Abstract

This paper documents MH8-Music-Prompt-Pro, a single-file, dependency-free Single Page Application (SPA) that implements a deterministic provenance protocol for AI music generation prompts. The system introduces six novel mechanisms:

Triple-layer proof-of-creation receipts with embedded SHA-256 cryptographic anchors
Canonical JSON serialization for creative artifact hashing
Continuity-lock mechanism for musical parameter provenance (GENRE/BPM/KEY_SIGNATURE)
Multi-portal structured prompting schema optimized for Suno/Udio platforms
Bracketed hook-pack ingestion and injection pipeline
User-embedded SHA256_ID serialization bridging human tracking with machine verification

The protocol ensures reproducible, timestamped, auditable prompt provenance from human creation through AI generation, addressing a critical gap in AI music workflow transparency.

Keywords: AI music provenance, deterministic hashing, structured prompting, continuity lock, creative artifact serialization, single-file SPA

1. Introduction

AI music platforms (Suno, Udio) accept unstructured prompts combining lyrics, style tags, and production directives. No existing system provides:

Cryptographic proof-of-origin for the prompt itself
Parameter continuity tracking (GENRE/BPM/KEY locking)
Structured multi-layer serialization separating lyrics from metadata
Hook ecosystem extensibility for reusable prompt components
Single-file deployment across all environments

MH8-Music-Prompt-Pro solves these gaps through a protocol-first UI that generates triple-layer receipts:

text

Layer 1: LYRICS → Platform lyrics field
Layer 2: STYLE/TAGS/SETTINGS → Platform prompt field  
Layer 3: HASHED_RECEIPT → Private cryptographic proof

Each receipt contains a deterministic SHA-256 hash of canonical JSON payload:

text

hash = SHA256("MH8-Acbeatz.com|" + stableStringify(core_payload))

2. Protocol Architecture

2.1 Multi-Portal Schema

The system defines 22 canonical portals representing the complete AI music prompt surface area:

text

CORE: MODEL_BEHAVIOR_CONTROL, LYRICS, GENRE, MOOD, ENERGY, VOCAL_INTENSITY
PARAMETERS: ERA_INFLUENCE, BPM, KEY_SIGNATURE
INSTRUMENTS: BACKING_VOX, DRUMS, GUITAR, BASS, PIANO_KEYS, SYNTH, PERCUSSION
PRODUCTION: DYNAMICS, MIX, MASTER
EXTENSION: EXTRA_HOOKS, NOTES, CONTINUITY_LOCK, SHA256_ID

Three tiered flows expose portal subsets:

QUICK: 7 portals (behavior, lyrics, core style, tracking)
SEMI: 19 portals (full production stack)
ADVANCED: 22 portals (complete surface area)

2.2 Triple-Layer Receipt Model

text

LAYER 1 (Platform-ready):
[LAYER 1 — LYRICS (PASTE THIS)]
{raw lyrics text}

LAYER 2 (Platform-ready):  
[LAYER 2 — STYLE / TAGS / SETTINGS (PASTE THIS)]
• [PLATFORM] Suno
• [GENRE] rock
• [CONTINUITY_LOCK] ENGAGED | LOCKED_UTC: 2026-02-16T02:52:52Z | GENRE: rock | BPM: 88 | KEY: A
• [SHA256_ID] b9ac803080cc52ad0c7f09594240f578421f86cddbc49561954a74d2ed2ed39a
[SHA 256 ID + {minted_hash_hex}]

LAYER 3 (Cryptographic proof):
machine_hard: {
  core_payload: {portals, continuity_lock, platform, timestamp},
  canonical_payload: "{frozen JSON string}",
  hash_input: "MH8-Acbeatz.com|{canonical_payload}",
  sha256_hex: "{deterministic hash}",
  cryptographic_receipt_status: "VALID"
}

