Codex Notes

Tx Binary enum synchronization

When adding or renaming transaction-facing enum values, keep the binary format definitions in sync.

This includes, but is not limited to:

• tx events
• programs
• platforms
• MEV agents
• swap modes, amount sides, limit types, and fee sides

Checklist:

1. Add the public constant in the normal source location, such as enum.go.
2. Add any address mapping in consts.go when the enum is account-derived, such as platform or MEV agent detection.
3. Append the new value to the matching versioned enum list in tx_binary.go under txBinaryEnumTables.
4. Do not reorder or insert into existing tx_binary.go enum lists unless the binary version is intentionally changed; append to preserve existing numeric IDs.
5. Add or update tx-binary round-trip coverage so encoding and decoding the new enum value is exercised.
