Release Notes

Added

  • (step-naming,mcp) drop ambiguous nesting-root aliases and close the worker stats gap
  • (serve,worker) stale-run sweeper, agent_block declared model, engine max_hold_ms config
  • (operator) run-scoped operator pin — launch binds the spawn route to a session
  • (bp_dsl) fanout stages in B.pipeline

  • (worker) opt-in structured JSON submit via submit_format meta

Fixed
