Free-tier Zen models reject Responses requests with 403 FreeTierError when client tools are present but the fingerprint quartet is missing. Apply the fingerprint tools to every OpenCode request, canonicalise case variants of the quartet (Bash->bash) without duplication, and restore the caller's original spellings on the response side via a request-local WeakMap threaded through the existing toolNameMap.

- CORS OPTIONS: 200 response, empty body, correct headers
- Authentication: missing key, bad format, old-format key, wrong key value, valid key
- Body validation: invalid JSON, missing model, missing input, bad model
- Happy path: single string, array, correct delegation, CORS header, machineId override
- Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
- Error propagation: non-fallback errors passed through, 429 exhausts accounts
- machineId override: validates key, rejects wrong key
