# `ExSandbox.Conformance.CapabilityUnavailable`
[🔗](https://github.com/FoundryStack/ex_sandbox/blob/v1.2.0/lib/ex_sandbox/conformance/capability_unavailable.ex#L1)

The suite's third outcome (012 T034).

Raised when a check needs a host capability that `ExSandbox.Capability` reports
absent, or when a resource cap could not be demonstrated either way
(`FR-012b`).

It is an exception so it terminates the check, but it is **not a failure** —
the group wrappers translate it into an `ExUnit` skip carrying the reason. The
distinction is `FR-011`'s: an exclusion is something a consumer asks for, and
nothing here is reachable from consumer configuration.
