What each task in a plan is handed, and what it is not

A plan runs several coding-agent sessions, one after another or several at once. None of them shares memory with the others. Each one starts with an empty context window, so the only thing that carries knowledge forward is what the orchestrator decides to hand over. That decision is worth reading, because it is the difference between a task that continues the work and a task that rediscovers it. Disclosure: I build Ordewell, so what follows is how it does this rather than a survey.
