[major] Container Placement: new PlacementInitialized event; refined ContainerChanged/PositionChanged gating. [major] Container Placement: accurate payloads (previous/current container & position); swap-aware add/move. [major] Linked Container: primary and linked mirroring (equipment single-slot semantics). [major] Linked Container: redirect when placed in linked first; move owner to primary, then mirror.

[new] Spatial layout: PerCell and BitSetRows fit algorithms; custom hook via TestWithCustomAlgorithm (C++).

[change] Container Placement: single graceful retry path (TryPlaceWithRetry) for transient failures. [change] Container Placement: ResolveById for authoritative container instance resolution. [change] Linked Container: listens to item + container events; clears mirror on container removal/unequip. [change] Consume ability: expanded logs/comments to clarify cancellation causes. [change] Attribute Set: replaced ensure with check/warning for Equipment Managers. [change] Test utilities consolidated into shared event listeners and helpers. [fix] Crash when removing items without stacks fragments. [fix] Consume from gameplay events condition corrected. [fix] Equipment State ability now ends correctly when no animation is found. [fix] Linked Container: prevented duplicate subscriptions and stale mirror memory on deactivate. [fix] Nested Container: prevented duplicate creation on re-activation or load.
