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.

The hip ends of the gabled house and Oak's lab come out as black teeth
marching down the slope instead of battens running with it.
The depth->row map is authored for columns the drawing paints edge to
edge. A tapered column starts further down the band, and the surface was
clamped into its first DRAWN row to stay inside the silhouette -- but a
column's first drawn row is its silhouette CAP, and the cap is outline
black. On a tapered column the map spends most of the roof's depth above
that cap (seven of the gabled house's fifty depth voxels land on it
outright), so the clamp painted one outline pixel the length of the
slope and roofCycle beat against it: black punctuated by the real batten
colour every 4 rows on the house, every 8 on the lab.
Lift to the column's first PAINTED row instead -- the same refusal to
let outline black stand as a face that measure() already makes for the
side faces, which the roof band was never given.
Geometry is untouched: voxel, shell and recess counts are identical for
all 50 templates. verify_roof now asserts no roof surface samples its
column's cap, and tests/roof_cap_shots.lua shoots the two Pallet Town
drawings A/B.
The version bump and CHANGELOG entry are left out deliberately, so this
does not collide with the release flow.
