Sources & reasoning
HLF's detailed reimbursement requirements explicitly call for threshold-based automatic approval. Phase 2 in §5 lists threshold-based approval as part of Reiserefusjonshåndtering, so target_release is Core Product.

Responsibilities
- Load active rules and evaluate them against each submitted claim
- Apply combined conditions (amount ceiling, distance ceiling, receipt presence, expense type, claimant history)
- Mark matching claims as auto-approved and record the rule that fired for audit
- Pass non-matching claims through to the manual approval queue
- Execute dry-run simulation of a draft rule across historical claims and return match statistics
