What's in the ZIP
EU AI Act Code of Practice on AI-content marking (3 March 2026 second draft) translated into a 2-page implementation checklist. Every required field, every threshold, every fallback path.

Pick a SynthID-class invisible-watermark library (DeepMind SynthID for Google models, StableSig for Stable Diffusion, custom for in-house). Recipe shows where to insert in the model output layer, threshold tuning, survival testing matrix.
PostgreSQL schema + indices for the Code-of-Practice fingerprinting fallback ledger. Drop into your DB. Includes pHash + dHash columns + sample queries for fuzzy duplicate detection.
Signed Article 50 conformity attestation JSON template. HMAC-SHA256, public verify URL, dated to 2 August 2026 cliff. Plug your entity name + signing key + paste into your evidence pack.
20 ready-to-paste deployer-disclosure-copy templates per Article 50(4): chatbot 'this is AI', deepfake video overlay, emotion-recognition kiosk notice, public-interest text watermarks. EN + DE + FR translations.
Watermark survival test matrix: screenshot, JPEG re-save, platform re-encode (Twitter, LinkedIn, Substack, Discord), 4× upscale, crop, rotation. Score each by % retained on your watermark library.

Frequently asked
Why only £99 when the full /article-50-kit is £999?
The £999 kit ships in 7 days with hands-on integration support + signed attestation generation tied to YOUR entity. The £99 starter is templates + recipe + checklist that you self-deploy in 2 hours. If you have a competent engineer + 2 hours, the starter does it. If you want it done for you with auditor-grade signatures, the £999 kit is the upgrade.
Does the £99 kit include the signed attestation cert?
It includes a TEMPLATE for the signed conformity attestation. You sign it yourself with your own HMAC key. The £999 kit signs it via meok-attestation-api with a public verify URL. The template is sufficient for self-attestation; the signed cert is sufficient for auditor-verifiable evidence.
What format is the kit?
Single ZIP file (~5MB) with the 8 files listed. PDFs are printable; templates are JSON / SQL / Markdown / CSV. After you complete the £99 Stripe checkout, you're redirected to the download URL automatically.
Refund?
14-day refund if the kit hasn't been deployed (no signed cert generated yet). After deployment, no refund — you have the working artefact. UK Consumer Rights Act 2015 statutory protections apply.
Do I still need to write code?
Yes. The kit is templates + recipes + checklists, not a turnkey runtime. You'll plug it into your existing GenAI pipeline (Stable Diffusion / Comfy / OpenAI / Anthropic / custom). Estimated 2-4 hours of engineering for an experienced ML engineer. The £999 kit removes the engineering work.
Will this satisfy my auditor?
The kit produces the artifacts your auditor will ask for (C2PA manifest, watermark survival test results, fingerprint ledger, signed attestation). Whether your auditor accepts your self-attestation versus requiring our cryptographically-signed-via-our-API attestation is auditor-specific. Most auditors accept self-attestation if the artefacts are complete; some Big-4 firms want third-party signatures (the £999 + £4,950 SKUs).
