docs(D.2b-B): divergence rows + issues/roadmap for inventory population

AP-48: client-side SumCarriedBurden fallback (EncumbranceVal not yet wired).
AP-49: aug capacity (PropertyInt 0xE6) not tracked → un-augmented Str×150.
AP-50: meter direction from geometry (m_eDirection/0x6f not read from LayoutDesc).
AP-51: main-pack cell placeholder icon (equip-pack DID deferred to Sub-phase C).

AP count: 43 → 47 rows. ISSUES: D.2b-B closed entry + remaining B-Wire/B-Drag/C
gaps noted. Roadmap: D.5 sub-phase ledger updated to reflect B-Controller shipped.

+## D.2b-B — Inventory controller (B-Controller): grid population + burden meter + captions SHIPPED
+
+**Closed:** 2026-06-21
+**Component:** ui — D.2b inventory window (gmInventoryUI 0x21000023)
+
+`InventoryController.Bind` wired into the existing inventory-init block in `GameWindow.cs` (commit `03fbf44`). The controller populates the "Contents of Backpack" grid (6 cols × 32 px) and the pack-selector strip from `ClientObjectTable`, drives the vertical burden meter via `BurdenMath.EncumbranceCapacity/LoadRatio/LoadToFill`, and attaches "Burden" + "Contents of Backpack" + `%` captions. Four divergence rows added: AP-48 (client-side burden sum), AP-49 (aug capacity unwired), AP-50 (meter direction from geometry), AP-51 (main-pack icon placeholder). Divergence register + docs commit: `docs(D.2b-B)`. **Remaining open sub-phases:** B-Wire (parse `EncumbranceVal`/PropertyInt 5 from the wire to retire AP-48), B-Drag (drag-from-inventory SourceKind branch closes B.2), Sub-phase C (paperdoll equip-slot `UiItemSlot` registration).

First data-driven *game* panel: `gmToolbarUI` (`LayoutDesc 0x21000016`) — 18 shortcut slots from the persisted `PlayerDescription` SHORTCUT block, real **composited** item icons (opaque type-default underlay via the `EnumIDMap 0x10000004` resolve), **occupancy-gated slot numbers 1–9** (occupied = dark-box peace/war `0x10000042/43`; empty = background `0x1000005e` from cell composite `0x10000341`), **click-to-use** (`ItemHolder::UseObject` → `0x0036`), **peace/war stance** indicator live-wired to `CombatState`, **movable**, and a **chrome frame** (UiNineSlicePanel drawn over content via the new `UiElement.OnDrawAfterChildren` hook).

 - **✓ SHIPPED — D.5.2 — Stateful item-icon system.** Shipped 2026-06-17/18 (`419c3ac`..`fb288ad`, branch claude/hopeful-maxwell-214a12; **visually verified on a live Coldeve server**). Faithful retail icon composite (`IconData::RenderIcons` @0x0058d180): (1) `UiEffects` bitfield captured from the `CreateObject` weenie header (was discarded) → `ItemInstance.Effects`; (2) `IconComposer.GetIcon` rewritten as a 2-stage composite — Stage 1 = drag icon (base + custom overlay) + the effect treatment, Stage 2 = type-default underlay + custom underlay + drag. The effect treatment ports the **surface overload** of `SurfaceWindow::ReplaceColor` (`0x004415b0`): the textured effect tile (`EnumIDMap 0x10000005` by `LowestSetBit(effects)+1`, fallback `0x21` solid-black) is copied **per-pixel** into the icon's pure-white pixels — magical items take the tile's GRADIENT hue, mundane items go black; (3) `PublicUpdatePropertyInt (0x02CE)` parser + `WorldSession.ObjectIntPropertyUpdated` event + `GameWindow` subscription → `ItemRepository.UpdateIntProperty` → icon re-composites live. **Appraise (`0x00C9`) carries NO icon data** (ACE proof: `Icon`/`IconOverlay`/`IconUnderlay`/`UiEffects` all lack `[AssessmentProperty]`) — dropped as a no-op. **Two visual-verification fixes landed after the subagent build:** the `effects==0` recolor MUST run (mundane white edges → black, `40c97a5`) and the tint is a per-pixel GRADIENT not a flat color (the surface overload, `fb288ad`) — both confirmed via clean Ghidra + named decomp.

 - **✓ SHIPPED — D.5.4 — Client object/item data model (foundation).** Shipped 2026-06-18 (`b506f53`..`a33e897`, 11 commits). Renamed `ItemRepository`→`ClientObjectTable` / `ItemInstance`→`ClientObject`; broadened the table to hold EVERY server object (retail `weenie_object_table` shape). `CreateObject` is now the canonical merge-upsert (`ClientObjectTable.Ingest`, retail `SetWeenieDesc` semantics) via a new Core.Net `ObjectTableWiring` (off GameWindow); `DeleteObject` evicts; `PlayerDescription` is a membership manifest (`RecordMembership`); live container-membership index (`GetContents`, retail `object_inventory_table`). `_liveEntityInfoByGuid` retired (selection/describe resolve from the one table). Root fix: the old enrich-existing-only `EnrichItem` dropped `CreateObject`s for items with no `PlayerDescription` stub — live-Coldeve 4/6 hotbar slots blank; items are now created, not dropped. **Crux resolved:** retail is TWO tables (`object_table` + `weenie_object_table`), NOT one — acdream's `WorldEntity` (3D system) + `ClientObjectTable` (data/UI) split was already architecturally faithful; the fix was the ingestion path, not a table unification. 2671 tests green.
 - **☐ D.5.3 — Toolbar selected-object display (issue #140) + spell shortcuts.** Wire the B.4 `WorldPicker`/selection state → the two hidden meters (`0x100001A1` health / `0x100001A2` mana) + the stack slider (`0x100001A4`) + the object-name line, so the bar shows the player's currently-selected world object. Plus **spell shortcuts** — pinned *spells* (vs items) don't render their glyphs yet (`ToolbarController.Populate` skips `ObjectGuid==0`). Together these finish "the bar." (Click-to-use + the peace/war stance indicator landed in D.5.1.)
 - **☐ D.5.5+ — Core panels.** Inventory (`gmInventoryUI`/`gmBackpackUI`), equipment/paperdoll (`gmPaperDollUI`/`gm3DItemsUI` + the `UiViewport` 3D doll), vendor, trade, spellbook. Research drop done (`docs/research/2026-06-16-*`). Depends on **D.5.4** (data model) + the item-slot/list/icon spine (D.5.1/D.5.2) + the **window manager** (Plan 2: open/close/z-order/persist + faithful grip/dragbar drag-resize) + the drag-drop spine wired (`UiRoot` has the chain; the per-cell accept/drop hooks are still stubs in `UiField`). Also deferred from D.5.1: drag/reorder + the `AddShortcut`/`RemoveShortcut` mutate wire.
