Retail's OBJECTINFO::validate_walkable @0x0050d010 initializes its
return slot to OK (0x0050d025) and assigns ADJUSTED only inside the
below-plane guard, immediately after the push executes (0x0050d249).
The guard-fail path — grounded, OnWalkable, plane too steep — jumps
past the contact write, the push, and the assignment (0x0050d1b9 ->
0x0050d251): retail deliberately IGNORES the steep plane at primary
validation so the insert proceeds, the step-down phase fails on the
steep landing, and the edge family produces the per-tick lateral
glide. ACE flattened this into an unconditional return Adjusted
(ObjectInfo.cs:169) and we inherited it; our TransitionalInsert then
retried the byte-identical Adjusted forever — the user's
stop-instead-of-slide.
Evidence chain: the user's retail observation (the axiom), the live
cdb glide profile (edge_slide/cliff_slide 594 each in lockstep,
step_up 0), the D0 implementer's correct STOP (fixtures reproduced
the stuck fingerprint while faithfully executing the ACE-shaped
reading — refuting the reading, not the code), and the capstone
byte-decode both Opus reviewers re-derived independently, including
the stack-slot frame arithmetic and every ret site's eax.
The conformance fixture is the live topology: flat and steep terrain
triangles sharing ONE cell's diagonal (a cell-boundary face does NOT
reproduce the loop — the cell-scoped primary sample never validates a
neighbour's triangle — and is pinned as supplementary). Sabotage:
restoring the unconditional Adjusted reds the discriminator with the
exact stuck position (0.325 m lateral, 28/30 stuck ticks vs 2.602 m /
14/30 fixed; reviewer B's independent five-angle table is monotone
10-85 degrees). Stuck ticks are counted from positions so the
assertion survives the eventual probe strip.
In-game glide gate PASSED 2026-08-08: "Well it works, we are sliding.
I cant detect any speed change from retail."
Filed alongside: #347 + AD-70 (our glide alternates arm/move at half
retail's per-tick rate — retail redirects within the tick; next up by
user direction), AD-71 (the guard's mutable WalkableAllowance operand
vs retail's fixed is_valid_walkable global — now return-value-bearing),
and the reviewers' named residuals in the #345 closure entry
(placement-arm flip, other-cell coverage gap, EdgeSlide-less
projectiles, ACE's server-side shared misport predicting remote
drift-then-snap on steep terrain). The unported IsViewer arm of
validate_walkable is noted in the D0 doc.

The synthetic fixtures reproduce our stuck fingerprint while faithfully
executing the documented control flow; ACE's independent port shows
EdgeSlide reachable only via the OK arm's step-down failure. Together
they force the sharper question: retail's insert returns OK per tick
where ours returns Adjusted. The round-2 cdb script (stack samples on
edge_slide/cliff_slide/step_down + a step_down counter round 1 never
had) carries falsifiable predictions written down BEFORE the capture.

Third attempt, landed on evidence where the first two correctly refused:
the ten-run stability gate passed 10/10 bit-identical (0x42667451, two
clean-room cycles among the runs), the recalibrated golden's every value
measured with derivations rather than guessed, and the historical
measurement flip stands recorded as unexplained-but-unreproducible
after 37 hunt runs plus these 10 found no divergence anywhere.
The mechanism, completing the S4b byte-pin: validate_walkable plants
the sphere at perpendicular r*N.z (byte-faithful, untouched); this push
fires once per settle and lifts to tangent equilibrium dist=r, where
the trigger goes quiet — retail's slope hover, arriving via the push
exactly as the original substitution's own comment predicted retail
had. Sabotage: restoring radius*N.z reddens the discriminating
exact-value test verbatim. AD-65 conformance, the uphill no-flap
guard, and the #331 absorb pin all green untouched.
AD-66 retired (the campaign's last withheld row); AD-69's seam-frame
correction deliberately unbundled, stays active as its own follow-up.
Clean-room suite 11,267 / 4 / 0 — the suite's two AD-66 skips are gone.
User's "port the retail pair" decision is now fully executed; the
hover-look slope gate is the remaining acceptance.

Retail's per-tick edge-family entry (594 lockstep firings, zero
step_up) is the constraint any pseudocode reading must reproduce — the
prior 'retries from scratch, retail-identical' conclusion is refuted by
the live profile, so D0's job is finding the branch that reading
missed, with the step-down-phase-ordering hypothesis named as a
candidate to verify rather than assume. Trap list absolute: the entire
proven-faithful response machinery is off-limits; the fix is routing
fidelity only.

cdb on the PDB-paired retail client during the user's 45-degree glide:
edge_slide/cliff_slide 594 each in lockstep, set_sliding_normal 538,
step_up ZERO. Ours: 18 edge-family firings total, stuck ticks
dead-looping on insert retries. The divergent branch is
transitional_insert's handling of the refused steep walkable — retail
proceeds into the step-down-failed/edge path per tick, we retry from
scratch. The D0 code-reading's 'retries from scratch, retail-identical'
conclusion is corrected by the runtime evidence: the profile is what
the decomp reading could not see.

