# Phase 15 Idempotency and Duplicate Report

**Date:** 2026-06-25  
**Status:** Local static design reviewed; production gate blocked

## Summary

The current process-local store coalesces repeated keys, caches non-retryable results, removes retryable failures, and contains no personal data in keys. It is explicitly test/local only.

## Executed evidence

- Historical Phase 14 integration test covered repeated transport.
- Source review confirms retryable failures release the key.

## Unexecuted or blocked evidence

- Current integration/browser retry execution.
- Distributed durable store, late vendor success, cross-instance duplicate policy, legitimate later request policy.

## Release disposition

P14-004 blocks scaled production.
