Adversarial review gate for scenario-based BC work; sole emitter of work_done for assign_scenarios and bugfix-with-scenarios dispatches
Routes inbound lead messages to the correct BC subagent after sufficiency gating; the sole entry point for all BC inbox processing
Determines whether an inbound lead message is sufficient to act on, or whether a clarify response is required before dispatch
Merges the work branch into the BC's main and pushes so the work_id commit is reachable from origin/main before any work_done emission
Situational mechanics for the turn-limited PO<->Architect BC-decomposition collaboration. Load this when you are actively running a decomposition exchange with the PO (or, as the PO, with the Architect) and need the round cap, the extension protocol, and the ship-from-here rule. Per PDR-014.
Executes a bd-decomposed implementation plan sub-issue by sub-issue with context isolation and mandatory TDD per behavior
Use when implementing any assigned scenario or bugfix, before writing implementation code
Isolates each dispatch's implementation work in a dedicated git worktree and branch named for the work_id
