+# US02-07 — Automate Phase B End-to-End Acceptance
+
+Epic: [E02](../E02-unified-workflow-shell.md)
+
+As a delivery owner, I want Phase B workflow automation so durable jobs and migrated
+views are proven through real process and browser boundaries.
+
+## Acceptance criteria
+
+- Journeys cover shell loading, workflow blockers, safety review, analysis start,
+  progress, SSE reconnect, polling fallback, cancellation, resume, and error inspection.
+- A second conflicting mutation is rejected while read-only browsing continues.
+- NSFW fixture IDs never reach the fake vision provider and decisions survive restart.
+- Story IDs US02-01 through US02-06 map to passing automated tests.
+
+## Automated tests
+
+- One documented command runs Phase B API, worker-recovery, and Playwright suites.
+- The Phase A suite runs unchanged as a required regression gate.
+
+## Dependencies
+
+- US02-01 through US02-06
