Sub-phase C, Slice 1 — bind the ~25 paperdoll equip slots to live
equipped-item data + make them drag-drop wield/unwield targets. No 3D
doll (that's Slice 2).
Brainstorm findings baked in:
- The handoff's "build the wire gap" premise is STALE: BuildGetAndWieldItem
+ SendGetAndWieldItem already shipped in B-Wire. The whole optimistic-move
machine + InventoryController:IItemListDragHandler already exist — Slice 1
mirrors them. Unwield is free (the inventory grid handler already does it).
- Found a latent bug: acdream's EquipMask enum diverges from canonical AC
(acclient.h:3193 INVENTORY_LOC) from bit 0x2000 up (phantom HandArmor/
FootArmor). Correct it to the verbatim retail values + a numeric-pin test.
Blast radius is safe (4 round-trip test refs).
- Empty equip slots are TRANSPARENT (EmptySprite=0), per the user — faithful,
zero Slice-2 rework.
Real scope: correct EquipMask (Core) + WieldItemOptimistic & equip-aware
rollback snapshot (Core) + ConfirmMove on the WieldObject 0x0023 handler
(Core.Net) + PaperdollController (App) + GameWindow wiring. Element-id→mask
map verified dump ↔ deep-dive §3a ↔ acclient.h.

Detailed handoff for the next session. Key correction from the deep-dive:
retail empty equip slots are TRANSPARENT (the doll shows through), NOT
silhouettes — the current blue border is wrong. Decomposes into Slice 1
(equip slots: bind to CurrentlyEquippedLocation + drag-to-wield via the
GetAndWieldItem 0x001A wire gap) and Slice 2 (the heavy 3D doll UiViewport
Type 0xD + Core->App IUiViewportRenderer seam). Maps the reuse surface
(UiItemSlot, drag spine, optimistic-move, EntitySpawnAdapter) + open
questions + a paste-ready new-session prompt.

Visual gate: moving an item within a bag reshuffled every item ("the order is
not set"). Root cause: insert-before set ONLY the dragged item's ContainerSlot
to N, colliding with the item already at N; the sort-by-slot tie then reordered
the whole grid on every repaint. Fix: MoveItemOptimistic now does a proper
index-based INSERT (shift the others, renumber 0..N-1 gapless) like retail's
ItemList_InsertItem, and HandleDropRelease uses the target's GRID INDEX
(SlotIndex) as the placement rather than its raw ContainerSlot. Regression test
pins the shifted, gapless order. Full suite green.

I2 (real bug): Clear() (teleport/logoff) and Remove() (item destroyed) now drop
the item's _pendingMoves entry — a stale snapshot on a recycled guid could
otherwise mis-rollback a different future item.
I1 (race): track an OUTSTANDING count per item so an early ConfirmMove (0x0022)
for the first of several in-flight moves of the SAME item can't clear the
snapshot while a later move is unconfirmed — a later reject can still roll back
to the original instead of stranding the item at the rejected position.
Both with regression tests; full suite green.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add the 3 tests the spec-compliance review flagged: 0x0022 ConfirmMove clears
the pending move (no rollback after a confirm); OnDragOver advisory-accepts a
closed bag (cap>0, contents not indexed = AP-61); App-level drop -> RollbackMove
reverts the optimistic move to the original container+slot. Production code was
already correct; these exercise the spec's test plan.

Brainstorm output for B-Drag. Drop an inventory item: empty grid slot ->
first empty; on an item -> insert before; on a side-bag cell -> into that
container. Green insert-arrow (valid) / red circle (full). Movement is
OPTIMISTIC/instant per the user — local MoveItem on drop + repaint, server
reconciles via 0x0022 echo, rolls back via 0x00A0 (the rollback the B-Wire
note reserved). InventoryController : IItemListDragHandler; pending-move
tracking in ClientObjectTable (Core, reachable from the Core.Net handlers);
SendPutItemInContainer wraps BuildPickUp 0x0019. Retail anchors: InqDropIconInfo
0x004e26f0 / ItemList_InsertItem / HandleDropRelease / ServerSaysMoveItem.

