Expand description
HostError — the one typed error the host runtime raises
(SPEC.md §10 “fail loud”). Everything a fan-out or a single
provider exchange can go wrong with is a named variant here; nothing in
the hot path panics. contextgraph-host owns its own error type rather than
borrowing stella’s so the crate stays industry-facing and dependency-
light (SPEC.md §1 — depends only on contextgraph-types + transport
crates).

- Host
Error - Anything the host runtime can surface while talking to a provider.
