Signature, parameters, and return type

/**
 * Opaque previous snapshot returned by `replaceAndGetPrevious`.
 *
 * Only `record` is readable, for recovery or display. Passing the original snapshot object
 * back to `replaceIfBillingKeyMatches` also restores the nonsecret operation fingerprint.
 * The fingerprint and the trusted record are linked only through a module-private
 * `WeakMap`, so JSON copies, spreads, manual reconstructions, or inheriting objects have no
 * registry identity and the lifecycle fence is intentionally false after such a restore.