Faithful port of retail UIElement_UIItem::UpdateCapacityDisplay (0x004e16e0):
each container cell (side bags + main pack) shows a vertical UIElement_Meter
(element 0x10000347, back 0x06004D22 / fill 0x06004D23) filled to
GetNumContainedItems / ItemsCapacity, clamped [0,1]; hidden for non-containers
(CapacityFill=-1). Drawn procedurally on UiItemSlot like the triangle/square
overlays (back full + front clipped bottom-up). Right-anchored flush to the cell
edge (visual gate: the dat X=26 sat ~5px off the right edge). Visually confirmed
2026-06-22. Divergence AP-59; polish deferred to ISSUES #146 (exact rect/anchor,
fill direction vs m_eDirection 0x6f, closed-bag lazy-load).

The prior commit pinned 0x060011F4 from a research dat-dump of
GetDIDByEnum(0x10000004,7) — it rendered as a GREEN TILE (green slot, no
pack) at the visual gate. Dat-exported the candidates (AcDream.Cli
dump-sprite-sheet / export-ui-sprite): 0x0600127E is the 32x32 brown
backpack (user-hinted, PNG-confirmed). Swap the pinned literal; the
test + AP-51 register row updated to the visually-verified id. Container
type-underlay (green) + backpack base still composited via _iconIds.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The m_topContainer cell (0x100001C9) rendered blank (tex=0). Retail's
IconData::RenderIcons (0x0058d1ee) has an IsThePlayer() branch that draws a
CONSTANT backpack — m_idIcon = GetDIDByEnum(0x10000004, 7) = 0x060011F4,
m_itemType = TYPE_CONTAINER — NOT the player's body icon (the original AP-51
"equipped-pack weenie icon" premise was wrong). Compose that base over the
Container type-underlay via the existing _iconIds delegate. Verified vs decomp
(407546-407549) + IconComposer.GetIcon (base=arg2, type drives underlay) + a
live dat dump (map 0x25000008 index 7 = 0x060011F4). Test locks type+literal.
AP-51 reworded to the residual hardcoded-vs-runtime-resolve nuance (cf. AP-55).

Comment-only. (1) the InventoryController summary said "Read-only: no
container switching" — now live. (2) note the _openContainer 0-vs-playerGuid
sentinel equivalence so the dual main-pack path isn't mistaken for dead code.
No behavior change. Code-quality review verdict: APPROVED (ship to gate).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Brainstorm output for inventory container-switching. Key decision from
the brainstorm: the handoff conflated two orthogonal retail mechanisms —
the open-container TRIANGLE (0x06005D9C, UpdateOpenContainerIndicator) and
the selected-item SQUARE (0x06004D21, ItemList_SetSelectedItem). User
confirmed both are real (a bag is just an item, so it gets the square too)
and chose to ship both this phase, the square uniform across grid+bags and
visual-only (no selected-object-bar wiring yet).
Pins the ViewContents full-REPLACE (ACE writes entries OrderBy
PlacementPosition, no slot field -> ContainerSlot=index), the Use 0x0036 ->
ViewContents 0x0196 round-trip, and the 6 touched files.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Banks the next clean inventory win (container-switching: Use 0x0036 -> ViewContents
0x0196 full-replace + the selected-container indicator that retires AP-56) as a
handoff for a fresh session, per the late-session-handoff lesson. Wire layer
already exists; design sketch + open questions captured.
Also flags the CLAUDE.md "Current state" banner as stale — it still tracks M1.5
(indoor world, 2026-06-14) while the active stream has been the D.2b retail-UI
track for weeks. Left the milestone reframing for a fresh reconciliation against
the milestones doc rather than a tired guess.

User confirmed the container column reads correct after the inheritance-resolved
fix (22d9231). Status: inventory empty-slot art FIXED + VISUALLY CONFIRMED.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Visual gate (2026-06-22) showed the side-bag/main-pack empty cells drawing yellow
triangles. Root cause: the frame-first heuristic grabbed the 36x36 container
prototype's DirectState child 0x06005D9C — which is the open/SELECTED-container
triangle indicator, NOT a background frame — and stamped it onto every empty cell.
Fix: drop frame-first; FindIconEmpty resolves the inner m_elem_Icon ItemSlot_Empty
THROUGH BaseElement inheritance (0x1000033F -> 0x10000340 -> base 0x1000033E ->
0x1000033B -> 0x06000F6E), so containers get the dark slot background matching the
inventory. Pin test now asserts exact ids (0x06004D20 contents / 0x06000F6E
containers) — the old structural-only assertion let the wrong-but-valid 0x06005D9C
pass (Opus review Minor 2, now vindicated). The triangle + green/yellow selection
square is deferred to container-switching (AP-56 reworded). Full suite green.

