A business package imported the Remote assembly for `ctx.remote` and the
Connection plugin for the wire types it passes around. The assembly now
re-exports the carrier's Client-facing types, so a business package names one
package. The re-export is type-only: the carrier's runtime values keep their
own module edge, since inlining them here would duplicate the carrier inside
the assembly bundle.
Four surfaces that had no Remote assembly dependency declare one now.
Adapter schemas now carry only credential references, but the Models join, onboarding readiness, shipped overlays, SDK scaffolding, fixtures, and active decision prose still treated a redacted literal apiKey as a supported compatibility state. That residue made an unsupported field look contractual and pinned Schemastery silent-dropping as behavior.
Delete those branches and examples, and let compositions and scaffolds use adapter-owned reference and environment resolution. Do not add a tombstone validator or change generic unknown-key behavior: literal adapter credentials have no migration contract to preserve.
