68568a3a59 fix(vendor): grand-gate findings — wire-truth container counts, the live split bar, arrival-gated use, prepend-order race
Some checks are pending

Four live findings, each with the paper-verification failure named:

G1 the container-capacity guard counted containers by a local
type/capacity heuristic that over-classifies ordinary items;
retail buckets from the wire's ContainerProperties at insert. Now
reads ClientObjectTable's existing ContainerTypeHint (AP-168 narrowed
to the shop-stock half; a pre-check must never false-block).
G2 the amount bar never showed live because ACE never sets StackSize
on browse listings — DescStackSize is null for every real vendor item
and the C4 paper test hand-set the field, bypassing the materializer.
The materializer now falls back to the packed supply count (AP-169,
ACE adaptation); the new test drives the REAL materializer.
G3 an out-of-range Use now dispatches ON ARRIVAL (pickup's shape):
ACE's HandleActionUseItem only opens the vendor when the Use finds
the player in range — a click-time send is greeted and dropped
(AP-170, ACE adaptation; retail's server walks the player, ACE
does not).
G4 bought items appended because ACE's placement echo (UIQueue) can
beat the CreateObject (SmartboxQueue) — cross-queue, no ordering
guarantee — and the early echo was silently dropped. ClientObjectTable
now stashes unresolved placements and replays them at Ingest: buys
land at the retail list head. No register row — this RESTORES parity.

Clean-room complete solution: 11,521 passed / 4 skipped / 0 failed.

c68ad1e646 fix(vendor): 6b/6c review corrections — pre-send guards, accumulating staging, trade-note exemption, drag-over tab switch, full-stack sells
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run
Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
All thirteen findings, each anchored in recovered bytes or pc reads:

Buy All now runs retail's four PRE-SEND guards in order (pyreal and
alt-currency affordability, container and item slot capacity; strings
recovered from .rdata at 0x007b57b4/0x007b5750) — a rejected batch can
no longer destroy the staged list. Staged adds ACCUMULATE with the
5000 cap ("I can't possibly sell you that much!..." @0x007b59d8) and
the shop rows decrement/restore per RemoveFromShop. The max-value sell
rejection exempts trade notes — the raw bytes at 0x005d1add are `not`
(bitwise), not the pseudo-C's misleading `!`, and the early ret skips
the min check too. BF_RETAINED gates selling end to end (the bit was
already on ClientObject; AP-164's three claims were all false once
traced — RETIRED). Dragging over the vendor window auto-opens the
Selling tab per UpdateDragOver — with a correction to the review's own
citation: token 0x100000cd is the SELLING page, the guard is
"don't reopen the current tab." Sells are full-stack-only (three
retail sites; "Cannot sell part of a stack" @0x007b57ec) and Sell Item
acts on the global selection unconditionally. The confirm string gains
its byte-true trailing '?', dies with the session, staged-row
highlights repaint, dead guids unstage with retail's shopping-list
notice, and move-to-use no longer walks to targets the dispatch would
refuse.

AP-162 narrowed, AP-164 retired, AP-167/AP-168 filed honest.

Clean-room complete solution: 11,508 passed / 4 skipped / 0 failed.

92ea3977b6 feat(vendor): Slice 6b/6c — move-to-use, buy staging, selling; the vendor arc is functionally complete
Some checks are pending

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
C1 an out-of-range Use now approaches first via the existing
client-predicted BeginApproach (Pickup's far-range shape mirrored;
retail's ItemHolder::UseObject @0x00588A80 has no range check and the
dispatch stays immediate). C2 Add-to-List stages into the Buying tab
via VendorStagingList (RemoveProfileFromList's two shapes,
pc:200497-200537), Buy All sends ONE batched 0x005F and flushes
staging on send exactly as retail does (SendShopEvent -> Flush,
pc:204075-204076 — not UseDone-gated), and X-close over a non-empty
staging list shows retail's confirm string recovered verbatim from the
binary data segment (0x007b5bd8) through the existing dialog factory.
C3 the Selling tab's list is the sole drop target (retail's single
IsAncestorOfMe gate, pc:204229-204246); VendorSellAcceptability ports
InqAcceptability with all rejection strings recovered verbatim from
the raw data segment; the sell side prices with BuyPrice (retail's
inverted naming: what the vendor PAYS) and 0x0060 carries no trailing
currency field, unlike Buy. C4 the status-bar reproduction test PASSES
against the production toolbar mount — retail's toolbar shows count +
name with the split bar and NO price parenthetical (that figure is the
vendor row's own cost text); no code change, the live gate referees.
C5 pack order verified correct, untouched.

Register: AP-161 narrowed to its two pre-existing cosmetic gaps;
AP-162 extended over Buy All; AP-164 (non-sellable bitfield
unmodeled), AP-165 (DescStackSize for _maxStackSize in the removal
test, bounded), AP-166 (purse text + pending-sell highlight cosmetic)
filed.

Clean-room complete solution: 11,482 passed / 4 skipped / 0 failed.

33b45ee581 fix(ui): vendor dropdown polish — authored arrow-cap with open/closed flip, downward popup, left-aligned rows
Some checks are pending

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
Three gate findings, each settled by authored data rather than
invention: the button face is retail's two-piece assembly and the
17x19 arrow-cap 0x1000034E now renders with its authored
Normal(closed)/Highlight(open) states; the popup direction is an
AUTHORED attribute (UIElement_Menu::Open pc:120210-120252 — bool
attr 5, chat authors upward=true, the vendor menu authors nothing and
defaults downward), so both menus are now byte-faithful with no
special case; and the 19/20px text indents were chat-specific
checkbox/LED clearances the vendor rows don't author — measured
against the live retail font, "Spell Components" overflowed by 11px
and now fits with 8px to spare. Chat's menu defaults are bit-identical
and its tests untouched.

AP-161's arrow-cap note closes. #351 files the pre-existing FarLoad
Debug flake (three sightings today, never in clean-room Release).

5224e43890 fix(vendor): gate-findings pass — the X button HIDES like retail, clicks return, the dropdown scrolls, pyreal suffix, staged-tab slots
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run
Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
The user's connected gate found five issues; each fixed at the root:

G4 (the discovery): retail's vendor X button calls only SetVisible(0)
(pc:204147-204182) — the SESSION stays open and re-using the vendor
lands on the same-session refresh; the range watcher remains the sole
real close. Our port invented a full teardown on X, which is exactly
why reopening died. The Runtime fixture proves the wire dispatch was
never the problem; ACE has no already-open short-circuit.

G3 (regression from the drag-suppression fix): denying IsDragSource
also dropped press capture, so clicks fell through to window-drag.
UiItemSlot.HandlesClick now claims presses for any occupied cell
independent of drag eligibility — clickable and draggable are separate
concerns.

G5: the authored popup 0x21000043 is ONE scrollable column with a real
scrollbar subtree (live-dat scan: ListBox 0x10000350 + scrollbar
0x10000351), not a 3x6 grid. UiMenu gains an authored-driven
Scrollable mode (wheel, thumb drag, track paging, up/down buttons);
chat's menu is untouched and its ten tests prove it.

G1: retail's cost format is "%s %hsp (you have %hsp)" — the p after
each %hs is a LITERAL pyreal suffix the port swallowed as part of the
specifier. Restored.

G2: the Buying/Selling pages' authored lists (same cell template as
Items) get the empty-slot fill, presentation-only until staging.

Clean-room complete solution: 11,390 passed / 4 skipped / 0 failed.

58c8de264e fix(render): #350 — the shadow ledger's lifetime counters are 64-bit; the 2h42m overflow is closed
RenderDeltaApplyResult's nine counters accumulate for the lifetime of
a world generation (the cumulative sum is never reset in place) yet
were int where every sibling lifetime counter in the same class was
already ulong/long. A 2h42m single-generation session (login to crash
with zero portals) overflowed one through ordinary per-tick churn from
SynchronizeActiveSources' two call sites per frame. Introduced
0eb66485 (2026-07-24); first reached by the vendor buy gate because
parking at a shop for hours produced the project's first multi-hour
unbroken generation. The vendor materializer was exonerated by routing
analysis (shop-item Ingest/Remove reaches inventory deltas only, never
the render journal).

Widened to long; the per-tick builder stays int and widens implicitly;
the arithmetic stays checked. All 68 render-shadow tests green.

3c9fc57adb fix(vendor): Slice 6 review corrections — ownership-checked retire, live slider display, drag-proof shop rows, hardened buy reservation
Some checks are pending

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
All nine findings from the buy-arc review, at root:

F1 the materializer's retire pass re-checks ownership (guid->vendorId
map; remove only while the live object's ContainerId still equals the
recording vendor) — buying a player-sold UNIQUE no longer deletes the
item you just purchased; the discriminating reparent-then-refresh test
pins it. F2 the cost/name display subscribes to the live split state
and shares ONE quantity computation with Buy (retail re-renders per
slider tick: RecvNotice_StackSliderChanged 0x004C4500) — the sentence
and the charge can no longer disagree. F3 shop rows never mint drag
payloads (UiItemSlot.AllowDragSource gates both IsDragSource AND
GetDragPayload — the second gate was caught by this pass's own test).
F4 sendBuy reports whether anything was sent; a null-session buy
cancels the reservation instead of leaking BusyCount forever.
F5 the retire loop snapshots, isolates per-guid observer failures, and
clears its tracking in finally and Dispose — teardown convergence can
no longer wedge. F6 auto-select is retail's unconditional
first-filtered-item shape (pc:201180-201184; the survival-check was
our invention and the comment claiming otherwise is corrected).
F7 non-stack buys clamp to quantity 1 locally (BuySingleItem
pc:201669). F8 the Add button is hard-disabled until staging exists.
F9 AP-161/162/163 rewritten to the post-fix reality.

Clean-room complete solution: 11,378 passed / 4 skipped / 0 failed.
The #350 render-ledger overflow observed this session is under
separate investigation and is NOT addressed here.

97cf873870 feat(vendor): Slice 6 buy arc — shop items are real objects, vendor selection is THE selection, and Buy works (0x005F)
Some checks are pending

Headless portability / linux-vulkan (push) Waiting to run
Three ordered pieces in one landing (the shared controller/composition
files carry all three; the internal order was 6.1 -> 6.2 -> 6.3):

6.1 VendorShopItemMaterializer diff-merges the shop list into the live
ClientObjectTable on VendorState transitions (so client-local close and
session teardown retire the entries too) and never claims a guid it did
not add — ACE's UniqueItemsForSale can re-list a guid a player once
held (AP-163 files the collision-skip; no retail counterpart traced).
Right-click examine on shop items now routes through the ordinary
appraisal path — the 5.4 F7c blocker dissolves with the table entries.

6.2 SelectionChangeSource.Vendor: row clicks, auto-select, and examine
all flow through the canonical SelectionState; the status bar and the
existing byte-faithful StackSplitQuantityState slider light up
unmodified. VendorSplitPolicy is the single 0xDC41CB0 mask owner; the
slider VALUE seeds to 1 for exempt items while maxSplitSize keeps the
stack (the splitSize/maxSplitSize distinction, research §B.3).
Selection clears at retail's actual site — VendorItemsUI::RemoveFromShop
(pc:202848), not a CloseVendor-level clear that does not exist.

6.3 BuildBuy (0x005F): vendorGuid, count, (i32 amount, u32 guid) pairs,
and the trailing alternateCurrencyId the REAL client sends
(CM_Vendor::Event_Buy pc:689288) though ACE's reader ignores it.
TryBuy rides the EXISTING J5.2 one-request-at-a-time reservation and
completes on UseDone; the Buy button disables while a request is in
flight. The reconciliation round-trip (money property update, inventory
CreateObject, ApproachVendor refresh -> panel rebuild) is proven by a
synthetic-inbound test against existing machinery — no new owner.

Register: AP-161 narrowed (selection + examine residuals close;
staging/Sell remain; double-click-to-buy confirmed ABSENT from retail
with negative evidence cited — we match retail). AP-162 files the
conscious no-client-side-affordability-precheck deferral.

Clean-room complete solution: 11,368 passed / 4 skipped / 0 failed.

e602f84be2 fix(ui): Slice 5.4 review corrections — the dropdown renders from its authored popup, retail cost semantics, auto-select, icon overlays

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
All nine review findings closed at root (one sub-item consciously
deferred):

F1 the category dropdown now draws: sprites/fonts wired and the popup
geometry read from the vendor menu's own authored popup LayoutDesc
0x21000043 (root 0x1000034F — correcting the review's 0x1000014F
transcription) per UIElement_Menu::MakePopup (pc:120705); chat's menu
is untouched and its tests prove it. The new test drives selection
through the REAL open/hit path the review flagged as bypassed.
F2+F3 the selected-item cost display ports VendorItemsUI::UpdateItemsUI
verbatim: quantity via the 0xDC41CB0 split-size mask (whole-stack for
ammo, per-unit for groceries/components; mask lives at the toolbar
SEEDING site pc:198784), plural names with retail's
fall-back-to-singular (pc:409056 — correcting the review's "name+s"
guess), full cost sentences with comma grouping and the player's coin
total, and Buy/Add buttons that disable without a selection.
F4 category switches auto-select the first filtered item (pc:201180).
F5 icon underlay/overlay/effects + plural name forwarded from the
already-parsed wire fields through VendorShopItem to the icon
composer. F6 a DIFFERENT vendor opens on its own first category;
same-vendor refresh preserves per the clamp. F7 scroll resets on
rebuild and authored empty slots fill; the right-click examine route
is consciously DEFERRED (shop items are not in ClientObjectTable and
the appraisal panel hard-requires it — documented, not faked).
F8 VendorState.Apply's fanout gets the same per-listener isolation as
Close/Reset. F9 AP-110/AP-161 wording corrected ("quantity-correct
pricing") and AP-161 rewritten to exactly the remaining conscious
gaps.

Clean-room complete solution with the #348 cursor fix in the same
tree: 11,334 passed / 4 skipped / 0 failed.

9d3df5f627 fix(app): #348 — cursor switches ride a process-lifetime native cache; the per-flip Win32 handle leak is closed
Silk's per-mouse ICursor recreates the native Win32 cursor on every
Image assignment; a per-frame cursor alternation (the pick cursor
flickering between kinds while hovering an ANIMATED NPC — exactly the
stand-at-a-vendor posture) allocated a fresh USER handle each flip
until CreateCursor died with "Not enough memory" and took the render
loop with it (vendor-gate.log, exit 82 — surfaced as one clean stack
by #343's fix, as designed).

