“Prove your track isn’t AI.” — what artists are told in 2026
ACTA records the gesture before the file — an artist-held provenance protocol for music composition.
SEE THE PROOF CHAIN ↓“How to prove your song isn’t AI before a distributor pulls it.”
— the practical literature reaching working musicians, 2026
Read that sentence again. The burden of proof has been inverted.
Deezer alone reports more than 60,000 fully AI-generated tracks arriving every day — on the order of a third of its uploads. The response has been detection, flagging, takedowns, retroactive royalty clawbacks. An artist releasing music today is presumed synthetic, and must assemble a defense: archived sessions, witness emails, absence scans against proprietary watermarks.
Disclosure is not neutral either. Platforms are introducing lower royalty tiers for AI-flagged work — the honest declaration the system demands is also a confession that costs money.
WHAT THE PLATFORM SEES
an isolated file — undefendable
WHAT THE STUDIO KNOWS
a topology of making — evidence by construction
DETECTION
“Does this file look synthetic?”
Population-level inference. An arms race by construction — false positives against legitimate work, and a counter-industry already selling artifact removal to defeat it.
DECLARATION
“Trust me, I made it.”
Self-reporting. Unverifiable when honest, free to fake when dishonest, and structurally biased against the declarant.
ACTA
“Here is the signed trajectory of how it was made.”
Attestation of continuity, anchored to the individual baseline. No verdict on an isolated file — a work situated inside the artist’s own documented trajectory.
There is no style model anywhere in the protocol. Style is not proof.
Three layers of evidence, one layer of output. Each layer is independently useful; the probative force is the bundle.
Signature at the point where sound becomes data: the analog-to-digital conversion. The interface computes rolling hashes of the incoming stream, signs them with a device key, timestamps the result. Leica and Canon already sign at the camera sensor — no equivalent exists in audio today. Driver-side attestation activates the installed base; hardware attestation secures the next generation.
The production session is already the process record — it has simply never been signed. A generated track imported as a finished clip and a composition built layer by layer leave structurally different topologies. Nothing needs to be detected; the shape of the session is the evidence. Events are extracted into a canonical vocabulary, built into a Merkle tree, and the root is signed with the artist’s key.
Signed snapshots accumulate in a registry held by the artist — locally — and are anchored with RFC 3161 timestamps. The proof lives in the registry, not in the released file: it survives metadata stripping, re-encoding, platform transcoding. A single session can be fabricated; a multi-year anchored trajectory cannot. The longitudinal baseline is not a bonus feature — it is the security mechanism.
DDEX AI fields, AI Act transparency notices, and any future regulatory disclosure are generated automatically from the attested log. The artist never fills a checkbox again — the declaration becomes a projection of evidence rather than a confession. The label is a feature of the tooling, not a burden on the artist.

}A generative model inside a session is an instrument — like a synthesizer or a mastering chain — and it is traced as one. The distinction preserved is evidentiary, not moral: augmentation under substantial creative control versus autonomous generation. That is the line on which rights now depend.
The studio should produce proof by default.
We do not ask drivers to weave their own seatbelts.
We build them into the car.
No platform.
No distributor.
No model vendor.
Signing keys and registry remain with the artist. Local first. No platform, label or vendor in the custody chain.
Merkle paths make partial proof native. You can prove a track was built layer by layer, with real takes, through an attested converter, on a given date — without revealing a note, a stem, or a collaborator’s name.
LOOPBACK REPLAY
Generated audio played through an attested converter acquires a capture signature — true, and anticipated. It produces a session with no antecedent MIDI, no takes, no incremental construction, sitting inside a trajectory it must also counterfeit. No single layer is absolute proof; the bundle is the claim.
SESSION FORGERY
Faking one project file is easy. Faking a sequence of externally anchored snapshots whose timestamps precede the forgery’s motive is not. The registry raises the cost of fraud from minutes to years.
WHAT ACTA DOES NOT CLAIM
Not a detector. Not a certificate of artistic merit. Not a legal determination. ACTA produces process evidence aligned with the substantial-creative-control standard — tribunals and offices weigh it. Validation requires deployment with consenting artists, under pre-registered protocols.
