  "goal": "Determine what it would take to add a 'pi' runner adapter to mempalace's `task launch`, which today supports only codex and claude. Read the adapter contract from the installed source and report the concrete interface a 'pi' adapter must satisfy, what pi can already provide, and what is missing or awkward.",
  "deliverable": "1) The adapter contract, stated as the exact tuple/callable shape _TASK_RUNNER_ADAPTERS maps to, with file:line for each element. 2) Every call site that consumes an adapter, with file:line and what it expects. 3) A per-requirement table: requirement -> which pi flag/output field satisfies it -> or GAP if nothing does. 4) An honest LOC estimate for a 'pi' adapter, with the reasoning. 5) The single biggest risk of doing it. Do NOT write any code.",
