Evidence
Lock the product truth
KreoFlow accepts named product assets and source-attributed claims. Referenced factual lines must match their evidence; semantic copy review stays human.

Product evidence → finished vertical ad
A finished ad with a receipt.
KreoFlow is an accountable compiler for product advertising. It constrains the strategy to sourced product facts, renders the validated scene plan, then records what passed and what still needs a human decision.

Required before campaign use
This page is an independent research build. It does not claim a Build Week entry or submission; the current maintainer’s region is blocked by the published eligibility rules.
One inspectable chain
The model proposes. The contract decides.
A persuasive idea is not enough. Each stage leaves an artifact the next stage can validate, replay and reject.

GPT-5.6
Compile a CreativeSpec
GPT-5.6 turns bounded evidence into a typed scene plan. In this public replay, the checked-in fixture replaces a live API call.

Render
Execute, don’t improvise
The renderer follows scene timings, assets, overlays, CTA and sound from the validated spec. The composition can be re-rendered; each encode gets its own exact receipt.

QA + approval
Ship with a receipt
FFprobe and loudness checks create a technical receipt. Human approval stays mandatory for identity, legibility, claims and commercial quality.

claim / best-in-classBlocked
“Best noise cancelling in the world”
No substantiating source supplied. The compiler refuses the line instead of quietly turning a marketing draft into product evidence.
Typed CreativeSpec / fixture replay
A scene plan a renderer can execute.
GPT-5.6’s job is creative strategy inside a schema: angle, promise, timing, asset role, overlay and CTA. It does not get to invent product proof or silently change the delivery contract.
Live mode
The Responses API adapter is ready for a supported, configured environment. This public case deliberately replays the checked-in spec and makes no claim that a live model call produced this page load.

Division of responsibility
Intelligence is useful when its boundary is visible.
Creative reasoning
Interprets evidence, chooses an angle and returns a schema-valid CreativeSpec. A fixture provides the same interface when a live call is unavailable.
System construction
Built the contract, tests, renderer, QA path and this proof surface across the repository. The work remains inspectable in code and commits.
Commercial accountability
Owns the product truth, creative taste, legal review and final approval. KreoFlow does not convert an automated check into permission to publish.
Current boundary
Honest prototype, useful next step.
- NOVA ONE is a fictional spec product, not a client performance case.
- The public route replays a fixture; it does not perform a live GPT-5.6 call.
- Technical QA cannot prove identity fidelity, legality or conversion lift.
- Human review must catch factual copy incorrectly labelled as creative language.
- Provider generation and live product-page ingestion are not part of this proof.
- The current renderer accepts declared PNG, JPEG or WebP stills; video inputs are not implemented.
- The browser brief is still a legacy intake and is not connected to this local render CLI.
- No Build Week submission is claimed while the eligibility blocker remains.
