Voice Performance Rights and Provenance

Last updated: October 9, 2026

1. How Mystrix records voice rights

Mystrix records the rights source for the voices assigned to a published Story. The three performance-rights tiers below explain who holds performer consent. Publication checks the active licence against the Story's scope and seals the permitted public cast information with that release. Generated voice audio also carries a machine-readable provenance marker.

This policy explains those rights in the dedicated legal area. Story detail and player surfaces do not display platform licensing notices over or alongside Story content.

A cast credit appears only when the licence's scope permits public credit. Permission to use a performance does not by itself grant permission to name the performer, so a Story can record its rights tier while omitting a person's name.

2. Licensed library

A licensed-library voice comes from an upstream voice vendor. The performer-consent chain is held through that vendor. Mystrix does not hold the library performer's consent directly. Mystrix records the vendor, rights-instrument reference, territory, term, and the exact licence version used for the voice.

3. Mystrix performer

A Mystrix-performer voice comes from a performer who granted Mystrix a sealed, scoped licence. Mystrix holds that performer's consent directly for the uses the active licence permits. Voice and likeness are separate media rights: granting one does not grant the other. The scope can limit rating, program form, content, territory, term, named Stories, public credit, and post-mortem use.

Consent and withdrawal

Performer consent is separate from account registration. Declining or revoking it does not remove ordinary Reader or Creator account capabilities. A submitted recording or image still requires its own provenance, safety, and technical review before it can be offered to creators.

A performer can revoke consent from their performer account surface without a support ticket. Revocation stops new server-side voice synthesis, new likeness imports, and new Story publication using that licence, and deletes matching server-side cached voice clips and pending synthesis bookings. Suspension, expiry, and changes to the permitted scope also prevent new use where the current licence no longer permits it.

Withdrawal cannot recall media already downloaded to another device. It does not rewrite media, credits, use records, or payments already sealed into a historical published Story.

4. Synthetic performer

A synthetic-performer voice is attested as not derived from and not recognisable as any identifiable natural person. There is therefore no natural performer whose consent Mystrix could hold directly. Mystrix records the attested derivation and never uses this tier as a fallback for unknown provenance.

5. Creator-supplied exact performances

A creator may attach their own managed recording to one line in a locked Story beat. Before attaching it, the creator must identify the performer, state whether they performed it or hold permission from the performer, and explicitly confirm the displayed rights statement. Mystrix seals that attestation to the exact audio-byte digest and exact line-text digest.

Editing or unlocking the script invalidates the line binding. It does not rewrite the recording or silently transfer the attestation to different words. A creator-supplied attestation is not a Mystrix-performer licence and does not put the recording into the licensed library.

6. Documentary and course contributions

Licensed expert testimony in a documentary or course is a contributor use, not a fictional cast role. Publication checks the exact contribution version, credential evidence, topic, rating and program scope, selected recording segments, attribution, and pinned performance licence. It then seals the public-safe contributor information and disclosure with that release.

Documentary reader surfaces display that historical disclosure rather than re-resolving a mutable catalogue entry. Before an instructional session delivers selected testimony for an unlocked lesson, it rechecks the current contribution, credentials, Story and topic scope, and performance licence before returning those exact audio or video segments.

A later withdrawal blocks new qualification and instructional segment delivery without erasing an already-published credit, use, or payment record. Performer and payee identities are not inferred from the public contributor attribution.

7. Credits, licence changes, and questions

Performer names shown in a public cast come from the exact licence version sealed at publication. A licence that declines public credit produces no performer name in the public projection. A later licence edit creates a new version; it does not rewrite the historical story projection.
