Replace timeout-polled in-world UDP receives with one cancellable caller-buffered socket operation. Transfer only right-sized pooled datagrams through the FIFO, return every ownership edge deterministically, and send caller spans without a transport copy while preserving handshake pacing and ACK order.
WorldSession.NetReceiveLoop wrapped its entire while loop in a single
try/catch, so ANY non-timeout SocketException permanently killed the
background receive thread: the catch block at the loop's end was empty
(misattributed the error to "socket closed during shutdown"), and the
finally called _inboundQueue.Writer.TryComplete(), which silently and
irrecoverably stopped all inbound processing for the rest of the
session — no log line, no recovery path, and LiveSessionHost.Reconnect
has zero production callers to notice.
The realistic trigger is a well-known Windows UdpClient quirk: an ICMP
"port unreachable" reply to an EARLIER Send (e.g. against a stale ACE
session that already tore down its socket) surfaces as a
WSAECONNRESET SocketException on this socket's NEXT, completely
unrelated Receive call. NetClient.Receive already swallows the
expected SocketError.TimedOut heartbeat case; anything else reaching
WorldSession was a real, transient, per-datagram error being treated
as session-fatal.
Three changes, root-cause not a band-aid:
- NetClient's constructor now disables SIO_UDP_CONNRESET reporting on
Windows, so a delayed ICMP error can't poison receives at all.
- NetReceiveLoop now catches SocketException PER ITERATION, logs it,
and continues polling instead of exiting. The existing clean-shutdown
paths (cancellation, ObjectDisposedException during Dispose) are
unchanged — only the non-timeout-socket-error case that used to kill
the loop is now recoverable.
- NetClient.Receive no longer calls the ReceiveTimeout setter (a
setsockopt syscall) on every single call — only when the requested
timeout differs from the last-applied value, cached in a new field.
This was an unrelated but adjacent finding (4x/sec syscall churn at
the 250ms heartbeat cadence) in the same audit.
No change to outbound wire behavior, ack cadence, heartbeat interval,
or datagram ordering — this is purely receive-loop resilience.
Tests: NetClientTests gained a SIO_UDP_CONNRESET construction smoke
test and two ReceiveTimeout-caching tests. A new
WorldSessionNetReceiveLoopResilienceTests drives the actual private
NetReceiveLoop method (via the existing internal
IWorldSessionTransport seam + reflection) with a scripted transport
that throws a non-timeout SocketException on the first call, proving
the loop survives it and keeps enqueueing subsequent datagrams — fully
deterministic, no real sockets. Full solution suite green: 3204/3206
Core, 3462/3465 App, 552/552 Core.Net (skips pre-existing).

Lands the codex-worktree D.2b stream plus the extraction the 2026-07-02
UI architecture review mandated before commit:
- ItemInteractionController: single owner of double-click use/equip/
container-open, targeted-use mode (health kits), drag-out drop;
toolbar shortcut drags don't drop the real item. ItemEquipRules for
multi-slot (coat) coverage via equip masks.
- Cursor phase: CursorFeedbackController (semantic priority chain:
drag > resize > window-move > target-mode > text) + RetailCursorCatalog
(enums 0x27/0x28/0x29, hotspot 14,14; ClientUISystem::UpdateCursorState
0x00564630) resolved through the portal EnumIDMap chain by
RetailCursorResolver; RetailCursorManager applies dat cursor art to the
OS cursor. Register row AP-72 covers the OS standard-cursor fallback.
- Character window goes live: CharacterSheetProvider owns sheet assembly,
XP-curve/raise-cost math and the raise flow — extracted out of
GameWindow per Code Structure Rule 1 instead of committing the ~430-line
feature body there. Optimistic XP/credit debits go through eventful
store APIs (new ClientObjectTable.UpdateInt64Property +
LocalPlayerState.DebitIntProperty/DebitInt64Property) instead of raw
property-dictionary writes; register row AP-73 covers the still-missing
raise ledger (#163).
- RetailWindowFrame: the shared nine-slice window mount recipe; the
character window uses it, remaining windows migrate via #164.
- Status-bar buttons toggle inventory/character windows; retail row-major
backpack ordering; WorldSession.SendUseWithTarget + raise/train sends.
GameWindow shrinks 14,214 -> 13,877 lines despite the new features; the
sheet/raise logic is unit-tested in CharacterSheetProviderTests instead
of trapped in the god object. Build green; full suite 3,286 tests pass.

