Losing window focus calls CameraPointerInputController.HandleFocusChanged
-> MouseLookController.EndForLifecycle -> PlayerMovementController
.EndMouseLook, and EnsurePublishedForRuntimeOperation throws when the
controller exists but is not yet published (mid-login) or already retired
(post-logout). A focus callback can land in either window, so a simple
alt-tab during the login stream took the whole process down with an
unhandled InvalidOperationException. Hit live during the Campaign A
listening-session launches.
EndAndRestoreCursor already guarded 'no controller'; publication state is
the finer-grained form of the same condition, so the guard is completed
with the new CanExecuteLiveMovement predicate (the exact lifecycle set
EnsurePublishedForRuntimeOperation accepts) rather than wrapping the call
in a catch. Cursor restore still runs unconditionally - presentation is
always safe. Published-controller behaviour is unchanged.
Also files issue #357: the login placement stall this session exposed
(reveal ready=True, player Place edge never executes, world never opens).
That one is NOT fixed here - full evidence chain, wire capture, and probe
output are in the issue. It is a placement-domain bug and blocks the
Campaign A listening gate.
Suite: green except the known load-dependent measurement flake
(RuntimeCollisionReportingStateTests allocation pin), which passes in
isolation.

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

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.

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.

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).

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).

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

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

Campaign P remaining-physics-divergence, placement cutover slice C3c
(docs/plans/2026-08-02-placement-cutover.md). Both production hosts now
register every initial Create through the residence + continuation-
executor + first-entry-conductor machinery (C0-C3b):
- Graphical (route 1): RegisterEntityWithInitialResidence at Create; the
shared RuntimeFirstEntryDriveController pumps both conductors from the
placement-receipt flow; MaterializeProjection and RebucketLiveEntity
are presentation-only while a residence is ACTIVE (ExecutorCompleted is
the presentation-binding receipt); post-residence entities take the
full legacy path including the prepare_to_enter_world clock edges.
PlayerModeController attaches presentation to the Runtime-published
controller; its legacy resolve/step-heights/host-construction path is
deleted; presentation-only rollback (retail has no entry-flow rollback).
- Headless (route 8): OnSpawned registers with residence when a drive
exists; content-less sessions keep the pre-flip direct registration;
SynchronizeLocalPlayer/CreateController/ApplySetupStepHeights deleted;
prepared-collision read failure is a typed AwaitingCollisionSource
retry; far remotes outside the service window complete celless.
- RuntimeLocalPlayerMovementState.Controller setter sealed internal; all
controller mutation flows through the publication lifecycle.
Fix slices landed within this cutover, each dual-gated:
- F1: live movement-stat/server-physics application routed through the
Runtime ownership seam (post-logout ingest crash on the retired
controller eliminated; RuntimeMovementSkillProjection deleted).
- F2: login activation wedge - collision-admission prefix gate factored
out of the seal (reentrant-commit RejectedAuthority), rearm generation
identity corrected, PlayerModeAutoEntry requires the Runtime-published
controller (world reveal can no longer seal unmaterialized).
- F3: landblock-prefix 0-sentinel replaced by explicit absent-id guards;
map-corner landblocks (grid row/col 0) fully legal through admission,
park/rearm/retire, quiescence, and outdoor shadow seeds.
- F5: local-player first-entry ground contact seeded by the shared
SpawnPlacementSettler (moved App->Core) at FinalizeActivation - the
retail first-gravity-frame touch (enter_world 0x00516170 carries no
seed); the legacy unconditional force-seed is overwritten by a real
floor-found contact; airborne spawns stay airborne; outbound contact
bit verified end-to-end. Fixes the standing-cast 'You can't do that
while in the air!' rejections.
- R1 (dual-review round): login constraint leash armed at the committed
placement (HandleReceivedPosition 0x00453FD0 analog); register rows
AD-61 (settle-timing compression now covering the local player) and
AD-42 (repointed off the deleted resolve split) in this commit;
residence-conversion owner API; wire-landblock guards; drive-pending
ledger in IsConverged; route attach/detach latch; executor-drain drift
model documented + source-pinned.
Gates: Runtime 1,003, App 4,039/3 skips, Headless 79, complete solution
10,816/0 failed/4 skips (Release, -m:1); connected lifecycle/reconnect
gate PASS (logs/connected-world-gate-20260802-175401; graceful exits,
world-visible, zero airborne rejections). The nine-stop soak remains red
for the pre-existing 6b28ff99 whole-world collision-clone throughput
regression (attributed with evidence; scheduled as its own slice before
C5). Dual Opus reviews (retail-conformance + adversarial): delta PASS.

