Enum WalletReadSource 

pub enum WalletReadSource {
    Db,
    Fallback,
}

Which tier answered a wallet read (dig_ecosystem#2233).

A node serves a wallet read either from its own chain replica or from a third-party HTTP oracle, and the two are not interchangeable to a caller: the oracle path is a network round trip that discloses the queried address off-node, which a user on a metered or private connection has a legitimate interest in knowing about. Reporting the tier is also what makes “the node answered from its own chain state” a falsifiable claim — a sync-progress flag is not, since a flag can flip while the oracle keeps answering.

Variants

Db

The node’s own local chain replica. No third party was consulted.

Fallback

A third-party coinset HTTP oracle. The queried value — an address, or a COIN ID on control.wallet.coinById — was disclosed off-node.

The coin-id case is the more sensitive of the two, and the less obvious: an address is disclosed on every routine balance poll, whereas querying a freshly created coin id, from the spender’s IP, at the moment of the spend, hands the oracle a {IP, timestamp, coin id} tuple that ties a network identity to a specific new on-chain identity.