2.3 Canonical Hashing Pipeline

text

1. core_payload = {
     system: "MH8-Music-Prompt-Pro",
     version: "1.0.0", 
     brand: "ACBEATZ.COM",
     platform: "Suno",
     prompt_name: "Prompt 1",
     created_utc: "2026-02-16T16:15:00Z",
     portals: {LYRICS: "...", GENRE: "...", ...},
     continuity_lock: {engaged: true, genre: "rock", bpm: 88, key_signature: "A"},
     imported_hooks_count: 200
   }

2. canonical = stableStringify(core_payload)  // deterministic JSON

3. hash_input = "MH8-Acbeatz.com|" + canonical

4. minted_hash = SHA256(hash_input)  // crypto.subtle.digest('SHA-256')

Key innovation: The minted SHA-256 hash is serialized back into Layer 2 as the final line, creating a closed verification loop:

text

Prompt → AI Platform → Track → Hash matches Layer 3 → Provenance confirmed

3. Continuity Lock Mechanism

Novel contribution: Parameterized continuity tracking for musical elements.

text

1. DISENGAGED: Normal editing of GENRE/BPM/KEY_SIGNATURE portals
2. ADD_LOCK: Snapshot current portal values → {engaged: true, genre: X, bpm: Y, key: Z}
3. ENGAGE: Lock portals read-only, apply snapshot values, visual LOCKED state
4. Locked portals reject edits, toast "Continuity lock active", re-apply values

Receipt serialization:

text

[CONTINUITY_LOCK] ENGAGED | LOCKED_UTC: 2026-02-16T02:52:52Z | GENRE: rock | BPM: 88 | KEY_SIGNATURE: A

Verification: Any observer can confirm the track's GENRE/BPM/KEY matches the locked snapshot at prompt creation time.

4. Bracketed Hook-Pack Ingestion

Protocol: JSON files containing bracketed strings ([Performance: Emotion | choose 1 word | commit]) are:

Parsed: Bracketed regex extraction → flat array of hooks
Merged: Union of all imported packs → state.hooks[]
Filtered: Pack selector chips toggle between "MERGED" vs individual packs
Injected: Click-to-append into any portal via modal editor

Scalability: Infinite hook packs, deterministic merging, pack-level filtering preserves provenance.

5. Single-File SPA Implementation

Architecture density (97kb minified):

text

- 2000+ lines vanilla HTML/CSS/JS
- CSS custom properties + light/dark theming
- ARIA-complete accessibility (tablist, dialog, status)
- Keyboard navigation (←→ Enter, tab cycling)
- Clipboard API + legacy textarea fallback
- crypto.subtle SHA256 + Uint8Array polyfill
- localStorage vault persistence
- Mobile viewport-fit=cover hardening

No dependencies: Ships as one HTML file. Runs in any modern browser.

6. Prompt Entries Completed (Verification Surface)

Critical UX/protocol bridge: Button exposes Layer 1 + Layer 2 only with:

text

[PROMPT ENTRIES COMPLETED — COPY/PASTE]
INSTRUCTIONS: Copy/paste the two blocks below into your AI music platform.

[LAYER 1 — LYRICS (PASTE THIS)]
{lyrics}

[LAYER 2 — STYLE / TAGS / SETTINGS (PASTE THIS)]
• [PLATFORM] CUSTOM
• [CONTINUITY_LOCK] ENGAGED | LOCKED_UTC: ... | GENRE: rock | BPM: 88 | KEY_SIGNATURE: A
• [SHA256_ID] {user_tracking_id}
[SHA 256 ID + {minted_sha256_hex}]

The final line ([SHA 256 ID + {minted_hash}]) embeds machine-readable verification directly in the human-facing prompt.

7. Verification Workflow

Given a Suno/Udio track with embedded SHA-256:

text

1. Extract Layer 2 final line → minted_hash = "b513cff2c553aeb8..."
2. Reconstruct core_payload from Layer 1+2+user SHA256_ID
3. canonical = stableStringify(core_payload)
4. hash_input = "MH8-Acbeatz.com|" + canonical  
5. computed_hash = SHA256(hash_input)
6. IF computed_hash == minted_hash → PROVENANCE VERIFIED