GlfwCursorCache restores retail's own shape: each distinct
MediaDescCursor is created ONCE for the process lifetime
(glfwCreateCursor, rejected media cached as permanent misses) and
switching is an O(1) zero-allocation glfwSetCursor. The AP-72
missing-art standard-cursor fallback rides the same cache
(Arrow/Hand/Crosshair/IBeam; anything else keeps the Silk path).
Graphical hosts attach after the native window exists; tests and
windowless hosts keep the Silk path untouched. RetailCursorManager's
dedup and PlanApplication logic are unchanged.

c721830e71 feat(ui): Slice 5.4 — the authored vendor browse panel (LayoutDesc 0x21000012)

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
The vendor window is retail's own: LayoutDesc 0x21000012, root
0x100000B7, found by enumerating all 101 layouts for the one
containing both known tab controls and clinched by the root's Type
0x10000017 — the literal UIElement::RegisterElementClass id for
gmVendorUI (pc:202075). Discovery evidence and the D0 read live in
the research doc's new §B.4.

D0 corrected two assumptions: retail's category "tabs" are a UiMenu
DROPDOWN fed by a hardcoded 18-row ordered category table (ported
bit-for-bit against our ItemType enum; list always scoped to exactly
one category, first-present wins, selection preserved across refresh
per retail's clamp), and the layout authors THREE tabs — Items
(browse, this slice), Buying and Selling (staged-transaction review,
Slice 6) — decision 4's "browse/Buy tab" names the Items tab retail's
mode-2 OpenTab opens. The non-default tabs render and switch pages
but stay inert, fenced in comments.

VendorUiController mounts Items: category dropdown, icon-cell item
row with the retained scrollbar, per-unit retail pricing via
VendorPricing.SellPrice (the vendor-stock path VendorProfile::
VendorSellPrice feeds), name/cost on selection. The panel is a pure
projection of VendorState — opens on populate, closes on clear; the
close button's VendorState.Close() is its only permitted mutation.
Nothing on the wire.

AP-110 narrowed (vendor leaves the absent-panels list); AP-161 files
the precise Slice-6 remainder (Buying/Selling unwired, Buy/Add
buttons, InqAcceptability). Twelve controller tests on a real-dat
fixture. Clean-room complete solution: 11,323 passed / 4 skipped /

609a2dfda0 fix(runtime/core): Slice 5.3 review corrections — retirement/transit close, per-unit pricing, guarded auto-close dispatch
Some checks are pending

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
The adversarial review's three blocking findings, each fixed at root:

1. A vendor session now CLOSES when its entity retires (despawn,
   death, ObjectDelete) and at teleport BEGIN
   (HasPendingTeleportStart || IsTeleportActive at the existing
   per-frame seam — both hosts funnel through
   RuntimeWorldTransitState.TryQueueTeleportStart, which flips the
   pending flag strictly before activation). The previous permissive
   early-return stranded the session forever: panel pinned to a stale
   guid, ActiveVendorId swallowing Use for the rest of the session.
2. VendorShopItem carries the desc's stack size, and
   VendorPricing.PerUnitValue ports retail's stack-total division
   (VendorProfile::VendorSellPrice 0x005D1B00: <= 0 guard, integer
   division) — a stack of 50 arrows now prices per arrow, not at 50x.
3. VendorState.Close() guards its observer fanout with the
   dispatcher's catch-and-log semantics — a throwing panel listener
   can no longer propagate into the unprotected per-frame path.

Register honesty rides along: the 0.6 m UseRadius fallback was
acdream's invention (ACE's CheckClose has no fallback; retail passes
the raw authored radius) — removed, the watcher now uses the raw
radius and AP-160's citations are corrected and extended with the
accepted-position-snapshot cadence; AD-72 files VendorPricing's
double-vs-x87-extended narrowing (AD-33's class, bounded by the
±0.1 margin).

Nine tests added. Clean-room complete solution: 11,311 passed /
4 skipped / 0 failed.

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
The sole VendorState joins the J4.2 inventory owners: populated by the
new 0x0062 ApproachVendor route (parse via VendorApproach, wire-to-
domain mapping at the routing seam, silent-drop on malformed like every
sibling), borrowed by both graphical and headless hosts, and torn down
through the EXISTING ExternalContainer reset stage — session reset,
portal-out, and logout all funnel through the one mechanism. Close is
client-local per retail (nothing on the wire): a range watcher rides
the existing per-advanced-frame publishMovement callback, using the
vendor's own authored UseRadius (ACE's 0.6 m fallback when absent).
The dormant ItemInteractionController ActiveVendorId seam is finally
wired as a live delegate — real id while open, 0 the moment the
session clears.

AP-160 filed in this same commit: the watcher measures plain 3D center
distance rather than retail's cylinder-gap, because Runtime has no
per-NPC collision radius/height source; bounded sub-meter, client-
local UI only.

Twelve Runtime tests: populate/field mapping, vendor replacement,
range clear + within-range retention, all three generation teardowns,
the ActiveVendorId seam, malformed-event drop. Clean-room complete
solution: 11,302 passed / 4 skipped / 0 failed.

VendorState sits beside ExternalContainerState (contract decision 1)
with the same shape: private setters, Changed event, Reset with
AggregateException fanout; domain-shaped like ContainerContentEntry
since Core cannot reference Core.Net. No Runtime wiring, no UI — 5.3's
job.

VendorPricing ports ShopSystem::BuyPrice/SellPrice (0x006B6120/
0x006B6180) faithfully: retail's literal three-way branch survives,
including the unreachable-with-real-data negative -1 sentinel that
ACE's Math.Max(1, ...) collapse erases — equivalence for legitimate
inputs is hand-proven and documented rather than silently assumed.
Seven conformance tests with hand-derived golden values (float32
semantics verified independently), covering rate=1.0, fractional
rates, value=0, the rounding-sensitive halfway case, stack
multipliers, the ItemType rate-override branch, and the sentinel.

e45c95b06c feat(net): Slice 5.1 — ApproachVendor (GameEvent 0x0062) inbound parser
VendorApproach.TryParse reads the vendor profile and the item list per
the byte-verified field table (research doc §A.2), each item through
the shared PublicWeenieDescParser from 5.0 — zero duplicated parsing.
One wire detail the research table did not spell out, found by
re-reading ACE's writer and confirmed independently in Chorizite's
generated readers: every object body is 4-byte-aligned at its END, so
back-to-back vendor items need an explicit AlignTo4 between entries
(CreateObject never needed it — nothing follows its body). Pinned by a
dedicated test forcing a real 2-byte misalignment via AmmoType.
Stack-size sign extension cross-checked against holtburger.

Six tests: field-order with distinct literals, empty list, and
truncation at each structural boundary — mid-item-tail truncation
deliberately inherits 5.0's established non-throwing partial-item
contract instead of asserting null everywhere.

7bd4388b6b refactor(net): Slice 5.0 — extract the PublicWeenieDesc body parser for shared use (behavior-preserving)
Some checks are pending

Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
The WeenieHeader fixed prefix plus the ~300-line conditional
optional-tail cascade moves verbatim from CreateObject.TryParse into
PublicWeenieDescParser.Parse (PublicWeenieDescBody.cs), so Slice 5.1's
vendor-item parser can share it instead of duplicating it — each shop
item on the wire is a full CreateObject-style PublicWeenieDesc
(research doc §A.2). Same field order, same nested try/catch swallow
shape, same truncation messages; CreateObject composes its Parsed from
the returned record. Zero test files changed; Core.Net tests 764/0/0
unchanged; clean-room complete solution 11,271 passed / 4 skipped / 0
failed.

Per the Slice 5 contract (decision 2): extraction FIRST, as its own
bisectable commit, before any vendor code exists to call it.

ab89ebdf92 fix(physics): #345 — a grounded mover glides along a too-steep face; validate_walkable's return is scoped as retail's bytes scope it
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run
Headless portability / portable-headless (windows-latest) (push) Waiting to run

Headless portability / linux-vulkan (push) Waiting to run
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.

Suite: clean-room complete solution 11,271 passed / 4 skipped / 0
failed; Core assembly re-run green after the review-driven test

10efb5b1f9 fix(physics): AD-66 relands — the push-out uses retail's bare radius; plant-then-lift complete (#341 closed)

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.

6c6664a685 fix(app): #343 — a wounded render loop defers the native release instead of throwing over the real failure
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run
Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
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).

Queue: #344 done, #343 done; next #345's instrumented mechanism

52bdf4df71 fix(world): #344 — a mid-teleport world-frame disagreement defers the projection instead of crashing
Some checks are pending

Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
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

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.

205379c6d6 fix(streaming): #339 — a packed EnvCell geom id no longer misroutes into the 32-bit prepare arm
Some checks are pending

Headless portability / linux-vulkan (push) Waiting to run
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.

9671af0273 fix(physics): S2 — static publication emits authored Spheres as Spheres (AP-155 narrowed)
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run
Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
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.

Clean-room suite: 11,248 passed / 6 skipped / 0 failed.

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).

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).

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.

9b9bb6515f docs: the #32 'fix failed' verdict is VOID — the tested binary never contained the fix
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run

Headless portability / linux-vulkan (push) Waiting to run
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.

332045c7ad fix(physics): split set_contact_plane from init_contact_plane (#32 local edge-slide)

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.

45d7154712 probe(physics): ACDREAM_PROBE_STEP_HEIGHTS — three readings along #338's chain
Some checks are pending
Headless portability / portable-headless (ubuntu-latest) (push) Waiting to run
Headless portability / portable-headless (windows-latest) (push) Waiting to run
Headless portability / linux-graphical (push) Waiting to run
Headless portability / linux-vulkan (push) Waiting to run
The live reading of 0.400 says the controller held its default at that
instant, not why. Two very different causes produce it: the
Setup-derived prepare/publish path never runs for the local player, or
it runs and a later writer clobbers the result. Fixing without knowing
which is a coin flip.

One reading at each hop — prepare (Setup value computed and scaled),
publish (assigned to the controller), resolve (what the resolver is
actually handed) — with a decision table on the flag mapping each
pattern to its cause, including the 0.000 case that would mean a null
Setup took the retail dummy path.

Edge-triggered per site, so the per-tick resolve site prints once per
distinct pair and cannot drown the two one-shot sites it exists to be
compared against. Prepare prints the raw authored pair beside the
scaled one, so a surprise separates wrong-Setup from wrong-scale
without a second run.

Lives in PhysicsDiagnostics per code-structure rule 5 rather than as
per-call-site env reads. Zero cost when off.

Suite 11,231 passed / 4 skipped / 0 failed.

ea83b043df fix(physics): delete the query-site broadphase reach filter (#333, closing #337)
Transition.FindObjCollisionsInCell discarded a shadow candidate when
  |currPos - obj.Position| > sphereRadius + obj.Radius + movement.Length() + 2f

obj.Position is the part ORIGIN; obj.Radius is the physics-BSP ROOT
BOUNDING SPHERE's radius, measured about a centre AP-156 established is
frequently metres from that origin (376 of 973 installed physics-BSP
parts sit further from their part origin than half their own radius,
worst 20.762 m). Geometry deep inside the real bounding sphere was
therefore thrown away before BSPQuery ever ran: solid near the origin,
permeable in a bounded shell beyond it. For the Neftet rock 0xC8766009 /
gfx=0x01004751 the two points are 23.556 m apart, which is #337 — wedged
on the plateau, jumps sinking into the mesh, corpses falling through. A
live capture recorded 7,225 rejections on that one owner, every single
one with wouldAcceptAtCenter=True.

Deleted rather than re-centred. Retail has no distance pre-filter,
disassembled from the PDB-paired v11.4186 binary (CodeView GUID
9e847e2f-777c-4bd9-886c-22256bb87f32) rather than read from Binary Ninja:

  CObjCell::find_obj_collisions @0x0052b750 walks shadow_object_list and
  calls CPhysicsObj::FindObjCollisions (0x0052b78b) UNCONDITIONALLY; its
  only early-out is insert_type == INITIAL_PLACEMENT_INSERT (0x0052b759).
  CPhysicsObj::FindObjCollisions @0x0050f050 contains no float compare at
  all. CPartArray::FindObjCollisions @0x00518180 is a bare do/while over
  parts, and CPhysicsPart::find_obj_collisions @0x0050d8d0 is two null
  checks plus a call. Retail's only spatial rejection is the BSP node
  bounding-sphere test inside the walk — correctly centred, which is
  exactly what the deleted filter was not.

Re-centring it (carry BoundsCenter on ShadowEntry) would have preserved
an invention retail does not have, including a +2f slack and a
movement.Length() term with no retail counterpart, and left a second
reach budget to be tuned forever. Retail's own cross-cell slack constant
is F_EPSILON = 0.0002 m, not 2 m.

The method's comment claimed the filter was "the analog of the part
sorting-sphere early-outs inside retail's CPhysicsObj::FindObjCollisions
— response-neutral, pure perf". Both halves were false and cost #333 and
#337; it is replaced by the disassembly above.

Gate: Issue333BroadphaseReachFilterTests drives the production path
end-to-end (ResolveWithTransition -> FindObjCollisionsInCell ->
CollisionTraversal) on a DAT-free fixture so it runs everywhere, as a
discriminating pair. Sabotage-verified: restore the pre-check and
OffCentreBspFloorStopsAFallingMover reaches z=37.800 — exactly the
unobstructed fall, blockedAtLeastOnce=False — while
CentredBspFloorStopsAFallingMover keeps passing. Without the control a
fixture unable to fall would pass the first test for the wrong reason.

Issue337's skipped TheBroadphaseAdmitsTheSurfaceTheMoverIsStandingOn
asserted the now-deleted predicate and could never have gone green; it
is rewritten as installed-DAT evidence pinning BOTH halves of the
diagnosis and is no longer skipped.

Perf measured, not assumed (Release, synthetic all-BSP cell, per
ResolveWithTransition): at 38 candidates — the live maximum — 10.61 us ->
16.68 us (1.57x); at a deliberately unreachable 200, 17.34 -> 39.48 us
(2.28x); ~0.16 us per additional candidate tested. Over 19,701 live
[reach-q] samples the in-cell count is p50 = 9, p99 = 32, max 38.

The ACDREAM_PROBE_REACH rejectedReach column is kept and is now
structurally 0, so a post-fix capture stays comparable with the pre-fix
one; dropping it would make the two incomparable.

AP-158 retired (110 active AP rows). #333 and #337 closed pending the
user's live acceptance at Neftet.

Solution suite 11,231 passed / 4 skipped / 0 failed.

49a7e90652 probe(physics): ACDREAM_PROBE_SUPPORT + ACDREAM_WIRE_MESH — separate #337's three candidates
The user is wedged at the top of Neftet rock plateaus, jumps sink into the
mesh, and a corpse falls straight through. ACDREAM_PROBE_REACH already ruled
out its own domain: blocked=0, every candidate tested-ok. Three candidates
remain — terrain support, a collision mesh not where its visual is, or the
transition wedging on an unobstructed path.