The user's side-by-side is the axiom: retail glides laterally along the
steep hillside, faster with more approach angle; acdream stops dead.
D0's line-by-line faithfulness of the response path relocates the
divergence upstream — the request shape reaching the transition, the
broadphase question, or state seeding. Next: the cdb live-trace session
at the slope, per the workflow's Step -1.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Five links traced from the named decomp: the below-push never executes
(OnWalkable guard — the probe printed the wrong guard pair), the
from-scratch retry is retail-identical, and validate_transition's
failure path manufactures every captured field including the (0,0,1)
default. Stopping dead may simply BE retail. Two validations remain:
the user observing their RETAIL client at a comparable slope (the
cheapest decisive test there is), and — only if retail visibly
slides — the find_cell_list broadphase question via the cdb toolchain.
The mechanism paragraph's wrong-cause framing is retained and
corrected in place, per the register's own honesty pattern.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The trace shows 275 uniform player stuck ticks: target 0.268m below a
just-too-steep plane (N.z=0.599 vs FloorZ 0.664), below-push Adjusted
on every transition attempt with the IDENTICAL dist each time — the
adjust is recomputed from scratch instead of feeding the next attempt,
attempts exhaust, the tick yields zero. The fix contract's question is
now a single retail cross-read: does transitional_insert feed the
adjusted CheckPos forward, or branch differently on Adjusted-with-
non-walkable. The probe paid for itself in one one-minute run.

Fires only on the stuck-tick predicate (>=1mm XY requested, <=0.1mm
achieved), buffering per-tick phase outcomes cheaply and flushing only
on a stuck tick: per-insert-attempt phase/state/normal/source, step-up
enter/exit verdicts, every ValidateWalkable branch with dist/waterDepth
and both SetCollisionNormal guards evaluated, and the tick's final
AdjustOffset pair. Zero cost when off (flag before any allocation — the
I1 zero-alloc gate stays green), mover id on every line, [ThreadStatic]
buffer per the referee-safety rule. Two tests: fires on a synthetic
wall-stuck tick, silent on ordinary movement.
Diagnostics only; no behavioral change. Suite 11,271 / 6 / 0.

Root cause pinned by IL-decompiling Silk.NET.Windowing.Common:
ViewImplementationBase._inRenderLoop is set at DoRender/DoUpdate entry
and cleared ONLY on normal return, so a throwing frame callback leaves
it armed forever and any later Dispose -> Reset throws "You cannot call
Reset inside of the render loop", exit 82, replacing the original
wounding exception in the report.
The fix mirrors Silk's own bracket exactly: GameWindow._renderLoopArmed
set at OnUpdate/OnRender entry, cleared only on their normal return —
deliberately NOT in a finally, so it tracks the wound the same way
Silk's private field does. ReleaseNativeWindow checks it before
disposing: armed -> best-effort Close() (swallowed so it can never
become the reported failure), no Dispose, and a new terminal status
CompleteWithDeferredNativeRelease with Error kept null — the original
exception stays the primary report. Healthy paths (OnClosing's
in-loop completion, Run()'s tail release) are byte-unchanged, and the
new PublishNativeWindow parameters default to null so every existing
caller and test behaves identically.
Sabotage: disabling the armed-check flipped the deferral test to
Expected CompleteWithDeferredNativeRelease / Actual Complete —
the guard is what the test exercises. Clean-room suite 11,262 / 6 / 1,
the 1 being #340's documented load flake (passed standalone; second
recorded firing noted in its entry).

During a portal transit the two world-frame owners legitimately rebase
on different edges (Runtime at TeleportAdvanced, streaming only after
old-window retirement), and a spawn projection landing in that window
hit the #283 invariant as an unhandled render-path throw — the crash
the user hit entering a dungeon.
The guard's check is unchanged; only the disagreement RESPONSE is
discriminated on the canonical transit authority
(RuntimeWorldTransitState.IsTeleportActive, the same field the App
layer already reads for portal-in-flight): in transit -> the
materializer's existing "not yet" return, parking the projection on
its established retry rides (OnLandblockLoaded's re-attempt loop,
whose ordering guarantees agreement on retry because the recenter
coordinator adopts the new origin BEFORE unblocking new landblock
loads — verified at source; plus OnPosition recovery and
OnAppearance). Outside transit -> still throws: genuine corruption
stays loud. The implementer explicitly ruled out riding the Runtime
placement pump, which would have acknowledged-and-discarded the
completion receipt and silently dropped the entity forever.
Sabotage: removing the discriminator reddened the pre-existing #283
throw tests as well as the new not-in-transit test — the sabotage
defeats the original contract, not merely the new coverage. Four new
tests cover defer, defer-then-agree-then-succeed (projected exactly
once), throw-outside-transit, and the agreeing pass-through.
Clean-room suite: 11,261 passed / 6 skipped / 0 failed. #346 filed for
a sixth, distinct load-sensitive allocation flake observed during the
runs.

