 Status: completed
 
 DoD:
-- wizard step 2 uses auth selector instead of `${secrets.*}` placeholders
-- upstream auth is serialized into `execution_config.auth_profile_ref`
-- raw auth headers are removed from primary wizard UX
-- quick-create secret and auth profile flow works against live backend endpoints
-- node checks, UI docker build, and workspace check pass
+- Playwright regression suite passes for the Alpine UI shell
+- manual smoke checklist exists for auth, workspace, operations, agents, API keys, logs, usage, secrets, wizard, streaming
+- public smoke targets are linked from the regression checklist
+- docs and TASKS reflect the current post-streaming baseline
 
 ## Next
 
-- `feat/manual-regression-pass`
+- `feat/post-regression-fixes`
