db9ad53c1c docs: Campaign LA — pinned launch-contract schema COMMITTED into plan LA1
The LA3 Opus review process note was right: the contract both sides
implement lived only in orchestrator prompts, which is exactly the drift
mode the pin exists to prevent (and it produced the paths-key CRITICAL).
The schema, field rules, probe-mode discriminator, and status vocabulary
are now a binding plan section; amendments change this text first,
implementations second. Ledger: LA3 fix round dispatched.

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.

Contract: docs/research/2026-08-05-c5b-contract.md (committed here, with its
section 14 implementation outcome appended).

e0f96a55bf fix(physics): C4 route 3 — portal placement authority (local player)
Removes a duplicate placement authority for local-player portal arrival.
Portalling worked before this change and works after it — this is not a
bug fix, EXCEPT that it found and fixed one dead-code production bug.

THE PRODUCTION BUG: TryExecuteCanonicalPortalPlacement re-read the
accepted destination at Place time, but TryBeginPortalReveal already
consumes that slot at Aim time — so the arm was 100% dead code and every
real portal Place refused with host-token-unavailable. Found only
because we refused to accept 7 skipped tests instead of chasing the
count to zero.

RETAIL IS THE GENERIC PATH FOR THE THIRD ROUTE RUNNING:
SmartBox::TeleportPlayer @0x00453910 = SetPositionSimple(dest, 1) with
flags 0x1012, followed by PlayerPositionUpdated.

BOTH INVERSIONS, WITH THEIR ANCHORS: unlike route 2, the leash IS armed
here (ConstrainTo @0x0045418A) and velocity is zeroed
(set_velocity @0x004541B4); unlike route 4b-3, the local teleport_hook
runs AFTER placement (@0x004538AE).

THE THREE-ROUND DEFECT CHAIN, HONESTLY:
- Round 1 released the player at the pre-teleport position while the
  anim stream marched on — the contract wrongly assumed Place re-fires
  (process rule 1's third occurrence this campaign).
- Round 2's fix inferred commit from a global PendingCount, which three
  non-committing paths also clear — making the SAME bug complete
  cleanly and silently. Strictly worse than round 1: round 1 at least
  tripped portal-complete-before-materialized.
- Round 3 latches the commit where it actually happens
  (ReconcileAndAcknowledgePortal), keyed on reveal generation and
  teleport sequence, via TryConsumePortalCommit. Two of the three
  required regression tests landed and are sabotage-verified on both
  hosts (ParkedPlace_ForgottenByOrdinaryMergeDoesNotLatchAsCommitted /
  HeadlessPortalPrepareDestinationForgottenByOrdinaryMergeDoesNotLatchAsCommitted).
  The third (force-arm-takes-the-slot) was judged unnecessary on review:
  with the inference gone, PendingCount is only a "don't ask yet" guard
  at both gates, so a force operation occupying or vacating the slot no
  longer changes an input the commit decision reads — the case collapses
  into what the landed test already discriminates.

THE B2/P3 RESOLUTION: both round-2 reviews were right about different
branches of the same synchronous call. RuntimePlacementProjectionSubscription
.OnPlacement acknowledges the FIFO head only when TryApply returns true;
a Place whose portal authority went stale (transit ended/superseded
while parked) used to return false, wedging every later entity's
placement receipt behind it forever. Both sinks
(RuntimePlacementPresentationSink, HeadlessRuntimePlacementProjectionSink)
now acknowledge-and-ignore a stale-authority Place instead of refusing
it. The regression test (RuntimePlacementPresentationSinkTests
.PortalPlace_StaleTransitHostOrSequenceIsAcknowledgedAndIgnored) had
been asserting the old, wrong `false` behaviour; it now asserts and
sabotage-verifies the fix.