The probe design: fires only on the stuck-tick predicate (zero XY yield
against nonzero request), printing per-attempt phase outcomes, step-up/
step-down verdicts, every ValidateWalkable branch with its flag guards
at the SetCollisionNormal site, and the AdjustOffset pair — the
collN=(0,0,1) fingerprint's producer names itself. Trap inventory from
the week's do-not-retry ledger attached so the eventual fix cannot
stumble into a retail-faithful mechanism.

The pre-campaign binary shows the identical 0.0%-yield signature across

The user's report measured two ways: the branch probe shows the steep
face reached only 18 times with a HEALTHY applied cliff-slide (the #32
retention visibly working — lastN is the flat ground, not the face);
the flight recorder shows the actual stop is 838 uniform ticks on
nearly-flat approach terrain eating 100% of angled input with
collisionNormal straight UP and no sliding latch. Not the absorb, not
the slide family. Regression status unknown — the A/B against the
pre-campaign binary is mandated as step 1 before any theory.

Retail floods at authored size regardless of placed scale, which
under-registers ENLARGED objects into neighbouring cells (a
walk-through edge case retail genuinely has). The user chose not to
import that bug for byte-fidelity. Closed; not a cleanup candidate.
This was the campaign's last open decision.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
AP-83/AP-91 claimed no current mover sets PerfectClip. The containment
proof found the opposite and the contract's honest-fallback fired: the
camera probe (the sole production setter) reaches BOTH ACE-derived
tails live — the viewer exemption is creature-only, the shadow-list
walk is unconditional, and static scenery with authored primitives is
a real non-creature population. Every reach is now recorded
(camera-live silently; any non-viewer mover loudly, one-shot), so a
future flag change cannot exercise unreviewed ACE-derived math
silently. Four tests drive the camera's exact call shape both ways;
the sabotage was intelligently adapted — there was no existing cut to
disable, so it flips the one axis the proof depends on (IsCreature)
and asserts reachability inverts. Both register rows rewritten
CONTAINED-not-dormant with severity narrowed to camera-feel (the probe
never commits a PhysicsBody).
Landing note: diagnostics-only diff (two guard calls + counters +
corrected stale comments), verified directly by the session lead
rather than a review cycle — the review budget went where behaviour
changed tonight.
Campaign S CLOSES with this landing: S1A/S1B/S2/S4/S5/S6 done, S3
cancelled, three user-passed gates, one honestly-open item — AD-66's
reland, twice self-refused by its own stability gate, blocked on the
#341 codegen-shape measurement instability whose ABA evidence and
first discriminating experiment are filed.
Clean-room suite: 11,257 passed / 6 skipped / 0 failed.

The reland's ten-run protocol was stable-with-lift, then the
recalibrated form flipped on its first run, and a same-binary ABA
isolated it to assertion CODE SHAPE alone with a hardcoded-constant
control killing the property-read hypothesis. Best remaining story:
JIT inlining/tiering of the settle chain differs by caller IL shape and
some computation in it sits on an exact float boundary deciding WHEN
the one-time lift happens. First discriminating experiment for the
investigation: DOTNET_TieredCompilation=0. The stop clause fired twice;
production is unchanged; no third reland before the boundary is found.

The contract's D0 byte-pin refuted the tangent-placement premise:
validate_walkable @0x0050d010 is planted for every normal mover
(Ghidra + BN + ACE agree; ours is already byte-faithful; only the
camera branch is tangent). With the byte-proven bare-radius push-out
the coherent retail mechanism is plant-then-lift — the push fires once
per settle, raises the body to tangent equilibrium, and both checks go
quiet there. The slope float comes from the push, not the placement,
exactly as the original substitution's own comment argued. The 84%
live fire rate was measured against our push-disabled steady state;
the #341 assert-shape flip now reads as order-dependent settle state.
The user's 'port the retail pair' therefore maps to relanding AD-66's
bare radius alone, with the ten-run stability protocol.
The STOP rule paid for itself: an implementer without it would have
made ValidateWalkable DIVERGE from retail in the name of faithfulness.

