Build an Execution Receipt Wrapper for LLM API Calls

Short summary

A practical guide to wrapping LLM API calls with execution receipts that capture latency, validation status, and completion state without storing raw input/output. The author recommends append-oriented, versioned records and separating content access behind its own retention policy. The approach provides enough evidence to reconstruct feature execution while minimizing data exposure.

• •Execution receipts capture latency, contract validation, and status for LLM calls
• •Keep raw input/output out of receipts; store under separate authorization policy
• •Use append-oriented, versioned records for easier later reconstruction
