@0gflow/core

The primitives every other 0G Flow package agrees on. Zero dependencies.

RFC 8785 canonical JSON, with the number formatting spelled out
sha256, keccak256 and secp256k1 recovery, hand-written
Receipt encoding and hashing, pinned against Solidity by a cross-language vector
Chain-root folding
Attestation binding levels — absent / present / attested / bound
Agent output signatures
The success rule, in one place

Hand-written rather than pulled from libraries because the verifier has to stay a single auditable file and the same code has to run in a browser. It can recover a public key and deliberately cannot sign: code that cannot sign cannot leak a key.

decideStepStatus is the only function permitted to produce a step status, and a structural test fails the build if anything else tries. No status reports success unless a third party could confirm it from public data.

Where this fits

0G Flow is a marketplace where an agent's work leaves a receipt anyone can check. Browse it at https://explorer-production-25c8.up.railway.app.
