#312 (cancelled park restored Runtime state but never the presentation half)
CLOSED at b1f914d5; the two-client gate passed — the recalled remote appears in
world and on radar and stays correct after going idle, which is the specific
shape that failed (a moving remote self-heals via the per-packet prologue
rebucket; only one that parks on its final Position and then goes idle sticks).
#32's remote half closed at 204d0ae0; a remote observed in acdream now slides
down a steep face under gravity instead of freezing and then blipping. Left
open and named rather than absorbed: the LeaveGround chatter bound, the !Ok
airborne latch, the contact_allows_move action-animation watch item, the AP-140
follow-up (point the two routing gates at Body.InContact rather than
re-deriving Airborne), and local-player edge-slide, which this work did not
touch.

Regression from 7f1c1f5a (C4 route 4b-2). A remote player who recalled in,
arrived, and stood still was permanently absent from the world render AND the
radar while remaining fully simulated — 71 healthy physics ticks with contact
and walkable, interpolation enqueues, equipment attached, chat visible.
Route 4b-2 is the first commit that lets an ordinary remote UpdatePosition open
a canonical SetPosition. A park publishes a synchronous Withdraw that tears down
presentation registrations; only TryPublishPlace restores them.
RestoreParkWithdrawal — added in the same slice — restores InWorld, the object
clock, and canonical residency, i.e. the Runtime half only. Eight Opus reviews
verified those three fields and the tests asserted exactly them, so the suite
stayed green while the entity was invisible.
Why it is intermittent: the presentation half IS restored incidentally by the
per-packet prologue rebucket for a MOVING remote. It only sticks when the
entity parks on its FINAL accepted Position and then goes idle, because ACE
stops broadcasting for a stationary entity, so no later packet arrives to
re-publish it and nothing else re-drives.
The fix publishes a RuntimePlacementProjectionKind.WithdrawalRestored receipt on
the one ordered placement stream, acknowledge-only in Runtime (the parked
operation is already retired by CancelCoreDeferred), which the App sink maps to
the exact inverse of its own TryPublishWithdrawal: the projection half (bucket,
IsSpatiallyProjected, IsSpatiallyVisible, spatial indexes, RefreshPresentation)
plus the publish half (_worldState, _worldEvents, _effectPoses,
_localPlayerShadow, visibility sinks). Applied with commitPose: false, because
the withdrawal never moved the sidecar; a test feeds a deliberately wrong
position to pin that.
Two alternatives were refuted on measurement, not preference. Routing the
restore's SetFullCell through CommitCanonicalCell cannot fire on the shipped
remote path at all — the prologue rebucket has already recommitted a non-zero
FullCellId before the merge cancels the park, so no cell edge remains — and it
never touches the publish half regardless. Extending RestoreParkWithdrawal
directly reduces to the same receipt, since Runtime must not reach behind the
host sink.
Gated on the entity ending the rollback canonically whole (FullCellId != 0 &&
InWorld) rather than on residencyRestored, which is false on the shipped remote
path and would have made the fix a no-op. AP-136's quiescing-prefix refusal arm
is preserved: no receipt, entity stays withdrawn.
Corrects my own framing of the defect: _worldState/_worldEvents/_effectPoses are
lost but are NOT what kills render and radar (_worldState is the plugin
IGameState; _effectPoses is the pose registry, not entity.MeshRefs). The
load-bearing casualties are the visibility sinks and the
IsSpatiallyProjected/IsSpatiallyVisible + bucket removal that gates the radar.
Register: AD-63 filed (selection deliberately not restored — user intent),
AP-136 amended (its "restored visible" claim covered only the canonical half;
the gap was a defect, not a divergence). ShadowObjectRegistry.Suspend stays
out of scope per AP-136.
Seven-revert discrimination table including one that proves the test is not
merely re-checking the bucket. Suite 11,023 passed / 4 skipped / 0 failed.
Live gate is user-run and folds into #309: two clients, ACDREAM_PROBE_PARK=1,
recall a remote in and let it stand still; acceptance is
[park-restore] ... presentation=True for that guid plus a visible model and a
radar blip.

A remote observed in acdream landed on a sloped roof and froze; the server slid
on, the gap passed AP-87's 4 m threshold, and the body snapped — the visible
blip. Live probe capture, two adjacent ticks 63 ms apart:
t=88420671 rsInContact=True rsOnWalkable=False rsIsOnGround=True
bodyCpNz=0.6097 floorZ=0.6642 steep=True gravity=True
vel=(2.146,2.264,-3.549)
t=88420734 contact=True onWalkable=True <- forced against the sweep
gravity=False <- cleared
velBeforeZero=(2.146,2.264,0.000)
moved=0.0000 <- and every tick after
The roof is 52.4 degrees against a 48.4 degree limit, so acdream's classifier
was CORRECT and was then overruled. Four independent links each froze the body
on their own: a per-tick force of Contact|OnWalkable, a per-tick velocity zero,
a Gravity clear at landing, and a landing edge testing IsOnGround
(= inContact || ...) instead of OnWalkable. The tick called
HandleAllCollisions alone — the tail of SetPositionInternal without its prefix.
Retail simulates remotes locally and derives these bits rather than asserting
them: CPhysics::UseTime @0x00509950 iterates the whole object table;
update_object @0x00515D10 gates only on parent/cell/FROZEN with no
is_player fork; SetPositionInternal @0x00515330 sets CONTACT from
contact_plane_valid @0x00515430 and ON_WALKABLE from contact_plane.N.z vs
floor_z @0x00515465-@0x0051548E before handle_all_collisions @0x005154FE;
set_on_walkable @0x00511310 fires HitGround @0x00511364 / LeaveGround
@0x00511346 edge-triggered with no ownership gate; calc_acceleration
@0x00510950 zeroes only when CONTACT && ON_WALKABLE && !Sledding @0x0051096B;
calc_friction @0x0050EE70 returns at its first line when ON_WALKABLE is clear.
acdream had copied retail's airborne no-op WITHOUT retail's local simulation.
The fix is mostly deletion: stop forging the transients, stop discarding the
authoritative velocity, stop clearing Gravity, and route the remote tick
through the same SetPositionInternal commit TickHidden and the local player
already use, with the landing edge derived from the sweep's own OnWalkable.
AP-87's threshold and conditions and InterpolationManager's node_fail_counter
snap-to-tail are deliberately untouched — this removes the CAUSE of the
divergence rather than weakening the backstop.
Cross-checked against ACE: its only creature-side VectorUpdate emitters are the
jump broadcast and spell projectiles, so integrating the wire velocity cannot
double-move a walking remote; and PhysicsGlobals.DefaultState already carries
Gravity, so deleting the manufactured State |= Gravity is safe.
Register: AP-81 narrowed (its GRAVITY half retired outright), AP-87 annotated,
AP-139 filed (the interpolation-queue clear on the landing edge), AP-140 filed
(the two routing gates select snap-vs-interpolate on walkability where retail
uses CONTACT — adjust_offset @0x00555D30 gates on transient_state & 1
@0x00555D52). AP-140's follow-up is deliberately shaped as "point the two gates
at Body.InContact", NOT "re-derive Airborne", which would perturb five writers
and collide with a pinned RemoteTeleportPlacementTests assertion.
Three gaps recorded in #32 rather than papered over: the new LeaveGround
dispatch is untested for chatter; a persistently !Ok transition can latch a
remote airborne; and — the visual-gate watch item — the deleted forge was a
blanket guarantee of Contact|OnWalkable, and contact_allows_move @0x00528dd0
silently refuses action animations without both, which is the literal root
cause of closed#270. Retail-correct on a steep face, a regression anywhere
else.
10 discriminating tests over a real PhysicsEngine landblock whose contact
normal Z is 0.61 against FloorZ 0.6642 — the live roof's exact relationship.

