Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Denial of Service: Parsing extremely large floating-point literals with std::stod can throw unhandled out-of-range exceptions, crashing the entire database process. This can be triggered remotely by sending malformed JSON payloads.

Denial of Service: A memory leak in the JSON.DEBUG KEYTABLE-CORRUPT administrative subcommand allows authenticated users to exhaust system memory. The subcommand failed to restrict execution via proper ACLs and lacked robust handle lifecycle management.
