Release 1.8.0

Validation Deep Checks

Four new validation improvements completing the gap analysis:

Schema Kind-Specific Deep Checks

• Flat schemas warn if >1 data node (typically a single table/collection)
• Time-series schemas warn if no indices defined (need time dimension index)
• Hierarchical schemas warn if multiple data nodes but no links (need tree structure)
• Star schemas warn if multiple data nodes but no links (need fact→dimension links)
• Relational FK type mismatch upgraded from Warning to Error

Adaptor Message Direction Compatibility

• Inbound adaptors error if handling Commands/Queries from target (should handle Events/Results)
• Outbound adaptors error if handling Events/Results from target (should handle Commands/Queries)
• Fixed pre-existing bug in adaptor cross-context type resolution

Handler Message Type vs Container Type

• Repository handlers warn if handling events (should handle commands/queries)
• Projector handlers warn if handling commands/queries (should handle events)

Streaming Sink Reachability

• Reverse BFS from each sink checks for upstream path from any source
• Warns if a connected sink has no upstream source

Test Coverage

• 4 new test cases with .check expectation files
• 26 individual validation messages verified
• 268 passes tests, 280 language tests — all passing