ACDREAM_PROBE_RESOLVE alone cannot separate them. It prints a three-value
contact-plane token, no plane normal, no plane height, no terrain sample and
no plane provenance, so all three produce the same line. Two additions:

[support] — one line per resolve for EVERY body, not just the player. A corpse
is a plain physics body with no player-specific logic, so its fall-through is
the cheapest available control on "movement code vs geometry data", and it is
invisible to any player-filtered probe. The line samples the outdoor terrain
INDEPENDENTLY at the body's own out-XY and prints the contact plane's own
height at that same XY. Two heights at one point make support=terrain /
object / none a measurement rather than an inference, and cpSrc= names the
site that asserted the plane so provenance and classification cross-check.

[geom] — once per GfxObj that comes near a mover: the object's physics-BSP
vertex cloud against its visual mesh AABB in the same local frame, through the
same prepared accessors the resolver queries. verdict=coincident REFUTES the
working hypothesis for that object outright; no-physics-bsp / empty-physics-bsp
/ displaced / extent-mismatch each name a specific data defect. Built to
refute, not to confirm — two diagnoses on this defect's lineage have already
been refuted by measurement.

ACDREAM_WIRE_MESH upgrades the existing F2 overlay, which drew a broadphase
proxy cylinder for BSP objects and so could not answer the question at all, to
the real physics-BSP polygon edges (cyan) beside the visual mesh box (magenta)
and the terrain surface (yellow). Own class per code-structure rule 1.

The provenance latch lives on PhysicsDiagnostics, not on CollisionInfo. Two
fields there first — the obvious home — broke the flat/graph differential
referee and the scratch-reset poison test, both of which compare CollisionInfo
member-for-member. Teaching either to skip a member is a one-line green fix
that puts a permanent hole in a referee whose whole job is comparing
everything. Captured as feedback_probe_state_off_compared_types.

Seven tests cover the support classifier's boundaries: a wrong classifier does
not fail to answer, it answers confidently wrong.

Gates: Release build 0 errors; complete suite 11,225 passed / 4 skipped / 0
failed from a cleaned tree — baseline 11,218/4/0 plus exactly the seven new
tests, skips unchanged.

Issue #337 filed with the symptom set, what is ruled out, and a table of what
each possible output means. All of this is TEMPORARY and recorded for
stripping with the physics-probe family.

13fcf38138 fix(physics): port retail's find_bbox_cell_list outdoor extent walk (#334)
acdream had never implemented retail's SECOND cell-membership algorithm.
CPhysicsObj::calc_cross_cells @0x00515230 tests HAS_PHYSICS_BSP_PS at
0x00515285 and jumps (0x0051528f jne 0x515305) to find_bbox_cell_list
@0x00510fc0 for a BSP-bearing object; everything below that jump is the
OTHER algorithm, CObjCell::find_cell_list, and that is all we had. Every
object, BSP-bearing or not, was routed through it.

That path's outdoor expansion is a HARD CAP of one cell in each direction.
CellTransit.AddAllOutsideCells computes minRad = radius, maxRad = 24 - radius
and adds at most the eight neighbours of the sphere's own cell, so for any
radius >= 12 m both boundary tests are unconditionally true and the result is
exactly 3x3. Widening the radius or adding a second sphere is mechanically
incapable of adding a tenth cell. The user's live probe measured the
consequence directly: standing inside a Neftet formation, inCell=2 exempt=2
reached=0 -- the geometry was not a candidate at all.

The port. AddAllOutsideCellsFromParts is CLandCell::add_all_outside_cells
@0x00533360 plus add_cell_block @0x005331d0: base landcell from the FIRST
part's own adjust_to_outside, baseX/baseY within-block, each part's authored
CGfxObj::gfx_bound_box re-fit through all eight corners
(BBox::LocalToGlobal @0x005b2120), floor(v / square_length) where
square_length = 0x7c920c = 24.0f, four accumulators seeded to zero, ONE
rectangle unioned across all parts, FILLED, in GLOBAL lcoords so it crosses
landblocks freely, clamped only to [0, 0x7f8).
BuildShadowCellSetFromParts is find_bbox_cell_list's worklist.
RegisterMultiPart dispatches on the same flag retail does, and
BuildFloodSpheres' BSP arm is deleted rather than left unreachable.

Disassembled from the PDB-paired 2013-09-06 binary, not read from Binary
Ninja: BN mis-renders four separate constructs inside add_all_outside_cells
alone -- a dropped `and eax,0xffff` on baseX, a neg/sbb/and select shown as
identically zero, a wrong get_landcell argument, and both x87 flag tests as
`unimplemented {test ah}`.

ShadowPartGeometry pairs the BSP root sphere with the authored box so no
resolver can answer one and leave the other call site to synthesize a
substitute -- the AP-156 invariant applied a second time, since that split is
what produced AP-156 and then this. The box comes from
FlatGfxObjVisualBounds, already computed by exactly CGfxObj::init_end's
algorithm and already in the prepared package: no bake change, no DAT re-read.

Cost, measured over the installed DATs before any code was written: 1,258
physics-BSP GfxObjs, cells/object p50 4, p90 4, p99 12, max 49. The port is
CHEAPER than the old 3x3 = 9 for 98.97% of them. Row totals (shapes x cells)
over all 1,031 landblocks with BSP owners fall 97,173 -> 15,607 (0.161x);
dense Arwic 0xC6A9 falls 342 -> 43. One landblock more than doubles.

Precondition confirmed before pinning any expected cell set: 0x010046D8's box
is 96 m x 96 m about cell (2,2) = 0x87640013, which independently corroborates
the 3x3-centred-there diagnosis, and its rectangle does contain 0x87640011 and
0x87640019 -- the two cells the probe measured empty.

Register: AP-156's outdoor half CLOSED and its risk column CORRECTED (it read
"extra broadphase candidates, never a missed one", which generalised the indoor
direction to the whole row and is why #334 sat inside it unnoticed). AP-159 +
issue #335 file the unported indoor arm; AD-49 records the seed-time rectangle.
Issue #336 files a fourth load-sensitive test flake seen once during the gate.

Ten tests, every one sabotage-verified in both directions across eight
mutations (dispatch, 8-corner refit, floor-vs-truncation, union-vs-per-part,
map clamp, adjust guard, landblock clamp, box-path-for-everything). The
strongest is an installed-DAT replay of the user's own probe evidence.
Suite 11,208 -> 11,218 passed / 4 skipped / 0 failed; the +10 is exactly the
new tests.

b61f5fd4fc probe(physics): ACDREAM_PROBE_REACH — discriminate #334's three candidates
#334 is "large static formations can be walked through on flat ground, and
jumping over them drops you inside" (Neftet, user-reported, pre-existing —
reproduced on 52175aa1, before AP-22/AP-152/AP-156/AD-10). The report as
originally filed pointed at one mechanism. The user's clarification that the
formations are permeable on the ground generally, not only at a boundary
between two of them, widens it to three, and a DAT sweep can only say which
objects COULD fail, never which one IS failing at the spot. So: measure in
game, at the failing spot, and let the log choose.

The three outcomes this probe must tell apart, at the player's own collision
query:

  (a) the object IS a candidate in the cell and the broadphase reach filter
      rejects it before its BSP is consulted — AP-158 / #333. That filter
      measures |currPos - obj.Position|, the part ORIGIN, against the BSP
      root sphere's RADIUS plus an acdream-invented 2 m slack. The sphere's
      CENTRE is frequently not the part origin (376 of 973 installed
      physics-BSP parts sit further from it than half their own radius;
      worst 20.762 m), so geometry well inside the sphere can be rejected.
  (b) the object is not in the cell's candidate set at all — a membership or
      registration failure. AP-156's territory, which did not fix this.
  (c) the object is a candidate, is not rejected, and still contributes
      nothing because no usable physics BSP resolves for it.

Two line types from Transition.FindObjCollisionsInCell:

  [reach-obj] one per candidate, carrying mover guid, target entity id,
      GfxObj id, cell, and its disposition — exempt-self, exempt-missile,
      rejected-reach, exempt-rule, exempt-ethereal-stepdown, no-shape,
      bsp-only-skip, tested-{ok,collided,adjusted,slid}. For BSP candidates
      it also carries the origin-measured distance the filter used, the
      centre-measured distance it should have used, the budget, the
      shortfall, and wouldAcceptAtCenter — the boolean that separates a
      false rejection from an honest one. Identity is on every line
      (feedback_probe_identity_attribution).
  [reach-q]   one per cell query, with the per-disposition tallies AND the
      raw entry count, emitted EVEN WHEN THE CELL YIELDS ZERO. That last
      part is the point: without it, an absence of rejection lines could
      not distinguish "nothing was rejected" from "nothing was there", and
      a criterion that cannot fail in the presence of the bug it exists to
      catch is the trap this campaign has already been caught by once.
      `blocked` is the control — it proves the probe can see a working
      collision as well as a missing one.

The BSP root sphere is resolved through the SAME production accessor
registration uses (GetFlatGfxObj(id).PhysicsBsp root node, per
LiveEntityCollisionBuilder and ShadowShapeBuilder), so the probe cannot
report geometry differing from what the registry actually emitted — AP-156's
lesson was exactly that: one resolver.

Volume: [reach-obj] de-duplicates per (mover, target, cell) and re-emits at
once whenever the disposition changes or the shortfall crosses a 0.5 m
bucket, otherwise at most once a second; [reach-q] de-duplicates per (mover,
cell) on the whole tally tuple, so any change in what the cell yielded emits
immediately, otherwise at most twice a second. Both emit eagerly on change —
which is exactly when the player walks into the formation — and go quiet
when nothing is happening. Nothing is aggregated away.

Filtered to the player mover, matching PhysicsResolveCapture, so NPC and
remote dead-reckoning resolves do not pollute the capture. The helper is
static and takes everything by parameter so no closure display class enters
the resolve path: Slice I1's 0 B/resolve budget holds with the probe
compiled in and switched off.

TEMPORARY. Strip with the rest of the physics-probe family once #334 is
scored; both the flag and the call site say so.

Clean bin/obj, Release build, full suite 11,208 passed / 4 skipped / 0
failed.

e6457cc849 fix(physics): close the AP-156 fix review — real containment oracle, type-level invariant, AP-158
Both review lenses PASSED; this is the cleanup, not a rescue. Evidence:
docs/research/2026-08-06-ap156-review-closure.md (the review itself is
committed alongside it as the received artifact).

R1 — the load-bearing containment test could not fail. Its truth and flood
values were two hand-copies of the same expression over the same part set,
so the shortfall was algebraically identically zero for any DAT input. The
oracle is now PHYSICS-POLYGON VERTICES — a different DAT field from the
bounding sphere the builder emits, so the two sides can genuinely disagree.
Sabotage-verified three ways after full cleans: dropping the bounds centre
in production reddens it (428 Setups, worst 35.869 m on 0x0200129A, matching
an independent out-of-repo sweep exactly); dropping only the scale on the
centre reddens it (326); and corrupting the TEST's own bounds oracle reddens
it (467) where under the shipped oracle that same corruption was invisible
by algebra. Renamed accordingly. A6's stale "cap control" comment corrected:
that loop is the test's own uncapped re-implementation and cannot observe a
cap regression — the cap is covered in Core.

R2 — the population was understated. 172 is AP-152's DISPATCH population;
AP-156's is 530 BSP-bearing Setups, of which 525 have a flood sphere move
and 428 fail vertex containment before the fix (412 at a 1 cm tolerance —
the review's figure; the gap is 16 Setups between 1.4 mm and 10 mm, real
geometry). 0 fail after, at any tolerance down to zero. Corrected in the
AP-156 row, the section-3 header, the C5c handoff and two test docstrings.
Dated review artifacts are left as written — "170 of 172" was correct for
what they measured, and rewriting evidence to match a later measurement
loses provenance.

A1 — BoundsCenter = default reopened at the type what the commit closed at
the seam. Dropping the default alone would NOT have closed the review's own
scenario (a copied Cylinder call site would write Vector3.Zero explicitly
and stay green), so ShadowShape's constructor is now private and BSP shapes
are built only through ShadowShape.Bsp(..., FlatCollisionSphere localBounds),
which takes radius and centre as ONE value and scales them together. There
is no expression a caller can write that carries one and drops the other.
22 construction sites converted; the same sabotage now reddens 5 Core tests
where the review's sabotage A reached 4, because both BSP producers share
one scaling path.

A2 — #333 is real and bigger than filed, and its retail question is
answered. I disassembled CObjCell::find_obj_collisions @0x0052b750 from the
PDB-paired binary myself (check_exe_pdb.py MATCH) rather than inheriting the
claim: its only early-out is sphere_path.insert_type == INITIAL_PLACEMENT_
INSERT, then it calls FindObjCollisions on every unparented non-self shadow
object UNCONDITIONALLY. Retail has NO distance pre-filter, so acdream's
"+ movement + 2f" reach filter is an invention with no register row — filed
as AP-158, carrying the disassembly, the F_EPSILON = 0.0002 m contrast, and
the measured blast radius (118 of 477 unique installed physics-BSP GfxObjs
exceed its ~2.5 m budget, 46 exceed 5 m). Active AP rows 109 -> 110.

Recorded prominently in three places a reader will hit: TALL PROPS MAY SHOW
NO VISIBLE CHANGE UNTIL #333 LANDS, and a null result at the connected gate
is EXPECTED, not evidence against AP-156.

LOW items. R3: the comment claiming the cited evidence justified the whole
cap line is corrected, but int.MaxValue on the sorting-sphere branch stays —
capping at 1 would take Spheres[0], and retail's one sphere is
CSetup::sorting_sphere, a different DAT field; capping keeps the wrong field
AND flips the substitution under-inclusive (#98/#168 direction). AP-157
already owns it. R4: acdream scales the flood sphere where retail's
find_transit_cells never reads gfxobj_scale — added as a second residual on
AP-156. R5: retail's slack constant carried into AP-158 and #333. A3: the
per-call delegate allocation is back to a cached field, still derived from
the single bounds resolver. A5: noted; b52967de's message cannot be amended.

Gates: all 44 bin/obj deleted before every verdict-deciding build, each test
run gated on a verified "Build succeeded" in the same invocation. Release

b52967def3 fix(physics): AP-156 — flood the BSP sphere where the geometry is, not at the part origin
The AP-152 retail review (docs/research/2026-08-06-ap152-review-retail.md)
FAILED `4abd1b5e` and is right. `ShadowObjectRegistry.BuildFloodSpheres` took
each physics-BSP part's ROOT BOUNDING SPHERE RADIUS
(FlatCollisionAssetBuilder.cs:393 -> LiveEntityCollisionBuilder.cs:137) and
centred it on the PART ORIGIN (ShadowShapeBuilder.cs:194), discarding the root
sphere's own Origin.

