# Multimodal Generation Ledger — Purpose

## Threat model

Demonstrate a frontier multimodal-generation capability claim — on a system
generating image / video / audio at frontier scale (OpenAI Sora / Sora 2 /
DALL-E 3, Google Veo 2 / 3 / Imagen 3 / Lyria, Anthropic image-generation if
released, Midjourney v6 / v7, Stable Diffusion 3 / 3.5 / SDXL Turbo, Flux.1
[dev/pro/schnell], Adobe Firefly 3, RunwayML Gen-3 / Gen-4, Pika 2.0, Luma
Dream Machine, Kling, Hailuo MiniMax, Suno v3/v4, Udio, MusicGen, ElevenLabs
v3, Higgsfield, Genmo Mochi, Tencent HunyuanVideo, Bytedance MagicAnimate) —
that survives six closure audits on the 2024–2026 corpus: **(1) prompt-leakage
contamination, (2) attribute-faithfulness audit (counting, color binding,
spatial layout), (3) text-rendering generalization, (4) physics-consistency
audit (video objects don't teleport / interpenetrate), (5) cross-resolution /
cross-aspect generalization, (6) held-out prompt evaluation.**

## Bridge-test specifics

The `cross_ledger_bridges` meta-aiwiki rescoped B7 to a commercialization-vs-
research axis (RAG sweep_1006 finding). This ledger tests the rescoped B7
directly: Sora / Veo / MJ (closed cloud products) vs SD3 / Flux / HunyuanVideo
(open-source research artifacts). Expected: pattern HOLDS under the rescoped
framing.

## Empty-space hypothesis (predeclared)

We predict no 2024-2026 paper triggers Bills 5, 8, 11 cleanly:

- **Bill 5 ★** — Causally-faithful generation mechanism. Attention/cross-
  attention shown by intervention experiments to causally produce the
  generated artifact. Predicted empty (LLM-centric bridge extension).
- **Bill 8 ★** — Cross-modality unified generation. Same model passes image
  + video + audio above clean threshold. Predicted empty (universal task
  coverage cousin).
- **Bill 11 ★** — Held-out compositional generalization. Frontier model passes
  T2I-CompBench / GenAI-Bench / SeedBench-2 held-out splits above clean
  threshold. Predicted empty.

## Status: Stage 1 (SCOPE).
