The Sledding constant has been the byte-confirmed cos(10 deg) =
0.98480775f in production since 252e8068 (2026-07-30), which also struck
the register row. Five hours later a8a7d64b — reverting the UNRELATED
TS-4 commit 5e2be19b — restored this file's older hunk and resurrected
the un-struck row text while leaving the code fixed. The zombie row then
cost tonight's session a full duplicate byte-derivation: the stale row
said 0.99999536f was live, so the binary was re-read to prove what
252e8068's own commit message already contained verbatim.
Tonight's derivation note is corrected to what it actually is — an
independent confirmation of the week-old fix — and S5 collapses to this
bookkeeping: no code change, no feel gate owed; the user has been
playing on the fixed constant for a week.
Process rule filed to memory (feedback_register_revert_resurrection):
after any revert whose diff touches the register, re-verify EVERY row in
the touched hunks; and before acting on a row's 'our code does X' claim,
grep the cited file for the claimed expression first. AD section
51 -> 50 active rows.

Campaign S S1A, both outcomes the measure-first rule exists for.
AP-157's CylHeight half is RETIRED as a non-divergence: retail's own
cylsphere overload (CObjCell::find_cell_list @0x0052b9f0) copies
localtoglobal(low_pt) + radius per cylsphere, capped at 10, and never
reads height — retail collapses a cylsphere to a base-point sphere
exactly as acdream does.
The sorting-sphere half measured REAL against retail's registration set
— 1,812 of 3,343 evaluated Setups (54%) fail containment at 1 mm, worst
shortfall 18.135 m — and then PROVEN collision-unreachable: for this
branch the flood spheres and the collision-test geometry are the same
per-part Sphere list, so every omitted cell is one the entity's test
geometry cannot reach, and retail's wider sorting-sphere registrations
are narrow-phase rejects on retail too. Fix deferred to the next
bake-schema revision rather than performing Slice I3 surgery for zero
behavioural delta. The measurement test stays in the tree as the
permanent record (population cross-checked against the dispatch test's
independently-committed constants: 3,506 = 3,605 - 99).
AD-55 is byte-decoded and RESOLVED against our constant: the binary
loads qword [0x007c6b28] = pi/18 exactly and executes FCOS — retail's
Sledding flatness threshold is cos(10 deg) = 0.984808. Our 0.99999536f
is cos(0.17453 DEGREES): the radian literal misread as degrees, which
makes the object-friction arm unreachable on real terrain (nothing is
flatter than 0.175 deg). Evidence note carries the full instruction
listing and the polarity of the test ah,0x41 / jp idiom; the one-line
fix + conformance test is S5, queued behind the running implementation
slice for build-slot reasons.
