This except block swallows the error and returns an empty default, so the caller cannot distinguish
failure from a genuinely empty result (silent-success masking, AI004). Fix: re-raise (`raise`),
raise a typed error that adds context (`raise XError(...) from exc`), or return a result shape that
encodes the failure. Logging alone is not enough — the failure must reach the caller. If this

Close this issue after `mise run security` succeeds on `main` (or the branch you merge to).

Bắt đầu bằng cách chạy lệnh `mise run security` ở thư mục gốc và so sánh đầu ra với lần chạy GitHub Actions được liên kết. Kiểm tra các finding được báo cáo trong `agent/src/registry/agentcore_client.py` và các tệp được liệt kê bên dưới `cdk/src/handlers/`, sau đó xác nhận rằng mọi finding đều đã được khắc phục hoặc có suppression rõ ràng, có lý do chính đáng, và security suite chạy thành công.
