Review finding on #112260: the hosted-room member relabel regex was a third hand-copied opener list that missed the frames context_compressor and title_generator already treat as harness input, so a member reply starting with "[System: ..." or "[IMPORTANT: 2 background processes ..." reached peers in its exact trusted shape. agent.prompt_builder.CONTROL_FRAME_OPENERS is now the single source; the gateway regex is built from it and the desktop TS literal mirrors it byte-for-byte.