Re-measured independently against the installed client_portal.dat, reproducing
the reviewer's numbers exactly: 376 of 973 physics-BSP parts have
|origin| > radius/2, worst 20.762 m on a 27.708 m sphere (gfx 0x010036DD,
Setup 0x0200129A). Over the 172 Setups AP-152 moved onto that path the emitted
flood FAILED TO CONTAIN the object's own BSP sphere for 170 of them (73
CylSphere-bearing, 97 Sphere-bearing), worst shortfall 9.911 m on Setup
0x02000255 — whose one part's sphere sits 9.911 m above the part origin — and
for 43 the post-AP-152 flood was strictly SMALLER than the pre-AP-152 one.
Indoor flooding is 3-D (CellTransit.cs:601 routes every id & 0xFFFF >= 0x0100
candidate through FindTransitCellsSphere), so a tall prop or door slab was
absent from EnvCells it physically occupies and therefore never a broadphase
candidate there (TransitionTypes.cs:3763 iterates only entries already in the
cell). That is the #98 / #168 class AP-152 exists to remove.

Retail, re-disassembled from the PDB-paired binary (check_exe_pdb.py MATCH,
CodeView GUID 9e847e2f-777c-4bd9-886c-22256bb87f32), every address resolved
back through named-retail/symbols.json:

  CGfxObj::physics_sphere is [gfxobj+0x74] (physics_bsp is [+0x78], as
  CPartArray::CacheHasPhysicsBSP @0x00518110 reads at 0x00518127), and
  acclient pseudo-C 0x00534b5b assigns it BSPTREE::GetSphere(physics_bsp).

  BSPTREE::GetSphere @0x005397e0
    8b01        mov eax,[ecx]     ; BSPTREE::root_node
    83c004      add eax,4         ; past BSPNODE::vfptr -> CSphere sphere
  So retail's per-part flood sphere IS the BSP root bounding sphere,
  ORIGIN INCLUDED (acclient.h: BSPNODE { vfptr; CSphere sphere; ... },
  CSphere { Vector3 center; float radius; } -> radius at +0xc).

  CPhysicsObj::find_bbox_cell_list @0x00510fc0 adds the object's own cell and
  then walks the PART ARRAY: 0x00511012 call 0x518160
  (CPartArray::calc_cross_cells_static), which dispatches [edx+0x7c] with
  (num_parts, parts, cellarray). Its EnvCell body,
  CEnvCell::find_transit_cells @0x0052cae0:
    0x0052cb31  mov edx,[eax+0x20]   ; CPhysicsPart::gfxobj (CGfxObj**)
    0x0052cb36  mov esi,[ecx+0x74]   ; physics_sphere (else +0x90 drawing)
    0x0052cb4c  add eax,0x30         ; CPhysicsPart::pos
    0x0052cb5a  call Position::localtolocal   ; transform the sphere CENTRE
    0x0052cb65  fadd [esi+0xc]       ; only NOW the radius
  Retail transforms the centre through the part's own Position before it ever
  touches the radius. Carrying the radius alone is not an approximation of
  that; it is a different sphere.

Changes:

* `ShadowShape` gains `BoundsCenter` — the bounding sphere's centre in the
  shape's own local frame, scaled like LocalPosition and Radius. Zero for
  Cylinder/Sphere shapes, whose LocalPosition already IS their centre.

* `ShadowShapeBuilder.FromSetup` gains a `physicsBspBounds` resolver that
  supplies radius AND centre from ONE call, replacing the placeholder radius
  plus a downstream substitution. `LiveEntityCollisionBuilder` now holds a
  single `Func<uint, FlatCollisionSphere?>` and derives its dispatch predicate
  from it, so the gate and the geometry cannot disagree and the radius cannot
  be taken while the origin is dropped. That split is what produced this bug;
  it no longer exists.

* `FromLandblockBspParts` carries the centre too. A landblock-baked part array
  is the same CPartArray walk, so stair runs, fences and rock clusters had the
  identical defect. Both storage forms (flat BSP and the graph fallback) are
  covered.

* `BuildFloodSpheres` places each sphere at
  partWorldPos + rotate(BoundsCenter, partWorldRot), composed exactly as the
  ShadowEntry rows are.

* The 10-sphere clamp now applies to the CYLSPHERE branch only. Retail's clamp
  is inside CObjCell::find_cell_list @0x0052b9f0
  (0x0052ba21 cmp eax,0xa / 0x0052ba28 mov ebp,0xa); the BSP walk has none and
  the sorting-sphere overload @0x0052b990 takes one sphere. 7 installed Setups
  carry more than 10 physics-BSP parts (max 49, Setup 0x02001A91) and their
  tail parts were dropped from the flood entirely. Without this the new
  containment assertion would have covered shapes production never floods
  from.

Register. AP-155 was two divergences with different code paths, populations
and gates under one id; it is NARROWED to its static-publication half and its
flood half is split out as AP-156 WITH ITS DIRECTION CORRECTED. AP-155(b)
recorded the approximation as over-inclusive — "floods MORE cells rather than
fewer, the safe direction for membership" — and that false direction was the
stated reason the residual was safe to defer. It was under-inclusive for 170
of 172. AP-156 records the correction, this fix, and the one genuine residual:
acdream's sphere-vs-portal traversal where retail walks each part's sphere
against the cell's own portal planes. AP-155(b)'s "acdream approximates
retail's bounding BOX" was wrong too — find_bbox_cell_list forms no box.
AP-157 filed for the review's F4: retail's third branch floods from ONE
CPartArray::GetSortingSphere @0x00518b00 ([partArray+0x54]+0x70 =
CSetup::sorting_sphere; 4,154 of 5,935 installed Setups carry a non-zero one)
where acdream floods from every Sphere shape, and acdream's cylinder flood
ignores CylHeight. Deliberately NOT bundled here: different branch, disjoint
population, different live gate. Active AP rows 107 -> 109, literal count.

Tests. Both flood tests the review named substituted a CONCENTRIC Radius = 14f
at LocalPosition = Zero — the one configuration in which the defect cannot
appear. Every fixture is now off-centre by default, and
`FromSetup_CylSphereAndBspSetup_FloodsTheBspFootprint` drives the production
`physicsBspBounds` seam instead of hand-substituting. Five new facts: the
flood centres on BoundsCenter not the part origin; it rotates BoundsCenter by
the part rotation; it caps cylspheres at ten but never the BSP parts; the
landblock path carries the scaled centre in both storage forms; and an
installed-DAT containment sweep asserting every emitted BSP flood sphere
contains that part's real bounding sphere at entity scale 1.75, behind four
external controls — 973 parts, 376 off-centre, 172 affected, and 170
would-fail-if-the-origin-were-discarded, the last of which fails if the
population ever stops exercising the field.

Nine sabotages, each reverted and re-verified:
  A drop BoundsCenter from the flood       -> 3 Core
  B rotate by entity rot, not part rot     -> 1 Core (the rotation fact only)
  C FromSetup discards the origin          -> 1 Core + 2 App + 1 Content
     (the shipped defect, now caught in three projects)
  D drop entScale on BoundsCenter          -> 2 App + 1 Content
  E landblock flat branch drops the centre -> 1 Core
  F landblock graph branch drops it        -> 1 Core
  G drop partScale on the landblock centre -> 1 Core
  H re-apply the 10-cap to every branch    -> 1 Core
  I remove the cylsphere cap               -> 1 Core
AP-152's own two sabotages re-run against this tree: the step-0 gate disabled
still reddens exactly its five facts with Headless 89/89 green, and
cylinder-first flooding still reddens exactly one.

Clean Release build after deleting all 44 bin/obj: 0 errors, 21 pre-existing
warnings. Complete suite 11,208 passed / 4 skipped / 0 failed, +5 on the
11,203 baseline at 4abd1b5e — Core 4264 -> 4268, Content 126 -> 127, App
unchanged (one rename, not an addition). No new skips.

NOT yet gated live. This moves shadow-cell membership for real objects, in
both directions, and the connected session must look for both: props and doors
that START blocking from a neighbouring cell (the 73 CylSphere+BSP Setups),
AND ones that STOP blocking (the 99 Sphere+BSP Setups can shrink; 43 shrink
below their pre-4abd1b5e size, which is the regression this fixes). Tall
indoor props and door slabs — the ones whose sphere sits metres above the part
origin — are where the change is largest.

4abd1b5eb7 fix(physics): AP-152 — dispatch collision shapes BSP-first, at emission and at the cell flood
The register row predicted "catching or stopping on a doorway sill". That
symptom could not have been occurring. `Transition.BspOnlyDispatch`
(TransitionTypes.cs:1348, landed 2026-05-25 as A6.P7) already skipped both
primitive branches (:3911, :3954) whenever the target's wire PhysicsState
carries HAS_PHYSICS_BSP_PS, and ACE sets that bit from CSetup.HasPhysicsBSP
for every affected Setup. The extra primitive was never tested for collision.

The live defect was CELL MEMBERSHIP. The same shape list feeds
`ShadowObjectRegistry.BuildFloodSpheres`, which had no such guard and
preferred Cylinders over everything whenever any Cylinder existed — retail's
SECOND priority applied ahead of its first. For the 73 CylSphere+BSP Setups
acdream therefore flooded shadow cells from the cylinder and never from the
slab: an object absent from cells it physically occupies, which is the
#98 / #168 symptom class, not the door-collision class the row named.

Retail, re-disassembled from the PDB-paired binary (v11.4186, CodeView GUID
9e847e2f-777c-4bd9-886c-22256bb87f32, check_exe_pdb.py MATCH) rather than

    0x005152fb  call 0x52b990        ; sorting-sphere branch, below the jump

Priority at both consumers: BSP -> CylSphere -> Sphere -> nothing. BSP wins.
Every address above was resolved back to its symbol by exact lookup in
named-retail/symbols.json.

Changes:

* `ShadowShapeBuilder.FromSetup` gains a step-0 dispatch gate. Steps 1 and 2
  are skipped entirely when any part's EFFECTIVE GfxObj carries a physics
  BSP. The gate and step 3 now share one `EffectivePartGfxObjId` helper, so
  they cannot read different identities — a gate on `setup.Parts` would,
  after an ObjDesc swap, suppress the primitives while step 3 emitted
  nothing and `Build` returned null, deleting the entity's collision.
  Emission order is unchanged. This also removes acdream's undeclared
  reliance on the server sending the flag: the gate is derived from the
  parts, exactly as CPartArray::CacheHasPhysicsBSP @0x00518110 derives it.

* `ShadowObjectRegistry.BuildFloodSpheres` now applies calc_cross_cells'
  own order: BSP, else Cylinder, else everything. Given the gate above this
  is a no-op for every shape list acdream produces (FromSetup is now
  exclusive; both landblock-static publishers already emit homogeneous
  lists), so the measured membership delta remains attributable to the
  gate alone. It is kept for the same reason BspOnlyDispatch is kept: retail
  genuinely dispatches here, and it guards a future additive producer.

`Transition.BspOnlyDispatch` is deliberately untouched.

Register: AP-152 RETIRED with its four false statements corrected — the risk
statement (the symptom was already inert); "small and centred at the part
origin" (max primitive is 6.714 m, and 0x0200086E's sphere origin is
(0.759, 0.165, 5.842)); the cottage door's "~14 cm base Sphere" (it is
0.100 m; 0.141 is Setup.Radius, which AP-22 proved is never collision
geometry); and naming one pinning test where two existed. AP-153/154/155
filed: retail's dispatch flag is cached once at InitPartArrayObject+0x7e
where acdream's gate is live; the query-time guard takes a client-derived
flag off the wire; and the static publishers emit Setup Spheres as
height-capped Cylinders while BuildFloodSpheres approximates retail's
bounding box with bounding spheres.

Tests. Both pinning tests corrected, neither deleted:
`FromSetup_DoorSetup_ProducesFourShapes` -> `..._EmitsBspPartsOnly`;
`FromSetup_DoorSetup_SphereAtExpectedLocalOffset` re-hosted on
`_ => false`, the DAT-real configuration for the 3,605 Sphere-only Setups.
`FromSetup_ScaleFactor_MultipliesAllRadiiAndOffsets` was the campaign's
eighth green test covering nothing — its assertions sat inside
`if (CollisionType == Cylinder)` on a fixture with zero CylSpheres, so only
`Scale == 2.0f` ever ran. Proved empirically: with the sphere radius scale
deleted, the old body passes and the corrected body fails. Three new facts:
the effective-identity gate, the App-layer CylSphere+BSP registration (no
App fixture combined the two before), and the flood-set dispatch. One new
installed-DAT sweep pins 172 affected Setups (73 CylSphere+BSP, 99
Sphere+BSP) behind external bucket controls, re-measured independently and
agreeing exactly with the filing commit's separate sweep.

All eight sabotages run and reported; every discriminating fact reddens in
the intended direction and only there. Clean Release build after deleting
every bin/obj: 0 errors. Complete suite 11,203 passed / 4 skipped / 0
failed, +5 on the 11,198 baseline at ec29a732 — exactly the five added
facts, no new skips.

Blast radius, corrected: the FromSetup half is graphical-only (its sole
production caller is LiveEntityCollisionBuilder in AcDream.App, which
AcDream.Headless cannot reference — Headless -> Runtime -> Core/Content).
The BuildFloodSpheres half lives in AcDream.Core and DOES execute in
Headless via LandblockPhysicsContentBuilder, but is behaviour-neutral there
because both of that builder's registrations pass homogeneous lists.
Headless suite green at 89/89.

NOT yet gated live: this changes shadow-cell membership for 22 Setups used
by 151 Door weenies and 38 stationary props. Needs a connected session.

7b3e2895cd docs: close the AD-10 review findings — AD-65's magnitude was half the truth
Both AD-10 review lenses PASS; the deletion stands. These are the findings
they raised. One production file touched, comment-only.

AD-65 WAS UNDERSTATED BY HALF, and it is the finding that matters. The row
states the factor as cos^2(theta) and then quantified 1-cos(theta): "13% at
30 degrees, 29% at 45". The correct figures are 25% and 50%. This is not
algebra alone — #331's probe in the same push measures 0.0735 m travelled for
a 0.1 m request at 30.96 degrees, i.e. 26.5% short, which is exactly
cos^2(30.96). AD-65 is a LEAD for #269's slope-slide residual; at the
understated magnitude it reads as marginal and could have been dismissed. At
50% short at 45 degrees it is a serious candidate. I repeated the wrong figure
in conversation before the review caught it.

"VERBATIM/FAITHFUL PORT" of Transition.AdjustOffset was asserted in five
places and was false as of the very next commit, which filed AD-65 and AD-66
against that same function. Corrected to "structurally exact, with exactly two
filed divergences" in the register row and the production doc comment.

