Fix an AetherSDR bug end-to-end and prove the fix with the agent automation bridge. Use when the user says $fb or /fb ISSUE_NUMBER (e.g. /fb 2211), or asks to "fix bug 2211", "take the next bug", "reproduce and fix issue 3340", or otherwise wants a GitHub issue investigated, root-caused, fixed in a worktree, built, proven via the bridge, and turned into a PR. This is the dogfooding loop for the agent automation bridge — reach for it whenever a UX, meter, transmit, audio, or control bug is reported with an issue number.
