v1.16.2

• Tool descriptions say what rpc_failure means. insumer_attest, insumer_wallet_trust, insumer_verify, insumer_check_discount, insumer_acp_discount and insumer_ucp_discount each state that an rpc_failure error (503) means a read did not complete, nothing was signed, and the call should be retried: it is never a "no". insumer_batch_wallet_trust states the same for its per-wallet error entries. SKILL.md carries the same guidance.
• The merchant tools offer only the wallets the API reads. insumer_verify, insumer_check_discount, insumer_acp_discount and insumer_ucp_discount take wallet, solanaWallet and xrplWallet. The Tron, Stellar and Sui wallet fields are removed from these four tools; the API never read them there. insumer_attest and the trust tools are unchanged.
• insumer_configure_nfts carries enabled and benefitType. A collection that was switched off stays off when its configuration is saved again, and a collection can be recognition only (benefitType: "recognition", no discount).
• insumer_configure_tokens carries name and logo for each token, and enabled (true or false) for the own token.
• Discounts are whole numbers. The descriptions state that tier and NFT discounts are whole numbers from 1 to 50 and discountCap is a whole number from 1 to 100. The schemas already required integers.
• XRPL taxon is an integer from 0 to 4294967295 on insumer_attest and insumer_configure_nfts.
• insumer_attest accepts a Sui coin type with type parameters, such as 0x2::coin::Coin<0x2::sui::SUI>, up to 600 characters.