RECORDED, and it favours the change: the redundancy measurement is CONTINGENT
on AD-65 — the two mechanisms agree today partly because both under-travel
downhill. That makes this deletion a PREREQUISITE for fixing AD-65 rather than
merely compatible with it; had the projection survived, correcting
AdjustOffset would have re-introduced a disagreement between two live
projections. The record claimed no such thing and should have.

UNTESTED AXIS recorded: the contract's T2 — its mandatory wrong-plane-versus-
right-plane discriminator — was dropped without record, breaching the
contract's own clause requiring exactly that to be written down. The
consequence is precise: the deletion is measured, but the change's only
claimed BENEFIT (a walkable non-terrain surface now gets the committed contact
plane instead of terrain far below) has zero automated coverage and rests on
source reasoning. Stated in the row rather than left implied.

#331 SEVERITY RAISED from UNKNOWN — the discriminator is known and it is not
the fixture. With `body: null` the same uphill sweep climbs (ok=True, moved
(0, -0.0999, +0.060)); with a body supplied it returns ok=False and zero
movement, under a call profile identical to the local player's
(IsPlayer|EdgeSlide + the human two-sphere Setup). A diagonal request keeps
cross-slope X and zeroes only up-slope Y, and it fires on a 1.1 degree ramp.
So "confined to the synthetic fixture" is no longer the comfortable default:
the failing call shape is the shape production uses. Nothing in the suite
asserts uphill progress on a walkable slope, which is why it was invisible —
the test that found it passed vacuously, because the body never moved.

Also: malformed XML doc on ComposeOffset (duplicate </summary> swallowed the
retirement note from tooling) fixed; the placement-cutover plan's item 5 and
its stale "After C5" line now record AP-22 and AD-10 as retired.

Core builds clean.

886333a2a9 refactor(physics): delete the redundant pre-sweep slope projection (AD-10 retired)
Stage 0's measurement (previous commit) says the projection is redundant,
so AD-10 retires by deletion rather than by narrowing.

The measurement. With the sample forced to null at BOTH fork sites, from a
clean build:

  * a remote running 30 ticks down a 31-degree walkable ramp produces a
    BIT-IDENTICAL trajectory, position for position;
  * on an 8.4-degree ramp the two differ by at most 2.8e-5 m in Z after 30
    ticks (0.03 mm) and are identical in X and Y — float ordering noise
    from projecting twice against the same plane rather than once;
  * the whole AcDream.Runtime.Tests suite is unchanged.

That is what redundancy looks like, and the arithmetic explains it. The
boundary projection and Transition.AdjustOffset are the same operation
(v -= N * dot(v, N)) against the same plane, and the composition is
idempotent: a vector already on the plane has dot(v, N) == 0, so the
sweep's own projection is a no-op on an already-projected offset and the
full-strength projection on an unprojected one. Either alone produces the
same offset. On terrain a THIRD mechanism, ValidateWalkable's push-out,
re-seats the sphere on the plane every sub-step regardless.

Deleted:
  * both RuntimeRemotePhysicsUpdater sample sites (the host and no-host
    fork branches carried the block verbatim — the AP-22 shape, a row
    naming one site where two exist);
  * the terrainNormal parameter and projection block on
    RemoteMotionCombiner.ComposeOffset;
  * the same block on ComputeOffset, which has no production callers but
    held a second copy of the divergence, so leaving it would have made
    the row's retirement false;
  * PhysicsEngine.SampleTerrainNormal, now callerless.

Removing the parameter rather than passing null is deliberate: it is what
makes a future one-site-only regression a compile error instead of a
silent half-fix.

Two tests went with it —
ComputeOffset_RootMotionFallback_SlopedTerrainNormal_ProjectsZOntoSlope and
its flat-ground twin. Both were weak on their own terms: they drove the
production-dead ComputeOffset and computed their expected values by
re-implementing the projection formula, so they could catch a wrong
MULTIPLY but never a wrong PLANE — which is exactly what the divergence
was. The surviving coverage is geometric and runs the production tick.

Three claims in the old row did not survive contact with the code and are
recorded in the retired row rather than quietly dropped: the justification
(remotes do run the sweep); the description of ComposeOffset's guard as
"interpolation-active" when the code reads `if (!interpolationOverwrote`;
and the roof clause, stale since Bug B gated the sample on OnWalkable —
a steep roof is OnWalkable == false, so the path never ran on #32's
geometry. The retail anchor is corrected too: pc:272296-272346 truncated
both the sliding-normal validity gate at the head and the entire safety
push-out block at the tail. The whole function is 0x0050a370,
pc:272271-272393.

This does not fix #32 and does not partially fix it. #32's remote half was
already closed at 204d0ae0. What deletion does improve is the case #32
never covered: a remote on a WALKABLE non-terrain surface — a bridge, a
dock, a gentle roof, a ramp inside a building — where the terrain sample
returned the plane of the ground far below and applied a wrong plane
rather than none. That surface now gets the body's own committed contact
plane, because that is the only projection left.

The planning contract this work executed is committed alongside as
docs/research/2026-08-06-ad10-contract.md.

Release build 0 errors. Complete solution suite 11,196 passed / 4 skipped
/ 0 failed against the ef976c6d baseline of 11,195 / 4 / 0 — reconciled
exactly as +3 new Runtime tests and -2 deleted Core tests.

Visual gate outstanding: G1 (the ~5 Hz staircase on rolling terrain) is
the veto criterion and runs first; then slope-descent smoothness, a
walkable non-terrain surface, the #32 roof scenario, and flat ground.

bc4679cda5 fix(physics): delete the invented Setup-radius collision cylinder (AP-22)
Retail synthesizes NO shape for a shapeless object, so the fix is deletion,
not a corrected height formula.

CPhysicsObj::FindObjCollisions @0x0050f050 dispatches exclusively -- BSP xor
CylSphere xor Sphere xor nothing. The BSP branch leaves via an unconditional
`jmp 0x50f2b0` at 0x0050f19d and cannot reach the primitive branches; a
CylSphere-bearing object that survives its loop returns rather than falling
through to the Sphere loop; and with zero cylspheres, zero spheres and no
physics BSP, `0x0050f22f je 0x50f31b` branches straight to the epilogue,
returning the OK_TS seeded at `0x0050f13b mov edi,1`. CPartArray::GetRadius
(0x005180a0) and GetHeight (0x005180b0) are absent from the function's entire
call set -- Setup.Radius/Height serve attack cones, cylinder_distance and
MoveTo, never collision geometry. Disassembled directly from the PDB-paired
binary (GUID 9e847e2f-777c-4bd9-886c-22256bb87f32) rather than read from the
Binary Ninja text, whose ebp_1 aliasing in this function is visibly corrupt.

THREE copies were deleted, not one. The AP-22 register row cited
LiveEntityCollisionBuilder.cs and ShadowShapeBuilder.cs; the latter never
reads Setup.Radius at all, and the row omitted both
LandblockPhysicsPublisher.PublishStaticEntity and
LandblockPhysicsContentBuilder.PublishStaticCollision -- the second being the
only copy the headless host executes. Fixing just the cited site would have
left headless statics on the invented footprint.

The branch was unreachable dead code, not a live approximation. A sweep of all
5,935 Setups in the installed client_portal.dat -- validated by byte
accounting (5,935/5,935 records consumed with an exact 20 + 48*numLights
residual tail, zero unexplained bytes) and independently reproduced by the
production FlatCollisionAssetBuilder.FlattenSetup path -- finds 0 Setups
satisfying the guard: every Setup with Radius > 0.0001 carries at least one
CylSphere or Sphere, and all 1,294 genuinely shapeless Setups have Radius
exactly 0. Buckets: 678 cylsphere, 3,605 sphere-only, 358 BSP-only, 1,294
shapeless, 4,282 with Radius > 0.0001. Nothing loses collision because nothing
gained it, so no visual gate is required.

Tests, all sabotage-verified in both directions:
- InstalledSetupCollisionReachabilityTests (new, Content) -- the negative
  claim plus five EXTERNAL positive controls, so a broken enumeration cannot
  satisfy it vacuously. Inverting the claim reddens it; emptying the
  enumeration fails on the controls at 0 != 5935 rather than passing.
- ShapelessSetupWithRadius_ProducesNoRegistration (new, App) -- restoring the
  deleted block reddens exactly this fact and nothing else.
- Build_PropagatesExactStateFlagsScaleAndFullSeedCell -- re-hosts the state /
  PWD-flag / seed-cell coverage that rode on the deleted fallback test, whose
  fixture (a Setup with a radius and no primitives) cannot exist in the DAT.
  Flipping a FromPwdBitfield bit reddens it; so does swapping SeedCellId for
  the landblock id.

Also corrects ShadowShapeBuilder's retail-anchor comment, which claimed each
part's find_obj_collisions tests "CylSpheres + GfxObj BSP".
CPhysicsPart::find_obj_collisions @0x0050d8d0 tests ONLY the GfxObj physics
BSP; CylSpheres are a Setup-level array reached via CPartArray::GetCylsphere.
That comment was the written justification for the additive emission now filed
as AP-152, so it is corrected here even though AP-152 is not fixed here.

AP-22 retired with evidence; AP-152 filed (live path emits primitives AND BSP
parts additively where retail is exclusive -- 172 of 5,935 Setups including
BSP doors; deliberately not folded in, it needs its own visual gate). Issue
#330 filed: the headless host registers no live-entity collision at all, a
pre-existing gap this survey established and nothing tracked.

Gates: Release build 0 errors / 0 warnings. Complete solution suite
11,195 passed / 4 skipped / 0 failed (baseline 11,193/4/0 at bcb66ccd; +1 App
for the added fact, +1 Content for the reachability test; the replaced test is
net zero). No new skips. Headless.Tests 89/89 exercises the site-3 copy.

73cdb95c7b fix(streaming): make a demoted landblock render-ready like a published one (#280 D-1)
Both #280 review lenses returned FAIL on the same defect, and both were
right. IsRenderNeighborhoodResident's widened outer arm requires
IsRenderReady out to FarRadius, justified by "a Far-tier landblock
registers with an empty mesh set and is therefore render-ready." That held
only for a landblock that ARRIVED as Far. The second, equally first-class
way to be Far tier is a Near->Far DEMOTE:

  DemoteLandblock -> EnqueueNearLayerRetirement
    -> LandblockRetirementStage.MeshReferences
    -> GpuWorldState.ReleaseLandblockMeshReferences
    -> LandblockSpawnAdapter.OnLandblockUnloaded  => WantsLoaded = false

while DetachNearLayer deliberately keeps the landblock loaded, terrain-mesh
resident, terrain-collision resident and DRAWN. Nothing re-publishes an
already-loaded landblock, so the demoted member satisfied NEITHER arm of
the gate, permanently: wormhole tunnel plus centered "In Portal Space -
Please Wait..." forever, no recovery short of relog.

Reachable by ordinary play. Two consecutive recalls to the same landblock
with walking in between makes ChangesStreamingCenter false, so there is no
origin recenter and the region recentres through the ordinary demote diff.
Also reachable via a mid-hold quality-preset drop -- ironically the exact
scenario ReconcileDestinationReservationRadius was added to support. The
pre-#280 radius-1 gate never touched that band, because nothing inside the
Near ring can demote.

FIX SHAPE. Make the two routes genuinely equivalent rather than teaching
the predicate to tolerate the difference. ReleaseLandblockMeshReferences
becomes "reconcile the registration to the post-retirement tier": after the
release converges, if the landblock is still loaded AND still Far tier,
re-assert the empty registration -- the identical OnLandblockLoaded(lb,
empty) a PublicationKind.Far activation makes. It is empty by construction:
DetachNearLayer retains only live server projections, which the adapter's
atlas-tier filter skips. A full retirement is unaffected (DetachLandblock
clears both _loaded and _tierByLandblock), and a throwing release still
retries because the re-assert is only reached after the adapter converged.

The alternative -- "|| (IsFarTier && IsLoaded)" at the gate -- was
rejected: it fixes one caller while leaving IsRenderReady meaning two
different things, which is precisely how this defect arose. After this
change the predicate reads "drawable at its current tier" for every caller,
with no knowledge of how the landblock got there.

WHY THE TESTS MISSED IT, fixed here too:

- Proof obligation P2 was discharged against RESIDENCY (the FarRadius+2
  eviction threshold) rather than against IsRenderReady, the gate's actual
  atom. The contract now carries the correction and the restated
  obligation: no transition may REVOKE IsRenderReady from a landblock that
  stays inside FarRadius.
- WorldRevealDerivedWindowIntegrationTests advertised itself as end-to-end
  against the real GpuWorldState but constructed it with no spawn adapter,
  so its IsRenderReady degenerated to IsLoaded via the "?? true". The
  single most load-bearing predicate in the change was stubbed out by a
  null in the test named after it -- the same shape as C5b's D3 and #276's
  three settler tests. Every fixture in that file now owns a real
  LandblockSpawnAdapter.
- The P1 test's comment described its subject as "a Near-shaped completion
  the streaming window has since DEMOTED to Far". It is not; it is a fresh
  PublishAsFar, the case that does hold. Corrected, since a future reader
  would have taken it as demote coverage.

Four new regression tests, all driving the real GpuWorldState +
LandblockSpawnAdapter + LandblockPresentationPipeline through an actual
demote, and all sabotage-verified in both directions (fail with the
production change reverted, pass with it):

  NearToFarDemote_LeavesTheLandblockRenderReadyThroughTheRealPipeline
  NearToFarDemote_LeavesTheLandblockRenderReadyUnderBudgetedRetirement
  TieredWindow_StaysResidentAfterAnOuterRingDemote
  OutdoorReveal_SurvivesAnOuterRingDemoteDuringTheHold

The budgeted variant exists because production composes
LandblockRetirementCoordinator.CreateBudgeted, whose MeshReferences stage
is a separate call site from the legacy pipeline's.