The reveal hang (three live occurrences: portal-space, login twice) was
an unhandled OverflowException on the render frame's readiness
evaluation: EnsureRenderDataReady found a packed 64-bit EnvCell geometry
id OWNED but DESCRIPTOR-LESS — the release path removes the descriptor
while render data parks on the LRU, IncrementRefCount restores ownership
on a revisit, and the scheduler's PrepareEnvCellGeomMeshDataAsync has
not yet re-registered — and fell through to the Setup/GfxObj arm, whose
checked((uint)id) cast threw. After that the reveal was never evaluated
again.
The fix corrects the TYPE DISPATCH rather than suppressing anything:
packed ids (bit 33, GetEnvCellGeomId) answer "not yet" in the
acquire-to-prepare window — the true answer, since the scheduler
re-registers on the same landblock build — and PrepareMeshDataAsync's
blind cast becomes a typed, loud invariant failure naming the id kind
and the issue, so a future caller repeating the confusion gets a
diagnosis instead of three live hangs.
Validation: the crash was DETERMINISTIC at login cell 0xA8B4002F (two
consecutive hard failures); with the fix the same login revealed
cleanly and a full session — 16,585 entities, five portal generations,
the user-passed Session-B dungeon gate — ran with zero overflows and
zero guard fires. Clean-room suite: 11,253 passed / 6 skipped /
0 failed.
Found because the Session-B gate launch finally captured the stack the
earlier #339 hangs never printed. #343 (the wounded loop's Reset-in-
render-loop shutdown) and #344 (the mid-teleport world-frame race the
same evening surfaced) are filed separately and unfixed.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
S1B + S2's shared gate passed live ('Feels good!'), run INSIDE the
dungeon the #344 crash had conveniently saved the character at. #344
filed with its two halves kept separate: the world-frame guard is
CORRECT (it refused a 28.8 km mis-projection — do not weaken it); the
defect is the teleport-recentre ordering race plus the unhandled-crash
failure mode where a deferred retry belongs. AD-64/#324 family.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The Session-B gate launch reproduced the reveal hang at login and the
log finally carries the crash: PrepareMeshDataAsync's Setup/GfxObj arm
does checked((uint)id) on a packed 64-bit EnvCell geometry id, reached
because EnsureRenderDataReady found the id OWNED but DESCRIPTOR-LESS —
the release path removes the descriptor while render data parks on the
LRU, re-acquire restores ownership, and nothing re-registers the
descriptor until a full prepare is re-requested. The OverflowException
rides the render frame's readiness evaluation and the reveal is never
evaluated again. Demote-then-revisit ordering explains the
intermittency. S1B/S2 are not implicated: neither touches this
pipeline and the signature predates both.
Root-cause fix deliberately NOT designed in this session's tail — the
invariant to restore is owned-implies-descriptor (or a legitimate
re-request from retained data), which needs the acquire-path read the
next session starts with. Catch-and-continue and skip-64-bit-ids are
named as the band-aids they are.
#343 filed alongside: the wounded render loop's shutdown throws Silk's
Reset-inside-render-loop and abandons incomplete, exit 82.

Both static sites (LandblockPhysicsPublisher, the headless-only
LandblockPhysicsContentBuilder) emitted an authored Setup Sphere as a
base-anchored Cylinder of radius r and height 2r. The live path emits a
Sphere for the same data, so the same object collided differently by
arrival route, and the narrow phase met a flat cap where retail meets a
curved surface. Both sites now mirror ShadowShapeBuilder.FromSetup's
Sphere block exactly.
Combined Opus review: PASS. Its numeric verification of the dispatch
test's geometry (head-sphere clearance 0.201 m for the true sphere; the
cylinder counterfactual inside by 0.10 m XY with the Z band overlapping)
is what makes the discrimination claim more than a sabotage anecdote,
and its F8 finding is applied: the test now carries a POSITIVE control —
aiming straight through the boulder's centre must block — so a
membership/seed regression can no longer masquerade as a curve-hit
pass. F4 applied: CylHeight is asserted, not inferred (the C4 lesson).
F3 applied: the deleted Quaternion.Inverse base composition is recorded
as internally coherent for the old cylinder's world-Z axis — the defect
was the shape TYPE, not that rotation math.
The review also verified the deleted-cylinder blast radius: the F2
overlay's drawn span is IDENTICAL for both shapes (old [c-r, c+r], new
[c-r, c+r]); the flood sphere's centre rises by exactly r, which cannot
change outdoor membership (XY rectangle) and lands the indoor half on
Session B's dungeon gate alongside S1B; and the sphere-branch flood is
now pinned uncapped by a genuine eleventh-shape A/B test.
PublishStaticCollision — the headless static path — gains its first
test ever.
AP-155 is NARROWED, not deleted (review F13): the has-BSP source split
(entity.MeshRefs vs setup.Parts + AnimPartChanged) survives and keeps
the row active. The shared-primitive-emitter refactor that would make
route independence a compile-time property is the filed follow-up
(review F20).
Population: 3,506 of 5,935 installed Setups, structurally equal to
AP-157's third-branch count (byte-identical classifier — three
independent routes agree: 3,605 - 99 = 3,506).
Clean-room suite at implementation: 11,253 passed / 6 skipped / 0
failed on landed S1B. Post-review-hardening: Publisher tests 25/25,
Content tests 2/2, both green.

