The 9 Dimensions

MHAIX scores human creative authorship across nine weighted dimensions. Each dimension produces a 0–100 sub-score; sub-scores are combined by weight into a single 0–100 result, which maps to one of five tiers (H-5 Predominantly Human → A-1 AI-Generated).

Disclosure is never a penalty. Honest answers about AI use produce a more accurate verdict and a more defensible certificate. Total weights below sum to 100.

The Nine Dimensions at a Glance

The D4 Floor — Composers and Producers Aren't Penalized

Not every creator performs on their own tracks. A composer who writes and hands the parts off, or a producer who builds a track entirely in the box, doesn't tick many of the "played it live" boxes in Dimension 4. That's fine.

D4 has a built-in floor: even with zero live-performance answers, your D4 raw score never drops below the floor. It only goes up from there when you can attest to performed parts. This is deliberate — composition-first and production-first paths are valid, and neither is treated as inferior to a live-performance path.

The Iteration Journal — D7's Bonus Track

On the D4 step you'll see the Iteration Log (a.k.a. Iteration Journal). It's a timestamped list of the versions you went through to reach the final take: what you generated, what you changed between takes, and — optionally — why the previous version didn't work.

The Iteration Log feeds directly into scoring for D7 (Iterative Creative Labor). Each logged iteration adds up to +3 points to your D7 raw sub-score, and each iteration where you filled in a "why the previous version didn't work" note adds another +1 point. The bonus is capped at +20 points total to D7 raw. Because D7 is weighted in the overall verdict, that feeds through to a meaningful lift — while still keeping the ceiling honest.

You don't have to fill it in to complete the assessment. It's optional evidence: the more iteration you documented, the stronger the D7 story your certificate tells.

Evidence Attachments on Iteration Entries

Each entry in the Iteration Log can carry two optional attachments — an audio file(mp3, wav, or m4a, up to 25 MB) and a screenshot(png, jpg, or webp, up to 5 MB). Screenshots also accept paste — focus an entry and press ⌘V / Ctrl+V to drop in whatever's on your clipboard.

Attachments are capped at 10 audio and 10 screenshots per certification session (shared across all entries). They're purely optional supporting evidence for the D7 iteration bonus described above — nothing about your score requires them, but they make the iteration story on your certificate substantially more defensible.

D8 and D9 Are Scored on Completion, Not Content

Dimensions 8 (Training Data Provenance) and 9 (Commercial Intent) are disclosure-only. You are scored on whether you completed the questions truthfully — not on which platform you picked or which options you chose.

Concretely: picking a "yellow" or "red" risk-tier platform on D8 does not lower your MHAIX score. Choosing sync licensing on D9 does not lower your score. You may see an advisory banner if certain combinations are known to complicate downstream licensing (e.g. sync + an elevated-risk platform), but advisories are guidance, not point deductions.

The whole point is honest, complete disclosure. A track that discloses AI use fully and accurately produces a more defensible certificate than one that hides it.

AI Platforms in the D8 Registry

The Training Data Provenance step recognizes the following platforms. Each is tagged with a current risk indicator (Green / Yellow / Red / Gray) so you can see the licensing landscape at a glance — again, tags do not affect your score.

Don't see the platform you used? Pick "Other" during D8, then use the request-a-platformbutton to submit its name (and any context). Every gray-platform request is logged for our review team so we can extend the registry over time — you'll still be able to finish and download your certificate in the meantime.

The Veridem Authorship Registry

Every finalized MHAIX certificate is automatically registered with the central Veridem Authorship Registry — a shared verification database used across all Veridem products (MHAIX, Stem:Ample, Re:Writ, Compose:EP). At the moment you finalize, the app calls the registry, receives a unique registry ID, and embeds it into the certificate along with a scannable QR code that links to a public verification page. Anyone holding the PDF can scan the QR to confirm the certificate exists in the registry and matches what's on the page.

