# Node + tsx "__name is not a function" crash

## Summary
Running Clawdbot via Node with `tsx` fails at startup with:

```
[clawdbot] Failed to start CLI: TypeError: __name is not a function
    at createSubsystemLogger (.../src/logging/subsystem.ts:203:25)
    at .../src/agents/auth-profiles/constants.ts:25:20
```

This began after switching dev scripts from Bun to `tsx` (commit `2871657e`, 2026-01-06). The same runtime path worked with Bun.

## Environment
- Node: v25.x (observed on v25.3.0)
- tsx: 4.21.0
- OS: macOS (repro also likely on other platforms that run Node 25)

## Repro (Node-only)
```bash
# in repo root
node --version
pnpm install
node --import tsx src/entry.ts status
```

## Minimal repro in repo
```bash
node --import tsx scripts/repro/tsx-name-repro.ts
```

## Node version check
- Node 25.3.0: fails
- Node 22.22.0 (Homebrew `node@22`): fails
- Node 24: not installed here yet; needs verification

## Notes / hypothesis
- `tsx` uses esbuild to transform TS/ESM. esbuild’s `keepNames` emits a `__name` helper and wraps function definitions with `__name(...)`.
- The crash indicates `__name` exists but is not a function at runtime, which implies the helper is missing or overwritten for this module in the Node 25 loader path.
- Similar `__name` helper issues have been reported in other esbuild consumers when the helper is missing or rewritten.

## Regression history
- `2871657e` (2026-01-06): scripts changed from Bun to tsx to make Bun optional.
- Before that (Bun path), `pnpm clawdbot status` and `gateway:watch` worked.

## Workarounds
- Use Bun for dev scripts (current temporary revert).
- Use Node + tsc watch, then run compiled output:
  ```bash
  pnpm exec tsc --watch --preserveWatchOutput
  node --watch dist/entry.js status
  ```
- Confirmed locally: `pnpm exec tsc -p tsconfig.json` + `node dist/entry.js status` works on Node 25.
- Disable esbuild keepNames in the TS loader if possible (prevents `__name` helper insertion); tsx does not currently expose this.
- Test Node LTS (22/24) with `tsx` to see if the issue is Node 25–specific.

## Next steps
- Repro on Node 22/24 to confirm Node 25 regression.
- Test `tsx` nightly or pin to earlier version if a known regression exists.
- If reproduces on Node LTS, file a minimal repro upstream with the `__name` stack trace.