CellTransit.FindTransitCellsBox ports CEnvCell::find_transit_cells'
part-array overload @0x0052cae0 line-for-line: per-portal x per-part
order, the sphere cheap-reject at F_EPSILON+radius, the box admit whose
"Straddle or crossing-side" rule is exactly retail's `eax != side` under
the PDB Sidedness enum, leads-outside placed AFTER the admit, the
unconditional unloaded-neighbour hint without the sphere overload's
re-test, the destination box_intersects_cell gate with its deliberate
no-break, and add_all_outside_cells after the loop. The box-vs-cell BSP
traversal lands in BOTH representations behind the flat-authoritative
dispatcher with a graph referee whose 20,000 installed comparisons are
pinned by assertion (review F5), zero mismatch.
Dual Opus review: PASS on both lenses. The mandatory D0 pseudocode pass
caught that the contract's own supplementary note misattributed the box
block to the sphere overload — it belongs to a SECOND
check_building_transit overload @0x0052c680, whose portal-side
convention is INVERTED and whose admit differs; the pseudocode doc now
records that trap plus two byte confirmations made at review:
which_side @0x00444720 is strictly > eps for POSITIVE, and
intersect_box's in-plane early exit returns CROSSING(3)
(jp @0x005aa1bc -> mov eax,3), settling review items b1/b2 for the
future bridge porter. The bridge itself stays unported as AP-159's
explicit remainder.
The review also retired #335's severity premise honestly: "over-
inclusive only, never a missed one" is wrong at production shape ratios,
where the box (whole-vertex AABB) legitimately exceeds the sphere
(physics-polygon root sphere). Measured, both populations: rigged
(box << sphere) — 1,520 placements, 978 cells removed, 0 added;
production-ratio (box >= sphere) — 950 placements, 20 removed, 1 ADDED
through the loaded-neighbour gate, which is retail's direction, not a
defect. The no-op guard (review F4) asserts removal is nonzero so an
unwired admit cannot pass silently.
Process note: the implementer authored against this session's worktree
at bec5c69d, 25 commits stale — the recorded worktree-base class. All
six files were byte-identical between bases, the diff transplanted
losslessly, and every verdict-bearing run (referee, direction sweeps,
this clean-room) was re-executed on current main. S2's uncommitted
phase-1 edits were stashed for this landing so the suite verdicts
exactly one changeset.
Also untracks 341-slope-capture.jsonl (an accidental add) and
gitignores it.

AP-83/AP-91 claim no current mover sets PerfectClip. False: the camera
probe sets it, faithfully to retail's camera flags. The containment
proof therefore has a real question — whether the viewer exemptions or
the camera sweep's shape cut every chain to the ACE-derived TOI tails —
and an honest fallback if they do not: the rows get rewritten with the
camera named as the live population rather than 'unreachable'. Guard
either way, so a future flag change cannot silently start executing
math nobody re-verified.

The suspect line is pinned at scoping: our ValidateWalkable measures the
sphere's VERTICAL bottom against the plane (planted rest, perp = r*N.z)
while our AdjustSphereToPlane is already a faithful tangent port — we
mix the two geometries today and the planted one wins on terrain. D0
byte-pins retail's validate_walkable distance basis with an explicit
STOP if it refutes the premise; D2 retests the #341 harness flip ten
ways under the mechanism's stability prediction; the gate teaches the
user that slightly hovering feet on steep slopes is the CORRECT retail
look. Queued behind S1B and S2 — one physics slice in flight at a time.

The divide-by-itself artifact in the BN text resolves in Ghidra to
t = (dist -/+ r) / dot(N, stepDir): a ray-vs-plane interpolation to
perpendicular-distance == radius. Two independent decompilers agree on
the mechanism the #341 resolution rests on.

CPolygon::adjust_sphere_to_plane @0x00538210 solves the walkable
placement for perpendicular distance == radius: retail rests the sphere
TANGENT to the slope, which makes its bare-radius push-out trigger
structurally inert — and explains why our planted rest (perp = r*N.z)
makes our substituted trigger inert here by the same algebra. Each
engine's trigger matches its own resting geometry; the live A/B's 84%
fire rate is what mixing retail's trigger with our placement produces.
AD-66 is therefore not a standalone row: the faithful unit is the pair
(tangent placement + bare trigger), ported together or divergent
together. The visible corollary of the retail pair — feet floating by
r*(sec(theta)-1) on slopes, up to ~20 cm near the walkable limit — is
why the decision is queued for the user's eyes rather than taken
silently under the retail-first default.
From capture to mechanism in one morning: the user's two-minute slope
run plus one decomp read did what the overnight harness could not.

3,870 player resolves captured at Rithwic with ACDREAM_CAPTURE_RESOLVE.
Of 2,955 contact-seeded ticks the RETAINED trigger fired zero times —
the current push-out is inert in ordinary play — while retail's bare
trigger would have fired on 2,471 (84%), lifts 2-88 mm, p50 27 mm. The
body rests at r*N.z every grounded tick, so landing AD-66 alone would
engage the push on virtually every slope step and fight the foot
planting: the oscillation the original substitution was written against.
The exposed question sits upstream: our placement plants the sphere
vertically (perpendicular r*N.z); if retail's walkable contact rests
tangent (perpendicular r), retail's bare trigger is inert in retail
exactly as ours is here, and the trigger cannot be ported without the
placement geometry. That retail-side verification is now the apparatus
session's first task, and it also gives the harness flip a mechanical
suspect: settle-state order dependence, not physics.
Measured from the user's own two-minute run rather than argued — the
cheapest decisive instrument of the campaign so far.

