Audit Trails for AI Document Workflows: What To Store

An AI document workflow needs more than logs. Store source records, schema versions, extracted values, approvals, generated outputs, and delivery events.

The Document Intake Contract Nobody Designs Until It Breaks

Reliable document workflows start before extraction. Define intake metadata, rejection reasons, grouping, source trust, and routing before files hit processing.

Large Document Packets Need Workflow Boundaries, Not Bigger Prompts

Large packets fail when teams process them as one document. Design request boundaries, schemas, review states, and outputs around the workflow object.

Document Provenance for API-First Workflows

You can build useful provenance with citations, schema versions, approved values, and generated artifact lineage before adding a full review UI.

Treat the LLM as a Document Worker, Not the Workflow Owner

LLMs are useful inside document workflows, but they should not own intake, state, validation, generated outputs, or customer-facing decisions.

Long Documents Fail Differently Than Large Batches

A 300-page file and 300 one-page files are different engineering problems. Design context, retries, review, and cost controls accordingly.

Forms, Tables, and Free Text Need Different Extraction Strategies

Mixed documents break when every page is treated the same. Use fields for forms, arrays for tables, and Markdown for narrative context.
