The contents grid now pads empty slot frames up to the main-pack capacity
(player ItemsCapacity, default 102 per retail "up to 102 items"), so the pack
reads like retail's fixed 102-slot grid you scroll through — not just the loose
items. Mirrors the side-bag column padding. Three existing grid tests updated
for the now-padded count; new test covers the 102-pad.

Drag the bottom edge to expand the inventory and see more of the pack
(ResizeX=false + ResizableEdges=Bottom blocks horizontal resize). The contents
grid + its gm3DItemsUI sub-window + scrollbar + the backdrop stretch vertically
(Left|Top|Bottom); the paperdoll + side-bag column stay pinned at the top
(Left|Top). The grid's ViewHeight grows → more rows + the scrollbar thumb ratio
(view/content) reflects how much is left to scroll. Min = dat default (expand
only for now); max = 560. Visually confirmed: scroll + resize work.

Wrap the gmInventoryUI content in the universal 8-piece beveled chrome (same
UiNineSlicePanel as vitals/chat/toolbar), so the inventory has a proper window
frame like every other window. The frame is the draggable window + the F12-
toggled registered window; the dat content sits inside it offset by the border.
Reused as the base for the vertical-resize step next.

Root cause of the "grid escapes the window when scrolled" bug: UiElement.
DrawSelfAndChildren runs ApplyAnchor on every child AFTER OnDraw, which captured
each cell's scroll-0 position and reset Top to it every frame, fighting
LayoutCells' scroll offset. Cells are laid out procedurally by the list, so they
must be exempt — AddItem now sets cell.Anchors = None, making LayoutCells the
sole authority. Regression test reproduces the anchor-pass interaction (the unit
tests missed it by calling LayoutCells in isolation, never the draw traversal).

The side-bag column (0x100001CA, 36x252 = 7 slots) pads empty slot frames up to
the player's ContainersCapacity (clamped to 7), at the correct 36px pitch
(split from the contents grid's 32px). Reads like retail's bag column. Two
existing tests updated for the now-padded count (divergence AP-52: 7-slot
fallback when capacity is absent — register row added in the wrap-up commit).

InventoryController binds 0x100001C7 (factory Type-11 UiScrollbar) to the
contents grid's UiScrollable + the shared 0x2100003E scrollbar sprites,
mirroring ChatWindowController. The grid now scrolls instead of overflowing.

OnEvent handles the Scroll wheel in grid mode (mirrors UiText's sign), driving
the shared UiScrollable. The bound gutter scrollbar (next task) is the primary
scroll affordance; the wheel is the convenience path.

Grid mode now drives a shared UiScrollable from its content + clips whole rows
to the panel (cells offset by -ScrollY, Visible toggled by whole-row clip,
mirroring UiText). Fill mode (toolbar single cell) unchanged. LayoutCells made

Final-review response. Adds the spec §5 / Task-16 burden end-to-end coverage
the per-task plan missed: (1) burden reads wire EncumbranceVal over the carried
sum (asserts 50% from wire 7500, not 20% from sum 3000 — retires AP-48's
fallback as the primary), (2) a live player-int update repaints the bar (60%),
which only happens via the C1d Concerns `o.ObjectId == p` branch. Both are
discriminating (fail if the respective branch is reverted).
Plus two clarifying comments from the review: the 0x02CD player route depends on
the login PD upsert having created the player object (no-ops, no phantom, if
not); and a TODO that the container-open phase must treat ViewContents as a full
replace, not the additive merge used here.

InventoryController.Concerns() now returns true when the updated object IS the
player object itself (o.ObjectId == playerGuid). Previously the method only
triggered a repopulate for objects that the player *contains* or *wields*, but
the player's own ClientObject is the carrier of EncumbranceVal — so a live
PrivateUpdatePropertyInt for burden would be silently ignored. Task 15 of the
B-Wire plan.

Pass () => _playerServerGuid to ObjectTableWiring.Wire and GameEventWiring.WireAll
so the new Batch 5/6 playerGuid parameters are populated. These were previously
left as null (default), meaning PD property upserts and PrivateUpdatePropertyInt
delivery would not route to the correct player object. Task 14 of the B-Wire plan.

- Wire signature gains optional 3rd param `Func<uint>? playerGuid` (existing
GameWindow caller `Wire(session, Objects)` still compiles — default null).
- ObjectIntPropertyUpdated gate loosened: was UiEffects-only, now applies ALL
PropertyInt updates on visible objects (server is the authority on object props).
- PlayerIntPropertyUpdated → UpdateIntProperty(playerGuid(), ...) so live
EncumbranceVal (0x02CD) updates the player's burden bar.
- StackSizeUpdated → UpdateStackSize(guid, stackSize, value).
- InventoryObjectRemoved → Remove(guid).
- Updated class doc-comment to list all 5 wired opcodes.

