// Map phase for the archestra-dev-bench-analysis skill.
// One Sonnet triage agent per rollout, fanned out by the Workflow runtime
// (auto-batched at the concurrency cap — no manual 8-at-a-time loop). Each
// agent reads its own trajectory.md and WRITES its judgment — a single JSON
// object (rubric grades, reward-hacking flag, observations) — to a file, so
// the 78 triages never flow back through the orchestrator's context.
// bin/render-triage.mjs validates/renders those files afterwards.
//
// args (passed verbatim by the caller — small scalars only; bulk stays on disk):
//   {
//     triageDir:   absolute dir the agents write <NN>.json into (must already exist)
//     promptsDir:  absolute dir holding one pre-rendered triage prompt per rollout
//                  as <NN>.txt (prepare.sh fills the MAP template placeholders)
//     rollouts:    manifest order, [{ idx, id }] — id is used only for the display label
//   }
// returns { written, total } — counts only; the doc is assembled by the caller from triageDir.
