@@ -203,7 +203,7 @@ AP-94..AP-110 for the confirmed retail-UI completion gaps.
 | AP-96 | Layout/property import loses raw edge-mode semantics (especially 3/4) and treats default scalar values as absent, so explicit `false`/`0` cannot override inheritance | `src/AcDream.App/UI/Layout/ElementReader.cs`; `LayoutImporter.cs` | Existing shipped layouts are hand-gated; Wave 1 adds presence-aware properties and the exact solver | Non-reference resizing recenters/stretches incorrectly; derived DAT properties silently inherit the wrong base value | `UIElement::UpdateForParentSizeChange @ 0x00462640`; production LayoutDesc inheritance |
 | ~~AP-97~~ | **RETIRED 2026-07-10 (Wave 1 retained-widget foundation)** — the prior generic Device-timer premise was a decomp misread. Named retail polls the hovered element's tooltip deadline, then broadcasts global UI time message `3`; it does not expose the assumed arbitrary timer queue. `UiRoot.Tick` now preserves that order and subtree removal clears input/time ownership before another pulse. | `src/AcDream.App/UI/UiRoot.cs`; `IUiGlobalTimeListener.cs` | — | — | `UIElementManager::UseTime` and hover/focus paths, pinned in `docs/research/2026-07-10-retained-widget-foundations-pseudocode.md` |
 | ~~AP-98~~ | **RETIRED 2026-07-10 (Wave 2.3)** — typed handles/manager own lifecycle; every production/Studio window uses `RetailWindowFrame`; schema-v2 `UiWindowLayout` persists outer bounds, visibility, toolbar collapse, and chat maximize by character/resolution with legacy-radar migration, nearest-resolution fallback, clamping, and a pre-login `default` write guard. Chat maximize uses DAT 100–360 limits and preserves its lower edge when growing upward. | `src/AcDream.App/UI/RetailWindowManager.cs`; `RetailWindowLayoutPersistence.cs`; `RetailWindowHandle.cs`; `Layout/RetailWindowFrame.cs`; `ChatWindowController.cs`; `SettingsStore.cs` | — | — | `gmMainChatUI::HandleMaximizeButton @ 0x004CCE50`; retail `saveui/loadui` behavior |
-| AP-99 | Shared item activation implements only a subset of `ItemHolder::UseObject`/placement legality and confirmation policy | `src/AcDream.App/UI/ItemInteractionController.cs` | Current PvE use/equip/container flows cover the M2 loop; Wave 3 ports the complete pure decision matrix | Vendor/trade/busy/confirmation/target edge cases send the wrong action or permit an illegal use | `ItemHolder::DetermineUseResult @ 0x00588460`; `UseObject @ 0x00588A80`; `AttemptPlaceIn3D @ 0x00588600` |
+| ~~AP-99~~ | **RETIRED 2026-07-11 (Wave 3.2)** — Core `ItemInteractionPolicy` ports the complete ordered `DetermineUseResult`/`UseObject`/`AttemptPlaceIn3D` matrix; PWD flags and `CombatUse` survive CreateObject; component-pack membership comes from portal.dat; App owns throttle, UseDone-balanced busy state, target mode, wire/optimistic dispatch, and typed confirmation/auxiliary seams. The two corrupt decompiler operands were pinned from matching x86 as `BF_REQUIRES_PACKSLOT` and `BF_VENDOR`. | `src/AcDream.Core/Items/ItemInteractionPolicy.cs`; `src/AcDream.App/UI/ItemInteractionController.cs` | — | — | `ItemHolder::DetermineUseResult @ 0x00588460`; `UseObject @ 0x00588A80`; `AttemptPlaceIn3D @ 0x00588600` |
 | AP-100 | Cursor semantics cover only a reachable subset of retail states, and widget cursor media can outrank authoritative global target mode | `src/AcDream.App/UI/CursorFeedbackController.cs`; `src/AcDream.App/Rendering/RetailCursorManager.cs` | Target-use art works for current flows; Wave 3 ports the full table and precedence | Hovering UI can replace the use/examine/busy/combat cursor; unsupported branches fall back to OS art | `ClientUISystem::UpdateCursorState @ 0x00564630` |
 | AP-101 | Toolbar quick-slot actions and most panel/Use/Examine/combat controls are not fully dispatched; selected-object mana and stack entry/slider are absent | `src/AcDream.App/UI/Layout/ToolbarController.cs`; `GameWindow.OnInputAction` | Item click/use, stance indicators, health/name, and some toggles are present | Bound retail keys/buttons do nothing and item/stack selections show incomplete state | `gmToolbarUI @ 0x004BD0C0..0x004BF380`; LayoutDesc `0x21000016` |
 | AP-102 | Inventory-to-occupied toolbar drop treats the inventory source index as though it were a vacated toolbar slot for the displaced shortcut | `src/AcDream.App/UI/Layout/ToolbarController.cs` drop planner | Normal empty-slot and toolbar-reorder paths work; Wave 4 makes the transaction source-aware | The displaced shortcut is lost or moved to an unrelated slot | `gmToolbarUI::HandleDropRelease @ 0x004BE7C0` |
