+# 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.
