Summary by cubic
On OpenCode 2, Claude models the plugin supports but OpenCode's own catalogue doesn't yet list (e.g. Claude Fable 5.2) now appear in the model picker, matching OpenCode 1.
Adds a provider transform that inserts missing catalogue rows with limits, prices, and adaptive-effort variants, while preserving exact host rows and leaving other providers untouched. Request routing and credentials are unchanged.
