Business Problem

Knowledge workflows need transparent local processing and a way to prove what was stored.

Workflow Purpose

Demonstrate deterministic local document processing, PostgreSQL document records, and processing-run tracking.

Persistence Model

  • knowledge_documents
  • knowledge_processing_runs

Verified Counts

  • 3 knowledge document records
  • 1 processing run

Node Sequence

Create sample documentsShape metadataPersist knowledge documentsRecord processing runReturn evidence

Validation Logic

The verified path uses deterministic local processing so the result can be inspected without external API dependency.

Reliability Patterns

  • Processing-run table
  • Document table
  • Static sample data
  • Release workflow export

Security Model

  • No paid external API dependency
  • No private documents
  • Sanitized workflow export

Lessons Learned

  • Local-first AI examples should separate verified behavior from optional model experiments.
  • Persistence proof matters more than visual polish alone.

Optional local model experimentation is outside the verified persistence path.
