+## Batch AE Runtime gameplay-owner wiring replacement
+
+Batch AE converts the nine approved consumer-wiring source readers across
+`RuntimeActionOwnershipTests`, `RuntimeCharacterOwnershipTests`,
+`RuntimeInventoryOwnershipTests`, and `RuntimeMovementOwnershipTests`. No
+product source changes and no test is removed. The two approved whole-tree
+construction policies—one action-owner policy and one movement-owner policy—
+remain source-aware by design and are not part of the 85 staged replacements.
+
+The replacements use reflected fields, properties, constructor parameters,
+compiled child access, and shutdown-root metadata to prove that:
+
+- retained UI, session composition, graphical command adapters, and item
+  interaction borrow the canonical action children and the exact Runtime
+  transaction owner, with no App `InteractionState` or UI-side transaction
+  construction;
+- `GameWindow` owns one `GameRuntime`, constructs no character child root,
+  and projects its Spellbook/LocalPlayer properties through
+  `RuntimeCharacterState`; content installation, session routing, retained UI,
+  options, and movement-skill updates all consume that owner;
+- the deleted App character-option and movement-skill owner types remain
+  absent, while Runtime's option replacement and movement-skill update edges
+  remain live;
+- `GameWindow` constructs none of the displaced inventory/item-mana/container/
+  shortcut snapshot owners; retained UI and item interaction use the Runtime
+  action transaction, session bindings use the Runtime shortcut store and use
+  completion, and shutdown carries only `GameRuntime`;
+- `ToolbarController` retains the exact `ShortcutStore` without constructing a
+  mirror, provider delegate, or loaded-state latch, and spell UI has no second
+  local mutation calls for filters, desired components, or favorites; and
+- graphical input, both runtime adapters, and both shutdown roots borrow the
+  exact `RuntimeLocalPlayerMovementState`, including its autorun and typed
+  command execution edges.
+
+`CompiledCallGraph.ReadOwned` was added as a test-only metadata facility. It
+reads declared owner methods plus compiler-generated acquisition/callback
+closures, so a typed dependency carried by a UI factory remains inspectable
+without freezing the lambda's source spelling.
+
+Verification follows the proportionate R3 policy:
+
+- all 11 focused ownership methods pass, including the two retained whole-tree
+  policies adjacent to the nine replacements;
+- the complete `AcDream.App.Tests` hermetic lane passes 5,381/5,381 with zero
+  skips or failures;
+- the complete locked Release build covers all 44 projects with zero warnings
+  and zero errors; and
+- a targeted scan finds source reads only in the two explicitly retained
+  whole-tree policy methods. The final inventory and twelve-assembly Release
+  gate remain deferred to closeout.