Flips the SetPositionSimple classification (contact, PlayerDistance >= 96 m) for
remotes onto 4b-1's drive controller and deletes both legacy far blocks, both
duplicated 96f/4f constant pairs, and both `?? Vector3.Zero` fabrications. The
4 m constant now exists exactly once. Teleport and cell-less stay legacy for
4b-3.
Retail: MoveOrTeleport @0x00516330's far branch runs StopInterpolating
@0x005163CB before SetPositionSimple @0x005163D9 and returns 1 @0x005163E8
regardless — the SetPositionError is discarded — so HandleReceivedPosition arms
ConstrainTo @0x00454272 post-move on commit AND on failure. The x87 parity
decode at @0x00516393-@0x0051639E puts exactly 96.0 on the far branch.
SetPositionSimple @0x005162B0 builds flags 0x1012 at @0x005162C4.
Non-commit outcomes still advance the body, because retail's SetPositionInternal
@0x00515BD0 commits the destination via store_position @0x00515CE2 when no cell
resolves. The partition is by STAGE, not heuristic, enforced by an exhaustive
switch: Refused/Contention/NotApplicable/RejectedPreparation store (the placement
never executed); Committed/Deferred/RejectedByPlacement do not (the engine ran
and refused, matching retail's non-storing returns @0x00515CB2 and @0x00515CD5).
Without this a refused far snap froze the remote with an emptied queue.
Also fixes a shipped defect this route made live: ParkDeferred's quiescence parks
withdrew the entity (InWorld=false, clock suspended, residency removed) and were
never restorable, while Forget(restoreCancelledPark: true) runs for every
accepted Position on every entity. The restorable decision now lives inside
ParkDeferred AFTER SnapToCell, reading body.CellPosition.ObjCellId — the value
RestoreParkWithdrawal actually restores at — against every live quiescence
rather than one minimum-OperationId token. The three pre-snap fields are hoisted
into locals because SnapToCell ends with InWorld = true. ParkCollisionResidents
passes restorableOnCancel: false explicitly; the plain unplaceable park is
provably unchanged. RestoreParkWithdrawal re-tests the prefix at restore time so
a retained route-2 park cannot re-admit into a prefix that began quiescing
during the park.
CanAttemptDestination is retained as an OPTIMISATION only, with the two Core
predicates it cannot reproduce written down at the pre-flight, plus the two
properties that depend on it staying there.
Four fix rounds and eight Opus reviews. The slice was fully green at 10,990,
10,997 and 11,004 while containing real defects — a frozen remote pinned as
correct by its own test, a fallback that over-wrote on the exact retail paths
that decline to store, and a park guard incomplete on two independent axes.
Register: AP-137 (leftover classifications take AP-87's catch-up; states the
cell-less enqueue-vs-place delta deferred to 4b-3, that RejectedData is applied
anyway, and the headless divergence), AP-138 (the refusable far placement),
AP-136 narrowed to match the relocation. #309's acceptance steps rewritten —
step 5 previously asserted a recovery the code does not perform — and gated on a
new ACDREAM_PROBE_PARK=1 signal so the check cannot pass while broken.
Suite 11,009 passed / 4 skipped / 0 failed against a measured 10,968 baseline.
The 10,973 figure recorded earlier was wrong and is corrected here.
Connected gate outstanding: the two-client far-snap walk and #309.

Shipped-code defect affecting committed route-2 code, found while reviewing
route 4b-1.
RuntimeSetPositionState.ParkDeferred withdraws an entity from the world:
body.InWorld = false, TransientStateFlags.Active cleared, WithdrawCanonical,
SuspendObjectClock. CancelCoreDeferred then removed the operation and rewrote
the pending Withdraw into a Discard while restoring NONE of it. So cancelling a
wakeable park was strictly worse than keeping one — the park is wakeable, the
cancel destroys the only object that could ever wake it, and the entity is left
invisible AND intangible with nothing to bring it back.
Route 2's re-issue funnel masked this: re-issuing is correct for a one-shot
ForcePosition ACE never repeats, and wrong for a repeated remote stream, so the
hole was hidden rather than fixed.
Retail's own answer is a working park, verified in the decomp rather than
assumed: CPhysicsObj::SetPositionInternal @0x00515BD0, when AdjustPosition
yields no cell @0x00515C1D, calls prepare_to_leave_visibility @0x00515CDA,
store_position @0x00515CE2 (the DESTINATION pose is committed), GotoLostCell
@0x00515CF2 registering at m_position.objcell_id read AFTER store_position (so
the destination cell), clears transient 0x80 @0x00515CF7, and returns OK
@0x00515D07. InitObjCell @0x00508260 drains the lost list on cell load and calls
reenter_visibility @0x00516250, which re-places from the object's OWN
m_position with flags 0x11.
Two corrections to the direction I gave, both forced by evidence and both right:
The pose must NOT be rolled back — only the withdrawal. Three shipped route-2
tests capture positionAtPark AFTER the park and assert it survives the cancel,
and retail agrees: store_position commits the destination and nothing
un-commits it. Restoring residency at the body's committed cell is therefore
retail's own cell choice, not merely self-consistent.
The gate defaults to FALSE with four explicit opt-ins, rather than defaulting
true with opt-outs at the withdrawal callers. That keeps every one of the ~20
shipped Forget/ForgetExactPlacement sites at exactly its current behaviour
instead of depending on having correctly enumerated the withdrawal transactions.
Review had already found the broad version corrupting five of them
(TryApplyPickup, CommitAcceptedParent, CommitAcceptedParentCellless,
CommitWithdrawal, CommitPositionChannelUpdate): they hand-roll a partial
re-withdrawal that undoes the clock and FullCellId but not InWorld or the
_spatialRoots re-registration, leaving a picked-up item both in inventory and an
InWorld cellless spatial root in the physics workset.
ParkDeferred's restorableOnCancel is opt-in for exactly one of its four callers
— the plain unplaceable-destination park. Every quiescence and retirement park
is excluded deliberately: those entities are withdrawn because their world is
going away, and restoring residency inside a quiescing prefix blocks its
retirement.
VerifyPositionChannelCancellation now asserts InWorld and IsSpatialRoot per
channel — Position is a cancellation and must restore; Pickup and Parent are
withdrawals and must not. It previously asserted only !IsDeferred and counts,
which is why five green states hid this.
Register row AP-136 measured against GotoLostCell/reenter_visibility rather than
labelled "retail-shaped". Files #309 (the restore-on-cancel residual, with
park-survives recorded as the retail-faithful target and its two blockers named:
the NewerPositionPickupAndParentEachCancelExactLostOperation invariant and
teardown convergence) and #310 (an unbounded retirement stall — a retained
preparation retry pins its prefix through HasOldPrefixPlacementDebt forever, and
TickLostCellDeadlines has no production caller so the 25 s timer never fires).
This is a user-observable change to shipped paths: restorableOnCancel: true sits
in SubmitPreparedPlacementCore, the shared core behind every production
placement. AP-136 and #309 carry the proposed two-client check.
Gates: complete Release solution 10,973 passed / 4 skipped / 0 failed (baseline
10,938). Every new test discrimination-verified by reverting the fix.

