Codex Remote Hub: Secure Phone-to-IDE Bridge with Multi-Layer Defense Pipeline

Prior art declaration for Codex Remote Hub, a REST-based bridge server enabling secure remote control of an IDE (Claude Code / VSCode) from a mobile device (Android APK). Implements a 4-specialist defense pipeline: (1) Sentinelle Active with 7 semantic threat vectors and kill switch, (2) Brain IDE hybrid classifier combining a deterministic 6-layer rule engine with a 3-model sklearn ML ensemble, (3) Memory Guard preventing persistent state modification from remote devices, (4) Production Gate requiring PIN authentication for non-chat commands. Includes a file-based chat bridge protocol that relays phone messages to an active Claude Code session at zero additional API cost. Part of the AOED-RAM Guardian network.
