+# Workflow Visualization Replay UI
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Shipped the canonical `Releases > Runs` graph and replay workspace with stable summary, graph, timeline, critical-path, replay, and evidence tabs. Operators can drill into failed steps, deep-link a step drawer with `step=<id>`, move into `Evidence > Verify & Replay`, and return to the same run context without depending on the dead `workflow-visualization` branch.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/workflow-visualization/`
+- **Primary components**:
+  - `run-graph-replay-page` (`src/Web/StellaOps.Web/src/app/features/workflow-visualization/run-graph-replay-page.component.ts`)
+  - `workflow-visualizer` (`src/Web/StellaOps.Web/src/app/features/workflow-visualization/components/workflow-visualizer/workflow-visualizer.component.ts`)
+  - `time-travel-controls` (`src/Web/StellaOps.Web/src/app/features/workflow-visualization/components/time-travel-controls/time-travel-controls.component.ts`)
+  - `step-detail-panel` (`src/Web/StellaOps.Web/src/app/features/workflow-visualization/components/step-detail-panel/step-detail-panel.component.ts`)
+- **Canonical routes**:
+  - `/releases/runs/:runId/summary`
+  - `/releases/runs/:runId/graph`
+  - `/releases/runs/:runId/timeline`
+  - `/releases/runs/:runId/critical-path`
+  - `/releases/runs/:runId/replay`
+  - `/releases/runs/:runId/evidence`
+- **Legacy aliases**:
+  - `/workflow-visualization/:runId`
+  - `/workflow-visualization/:runId/:tab`
+- **Query state**:
+  - `step=<stepId>`
+  - `returnTo=<encoded route>`
+- **Secondary entry points**:
+  - `Releases > Activity`
+  - release detail replay actions
+  - `Evidence > Verify & Replay`
+  - workflow editor `Preview DAG` mode
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that can access `Releases`, `Evidence`, and workflow administration.
+  - [ ] Navigate to `/releases/runs/<runId>/graph`.
+  - [ ] Ensure run detail, timeline, replay, and workflow graph fixtures or seeded data exist.
+- **Core verification**:
+  - [ ] Verify `Summary`, `Graph`, `Timeline`, `Critical Path`, `Replay`, and `Evidence` tabs render in one mounted run shell.
+  - [ ] Verify graph and timeline step selection open the step drawer and preserve `step=<id>` in the URL.
+  - [ ] Verify replay and evidence actions preserve run context and hand off correctly to `Evidence > Verify & Replay`.
+- **Legacy verification**:
+  - [ ] Verify `workflow-visualization/*` aliases redirect into `/releases/runs/:runId/*`.
+  - [ ] Verify authoring preview renders the graph-only workflow editor mode without runtime replay loading.
+  - [ ] Verify redirect and deep-link behavior tolerate additional context query params.
+
