Major Milestone Update: Delivered C2PA Signing, Ed25519 Trust Anchors, COMPLIANCE Lock & Developer Hub

Since our initial submission, we didn't just polish the project — we shipped the exact features listed under "What's Next for Notary", taking Notary from an already strong prototype to a production-grade, enterprise-ready media provenance platform.

Here is what we engineered and shipped in the latest codebase update:

1. Full C2PA Content Credentials Signing & Claim Inspector (Delivered "What's Next" Gap!)

In our original submission, we noted that C2PA embedding was our biggest open target. It is now 100% delivered and verified in code.

  • JUMBF Metadata Injection: Built c2pa_signer.py using c2pa-python to inject standard C2PA JUMBF metadata headers into watermarked assets backed by an X.509 ES256 leaf + root CA certificate chain (es256_certs.pem + c2pa_root_ca.pem).
  • EU AI Act Article 50: Fully satisfies requirement EU-ART50-02 (Machine-readable marking), bringing our compliance engine to a 100% pass score (9/9 checks) across EU AI Act Art. 50 and India IT Rules 2026.
  • C2PA Claim Inspector UI: Built a real-time C2PA claim inspector component into both the internal Asset page and the Public Verification Portal.

2. Ed25519 Independent Digital Signatures & Open Trust Anchor

To protect against unauthorized B2 bucket tampers or compromised storage credentials, we added an independent cryptographic layer in signing.py:

  • Ed25519 Keypair Signing: Every manifest is signed with a high-security Ed25519 private key before B2 write.
  • Open Public Key Endpoint: Public keys are served via GET /.well-known/notary-public-key.pem so third-party auditors can independently verify signature authenticity offline.

3. Steganographic & Visual Watermarking

  • Built watermark.py using Pillow to automatically overlay a pill-shaped visual disclosure badge onto generated images prior to M0 manifest embedding.
  • Fulfills India IT Rules 2026 requirement IN-SGI-02 (Visible labeling) directly in the pixel pipeline.

4. Upgraded Storage Security: B2 COMPLIANCE Mode Lock

  • Upgraded Backblaze B2 Object Lock from GOVERNANCE to COMPLIANCE mode.
  • WORM (Write Once Read Many) immutability is strictly enforced — manifests and assets cannot be deleted or modified during their retention period by anyone, including root storage keys.

5. "Cinematic Developer Noir" Landing Page

  • Built a high-impact landing page at / featuring a 3D WebGL background animation (spinning silver icosahedron with a glowing pulsating orange core).
  • Custom glassmorphism card hover interactions, Lucide React icon integration, and fluid responsive layouts.

6. Interactive Documentation Hub (/docs)

  • Added a full-featured documentation reader at /docs backed directly by our technical specification.
  • Includes a live text search filter, sticky table of contents with scroll-spy, and one-click copy-to-clipboard API cURL code blocks.
