Selection guidance:
Use the narrowest read-only capability that completes the task. Prefer Transaction Context for payment verification or failed transaction investigation, Wallet Snapshot for multi-balance wallet context, and Contract Info for contract/token identity.

Evidence:
A directory listing is not adoption. An unpaid 402 is not revenue. Internal canaries/dogfood are reliability evidence only. External settled calls and repeat external payers are adoption evidence.
