Campaign S slice S4, the half that landed. Retail's CTransition::
adjust_offset @0x0050a370 branches on dot(offset, contactPlane.N) at
0x0050a4fa: moving INTO the plane subtracts the normal component
(0x0050a529), moving AWAY calls Plane::snap_to_plane @0x00509c50 —
which preserves X and Y and re-solves ONLY Z so the offset lies in the
plane (the d terms cancel algebraically), no-op under the
0.000199999995f |N.z| epsilon. acdream ran the orthogonal projection in
BOTH directions, shrinking downhill XY travel by cos^2(theta): 25% at
30 degrees, 50% at 45 — AD-65's recorded shortfall, now retired.
The combined Opus review independently re-derived the algebra, the
branch polarity, the epsilon's bit-identity (17b75139), and the
sabotage magnitude (the re-instated projection yields X = 0.75 =
cos^2 30 exactly), and verified the delta is 4 non-comment lines with
the into-plane arm, the crease arm, and both no-plane arms untouched.
Its blast-radius sweep found the away arm exercised but NOT
discriminated by any pre-existing test — every one asserts lower
bounds the snap over-satisfies — so the two new exact-value tests are
the only discriminating coverage, recorded in the test's class doc,
and the felt 33-100% downhill speed-up is the morning gate's one row.
AD-66 (the push-out's bare radius) is WITHHELD: byte-confirmed twice,
implemented, then pulled after the same clean-room binaries measured
contradictory absorbed-tick outcomes flipping with nothing but test
assert shape — issue #341 carries the observation matrix and the
apparatus plan; its two exact-value tests are [Skip]-ed; the retained
substitution's rationale is restored at the site per review F1, with
the review's remaining findings (F2/F3/F4/F5/F6) applied and F8 filed
as #342. AD-69 filed: the same block omits retail's get_block_offset
seam-frame correction, deferred to the AD-66 relanding for
attributability. #340 filed: a fifth load-sensitive flake.
Review verdict: PASS. AD-65 is provably unable to reach the #341
anomaly's code path (the absorb scenario takes the crease arm).
Clean-room suite: 11,239 passed / 6 skipped / 0 failed.
