fix(combat): apply server attack motions locally

Route accepted non-autonomous local UpdateMotion state through retail's wholesale interpreted-motion funnel, so ACE-selected melee and missile actions use the normal motion queue and action-stamp gate. Share nullable wire conversion with remotes and remove the local direct command replay.

Typed window-visibility events own Highlight/Normal state. Use and Examine act on selection or enter their one-shot retail target modes, with exact Appraise wire dispatch and retail cursors. Warning-free App build and 4,747-pass / 5-skip Release suite are green; the connected live gate passed 2026-07-11. AP-101 is narrowed to the remaining ammo-number display.
 - **Wave 4.4e implemented — exact missile ammo number (live gate pending).** Pure Core reproduces retail's thrown-weapon-vs-separate-ammo resolution over the ordered player equipment list and its zero-to-one count normalization. Relevant equipment/stack events update authored missile indicator `0x10000194` with the DAT font. Warning-free Release build and 4,754-pass / 5-skip suite are green; AP-101 is retired.
 - **M2 held-object parenting shipped and live-gated 2026-07-11.** The combat toggle now ports `GetDefaultCombatMode` over ordered equipped contents, so a bow requests Missile instead of the old hardcoded Melee. CreateObject preserves parent/placement/timestamp fields, `0xF749` ParentEvent is handled, and `EquippedChildRenderController` renders the weapon as a separate child composed from the animated hand part + holding frame + child placement frame. Live gate passed: bow selected missile stance, rendered in-hand, followed animation, unequipped cleanly, and melee remained correct. App Release builds with zero warnings; the full 4,765-pass / 5-skip suite is green. AP-111 is retired; research: `docs/research/2026-07-11-combat-default-and-parent-event-pseudocode.md`.
+- **M2 local attack receive funnel implemented 2026-07-11; live gate pending.** Retail `ExecuteAttack` only sends the request; ACE chooses the concrete melee/missile action and returns it in a non-autonomous mt-0 `UpdateMotion`. The local branch now runs that state through the same constructor-defaulted `MoveToInterpretedState` funnel and 15-bit action-stamp gate as remotes, then applies sticky/long-jump tails. The old local-only direct `Commands[]` replay is deleted. Shared conversion lives in `InboundInterpretedMotionFactory`; research: `docs/research/2026-07-11-local-combat-motion-pseudocode.md`.

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.

+# Local combat UpdateMotion — retail receive pseudocode
+
+Date: 2026-07-11
+
+## Question
+
+Who chooses and plays the local player's melee or missile attack motion?
+
+## Named-retail oracle
+
+- `ClientCombatSystem::ExecuteAttack` at `0x0056BB70` sends the targeted
+  melee/missile request and updates combat-repeat state. It does not choose a
+  concrete swing command and does not play an animation locally.
+- `CPhysics::SetObjectMovement` at `0x00509690` rejects a local autonomous
+  echo, but accepts a newer non-autonomous movement event, stores
+  `last_move_was_autonomous = false`, calls `unpack_movement`, then returns 1
+  so `CommandInterpreter::LoseControlToServer` runs.
+- `MovementManager::unpack_movement` at `0x00524440`, case 0, unpacks an
+  `InterpretedMotionState`, calls `move_to_interpreted_state`, then applies the
+  sticky-object and standing-long-jump trailers.
+- `CMotionInterp::move_to_interpreted_state` at `0x005289C0` copies the state
+  wholesale, reapplies style/forward/side/turn, and dispatches fresh command
+  list entries under the 15-bit `server_action_stamp` gate. The player skips
+  only command entries whose autonomous bit is set.
+
+## ACE cross-reference
+
+ACE's `Player_Melee.DoSwingMotion` selects the actual maneuver from the combat
+table, constructs a `Motion`, marks the target sticky, and broadcasts it.
+Missile attacks similarly enqueue the server-selected aim action, followed by
+reload and Ready. `MovementData.IsAutonomous` documents the wire split as
+client-initiated `true`, server-initiated `false`.
+
+## Retail pseudocode
+
+```text
+on local attack input:
+    send TargetedMeleeAttack or TargetedMissileAttack
+    do not invent or play a swing locally
+
+on UpdateMotion for local player:
+    apply movement and server-control sequence gates
+    if event.isAutonomous:
+        drop the entire event
+
+    player.lastMoveWasAutonomous = false
+    interrupt current move
+    unstick
+    apply outer style if it changed
+
+    if movementType is MoveTo/TurnTo:
+        route to MoveToManager
+        return
+
+    if movementType == InterpretedMotionState:
+        ims = constructor defaults (NonCombat, Ready, speeds 1)
+        unpack every present field over ims
+        move_to_interpreted_state(ims)
+            copy every axis wholesale
+            apply style, forward, sidestep, turn
+            for each fresh command-list entry:
+                if local player and entry.autonomous: skip
+                dispatch entry through the motion table
+        apply sticky target trailer
+        write standingLongJump, including false
+
+    command interpreter loses control to server
+    next local input edge takes autonomous control back
+```
+
+## acdream correction
+
+The local branch already had the autonomous-event rejection and the
+interrupt/style/MoveTo routing, but deliberately skipped the mt-0 wholesale
+copy. It then replayed `Commands[]` directly through
+`AnimationCommandRouter`, bypassing retail's action-stamp and local-autonomous
+gates. The correction routes local mt-0 through the existing
+`MotionInterpreter.MoveToInterpretedState` and persistent motion-table sink,
+exactly like remotes, and removes the direct replay. A shared App-layer factory
+now owns nullable-wire-to-constructor-default conversion for both branches.
