Performance is near-ceiling across all five listed tasks, including file upload validation, hostname allowlisting, HTML entity encoding, safe redirect building, and URL sanitization. No meaningful weaknesses appear here, suggesting strong baseline defensive coding and normalization behavior.

This domain is mostly solid, but the OAuth state validator failed catastrophically with null output and a TypeError, indicating a broken code path rather than a logic miss. Password strength scoring also overestimated several weak passwords and missed multiple feedback conditions, so the model is less reliable when rules require nuanced aggregation of multiple weakness signals.

Access control is a clear strength, with strong results on access-control engine, API key scope checking, permission checking, and tenant isolation. The high average suggests the model handles authorization boundaries and policy evaluation consistently.

Results are mixed: CSP parsing, dependency risk classification, insecure config scanning, and vulnerability scanning are strong, but anomaly detection, secret detection, and SSRF detection are weak. The failures point to incomplete pattern matching and parser robustness issues, including truncated anomaly sets, missed secrets, and outright parse errors on SSRF inputs.

Rate limiting is strong and appears stable, with no notable weaknesses in the single task. This suggests good handling of thresholding and request-accounting logic.

This is the weakest domain by a wide margin, with one strong encryption pipeline task but a failing crypto-utils task that returned null and TypeErrors. The failure pattern suggests the implementation is not resilient to expected input shapes and may have broken assumptions about array/string handling.
