Task board lives in [INDEX.md](INDEX.md) — one row per task, one file per task (`<id>-<slug>.md`), agent-harness format. That file is the source of truth for execution order; this README is a human overview only.
Everything cluster/backend/infra (GitOps, DNS, RBAC, the real `atlas` Go service, rate-limiting tiers 1-3, observability) is out of scope for this repo — see [REQUIREMENTS.md](REQUIREMENTS.md), a handoff spec for whoever builds that separately.
