+# Reproduce Button with Deterministic Replay Progress
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Reusable button component that triggers deterministic replay verification of verdicts/scores. Shows inline progress during replay execution and displays results including pass/fail status and drift detection.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/shared/components/reproduce/`
+- **Components**:
+  - `replay-progress` (`src/Web/StellaOps.Web/src/app/shared/components/reproduce/replay-progress.component.ts`)
+  - `replay-result` (`src/Web/StellaOps.Web/src/app/shared/components/reproduce/replay-result.component.ts`)
+  - `reproduce-button` (`src/Web/StellaOps.Web/src/app/shared/components/reproduce/reproduce-button.component.ts`)
+- **Services**:
+  - `replay` (`src/Web/StellaOps.Web/src/app/shared/components/reproduce/replay.service.ts`)
+- **Models**:
+  - `src/Web/StellaOps.Web/src/app/shared/components/reproduce/replay.models.ts`
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to the relevant page/section where this feature appears
+  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
+- **Core verification**:
+  - [ ] Verify the component renders correctly with sample data
+  - [ ] Verify interactive elements respond to user input
+  - [ ] Verify data is fetched and displayed from the correct API endpoints
+- **Edge cases**:
+  - [ ] Verify graceful handling when backend API is unavailable (error state)
+  - [ ] Verify responsive layout at different viewport sizes
+  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