The user live-tested route 4a and reported two defects on player remotes: a
remote holds the falling animation after landing before finally landing, and a
remote jumping onto a house plants on the roof where retail slides off, then
blips to the slid-down position.
Neither is a route 4a regression. Do NOT revert 44830a0e — reverting would
restore the per-packet render slam 4a removed without touching either defect.
Bug B's root cause is identified and already covered by open issue #32, whose
text names both symptoms in one sentence. Both landing sites assert
TransientState |= Contact | OnWalkable unconditionally, where retail derives it
from the contact plane — CPhysicsObj::SetPositionInternal @0x00515330
(`if (contact_plane.N.z < floor_z) set_on_walkable(0) else set_on_walkable(1)`).
A steep roof is contact but NOT on_walkable; asserting both suppresses the slide
response, so the body sits until the server's positions walk 4 m away and
AP-87's threshold snaps it. That is the blip. Verified byte-identical pre-4a via
`git show 19d95094:`.
Bug B's *visible shape* IS 4a's: pre-4a every packet slammed the render entity
to the wire pose, so a stuck body flickered toward the true sliding position
5-10x per second — jitter rather than a clean hold.
Bug A stops at the goal's stop-condition rather than getting a speculative fix.
Three hypotheses with non-overlapping fixes; picking wrong means changing a
retail-ported gate on a guess. Retail's mechanism is already fully decoded, so
what is missing is OUR runtime state — no cdb trace against retail is needed.
Adds ACDREAM_PROBE_REMOTE_LANDING (PhysicsDiagnostics, read once at startup per
the diagnostic-owner rule, one bool check when off). It logs both landing sites
immediately before HitGround, and — the most diagnostic signal — emits a
separate line when a site is reached but the gravity gate is about to no-op,
which is hypothesis 1 (a wholesale Body.State write wiping the transient Gravity
bit mid-air, exactly AP-81's stated risk). Temporary instrumentation, marked for
stripping once the evidence is in.
Evidence recorded rather than new bugs filed: #32 gains the observation, the
root cause and the #173/AD-10 dependency caveat; AP-87 gains a live instance of
its stated risk; AD-10's stale file:line is corrected to RemoteMotionCombiner
with a note that its terrain-only normal cannot see a house roof at all.
Also files #308 — a SECOND flaky test, distinct from #302, which was twice
misattributed to it before being written down. #302 is a GC-allocation assertion
in App.Tests; #308 is a wall-clock deadline loop in Core.Net.Tests that fails
only under full-suite CPU contention (0 failures in 4 isolated runs). Conflating
them hides one, and an agent told to "ignore the known flake" would wave through
a real transport regression.

Shipped defect in route 2 (9966b531), found while reviewing route 4a.
`InboundPhysicsStateController.TryApplyPosition` built its AcceptedPhysicsTimestamps
via `Current(gate, teleportAdvanced: ...)`, omitting `previousTeleport`, which
defaulted to a literal 0. The only site that populated it was the deferred
initial-create path — which is why the continuation executor was correct and
every newer consumer was not.
Consequence in shipped code: route 2 feeds this into
`ValidAcceptedAuthority`, which requires Previous == Accepted for a
ForcePosition. Any local player whose TELEPORT_TS is nonzero — anyone who has
portalled or recalled this session — had the authority rejected and the force
correction SILENTLY DROPPED. The user's @pklite acceptance was genuine but
narrow: that character had not teleported, so the stamp was still 0.
Second latent consequence: with an accepted stamp >= 0x8000, wrap-safe
TeleportRegressed also fires against the 0 and rejects ordinary Apply positions,
not just ForcePosition.
The fix captures `previousTeleport = gate.TeleportTimestamp` BEFORE
`TryAcceptPositionEvent` mutates it, matching the shape the deferred path
already used. Ordering is the whole point: capturing after would make
Previous == Accepted unconditionally, so ValidAcceptedAuthority's check would
pass vacuously — the symptom would disappear while the semantics broke.
Also removes the footgun that allowed it. `Current`'s parameter is now
`ushort? previousTeleport = null` resolving to `gate.TeleportTimestamp`, so the
eleven non-Position channels — none of which can move TELEPORT_TS — get
"previous == current" by omission rather than a literal 0 that is
indistinguishable from a genuine "never teleported".
Consumer audit: only TryApplyPosition was defective. The two route-2 call sites
trace back to it; the RuntimeEntityObjectLifetime sites source from
TryAcceptDeferredPosition and were already correct.
Tests discrimination-verified by reverting the argument to 0: the stamp test
fails Expected 10 / Actual 0, and the classifier test fails Expected
SetPositionSimple / Actual RejectedAuthority — the shipped defect reproduced
exactly.

User saw "[System] WeenieError 0x0504" on login after a PK Lite reversion.
0x0504 is YouAreNonPKAgain; only ~56 of 378 codes had strings, so the raw hex
fallback fired.
Retail's source is ClientCommunicationSystem::HandleFailureEvent @0x00571990 —
a switch with per-case literal UTF-16 strings, not a DAT string-table lookup, so
hardcoding them is retail-faithful.
The decomp could not be trusted for the text. Its dump of data_7d32c0 declares
[0x5f] and shows 95 characters ending mid-word at "...protection of the Lig".
The real string is 139 characters. The 0x5f is Binary Ninja's PREVIEW
TRUNCATION LENGTH, not the array size — worth remembering for the rest of the
switch, since a copy-paste from the dump would have shipped a truncated
sentence. Recovered by PE byte read (VA 0x007D32C0 -> RVA -> .rdata file
offset), cross-confirmed against the raw hex the pseudo-C carries immediately
after the preview.
Mapped 0x0504, 0x0505, 0x04EC, 0x04ED, each byte-verified and cited with its
case address. Retail's trailing newline is dropped deliberately (documented
in-comment): acdream renders one ChatEntry per system message where retail has a
single scrolling buffer. Adjacent codes are deliberately left unmapped with a
test pinning that 0x04EE still falls back to hex — a wrong message is worse than
a raw code.
Files #306 for the full port, with three findings that make it more than a
string table: the switch is SIX compiler-lowered blocks spanning 339 distinct
case values from 0x17 to 0x593, not one contiguous band; retail passes a colour
argument with three values in use (0 x162, 0x1a x113, 7 x59) and acdream's chat
has no colour concept; and HandleFailureEvent aborts an in-progress automatic
attack on 0x43/0x3f7/0x3e/0x23/0x36 — verified against the decomp, with the
nuance that 0x43 has no display case at all and is abort-only, so that one is a
pure gameplay gap.

The user confirmed melee and bow now work against a PKLite player in a live
two-client session ("melee and bow works, all good"). That accepts #298
directly, and #297 indirectly but conclusively: the both-PKLite arm of
ObjectIsAttackable cannot pass unless the LOCAL player's own PKLite bit is
live, which is exactly what #297 fixed.
Not separately confirmed by the user and therefore NOT recorded as accepted:
the collision-after-equip case (#297's round-2 defect) and combat-camera
tracking (#298's second site). Both are implemented, suite-green and
review-passed; they remain unverified by observation.

Marks #297 (9b1e6fc6), #298 (bc0077a5) and #299 (88348f67) DONE per the
issue-tracking rule, and adds a handoff covering what landed, what still needs
the user's eyes, and the route 4 decision waiting on them.
Three items are implemented and suite-green but NOT user-verified: collision
with PKLite players (including the equip/unequip case round 1 got wrong),
melee/bow on a PKLite player plus the auto-target guard, and combat-camera
tracking of a PKLite opponent.