Port retail's three-stamp inbound gate for 0xF74C UpdateMotion:
- MotionSequenceGate (Core/Physics): CPhysicsObj::is_newer (0x00451ad0)
wraparound u16 compare, verbatim per ACE PhysicsObj.is_newer (the BN
pseudo-C setcc returns are garbled; ACE + branch structure are the
oracle). Gates: INSTANCE_TS at dispatch (stale incarnation drops
before any stamp is touched), MOVEMENT_TS strictly-newer (stamped
BEFORE the server-control check, per CPhysics::SetObjectMovement
0x00509690), SERVER_CONTROLLED_MOVE_TS drop-when-stored-newer.
- Seed from CreateObject's PhysicsDesc timestamp block (index 1 =
ObjectMovement now parsed; ACE WorldObject_Networking.cs:411-420
order) — without seeding, entities whose movement sequence is past
0x8000 at spawn would drop every UM against a zero stamp.
Adopt-on-first / advance-only-after, so the #138 rehydrate replay of
retained spawns cannot regress live stamps.
- UpdateMotion + EntitySpawn now carry instance/movement/serverControl
sequences + isAutonomous (was parsed-past; isAutonomous feeds the
S2 funnel's last_move_was_autonomous). Gate wired at the top of
OnLiveMotionUpdated before any state mutation; [UM_STALE] diag under
ACDREAM_DUMP_MOTION / ACDREAM_REMOTE_VEL_DIAG; gate dropped with the
entity on DeleteObject.
Register: AD-32 added (adopt-newer-incarnation instead of retail's
QueueBlobForObject); TS-26 updated (UM side closed, UP side open).
Deviation map: docs/research/2026-07-02-inbound-motion-deviation-map.md.
19 new gate tests + parser coverage; full suite 3276 green.

Brings the 134 D.2b UI commits onto the physics/collision development line so
main can fast-forward. Today's #149 (BSP-less static collision) + #150 (open
doors fully passable) + the full collision/streaming/dense-town-FPS arc meet
the paperdoll/inventory work.
# Conflicts:
# docs/ISSUES.md
# docs/architecture/retail-divergence-register.md
PickupEvent (0xF74A) and DeleteObject (0xF747) are semantically distinct:
- 0xF747 = weenie DESTROYED → evict from ClientObjectTable (weenie_object_table)
- 0xF74A = object LEFT THE 3D WORLD VIEW (moved into a container) → remove
the 3D WorldEntity, but the weenie persists in ClientObjectTable
Before this fix, both paths fired EntityDeleted identically, causing
ObjectTableWiring to evict the weenie from ClientObjectTable. The follow-up
InventoryPutObjInContainer (0x0022) then tried MoveItem on an unknown guid
and no-op'd, so the unwielded item simply vanished.
Fix: add `bool FromPickup` (default false) to DeleteObject.Parsed. WorldSession
sets it true on the PickupEvent path and false on the DeleteObject path.
ObjectTableWiring.Wire's EntityDeleted handler skips table.Remove when
FromPickup is true, preserving the weenie for the container-move echo.
GameWindow.OnLiveEntityDeleted (3D entity removal) is untouched — it fires
for both pickups and destroys, as intended.
Divergence register: AP-65 added (data ghosts for other-player pickups until
teleport/relog clear; harmless — no UI queries ContainerId 0).
Tests: +5 (DeleteObject FromPickup parser regression; wiring retain/evict
semantics; Parsed default/explicit FromPickup). 343/343 pass.

After a teleport ACE floods a town's CreateObjects; WorldSession.Tick drained the
ENTIRE inbound queue every frame, each spawn hydrating mesh+textures under _datLock
on the render thread — monopolizing the update loop for ~a minute and starving the
streaming apply, so only the destination landblock loaded and neighbors trickled in
(visible at high render-FPS because update/render are separate Silk.NET callbacks).
Bound the per-frame drain to a ~4ms wall-clock budget once InWorld (handshake uses
the blocking PumpOnce path, never Tick). A time budget self-adapts to the highly
variable per-datagram cost; the tail stays queued (unbounded channel, FIFO) and
drains over the next few frames. Acks are queued per packet BEFORE the heavy handler
(WorldSession.cs:680), so deferring the tail only delays the tail's acks a few frames
— within ACE's tolerance (holtburger defers acks on a flush cadence; verified in
references/holtburger session/send.rs). Budget decision extracted as a pure testable
static (4 unit tests).

