## Summary Mock `node:child_process.spawn` to surface `ENOENT` and verify ffprobe's three callers behave correctly when ffprobe is missing. ## Why `Chunk 9B` of `plans/hdr-followups.md`. The PNG cICP fallback in `extractMediaMetadata` was added to support environments without ffprobe, but no test pinned the behavior — silently regressing it would break HDR image support on any system without ffprobe installed. ## What changed `packages/engine/src/utils/ffprobe.test.ts`: mocks `child_process.spawn` to surface `ENOENT` and asserts: - `extractMediaMetadata` falls back to PNG cICP metadata for image inputs. - `extractMediaMetadata` rethrows for non-image inputs lacking a still-image fallback. - `extractAudioMetadata` + `analyzeKeyframeIntervals` propagate the install-hint error verbatim. ## Test plan - [x] All new tests pass. - [x] No production code changes — pure regression coverage of existing fallback behavior. ## Stack Chunk 9B of `plans/hdr-followups.md`. Test-only change, independent of all other chunks.