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
velocity from the deleted get_state_velocity-overwrite era); de-overlap
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).

Capture bisect (docs/research/2026-07-30-265-capture-bisect.md, mined
from artifacts/matrix-session2-resolve.jsonl records 3415-3434) traced
#265's lost roof slides / permanent landing freeze and #166's missing
downhill sled to a pre-existing (2026-07-20, ten days before Campaign P
- not a regression) mechanism in PlayerMovementController.cs's grounded
quantum block: it hand-zeroed Velocity.X/Y to exactly zero every tick
once OnWalkable whenever animation root motion drives the walk (the
production graphical local-player path), discarding any residual
horizontal momentum a fall left on the body before calc_friction
(AP-7/AD-55, already correctly ported) or PhysicsBody.
UpdatePhysicsInternal's Euler integrator ever got a chance to act on it.
Two changes:
1. PhysicsEngine.cs now syncs body.GroundNormal (the vector
calc_friction dots velocity against, per retail
CPhysicsObj::calc_friction 0x0050ee70's `contact_plane.Normal` read)
from the committed ContactPlane.Normal at the same commit point that
already publishes ContactPlane. GroundNormal had zero production
writers before this and silently defaulted to Vector3.UnitZ forever
- even surviving velocity would have been tested against a fake
flat-ground normal on any real slope. Core-level, so player, remote,
ordinary, and projectile movers all benefit uniformly.
2. PlayerMovementController.cs's grounded block no longer reconstructs
Velocity at all for the animation-root-motion case (only the
headless/test-controller get_state_velocity fallback still does,
unchanged). Root motion continues to fully own commanded locomotion;
this only stops destroying whatever Velocity already holds, letting
it compose with root motion through the same ResolveWithTransition
sweep exactly as retail's CPhysicsObj::UpdatePositionInternal
composes both channels.
Symptom (a), the uphill-jump bounce, traces to a SEPARATE, byte-exact
(re-verified against acclient_2013_pseudo_c.txt:282647-282760),
already-closed retail mechanism (AD-25, PhysicsObjUpdate.
HandleAllCollisions's shouldReflect gate) - confirmed orthogonal to this
fix, not addressed here (see the research doc's as-fixed addendum §9.5).
Issue265SteepSlopeCaptureBisectTests.cs gains a composed harness
(ReplayRealRoofLandingComposed) mirroring PlayerMovementController.cs's
per-tick composition against Core types only, proving: the old model
reproduces the mined freeze exactly; the new model survives the landing
and slides continuously (the real captured geometry glides at constant
velocity per retail's own dot>=0.25 early-return - AP-7); a synthetic
dot<0.25 case shows genuine exponential decay via calc_friction; and a
synthetic uphill-bounce case proves the fix changes nothing about
HandleAllCollisions's reflection decision.

