+# US03-05 — Automate Phase C End-to-End Acceptance
+
+Epic: [E03](../E03-album-proposals.md)
+
+As a delivery owner, I want automated proposal journeys so generation, editing, and
+approval remain deterministic and non-mutating.
+
+## Acceptance criteria
+
+- Journeys cover evidence aggregation, success, provider failure, invalid name,
+  collision, editing, stale approval, valid approval, reload, and restart.
+- Tests assert provider inputs, persisted versions, and unchanged fixture paths.
+- Story IDs US03-01 through US03-04 map to passing automated tests.
+
+## Automated tests
+
+- One command runs Phase C API and Playwright suites with the deterministic provider.
+- Phase A–B end-to-end suites remain green.
+
+## Dependencies
+
+- US03-01 through US03-04
