Two projects, one teamctl, with bridges

A pattern for running unrelated teams under a single teamctl instance. Projects are isolated by default — nothing in product can reach blog without an explicit bridge. When the two managers need to talk about a specific topic for a bounded time, you open a bridge:

teamctl bridge open \
  --from product:manager \
  --to   blog:editor \
  --topic "share launch event photos" \
  --ttl 120

teamctl bridge list      # see open / expired / closed bridges
teamctl bridge log 1     # replay the transcript of bridge #1
teamctl bridge close 1

While the bridge is open, only the two named managers can DM across. Every message exchanged is recorded with thread_id = bridge:<id> for audit. The pattern shows up in examples/newsletter-office/ (newsroom ↔ blog handoff) and examples/oss-maintainer/ carries the same HITL spirit at single-project scope (release_manager gates release-critical actions via plan-mode). The compose file below stays preserved as a reference recipe.

See concepts/bridges/ for how bridges integrate with HITL — every bridge open / close is auditable, and the --ttl is a hard timeout (no implicit re-opening).