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).
Wire ConstraintManager.ConstrainTo at every current acdream inbound-position
acceptance seam, matching retail SmartBox::HandleReceivedPosition
(0x00453fd0):
- Remote (player + NPC): LiveEntityNetworkUpdateController arms right after
the hard-teleport branch (remotePlacementRequired) returns - reaching that
point already means MoveOrTeleport did NOT hard-place - anchored to the
object's own live IPhysicsObjHost.Position.
- Local player teleport: PlayerMovementController.SetPositionCore now runs
UnConstrain (retail teleport_hook 0x00514ed0, previously a no-op because
nothing armed the leash) then re-arms anchored to the just-snapped
position, composing with the existing StopCompletelyAtPhysicsObjectBoundary
velocity zero rather than duplicating it. CommitPreparedPosition mirrors
the same pair for the deferred player-mode-entry commit path.
- Local player ForcePosition: PlayerMovementController.BlipPosition arms
with NO preceding UnConstrain (retail BlipPlayer/SetPositionSimple
survives motion/velocity/stick, and the leash is no different).
Push PhysicsBody.IsFullyConstrained from PositionManager.IsFullyConstrained
at the SAME per-tick chokepoint each pump already runs AdjustOffset
(PlayerMovementController.Update, RuntimeRemotePhysicsUpdater.Tick/TickHidden)
so TS-35's read gate in jump_is_allowed sees live state instead of a stub
that is never written.
Tests: local-player arm/teardown/rearm/taper/jump-refusal (Runtime.Tests,
PlayerMovementControllerTests), remote-tick IsFullyConstrained push
(Runtime.Tests, RuntimePhysicsStateTests). Full Core/Runtime/App suites
green with no regressions.
Campaign P Slice P3 item 3. The wire parse (CreateObject's
PublicWeenieDesc._bitfield), the decode (EntityCollisionFlagsExt.
FromPwdBitfield), the per-GUID storage (ClientObjectTable.
PublicWeenieBitfield), and the exemption logic (CollisionExemption.
ShouldSkip) all already existed and were already correct -- every
mover-flags call site just fed a GUID-prefix IsPlayer heuristic instead
of the real per-entity PK/PKLite/Impenetrable state (retail
OBJECTINFO::init 0x0050cf30 state |= 0x80/0x800/0x1000).
Port:
- EntityCollisionFlagsExt.ToMoverState translates the decoded PWD
bit-space into the ObjectInfoState bit-space FindObjCollisions
actually reads -- two different numberings that must not be
confused. Deliberately does not translate IsPlayer (every call site
already derives that correctly from its own GUID heuristic per
#184 Slice 2b).
- EntityCollisionFlagsExt.ResolveMoverPvpState is the one shared
ClientObjectTable-backed lookup (guid -> ObjectInfoState), replacing
what would otherwise have been three separate inline copies across
GameWindow/LivePresentationComposition/RemoteTeleportController.
- Threaded as a new optional moverPvpState parameter through
RuntimeRemotePhysicsUpdater.Tick/TickHidden and
RuntimeOrdinaryPhysicsUpdater.TryBegin (default None preserves every
pre-P3 caller unchanged), and as PlayerMovementController.OwnPvpFlags
for the local player's own two resolve call sites.
- TS-23 section 12b: PlayerWeenie.JumpStaminaCost's pk parameter now
reads the real PlayerKillerStatus(0x86)/LastPkAttackTimestamp(0x91)
pair against retail's 20-second recency window
(pkStatus in {4, 0x40} && (timestamp + 20.0) >= now), replacing the
P1 hardcoded false. RuntimeMovementSkillState/Snapshot and
LiveSessionEventRouter.RecomputePvpStatus push both the PWD bitfield
and the PlayerKillerStatus pair reactively, riding the SAME
ClientObject event triggers RecomputeBurden already uses.
- A conformance test caught a genuine precision bug in the first
PK-timer clock choice: DateTimeOffset.UtcNow's Unix-epoch seconds
(~1.7 billion) loses ~128 seconds of precision in a 32-bit float,
silently swallowing the entire 20-second window. Switched to
Environment.TickCount64 (small, monotonic magnitude) -- also the more
retail-plausible basis, since LastPkAttackTimestamp is itself a wire
PropertyFloat and retail's Timer::cur_time is almost certainly a
process/session-relative counter for the same precision reason, not
an absolute epoch.
Non-PK invariant (the acceptance criterion): an entity with no
ClientObjectTable row, or a row whose PublicWeenieBitfield is null or
0, resolves to ObjectInfoState.None -- a no-op OR into moverFlags,
bit-identical to every pre-P3 caller's hardcoded value. A dedicated
test drives two real ClientObjectTable rows through
CollisionExemption.ShouldSkip and confirms PK-vs-PK collides while
PK-vs-non-PK and non-PK-vs-non-PK both stay exempt (walk through).
Register: TS-23 retired (both the collision-flags and PK-timer halves);
the stale "M2 combat must land TS-23" phase-gate note removed.
dotnet build + dotnet test (Core.Tests 4008/2 skip, Runtime.Tests
425/0, App.Tests 3968/3 skip, complete solution build) all green.

