 **Token** -- Represents a private token balance. Implementations may add additional fields beyond `owner` and `amount`:

 **Merkle non-inclusion proofs** are required only on transitions where the sender is private -- **`transfer_private`** and **`transfer_private_to_public`**. Transitions where the sender is public -- **`transfer_public_to_private`** and **`transfer_from_public_to_private`** -- check the sender against the freeze list directly via **`is_frozen_address`** (or the equivalent **`verify_non_inclusion_pub`** helper).
 
 **Compliance coverage.** Every transition that moves balances on a private path -- **`transfer_private`**, **`transfer_private_to_public`**, **`transfer_public_to_private`**, and **`transfer_from_public_to_private`** -- emits a **`ComplianceRecord`** owned by **`INVESTIGATOR_ADDRESS`**, so the investigator can decrypt the full sender / recipient / amount tuple whenever at least one side is private.
