adapter_build
Diagnostic `nanook::cli::adapter_build`
Summary
failed to build adapter `{0}`
Details
When this fires
This is the CLI-side wrapper for an adapter build failure. It pops up during nanook check and at nanook run startup when AdapterRegistry::validate rejects an [[adapters]] entry, usually because of a missing or malformed opt. The named adapter in the message is the name = "..." field on the offending block.
What to check
Follow the chained inner diagnostic; the span is anchored on the offending TOML literal. Otherwise inspect the [[adapters]] block for that name.