Campaign P Slice P3 item 1. Retail CPhysicsObj::transition (0x00512dc0)
seeds the collision sweep from CPartArray::GetSphere (the Setup's own
<=2-sphere list, each origin+radius scaled by m_scale) via
SPHEREPATH::init_sphere (0x0050c670) -- not from a symmetric two-scalar
(radius, height) capsule reconstruction. The human Setup 0x02000001's
authored spheres are (0,0,0.475) r=.48 and (0,0,1.350) r=.48; the old
reconstruction from (0.48, 1.835) produced (0,0,0.48) + (0,0,1.355), a
5 mm head-center offset the TS-46 register row documented as a residual.
Port:
- SpherePath.InitPath gains a sphere-list overload (ImmutableArray<
FlatCollisionSphere>, scale) sharing a new InitPathCore with the
existing (radius, height) overload, which is now the degenerate
2-scalar case of the same code -- byte-for-byte unchanged, so every
captured-fixture replay (CellarUpTrajectoryReplayTests,
DoorBugTrajectoryReplayTests, CellarLipWedgeTests) keeps passing
unmodified.
- PhysicsEngine.ResolveWithTransition gains optional sphereList/
sphereScale parameters; empty/default preserves the legacy scalar
path for every pre-existing caller.
- LiveEntityMotionRuntimeController.GetSetupMoverShape is a new sibling
of GetSetupCylinder (left untouched) that resolves the Setup's own
sphere list plus Setup-derived step-up/step-down
(CPartArray::GetStepUpHeight/GetStepDownHeight, 0x005180d0/0x005180f0,
x ObjScale, 0.4 m fallback matching the pre-existing literal).
- Threaded through PlayerMovementController (both resolve call sites,
new SphereList property set by PlayerModeController.ApplyStepHeights
and the Headless world projection), RuntimeRemotePhysicsUpdater
(Tick + TickHidden), and RuntimeOrdinaryPhysicsUpdater.TryBegin.
Remote/ordinary step heights are now Setup-derived instead of a
hardcoded 0.4f literal. Projectile and camera-probe sweeps are
untouched (already single-sphere-exact).
- PlayerModeController.ApplyStepHeights also now applies the x ObjScale
multiply to the player's own step heights (previously only the
remote/ordinary paths did), closing an adjacent gap the P3 research
flagged.
Ts46SphereListConformanceTests proves the sphere-list overload sees the
exact dat spheres (not the reconstruction), that the scalar overload is
unchanged, and that ResolveWithTransition's sphereList parameter
actually drives the sweep (a decoy-scalar control pair using a
head-height obstacle sphere).
Register: TS-46 retired (both residuals it named are closed); header
count corrected to 40 active TS rows.