Cryptographic Signing (Ed25519)

At finalization, the certificate payload is hashed and signed with a freshly-generated Ed25519 keypair. The signature and the public key are embedded in the certificate itself, and a short signing key fingerprint is printed on the document so it can be visually cross-checked. This proves the certificate hasn't been altered after issuance — any tampered copy will fail signature verification.

Metadata Fields — PRO, IPI, Publisher, ISRC / ISWC, Samples

MHAIX collects a handful of optional industry-standard metadata fields alongside the authorship questions. Every one is optional — you can finalize a certificate without any of them — but filling them in makes the resulting PDF substantially more useful downstream (registration with a PRO, distributor onboarding, sync pitches, sample clearance conversations).

PRO / IPI / Publisher — on the Creator step and on each Co-Author you add, an optional collapsible section lets you record the songwriter's Performing Rights Organization (ASCAP, BMI, SESAC, PRS, SACEM, GEMA, etc.), their IPI (Interested Parties Information) number, and whether the writer share is self-administered or handled by a named publisher. This is the same information a PRO or publishing administrator will ask for when the song is registered; capturing it on the certificate keeps split and administration details attached to the authorship record.

ISRC / ISWC — on the Song Info step, two optional fields let you attach an ISRC (International Standard Recording Code, identifying the specific recording) and an ISWC (International Standard Musical Work Code, identifying the underlying composition). If you already have them from your distributor or PRO, entering them here means the certificate can be matched to the recording and the work by ID rather than by title alone.

Sample clearance toggle — a single Yes/No control asks whether the track contains third-party samples (loops, breaks, interpolations, or any audio you didn't originate). If you mark samples as present, the certificate surfaces a plain-language reminder that sample clearance is your responsibility and that an MHAIX certificate does not clear third-party rights — it only attests to your own authorship of the non-sampled material. This is guidance, not a score deduction.

The Distributor Disclosure Summary

On the results screen you'll see a Distributor Disclosure Summary panel. It's an auto-computed, plain-text block generated from your D1 (composition), D2 (lyrics & vocals), D3 (production), and D8 (platform) answers, mapped onto the five categories defined by the DDEX AI disclosure standard that most major distributors and DSPs now expect:

• AI-Generated Vocals — derived from your D2 vocal-source answer.
• AI Instrumentation — derived from your D3 stems / instrumentation answer.
• AI Composition — derived from your D1 melody / harmony answer.
• AI Post-Production — derived from your D3 mix / master answer.
• AI Lyrical Content — derived from your D2 lyric-authorship answer.

Each category is reported as Yes, No, Partial, or N/A (for example, an instrumental track reports N/A for the vocal and lyric categories). A Copy for distributor button copies the whole block — including the track title and supporting context like commercial-rights tier and one-stop status — to your clipboard, ready to paste directly into a distributor's AI-disclosure form.

The panel also shows a CD Baby / Downtown Music compatibility note. Their current policy prohibits content created wholly or primarily by AI, so fully AI-generated tracks are not accepted for distribution through those services. Tracks with substantial human authorship generally are — but you should always read your distributor's current terms yourself. The note on the summary is a heads-up, not a legal opinion.

Autosave and Cloud Sync

You don't need to finish the assessment in one sitting. As you complete each step, your progress is saved automatically to this browser — refreshing the page, closing the tab, or losing your connection mid-way will not lose your work. Reopen MHAIX on the same device and you'll pick up where you left off.

If you enter an email address during the flow, your session also syncs to the cloud under that email. That means you can resume on a different device (or recover the session if your browser storage is cleared) by returning with the same email. Cloud sync is opt-in — no email means local-only, and nothing about scoring or finalization requires you to provide one.

The Verdict Tiers

• H-5 Predominantly Human (85–100) — overwhelmingly human authorship.
• H-4 Substantially Human (70–84) — human authorship dominates with AI assist.
• M-3 Collaborative (50–69) — meaningful contributions from both human and AI.
• A-2 AI-Assisted (30–49) — AI core, human shaping and curation on top.
• A-1 AI-Generated (0–29) — primarily AI output with minimal human authorship.
