I'm Juan. I've spent 15+ years making records between Buenos Aires and the U.S., founded Panacea Studio along the way, and have worked on about 110 releases since 2022 (credits verified). Now I research how to prove who made what, at the moment it's made.
The short version: detection guesses, provenance proves. I write the papers, then build the small open tools that test them: Sealed Record, a public provenance ledger where every note I publish is signed and appended, rights signals serving one machine-readable AI rights position at the edge, a connector for TypeSafe Jev with typed, confidence-scored answers for WordPress, and Signal & Noise + tools, the brutalist theme and plugin behind juanlentino.com.
Sealed Record checks a sealed session record end to end: hash chain, Ed25519 signatures, time receipts, and whether an audio file is the take it claims to be. No account, no server. Prefer a browser? Drop a record here.
Prefer the terminal? Verify the sample record in three commands.

Reading list: start at the provenance hub: the whole argument, in plain language. Then the papers on SSRN: Provenance Over Detection · Provenance as Substrate · Provenance Without Institutions. Or the notes: shorter essays on the same questions.