Also lands: AP-144 (register discipline — the portal movement-event
send reuses the stricter UsePositionFromServer gate where retail's
SendMovementEvent is the looser autonomy_level != 0 test, diverging
only at level 1, currently unreachable), AP-145 + issue #318 (the
local-player collision-shadow presentation write bypasses its own
publisher's ShadowObjects write via a direct cache .Set(), self-healing
only once dedup diverges — filed, not fixed, pending a composition
test), AD-42 deleted (its last citation retired by the canonical portal
arm), AD-2 updated (the wait-cue's trigger predicate now covers a
second cause), and two documentation corrections: the enter_world
misattribution (both call sites are in SmartBox::HandleCreateObject,
only one in the player branch — portal arrival is TeleportPlayer, not
enter_world) and the stale "local player never reaches this path"
comment on the generic-remote-render-pose write.

Suite: 11,090 passed / 4 skipped / 0 failed. No new skips, nothing
weakened.

STILL OWED: the connected two-client gate, with
ACDREAM_PROBE_LOCAL_TELEPORT=1, scored only if [local-tp] lines
actually appear in the capture — and explicitly NOT scored as covering
issue #318 (no composition test yet asserts PhysicsEngine.ShadowObjects
directly).

6dc7ba51ee feat(physics): C4 route 4b-3 — remote teleport + cell-less through the canonical placement
Flips the last remote classification (SetPosition: teleport-advanced and
cell-less) onto 4b-1's RuntimeRemotePlacementDriveController, runs retail's
teleport_hook before the placement, and deletes the legacy remote-teleport
machinery. Contract: docs/research/2026-08-04-c4-route-4b-3-contract.md.

Retail: MoveOrTeleport @0x00516330's branch @0x00516386 -> teleport_hook
@0x005163EF -> SetFlags(0x1012) @0x00516414 -> SetPosition @0x00516420 ->
return 1 @0x00516438. The hook @0x00514ED0 runs BEFORE the placement and
regardless of its outcome. Retail places this branch unconditionally, at any
distance and any contact state (arg4 is read only @0x0051638E, after the
branch) — which is what retires AP-137's cell-less enqueue-vs-place delta.

D1 — the classifier's cell-less input is now the PRE-merge committed cell.
Retail's predicate is `this_1->cell == 0`, the BODY's own cell at
MoveOrTeleport entry (this_1 is assigned from this @0x00516334). acdream fed
the POST-merge canonical.FullCellId, which RefreshSnapshot ->
RefreshDerivedState -> SetFullCell has already stamped with the accepted wire
cell; a zero wire cell fails validation into RejectedData first. The shipped
remote cell-less predicate was therefore dead code, not merely different from
remotePlacementRequired. Threaded via a builder overload; route 1's overload
is untouched. The graphical !IsSpatiallyVisible arm of
projectionRequiresTeleportHook is deleted — a presentation predicate with no
retail analogue that fired the teleport machinery on a routine hot path.

Deleted: RemoteTeleportController (605), RemoteTeleportPlacement (85),
RemoteShadowPlacementSynchronizer (49), their 1,709 lines of tests, the
remotePlacementRequired predicate, the TeleportHookRequired plumbing, the
legacy pre-operation ConstrainTo fallback, and the player arm's legacy
!IsGrounded fallback. Net -2,030 lines.

Structural fix (two independent Opus reviews, round 1 FAIL/FAIL): three of the
four MAJORs were one defect — OnPosition carried two parallel inline copies of
the routing tail (player-guid, NPC-guid) that had drifted. Extracted
RunRemoteArmTail (3 call sites) and ApplyWireAirborneLeftoverBookkeeping (2),
both branches now share one implementation.

  A1  ToConstraintArm mapped AirborneSnap -> AirborneNoOperation, so the NPC
      arm armed ConstrainTo ZERO times for an out-of-contact wire-grounded
      creature — a regression this slice introduced while closing a
      structurally identical hole. Now maps to NearInterpolate; switch made
      total with a throwing default proven unreachable.
  R1  D2's write-nothing shape existed on the player arm only; NPC packets
      fell through and wrote the body. Retail makes no player/NPC distinction.
  R2  report_collision_end(this,1) @0x00514F31 was bound to
      ShadowObjects.Suspend, a port of a DIFFERENT retail function
      (remove_shadows_from_cells) that teleport_hook never calls. Now routes
      to RuntimeCollisionReportingState.LeaveWorld, which wraps the private
      ForceEnd in an admission-blocking transaction so a DoCollisionEnd
      callback cannot recreate the contact table.
  R3/A2 A teleported NPC synthesized ServerVelocity from the teleport distance
      (~1,000+ m/s) and planned a run cycle from it. Both the install and
      RemoteServerControlledVelocityCycle.Apply now gate on !isTeleportRoute.

