+# Execution Operations UI
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Shipped the execution-operations cutover so `Ops > Operations` now owns usable JobEngine, Scheduler, and Dead-Letter flows, while the companion `Scanner Ops` pages no longer stop at placeholder console actions. The work repaired stale jobengine or scheduler aliases, completed the missing operator workflows, and kept execution drill-ins on mounted canonical routes.
+
+## Implementation Details
+- **Feature directories**:
+  - `src/Web/StellaOps.Web/src/app/features/jobengine/`
+  - `src/Web.StellaOps.Web/src/app/features/scheduler-ops/`
+  - `src/Web.StellaOps.Web/src/app/features/deadletter/`
+  - `src/Web.StellaOps.Web/src/app/features/scanner-ops/`
+  - `src/Web.StellaOps.Web/src/app/features/platform/ops/`
+  - `src/Web.StellaOps.Web/src/app/core/api/jobengine-jobs.client.ts`
+- **Primary routes**:
+  - `/ops/operations/jobs-queues`
+  - `/ops/operations/jobengine`
+  - `/ops/operations/jobengine/jobs`
+  - `/ops/operations/jobengine/jobs/:jobId`
+  - `/ops/operations/jobengine/jobs/:jobId/dag`
+  - `/ops/operations/jobengine/quotas`
+  - `/ops/operations/dead-letter`
+  - `/ops/operations/dead-letter/queue`
+  - `/ops/operations/dead-letter/entry/:entryId`
+  - `/ops/operations/scheduler/runs`
+  - `/ops/operations/scheduler/runs/:runId/stream`
+  - `/ops/operations/scheduler/schedules`
+  - `/ops/operations/scheduler/workers`
+  - `/ops/scanner-ops`
+  - `/ops/scanner-ops/offline-kits`
+  - `/ops/scanner-ops/baselines`
+  - `/ops/scanner-ops/analyzers`
+  - `/ops/scanner-ops/performance`
+- **Legacy aliases**:
+  - `/ops/jobengine/*`
+  - `/ops/scheduler/*`
+  - `/ops/scanner`
+  - `/ops/scanner/:page`
+  - `/platform-ops/*`
+  - `/platform/ops/*`
+- **Notable repaired behaviors**:
+  - JobEngine job detail and DAG drill-in stay on canonical routes
+  - JobEngine quota actions export usable snapshots instead of placeholder buttons
+  - dead-letter batch replay and resolve call the real client methods and hand back to canonical job detail
+  - scheduler runs can open a route-backed live-stream view
+  - scanner offline-kit, baseline, analyzer, and performance tools perform honest local workflows instead of `console.log`
+
+## E2E Test Plan
+- **Setup**:
+  - [x] Use the local Angular test server from Playwright `webServer` via `npm run serve:test`.
+  - [x] Use a test session with Ops and orchestration scopes.
+- **Core verification**:
+  - [x] Verify canonical JobEngine list and detail navigation.
+  - [x] Verify dead-letter queue replay remains usable on the canonical queue page.
+  - [x] Verify scheduler runs can open the new run-stream page.
+  - [x] Verify scanner-support actions surface honest completion notices.
+- **Cutover verification**:
+  - [x] Verify Angular tests cover alias inventory and the repaired execution workflows.
+  - [x] Verify the production build still completes after the execution cutover.
+
+## Verification
+- Run:
+  - `npm run test -- --watch=false --include src/tests/platform-ops/platform-ops-routes.spec.ts --include src/tests/scheduler_ops/scheduler-orchestrator-ops-ui.behavior.spec.ts --include src/tests/deadletter/deadletter-queue.component.spec.ts --include src/tests/deadletter/deadletter-entry-detail.component.spec.ts --include src/tests/scanner_ops/scanner-ops-settings-ui.behavior.spec.ts --include src/tests/scanner_ops/scanner-ops-supporting-flows.behavior.spec.ts --include src/tests/jobengine/jobengine-execution-ops.behavior.spec.ts`
+  - `npx playwright test tests/e2e/execution-operations-cutover.spec.ts --workers=1`
+  - `npm run build`
+- Tier 0 (source): pass
+- Tier 1 (build/tests): pass
+- Tier 2 (behavior): pass
+- Notes:
+  - Angular targeted tests passed: `7` files, `38` tests.
+  - Playwright passed: `1` scenario.
+  - Production build passed; existing initial bundle and setup-wizard style budget warnings remain unchanged from the baseline.
