Upgrade and validation notes
- The application database requires pgvector 0.8.0 or newer in the public schema, even when semantic search is disabled. See pgvector setup.
- Known upgrade issue: automatic platform registry synchronization rejects an existing registry version of
1.1.0-alpha.1.1. The API may start while registry synchronization remains incomplete. This alpha does not include a fix. - Unit, registry, and Temporal checks passed on the base commit. Scheduled integration tests did not run because CI SSH authentication failed; publication proceeds with that validation exception accepted.
- The workspace sync MCP tools from #3566 were reverted before this release. The workflow dependency fallback fix was already present in
1.1.0-alpha.1.1.
