Codewhale terminal receipt did not use provider openai

Error message

Codewhale terminal receipt did not use provider openai

What it means

After a successful launch (exit code 0), the harness parses the stream-json terminal receipt and verifies the provider field equals 'openai'. The rollout pins CODEWHALE_PROVIDER/--provider to openai (the Verifiers interception endpoint masquerades as OpenAI), so a different reported provider means the run did not go through the interception path.

Solutions

1. Verify you are running the pinned Codewhale release (check terminal.binary_sha256 in the receipt)
2. Ensure no environment variables override CODEWHALE_PROVIDER in config.resolved_env
3. Confirm the harness argv still passes --provider openai and the binary accepts it
4. Re-install the binary via setup() instead of a custom binary_path

try:
    result = await harness.launch(ctx, trace, runtime, endpoint, secret, mcp_urls)
except RuntimeError as e:
    if "did not use provider openai" in str(e):
        # audit binary_sha256/config env for provider overrides before retrying
        ...
    else:
        raise

When it happens

Trigger: The Codewhale binary completed but its terminal receipt reports a provider other than 'openai' — e.g. the binary overrode the provider, ignored the --provider flag, or a mismatched binary/config routed elsewhere.

Common situations: Running a stale or modified binary that defaults to another provider; environment leakage (a real OPENAI/other provider key causing re-route); binary/config sha mismatch indicating a non-pinned build.

Understand the failure class

Background: "invalid response format", "malformed payload", "missing data field": when an API returns 200 but the response shape is wrong — this error's family across 23 libraries.