The six-part sitting ran 2026-08-07 on the post-S4 binary: nine-stop
tour, portal repetition, the cancelled-teleport vanish-and-return,
equipped-item teleport, two-client observation, and the fresh-process
logout/relaunch cycle. Log evidence: 19 reveal generations, 17
materializations, one cancel correctly superseded by its immediate
replacement, zero hangs, zero wait-cues. The graceful-logout path
cleared the ACE session instantly and login returned to the exact last
location.
Recorded honestly rather than roundly: the placement probe families were
not armed during the sitting, so route-7's thin cause=propagate evidence
was not thickened and 4b-3's cause=cellless case remains unexercised
with an unestablished trigger. Both close as user-passed with thin log
evidence; the symptom-side gates are the regression net.
The probe-family strip is unblocked and queued behind the in-flight

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.

The slice text claimed a door's collision stays where the shut door was.
AP-84's own row refutes the scenario: an open door is ETHEREAL (#150)
and bypasses collision entirely, so a door only ever collides in its
registered default pose — the approximation is behaviourally equivalent
for the entire known BSP-part weenie population, and the row's risk
column already carries the revisit trigger for animated non-ethereal
BSP movers if they ever appear.
The campaign's governing lesson says register rows are leads that must
be re-measured; the dual of that is that a CORRECT row must not be
'fixed'. The plan itself committed the reading failure this time. No
fix, no gate, no door row in the morning sitting.

LiveEntityCollisionBuilder and LiveEntityDefaultPoseResolver move from
AcDream.App.Physics to AcDream.Runtime.Physics with no behaviour change
— diff-verified byte-identical shape math by both review lenses. The
Build signature's App-record parameter is replaced by presentation-free
primitives with identical guard semantics, INCLUDING the
FinalPhysicsState read the contract had missed and the implementer
surfaced rather than dropped. Visibility stays internal: Runtime's
existing InternalsVisibleTo grants already cover every consumer, so the
implementation's public widening is reverted per the architecture
review's finding 11.
The registration WIRING is deliberately WITHHELD. Both Opus lenses
failed it, converging: a shadow registered at spawn freezes there
(RuntimeRemotePhysicsUpdater is Runtime-homed but App-driven — nothing
headless ticks it), so a walking NPC becomes a phantom obstacle at its
spawn point while the real NPC still passes through the bot; three of
five shadow-lifetime edges leaked (pickup leaves a permanent invisible
collider, supersession orphans a duplicate, generation reset never
unregisters and the K-ledger convergence oracle only checks retained
shadows AFTER disposal clears them); and headless cannot resolve BSP
collision assets at all, so doors and chests would still be
walk-through. The frozen-shadow root was the SESSION LEAD's contract
error (fact 3), not the implementer's.
#330 stays OPEN, rewritten as the seven-point scope map the reviews
produced — the honest overnight deliverable is that map, not a
half-mechanism carrying new divergences.
Suite 11,235 passed / 4 skipped / 0 failed (the withheld seam's two
tests account for the delta from the implementation run's 11,237).

Applying feedback_register_revert_resurrection to its own discovery:
auditing every row in a8a7d64b's register hunk found the inverse defect
in the same diff. The revert resurrected retired AD-55 AND deleted
then-active AD-56 (the plumb-fall freeze adaptation, split out of TS-4
by the commit being reverted). Nothing ever restored it, and its
condition came back to life when TS-4's Path-6 shortcut deletion
re-landed for real at Slice 2B — so for eight days a live, test-pinned,
deliberately-documented behaviour had no register row, which is 'a bug
twice over' by the register's own rule.
Restored verbatim from 5e2be19b with a provenance header. One revert,
two silent register corruptions in opposite directions — the memory
rule's audit step is not optional. AD section 50 -> 51.

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.

Both static publication paths emit an authored Setup Sphere as a
base-anchored Cylinder (r, 2r) while the live path emits a Sphere for
the same data — different narrow-phase dispatch and a route-dependent
collision difference for the same object. The fix mirrors FromSetup's
step-3 emission at both sites; the contract's first test is the
route-independence property asserted shape-for-shape, and the dispatch
test picks geometry where cap-hit and curve-hit verdicts differ so the
sphere verdict is observable, not inferred.

snap_to_plane @0x00509c50 semantics extracted at scoping: XY preserved,
Z re-solved so the offset lies in the plane, no-op under the 0.0002
|N.z| epsilon — versus our orthogonal projection, which is exactly the
cos-squared downhill shortfall AD-65 recorded. Branch polarity pinned
from the test ah,0x41 idiom at 0x0050a4fa: into-plane subtracts,
away-from-plane snaps.
AD-66's port carries a mandatory regression scenario: the original
substitution was empirically motivated (uphill contact-flap), so the
contract requires that exact scenario as a test and a full STOP if the
faithful port genuinely reds it — re-filing the divergence as deliberate
is the session lead's call, not the implementer's tune.
Priority note: S4 jumps ahead of S1B in the overnight queue on felt
value — 25-50% downhill XY shortfall is daily-feel, while S1B's
over-inclusion is zero-felt fidelity. The campaign's
membership-before-query ordering is about masking, and an over-inclusive
residual masks nothing downstream.

