Package adapterkit holds the helpers every first-party adapter needs but no vendor SDK touches: schema rendering, the terminal-error rule, and the FilePart exactly-one guard.

Package jsonclose closes truncated JSON documents: the state machine both the OutputDecoder's prefix salvage (partial_json.go) and mw.RepairJSON need.

Package jsonconflict holds a fixture type for schema tests that need an embedded field to collide with a struct's own JSON name.