Selecting a PKLite player and attacking did nothing: with auto-target on it
retargeted to the nearest monster, with auto-target off it logged
"combat: attack ignored; no creature target found". Spells on the same target
worked, which was the clue.
Root cause: CombatTargetPolicy.IsHostileMonster:31-33 rejects any candidate
carrying BfPlayer BEFORE reaching ObjectIsAttackable, so the both-PKLite pool
match at SelectedObjectHealthPolicy.cs:70-71 was unreachable for players. Melee
and missile targeting never supported player targets at all — the gate is named
IsHostileMonster and does exactly what it says. Nobody could hit it until
69ba9486 made PK Lite reachable.
Retail uses ONE predicate for monsters and players, with no player exclusion:
ClientCombatSystem::ExecuteAttack @0x0056BB70 gates unconditionally on
ObjectIsAttackable @0x0056A600 (creature type, Free-PK short-circuit on either
side, then IsPlayer -> bothPK || bothPKLite, else BF_ATTACKABLE with pets
excluded). acdream already ported that predicate verbatim; it was simply
unreachable.
The fix SPLITS the two concerns rather than relaxing the shared predicate:
explicit-target admission routes through ObjectIsAttackable, while auto-target
ACQUISITION keeps the monster-only gate. That is required by register row
IA-19 — explicit product direction that Auto Target must never select NPCs,
players or pets. IA-19 is not overridden here; its own justification promises
"manual player-selection commands remain available", and that promise was never
implemented, so this makes the row true. Review confirmed no path lets
auto-acquisition select a player: every automatic Select is fed by a
FindClosest* filtered through IsHostileMonster.
Review also found a second site with the same bug, which the first pass froze in
place on my instruction: retail gates combat-camera tracking on the SAME
predicate as the attack. ClientCombatSystem::UpdateTargetTracking @0x0056A950
reads GetAttackTarget() then gates CameraSet::TrackTarget on ObjectIsAttackable.
Ours used the monster-only gate, so with ViewCombatTarget on by default the
attack would land while the camera refused to track the opponent — user-visible
in exactly the duel this fix enables. GetCombatCameraTargetPoint now uses the
wide predicate. IA-19 does not reach the camera: it performs no acquisition,
only presentation on an already-chosen target. The first pass had added a
source comment asserting IA-19 covered it; that comment and the matching text in
docs/ISSUES.md are corrected, since a wrong citation is how a real divergence
becomes invisible.
Depends on 9b1e6fc6 (#297): the both-PKLite arm needs the LOCAL player's own bit
to be live. Review confirmed both admission sites read ClientObjectTable on every
call, so this is not inert in production.
Newly reachable and now pinned: ObjectIsAttackable's pet-exclusion arm, which
CombatTargetPolicy rejected before it could ever run.
Follow-ups filed: #304 (SelectionInteractionController.GetSelectedOrClosestCombatTarget
has no production caller — one of the two widened call sites is dead code),
#305 (HeadlessGameplayOperations has the identical pre-existing bug, so the
graphical/headless hosts now diverge).
Gates: complete Release solution 10,904 passed / 4 skipped / 0 failed (baseline
10,900). Adversarial + retail-conformance review PASS after one FAIL round; the
predicate was re-verified branch-for-branch against 0x0056A600 since it goes
live here for the first time. Camera fix discrimination-verified by revert.
Connected acceptance NOT run — needs a live two-client PKLite session.

The user typed @pklite and then walked straight through other PKLite players.
Root cause: ClientObject.PublicWeenieBitfield was written exactly once, from the
0xF745 CreateObject parse, and never refreshed. ACE's only PK-change message is
PropertyInt.PlayerKillerStatus (134) over 0x02CE/0x02CD, which we parsed and
stored into Properties.Ints[134] but never translated back into the bitfield —
and ACE never re-sends a PublicWeenieDesc at all (EnqueueBroadcastUpdateObject
has zero live callers), so that property is the ONLY signal a client can learn
from. Both sides of the collision test read the frozen value, so
CollisionExemption's "4c. both PKLite -> collide" rule could never fire.
Retail's missing port: PublicWeenieDesc::SetPlayerKillerStatus @0x005AC7C0
rewrites _bitfield in place — PK(4) -> (b & 0xfddfffff) | 0x20; PKLite(0x40) ->
(b & 0xffdfffdf) | 0x2000000; Free(0x20) -> (b & 0xfdffffdf) | 0x200000; else
b &= 0xfddfffdf. Mutually exclusive, verified byte-for-byte, with input values
confirmed against retail's own PKStatusEnum (acclient.h:6412-6427), not just
ACE's. Driven from ACCWeenieObject::OnStatUpdated @0x0058DF20 case 0x86.
The fix rewrites the value at its source rather than patching consumers. Two
review rounds were needed because the first pass missed that there are TWO
snapshot stores: InboundPhysicsStateController keeps its own private _snapshots
dictionary, and every untimestamped-field merge (ApplyAcceptedObjDesc and
friends) reads `old` from THAT store, not from RuntimeEntityRecord.Snapshot.
Refreshing only the active record left the target-side shadow flags correct
until the remote's next equip or unequip — ACE broadcasts an ObjDesc on every
one — at which point the appearance path rebuilt the registration from the
frozen spawn and dropped the bit permanently. The regression test demanded by
review is what surfaced that; it is verified discriminating (reverting gives
Actual: 8 instead of 33554440).
Five stores now hold this value, kept coherent from one source by two
ObjectUpdated subscribers plus the appearance-rebuild path. The two shadow-flag
writers are the same invalidation applied at the two edges that can invalidate
it, not competing authorities — review enumerated every drift path and closed
each. That coherence invariant is new as of this commit and is recorded as
register row AP-134, with AP-133 as the precedent for filing a row when the
danger is a future writer rather than current behaviour.
Also corrects TS-23's retirement narrative, which claimed every mover-flags call
site read the mover's "real" PK bits from 2026-07-30. The bits existed but their
source was frozen, so that only became true here; the site enumeration also
missed RuntimeSetPositionMoverPreparation, a seventh site that decodes the
snapshot directly.

The user found three symptoms live within minutes of 69ba9486 making PK Lite
reachable for the first time. Two independent root causes, neither a C4 route 2
regression (verified by diff: 9966b531 touched none of the gates, and all three
predate it).
#297 (HIGH) — PublicWeenieBitfield is written once at CreateObject and never
refreshed. ACE's only PK-change message is PropertyInt 134 over 0x02CE; we
store it but never translate it into the bitfield, and ACE never re-sends a
PWD (EnqueueBroadcastUpdateObject has zero live callers), so a client cannot
learn PK status from the bitfield after login. Both sides of the collision test
read the frozen value, so CollisionExemption's "both PKLite -> collide" rule
never fires. Retail's missing port is PublicWeenieDesc::SetPlayerKillerStatus
@0x005AC7C0, driven from ACCWeenieObject::OnStatUpdated @0x0058DF20 case 0x86.
#298 (MEDIUM-HIGH, blocked on #297) — CombatTargetPolicy.IsHostileMonster
rejects BfPlayer before reaching ObjectIsAttackable, so the PKLite pool match
we already ported correctly is unreachable for players. Retail uses ONE
predicate for monsters and players with no exclusion. Critically: the naive fix
is wrong — the same predicate backs auto-target acquisition and the combat
camera, and relaxing it would violate register row IA-19's explicit product
direction. The fix must SPLIT explicit-target admission from auto-acquisition,
which is what IA-19's own unimplemented promise already describes.
#299 (LOW) — CollisionExemption checks only the target's IsImpenetrable while
retail short-circuits on mover OR target, and the class doc asserts the
opposite. Found during the investigation; not symptom-causing.