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.

Campaign S night shift. #330's contract pins the scoping facts so the
implementer inherits measurements instead of re-deriving them: the
builder is already presentation-free logic (the only App coupling is one
identity-guard parameter), headless has full content (_content.Dats +
prepared PhysicsDataCache), shadow-sync already runs in Runtime once a
shadow exists, and the no-window inbound route is host-disjoint per
AD-64 so registration wired there cannot double-register on the
graphical host. The local-player ProvenShapeless pin is explicitly OUT —
fixing it blind risks the K-series gates.
AP-159's S1B contract maps the pseudo-C line ranges for the part-array
find_transit_cells overload, the box-vs-cell BSP traversal, and flags
the adjacent overload's Binary Ninja signature artifact for the
mandatory pseudocode step to resolve. House rule carried: a new
traversal in two representations ships with an exact differential
referee, and the direction assertion (membership strictly shrinks) is a
test, not an assumption.
Also settled at scoping, evidence in the S1A brief: AP-157's CylHeight
half is a NON-divergence — CObjCell::find_cell_list's cylsphere overload
@0x0052b9f0 copies localtoglobal(low_pt) + radius per cylsphere, capped
at 10, and never reads height; acdream's base-point cylinder flood is
exactly retail's behaviour. Register correction follows with S1A's
measurement numbers.

The three-site probe answered it in one run: prepare and publish carry
the authored 0.600/1.500 to the publication candidate, and resolve
receives exactly those values for the entire session after one early
0.400 reading. Re-reading the ORIGINAL 337-support.log with statistics
instead of an eyeball: authored pair 111,248 lines, 0.400 pair 358. The
filing was built on an early line of a 255k-line capture; the alleged
mechanism (values never wired to the mover) does not exist.
The 358 are AD-68, now registered: GetSetupMoverShape's placeholder
(empty spheres -> legacy capsule, 0.4/0.4 steps) during an entity's
async Setup-residency window, plus the local player's own seconds-long
window between controller construction and publication-candidate
adoption. Retail loads synchronously and has no such window. Left as-is
deliberately: shrinking it is streaming work.
The filing still paid for itself: three false doc-comment claims
corrected in PlayerMovementController (retail '~0.4 m' twice, and an
ApplyStepHeights writer that never existed anywhere in the tree —
replaced with the real writer chain), retail's actual fallback pinned at
0.04 (CTransition::step_up @0x0050b655), and the resolve probe now
prints the mover id, because the early 0.400 was most plausibly a
REMOTE player — remotes also carry IsPlayer — and the guid rule
(feedback_probe_identity_attribution) exists precisely to stop that
misread.
No production behaviour changed; nothing for the morning gate. AD
section 50 -> 51. Suite 11,234 / 4 / 0.

Both halves of #32 are now closed: remote at 204d0ae0 (user-passed
2026-08-04), local at 332045c7 (user-passed 2026-08-07 at the Rithwic
cliff, on the first launch whose capture printed the fixed binary's own
assembly path). The research doc carries the outcome banner: the live
capture landed in decision-table row 1 verbatim and Section 7's fix
shipped unchanged.
AD-67 records the one deliberate residual: the narrowed SetContactPlane
still writes ContactPlaneCellId, which retail writes only at
init_contact_plane (0x0050e8ca). Kept on the research doc's own advice —
our consumers want the current value — and not bundled into the fix
commit, where a second behaviour change would have made the user's
cliff gate ambiguous. AD section 49 -> 50.
Section 3.5's blast-radius items stay open as watch items, now strictly
MORE reachable than before the fix (last-known validity is narrower, so
the StopVelocity recovery and phase-3 reset take their invalid branches
more often). Carried onto Campaign S slice S4.

Two checkouts, one relative launch path. Edits and builds ran in the
main repo; every client launch ran from a PowerShell shell whose cwd was
still the session worktree, so 'dotnet run --project src\AcDream.App\...'
executed the worktree's 08-06 22:35 binary — #333 present, #32 fix,
InitContactPlane and every #338 probe absent. Byte-proof both ways: 0
occurrences of the fix strings in the worktree's Core.dll, both present
in the main repo's.
Everything the previous entry concluded is therefore void: the
byte-identical capture was the OLD code re-running (expected), the three
probe silences were one fact (the instrumented binary never ran), and
the 26,358-write attribution table is pre-fix baseline data of the old
binary only. #32's fix returns to UNTESTED, with no evidence against it.
The verification that was supposed to catch this confirmed the wrong
binary: the DLL byte-check ran against the OTHER checkout's bin. So the
self-report now prints typeof(PhysicsDiagnostics).Assembly.Location as
its second line — binary identity becomes a recorded fact inside every
capture instead of an inference from file timestamps afterwards. Memory
updated with the multi-checkout rule: absolute launch paths, verify each
shell's cwd before the first launch.

