Adds the deterministic eval primitives the skill calls into: scripts/render_diff.sh SSIM diff between two MP4s, JSON summary, configurable threshold scripts/frame_strip.sh side-by-side comparison strip for visual debugging scripts/lint_source.py pre-translation lint over Remotion source — blocks/warnings/infos The harness is decoupled from the render pipeline: it accepts paths to already-rendered MP4s. The skill orchestrator (PR 7) drives both renders and feeds the outputs in. This keeps the harness usable in CI, in sandboxes, and on any machine that has ffmpeg without needing the full Remotion + HyperFrames toolchain. Lint catches the patterns from the skill's out-of-scope list: - useState / useReducer (state-machine driven animation) - useEffect with deps (side effects) - async calculateMetadata (Promise-returning composition metadata) - @remotion/lambda imports - third-party React UI libraries (MUI, Chakra, Mantine, antd, shadcn, Radix, NextUI) - delayRender / useCallback / useMemo (warnings) - staticFile / interpolateColors (info — translatable but flagged) Smoke test (scripts/tests/smoke.sh) exercises all three scripts against synthetic inputs: identical ffmpeg testsrc videos pass at threshold 0.99, different ffmpeg testsrc videos fail at 0.99, frame_strip produces a strip.png, lint produces 0 blockers on a clean fixture and >=3 blockers on a fixture that uses useState + useEffect + MUI + async metadata. Validated locally: smoke.sh exits 0.