A local-player ForcePosition had TWO independent writers for one accepted
packet: LocalForcePositionTransaction snapped the physics body
(PlayerMovementController.BlipPosition, a raw SnapToCell with no collision
resolve), while LiveEntityNetworkUpdateController's generic tail separately
wrote position/cell/rotation to the render WorldEntity from the raw wire and
rebucketed it. Two stores, one packet — the divergence class 670f307c fixed on
the remote path. The outbound AutonomousPosition ack also fired BEFORE any
canonical commit existed: we told ACE "got it, I'm here" before deciding where
"here" was, and the trailing isCurrent() could only suppress the continuation,
never recall the packet.
RuntimeAcceptedPositionDriveController is now the one Runtime-owned seam. Both
hosts call the identical TryExecuteAcceptedLocalPosition; App and headless
project the committed result through the existing placement projection sink
(LiveEntityRuntime.TryApplyRuntimePlacementPlace already performed the same
four writes, from committed state rather than a wire guess).
Retail: SmartBox::HandleReceivedPosition @0x00453FD0's FORCE_POSITION branch is
get_heading -> Frame::set_heading -> SmartBox::BlipPlayer @0x00453940 -> stamp
POSITION_TS -> SendPositionEvent @0x00454091 -> return @0x0045409D. BlipPlayer
is CPhysicsObj::SetPositionSimple @0x005162B0 with flags 0x1012
(Teleport|Slide|SendPositionEvent) — a real collision-resolving SetPosition,
not a snap. The pinned classifier already encoded this exactly.
Named behaviour changes:
* The ack is now an OUTPUT of the committed route, fired strictly after the
canonical commit and exactly once per accepted force packet.
* The ForcePosition route no longer re-arms the constraint leash. The force
branch returns at 0x0045409D, ahead of all three ConstrainTo sites
(0x00454272, 0x0045418A, 0x004541EC); the old re-arm cited retail's "Player,
normal" branch, which BlipPlayer is not on. The teleport, CommitPreparedPosition
and first-entry callers legitimately still constrain and are untouched.
* A force correction that terminates WITHOUT committing still sends its
position event and is not retried — retail's BlipPlayer discards
SetPositionSimple's SetPositionError return and acks unconditionally.
A single _pending funnel owns the in-flight placement, deciding on the token's
PositionAuthorityVersion against the record's: equal -> clear; advanced with the
newest accepted event still a force -> re-issue, re-classified; advanced to an
ordinary Apply -> clear, since newer server truth owns that pose. This closes a
double-apply/double-ack and a silently-dropped correction that two earlier
iterations of this slice each introduced.
AD-62 records the residual: a ForcePosition our async collision publication
cannot carry to a committed placement is not re-applied. Retail has no park —
its world is fully resident and its placement synchronous — so the state is
unreachable there. AP-131 is NOT retired; its legacy Position caller is route 4.
Deleted: LocalForcePositionTransaction, PlayerMovementController.BlipPosition,
HeadlessSessionWorldProjection.BlipLocalPlayer.
Gates: complete Release solution 10,858 passed / 4 skipped / 0 failed (baseline
10,844/4/0). Two independent Opus reviews (retail-conformance and
architecture/adversarial) PASS on the final diff after three FAIL rounds; every
intermediate state was fully green, so the suite caught none of the four real
defects. Connected acceptance is NOT run: nothing a user can do makes ACE emit
a ForcePosition without retail's @pklite, which acdream does not implement — see
docs/research/2026-08-03-c4-route-2-visual-gate.md.

Closes#283 (plan S3) - as UNREACHABLE, not by restructuring ownership.
acdream has two owners that convert a landblock-local network origin into the
streamed world frame: LiveWorldOriginState for presentation/streaming, and
RuntimePhysicsState.TryGetWorldFrameOffset for placement. They rebase on
different edges - Runtime the instant an accepted Position carries
TeleportAdvanced, App only once StreamingOriginRecenterCoordinator observes
old-window retirement completion, many frames later. A one-landblock
disagreement places an entity 192 m from the geometry around it: the same
failure family as the zero-offset bug 670f307c fixed, with a wrong origin
instead of a missing one.
The plan's first step was to prove or disprove reachability BEFORE moving
ownership, because a restructure on a hypothesis is churn. The probe added in
898ff18b answered it: a connected Release session recorded ZERO disagreements
across 11 completed reveals and six destination landblocks (0x0904, 0x1134,
0x3032, 0x8763, 0xA9B4, 0xF682) spanning roughly 45 km. A gap of even one
frame would have printed an offset in the tens of thousands of metres.
Cause of the safety: BeginOriginRecenter detaches EVERY resident landblock
before the new origin is adopted, so the two rebases are serialized and no
conversion can observe the gap. Ownership is therefore left exactly as it is.
What lands instead is the invariant that keeps it true.
LiveWorldOriginState.EnsureAgreesWithRuntimeFrame is checked at the
landblock->world conversion and is terminal on disagreement, converting a
silent 192 m-multiple misplacement into a loud failure with the offset in
metres and the landblock being projected. Six focused tests pin it, including
the cross-world portal case (0x09 -> 0xF6 = 45,504 m). Disagreement can no
longer reach the probe, so ACDREAM_PROBE_WORLD_FRAME now emits a verbose
per-conversion agreement trace - useful when a placement looks displaced for
some reason OTHER than a frame disagreement.
Complete Release solution: 10,844 passed / 4 skipped / 0 failed.

Connected Release session against the local ACE with the retail UI
(ACDREAM_RETAIL_UI=1). User verdict on the S1/S2 gate: works fine - effects
stay attached to moving entities across cell boundaries, and lit statics are
unchanged (the deliberately-preserved case).
The session log corroborates it: 9 completed world reveals including portals,
58 reveal events all failures=0, zero unhandled exceptions, zero parked
placements, zero firings of #284's new terminal world-frame invariant, and a
graceful exit.
#282 and #284 are closed. #283 (Runtime's world frame and App's render origin
rebasing at different moments during a teleport) remains open and is
deliberately sequenced immediately before C4 route 3, which shares its portal
code; its first step proves or disproves reachability before anything is
restructured.

Fixes#282 (plan S2). Adds register row AP-133.
Retail gives a CPhysicsObj exactly ONE cell: ShouldDrawParticles @0x0050fe60
reads this->cell and calls IsInView on it, and set_cell_id @0x0050f4f0 /
change_cell @0x00513390 are the only things that move it. acdream splits that
into ParentCellId (render parent, deliberately null for outdoor dat stabs) and
EffectCellId (the authored landcell those parentless stabs still need) - an
adaptation, now recorded as AP-133.
WorldEntity.EffectCellId documents itself as the stab field, with live and
interior entities using ParentCellId. f24532ad began writing it for live
entities too. Because EntityEffectPoseRegistry resolved EffectCellId FIRST,
that write won - and the audit shows only 3 of 14 cell writers maintain it.
The other 11 do not, including the hottest paths: RemotePhysicsUpdater:239,294
and LiveEntityOrdinaryPhysicsUpdater:107 write ParentCellId every physics tick
from the snapshot, and LocalPlayerProjectionController:79 writes the local
player's cell every frame.
So a moving entity updated its cell constantly while EffectCellId stayed
frozen at whatever cell it materialized in. Its particles and lights kept
being tested against that stale cell and failed IsInView the moment it crossed
a boundary - effects vanishing on a monster that is plainly visible, or
drawing through a wall from a room the viewer cannot see.
The consumers had also drifted into disagreeing: EntityEffectPoseRegistry
preferred EffectCellId while WbDrawDispatcher.TryGetEntityCell and the remote
spawn seed preferred ParentCellId - two answers to "which cell is this in".
- WorldEntity.VisibilityCellId (ParentCellId ?? EffectCellId) is the single
accessor; all five consumer sites resolve through it, so the precedence
cannot drift apart again.
- LiveEntityRuntime's three live-entity EffectCellId writes are removed,
restoring the field to its documented purpose. Its real writers -
LandblockLoader:80,97 and LandblockBuildFactory:408 - are untouched, and the
parentless-stab path is pinned by a new test.
- f24532ad's actual fix is preserved: RebucketLiveEntity still installs the
committed cell, just on the one field live entities use.
LiveEntityLightControllerTests.Refresh_FollowsCurrentTopLevelRootAndCell is
back to moving the entity by ParentCellId alone - its original pre-f24532ad
form - and passes. CanonicalOnlyRebucket_DoesNotOverwriteAuthoritativeFullCell
had its two EffectCellId assertions (added by f24532ad, encoding the defect)
replaced with the corrected contract: ParentCellId set, EffectCellId null,
VisibilityCellId resolving - a stronger assertion, not a relaxed one.
Complete Release solution: 10,836 passed / 4 skipped / 0 failed.
User visual check still outstanding: a monster with an active spell effect
crossing a cell boundary, and a lit static object, indoors and outdoors.

