Fast Explore Data Discovery EKS Browser QA

Slot: fast-explore-data-discovery App: https://fast-explore-data-discovery-app.agent-dev.mage.ai/mageai-1-dev/pipelines

Source readback

Critical frontend/backend/plugin files matched local SHA-256 in both app and server pods before browser QA.

Browser simulation

Chat	Completed	Duration	Evidence
02-simple-thread	yes	9.5s	simpleResponse
03-pipeline-list-thread	yes	15.5s	simpleResponse, pipelineNames
04-data-preview-thread	yes	34.0s	simpleResponse, pipelineNames, dataPreviewArtifact, parquetOutput

Final data-preview state

• Data preview artifact auto-opened: yes
• Rendered table rows visible: yes
• Artifact details: 32 exact rows, 8 columns, Parquet block output.

Console

Console warnings/errors were captured in proof.json. The final captured browser state had no console messages recorded by the QA harness.

Targeted validation

• EKS frontend unit slice: 72 passed.
• EKS discovery resource slice: 57 passed.
• EKS backend Sidekick/data-preview slice: 577 passed.
• Residual: plugins/mage-agent-plugin/mage-agent/tests/test_mcp_protocol.py still expects block_code_update and related MCP protocol guidance, but this branch's current COMPOSED_TOOL_CONTRACTS does not expose that tool locally or in the EKS pod. I did not change that protocol surface as part of the data-preview auto-open behavior.
