Ledger Orchestration (Magentic-One)(LO)

An orchestrator drives a team of specialized agents using two ledgers: a task ledger holding facts, educated guesses, and a plan, and a progress ledger where the orchestrator self-reflects each step on whether progress is being made, whether the team is stalled, and which agent should act next. When progress stalls, an outer loop updates the facts and revises the plan. Introduced in Microsoft Magentic-One.