Fixes#284 (plan S1).
A first-entry placement that could not be prepared returned
RetrySetupUnavailable and was re-Advanced every pump forever. Nothing counted
it, nothing named its cause, and nothing distinguished "waiting for something
that will arrive" from "waiting for something that never can". That is why
#281's 43 test failures presented as four unrelated symptoms across App and
Runtime instead of one cause, and why a stuck entity in the live client simply
never appears with no log line to follow.
Worse, the two causes were conflated: 670f307c's missing-world-frame park
reported itself as RetrySetupUnavailable, sending anyone diagnosing it to the
prepared-asset pipeline rather than to the absent local-player Create that
actually publishes the frame.
- RetryWorldFrameUnavailable splits the two causes. Call sites now ask
IsRetryable() instead of comparing against one reason, so a future retry
reason cannot be silently reclassified as a hard rejection - the exact way
this class of bug hides.
- The operation retains its RuntimeSetPositionParkReason, and
RuntimeSetPositionOwnershipSnapshot reports parked work by cause
(ParkedAwaitingSetupCollisionCount / ParkedAwaitingWorldFrameCount /
ParkedPlacementCount), so parked placements appear wherever ledgers are
already asserted.
- ObserveLocalPlayerCreate records the accepted local-player Create even when
it carries no landblock - precisely the case where no frame is ever
published - and ThrowIfWorldFrameUnreachable makes that contradiction
terminal. Waiting is legitimate only while that Create is outstanding; after
it, no later pump can supply the frame. Same shape as 01f4791e, which made a
violated receipt-ledger invariant terminal rather than resumable.
This is observability plus fail-fast. There is no timeout, no retry cap, and
no grace period anywhere in it; retryable work still retries exactly as before
and no placement behaviour changed.
The parked counts are deliberately NOT folded into IsConverged: #277 documents
a far Create legitimately parking for a whole session, so a parked entry at
teardown is not automatically a defect. Wiring them into the connected gates
is carried with #277's service-window conversion, where "legitimately parked"
becomes definable.
Runtime 1,012/1,012. Complete Release solution: 10,834 passed / 4 skipped /
0 failed.

Three defects introduced by the 2026-08-02/03 stabilization batch, all found
while reconciling #281's 43 test failures. Each is an instance of the weakness
the placement campaign exists to remove - two owners of one fact with no single
writer keeping them agreed - so they are cleared before C4 stacks six more
placement routes on top of them.
#282: WorldEntity.EffectCellId documents itself as existing only for outdoor
dat stabs, whose null render parent still needs retail's outdoor landcell for
CObjCell::IsInView gating; live/interior entities were explicitly meant to use
ParentCellId. f24532ad began populating it for live entities, and because
EntityEffectPoseRegistry.UpdateRoot resolves EffectCellId ?? ParentCellId it
now wins - while 12+ sites still write ParentCellId alone. Retail carries one
cell per object (CPhysicsObj::set_cell_id @0x0050f4f0, change_cell @0x00513390,
ShouldDrawParticles @0x0050fe60).
#283: 670f307c gave Runtime a world frame that rebases on the accepted teleport
Position, while App's LiveWorldOriginState rebases only after old-window
retirement completes. Between those edges the two disagree by the landblock
delta. Not yet proven reachable; the plan proves or disproves it before
restructuring anything.
#284: a placement that cannot resolve returns RetrySetupUnavailable forever
with nothing counting it or naming its reason. The fix is observability plus
fail-fast on contradictory states, never a retry cap or timeout.
Plan sequences S1 (#284) first so the other two are observable rather than
archaeological, then S2 (#282), then S3 (#283) immediately before C4 route 3,
which shares its portal code. Also records the gating change that would have
caught all of this: the complete Release suite must be green before every
commit, not a focused subset.

f24532ad changed two presentation contracts that these fixtures still
expressed in their pre-change shape. Both failures date exactly to that
commit; they are independent of the world-frame family fixed in 6dcb94ac.
LiveEntityLightControllerTests.Refresh_FollowsCurrentTopLevelRootAndCell moved
the entity by writing ParentCellId alone. f24532ad now populates EffectCellId
at materialization and keeps it synchronized on canonical rebuckets
(LiveEntityRuntime.RebucketLiveEntity:845-856), because retail's
CPhysicsObj::set_cell changes the one CObjCell that ShouldDrawParticles reads.
EntityEffectPoseRegistry.UpdateRoot:163 resolves EffectCellId ?? ParentCellId,
so a production cell move writes both together and the old single-field move
left effects and lights on the stale materialization cell.
LiveEntityAnimationSchedulerTests.RetainedProjectileWithRemote_WhenMissileClears_TransfersMovementToRemoteOnce
seeded its shared remote body by assigning Position directly. Projectile
classification now validates and adopts the canonical body's own cell frame
(ProjectileController:184-190 - body.CellPosition.ObjCellId /
.Frame.Origin) rather than deriving it from the sidecar's FullCellId and the
streaming center, since a residence-managed Create legitimately still reports
FullCellId 0. A Runtime-committed body always carries its (cell, local) frame,
so the fixture now seeds it through the same SnapToCell placement API; leaving
it cell-less was correctly refused.
Both fixtures keep their original assertions - only the modelled world state
moved to match what production now commits.
Complete Release solution: 10,831 passed / 4 skipped / 0 failed

C3c created graphical effect, projectile, and static-animation sidecars before Runtime finished the entity's first SetPosition. One-shot F754/F755 packets could be discarded, projectiles could adopt a cell-less body, and animated statics could compete for body ownership. Keep effects behind an exact-incarnation presentation barrier, retry projectile/static binding on the committed visibility edge, and keep effect cells synchronized with canonical rebuckets. User verified spell, recall, arrow, projectile, portal, and static presentation; 90 focused App tests and the Release build pass.

Synchronize the architecture doc, milestones, roadmap, and ISSUES with the
continuation-executor behavior commit (5db3de3c): the residence system is
now a complete dormant mechanism, both independent reviews PASS, and the
next boundary is the all-host production cutover. The admission handoff
gains its superseded banner; the successor handoff records the executor's

The [MT-FAIL] probe caught combat-stance monsters constantly failing to
dispatch 0x40000015 (Falling): their bodies were airborne-flagged while
standing. contact_allows_move (0x00528dd0) requires Contact+OnWalkable
and silently refuses every action animation for an airborne mover - a
spawned-standing monster's swings never played until it first moved.
Retail never has this state: CreateObject spawns run the placement
transition (CPhysicsObj::SetPosition -> SetPositionInternal 0x00515330),
which establishes CONTACT/ON_WALKABLE from the floor at spawn. Our
remote creation seeded a raw position with no placement.
SeedRemoteSpawnPlacement mirrors RemoteTeleportPlacement: engine
placement resolve (Setup-derived cylinder, TS-46) + the verbatim
CommitSetPositionTransition, wired at BOTH RemoteMotion creation sites
(UM-triggered creation - so a first-ever-UM attack animates in the same
packet - and ordinary first-UP creation). Unplaceable results leave the
body airborne exactly like a failed retail placement.
Also adds the [UM-ACT] (wire action items + stamp-gate verdict) and
[MT-FAIL] (refused animation dispatches) probes, riding
ACDREAM_DUMP_MOTION=1, which are what convicted the body state.