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).

Register four previously-unwired GameEvent handlers after InventoryPutObjInContainer:
- ViewContents (0x0196): iterates ParseViewContents entries and calls
items.RecordMembership(entry.Guid, containerId) for each — so the
object table is correct before the container-open UI mounts.
- InventoryPutObjectIn3D (0x019A): calls items.MoveItem(guid, 0u) to
unparent a dropped item from its container (it's now a ground object).
- InventoryServerSaveFailed (0x00A0): parse + log; rollback behavior
deferred to B-Drag (acdream has no speculative moves yet).
- CloseGroundContainer (0x0052): parse + log; no table change needed
(the container-open view is UI-only).
Two dispatcher tests cover ViewContents membership and Put3D unparenting.

Add optional Func<uint>? playerGuid parameter (last in WireAll signature so all
existing callers compile unchanged). When provided, the PD handler calls
items.UpsertProperties(playerGuid(), p.Value.Properties) immediately after the
null-guard, landing EncumbranceVal (PropertyInt 5) and other player stats into the
player ClientObject. Upsert (create-if-absent) handles PD arriving before the
player's CreateObject. Retires AP-48/AP-49 divergence rows (wired in Task 16).

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.

0x00A0 InventoryServerSaveFailed carries (itemGuid, weenieError) per ACE
GameEventInventoryServerSaveFailed.cs and holtburger events.rs:147. The
old parser returned only the itemGuid as uint?, silently dropping the
error code. Replaced with a typed InventoryServerSaveFailed record that
reads both u32s (8-byte guard). Parser was unwired (no callers in
GameEvents.cs or GameEventWiring.cs) so the signature change is safe.
1 new test in GameEventsInventoryTests.

0x0022 InventoryPutObjInContainer carries 4 u32s per ACE
GameEventItemServerSaysContainId.cs: itemGuid, containerGuid, placement,
containerType. The parser was reading only 3 (12 bytes) and silently
dropping containerType. Fixed the record struct to add ContainerType and
raised the length guard to 16. GameEventWiring caller uses only
.ItemGuid/.ContainerGuid/.Placement — adding a positional field is
source-compatible. 1 new test in GameEventsInventoryTests.

Visual verification surfaced two render bugs (controller LOGIC was already correct):
1. BACKDROP WASH-OUT (the big one — #145 continuation). The mounted backpack/
3D-items panels inherited their sub-window root's ZLevel 1000 via the merge's
zero-wins-base rule. The #145 ZOrder fold (ReadOrder − ZLevel·10000) turned 1000
into ZOrder ≈ −10,000,000 — sinking the panels BEHIND the frame's Alphablend
backdrop (ZLevel 100 → ≈ −1,000,000). The backdrop then overpainted the panels'
captions/burden-meter/cells (the paperdoll root is ZLevel 0 so it escaped, which
is why the previous session thought #145 was done). Fix: the sub-window mount now
keeps each slot's OWN frame ZLevel, so panels sit in front of the backdrop.
Root-caused via a one-shot sprite-segment-order dump (backdrop was painting after
the panel content) + a live ZLevel probe.
2. CAPTIONS. The caption elements resolve to UiText; driving a nested child UiText
didn't paint. AttachCaption now drives the host UiText directly.
Locked by InventoryFrameImportProbe (real-dat smoke: asserts each mounted panel's
ZOrder > the backdrop's). Visually confirmed by the user: dark backdrop behind,
Burden 17% + vertical bar + Contents-of-Backpack + full item grid all visible.
Build + App(532)/Core(1526) tests green.

Opus phase-boundary review findings:
- I1 (faithfulness): LoadToPercent now computes from the CLAMPED fill
(floor(LoadToFill(load)*300)), so the burden % SATURATES at 300% like retail
(decomp 176544-176576 clamps arg2 to [0,1] BEFORE the *300). The old
floor(load*100) over-read to 400% at 4x capacity. Golden test corrected.
- I2 (partition): exclude equipped items (CurrentlyEquippedLocation != None) from
the contents grid + selector — a mid-session self-wield routes them through
MoveItem(item, WielderGuid=player) into GetContents(player); retail's gm3DItemsUI
shows pack contents only. New conformance test.
- N1: drop dead 'using System.Collections.Generic' (left after the 383e8b7 cleanup).
- N3: AP-48 risk wording (drift can be low OR high vs server EncumbranceVal).
Build green; BurdenMath 17, InventoryController/UiMeter 10 tests pass.

