PREWAVE-BE-052 — Make Event Ingestion Idempotent by Canonical Log Identity #652
Description
Problem context
Source audit identified this distinct API production-readiness boundary.
Technical scope
Use chain/release/block hash/tx hash/log index and decoder version as canonical identity; handle removed logs explicitly.
Required tests
Duplicate batch, overlapping poll, restart, removed log, same tx multiple logs, and wrong-release tests.
Acceptance criteria
- Reprocessing cannot duplicate effects.
- Removed logs enter rollback flow.
- Identity uniqueness is enforced in storage.
- Decoder version is traceable.
Constraints
Canonical finalized contract events remain authoritative. Bind chain data to chain/release/artifact provenance; fail closed on stale, ambiguous, unauthorized, or incomplete state. Do not weaken CI or expose secrets/protected data.
Dependencies
- PREWAVE-BE-001 — Establish a Canonical Finalized-Block Ingestion Cursor #596
- PREWAVE-BE-003 — Implement Reorg Rollback Journal and Canonical Reconciliation #598
Non-goals
Unrelated work, mainnet deployment, or applying Stellar Wave before maintainer activation.
Complexity and points
- High — 200 points
Candidate only; activation remains maintainer-controlled.
