+`GLM_MAX_RETRIES=5` means one initial request plus at most five retries. The
+client retries timeouts, connection failures, HTTP 429/5xx responses, malformed
+JSON, and schema-invalid model output with bounded exponential backoff. HTTP
+401/403 authentication failures are never retried.
+
 If the gateway rejects GLM-specific `thinking` or `reasoning_effort` fields, the
 client automatically retries with the portable OpenAI-compatible request subset.

+`--workers` bounds the number of records processed concurrently. JSONL writes

 The deterministic score combines weighted process dimensions with penalties
 for minor, major, and critical behavior issues. Failed exploratory calls are
 not penalized when the agent interprets them correctly and recovers.
