 | AD-26 | Auto-walk arrival requires facing alignment (invented 5° arrive / 30° walk-while-turning bands); retail's check is `dist <= radius` exact | `src/AcDream.App/Input/PlayerMovementController.cs:575` | ACE does the final `Rotate(target)` server-side before the Use callback; without a local gate the body used items while facing away (user feedback 2026-05-15). Thresholds are NOT retail constants | Arrival delayed by the rotation phase; if heading convergence fights another yaw writer, `AutoWalkArrived` never fires and the queued Use/PickUp never completes | `MoveToManager::HandleMoveToPosition`; `apply_interpreted_movement` |
 | AD-27 | Use/PickUp action re-sent on natural auto-walk arrival; retail sends the action once (server MoveToChain callback completes it) | `src/AcDream.App/Input/PlayerMovementController.cs:322` | ACE's server-side chain may have timed out by the time our body arrives; the close-range re-send hits ACE's WithinUseRadius fast-path | If the server's chain has NOT timed out, the action executes twice — door toggles open-then-closed, use-once interactions double-fire; protocol noise on non-ACE servers | ACE CreateMoveToChain / WithinUseRadius |
 | AD-28 | Chat transcript (`UiText`) and input (`UiChatInput`) are two separate widget classes placed inside their dat-authored container panels; retail's `ChatInterface` uses a single mode-flagged `UIElement_Text` (Type-12) that switches between read and edit mode | `src/AcDream.App/UI/Layout/ChatWindowController.cs:135` (transcript) + `:150` (input) | `UIElement_Text` is inside keystone.dll with no PDB/decomp; a two-widget split is functionally equivalent (read-only scroll, editable input) and is the structural adaptation required by our UiElement architecture | A future consumer expecting a single widget for both read/write (e.g. a plugin calling the chat API and getting one widget back) must be written to the two-widget contract | `UIElement_Text` (Type-12) @ keystone.dll; `gmMainChatUI::PostInit` @0x4ce130 |
+| AD-29 | `ClientObjectTable` fires global `ObjectAdded`/`ObjectUpdated`/`ObjectRemoved` events; consumers filter by guid on their end. Retail dispatches per-object via `NoticeRegistrar` observer dispatch — each UI cell observes only its specific object guid | `src/AcDream.Core/Items/ClientObjectTable.cs:48` (events); `src/AcDream.App/UI/Layout/ToolbarController.cs:115` (guid filter) | `NoticeRegistrar` is inside keystone.dll with no PDB/decomp; global broadcast + consumer-side filter is functionally equivalent for the current panel count and object volumes seen in practice | At high object counts (>1 000 objects), every `ObjectUpdated` wakes every subscribed consumer — O(n·m) notification cost instead of retail's O(1) per-observer dispatch; a consumer that forgets the guid filter processes all objects (a latent correctness bug) | `NoticeRegistrar` (keystone.dll, no PDB); retail per-object observer registration in `CObjectMaint` |

 | TS-29 | Background music (MIDI) + ambient loops not ported: PlayMusic/StopMusic no-op; StartAmbient reserves a handle that never plays | `src/AcDream.App/Audio/OpenAlAudioEngine.cs:331` | Explicitly outside R5 audio-phase scope; a landblock-attached ambient system is planned separately | Silent world where retail has music/atmosphere; code trusting StartAmbient's handle to mean "playing" is already subtly wrong (StopAmbient looks up a never-created source) | retail MIDI + ambient system (r05) |
 | TS-30 | Numbered chat tabs (element ids `0x10000522`–`0x10000525`) render as clickable buttons but do not switch channel filter or affect the transcript — tab state is a no-op | `src/AcDream.App/UI/Layout/ChatWindowController.cs:210` | Retail's tab switching routes transcript lines by chat channel (`gmMainChatUI::gmScrollWindow` sub-windows per tab); the tab wiring is D.5 scope | Tab clicks produce no visible transcript change; retail would filter to the selected channel — all chat always shows in all tabs | `gmMainChatUI::PostInit` tab setup @0x4ce2a0; holtburger chat tab handling |
 | TS-31 | Squelch toggle absent (no `/squelch` slash command, no clickable name-tags to silence); retail's squelch list filters incoming chat lines | `src/AcDream.Core/Chat/ChatLog.cs` | Squelch is a social / moderation feature deferred to post-M1.5; the data structure (`ChatLog`) has no squelch set today | Any player can spam all clients; clickable-name-tag contextual menu (used in retail to squelch, tell, add-to-friends) is absent | `ChatFilter::IsSquelched`; retail right-click player name → Squelch menu |
+| TS-32 | `ClientObjectTable` has no pre-queue for a child `CreateObject` that arrives before its parent (out-of-order PARENTED create); such objects are ingested as root objects and their `ContainerId` links a not-yet-known container. Retail's `null_object_table` + `null_weenie_object_table` hold unresolvable objects until the parent arrives | `src/AcDream.Core/Items/ClientObjectTable.cs` (`Ingest`) | PD↔`CreateObject` ordering is handled (upsert semantics); out-of-order PARENTED creates are observed only at high packet loss or in vendor/corpse multi-object bursts on non-loopback links; deferred to D.5.5+ | A container's child object arriving before the container is ingested as a root item — it won't appear in `GetContents` until the next `RecordMembership` or a move event corrects the parent link | `CObjectMaint::null_object_table` / `null_weenie_object_table` (acclient.h / named-retail pc) |
