Use when you have a multi-ticket epic (many related tickets across repos) and want to work as many as possible in parallel without breaking dependencies, or need to know what is unblocked now — ingest the epic and its child tickets, build the dependency graph from both formal links and free-text "Dependencies" notes, compute a parallel wave schedule, then act as a persistent coordinator that spawns a session per workable ticket and re-verifies what unblocked as tickets finish.
