Description

Session Goal

Review the paper-corpus / paper-kb workbench state, diagnose reliability issues in summary generation and identity handling, and consolidate a migration plan toward stable canonical paper identifiers and cleaner frontend summary flow.

Key Activities

  • Triaged frontend/backend reliability issues in the paper corpus app: summary 404s were being treated as errors, row-level polling was noisy, and title-derived IDs were identified as brittle.
  • Defined a staged remediation path covering UI semantics, request fanout reduction, React state stability, and a backend identity contract based on short stable paper_uid values.
  • Planned a canonical ID migration with dual-field metadata, alias resolution, canonical summary artifacts, and backward-compatible routing.
  • Clarified that chunk IDs should not be migrated yet; the focus remains on paper identity and summary-state behavior.
  • Diagnosed backend summary generation behavior: GET /summary returning 404 is expected when missing, while POST /summary:generate returning 500 is the real blocker to fix and verify with regression tests.
  • Reviewed corpus artifact routing and chunk-set availability, including the likely cause of zero chunk-set counts when the active corpus path does not see *.chunk_set.[[json]] files.
  • Outlined a repair workflow for active chunk-set generation and corpus path alignment.
  • Evaluated Agent Framework integration for controlled paper summarization, including provider compatibility fixes, JSON enforcement via prompts, smoke tests, idempotent persistence, and a staged rollout from mock to real summaries.
  • Recorded the sprint outcome: repo boundaries and corpus layout are clearer, GROBID-to-chunk_set processing is stabilized, real Agent Framework summary generation is working, and the next bottleneck is summary quality.

Achievements

  • Established a coherent migration strategy from title-derived paper IDs to canonical short paper_uid identifiers.
  • Separated expected missing-summary 404 behavior from actual backend failures.
  • Identified the main remaining backend blocker as the 500 error on summary generation.
  • Confirmed progress toward real LLM-backed summary generation with artifact writing and provider call tracking.
  • Reframed the next sprint around improving summary usefulness and quality rather than infrastructure plumbing.

Pending Tasks

  • Fix the POST /[[api]]/papers/{paper_id}/summary:generate 500 error and add regression coverage.
  • Implement the canonical paper_uid migration and alias-compatible backend routing.
  • Simplify frontend summary fetching so only the selected paper fetches summary state.
  • Verify corpus paths and regenerate missing chunk-set artifacts where needed.
  • Improve summary quality for thesis-literature use cases and validate idempotent persistence in the summary pipeline.
