@@ -2060,7 +2060,7 @@ See divergence register **AP-59**.
 **Root cause / status:** The selection-state wire was deferred out of D.5.1 scope; the meter/slider elements are present in LayoutDesc 0x21000016 but hidden (no backing data). D.5.3 is the planned port.
 - **D.5.3a (2026-06-18):** the Health meter (0x100001A1) + the object-name line (0x1000019F) + the overlay state (0x100001A0) are wired via `SelectedObjectController` (port of `gmToolbarUI::HandleSelectionChanged`); `SelectionChanged` event on `GameWindow`; `QueryHealth (0x01BF)` sent on select. Spec/plan: `docs/superpowers/specs|plans/2026-06-18-d53a-*`. **Still deferred:** the Mana meter (0x100001A2 — owned-item-only; no remote-target mana path yet). Divergence row AP-46.
 - **D.5.3a visual gate PASSED (2026-06-20):** name top-aligned in the bar sprite's black band, friendly NPCs/Doors name-only, players/monsters get the bar (gated on PWD BF_ATTACKABLE/BF_PLAYER), bar appears on assess/damage (UpdateHealth-driven, AP-47 retired), brief green selection flash. Fixed during the gate: the two magenta end-lines (UiMeter.DrawHBar resolved slice id 0 → 1x1 magenta placeholder → 1px caps), the stack-entry black box (hid 0x100001A3), and the flash being eaten by a framebuffer-dump diagnostic. Commits `8f627cc` (fixes), `0796585` (CLI apparatus). **Remaining for #141:** Mana meter (0x100001A2).

One Core `StackSplitQuantityState` feeds both controls and the selected-source merge amount. Live visual gate pending.

 - **✓ SHIPPED — Wave 4.3a shortcut-alias boundary.** Drag feedback now preserves retail's neutral/accept/reject distinction. Inventory and paperdoll apply the `(DropItemFlags & 0xE) == 0` physical-item gate, so a toolbar alias can reorder within the toolbar but can never move, unwield, wield, or drop the object it references. Live equipped-helmet gate passed 2026-07-11: inventory drop removed only the shortcut.
 - **✓ SHIPPED — Wave 4.3b source-aware toolbar transactions.** Pure Core `ShortcutDropPlanner` ports `gmToolbarUI::HandleDropRelease @ 0x004BE7C0`: fresh inventory drops displace cyclically right (with wrap), shortcut aliases restore to their vacated source, duplicate objects are removed before placement, full bars intentionally lose the displaced entry when retail finds no empty slot, and every transaction is planned before local mutation then emitted in exact Remove/Add order. Full-stack rekey planning preserves the raw spell word. AP-102 retired; 4,646 automated tests pass; live inventory-to-occupied displacement and toolbar reorder gate passed 2026-07-11.
 - **✓ SHIPPED — Wave 4.3c remaining drop branches + stack merge.** `UiButton` now has a reusable retained item-drop-target seam; gmToolbarUI's inventory/backpack button accepts only fresh physical items, draws the exact authored green-arrow overlay `0x060011F7`, and sends them to the player container while shortcut aliases remain neutral. Pure Core `StackMergePlanner` ports `IsMergeAttemptLegal @ 0x00586F30` and `AttemptMerge @ 0x005878F0`; inventory drops try legal same-WCID stack merges before normal insertion, clamp `0x0054` amount to destination capacity, immediately broadcast retail's misleadingly named `FullMergingItem` notice to rekey the toolbar, and select the destination. Existing destination shortcuts are removed before rekey. Warning-free Release build and 4,660 tests pass; live stack-merge gate passed 2026-07-11. Backpack-button drop gate remains pending.
-- **✓ IMPLEMENTED — Wave 4.4a selected-stack controls.** `SelectedObjectController` now formats retail's count-first stack name, reveals the authored numeric entry and horizontal DAT slider, initializes both to the full stack, refreshes them on selected-object stack changes, and shares one Core split quantity with inventory merge. Exact cdb-pinned 1000-step slider rounding, entry clamping, real-DAT fixture media, and pointer drag have conformance tests. Warning-free App Release build and 4,683 tests pass; live visual gate pending 2026-07-11. Selected-item mana and remaining toolbar buttons stay under AP-101.
+- **✓ IMPLEMENTED — Wave 4.4a selected-stack controls.** `SelectedObjectController` formats retail's count-first `NAME_APPROPRIATE` stack name from the wire plural, reveals the authored right-aligned numeric entry and horizontal DAT slider, initializes both to the full stack, refreshes them on selected-object stack changes, and shares one Core split quantity with inventory merge. The thumb owns its raw pointer position so quantity 1 and maximum reach the exact endpoints; entry writes retain retail's `split/max` attribute behavior.

Warning-free App Release build and 4,691 tests pass; live visual gate pending 2026-07-11. Selected-item mana and remaining toolbar buttons stay under AP-101.
 - **✓ SHIPPED — Character window** (`LayoutDesc 0x2100002E`, `CharacterStatController`, 2026-06-26, same branch). **Visually user-confirmed 2026-06-26 — Attributes tab reads as retail.** Three tabs, header (name/heritage/PK), large-gold level number (dat font, `largeDatFont` 18px), "Total Experience (XP):" + "XP for next level:" captions, 9-row attribute list (icons + right-aligned values + Health/Stamina/Mana vitals), click-to-select (top/bottom selection bars + footer State-B "{Attr}: {value}" / "Experience To Raise: Infinity!" + affordability-gated raise triangles), centered footer. User noted "still needs some polish for later" — deferred to Issue #158.
 - **✓ 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.
 - **Roadmap correction (2026-07-10):** the completion order is now the architecture-first campaign in `docs/superpowers/plans/2026-07-10-retail-ui-fidelity-completion.md`. Retail `gmToolbarUI` is object-only: preserve `ShortCutData.index_`, `objectID_`, and `spellID_`, but do not invent spell glyphs on this bar. `PlayerModule::favorite_spells_[8]` feeds separate spell bars.
