Scaffolds frontend/ (shadow-cljs, reagent 1.2.0, re-frame 1.4.3) and ports everything below the data model, with the JS kept as a numeric oracle. domain/landmarks index tables, verbatim domain/ring subsample, offset, simplicity domain/geom similarity fit, procrustes, moving average domain/raster indexed scanline fill, stencil, disc, rect domain/palette the ramp, and the no-sampled-RGB rule 58 tests, 166 assertions. Parity with js/ on the identical 72-frame synthetic track: fit-similarity, procrustes-mean, fit-residual, moving-average, smooth-transforms, offset-ring and subsample-slots to 1e-9; the raster pixel-for-pixel over the whole buffer. Three deviations from the JS, each for a reason: - synth.cljs jitters from a SEEDED generator, not Math.random. Parity is only checkable if both sides can be handed the same track, and a failing assertion has to be reproducible. `:rand-fn` takes the generator over, so oracle.mjs stubs js/Math.random and js/ itself stays untouched. - raster/->rgba replaces toImageData. ImageData is a DOM type and domain/ may not touch the DOM; returning plain bytes also lets the no-intermediate-colours assertion run in node. ui/canvas wraps it later. - offset-ring lives in domain/ring, not domain/geom, per architecture.md: it is an operation on an ordered traversal, not on a transform. Step 1's "done" also names the swapped-iris vote, but pairIrises is in pipeline.js and belongs to step 7. The precondition is asserted instead -- `:swap-iris` really does move both blocks -- so the vote will have a track that disagrees with it when it arrives. One finding, recorded in full in the test that measures it: smooth-transforms buys nothing on the synthetic track. Against jitter-free ground truth, radius 1 helps by 17% on one noise realisation and hurts by 0.5% on another, so its benefit is within noise; from radius 2 up the cost is unambiguous, and by radius 5 the filter is below the true motion's own high-frequency energy, i.e. smoothing away performance. The test pins the shape of the knob rather than a preferred value. This may say more about the synth's jitter being unrealistically small (+/-0.001 normalised) than about the knob; step 6 settles it on real footage.
