- BearSSL replaced with mbedTLS (TLSv1.3 passes Cloudflare) - 8MB frame cap + truncation-proof gateway op/seq scanner - Thread-safe compat, locked logging, atomic config with template - Daemon keeps last-good config, persistent presence timer - 256B token buffers, weak-libc shims, portable build preflights - Tests: gateway spoof + OOM cases pass Still open: display names fall back to titleId in sandbox, cover art needs shared Discord app assets. Backend fully functional.
