Region lock: a keyframe pin can cover part of a frame. Transparent areas of an
i2v anchor are dropped from the packed sequence entirely — not blanked, not
noised, absent — so the model invents them. Row deletion re-derives the layout
from upstream's own output; two patches share one keep-mask so they cannot
disagree. Surfaced through the anchor's alpha, which needs no new wire and works
in the Editor. Excluded pixels are filled with the kept area's mean before the
VAE so no hard edge bleeds in. EXPERIMENTAL: fl2va saw whole condition frames.
Taste bias: the liked direction Studio already learns is now also added AFTER
H3's token refiner, where it lands as sent instead of being mixed across tokens
and normalized away. Relative to the span's own row norm, so one strength means
the same thing on every prompt. How far to push is a fifth learned gain,
centred on 0 and signed; h3_taste_bias is the manual override. Needs 3 liked
runs.
Gain state generalized to per-key centres, bounds and exploration width.
Tests: 1608 passed (+46). Untested on a rental.