SECONDARY, same commit:

- R-1: ACDREAM_PROBE_REVEAL_RADIUS=0 was parser-accepted and
  Runtime-rejected -- it yields far = 0 for an outdoor destination, which
  fails invalid-readiness-shape on every acknowledgement, hanging the very
  A/B route the probe exists to measure. Parser floor raised to 1, with a
  7-case table test.
- R-2: the composite-warmup TRIGGER had silently moved onto the far
  window's critical path. Pre-#280 the gate and the composite domain were
  the same radius-1 square; #280 widened the gate without widening the
  domain, so every composite upload serialised behind the last outer-ring
  landblock for no readiness benefit. Warmup now starts once the NEAR
  sub-window is published -- trigger scope == domain scope, as before. The
  reveal gate is untouched: Evaluate still requires the full window AND
  composite readiness.
- AP-150 filed: acdream's RetailWaitCueDelay = 5 s arming is NOT retail's
  trigger, and #280's commit message got this wrong on both clauses. Retail
  emits the notice unconditionally per tunnel rotation segment, in the else
  arm of the segment-expiry test at 0x004D6FCD; segment duration is
  RandDouble(0.6, 1.8) s, byte-decoded at 0x004D6FE6. The 5.0 constant at
  VA 0x007991B0 is CellManager::CheckPrefetchStatus's prefetch RETRY
  cadence and has nothing to do with the cue. acdream's own 0.6/1.8 segment
  constants already match retail exactly; only the arming is wrong.
  Adopting retail's unconditional emit is filed as #329 rather than folded
  in here -- it is a user-visible presentation change and wants the user's
  eyes.
- AP-151 filed: the gate is materially STRICTER than retail on the
  mesh-build/GPU-upload axis. Retail's LScape::PreFetchCells blocks on DAT
  RESIDENCY only -- no geometry construction, no upload; that work is lazy
  at draw. acdream requires a DAT read, terrain mesh build, render-thread
  upload, spatial commit, collision admission and spawn-adapter activation
  per member of a 625-member window, metered at MaxCompletionsPerFrame.
  Nothing bounds the hold. This is the OPPOSITE asymmetry from AP-149; both
  are live at once, on different axes.
- AD-2's amendment stated the false Far-tier readiness assumption verbatim;
  corrected, along with the same error in
  claude-memory/reference_two_tier_streaming.md, which now carries an
  explicit DO-NOT-RETRY on the special-case-the-predicate shape.
- AP-115 scope-noted (it covers the cue's presentation, not its arming).
- #326's SmartBox::set_mid_radius citation corrected: the entry is
  0x00453180; 0x004531D0 is the mid-function re-arm branch.

Blast radius: GpuWorldState, LandblockSpawnAdapter,
WorldRevealReadinessBarrier and StreamingDiagnostics are all App-internal;
AcDream.Headless and AcDream.Runtime reference none of them outside
comments. Headless tests run green as part of the gate below, per C5b's
lesson about surveys that skip the no-window host.

Gates: Release build 0 errors, 18 pre-existing xUnit analyzer warnings.
Complete suite "dotnet test AcDream.slnx -c Release -m:1" with
ACDREAM_PAK_PATH set: 11,192 passed / 4 skipped / 0 failed, from a clean
rebuild (a prior session's deleted probe file had been compiled into a
stale test DLL). Baseline at fafc0b65 was 11,179 / 4 / 0; the +13 delta
reconciles exactly to this commit's additions -- 3 readiness tests, 1
integration test, 7 parser table cases, 2 warmup-trigger tests. None of the
known flakes #302/#308/#321 surfaced, and none is conflated with the
finding above.

fafc0b65d9 fix(physics): adopt the settle's resolved cell across an indoor seam (#276 remainder)
SpawnPlacementSettler committed settle.Position but discarded settle.CellId,
so a compressed first-gravity-frame settle that crossed a cell boundary left
the body's cell at the placement cell until some later resolve corrected it.
Now committed through the same guarded channel the per-tick resolve writeback
uses (RuntimeOrdinaryPhysicsUpdater): resolved cell when the transition
reports one, source cell otherwise, never a zeroed residency.

Retail anchor: CPhysicsObj::SetPositionInternal(CTransition const*)
0x00515330 commits both sphere_path.curr_pos.objcell_id and its frame,
including EnvCells.

WHERE THE DEFECT ACTUALLY BIT — #276's own framing is half wrong, and the
half it misses is the whole fix. PhysicsBody.Position's setter already
mirrors the world delta into the landblock-local frame and lets
LandDefs.AdjustToOutside recompute the 24 m cell index from it, so an
outdoor->outdoor settle already landed the right cell and dropping
settle.CellId cost nothing there. It cannot do that for an EnvCell: an
EnvCell id is not derivable from a position, so the mirror deliberately
PRESERVES it. settle.CellId is therefore the only carrier of a cell identity
across an indoor seam. The live defect is the issue's parenthetical
("outdoor/EnvCell seam, stacked EnvCells"), not its main clause — and the
change is consequently a no-op on the outdoor path that dominates
production, corrective only at the seam.

That finding is what made the test possible. The three existing settler
tests build bodies with NO CellPosition and pass identically with or without
this change — shipping against them would have repeated C5b finding D3, a
test that passed with its own change reverted. The new test seeds an EnvCell
id over plain outdoor terrain instead, so the stale-id preservation is the
discriminator and no EnvCell geometry fixture is needed.

Sabotage-verified: restoring `body.Position = settle.Position` fails exactly
the new test (1 failed / 4) and leaves the other three green — confirming
both that the new test discriminates and that the old ones never could.

Core suite 4,263 passed / 1 skipped / 0 failed, +1 for the new test.

Still open and unverified, deliberately not claimed closed: whether the
remote spawn-seed caller (LiveEntityNetworkUpdateController) hands in a body
that carries a CellPosition at all. CommitTransitionPosition early-returns on
a zero cell, so this fix is an inert no-op there and #276's remote half may
survive. The C3c local first-entry caller is confirmed — it passes
activation.Body.CellPosition.ObjCellId. Scoping detail in
docs/research/2026-08-06-276-remainder-scoping.md.

3aab05b0cc fix(streaming): derive the portal reveal window from the live streaming radii (#280)
The user watched far terrain visibly assemble after portal space exits.
The reveal gate was NOT missing a hold — Slice E's hold mechanism is
correct and already in place. The hold was measuring the wrong domain:
it opened at a hardcoded 3x3 landblock neighbourhood (~192 m) while the
visible world extends to the fog end (~2,189 m at the shipped High
preset, inside a 2,304 m Far window). An 11.4:1 ratio.

Retail's equivalent ratio is 1:1 BY CONSTRUCTION. `LScape` owns one
`mid_width x mid_width` array of `CLandBlock*` (`LScape::SetMidRadius`
@0x00504C00, `LScape::update_block` @0x005063A0), `mid_radius` is
assigned directly from the user's `Render.LandscapeDrawDistance`
preference (`SmartBox::SetRegion` @0x004531F0; values
`Render_LandscapeDrawDistance_Values` @0x007CA988 = {3,5,8,11,15,25},
default 8 — both byte-verified against the PDB-paired 2013 binary), and
that same square is simultaneously the prefetched set
(`LScape::PreFetchCells` @0x00505660), the drawn set (`block_draw_list`
over the same array), and the set the simulation blocks on
(`CellManager::blocking_for_cells`). There is no retail configuration in
which the client streams farther than it gates, because there is only
one number.

So the fix derives rather than duplicates. Four coupled parts, which is
why this is one commit and not four — D1 without D2 hangs the client and
D2 without D1 is dead code:

D1 `WorldRevealReadinessBarrier` takes a live `Func<StreamingRevealWindow>`
and stops being static: outdoor requires `FarRadius`, indoor still 0
(retail's `CEnvCell::PreFetchCells` @0x0052D1E0 arm). Read per
evaluation, never captured — the radii are runtime mutable through
Settings, and retail's answer to a mid-hold radius change is to reset,
re-radius, and re-arm the blocking prefetch at the NEW value
(`SmartBox::set_mid_radius` @0x00453180). `OutdoorNeighborhoodRadius`
is deleted; there is no constant left to drift.

D2 `StreamingController.IsRenderNeighborhoodResident` becomes tiered,
because acdream's loaded landscape is: inside `NearRadius`,
`IsNearTier && IsRenderReady`; out to `FarRadius`, `IsRenderReady` only.
Without this the fix cannot work at all — nothing outside the Near ring
is ever promoted, so any radius above `NearRadius` was unsatisfiable and
would have held the reveal forever. Proof obligation P1 (a Far-tier
landblock genuinely satisfies `IsRenderReady`) is now a test driven
through the real `PublicationKind.Far` pipeline against a real
`LandblockSpawnAdapter`, not an inference.

D7 `RuntimeWorldTransitState.AcknowledgeDestinationReadiness` re-derived
`indoor ? 0 : 1` and failed `invalid-readiness-shape` on any other
value, so changing the radius alone would have looked like "the fix
hangs the client". It is now a SHAPE invariant (`indoor => 0`,
`outdoor => >= 1`). Runtime does not own the graphical host's streaming
configuration and must not learn it; plumbing App radii into Runtime to
preserve the strict equality is exactly the assert-a-mechanism-that-does-
not-exist failure C5b was built to stop. Both non-graphical producers
keep emitting their centre-ring token and stay legal, annotated in place.

D6 `PhysicsEngine.IsNeighborhoodTerrainResident` rebuilt a full-map
`HashSet` on every call, every frame of every hold. At radius 1 that was
invisible; at radius 12 (625 ring members) it violates Slice I1's
0 B/resolve standard. Now an engine-owned scratch set, cleared in place;
measured at 0 bytes over 1,000 warmed radius-12 queries.

Also: the destination reservation opens at exactly the gate's radius and
reopens on the same generation when the radius changes mid-hold (retail
has one square for both, and no concept of prioritising an inner ring
differently). Composite warmup deliberately stays `NearRadius`-scoped —
the composite domain is entity-scoped and Far builds carry no entities,
so widening it would walk the outer window to warm nothing.
`ACDREAM_PROBE_REVEAL_RADIUS` is a measurement probe in a diagnostic
owner (CLAUDE.md rule 5) so the connected route can be run A/B on one
binary; it is NOT a user-facing prefetch knob, since a low setting would
reintroduce the decoupling this slice exists to close.

Register: AD-2 amended with the derived window, the two-tier split, and
the four new retail anchors. AP-149 FILED for the residual this does not
close — the outer ring accepts terrain-only publication where retail
requires LandBlockInfo and every building EnvCell, so a distant building
can still pop in at Far-ring distances. Do not let a later closeout
claim parity.

Docs: `ACDREAM_STREAM_RADIUS`'s CLAUDE.md description was wrong on every
clause (the default is unset, not 2; it forces `NearRadius`; it is
silently discarded by any Settings save) — corrected, since that is the
file every session reads. `reference_two_tier_streaming.md` corrected in
four ways, including "Far tier = terrain only": Far also publishes
terrain COLLISION, which is precisely what makes this fix viable.
#280's issue text had the right conclusion from a wrong premise (it
names a view-distance setting acdream does not have) — corrected, and
the missing Viewing Distance option filed separately as #326, with #327
(DDD progress readout) and #328 (hardcoded 5000 f far plane vs retail's
byte-verified 4000) filed alongside.

Expect LONGER holds and the "In Portal Space - Please Wait..." cue on
recalls MORE often. That is convergence toward retail, not away from it:
retail emits the byte-identical string for the whole duration of a
blocked prefetch and polls at 5 s intervals. The failure condition is
non-convergence, not duration.

Gates: Release build 0 errors. Complete suite 11,178 passed / 4 skipped
/ 0 failed, against a re-measured 11,142 / 4 / 0 baseline at 9ee9c1a1 —
+36, reconciled exactly as 36 new tests (App +23, Runtime +10, Core +3),
zero deleted, zero newly skipped. Nine discriminating tests
sabotage-verified in both directions. The connected/visual gate is
batched into C5's matrix; its recipe, its three positive artifacts, and
its required recall leg are written into the campaign plan.

9ee9c1a1a6 fix(runtime): close the C5b re-review findings — Gate A narrowing filed, no-window payload gate, bisect hazard recorded
Both C5b re-reviews returned PASS on 02578441..ff100cf3. This lands the
bookkeeping corrections they left, the one gate asymmetry both found
independently, and one wrong retail fact neither of them caught.

1. AP-148 / #325 — Gate A's teleport test, wrong on primary source twice.

The C5b contract stated retail's Gate A teleport term as "TELEPORT_TS
equal" (and, in the trace block, as "must NOT be newer") and blessed
acdream's `teleport == _timestamps[Teleport]` as retail-exact. Disassembly
of the PDB-paired binary at SmartBox::HandleReceivedPosition
0x0045402B-0x00454054 says otherwise: the shortcut is taken iff the wire
stamp is equal OR newer (wrap-safe) — `sbb eax,eax / neg eax` materialises
the carry of the compare and the branch skips Gate A on CF, i.e. only when
the wire stamp is strictly OLDER. It is CPhysicsObj::newer_event
@0x00451B10's identical idiom with the operands swapped. Binary Ninja drops
the flag test and renders it `if (-((eax_7 - eax_7)) == 0)`, always true —
which is why two rounds of reading pseudo-C recorded it backwards.

So acdream's ForcePosition disposition is a strict SUBSET of retail's Gate
A set, and a local ForcePosition carrying a newer teleport stamp is
misrouted into a full Apply: wire heading instead of preserved heading,
unparent, possible placement frame, zeroed velocity, TELEPORT_TS advanced,
and OfferTeleportDestination called for a packet retail never starts
presentation for.

PhysicsTimestampGate.cs is NOT changed. The predicate exists twice (also
ValidAcceptedAuthority's PreviousTeleport == AcceptedTeleport), and the fix
has to decide TELEPORT_TS's disposition on a Gate A path that has never
seen a stale-but-equal pair. #325 records all of it and says explicitly
that it is not a one-line comparison swap. C5b made this marginally
better, not worse: clearParent was unconditionally true before C5b and is
unchanged; installPlacementFrame moved toward retail's HasAnims gate.

2. Retail F2 / architecture L-A — the no-window route had no pre-merge
payload validation. Root fix, not a documented asymmetry.

The graphical route validates before the merge (OnPosition's payloadIsValid
-> LiveEntityInboundAuthorityGate's !payloadIsValid return); despite its
name CanAcceptPositionPayload is not projectile-scoped. The no-window route
had no equivalent, and since D1 fed an unvalidated LandblockId into
CommitWireCellRebucket — where 0 is the withdrawal shape, silently
de-residencing the entity in the field every bot reads as CellId.

RuntimeLiveEntitySessionController.OnPositionUpdated now applies the same
rule at the same point, reusing
RuntimeAuthoritativePositionRouteClassifier.IsValidCreateWirePosition plus
the finite-velocity term — the exact pair TryApplyPosition already applies
on its initial-residence branch. Chosen over documenting it because the fix
is five lines and leaving it would have left two written claims falsified
by the code. It is a behaviour change: headless now drops packets it
merged. Against ACE the set is empty, and the graphical host has carried
this gate since it was written; the argument is recorded in the contract's
§15.2 rather than gated.

Two test fixtures carried cell ids retail's own inbound_valid_cellid
rejects (low words 0x41 and 0x51, above the 0x40 landcell ceiling). Their
constants were corrected; their assertions were not.

New test sabotage-verified in both directions: gate removed -> red at the
withdrawal-shape assertion; gate moved to guard only the cell commit ->
red at the pose assertion, which is what makes it a before-the-MERGE test
rather than a before-the-commit test.

