ProofStream

This bridges the gap between AI agents and physical verification by letting you dispatch actual humans to check things in the real world. You'd reach for this when your agent needs to confirm something exists, verify a condition, or validate physical state that can't be determined remotely. Think confirming a storefront is open, checking if a package was delivered to the right place, or verifying equipment status on site. The implementation details are light, but the concept is straightforward: your agent makes a request, and ProofStream routes it to a human verifier who reports back with confirmation. Useful for any workflow where digital certainty requires analog eyes.
