ulp
ULP — Usage Ledger Protocol. A tiny, privacy-first JSON format for what your coding agents cost: tokens, dollars, provenance (billed/estimated/unpriced), and the work they attach to — mergeable across machines with no server, account, or network. Version 1.0, two reference implementations, pure-JSON conformance kit.