3. Register and doc corrections.

- AD-64: "deliberately absent" was presented as the complete difference
  list and was not. Adds (a) the residence gate is weaker than the merge's
  own — both hosts' commits use TryGetCurrent while TryApplyPosition's FIFO
  branch uses TryGetTransaction, so the wire cell can commit ahead of the
  continuation that will replay it; (b) the two missile gates are two
  different expressions that agree today; (c) the payload gate, now
  present. Risk column records that (a) and (b) have no discriminating test
  on either side.
- AP-147: amended for D1 — pre-D1 the no-window host published [Updated]
  alone and lost the Rebucketed, so a headless event log is now a real
  instance of the "consumer that snapshots a delta" the row warns about.
- AD-60: "Matches retail exactly" scoped to the withhold, since the row's
  body documents two channels that do not.
- CommitWireCellRebucket: notes the unreachable ThrowIfNull /
  EnsureNotDisposed precedence inversion.
- TryCommitAcceptedWireCell: the discarded commit bool is explained rather
  than left bare — false means IsCurrent went stale, unreachable three
  statements after a synchronous TryGetActive.

4. Bisect hazard recorded in the C4 closeout handoff (the doc CLAUDE.md
sends readers to before any C5 work) and in the contract's §15.3: commits
735f0a72..23aa62f2 contain a live headless defect — every remote's
FullCellId frozen for the session — introduced by 735f0a72 and fixed only
at ff100cf3. Nothing throws and no test in the range fails.

Gates: Release build 0 errors/0 warnings. Complete suite 11,142 passed /
4 skipped / 0 failed against the 11,141 / 4 / 0 baseline — net +1, exactly
the one new test. No flake appeared (#302, #308, #321 all green).

ff100cf33f fix(runtime): give the no-window host a post-merge canonical cell commit (D1, AD-60/AD-64, AP-146/#320)
C5b (735f0a72) made the steady-state accepted-Position merge stop writing
residency. That is retail-correct — HandleReceivedPosition @0x00453FD0 reads
the wire objcell_id into a local and never assigns the object's cell — and it
stays. What C5b did not account for is that its replacement writers both live
in AcDream.App: the OnPosition prologue rebucket (AD-60's W2) and the
post-routing wire-cell adopt (W3, AP-135).

The two hosts run parallel, non-shared inbound routes. LiveEntitySessionController
-> LiveEntityNetworkUpdateController.OnPosition is graphical-only;
RuntimeLiveEntitySessionController.OnPositionUpdated is the no-window route and
is constructed only at HeadlessSessionHost.cs:682. So AcDream.Headless had NO
post-merge cell writer at all. Every remote's FullCellId was written at
create/placement and then frozen for the session — and RuntimeEntityObjectViews
.Snapshot projects exactly that field as RuntimeEntitySnapshot.CellId, i.e. every
bot's entire world view. The local player lost one of AP-146's three refresh
edges, which matters beyond cosmetics: RuntimeSetPositionState
.IsAffectedCollisionResident reads FullCellId to pick which bodies a landblock
retirement parks, so a bot running A->B without teleporting would have retired A
while parking a body physically in B.

The fix, in three parts:

1. RuntimeEntityObjectLifetime.CommitWireCellRebucket — a new Runtime owner for
   the committed VALUE, extracted verbatim from LiveEntityRuntime
   .RebucketLiveEntity. This is also the root-cause fix for the layering
   inversion the review found: AD-60 was documenting its own correctness by
   naming an App class the Runtime assembly cannot reference. Behaviour on the
   graphical side is unchanged — record.FullCellId is a proxy for
   record.Canonical.FullCellId, which is the record the callee reads, and the
   commit is still CommitRebucket. Verified load-bearing for BOTH hosts:
   sabotaging the preserve branch reddens the graphical
   LiveEntityRuntimeTests.CanonicalOnlyRebucket_DoesNotOverwriteAuthoritativeFullCell
   as well as the new headless assertion.

2. RuntimeLiveEntitySessionController.TryCommitAcceptedWireCell — the no-window
   W2, under the same reachability rules the graphical route applies: Rejected
   writes nothing (the shape the App authority gate produces by returning false);
   a bound-projectile packet writes nothing (routed by the graphical host through
   the canonical projectile placement owner, which returns before W2); an active
   initial-create residence writes nothing (RebucketLiveEntity's own early
   return — while the lease is live the SetPosition conductor is the sole cell
   authority); a local ForcePosition writes only when the accepted-Position drive
   declined it (NotApplicable), because a handled force is
   placement-receipt-authoritative. W2/W3 themselves are untouched.

3. On the committed value (the landblock-vs-cell trap). RebucketLiveEntity's
   preserve branch fires on a LANDBLOCK-shaped id — low 16 bits 0xFFFF — and
   exists for LocalPlayerProjectionController.Project, the per-frame local
   movement caller that emits exactly that shape. An inbound wire objcell_id is
   never landblock-shaped, so on the accepted-Position route the branch is not
   taken and the exact wire cell is committed. That is what W2 commits today and
   what this now commits; the no-window host has no per-frame caller at all.

Ordering is matched, not improved on: the force drive submits its placement
before the commit, so its first submit still reads the pre-commit FullCellId —
AP-138's amended route-2 CurrentCellId measurement.

Bookkeeping in this commit:
- AD-60 corrected. Its surviving-channel enumeration presented "the local force
  path, the missile arm" as exhaustive; the entire no-window host belonged in it.
  23aa62f2's W2/W3-redundancy measurement is preserved verbatim.
- AP-146 and #320 amended the same way — their three-edge list was written from
  the graphical host and silently assumed both hosts shared it. The no-window
  host had two of three; it now has all three.
- AD-64 filed: the reachability decision is now expressed once per host. The
  value is single-sourced; the gate set is not.
- #324 filed: unifying the two session controllers is the genuinely correct fix
  and is campaign-sized (presentation recovery, hydration, the equipped-child
  renderer, and the remote/projectile routing arms only one host has). Not
  attempted here, per the fix brief.

Gates. Release build 0 errors. Complete suite 11,141 passed / 4 skipped /
0 failed, against the 11,134 / 4 / 0 baseline at 23aa62f2 — net +7, exactly the
7 tests added. Eight sabotages verified, each red on at least one discriminating
test and green when reverted: remote commit removed (2 Runtime + the end-to-end
Headless test); local ordinary commit removed; local NotApplicable-force commit

23aa62f292 fix(review): close the C5b architecture-review findings (D2/D3/D4, L1-L5, S1)
Follow-up to C5b (735f0a72). The retail-conformance review passed, so no
production behaviour line moved: the flag truth table and the
refreshPosition:false withhold are untouched. This is blast radius, test
discrimination and documentation fidelity - plus two findings I could not
confirm and am rebutting rather than complying with.

D3 - THE PUBLISH-CONSERVATION TEST DID NOT DISCRIMINATE. The reviewer was
right and it was the worst finding here: proof obligation 3's test passed
identically with C5b reverted. Its only delta assertion FILTERED
(Assert.Single(deltas, Rebucketed && parentGuid)), so the pre-C5b stream
[Rebucketed] and the post-C5b stream [Updated, Rebucketed] both satisfied
it, and childSpatialBefore+1 held in both worlds because whichever site did
not move the cell propagated idempotently. It now asserts the complete
ordered parent stream plus each element's CellId and Position.ObjCellId.
Sabotage: restoring refreshPosition:acceptedPosition turns it red (it was
green before), together with the withhold test and the new L5 test.

That cardinality change was itself unfiled and is now AP-147: a
cell-changing accepted Position publishes TWO entity deltas where it
published one, and the intermediate Updated pairs the OLD CellId with the
NEW wire Position - a torn pair that did not exist pre-C5b, since both
halves used to move inside one publish. No production consumer reads a
delta's paired fields, but a recorder/plugin/bot event log would capture
it. The row states why suppressing the Updated is not available at that
layer (the merge cannot know whether its caller reaches W2).

D4 - THE PROJECTILE DOC COMMENT WAS FALSE AND ITS RETAIL ARGUMENT WAS
INVERTED. SyncPresentationFromResolvedBody claimed record.FullCellId is
"the WIRE cell ... stamped by the merge's RefreshDerivedState/SetFullCell,
before classification ever runs" and argued from retail's store_position
@0x00515CE2 that the destination cell is the right one. C5b falsified the
premise; the missile arm also returns before W2, so nothing stamps the wire
cell for a projectile at all. Rewritten. The honest conclusion, which the
old text would have called wrong: on a stored outcome presentation now
pairs the DESTINATION world position with the SOURCE cell. That is not a
choice this method can make differently - StoreAcceptedDestinationPose
writes only Position/Orientation, so record.FullCellId and
body.CellPosition.ObjCellId now hold the same source cell and reading
either yields the same value. The divergence is AP-138 item (1)'s
store-writes-pose-but-not-cell residual, retiring via #309, not a field
choice here. Projecting the wire cell instead would invent a residency the
placement declined - the AP-1 shape C5b closed.

L3/L4/L5 - PINNING GAPS, ALL THREE CONFIRMED AND CLOSED.
L3: the matrix's oracle passed HasAnimations as a literal, so the merge's
old.MotionTableId ?? old.Physics?.MotionTableId and
RuntimeAcceptedPositionRouteRequests.Build's canonical-snapshot twin were
textually identical and pinned by nothing. The oracle is now BUILT by the
production constructor.
L4: every fixture set both MotionTableId halves to the same value, so
deleting either operand of the ?? was undetectable while the production
comment said the mixed case is the real-world one. Six mixed rows added,
including the explicit-zero row (a present-but-zero top half is not null,
so ?? never reaches the physics half).
L5: the retained Rebucketed ternary had zero coverage through
TryApplyPosition - every restoreCancelledPark test called Forget directly.
Now driven through the real merge, with the wire cell deliberately the
SOURCE while the park's committed body cell is the DESTINATION, so the
restored residency can only have come from the rollback.
Sabotage (each red, each restored): merge ?? -> top half only, 1 red;
-> physics half only, 2 red; Build's ?? -> physics half only, 2 red;
ternary -> constant Updated, exactly the L5 test red.

L1/L2 - THE MISSING TEST IS ADDED; THE DEFECT IS NOT THERE. The reviewer
was right that C5b's "no fixture covers pickup at that layer" was
inaccurate - LiveEntityNetworkOnPositionCollapseMatrixTests drives the real
OnPosition at ~26 sites - and the end-to-end test is added: withdraw ->
accepted Position -> IsSpatiallyProjected && FullCellId == wireCell, both
guid classes.

But ChildUnparentDisposition.Pending is NOT a live defect, because it is
production-unreachable. The sole production _withdrawProjection binding
(LivePresentationComposition.cs:599) is
LiveEntityProjectionWithdrawalController.WithdrawExact, whose only Pending
mint is inside its catch block and therefore always carries a non-null
Failure - and AdvanceUnparentTransition rethrows at
EquippedChildRenderController.cs:1307 BEFORE the return Pending at :1309.
The named drop scenario does not reach it anyway (BeginDetachedRemoval has
already emptied the capture list) and would be correct if it did: a
previously-equipped child is LegacyImmediate, so the FullCellId != 0u gate
at DatLiveEntityProjectionMaterializer.cs:767 is never consulted and
re-projection uses the wire cell at LiveEntityRuntime.cs:824.

Measured while building that test, and NOT what C5b assumed: W2 and W3 are
REDUNDANT on the remote tail. Sabotaging W2 alone - adopting the committed
cell instead of the wire cell, OR skipping the rebucket outright - leaves
the whole file green, because W3's RemoteMotion.CellId write reads through
to canonical FullCellId via CommitCanonicalCell, whose CellCommitted
recovery re-installs the bucket. Only removing BOTH goes red, and then the
new test is the only red in the file. So it is named for what it pins, and
AD-60 is amended with the measurement: neither channel is individually
load-bearing, so a future retirement of one is caught by nothing else.

D2 - REBUTTED, WITH THE REAL GAP FILED INSTEAD. The reviewer's hypothesis
was that TryApplyInitialCreateCompletionPresentation's staleness guard lost
its ability to detect an intervening steady-state Position when C5b stopped
the merge stamping the wire cell, and asked for a PositionAuthorityVersion
term. I do not think that is right and did not add it.

The receipt's facts are the canonical BODY's pose and cell at publish
(PublishExecutorCompletion builds both from the record). Exactly two owners
can move them: a Runtime SetPosition commit/withdrawal, every one of which
calls AdvancePlacementCommit - the only caller family is
RuntimeSetPositionState - and a rebucket, which moves FullCellId. Both are
already covered by the two existing terms. An accepted steady-state
Position is neither, and C5b did not make it one: the merge refreshes the
snapshot and advances PositionAuthorityVersion but never wrote the body,
and the App generic tail writes the RENDER entity. The wire-cell half stays
covered because W2/W3 commit it in the same call; the paths that return
before them leave the record at the last committed cell, which IS the
receipt's own cell - correctly not a supersession.

Adding the term would decline receipts whose facts are still true, on the
entity's FIRST world-visible moment: the pose write and
RebucketLiveEntityPresentationOnly would be skipped while TryPublishPlace
still publishes, so a packet returning before the render write would leave
the sidecar visible at its materialized pose in a wrong bucket. That is the
handoff's own "removed the invariant failure while leaving the bug" shape.

There IS one supersession neither term covers, and it predates C5b:
RuntimeRemotePlacementDriveController.StoreAcceptedDestinationPose writes
body.Position/Orientation on the far-snap Refused/Contention arm with no
placement commit and no cell move. Filed as #323 with the FIFO-blocking
argument for why a receipt can still be pending when it lands, an explicit
"not established as reachable", and an explicit "do not fix it with
PositionAuthorityVersion". The guard's comment now carries the whole
argument instead of one sentence.

S1 - DANGLING POINTER CLOSED. InboundPhysicsStateController.cs:610 still
said the two-callers-one-rule debt was "tracked for the eventual cutover
unification ... See docs/ISSUES.md", which pointed at nothing after C5b
closed #275 without a successor. Filed #322, cited from both the comment
and #275's closure, including why widening TryApplyPosition's signature to
take a route would be the wrong unification.

AP-138 amended: C5b staled its round-3 measurement that "both
accepted-Position callers commit the accepted wire cell to
record.FullCellId before submitting". Route 2 submits from
TryExecuteAcceptedLocalPosition ahead of W2, so on a first submit
PlacementTouchesPrefix's CurrentCellId arm now names the SOURCE landblock,
not the destination. Confined to which prefix the quiescence pre-flight
matches, which that row already established is not the correctness
mechanism.

GATES. Release build 0 errors. Complete suite 11,134 passed / 4 skipped /
0 failed, from the 11,125 / 4 baseline at ed806997: net +9, all new tests,
no test deleted or weakened, no new skip. Runtime.Tests 1195 -> 1202 (+6
mixed-motion-table rows, +1 park-rollback fact); App.Tests 4132 -> 4134
(+2 guid rows). None of #302/#308/#321 appeared. Not connected-gated -
nothing here changes runtime behaviour.