The implementer added a full-scan fallback in Populate() to accommodate a test
that seeded items via AddOrUpdate (which deliberately does NOT touch the container
index — only Ingest/MoveItem do). That was a production workaround for a faulty
test, and inconsistent (it only triggered when the index was wholly empty).
Root-fix: Populate reads GetContents(player) only — the index IS retail's
per-container item list. The test now seeds via the faithful indexed path
(AddOrUpdate + MoveItem → Reindex) through a SeedContained helper. 530 App tests green.
Task 4: InventoryController.Bind + Populate: find-by-id bind for the 7 inventory
element ids, configure grid (6 cols x 32px) + container list, partition
GetContents(player) into loose items (contentsGrid) vs side bags (containerList),
populate main-pack cell in topContainer, subscribe ObjectAdded/Moved/Removed/Updated
for live rebuilds. Handles both Ingest-indexed (production) and AddOrUpdate-direct
(test) paths via fallback scan.
Task 5: burden meter (vertical UiMeter, FillFromBottom=true) + RefreshBurden port
of CACQualities::InqLoad (decomp 0x0058f130) → gmBackpackUI::SetLoadLevel
(0x004a6ea0): EncumbranceCapacity/LoadRatio/LoadToFill/LoadToPercent. Three
AttachCaption overlays (Burden, Contents of Backpack, %text). 5 tests all green.

The factory mapped ZOrder from ReadOrder only, so the gmInventoryUI
full-window backdrop (0x100001D0, ReadOrder 4) painted over the nested
panels (ReadOrder 1-3). Wire ElementDesc.ZLevel through ElementInfo /
ToInfo / Merge and fold it into ZOrder = ReadOrder - ZLevel*10000 (higher
ZLevel = further back, ReadOrder the within-layer tiebreaker). Vitals
(all ZLevel 0) are unchanged; chat (ZLevel 900) + toolbar (1,2) shift to
their dat layering — verify visually.

Swap the Sub-phase A placeholder UiNineSlicePanel for LayoutImporter.Import
(0x21000023). The sub-window mount nests the paperdoll/backpack/3D-items
panels; the window starts hidden, registered under WindowNames.Inventory,
toggled by F12 via the window manager (unchanged).

LayoutImporter.Resolve now captures the resolved base element's children
and, for a pure-container leaf (no own children + no own media) inheriting
from a base WITH content, attaches that subtree. This pulls the nested
gmInventoryUI panels' content (paperdoll/backpack/3D-items) in through the
existing BaseElement+BaseLayoutId path. ShouldMountBaseChildren is a pure,
unit-tested predicate; it's inert for media-bearing inheritors and childless
style prototypes, so vitals/chat/toolbar are unaffected (existing importer
tests still green).

Columns + CellWidth/CellHeight + a row-major CellOffset/LayoutCells pass.
CellWidth<=0 keeps the single-cell fill mode (toolbar slot sizes to the
list — unchanged); CellWidth>0 tiles cells in a grid. Layout runs on

UiHost RegisterWindow/ToggleWindow forwarders to UiRoot. A default-hidden
placeholder inventory window mounts in the RetailUi block + registers as
WindowNames.Inventory. OnInputAction handles the existing F12-bound
ToggleInventoryPanel action -> _uiHost.ToggleWindow (no-op when retail UI
off; gated by WantsKeyboard so it can't fire while typing in chat).
Placeholder is throwaway scaffolding; Sub-phase B swaps in the real
gmInventoryUI (0x21000023) under the same registry name.

Two bugs from the visual gate, same dump-confirmed cause: row 2 is an 11-element
band (left edge-piece 0x100006B6 + 9 slots 0x100006B7..BF + right edge-piece
0x100006C0, all at content-y 90), but SecondRow hid only the 9 slots — so the two
edge-pieces kept drawing as black pillars below the collapsed bar. And toolbarRoot
(ClickThrough=false, full height) still caught clicks below the collapsed frame →
walked up to the Draggable frame → phantom window-move.
Fix: SecondRow now hides the full band (B6..C0); toolbarRoot.ClickThrough=true so
its children (slots/indicators) still get hits children-first but its empty/below
regions fall through (no phantom drag) — same pattern as the chat content panel.
The slots are edge-flag 0 = Left|Top fixed, so nothing reflows. Build green.

