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).

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).

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

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.

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>
Design/spec for B-Wire (follows B-Controller c38f098). Root cause found:
the burden binding already reads wire EncumbranceVal (PropertyInt 5) but
the value never arrives — login PD parses the player's int table then
drops it, the live 0x02CD (PrivateUpdatePropertyInt, no guid) is unparsed,
and ObjectTableWiring gates all non-UiEffects ints out.
Scope (user chose the full wire pass): player-property delivery (login PD
bundle upsert + 0x02CD parse + loosen the apply gate, retiring AP-48/AP-49),
latent-bug fixes (0x0022 4th field, 0x00A0 error), new C→S builders
(DropItem 0x001B / GetAndWieldItem 0x001A / NoLongerViewingContents 0x0195),
new S→C parsers (ViewContents 0x0196 GameEvent; SetStackSize 0x0197 +
InventoryRemoveObject 0x0024 GameMessages), and WireAll registration.
Opcodes pinned against ACE GameMessageOpcode.cs / GameActionType.cs; every
format requires grep-named → cross-ref → pseudocode → port + conformance.

- #145: the original fix was incomplete (mounted panels inherited ZLevel 1000 →
behind the backdrop → washed out); continuation 417b137 closes it. Updated status.
- D.2b-B SHIPPED entry: visually confirmed; the two render bugs (backdrop wash-out
+ captions host-direct) documented.
- New OPEN issue: contents grid overflows (needs the gutter scrollbar wired; scroll
was out-of-scope for B-Controller per the spec).
- Roadmap ledger: B-Controller visually confirmed + the render fix noted.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Read-only population of the gmInventoryUI tree: bind 0x21000023 by id,
fill the 'Contents of Backpack' grid + the right-strip pack-selector from
ClientObjectTable, drive the vertical burden meter, render the Type-0
captions. Faithful selector + full faithful burden meter (per brainstorm).
Ported AC algorithms with decomp anchors: CACQualities::InqLoad (0x0058f130),
EncumbranceSystem::EncumbranceCapacity (0x004fcc00) / Load (0x004fcc40),
gmBackpackUI::SetLoadLevel (0x004a6ea0), UIElement_Meter::DrawChildren
(0x0046fbd0) / Initialize (0x0046f7b0, m_eDirection from property 0x6f).
Key finding: BuildMeter's single-image sprite assignment is already correct
(meter-own=track, child=fill); only vertical fill is new.

B-Grid sub-window mount works (paperdoll base 0x100001D4 has 25+ equip-slot
children, attached), but the gmInventoryUI panels render blank: the
importer maps ZOrder from ReadOrder only, so the full-window backdrop
(0x100001D0, ReadOrder 4) paints over the panels (ReadOrder 1-3). Retail
keeps it behind via ZLevel (backdrop 100 vs panels 0), which the importer
ignores (vitals were all ZLevel 0). Fix scoped in the issue.

4-task TDD plan: UiItemList grid mode (CellOffset/Columns/cell pitch),
the LayoutImporter.Resolve sub-window mount (ShouldMountBaseChildren +

First step of Sub-phase B (inventory window). Dumped LayoutDesc 0x21000023:
the three nested panels (paperdoll/backpack/3D-items) are Type-0 pure-
container leaves that nest via the EXISTING BaseElement+BaseLayoutId
inheritance path (BaseLayoutId → 0x21000024/22/21), NOT game-class Types as
the research agent claimed. ElementReader.Merge drops base children, so they
import empty today. Mount = a surgical ~4-line LayoutImporter.Resolve change:
a childless, media-less inheritor attaches its base's resolved subtree
(predicate ShouldMountBaseChildren, unit-testable; inert for media-bearing
inheritors + childless style prototypes, so vitals/chat/toolbar are
unaffected). Plus UiItemList N-cell grid mode (single-cell toolbar preserved).

The UiRoot window manager (RegisterWindow/Show/Hide/Toggle/BringToFront)
is more of the same IA-12 toolkit-reimplementation of keystone semantics,
so per the dedup convention it joins IA-12's Where as a secondary site
rather than getting a redundant row. F12 inventory toggle is retail-
faithful (no divergence).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
4-task TDD plan for Sub-phase A: UiRoot named-window registry
(Show/Hide/Toggle/BringToFront) + raise-on-click + F12 wiring of the
existing ToggleInventoryPanel action to a throwaway placeholder inventory

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Sub-phase A of the window-manager → inventory → paperdoll arc. A named-
window registry on UiRoot (Show/Hide/Toggle/BringToFront) + raise-on-click
+ wiring the EXISTING InputAction.ToggleInventoryPanel (already F12-bound,
retail-faithful) through OnInputAction, toggling a throwaway placeholder
inventory window that Sub-phase B replaces with the real gmInventoryUI.
Cross-check correction vs the handoff: retail's inventory key is F12, not
I (I = Laugh emote per retail-default.keymap.txt:246). Reuses the existing
action, so no new keybind — rebindable via the Settings panel.

