Summary

On Windows, OpenClaw fails to spawn the Claude CLI with Error: spawn claude ENOENT. Every model in the fallback chain fails. Root cause: "claude" is missing from the cmdCommands allowlist used by resolveWindowsCommandShim, so .cmd is never appended and Node's spawn() can't resolve claude.cmd on Windows.

Steps to reproduce

1. Official install script: curl -fsSL https://openclaw.ai/install.sh | bash
2. Install the Claude CLI (Anthropic's claude.cmd shim on PATH).
3. Start OpenClaw and send any message that routes to provider=claude-cli.

Expected behavior

OpenClaw resolves claude to claude.cmd on Windows (same way it already does for npm, pnpm, yarn, npx) and the CLI backend process starts successfully.
Root cause is in src/process/supervisor/adapters/child.ts:
resolveCommand calls resolveWindowsCommandShim({ command, cmdCommands: ["npm","pnpm","yarn","npx"] }) "claude" is not in the list, so the shim returns "claude" unchanged. Node spawn() on Windows can't find .cmd shims without shell: true or an explicit extension → ENOENT.

Fix: add "claude" to that cmdCommands array

Actual behavior

Spawn fails immediately for every model in the fallback chain:

[agent/cli-backend] cli exec: provider=claude-cli model=opus promptChars=984
[process/supervisor] spawn failed: reason=Error: spawn claude ENOENT
[model-fallback/decision] decision=candidate_failed requested=claude-cli/claude-opus-4-7 ... detail=spawn claude
ENOENT
... (repeats for sonnet-4-6, opus-4-6, opus-4-5, sonnet-4-5, haiku-4-5) ...
Embedded agent failed before reply: spawn claude ENOENT