BISECT HAZARD — A1's fix is correct only BECAUSE R1 landed. AirborneSnap is
reachable wire-airborne on the NPC arm only while D2's shape is missing there.
Reverting R1 alone silently inverts A1 into the opposite divergence: arming
where retail returns 0. Revert both or neither.

Also in the velocity hunk: the NPC block's two !IsPlayerGuid(update.Guid)
guards were dropped when it was wrapped in `if (!isTeleportRoute)`. Safe — all
five exit paths of the enclosing IsPlayerGuid block return, so the predicate is
unconditionally false below it — but it was unremarked by both reviews.

Register: AP-137 REWRITTEN (not deleted) to the surviving acdream-only
divergences — null classification during the login window and Rejected*
through UnroutedCatchUp keep a row. AD-42's RemoteTeleportController citation
retired; AP-136/AP-138 writer lists corrected to the two surviving non-Position
rebucket writers; AP-138 gains the teleport arm as a second producer of the
visible-without-collision residual (retirement path remains #309). AP-135 is
untouched and its two airborne bookkeeping writes are preserved on both arms.
AP-131 does not retire; #276 does not close.

Proof obligation 1: ParkCollisionResidents' overlap throw stays unreachable —
the teleport arm adds packets to the same TryBeginExclusiveAuthoredPlacement
one-operation-per-key machinery the far arm uses, opens no new operation shape,
and every DeferredCell outcome cancels synchronously with
restoreCancelledPark: true. The guarded property remains
HasOldPrefixPlacementDebt's stall, not a throw (4b-1's B2 caveat stands).

Correction to an earlier claim: LiveEntityPresentationController's
_activePlacementOwners was NOT write-never at HEAD —
remotePlacementRequired -> BeginPlacement -> Begin -> BeginAuthoritativePlacement
was a live writer chain. It becomes write-never BECAUSE this slice deletes that
chain, which is why deleting the dead half is behaviour-preserving.

Probe: ACDREAM_PROBE_REMOTE_TELEPORT=1 emits one [remote-teleport] line per
routed arm (guid, cause, hook-ran, placement status). TEMPORARY, strip with the
probe family.

Carried, disclosed not fixed: no dedicated bidirectional collision-partner test
for R2 (the wiring, not LeaveWorld itself, is what lacks coverage); the
stress test's teleport step drives hand-written field assignments rather than
the canonical arm; the per-packet runTeleportHook closure allocation (network
path, not the resolve path Slice I's 0 B discipline governs — file before
route 5 adds a fourth call site). B2: IRuntimeCollisionReportObserver has zero
production implementations, so retail's bidirectional DoCollisionEnd half still
reaches no gameplay consumer — this fix closes the wrong-function binding, not
that nobody listens.

Complete Release suite MEASURED at 11,013 passed / 4 skipped / 0 failed
(baseline 11,027/4/0; net -14 = ~33 deleted test cases against ~19 added).
Neither known flake fired (#302 PortalProjectionTests GC-allocation, #308
NakEmissionTests wall-clock).

STILL OWED: the two-client connected gate, which MUST use an NPC/creature
teleport target. Both round-1 MAJORs lived on the NPC arm and the velocity
cycle early-returns for 0x50xxxxxx guids, so a player target structurally
cannot observe A1, A2, or R3.

7f1c1f5aa6 feat(physics): C4 route 4b-2 — remote far snap through the canonical placement
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.

9966b53174 feat(physics): C4 route 2 — ForcePosition through the canonical placement
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.

Known gap, recorded not claimed: the plan's acceptance item 2 is unmet. The App
double-write check is a source pin, and "the committed projection moves the
render entity" is uncovered at any layer (#292). Filed alongside: #286-#291,
#293-#296.