Retail calls CPhysicsObj::report_exhaustion from exactly one site -
CommandInterpreter::HandleExhaustion (0x006b3c70), a notification handler
for the stamina-exhaustion EVENT. Campaign P P1 wired it to every
movement-stats application instead (every stamina regen/drain tick), and
each call re-dispatches the current movement state through the animation
sink - truncating any in-flight action animation. The diagnostic session
log shows 490 spurious casting-stance re-queues in one short session:
'sometimes stuck in spell animations' was every stamina tick that
collided with a cast gesture's play window.
The re-apply now fires only when the exhausted state (stamina == 0)
transitions, matching retail's event semantics. Stats still reach
PlayerWeenie immediately via RuntimeMovementSkillProjection.ApplyTo.
Also adds the [remote-edge] probe (rides ACDREAM_DUMP_MOTION=1): one
line per remote HitGround/LeaveGround - each such edge drains the
mover's pending action animations (retail HandleEnterWorld), the
working theory for intermittently missing monster attack swings.

Retail jump landings BOUNCE: the floor touch records both a contact plane
(grounding) AND a collision normal (collided_with_environment), and
handle_all_collisions reflects the unmodified impact velocity off it at
5% elasticity (v += -(v.n)(elasticity+1).n, DEFAULT_ELASTICITY 0.05
@0x007c6a7c). Our transition already recorded both facts; the bounce was
suppressed by the AD-25 adaptation stack in the per-tick commit: a
Velocity.Z<=0 landing gate (needed because the resolver glued ascending
movers to the ground) plus a landing Velocity.Z=0 hand-zero whose stated
purpose was making the reflect a no-op. Downhill glided instead of
bouncing, flat-ground landings had no pop, and uphill jumps flapped
between grounded/airborne against the animation machine.
Three retail mechanisms replace the stack:
- check_contact (0x0050f5b0) seeding in ResolveWithTransition: a body in
CONTACT seeds the transition's contact only while v.contactPlane.N <=
0.0002; moving away seeds the last-known plane alone (get_object_info
0x00511cc0). Ascending jumps therefore run contact-free (ballistic, no
glue) - the gate's reason-for-being is gone. The plane requirement is
strict: Contact-without-plane is unrepresentable in retail.
- SetPositionInternal-shaped commit (0x00515330, byte-read end-to-end,
velocity-sign-FREE): contact purely from the transition's contact
plane, HitGround on the airborne->walkable edge, HandleAllCollisions
with unmodified impact velocity. Whole commit gated on Ok &&
candidateMoved (retail pc:283657 skips SetPositionInternal entirely
when the candidate did not move) - a standing body's contact state is
never re-derived, which is what keeps rest bit-stable (AD-41 updated).
- Byte decodes: gate override state&0x800000=Sledding, zero branch
state&0x20000=Inelastic, reflect strictly dot<0 - our port already had
all three correct.
Settle: real landings (>=0.25 m/s) bounce and decay geometrically;
smaller impacts are consumed by retail's unconditional small-velocity
zero, so standing never micro-bounces. Re-baselines documented in place:
landing-survival pin measures decay post-settle; LiveCompare_Tick0/376
pin the new IsOnGround=false on zero-move ticks (captured true was the
retired seed echo; tick 376's captured body carries an 11.8 m/s grounded

fixture now carries the plane real grounded bodies always have. New
pins: LandingBounceSeedingTests (ascent no-seed, rest keeps contact,
strict plane, slope 5% reversal + tangential preservation, Sledding
override).

docs/ISSUES.md: #265 and #166 updated with the root cause and fix from
the prior two commits; closure of both pends the user's visual-gate
acceptance. #265 also records the confirmed-separate uphill-bounce
finding (AD-25, byte-exact retail, out of scope). #166 records that the
Campaign P visual-matrix recheck it was waiting on DID happen and found
the glide/bounce still missing even with AD-25/AP-7/AD-55/TS-4 all
landed - that negative result is what triggered the #265 capture bisect
and this fix.
docs/architecture/retail-divergence-register.md: AP-7's retirement note
corrected. The row's original claim ("no horizontal velocity to hammer")
undersold the gap - calc_friction was structurally unreachable with
meaningful data on any grounded path, not just inert on the root-motion
path. No new row filed: this change ports retail's mechanism faithfully
and does not introduce a new deviation.
docs/research/2026-07-30-265-capture-bisect.md: full "as-fixed" addendum
(new section 9) recording the implementation - the fix mechanism, fixture
results (freeze reproduced under the old model, slide+decay proven under
the new one), the downhill-direction derivation for the synthetic decay
case, the two separate mechanisms found while building the Runtime tests
(LeaveGround's edge-timing recompute, AP-77's no-sink fallback), the
uphill-bounce orthogonality proof, and final test totals.

Raw byte decode of MovementSystem::GetRunRate (0x006b0950, PDB-paired
binary): fild skill; fcom [800f]; fnstsw; test ah, 0x44; jp general —
the C2/C3 parity idiom whose 18/4 fall-through executes ONLY at
skill == 800 exactly. ACE read this as >= 800 ('max run speed?') and
Campaign P P1 inherited that misread when BN dropped the arithmetic,
flat-lining every maxed character at 4.5 (retail-true ~3.70, +21%) and
erasing the vitae differential (both 10200 and 15225 sat above 800).
The [stat-chain] live capture proved the enchant chain correct end to
end (vitae 0.67 -> eff run 10200 -> controller), isolating the formula.
General path byte-verified: (loadMod*(skill/(skill+200)*11)+4)/scaling/4.
InqMaxRunRate's skill=9999 probe gets ~3.6961, not 4.5.
Golden tests pin the 799/800/801 straddle and the maxed-skill vitae
differential; pseudocode doc §6 carries the decode plus a do-not-
reimport-ACE warning. Complete Release suite: 10,025 passed / 5 skips.

Retail CACQualities::EnchantAttribute (0x00594570), EnchantAttribute2nd
(0x00594670, already ported for #6), and EnchantSkill (0x005947b0) are the
three enchantment-composition functions the Character window's Attributes
and Skills tabs depend on. Primary attributes never reference the vitae
singleton in retail (only Attribute2nd/Skill do) — confirmed directly from
the decompiled function bodies, not assumed.
EnchantmentMath.GetMod gains requiredType/includeVitae parameters (default
to the prior behavior) so a numeric StatMod key collision across domains
(e.g. key=1 is both Strength and MaxHealth) can't leak a buff into the
wrong computation. Spellbook.GetAttributeMod/GetSkillMod and
LocalPlayerState.GetEffectiveAttribute/GetEffectiveSkill/
GetSkillVitaeModifier wire the retail chain through to the panel.
CharacterSheetProvider now reports the effective value as the main number
and CharacterSkill.CurrentLevel is no longer an alias of BaseLevel (this
also activates the previously-dead SkillValueColor buffed/debuffed row
coloring). CharacterStatController's footer-title parenthetical is cited
from gmAttributeUI::DisplaySelectionFooter_Attribute (0x0049d280) and
gmSkillUI::DisplaySelectionFooter_Trained (0x0049b860) +
SkillInfoRegion::GetVitaeModifier (0x004f0fa0): skills show up to two
segments (vitae's own contribution, then the buff-only residual), while
vitae-immune attributes show at most one; no parenthetical when the delta
is zero. The panel now refreshes on Spellbook.EnchantmentsChanged, not only
raw property/attribute updates.
Core goldens cover the user-reported 33% vitae example (303->203, "(-100)"
exactly), buff+vitae composition, and the attribute vitae-immunity finding.
Provider/controller tests cover the full row-click -> footer-title path and
live refresh. Full solution suite passes with zero failures.

