Clearsigned — the trust layer with no stake in the outcome
Clearsigned — the trust layer with no stake in the outcome. Submit {claim, evidence[]}, receive an Ed25519-SIGNED, evidence-bearing receipt (verify offline against GET /pubkey; every receipt is chained in the public ledger at GET /ledger/verify). Flat price, verdict-independent; refunds only for failure to deliver. Current mode is honestly labeled in each receipt.
