📋 Step C: Idempotency + Partial Failure Recovery (Step 4)
🔁 Philosophy: Retries Don't Corrupt
If a dev retries due to timeout, you don't duplicate or corrupt. Systems must be safe to retry.
4.1 Store Idempotency
Send same request twice with same idempotency_key → same memory_id or "already exists"
4.2 Extract/Embed/Ingest Idempotency
Re-run stages multiple times → no duplicate graph nodes, no duplicate edges, no double-counting
4.3 Partial Failure Recovery
Simulate: Store succeeds, Extract fails → rerun pipeline → completes cleanly without corruption
🔁 Step C: Idempotency + Retry Safety
Philosophy: Retries don't corrupt. Failures recover cleanly.
What we're testing:
- Store idempotency → same request twice = no duplicates
- Pipeline idempotency → re-run Extract/Ingest = no double-counting
- Partial failure recovery → Store succeeds, Extract fails → rerun cleanly
- Metadata deduplication → only one metadata record per bottle
- Graph deduplication → fingerprinting prevents duplicate nodes
Goal: Prove the system is safe to retry under any failure condition.
