Four things, all found by shooting the feature rather than by reading it.
The flat-pic tint was a no-op for the five colour-table species. tintFor ran
synthetic reference colours through the lookup, none of them were IN it, so
every ratio came back 1 and the tint was discarded -- a shiny Gyarados drew
an ordinary blue pic. Those species now measure the tint from the table's own
entries.
It was also a no-op for most SLIDE species, for a better-hidden reason: a hue
rotation moves red toward cyan and cyan toward red, so averaged over a
balanced set of references the ratios cancel and every species reports no
tint. Charizard and Ponyta both came back neutral. The tint is now measured
against the colour each species is actually MADE of -- a modal body colour,
generated into data/shiny_colors.lua as `dom`. 132 of 151 now carry a usable
tint; the rest genuinely shift too little for one to mean anything.
The sparkle drew sixty quads a frame that nobody could see. It was built to
numbers a tenth of the scale of a mon card -- a ring seven units across,
inside a Gyarados -- and additive drawing keeps the depth test, so all of it
was rejected. Sized against the card now, and pulled toward the camera the
way the move-animation card is.
And the summary PIC cannot be recoloured by touching pixels: the art is
four-shade DMG grey and the colour is applied afterwards by the palette pass.
That attempt is reverted, with the reason left where the next person will
look for it. The star is the designation that works there.
Also: tools/shiny_colors.py now resolves its own paths instead of hardcoding
a worktree, and the extract test gained a hard failure when NOTHING
recolours -- which is what a missing colour table looks like from the
outside, and it passed through it once already.
Evidence in .claude/shiny_update, every case beside its own control.
Gen 1 has no shininess of its own, but it has the four DVs Gen 2 reads to
decide it -- and the engine already ships that reading (Stats.isShiny, its
own comment calling it "the RBY virtual shiny", allowlisted for mods
precisely so an indicator mod can call it). Nothing new is stored on a
Pokemon and nothing migrates: every save already contains the answer, and
this starts drawing it. Random DVs land on the pattern 1 in 8192, which is
the classic rate and the default the odds dial ships at.
Deriving rather than storing is what makes it survive a save, a box, a
trade and an evolution with no second copy of the truth to drift. mon.shiny
is a cache written from the DVs, never read as the source.
The roll goes in Pokemon.new -- every wild, gift, starter and traded mon is
built there, and it is before the battle bakes its sprite, which
battle.started is already too late for. It draws from the mod's own random
stream so installing this does not shift the sequence damage rolls and
encounter slots come out of. Trainers stay ordinary by themselves: the
engine pins their DVs, as the real games do.
The models are genuinely recoloured, as part of the extraction. Each
species is decoded once, packed as usual, then recoloured and packed again
as NNNs.dsm. The colours are Stadium's own HSL slide (hue in degrees,
saturation and lightness on a -8..+8 scale at 12.5% a step); five species
carry an explicit colour table instead, because Stadium gives them a real
alternate texture that no single slide reproduces -- Jigglypuff's body must
stay pink while its irises rotate to green.
Extraction is the right moment because StadiumFx's generated frames are
still marked there and the packer drops the marker: it is the last point a
flame is distinguishable from a hide. A shiny Charizard has a shiny hide
and an ordinary fire. The normal packs are written BEFORE the recolour, so
they come out byte-identical and stadium_extract_test still diffs all 151
against the Python oracle unchanged -- no format change, no DSM4, no second
implementation to keep in step. REV goes to 3 so an existing cache rebuilds.
Flat art is tinted instead, because the engine bakes a species palette into
a cache with no notion of which individual is drawn. The tint comes from
that species' own slide rather than a generic gold. A multiply can only
darken, so species whose shiny is lighter read quieter there than on the
model; the status page's star is the mode-proof mark.
Tests: 58 assertions in tests/shiny_test.lua, including the colour
transform against 640 real colour pairs lifted from the verified texture
set, the DV model, the read side, and the end-to-end through the engine's
own constructor. stadium_extract_test gains --mod (worktrees have neither
the ROM nor the packs, both gitignored) and now also checks that every
shiny pack is the same length as its twin and actually differs.