The 332045c7 fix produced a byte-identical live capture at Rithwic: same
six events, same curN == lastN, same apply=False. The user still falls
through. The commit is not wrong and is not reverted — it restores
retail's setter split and is sabotage-verified — but it closes a writer
that is not the operative one here.
Caller-attributed capture puts 26,358 last-known writes in
PhysicsEngine.ResolveWithTransition, whose only such writes are
check_contact's FAILURE branch seeding from body.ContactPlane. Recorded
with the loop that suggests (2041-2044 seeds ci from body; 2168-2174
writes body from ci) explicitly marked NOT PROVEN, because it rests on
line-number mapping from an optimised build where inlining makes
attribution approximate.
Filed with a BLOCKER at the top: an unconditional one-shot WriteLine at
the head of that same method printed zero times. Both facts cannot hold.
Three conclusions were drawn from probe silence this session and all
three were premature, so the entry says to settle assembly identity with
a check that cannot be explained away before any further work on #32 or
#338 — rather than let a fourth inference compound the first three.

Captured live 2026-08-07 with the raw log attached rather than
summarised. Generation 2 to cell 0x3032001C: render, composites and
collision are all False at begin and still all False at cancel, so
complete and world-visible never fire and the five-second wait cue sits
there until the client is closed.
Filed rather than chased, per user direction. Two things recorded
because they will otherwise be assumed: the same destination succeeded
TWICE in the previous session, so it is intermittent rather than a
broken landblock; and while it is mechanically very likely unrelated to
the #32 contact-plane change landed minutes earlier (different
subsystem, different thread), it fired on the first run after it, so the
entry says to A/B against a binary without #32 before ruling it out
rather than asserting independence.
Also flags, without assuming either way, that #280's D-1 was an
unrecoverable portal hang with the same visible symptom — this is either
that regressing or a second mechanism wearing its face.

Measured live at Rithwic 2026-08-06 with ACDREAM_DUMP_EDGE_SLIDE=1.
Six branch2/steep-cliffslide events, every one reporting
curN=(-0.954,0.000,0.301) lastN=(-0.954,0.000,0.301) angle=0.0000
apply=False, outcome degenerate-cross/last-known. That is decision-table
row 1 of the research doc, verbatim.
CTransition::cliff_slide @0x0050a6d0 takes its slide direction from
cross(steep contact normal, last_known_contact_plane.N) — it needs the
surface the mover was STANDING ON as the second vector. acdream's
CollisionInfo.SetContactPlane latched the last-known group on every
call, so by the time cliff_slide ran, last-known had already been
overwritten with the steep face itself: the cross product of a vector
with itself, which is zero. Degenerate direction, no slide, walk off
the cliff.
Retail's COLLISIONINFO::set_contact_plane @0x00509d80 is 22 bytes and
writes the CONTACT group only; the last-known group has four writers,
none of them that function. So the four writes are DELETED and a new
InitContactPlane mirrors CTransition::init_contact_plane @0x0050e850,
writing both — the start-of-transition seed, where there is no earlier
surface to remember. Only check_contact's SUCCESS branch calls it. The
other eleven call sites keep the narrowed setter. This is a port, not a
suppression: no guard, no grace period, no flag.
The user's own A/B was the discriminator: Neftet's block plateaus hold
(188 branch3/precipice-slide events, all before the teleport) while
Rithwic's terrain cliff fails (6 branch2 events, all after). I had
predicted the opposite — that terrain would be the flat-normal case —
and position plus timeline corrected me, not reasoning.
NEW DISCRIMINATING TEST, because the suite had none. It was green both
before and after the production change, so nothing in it defended this
behaviour. Issue32LastKnownContactPlaneTests seeds a walkable plane,
asserts a steep mid-transition contact leaves it intact, and asserts the
resulting cross product is non-degenerate. Sabotage-verified: restore
the four writes and both discriminating rows fail while the
InitContactPlane control keeps passing — the pair separates 'the latch
is gone' from 'nothing writes last-known at all'.
Two existing tests corrected rather than deleted.
PhysicsSetPositionTests.FailedCheck_MapsCollisionHandlerResultToRetailError
passed BECAUSE of the latch (the file the research named); its hook now
populates both groups explicitly, since it asserts report plumbing, not
setter semantics. RetailEdgeResponseOrderingTests.TransitionalInsert_
DegenerateCliffSlideOk_ContinuesOuterRetry was predicted to fail and did
not — it now passes for a DIFFERENT reason (last-known absent rather
than clobbered, which retail also answers with OK_TS). Its comment
described the deleted behaviour and is corrected to say so, and to say
it does not discriminate this fix.
Also repairs the #338 probe. Its first placement in
PlayerMovementController printed nothing across 11,523 live log lines —
the wrong one of two resolve call sites — so it moves to
PhysicsEngine.ResolveWithTransition where every caller passes through,
filtered to the player. The dead site is removed rather than left in
place; a probe that never fires is worse than none. The flag test now
precedes the interpolated string: building it eagerly cost 128 B per
resolve with the probe OFF, which Slice I1's zero-allocation gate caught.
Suite 11,234 passed / 4 skipped / 0 failed.
