Constant Summary collapse

DEFAULT_SAFE_KEYS =

Keys considered safe to log by default. Application-supplied data like headers or block arguments are excluded to avoid leaking secrets/PII through structured logs. origin is whitelisted because Deadline.from_header enforces ORIGIN_PATTERN so the value can only be [A-Za-z0-9_.-]+. Pass extra_keys: to include additional whitelisted keys.