Ports the retail CACQualities/EncumbranceSystem/MovementSystem chain
(named-retail decomp pc 256393/412901-414050/416169-416320/695958+) so
PlayerWeenie's run rate, jump height, jump permission, and jump stamina
cost are real functions of burden, current stamina, and vitae/skill
enchantments instead of stubs.
Core:
- New EncumbranceSystem.cs (delegates to the already-verified
BurdenMath formulas — one source of truth for the burden HUD and
movement physics) and MovementSystem.cs (GetRunRate/GetJumpHeight/
JumpStaminaCost/GetJumpPower, decomp-cited; ACE cross-referenced
where BN dropped the general-case arithmetic entirely).
- PlayerWeenie rewritten as the CACQualities-shaped composition:
CanJump gates on burden (<2.0 load, UN-8 — x87 polarity resolved by
plausibility, Ghidra MCP unavailable this slice), JumpStaminaCost
returns the real ceil((load+0.5)*power*8+2) cost and always affords
it (matches decomp — retail's own function never refuses; "weak"
jump comes entirely from the stamina==0 skill-zeroing gate inside
InqRunRate/InqJumpVelocity, not a hard refusal), SetStamina wires a
null="unknown, don't gate" sentinel preserving every pre-P1 test.
- EnchantmentMath.GetMod gained an optional StatModType flag filter
(GetSkillMod convenience wrapper) so the SAME vitae/family-stacking
machinery already used for vital-max buffs now also answers "what's
the vitae+skill-enchantment-adjusted Run/Jump skill" — reusing the
M3 active-enchantment state, not a new engine.
Runtime:
- RuntimeCharacterState now stores the pre-EnchantSkill base run/jump
skill and recomputes the adjusted value (vitae first, then matching
Skill-flagged buffs, floor 0.5, truncate) on every base push AND on
every Spellbook.EnchantmentsChanged notification — a vitae change
alone moves the produced rate without a fresh PlayerDescription.
- RuntimeMovementSkillState extended with Burden/CurrentStamina
(RuntimeMovementSkillProjection.ApplyTo pushes both through the
existing seam); LiveSessionEventRouter recomputes burden from the
same Strength+aug-property+EncumbranceVal inputs the burden HUD
already assembles (reacting to the same ClientObjectTable events)
and pushes current stamina from LocalPlayerState vital updates.
- Wires the previously dead-lettered ReportExhaustion() R3-W4 seam:
LiveSessionRuntimeFactory's OnMovementStatsUpdated callback re-
applies the current snapshot to the live controller and forces an
immediate movement re-evaluation on any skill/burden/stamina change.
Register: retires TS-5 (CanJump/JumpStaminaCost stubs) and AP-25 (no
vitae in pushed skill). Adds AP-127 (two minor unmodeled retail bonus
properties + the stamina-buff-adjusts-local-copy nuance, deliberately
out of the bounded "run/jump query path only" scope) and UN-8 (the
CanJump x87 polarity call, flagged for a future Ghidra MCP
confirmation pass). Extends TS-23 (PlayerKillerStatus not parsed) to
cover JumpStaminaCost's new pk parameter, hardcoded false pending P3.
Full pseudocode + retail citations + the vitae/skill-level finding in
docs/research/2026-07-30-stat-coupled-movement-pseudocode.md.
Release suite: Core.Tests 3977/2 skips, Runtime.Tests 425/0 skips,
App.Tests 3968/3 skips — all green. (One pre-existing, unrelated Debug-
only flake in LandblockBuildOriginTests reproduces on the pre-P1
baseline and passes in Release; not touched here.)

Move the canonical local movement controller, body/motion managers, object clock, movement wire data, and MTS/jump/AP sender into AcDream.Runtime. Replace process skill defaults with typed Runtime character options, make graphical and direct commands borrow one autorun owner, retain the construction-time PartArray seam, and include movement in terminal ownership convergence.
Preserve the accepted pre-inbound movement/jump and post-inbound autonomous-position order while moving the exact packet/cadence fixtures into Runtime tests. Add graphical/direct parity, two-instance isolation, teardown, allocation, architecture, and divergence-path coverage.