Their 2026-07-05/17 'pending user visual gate' statuses are superseded by
the consolidated Campaign P matrix; automated backing since the fixes
(R6 acceptance, nine-stop soaks incl. today's PASS, P3 conformance
suites) is recorded per entry. The matrix result closes or reopens each.

Per docs/research/2026-07-30-ts4-116-oracle-plan.md, following the four
code commits that closed out TS-4 (5e2be19b), #116 shape-2 (01492205),
and AD-55 (252e8068), plus #116 shape-1's Path-6 fix (db2889af) and the
TransitionalInsert return-value fix (7e1be3de):
- ISSUES.md #116: shape-2 marked CLOSED (D4 un-skipped, structurally
confirmed, no cdb needed). Shape-1 narrowed, not closed: the Path-6
head-sphere fix is a real, independent improvement but the tick-22760
confirming replay showed it doesn't explain that specific symptom --
the mover is grounded there (Path 5, not Path 6) and the actual
no-normal-recorded mechanism (SpherePath.PrecipiceSlide's
find_crossed_edge-false fallback) is independently confirmed byte-exact
retail behavior too. Recorded the concrete next step (re-run against
the faithful Setup-based door registration instead of the simplified
fixture) rather than closing on an unmet acceptance criterion.
- ISSUES.md #166: noted TS-4 and AD-55 landed (the AP-7-family
completion this note was waiting on); closure still pends the visual-
matrix scenario-5 recheck against live retail.
- Campaign P plan (2026-07-29-physics-parity-campaign.md) P2 status
block: TS-4 outcome (retired, not deferred), #116 outcome (shape-2
closed / shape-1 narrowed), AD-55 outcome (retired).
Docs-only; no build/test change required for this commit.

PhysicsBody.IsFullyConstrained now reflects real ConstraintManager state
(pushed every tick by the same per-tick pumps commit 2 wired), so
jump_is_allowed's already-ported gate (WeenieError 0x47) actually fires
while an object is rubber-banding hard against a server position
correction, closing the last piece of #167.
Housekeeping:
- Delete register row TS-35 (retired: the write side is no longer stubbed).
- Rewrite the stale doc comments on PhysicsBody.IsFullyConstrained,
ConstraintManager (class + IsFullyConstrained), PositionManager.ConstrainTo,
EntityPhysicsHost.PositionManager, and PlayerMovementController.PositionManager
that described the leash as permanently unarmed/stubbed.
- Close#167 in ISSUES.md citing the research doc and commits e0629145 /
7719d25b.
- Add an "as-ported" addendum to
docs/research/2026-07-30-constraint-leash-constants.md naming the actual
current seam owners (the doc's own open question flagged this as
implementer-verify-required post-J-slices).
- Update docs/plans/2026-07-29-physics-parity-campaign.md's P5 status and
CLAUDE.md's Campaign P summary to reflect #167's closure (items #153/#72
remain open in P5).
Verification: complete solution suite green - 9,978 tests, 5 skips, 0
failures across all 9 test projects (Core.Tests, Runtime.Tests, App.Tests,
Headless.Tests, Core.Net.Tests, Content.Tests, UI.Abstractions.Tests,
Bake.Tests, Cli.Tests).
Two tests proved "these two unrelated DAT reads ran concurrently" by
racing a fixed Thread.Sleep(40) window against .NET thread-pool
scheduling latency for a second Task.Run. Under the CPU contention of
a full `dotnet test AcDream.slnx` run (all 9 test projects' VSTest
hosts launch concurrently) plus a busy machine, thread-pool injection
can occasionally miss the window, making MaxConcurrentReads read 1
instead of 2 and failing the assertion with no underlying code defect.
RetailAnimationLoader and RetailPhysicsScriptLoader both coalesce
same-key reads correctly via ConcurrentDictionary<K, Lazy<T>>.GetOrAdd,
which is atomic and timing-independent (verified by reading, not just
running) - only the test's method of proving cross-key overlap was
timing-fragile. DecodedTextureCacheTests already uses the correct
deterministic-gate pattern; this brings RetailDatLoaderTests in line
with it via a Barrier-backed rendezvous instead of a sleep race.
Filed as #248 (docs/ISSUES.md) with the full attempt matrix: could not
catch the originally-reported AcDream.Content.Tests failure in the act
despite ~72 Content.Tests executions across four contention strategies
over ~30 full-suite-equivalent runs, though the general mechanism
reproduced 3x in AcDream.App.Tests's already-known zero-allocation
flake class (left untouched, out of scope here).

Campaign P Slice P4 item 2. TerrainSurface.SampleWaterDepth now returns 0.1
(was collapsed to 0) for a partially-water cell's dry corner, matching
retail's ObjCell.get_water_depth / calc_water_depth (via ACE's unambiguous
C# port). ValidateWalkable's formula was already byte-for-byte verbatim
(ACE ObjectInfo.ValidateWalkable line 124); only the constant was collapsed.
The old collapse's justification ("0.1 destabilizes the feet-exactly-on-plane
contact-touch check because dist > EPSILON skips SetContactPlane that tick")
is structurally true of retail too - traced and confirmed this slice: in ALL
THREE implementations (retail, ACE, acdream) a skipped touch-reassertion is
NOT a fall, because Contact/OnWalkable are STICKY -
PhysicsEngine.ResolveWithTransition's onGround computation ORs the fresh
per-call ContactPlaneValid with the seeded, persistent
PhysicsBody.TransientState.OnWalkable bit (itself written back by the
caller's own sticky TransientState). PhysicsEngine.SampleTerrainWalkable's
isWater = waterDepth >= 0.45f threshold means the restore does not flip the
dry corner's water classification (0.1 still < 0.45) - only the sink-in
depth changes. Full Core.Tests suite green (4038/2 skips, up from 4026)
proves the sticky-bit argument held in practice.
WATER_CONTACT_TS (TransientStateFlags.WaterContact, declared but never
written) is now mirrored alongside CONTACT_TS/ON_WALKABLE_TS at every commit
point that writes them: PhysicsObjUpdate.ApplySetPositionContact (projectiles
+ remote teleport), PhysicsObjUpdate.CommitSetPositionTransition (remote
teleport placement), and PhysicsEngine's per-resolve body-state commit (local
player + remote dead-reckoning + ordinary movers via ResolveWithTransition -
the actual SetPositionInternal-equivalent path). No signature changes needed:
body.ContactPlaneIsWater is already fresh by the time each function runs.
CollisionShadowVerifier audit: no change needed. It diffs graph-vs-flat BSP
traversal outcomes (ObjectInfo/CollisionInfo/SpherePath fields already
including ContactPlaneIsWater); it never touches PhysicsBody.TransientState,
and the water-depth constant is computed identically upstream of both
traversal modes, so it cannot introduce a new graph/flat divergence.
Filed #264 for the three items research explicitly left open (none block
this port): no confirmed retail consumer of WATER_CONTACT_TS was found (an
xref scan wasn't attempted - bitmask reads aren't text-greppable); the
CLandCell ENTIRELY_WATER ethereal/swim exemption from terrain collision was
not cross-checked; jump-in-water/swim-animation effects were not
investigated (out of physics/collision scope).
Conformance: Ap10WaterSemanticsTests covers SampleWaterDepth golden values
(NotWater/EntirelyWater/PartiallyWater wet+dry corners), the isWater
threshold non-flip, WaterContact mirroring in both PhysicsObjUpdate
functions, and two settle-to-rest end-to-end PhysicsEngine.ResolveWithTransition
scenarios (water: sinks exactly waterDepth below the plane and sets
WaterContact; dry: rests exactly on the plane and clears any stale
WaterContact bit).
Register: retired AP-10 (92 active AP rows, down from 93).
AcDream.Core.Tests: 4038 passed, 2 skipped, 0 failed.
