• catalog_render_matrix Render one preview across the cross-product of the given override axes in a single call, returning a hash/size observation per cell (observe=png adds the pixels
• catalog_list_devices List the `@Preview(device = ...)` ids this server's render lane recognises, with each one's dp size and density. The `device` override takes one of these ids; a

• catalog_history_list The render timeline for one preview: which versions of its rendered bytes exist, when each appeared, and whether the preview is unstable (re-renders differently
• catalog_history_diff Compare two of a preview's recorded renders. Defaults to the two newest — did the last publish move this preview? A metadata comparison: the timeline's versions
• catalog_history_read Fetch one historical render's pixels through this server, by `commit` or `blob` (a prefix is enough). Use when an agent cannot reach the delivery branch itself,
• ui_builder_list_catalogs List the component catalogs a UI-builder design can pin to. Start here: a design's `catalogPin` must name a revision this server actually serves, and each catal

• ui_builder_preview_catalog_recovery Dry-run recovery of a design whose stored catalog pin no longer resolves. The server selects the exact currently served pin for the same catalog system and retu

• ui_builder_create_design Create a design, either from a whole `document` you supply or by copying an existing design named by `fromDesignId`. Copying is usually right: a document's `cat