Add 3 new events (PlayerIntPropertyUpdated, StackSizeUpdated, InventoryObjectRemoved)
and their payload record types near the existing ObjectIntPropertyUpdated event.
Add 3 switch cases in the GameMessage dispatcher immediately after the
PublicUpdatePropertyInt (0x02CE) branch for:
- PrivateUpdatePropertyInt (0x02CD) — no-guid player-own property
- SetStackSize (0x0197) — stack count + value update
- InventoryRemoveObject (0x0024) — remove from inventory view
No test seam on the switch; verified by build + parser tests (Tasks 3/4/5)
+ live run per codebase convention (see ObjectTableWiringTests comment).

Task 9 of the B-Wire inventory-wire plan. Adds three outbound C→S GameAction
builders to InventoryActions.cs (DropItem 0x001B, GetAndWieldItem 0x001A,
NoLongerViewingContents 0x0195) plus matching opcode constants after TeleToPoiOpcode.
Adds SendDropItem/SendGetAndWieldItem/SendNoLongerViewingContents wrappers to
WorldSession.cs (after SendRemoveShortcut, ~line 1157), following the exact same
NextGameActionSequence() + SendGameAction() pattern as the existing Send* family.
Three byte-layout tests added to InventoryActionsTests.cs (12 total, all green).
Core.Net build clean. Unblocks B-Drag (drop) and container-open (NoLongerViewingContents
on close) call sites in the inventory controller.

ShortcutStore lands in AcDream.Core.Net.Items (not AcDream.Core.Items) because
it depends on PlayerDescriptionParser.ShortcutEntry; placing it in AcDream.Core
would create a circular dependency (Core.Net already references Core). The test
lives in AcDream.Core.Tests which gets Core.Net transitively via App.
BuildAddShortcut signature corrected from the old (seq, slotIndex, objectType,
targetId) 4×u32 layout to the retail ShortCutData wire format confirmed in the
action-bar deep-dive: Index(u32), ObjectId(u32), SpellId(u16), Layer(u16).
The old BuildAddShortcut_ThreeFields test is replaced by two new tests that
verify both item and spell shortcut packing.
WorldSession gains SendAddShortcut / SendRemoveShortcut following the
SendChangeCombatMode sender pattern.

Port of gmToolbarUI::HandleSelectionChanged (acclient_2013_pseudo_c.txt:198635).
When the player selects a world object the action bar's bottom strip shows the
object name + (for player/pet/attackable targets) a live Health meter; deselect
clears it. Mana (#140) + stack slider deferred.
- SelectedObjectController (new): clear-then-populate on selection change; sets
name (UiText child, VitalsController pattern), overlay state (ObjectSelected /
StackedItemSelected via UiDatElement.ActiveState), shows the health meter and
sends QueryHealth for health targets. Subscribes via a delegate seam (no
GameWindow coupling).
- GameWindow: _selectedGuid field -> SelectedGuid property + SelectionChanged
event (fires on actual change only); 3 write sites converted, reads untouched.
All selection-write paths (LMB pick, Tab/Q, despawn-clear via Tick()) run on
the render thread, so the event-driven UI mutation is single-threaded.
- WorldSession.SendQueryHealth (0x01BF) — wraps SocialActions.BuildQueryHealth.
- DatWidgetFactory.BuildMeter: handle the single-image toolbar meter shape
(back-track on the element's own DirectState, fill on one Type-3 child). The
sprites go in the TILE slot (DrawMode=Normal tiles to full bar geometry per
UIElement_Meter::DrawChildren) — a left-cap assignment would gap/clamp a
sub-140px sprite. Vitals 3-slice path unchanged.
- ToolbarController.HiddenIds: A1 (health) now owned by SelectedObjectController;
A2 (mana) + A4 (stack) stay hidden (deferred) so their dat back-tracks don't
render as stray empty bars.
Adversarial Opus review found + fixed: the mana-meter orphan (A2 left unhidden)
and the meter tile-vs-cap render bug (C1). Divergence rows AP-46 (health gate
approximation: IsLiveCreatureTarget vs IsPlayer||pet||attackable) + AP-47
(meter shown on select vs on UpdateHealth reply). Spec §5 corrected.
Build + full test suite green (2,684 passed / 4 skipped). Health meter render
fidelity (full-width fill + fraction mapping) pending the user's visual gate.

