Description

Session Goal

Assess the paper-corpus summary workflow after a successful idempotency/safety check, then narrow the remaining backend and validation issues blocking reliable summary runs.

Key Activities

• Verified that the summary layer behaves idempotently: the first run writes three items, and the second run skips them without making provider calls.
• Reviewed milestone status for summary artifact generation and confirmed the main backend gap is persistence of run_record.[[json]].
• Distinguished a likely non-blocking Next.js hydration warning from the product-critical issues.
• Proposed a focused validation path for API and frontend behavior, including using a clean terminal for API checks instead of the Next dev-server/browser-console stream.
• Diagnosed duplicate corpus artifacts and recommended canonical chunk_set selection so each source maps to one logical paper.
• Outlined acceptance criteria and commands for validating API health, CSV export, summary input generation, and run observability.
• Recorded a product/workflow direction for the paper workbench: selected-paper summary actions belong in the main workspace, while diagnostics stay separated.
• Noted a FastAPI import crash caused by a missing generate_summary_for_paper export and recommended restoring a compatibility wrapper rather than changing the endpoint.

Achievements

• Confirmed safety/idempotency behavior is working as intended.
• Isolated the highest-priority backend issue to missing run_record.[[json]] persistence.
• Clarified that corpus duplication and artifact hygiene need canonicalization to prevent ambiguous summary inputs.
• Identified a compatibility fix path for the FastAPI import regression.

Pending Tasks

• Implement run_record.[[json]] persistence for summary runs.
• Rebuild or canonicalize corpus artifacts to eliminate duplicate chunk sets.
• Run API validation from a clean terminal and confirm backend startup/import stability.
• Verify frontend summary actions and browser status display after backend fixes.
• Apply the compatibility wrapper for generate_summary_for_paper if still missing.
