Dry-run a full Composition object against the SAME pure, DB-free authoring guards saveComposition enforces, WITHOUT persisting it (no project needed). Checks: wire shape (Zod), primitive membership (unknown_primitive / custom_missing_sourcecode), required-param shape (invalid_primitive_params), clip↔track family (clip_source_track_mismatch), and reframe coverage (reframe_coverage_gap). Always returns ONE shape — 200 { valid, errors, quote } — for BOTH malformed wire shapes and deep-invariant failures (so branch on `valid`, not on HTTP status); errors[] lists every problem at once as a sanitized envelope { code, stage, category, retryable, message, fix } you can fix before composing/rendering. The `quote` triple states the render price to finish from a valid composition — relay it to your human BEFORE create_render. `valid:true` means save-safe EXCEPT for the three genuinely DB-bound checks that can only run at save/render, because this tool takes no project: trim-bounds (needs the media duration), image/asset-on-a-video-track (needs the media kind), and componentId resolution (needs the installed components of YOUR org — a `{kind:'component', componentId, props}` clip naming a component you have not created, or naming a CATALOG PRIMITIVE, passes here and is refused at save with `component_source_unavailable`). Pass the Composition as `body`.
