**`declareVariable`'s field is `declaration`, not `decl`.** Documented wrong in three places across two SDK reference pages. This one fails *silently* — the handler reads `op.declaration`, gets undefined, and returns EMPTY at sdk/src/engine/mutate.ts:991. No throw, no patch, no error. A reader copies the example and nothing happens. types.mdx opens by claiming it was verified against types.ts, which is where the correct name is (line 134). **Colour grading says eighteen presets; the Grade panel has thirteen.** Eighteen is the combined total. The other five carry effects and live in the Effects panel — colorGrading.ts derives GRADE_PRESETS by filtering EFFECT_PRESETS out, and colorGrading.test.ts:25 asserts VHS Playback is *not* in Grade. I wrote that sentence today and used VHS Playback as the example, so the page sent a reader to Grade looking for something that is not there. The visual brief further down had the same error baked in; fixed before anyone shoots it. **`hyperframes render` on a slideshow does not fail — it lies.** The page said export "is not currently supported", which reads like the command errors. The skill is emphatic: a deck has no master root composition, so render resolves only the first slide and writes a silently truncated MP4 — six seconds of a forty-second deck, no warning. That is now a Warning saying exactly that. I also swept every documented edit-operation field against sdk/src/types.ts. Six looked wrong and five were my regex not stripping the `?` optional marker; `easeEach` and `resolvedSelector` are real, at types.ts:178-179. One genuine error out of that sweep, the one above.