The CreateObject optional-tail walker previously stopped at UseRadius (~20 fields
before IconOverlay). This left ItemInstance.IconOverlayId/IconUnderlayId always 0,
so IconComposer's underlay/overlay layers were never drawn on toolbar icons.
Exact field order verified against ACE WorldObject_Networking.cs:87-219 (the
serializer is the authority; acdream connects to a local ACE server):
UseRadius → TargetType(u32) → UiEffects(u32) → CombatUse(sbyte) →
Structure(u16) → MaxStructure(u16) → StackSize(u16) → MaxStackSize(u16) →
Container(u32) → Wielder(u32) → ValidLocations(u32) →
CurrentlyWieldedLocation(u32) → Priority(u32) → RadarBlipColor(u8) →
RadarBehavior(u8) → PScript(u16) → Workmanship(f32) → Burden(u16) →
Spell(u16) → HouseOwner(u32) → HouseRestrictions(variable RestrictionDB) →
HookItemTypes(u32) → Monarch(u32) → HookType(u16) →
IconOverlay(PackedDwordKnownType) ← CAPTURE →
IconUnderlay from weenieFlags2 bit 0x01 ← CAPTURE
RestrictionDB handled correctly: Version(u32) + OpenStatus(u32) + MonarchId(u32)
+ count(u16) + numBuckets(u16) + count×8 bytes entries. Length-aware skip, not a
fixed constant.
weenieFlags2 is now CAPTURED (not skipped) when IncludesSecondHeader
(objDescFlags bit 0x04000000) is set, so the IconUnderlay bit can be tested.
The entire extended walk is inside try/catch: truncated packets degrade to
IconOverlayId=0 / IconUnderlayId=0 (no overlay drawn), never corrupting.
Threading: CreateObject.Parsed → WorldSession.EntitySpawn → GameWindow
OnLiveEntitySpawned → Items.EnrichItem — both ids thread through all three
seams. EnrichItem extended with optional iconOverlayId + iconUnderlayId params
(defaulted 0, backward-compatible).
No change to IconComposer or ToolbarController (they already consume the ids).
Tests: 4 new CreateObject tests (IconOverlay only, overlay+underlay, no-overlay
regression, intermediate-fields cursor arithmetic). Full suite: 0 failures,
2636 passed.

Added uint IconId = 0 (defaulted, last positional param) to the EntitySpawn
record so existing call sites outside WorldSession compile unchanged. The
WorldSession invoke now passes parsed.Value.IconId as the final arg.
OnLiveEntitySpawned calls Items.EnrichItem unconditionally — it's a no-op
for non-item spawns (players/NPCs/furniture aren't in the repo), so the call
is safe for every incoming CreateObject.

