Analysis half of the pipeline in docs/roto-puppet.md. Stabilises a face out of a clip via a similarity fit on rigid landmarks, reduces the lip contour to a fixed vertex budget, selects sparse keys on velocity minima, and previews the result as flat indexed fills so timing can be judged without an Animator Pro render. - landmarks.js ordered lip/oval rings; slot position is vertex identity - mathutil.js closed-form 2D similarity, Procrustes mean, transform smoothing - pipeline.js stabilise -> subsample -> key-select - raster.js indexed scanline fill, no antialiasing - take.js take-file writer - selftest.js 29 assertions, incl. ring simplicity at every vertex budget Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