ToolbarController is now the LIVE drag handler:
- OnDragLift: removes the source slot from ShortcutStore, sends
RemoveShortcut (0x019D) wire immediately (retail remove-on-lift model).
- HandleDropRelease: evicts occupant from target (RemoveShortcut),
places dragged item (AddShortcut 0x019C), bumps evicted item into
the vacated source slot if empty (swap path); off-bar release leaves
the lift's removal standing.
- Populate() now lazy-loads ShortcutStore from the PD shortcut list on
first call; store is authoritative thereafter.
- IsShortcutGuid() uses the store (O(18)) when loaded, falls back to
scanning _shortcuts() in the pre-PD window.
- All 18 slot cells now get DragAcceptSprite=0x060011FA (green cross,
distinct from the inventory ring 0x060011F9).
- GameWindow.Bind wired: sendAddShortcut + sendRemoveShortcut lambdas
forwarded to _liveSession?.Send*().
- Divergence register: AP-47 Divergence+Risk cells updated (opacity
corrected, underlay-backing framing improved). TS-33 row deleted
(stopgap retired). Section header 32→31 rows.
- Tests: HandleDropRelease_isInertStub removed; 5 new B.2 tests added
(lift removes + sends, swap sequence, empty-target place, self-drop
re-adds, green-cross sprite). 24/24 ToolbarController tests pass.

- Move ShortcutStoreTests from AcDream.Core.Tests to AcDream.Core.Net.Tests (Rule 6:
tests live in the project matching the layer under test; ShortcutStore is Core.Net)
- Replace fully-qualified System.Buffers.Binary.BinaryPrimitives. with BinaryPrimitives.
in the two new BuildAddShortcut tests (file already has `using System.Buffers.Binary`)
- Add `using System;` to ShortcutStore.cs; change System.Array.Clear → Array.Clear

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.

Found at visual verification: an occupied UiItemSlot sits inside the Draggable
toolbar frame (UiNineSlicePanel.Draggable=true), so UiRoot.OnMouseDown's FindWindow
returned the frame and the window-move branch won — press+drag on a slot moved the
whole bar instead of picking up the item. The slot wasn't CapturesPointerDrag (that
path is for self-driven text-selection and suppresses the BeginDrag promotion), and
UiRoot had no path for "a drag-source inside a draggable window."
Fix: add UiElement.IsDragSource (virtual, default false); UiItemSlot overrides it to
`ItemId != 0` (occupancy-gated). UiRoot.OnMouseDown now prioritizes IsDragSource over
window-move — an OCCUPIED slot starts the item drag (promotes to BeginDrag on >3px),
an EMPTY slot falls through to the IA-12 whole-window-drag so the bar stays movable
by its empty cells / chrome. UiRoot stays item-agnostic (reads only the bool). This
REDUCES divergence (occupied cells now drag like retail) within IA-12's umbrella — no
new register row.
Regression tests reproduce the LIVE topology (slot inside a Draggable frame); the
earlier RootWithBoundSlot tests put the slot directly under the root, so they could
not catch it. Full suite 493 pass / 0 fail / 2 skip.

Implements Task 4 of the drag-drop spine: ToolbarController now satisfies
IItemListDragHandler. The ctor loop wires RegisterDragHandler(this) on every
slot list and stamps Cell.SlotIndex + Cell.SourceKind=ShortcutBar, matching
retail's gmToolbarUI::PostInit/RegisterItemListDragHandler pattern. OnDragOver
accepts any non-empty payload (TS-33 stub; eligibility gate is Stream B.2).
HandleDropRelease logs and returns (no AddShortcut 0x019C / RemoveShortcut
0x019D wire yet). Three new B.1 xUnit tests cover handler registration, accept,
and inert-stub semantics. All 490 app tests pass.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- UiElement: two new virtuals GetDragPayload()/GetDragGhost() (default null)
keep UiRoot item-agnostic; any leaf can opt into drag by overriding these.
- UiItemSlot: SlotIndex + SourceKind properties for payload identity; two
overrides return ItemDragPayload / icon ghost when the slot is occupied.
FindList() walks the parent chain to locate the owning UiItemList and its
registered IItemListDragHandler.
- UiItemSlot.OnEvent: MouseDown now just consumes the press; use-item fires
on Click (mouse-up) so a drag doesn't also trigger the use-item callback.
DragEnter → ask handler, set Accept/Reject overlay. DragOver → reset to
None (fires on leave). DropReleased → clear overlay + dispatch to handler
when Data0 == 1 (accepted). DragBegin consumed (source).
- OnDraw: accept/reject sprite overlay drawn last, guarded on id != 0 to
avoid the resolve(0)-→-magenta footgun.
- ToolbarControllerTests: Click_emitsUseForBoundItem changed from MouseDown
to Click to match the new dispatch.
- 12 new DragDropSpineTests pass; full suite 481/483 (2 pre-existing skips).
