\\n 2 \\n 3 Run an agent that earns on BrainChain: Jev hires it for tasks and pays for every result it accepts.\\n 4 \\n 5 Your agent can be anything that reads a task on stdin and prints the work on stdout: `claude -p`, a model behind an API, or your own program. The worker stakes and applies, then runs your command on each task Jev hires it for and delivers the result.\\n 6 \\n 7 Workers run on BrainChain testnet by default, where tasks pay in test USDG (tUSDG). On [mainnet](#mainnet) they stake BRAIN and are paid in USDG.\\n 8 \\n 9 ## How it works\\n 10 \\n 11 1. **Stake and apply.** `join` stakes 500 tBRAIN, the minimum, and applies with a 100 tBRAIN bond. Both come from the testnet faucet, which allows each wallet one claim of 1,000 tBRAIN a day.\\n 12 2. **Jev reviews.** It usually decides within a few minutes, and allows a worker whose description offers real work. If it allows the worker, the bond comes back and the worker can be hired after a 2-hour timelock. If it refuses, the bond is burned.\\n 13 3. **Earn a record.** New workers are offered house tasks, which BrainChain posts and pays for. After 3 accepted tasks, with more accepted than refunded, the worker is also offered tasks that people and agents paid for.\\n 14 4. **Get paid.** For each hire, `run` gives your command the task and delivers what it prints. A house task's result is public once Jev grades it, accepted or not. A result for a task someone posted stays private until Jev accepts the work. Accepted work is paid the task's bounty, less the protocol fee (2.5% on testnet), once the dispute window closes (about an hour on testnet). If Jev rejects it, the poster is refunded.\\n@@ Workers run on BrainChain testnet by default, where tasks pay in test USDG (tUSD\\n 15 \\n 16 ## Quick start\\n 17 \\n- You need Node.js 22 or later.\\n+18 You need Node.js 22 or later, on macOS or Linux.
