+## Result
+
+Selection identity, combat mode/known target health, and retail's temporary
+Use/Examine/Use-Item-On-Target mode now form one presentation-independent
+Runtime lifetime group.
+
+`RuntimeActionState` constructs and owns the exact three mutable children.
+`GameWindow` owns one Runtime action root, while Program/plugin selection,
+retained UI, session routing, input/combat consumers, and current-runtime
+commands/views borrow its exact children. No production App path can construct
+another selection, combat, or interaction-mode owner.
+
+The old `AcDream.App.UI.InteractionState` moved to
+`AcDream.Runtime.Gameplay`. `ItemInteractionController` now requires the exact
+injected state and has no private fallback.
+
+## Retail behavior preserved
+
+No selection, combat, or item-use algorithm changed.
+
+- `SelectionState` retains
+  `ACCWeenieObject::SetSelectedObject @ 0x0058C2E0`: commit the changed
+  selection and previous identities before synchronous observers, and
+  deduplicate a same-object selection.
+- `CombatState.Clear` retains
+  `ClientCombatSystem::Begin @ 0x0056A460`: session reset returns to
+  NonCombat and clears known target health.
+- target-mode entry/acquisition/cancellation remains the existing
+  `ItemHolder::UseObject @ 0x00588A80` projection.
+- commands remain synchronous at the existing press-time boundary; this slice
+  adds no queue or frame of latency.
+
+## Ownership and failure behavior
+
+- `RuntimeActionState.View` projects revisions plus selected/previous identity,
+  combat mode, known-health count/query, and interaction mode without copying
+  a mutable collection.
+- reset attempts interaction, selection, and combat suffixes even when one
+  borrowed observer throws.
+- terminal disposal is failure-safe: it clears all children, detaches Runtime's
+  internal revision subscriptions, and becomes terminal even when observers
+  fail.
+- two Runtime action roots in one process remain completely isolated.
+- `RuntimeGameplayOwnership` now includes the action root in its combined
+  convergence ledger.
+- terminal App shutdown releases UI/session borrowers before disposing the
+  Runtime action root and then the canonical entity/object lifetime.
+
+Production source guards scan all non-Studio App sources and prove that only
+the Runtime owner constructs `SelectionState`, `CombatState`, or
+`InteractionState`. Existing Runtime dependency and assembly-load closure
+tests prove no App, UI, Silk.NET, OpenAL, Arch, or ImGui dependency entered the
+kernel.
+
+## Automated gates
+
+All commands ran in Release:
+
+- `dotnet test tests/AcDream.Runtime.Tests/AcDream.Runtime.Tests.csproj`:
+  182 passed.
+- `dotnet test tests/AcDream.App.Tests/AcDream.App.Tests.csproj`:
+  3,779 passed / 3 fixture-generator skips.
+- `dotnet build AcDream.slnx -c Release`: passed.
+- `dotnet test AcDream.slnx -c Release --no-build --no-restore`:
+  8,550 passed / 5 established skips.
+- `git diff --check`: passed.
+
+## Exact-binary connected gate
+
+Report:
+`logs/connected-world-gate-20260726-104445/report.json`.
+
+The report identifies exact source/binary commit
+`b298f99f913249d299796e6a71f7a9b6b283ac1a` and passes:
+
+- six capped login/outdoor/world-edge/dungeon/revisit checkpoints;
+- one fresh uncapped-process reconnect checkpoint;
+- 7/7 complete reveal/readiness checkpoints and zero invariant failures;
+- 245.219-second capped and 61.321-second reconnect sessions;
+- graceful logout and code-zero exit for both processes;
+- zero failures;
+- one expected warning covering 25 empty world-edge landblocks.

+The Windows session was disconnected rather than active RDP during this run,
