Pass explicit --bot flag with JOBDORI_BOT_ID so release announcements
always go out as the Jobdori bot regardless of local agent-discordbot
current-bot state.
Ship the documented Team Mode security-research capability as an .agents skill and expose /security-research through transition command wrappers.
The exact security-review slug has no reachable history hits; security-research is the documented missing artifact from README and issue #3887.
