Ln 300 Task Coordinator

This coordinator takes a Story, builds an ideal 1-8 task plan from acceptance criteria without looking at existing tasks first, then scores readiness and routes to create, add, or replan workers. It runs a seven-phase pipeline with graph and research MCP integration for symbol lookup and hypothesis verification. The decomposition uses a four-layer model (Foundation, Invocation, Knowledge, Wiring) and writes an AC-to-scenario traceability table before scoring. If the readiness score sits at 4-5 or coverage looks ambiguous, it can optionally call an external advisor agent to validate task boundaries. You'd use this when a Story needs task breakdown and you want the planning logic separated from the mutation step.
