+# Evidence: Fix Delete Prototype Interaction (#767)
+
+## Task Summary
+- **Target Issue:** upstream [#767](https://github.com/storytold/figcraft/issues/767) - "When deleting a prototype, it also deletes the component."
+- **PR:** [#776](https://github.com/storytold/figcraft/pull/776)
+- **Branch:** `fix/delete-prototype-interaction`
+- **Head Commit:** `bc5a2b8`
+
+## Root Cause
+When an interaction noodle or interaction editor was clicked/selected in the Prototype tab, `proto_canvas.rs` set document selection to `[n.source]` (the layer). When Delete or Backspace was pressed, `shortcuts.rs` dispatched `edit.delete` without checking if an interaction was active, deleting the component instead of the interaction connection.
+
+## Implemented Fix
+- Added `has_selected_interaction`, `delete_selected_interaction`, and `close_editor` in `crates/ui-egui/src/proto_panel.rs`.
+- Handled `Key::Delete` and `Key::Backspace` in `shortcuts::key_event` and `run_binding` when in `RightTab::Prototype` with an active interaction, removing the interaction with `proto.interaction.remove` rather than deleting the layer.
+- Added canvas deselect on click in `crates/ui-egui/src/proto_canvas.rs` and tab-switch close in `crates/ui-egui/src/right.rs`.
+- Handled `Key::Escape` to close the interaction editor first before stepping out / deselecting layers.
+- Added comprehensive headless regression tests in `crates/ui-egui/src/proto_editor_tests.rs`.
