The indexer-service was incorrectly storing V2 (Horizon) receipt CollectionId values in the
database by truncating them from 32 bytes to 20 bytes. This caused TAP agent database notification
parsing to fail.

Root Cause:

In crates/service/src/tap/receipt_store.rs:348-350, the DbReceiptV2::from_receipt() function was
calling .as_address() on the CollectionId before encoding:

let collection_id = thegraph_core::CollectionId::from(receipt.message.collection_id)
    .as_address()  // ❌ This truncates 32-byte CollectionId to 20-byte address
    .encode_hex();

Solution

Remove .as_address() call to store the full 32-byte CollectionId

Is this correct?
