 When guiding `bdrive init`, detect existing knowledge tooling and connect it instead of blind-syncing the folder. Two rules govern every case:
 
 - **One transport per folder.** Never sync a folder that has another writer. Git-tracked paths: a teammate's `git pull` or branch switch rewrites files with older content, and sync broadcasts that as a fresh edit — silently reverting the team's latest pages. A gbrain brain root: every private capture and overnight enrichment would become team-visible, and each member's cron rewriting the same pages fills the project with conflict copies. Moving a folder from git to beardrive is a **handoff**: `git rm -r --cached <dir>` + add `<dir>/` to `.gitignore`, stage the change but let the user commit it (teammates then pull and re-init; identical content converges with no conflicts). If they want a git record anyway, offer **one-way snapshots** (a scheduled job commits the synced folder's state to an archive branch — git only ever reads the folder) and note that hub history (`bdrive log -p <path>`) usually covers the need.
-- **Knowledge syncs as a scoped folder.** Inside a repo, always `--shared <dir>` — never the repo root. A dedicated knowledge folder (an empty dir, a standalone vault) may be the mount itself. The sync scope is per-device (`.bdrive/` never syncs), so recommend the same `--shared <dir>` when each teammate connects.