Inventory contents grid / side-bag / main-pack empty cells now dat-resolve their
art via ItemListCellTemplate (0x1000000e -> 0x21000037). Paperdoll equip
silhouettes + main-pack icon remain open (Sub-phase C / AP-51).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Inventory contents grid / side-bag / main-pack cells now render the retail
pack-slot empty art (dat cell template via ItemListCellTemplate) instead of the
generic toolbar square. Divergence rows AP-55 (toolbar still hardcoded) + AP-56
(flat single-sprite cell vs retail''s layered prototype).

Ports UIElement_ItemList::InternalCreateItem (0x004e3570) attribute lookup to a
testable static helper. The 0x1000000e property is an EnumBaseProperty (not
DataIdBaseProperty as the spec anticipated) — discovered by runtime reflection and
confirmed against the live dat. Pinned sprite ids from real-dat test:
contents (0x100001C6): 0x06004D20
side-bag (0x100001CA): 0x06005D9C
main-pack (0x100001C9): 0x06005D9C

5-task TDD plan for the OPEN empty-slot-art issue: ItemListCellTemplate resolver
(ports UIElement_ItemList::InternalCreateItem's 0x1000000e -> 0x21000037 lookup),
UiItemList.CellEmptySprite, InventoryController + GameWindow wiring, divergence
rows AP-55/AP-56, ISSUES close + visual gate. Each task is test-first with exact
code; Task 1 pins the exact retail sprites from the live dat.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Brainstorm + decomp investigation for the OPEN issue "Inventory + equipment
slots show the wrong empty-slot background art". Verified against the named
decomp that retail's UIElement_ItemList::InternalCreateItem (004e3570) sources
each list's empty-cell sprite from attribute 0x1000000e on the list's own
ElementDesc -> catalog LayoutDesc 0x21000037 -> the prototype's ItemSlot_Empty
(0x1000001c) media. acdream hardcodes 0x060074CF (the generic toolbar square),
bypassing the per-list cell-template inheritance entirely.
Design ports the resolver: a new ItemListCellTemplate.ResolveEmptySprite helper
(mirrors the existing GameWindow 0x21000037 digit-array read), a
UiItemList.CellEmptySprite property, and InventoryController wiring for the
contents grid / side-bag / main-pack lists. Toolbar untouched (its 0x060074CF
is correct); paperdoll silhouettes stay Sub-phase C.

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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
internal for tests; RowCount helper added.

6 tasks: (1) UiItemList clip+scroll via the shared UiScrollable + whole-row
clip; (2) mouse-wheel; (3) InventoryController binds the gutter scrollbar
0x100001C7 like ChatWindowController; (4) side-bag column 36px pitch + empty-
slot padding to capacity; (5) backdrop coverage — screenshot-gated, primary
fix is the clip; (6) verify + bookkeeping. TDD on the pure/controller logic
(internals test-visible); backdrop is the visual gate. Grounded in the dat
dumps + the existing scroll/scrollbar machinery.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Stage 1 of the "full retail inventory" arc (Stage 2 = paperdoll, separate
spec). Grounded in the dat dumps: contents grid 0x100001C6 is 192x96 (6x3) +
scrollbar 0x100001C7 (16x96); backdrop 0x100001D0 is full-window 300x362
(so the "torn" look is the unclipped grid overflowing below the frame —
fixed by clipping); side-bag column 0x100001CA is 36x252 (7 slots).
Components: (A) UiItemList clip+scroll reusing UiScrollable + bind the gutter
scrollbar like ChatWindowController; (B) backdrop coverage — primary fix is A,
residual gated on the post-A screenshot; (C) side-bag column pads empty slots
up to capacity at 36px pitch. Paperdoll + B-Drag out of scope.

Reword AP-48 (burden) and AP-49 (carry-aug) to fallback/default-only: B-Wire
ports the retail wire read (login PD-bundle UpsertProperties + live 0x02CD;
ObjectTableWiring applies all ints), so SumCarriedBurden / aug=0 are now
defensive only. Confirm the server sends EncumbranceVal/0xE6 at the visual
gate, then delete the rows. Add the D.2b-B B-Wire SHIPPED entry to ISSUES.
(Memory digest project_d2b_retail_ui.md + MEMORY.md updated out-of-tree.)
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