Two retail divergences fixed end-to-end:
1. R-key Use on non-useable entities (signs, banners, decorative
scenery) was silently sending Use/PickUp to ACE, triggering
auto-walk + NPC-style chat fallback. Retail's client checks
ITEM_USEABLE (acclient.h:6478) and silently ignores Use when
the USEABLE_REMOTE (0x20) bit isn't set. Now ports that gate.
2. Holtburg town sign indicator + click sphere only covered the
base of the pole because the "everything else" default in
EntityHeightFor was 1.5 m and the picker's vertical offset
for default class was 0.2 m. A 3 m sign on a pole was almost
entirely outside both shapes.
Wire change:
- CreateObject parser now walks the WeenieHeader optional tail
(per ACE WorldObject_Networking.cs:87-114) up through Useability
+ UseRadius. Captures weenieFlags upfront, then conditionally
skips PluralName, ItemCapacity, ContainerCapacity, AmmoType,
Value before reading Useability (u32) and UseRadius (f32).
- CreateObject.Parsed + WorldSession.EntitySpawn record append two
new optional fields (Useability uint?, UseRadius float?), both
defaulting to null. Existing call sites unchanged.
- 3 new tests cover: no weenieFlags → null, weenieFlags=0x10 alone
→ useability read, weenieFlags=0x8|0x10|0x20 → walker skips Value
then reads Useability + UseRadius in correct order.
Behaviour change:
- GameWindow.IsUseableTarget(guid) — authoritative path uses spawn
.Useability when present (REMOTE bit gate); fallback when null
permits Use on creatures + BF_DOOR/LIFESTONE/PORTAL/CORPSE for
M1 flow continuity.
- UseCurrentSelection (R-key dispatcher) and SendUse + SendPickUp
(double-click + F-key direct paths) gate on IsUseableTarget,
silent early-return matching retail. isRetryAfterArrival skips
the gate (re-fires only previously-gated actions).
- TargetIndicatorPanel.EntityHeightFor default branch 1.5 m → 3 m
for non-creature non-flat non-small-item entities (sign-class).
Scale > 1 still grows proportionally.
- WorldPicker callbacks: new IsTallSceneryGuid branch lifts sphere
centre to 1.5 m with 1.6 m radius for sign-class entities,
mirroring the indicator's 3 m default so click sphere matches
the visible box.
Tests: 293/293 pass in AcDream.Core.Net.Tests (+3 new walker
tests). dotnet build clean.
Retail anchors:
- acclient.h:6478 — ITEM_USEABLE enum (USEABLE_REMOTE = 0x20)
- acclient.h:6431-6463 — PWD bitfield (BF_DOOR etc.)
- ACE WorldObject_Networking.cs:87-114 — wire field order
- ACE WeenieHeaderFlag — Usable = 0x10, UseRadius = 0x20

After B.5 shipped, the actual pickup was invisible feedback-wise: the
item left the ground, ACE despawned it via PickupEvent (0xF74A), and
the ItemRepository got updated — but the player had no visual
acknowledgement that anything happened. The M1 demo's "pick up an
item" target visually felt like the item just vanished into the void.
Add a new EntityPickedUp event to WorldSession that fires from the
PickupEvent (0xF74A) dispatch branch BEFORE EntityDeleted, so the
subscriber can still read the entity's display name from
_entitiesByServerGuid before the despawn handler clears it.
GameWindow subscribes during the live-session wiring block and emits
a retail-style system chat line plus a debug toast on every successful
pickup, mirroring retail behavior (retail synthesized this line
client-side; ACE doesn't echo it).
Closes the M1 demo "pick up" target's visible-payoff gap.
ACE sends GameMessagePickupEvent (opcode 0xF74A) instead of
GameMessageDeleteObject (0xF747) for items removed via player pickup
(Player_Tracking.RemoveTrackedObject with fromPickup=true).
Without this handler, BuildPickUp succeeded server-side (item moved
into the player's container, retail observers saw it disappear), but
our local client kept rendering it on the ground because the despawn
message went to the unhandled-opcode bucket.
PickupEvent's wire body adds an objectPositionSequence field on top
of DeleteObject's layout, so the parser is its own type. The
downstream view-removal semantics are identical to DeleteObject, so
the dispatcher routes both opcodes into the same EntityDeleted event
via a small adapter.
Three changes folded into one commit:
1. New public StateUpdated event on WorldSession + dispatcher branch
for op == SetState.Opcode. Mirrors the VectorUpdated /
MotionUpdated event pattern. GameWindow will subscribe in the next
commit and feed the parsed (guid, newState) pair to
ShadowObjectRegistry.UpdatePhysicsState.
2. One-shot probe-gated hex-dump (ACDREAM_PROBE_BUILDING) emits the
first inbound SetState message's body bytes. Originally planned
as a separate slice 1.5 confidence-check on holtburger's claimed
12-byte payload vs ACE's GameMessageSetState.cs. Folded into the
dispatcher to avoid re-touching the same branch. The new
_setStateHexDumped guard keeps the log clean — auto-close every
30s would otherwise produce noise.
3. Doc-comment polish on SetState.cs requested by Task 1's code
review: remove false uncertainty about ACE's sequence-field width
(ACE's UShortSequence.CurrentBytes provably writes 2 bytes via
BitConverter), and align the 'total body size' phrasing with
VectorUpdate.cs's convention. Folded here to avoid churning the
file twice this slice.
