Take the effects off the visualizers and leave them to the grade
Forty-nine scenes carried their own `glow`, every one of the sixty-five added its own grain, and a handful had bloom, chroma, haze, smear or trail besides — all of which the post chain already does, with an envelope and a threshold no scene can see. Two uncoordinated effect layers is the smaller half of the problem. The larger half is that an effect knob sampled per song makes a scene look varied across parameter draws while its structure never moves, so the gallery and the variety harness were both being told a scene was original when only its halo had changed. Removed in three shapes. Scene grain goes entirely — the post chain owns it. Statements that ADD a falloff term scaled by the effect are bloom by another name and are deleted. What remains is an intensity on something already drawn, so the uniform is pinned to its default and the knob deleted: the picture survives, the fake variety does not. Reactive entries driving those params went too, since an effect modulated by the audio was the most convincing fake of the lot. That broke the style trait, which is the interesting part. Surface treatment had been leaving the scenes for two commits — sigGrain to post, sigEdge to inkStroke — and removing the last of it left `style` with almost nothing to express: a style+shape signature had two eligible scenes in the whole library. The trait is not obsolete, it has moved, so inkStroke and inkMask now read u_sigLine and u_sigSoft alongside the ink's own weight and edge. A scene drawing in the song's hand honours the track's line weight by construction, and the runtime probe confirms it rather than taking it on trust. This reverses a call made two commits ago for a reason that only became true now. One check needed re-aiming rather than fixing. Two independently built shows are two WebGL contexts, and engine/hash.js says at the top that bit-exactness is a same-context guarantee; the check had been demanding it anyway and getting away with it because the scenes it happened to cast were bit-stable. A casting change put smooth-gradient scenes in frame and the last bit moved. Measured before touching the check: three levels out of 255 across 2.6% of pixels, invisible. The cross-context comparison is now a distance with a ceiling of four, and bit-exactness within one show is still demanded by the check below it. 89/89 checks, 11/11 tests, all static gates.

A reproducible migration, and the first eighteen scenes through it
The library is sixty-one scenes, which is too many to convert from memory or from taste, so the migration is a queue with a gate rather than a judgement call per file. Three pieces. A classifier reads each shader and assigns a tier from evidence in the source — drawn, figure, field, treatment — so two passes over the library reach the same answer and the work has an order. MIGRATION.md is the recipe per tier, written to be followed mechanically. And a gate makes the result verifiable: `consumes` is now a schema field, the lint enforces it in both directions, and the per-scene battery renders each scene under two deliberately distant identities and requires the picture to change. That gate is the part that matters. Without it `consumes` is a comment, and the whole inversion becomes unverifiable at exactly the point where it stops being checkable by eye. With it, a scene that declares the cast and ignores it fails. Eighteen scenes migrated. Four by hand at the drawn tier — Firefly Drift, Metaballs, Floating Geometry, Prism Bloom — and ten at the field tier by script, which is one declaration and one wrapped return. All eighteen pass. The field tier is honestly marginal and the gate says so: every one of the ten moves by 37 to 39 of 255, against 173 to 255 for the drawn tier, and the uniformity across ten unrelated scenes is the tell. That is one global posterisation applying, not ten scenes expressing anything. Cheap, real, shallow. The decomposition moved from identity being worth 54% of the container to 158%, but the stage set changed underneath the measurement and part of that is Metaballs expressing a cast better than Constellation did. What survives the caveat is the useful finding: a migrated library scene carries the identity better than a stage written from scratch to carry it. The four bespoke stages were the wrong shape of effort. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

Three glitch scenes: a press, a loop and a tape
Halftone Misprint is a printing fault rather than an electronic one — the image is never damaged, only separated and reassembled out of register, and nothing else in the library is made of dots. Droste Feedback scales the previous frame where Time Smear translates it, so the image never clears. Analog Wow is the continuous, wet counterpart to Scan Tear and Block Mosh: the error varies smoothly down the frame because every line was written at a different moment. Three things that had to be got right. The halftone ruling is a count of dots across the frame, not a pixel pitch, or a 4K export is the same dot on a bigger sheet. The Droste loop has to CONTRACT — expanding pushes every copy off the edge and leaves a plume instead of a corridor. And all three expressed style only through grain at first, which is the Side Quest 1 complaint: they now put the track's line weight and edge softness into the dot, the ring and the band boundary, taking the measured style response from 24/11/18 to 86/255/88. Neither feedback scene declares a slow axis, with the numbers recorded in the files: their own history moves the ten-second average further than any parameter does.
