Cryptographic inclusion proof for YOUR wallet balance in the latest hourly transparency attestation (GET /wallet/balance-proof): leaf hash, Merkle sibling path, root, the anchoring BSV txid, and verification (the steps to recompute the root and check it on chain). Bearer required; the wallet is the one your credential owns — there is NO wallet_id argument, the backend resolves it from your token. Anchoring is batched exactly like transparency_latest: bsv_txid may read "pending" until this attestation's OP_RETURN transaction is broadcast (usually within minutes; longer when the network is busy) — not-yet-batched is not unanchored; for the most recent anchored root read transparency_latest.last_anchored.