Frames the next core-panels work for a fresh session, after B.1 (drag spine) +
B.2 (toolbar reorder/remove + wire) + toolbar collapse merged this session.
Three sub-phases in order: (A) minimal window manager (open/close + I-key toggle;
UiHost has no open/close API today, windows are always-on); (B) inventory window
(Stream C, synthesis §4 — UiItemList grid + sub-window mount + wire gaps +
InventoryController; the drag SOURCE that closes B.2's drag-from-inventory via a
SourceKind==Inventory branch in ToolbarController.HandleDropRelease); (C) paperdoll
UiViewport (Type 0xD) + Core→App IUiViewportRenderer seam, heaviest, last. Spell
bar deferred. Reuse the shipped spine/ShortcutStore/wire. Paste-able new-session

UiElement.MaxHeight + ResizableEdges mask; UiCollapsibleFrame snaps height to the nearer
of {collapsed,expanded} and toggles row-2 visibility; GameWindow computes the two heights
from the layout + top-anchors the content. Amends IA-17. UiNineSlicePanel unsealed to
allow subclassing.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
User request: the toolbar frame resizes vertically between one row (row 2
hidden, minimum) and two rows (shown), SNAPPING between the two stops; default
expanded. Small toolkit feature: UiElement.MaxHeight + a ResizableEdges mask
(bottom-edge-only) + a UiCollapsibleFrame (snaps height to the nearer stop and
ties row-2 visibility to it in OnTick) + the GameWindow mount (compute the two
heights from the layout, top-anchor the content so row 1 never reflows). Retail's
real mechanism is keystone.dll (no decomp) + the dat stacks both rows always —
so this is a toolkit UX from the user's retail observation; amends IA-17.

The final B.2 review found the TS header undercounted: there are 32 contiguous
rows (TS-1..TS-32) but the header read "31". The base already undercounted (said
"32" with 33 rows TS-1..TS-33); deleting TS-33 with a literal 32→31 decrement
preserved the off-by-one. Set the header to the verified actual count.

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.

Bite-sized TDD plan, three slices: (1) Core ShortcutStore + the AddShortcut
0x019C/RemoveShortcut 0x019D wire (rename BuildAddShortcut to the real
Index/ObjectId/SpellId/Layer fields; SendAddShortcut/SendRemoveShortcut); (2)
spine extensions (OnDragLift hook; ghost snapshotted at BeginDrag at full
opacity; FinishDrag delivers a drop only on a real hit); (3) ToolbarController
as the live handler (store-driven Populate w/ lazy-load; green-cross FA overlay;
OnDragLift removes + HandleDropRelease places + bumps displaced→source; wire
actions injected from GameWindow). Amends AP-47, deletes TS-33. Spec + plan

From the user's visual-gate feedback + a retail decomp trace this session.
Retail's model is remove-on-lift / place-on-drop / no-restore (confirmed:
RecvNotice_ItemListBeginDrag 0x004bd930 → RemoveShortcut 0x004bd450 at lift;
HandleDropRelease 0x004be7c0 places + bumps displaced → source; off-bar drop
leaves it removed). This unifies the user's points 3/4/5 into one mechanism.
Verified the drop sprite against client_portal.dat: 0x060011F9 = green RING
(inventory), 0x060011FA = green CROSS (toolbar) — user was right.
Scope (toolbar-internal; drag-from-inventory is Stream C): spine extensions
(lift hook on IItemListDragHandler; ghost snapshotted at BeginDrag at full
opacity so it survives the source emptying; FinishDrag delivers a drop only on
a real hit, off-bar = nothing); a mutable 18-slot ShortcutStore; ToolbarController
as the live handler (OnDragLift removes; HandleDropRelease places + bumps); the
AddShortcut 0x019C / RemoveShortcut 0x019D wire (fix the BuildAddShortcut param
names; SendAddShortcut/SendRemoveShortcut on WorldSession); green-cross overlay.
Amends AP-47 (ghost now full opacity), retires TS-33 (real wire replaces the stub).

Filed from the B.1 spine code review. No-op today (toolbar Clicked guards

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.

Stream B.1 of the 2026-06-18 handoff — the shared widget-level drag-drop
infra that both shortcut-drag (B) and the inventory window (C) sit on.
Four design decisions confirmed with the user this session:
1. Payload = typed ItemDragPayload record snapshotted at drag-begin
(ObjId/SourceKind/SourceSlot/SourceCell); SourceContainer derived at
drop from ClientObjectTable (single source of truth).
2. Cursor ghost painted by UiRoot via a generic UiElement.GetDragGhost()
hook — keeps UiRoot item-agnostic; floats above all windows.
3. Cell (UiItemSlot) is the drop-target hit unit + accept/reject overlay
owner, delegating the decision + dispatch UP to its parent UiItemList's
registered IItemListDragHandler (faithful to retail cell->ItemList_DragOver
->m_dragHandler; scales to the inventory N-cell grid).
4. PR ships infra + a visible toolbar STUB handler (logs, no wire) so the
ghost/overlay/dispatch are confirmable this session; AddShortcut/Remove
wire is Stream B.2.
Retail-grounded: InqDropIconInfo flags (&0xE==0 fresh / &4 reorder, reject
state 0x10000040) confirmed live at gmToolbarUI 0x004bd162; the cell
begin-drag/CatchDroppedItem/RegisterItemListDragHandler chain at decomp
229344/229744/230461. Planned register rows: AP-47 (ghost reuses full icon
at reduced alpha vs retail m_pDragIcon) + TS-33 (toolbar drop stub pending
B.2). No new wire format in the spine itself.