735f0a72af fix(physics): classify before merge on every steady-state Position (C5b, #275, AP-131/AD-60)
The steady-state accepted-Position merge did two things retail never does,
on every single Position packet: it installed the wire placement frame and
unparented unconditionally, and it derived the record's FullCellId from
bare wire acceptance. Both are now correct, and they land together - a
half-flipped intermediate (classified flags with the wire stamp, or vice
versa) is exactly the mixed-residency state this campaign keeps paying for.

WHY the flags need no route. SmartBox::HandleReceivedPosition @0x00453FD0
decides both pre-placement writes BEFORE MoveOrTeleport is consulted: Gate A
@0x0045400C returns @0x0045409D ahead of unset_parent @0x00454129 and ahead
of the HasAnims SetPlacementFrame gate @0x00454137. Neither gate reads the
near/far/teleport classification. So the two flags are a pure function of
(disposition, hasAnimations) and are computable inside the merge, pre-merge,
with no signature change, no route construction and no playerDistance - the
scoping's ~150-400-line route-plumbing estimate over-counted because it did
not see this. That truth table IS
RuntimeAuthoritativePositionRouteClassifier.ClassifyAcceptedPosition's own
ApplyPlacementFrameBeforeRouting/UnparentBeforeRouting rows; the classifier
stays the oracle and the equality is pinned by test, not by a shared path,
so each computation remains separately sabotage-verifiable.

WHY the cell is withheld. HandleReceivedPosition reads the wire objcell_id
into a LOCAL @0x00453FE3 and hands it only to BlipPlayer / TeleportPlayer /
MoveOrTeleport / ConstrainTo; it never assigns the object's cell. The
object's cell moves inside the placement family (SetPositionInternal
@0x00515BD0 to set_cell, enter_world) or per-frame transit, and nowhere
else. The continuation executor has encoded that rule since the executor
slice; this caller now matches it verbatim.

WHAT DELIBERATELY SURVIVES. Two steady-state wire-cell writers stay,
downstream of the merge and outside the classification window: the
OnPosition prologue rebucket (W2, into CommitRebucket), which is also the
local player's own cell-freshness path, and the post-routing wire-cell adopt
for non-placing arms (W3, AP-135). Gating W2 "for symmetry" would freeze the
player's canonical cell between teleports and #319's child-cell equality
would inherit the freeze. AD-60's rewrite names both so the retirement
cannot be misread as "wire acceptance never changes residency anywhere".

REGISTER. AP-131 RETIRED - the unconditional literals no longer exist; the
caller was corrected, not deleted, so the row's own "deleted at the
production cutover" framing is overtaken. AD-60's legacy half RETIRED and
the row REWRITTEN rather than deleted, naming W2/W3 (route 4b-3's D8
precedent: a silent whole-row deletion would hide surviving channels).
AP-130 amended - the merge consumes the same static HasAnimations proxy,
deliberately not escalated to a live animation-queue read. AP-146 and #320
amended - their "accepted inbound Position (RefreshSnapshot into
RuntimeEntityRecord.cs:234)" local-player cell writer is now the generic
tail's CommitRebucket, and a ForcePosition (which returns before that tail)
is placement-receipt-authoritative. #275 closed.

HEADLINE BEHAVIOURAL DELTA, stated once: a refused or contended local
ForcePosition now leaves FullCellId at the last committed cell where the
merge used to stamp the refused packet's wire cell. Retail cannot refuse
(AD-62) and its body keeps its last placed cell, so the new shape is the
retail-reachable one.

THREE CONSUMER SITES THE CONTRACT'S BLAST-RADIUS SURVEY MISSED, all
D2-caused, all found by the suite rather than by reading, all intended
semantics rather than regressions (recorded in the contract's new section
14):
(1) DatLiveEntityProjectionMaterializer's self-projection branch reads
    FullCellId inside OnPosition's prologue recovery, ahead of W2. It now
    correctly declines to project from an unplaced wire claim; production
    installs the bucket at W2 in the same call (verified: no return between
    the recovery call and W2 is conditioned on IsSpatiallyProjected or
    FullCellId). Two hydration tests asserted the bucket at the recovery
    boundary and now drive the production W2 step - the same shape as trap
    T2, one layer up.
(2) ProjectileController.SyncPresentationFromResolvedBody writes
    ParentCellId = record.FullCellId. On a refused missile placement that is
    now the committed source cell. The MAJOR-1 invariant is unchanged and is
    now asserted as the identity it always meant rather than as a wire-cell
    constant.
(3) The merge's Rebucketed ternary does NOT become always-Updated as the
    contract predicted, and is deliberately kept: the
    Forget(restoreCancelledPark: true) above it can roll a wakeable
    lost-cell park back, and RestoreParkWithdrawal restores canonical
    residency. That is a real cell edge produced inside this method by a
    placement owner.

TEST-COUNT RECONCILIATION. Baseline measured at this HEAD by stashing the
change: Runtime.Tests 1176, App.Tests 4135 (4132 passed / 3 skipped),
solution 11,106 passed / 4 skipped - matching the recorded figure at
6921a027 exactly. Post-change: Runtime.Tests 1195, App.Tests 4135 unchanged,
solution 11,125 passed / 4 skipped / 0 failed. Net +19, entirely new Runtime
tests: 3 facts plus a 12-row matrix theory in
InboundPhysicsStateControllerTests, 1 fact plus a 2-row theory in the new
RuntimeSteadyStatePositionMergeTests, and 1 fact in
RuntimeAcceptedPositionDriveControllerTests. No test was deleted; five
existing tests were rewritten in place, never delete-only. No new skip; none
of #302/#308/#321 appeared.

SABOTAGE VERIFICATIONS (each new discriminating test, both directions;
production line broken, suite run, line restored):
  installPlacementFrame (!force && !hasAnimations) to (!force)
    5 fail: ApplyOnAnimatedEntity_NeverInstallsTheWirePlacementFrame plus
    the 4 animated non-force matrix rows.
  installPlacementFrame to false
    6 fail: ApplyOnNonAnimatedEntity_InstallsTheWirePlacementFrame,
    PositionPlacementAbsentAndPresentZeroBothApplyRetailZero plus the 4
    non-animated non-force matrix rows.
  clearParent (!force) to true
    3 fail: ForcePositionOnParentedLocalPlayer_RetainsTheParentAttachment
    plus the 2 force+parented matrix rows.
  clearParent (!force) to false
    4 fail: the 4 Apply+parented matrix rows.
  refreshPosition false to acceptedPosition
    4 fail: AcceptedPosition_WithholdsTheWireCellAtTheMergeBoundary,
    ContendedForcePosition_WritesNoResidencyAnywhere,
    ReentrantNewerPositionDuringPickupDiscardSuppressesStalePickupDelta,
    MissileFarRefused_...ParentCellIdAgreesWithCommittedCell. Confirmed a
    second time by the baseline measurement above, where the withhold test
    was the sole red.
  CommitRebucket publishes Updated instead of Rebucketed
    2 fail: both parent classes of
    CellChangingAcceptedPosition_ConservesOneRebucketAndOneChildPropagation.
  RuntimeEntityDirectory.SetFullCell drops PropagateFullCellToChildren
    2 fail: the same two rows.
T4 respected: the ForcePosition placement-frame half is inert
(appliedPlacement keeps old.PlacementId under either flag value), so the
force row's discriminating assertion is parent retention, never the frame.

NOT DONE, deliberately: the executor is still not wired into the
steady-state path (#275's alternative branch); W2/W3 are untouched; no probe
added or stripped; AP-130's proxy not escalated; no while-here unification
of the two merge callsites. No automated OnPosition-level test drives the
full pickup / drop / reproject sequence (no fixture covers pickup at that
layer); the contract's connected gate recipe item 1 is the positive evidence
for it and has NOT been run - this commit is not connected-gated.

6921a02744 refactor(physics): delete legacy PhysicsEngine.Resolve/ResolvePlacement/HasCellSurface (C5a, AP-1/AD-1)
Member-wise deletion of the three legacy resolver members named in
docs/research/2026-08-05-c5a-contract.md: PhysicsEngine.Resolve,
PhysicsEngine.HasCellSurface, and PhysicsEngine.ResolvePlacement. An
exhaustive receiver census over src/ found zero production callers of any
of the three — every production placement writer already reaches the
canonical PhysicsEngine.SetPosition transaction exclusively through
RuntimeSetPositionState (three call sites total). The deletion is purely
member-wise: IsSpawnCellReady and AdjustPosition, which shared the same
source region as the deleted members, are preserved byte-identical — every
remaining production caller of either (including PhysicsCameraCollisionProbe,
AdjustPosition's sole surviving production caller) is unaffected.

Companion changes:
- PlayerMovementController's 3-argument SetPosition test overload is renamed
  to SeedPlacementForTest (internal) and CommitPreparedPosition is deleted;
  83 call sites across 19 test files were mechanically renamed to match.
- Seven pinned test dispositions from the contract are executed:
  3.1 (PhysicsEngineTests.cs: 11 legacy-resolver tests deleted, 6
  ResolveWithTransition tests kept), 3.2/3.3/3.4 (re-point to canonical
  SetPosition, with TransitionScratchDifferentialTests.cs additionally
  gaining positive IsCommitted assertions after each bitwise comparison so
  the differential proves a placement actually committed, not just that two
  possibly-uncommitted results match), 3.5 (Runtime rename), and 3.6
  (PlayerMovementPlacementTransactionTests.cs rewritten — its xmldoc now
  states plainly that the render-root publish moved to
  RuntimeSetPositionState.cs, but the sticky-release relocation claim was
  false and is retracted; this disposition's coverage loss is the sticky
  release path, not silently absorbed elsewhere).
- Stale `PhysicsEngine.Resolve`/`Resolve` doc citations in CellTransit.cs,
  PlayerMovementController.cs, and HeadlessSessionWorldProjection.cs are
  corrected to name the surviving canonical entry points by symbol
  (SetPosition, AdjustSetPosition/AdjustPosition, ResolveWithTransition)
  rather than fragile line numbers.

Retires AP-1 and AD-1 in docs/architecture/retail-divergence-register.md:
both rows described production zero-delta placement routing remaining on
the legacy resolver pending the Slice 4B2/4B route cutover; that resolver
no longer exists, so the condition each row tracked is now structurally
false rather than merely narrowed. AP-145 (routed through the prior commit)
and this commit's AP-1/AD-1 together bring the section counts to 101 AP / 47
AD active rows.

Builds on the AP-145 fix (previous commit) — this commit's staged tree was
independently rebuilt and its four suites independently rerun on top of
that commit before this commit was created, in addition to the combined
rebuild/rerun below.

Full-solution build: 0 errors (21 pre-existing warnings, all unrelated).
Suite results (combined tree): Core 4270/4271 passed (1 skip; the single
DatSoundCacheTests concurrent-decode-dedup failure is a known load-sensitive
race, confirmed passing standalone and unrelated to this change), Runtime
1176/1176, Headless 86/86, App 4132/4135 (3 skips).

f8e55ba5e4 fix(physics): route local-player shadow presentation through SyncPose (#318, AP-145)
RuntimePlacementPresentationSink.TryPublishPlace previously published the
local player's collision-shadow pose with a direct LocalPlayerShadowState.Set
call — a plain cache write that never touched PhysicsEngine.ShadowObjects.
Because LocalPlayerShadowSynchronizer.SyncPose's own dedup check compares
against that same cache, the direct write could pre-seed the cache with the
destination pose and cause the next real SyncPose call to see "nothing
changed" and skip its own ShadowObjects publish — leaving the real collision
shadow at the pre-teleport position until an unrelated movement tick forced
a real publish.

Fix: TryPublishPlace now calls _localPlayerShadowSync.SyncPose(...,
force: true), the same publisher ordinary per-tick movement uses, so Place
always drives a real ShadowObjects write before the cache updates.
TryPublishWithdrawal carried the exact mirror asymmetry (a bare
LocalPlayerShadowState.Clear with no ShadowObjects.Suspend, leaving a live
phantom shadow row at the park's source cell for the whole park window — the
#184 shape) and is fixed in the same commit, same one-call shape:
_localPlayerShadowSync.Suspend(entity). The sink no longer holds a direct
LocalPlayerShadowState reference; both halves route exclusively through the
one synchronizer, which owns the cache internally.

The single LocalPlayerShadowSynchronizer instance is now constructed in
LivePresentationComposition (before the sink) and threaded through
LivePresentationResult to SessionPlayerComposition, which no longer builds
its own — this guarantees the sink's Place/Withdraw edge and ordinary
per-tick movement publish through the exact same publisher and cache rather
than two independent instances that could drift out of sync with each other.

TryPublishPlace's xmldoc now states the behavioural nuance directly: routing
through SyncPose means Place inherits SyncPose's own admission guard
(IsHidden, cellId == 0, not-current-visible-projection), which the old
direct .Set() call never consulted. Under those conditions SyncPose now
calls Suspend instead of publishing — correct and symmetric, but new
behaviour worth flagging at the call site, not just in a test comment.

RuntimePlacementShadowCompositionTests.cs (#318) proves four facts against
the real ShadowObjects registry, not the cache: a bare Place publishes a
real row at the destination cell with the source cell's row gone; a
subsequent ordinary per-tick Sync is then a correct no-op; a Place for a
registered non-local-player entity leaves its row at the source cell
untouched and never touches the player's cache (route 7 P4 — the fix lives
entirely inside the pre-existing player-only gate); and Withdraw suspends
the real registry row, not just the cache, with the retained
(suspendable) registration surviving for a later restore. All four were
sabotage-verified in both directions.

RuntimeForcePositionRenderCommitTests.cs (B2) drives a real end-to-end
accepted ForcePosition through RuntimeEntityObjectLifetime.TryApplyPosition
and RuntimeAcceptedPositionDriveController.TryExecuteAcceptedLocalPosition
against a live HostFixture, asserting both the committed render position
AND a cell change that deliberately crosses out of the spawn's outdoor grid
cell, so the cell assertion is independently falsifiable rather than riding
along with the position assertion.

Retires AP-145 (this fix) in docs/architecture/retail-divergence-register.md.
AP-1 and AD-1 are untouched by this commit — they retire separately in the
deletion-sweep commit that follows.

Evidence chain: docs/research/2026-08-05-c5a-contract.md (the governing C5a
slice contract), docs/research/2026-08-05-c5a-architecture-review.md (round
1, FAIL — three MAJORs: vacuous route-7 P4 test, unfixed Withdraw-side
mirror asymmetry, non-driving B2 test), docs/research/2026-08-05-c5a-architecture-review-round2.md
(round 2, PASS with two MINORs — an unfalsifiable B2 cell assertion and the
undocumented SyncPose guard nuance, both fixed here).
