Under AWS pressure, avoid `class=beast` unless the task really needs 48xlarge-class CPU. A `beast` request starts at 192 vCPUs and is the easiest way to trip regional EC2 Spot or On-Demand Standard quota. The repo-owned `.crabbox.yaml` defaults to `standard` and multiple capacity regions. Use `fast` for heavier broad checks, `large` only after standard/fast are not enough, and `beast` only for exceptional CPU-bound lanes such as full-suite or all-plugin Docker matrices, explicit release/blocker validation, or high-core performance profiling. Do not use `beast` for `pnpm check:changed`, focused tests, docs-only work, ordinary lint/typecheck, small E2E repros, or Blacksmith outage triage. Use `--market on-demand` for capacity diagnosis so Spot market churn is not mixed into the signal.

Under AWS pressure, avoid `class=beast` unless the task really needs 48xlarge-class CPU. A `beast` request starts at 192 vCPUs and is the easiest way to trip regional EC2 Spot or On-Demand Standard quota. The repo-owned `.crabbox.yaml` defaults to `standard`, multiple capacity regions, and `capacity.hints: true` so brokered AWS leases print selected region/market, quota pressure, Spot fallback, and high-pressure class warnings. Use `fast` for heavier broad checks, `large` only after standard/fast are not enough, and `beast` only for exceptional CPU-bound lanes such as full-suite or all-plugin Docker matrices, explicit release/blocker validation, or high-core performance profiling.

`.crabbox.yaml` owns provider, sync, and GitHub Actions hydration defaults for owned-cloud lanes. It excludes local `.git` so the hydrated Actions checkout keeps its own remote Git metadata instead of syncing maintainer-local remotes and object stores, and it excludes local runtime/build artifacts that should never be transferred. `.github/workflows/crabbox-hydrate.yml` owns checkout, Node/pnpm setup, `origin/main` fetch, and the non-secret environment handoff for owned-cloud `crabbox run --id <cbx_id>` commands.
