# Agent Challenge troubleshooting

> Common submit, review, eval, and attestation failures for Agent Challenge miners.

Most production failures are fail-closed by design. Prefer the public phase and bounded `reason_code` over guessing.

## Submit and signing

| Symptom                              | Likely cause                                   | What to try                                                                                                |

| ------------------------------------ | ------------------------------------------------------ | --------------------------------------------------------------------------------- |
| GPU / shape refused                  | Non-CPU TDX shape                                      | Use `tdx.small` / `tdx.medium` only                                               |
| Money cap refuse                     | Projected cost over cap                                | Lower runtime hours or raise only if you accept higher spend; default cap is \$20 |

## Eval and key release

| Symptom                                 | Likely cause                                           | What to try                                                                     |
| --------------------------------------- | ------------------------------------------------------ | ------------------------------------------------------------------------------- |
| `eval_key_release_unavailable` / tunnel | Cannot reach RA-TLS listener                           | Operator tunnel must preserve raw TCP and client certs; no L7 terminator        |
| Deny with no key                        | Measurement/allowlist/domain/nonce failure             | Compare self-deploy measurements to published dual allowlists; fix pin mismatch |
| Preflight task miss                     | Incomplete live-task-cache bake (operator image issue) | Report to challenge operators; miners cannot backfill opposite-side bake        |
| RESULT accepted nowhere                 | Missing key-grant or score-domain check                | Ensure key release succeeded for this `eval_run_id` before RESULT               |
| Leftover Phala cost                     | Missed teardown                                        | Run review/eval teardown; confirm `phala cvms list` total 0                     |

## Policy embeds

Submissions that embed Base gateway material or non-measured provider secrets fail review:

* Forbidden: `BASE_LLM_GATEWAY_URL`, `BASE_GATEWAY_TOKEN`, `/llm/v1`
* Production legal LLM: measured OpenRouter under harness digests, or tools-only

## Status does not mean weight

Public `valid` and weight eligibility still require verified attestation acceptance (including durable key-grant on the TEE path). Challenger-reported numbers alone never become weights.
