Two live cdb captures on the paired 2013 client at the Holtburg doorway:
the blockset template (every Render::block_check call of one frame — 2,601
resident blocks x 2 exit views) proves retail tests a9c9 at ring slot
25,46 and returns PARTIALLY then OUTSIDE; the blockcheck template dumps
its four corner interval vectors (0 0 0 0 300.4|310.2 and 0 0 0 1001 ...,
slab 75..330). acdream's replay at the same P pose reproduces the sentinel
pattern, the four edge planes and both verdicts, drawing a9c9 once, with
clip heights 298.8/308.5 m — a 0.5 % plane difference (about 0.35 px of
projected door-vertex position). At the fixture pose that margin is what
flips the south-west corner from inside to outside on the fourth edge
plane, so retail's four-corner unanimity test says OUTSIDE where ours
says PartiallyInside. Not fixable bit-exactly short of D3D's x87
transform; the KnownFailure row stays with its comment rewritten, the
register carries AD-118, and the first filtered capture's silent miss
(cdb sign-extends poi() inside .if; use dwo()) is noted in the template.
