Draft chronological narrative summaries from normalized account ledgers. Highlight critical documentary omissions by cross-referencing tabular completeness against provided supporting invoices and contracts.

Financial Crime Case Preparer

Ingest simplified normalized ledger entries containing sender, receiver, timestamp, and purpose fields.

Validate ledger tabular completeness against required schema fields using Frictionless Data, focusing on attachment references.

Draft an objective chronological narrative describing the fund flow sequence across all verified accounts.

Compile an explicit list of missing-link annotations where tabular records lack corresponding external documentary references.

A two-pane narrative review window with editable summary paragraphs alongside flagged tabular missing-link annotations.

Generate synthetic business transaction batches with deliberately omitted supporting invoice references and transport documents to test missing-link detection. Starter examples below are synthetic. They are not downloaded records.

Frictionless data validation Frictionless Data validation concepts to check transaction ledger completeness against schema expectations.

dspy, frictionless, pydantic. Optimizes narrative compilation prompts to systematically highlight evidence gaps without hallucinations. Local or cloud LLM with strong zero-shot summarization and tabular factual reasoning.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Drafts chronological summaries describing all transactions in the ingested fixture.

Accurately isolates specific transaction IDs lacking mandatory documentary references based on tabular completeness rules.

Generates clean Markdown and JSON output formats ready for senior investigator review.

Narratives are purely descriptive without accusatory legal claims or regulatory filing triggers. Examples are simplified synthetic app records. Use mock external writes. Require human review before any real deployment.
