Part of Milestone 2 — First Protocol Decoder: LayerZero V2

Tasks

• Integration test: index LayerZero events from testnet, verify messages in PostgreSQL
• Verify cross-chain correlation (PacketSent → pending, PacketReceived → executed)
• Verify Parquet archive on O3 contains expected events and is readable
• Verify cursor persistence across restarts (no duplicates)

Dependencies

• All M2 components: decoder, indexing loop, correlator, archival pipeline

Acceptance Criteria

• Indexer picks up a real PacketSent event and creates a pending message in the database
• Corresponding PacketReceived event updates message to executed with destination details
• Parquet file on Akave O3 contains indexed events and is readable
• Cursor survives restarts: no duplicates on re-run
• Unit test coverage >80% on decoder and normalization code
