Crabbox

Use the Crabbox wrapper when the task needs remote proof for broad tests, CI-parity checks, secrets, hosted services, Docker/E2E/package lanes, warmed reusable boxes, sync timing, logs/results, cache inspection, or lease cleanup.

Crabbox (https://crabbox.sh) is the transport/orchestration surface. The actual backend can be:

• brokered cloud Crabbox: direct provider (e.g. provider=azure or provider=aws), lease ids like cbx_..., syncDelegated=false
• Blacksmith Testbox through Crabbox: delegated provider, provider=blacksmith-testbox, ids like tbx_..., syncDelegated=true

Do not describe delegated runs as direct-provider runs; report them as Testbox-through-Crabbox with the tbx_... id and the Actions run link.
