 ## [Unreleased]
+- **TUI ActorSelectionOverlay render method rename** (#11042): Renamed `ActorSelectionOverlay._render()` to `_refresh_display()` to avoid shadowing the Textual Widget's internal `_render` method. The overlay class inherits from `textual.widgets.Static`, which has its own `_render` implementation used for rendering widget content. Shadowing this caused incorrect repaint behavior and interfered with Textual's layout pass.
 
 - **Structural Component Output Validation** (#8164): Replaces exact character matching with structural component checking for output validation. Implements three validators covering plan tree output, decision CLI dicts, and structured session snapshots. The `validate_plan_tree` function validates node dicts for required keys (`decision_id`, `type`, `sequence`, `question`, `children`), ULID format, correct types, and sibling ordering. The `validate_decision_dict` function validates decision CLI output against the `Decision.as_cli_dict()` schema with field presence, type, ULID pattern, confidence range [0..1], and boolean field checks. The `validate_structured_output` function validates the StructuredOutput envelope for `command`, `session_id` (ULID), status membership, `exit_code`, and elements integrity. A unified dispatcher (`validate_structured_component_output`) enables routing by target_type. BDD test coverage added in `features/structural_validation.feature`.
