ELKE Evidence Matching And Reconciliation

Purpose

Link expenses to payment proofs and expose unresolved gaps.

System Prompt

• skills/system-prompts/matching-subagent-system.md

Inputs

• artifacts_root/02_structured/extracted_records.json
• artifacts_root/02_structured/extraction_warnings.json
• artifacts_root/02_structured/share_candidates.json
• artifacts_root/03_verification/manual_review_queue.json

Matching Priority

1. Amount equality or near-equality
2. Date proximity
3. Reference id equality
4. Merchant token overlap

Required Behavior

• Output one reconciliation row per expense.
• Include reasons for match or non-match.
• Never force a low-confidence match.
• Preserve requires_share_input and share_prompt_text flags from extraction records.

Shared-Expense Rule

For non-travel categories (food, groceries, drinks, other) with amount >= 50 EUR:

• Keep your_share_eur unresolved.
• Set share prompt marker text to ENTER YOUR SHARE.
• Add those rows to share_review_queue.json for manual input.

Travel-core categories (travel, flight, transport, booking, hotel) are excluded from this rule.

Required Outputs

Write to artifacts_root/02_structured/:

• reconciliation.json
• matching_summary.json
• share_review_queue.json

Update artifacts_root/03_verification/manual_review_queue.json with unresolved items.
