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.

Finish the migration: all 65 scenes on the identity artifacts
Two helpers made the bulk of it mechanical. `inkStroke` is a drop-in for
sigEdge — the same line at the identity's weight rather than the track's — and
`castForm` is a drop-in for sigForm, same signature so call sites do not change
shape. With those in place the substitution table is one-to-one:
sigForm( -> castForm( sigShape( -> castMain( sigEdge( -> inkStroke(
Forty-seven scenes went through that pass in one run: twenty-six take the cast
and the ink, twenty-one take the ink alone. Then the gate ran over all sixty-five
and found three the pass had broken, which is the entire reason it exists.
Spectrum Sculpture rendered pure black. It had been using sigShape as a RADIAL
METRIC rather than drawing it, and the cast carries notches and a hollow — an
annulus used as a radius turns a sculpture inside out. Reverted to sigShape and
dropped to ink only. The lesson generalises: a scene that reads a form as
geometry is not a scene that draws it, and the classifier cannot tell those
apart from the source.
Eclipse Field stopped honouring its `style` trait. It opts out of surface grain,
so sigEdge was its only style evidence, and the ink replaced it. The trait claim
is now dropped — and so is the lint change that had let inkMask count as style
evidence, which was wrong and was hiding exactly this. A trait is a property of
the track a scene may honour; an artifact is content it draws. Taking the ink
says nothing about whether a scene responds to u_sigLine.
Circuit Bloom went empty at the bottom of its `grown` range, where the pads were
carried by a hairline and the ink's stroke is thinner than the edge it replaced.
Now filled as well as stroked.
Also: the backtick check now covers every shader literal rather than only the
preamble, because a mechanical pass over sixty files reintroduced one
immediately. Three rounds lost to that typo is enough.

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.
