patient-web — Prometheus Chains

Web MVP for patient-owned records: anchor plaintext hash on L1 (Ethereum), encrypt & store on L2 (Base), and Restore via wallet-derived keys.

✨ What it does

• Anchor-first workflow: Canonicalize FHIR JSON → SHA-256 → contentHash → append to your PatientRecord on L1.
• Encrypt & store: Derive {tag, key, nonce} from a one-time EIP-712 signature; encrypt with AES-GCM; store ciphertext in the L2 Vault by secret tag.
• Restore: Re-derive {tag, key, nonce}, fetch ciphertext by tag, decrypt locally, and verify SHA-256(pt) == contentHash from L1.
  (Integrity & ordering on L1; storage & privacy on L2.)
  Implementation details match the app code and workflow spec.

🧭 How it works (at a glance)

1. Ensure record (deploy/lookup your PatientRecord).
2. Authorize key derivation (EIP-712 sign → in-memory session root).
3. Anchor on L1 (hash canonical FHIR JSON → anchor(contentHash, l2ChainId)).
4. Encrypt & store on L2 (deterministic tag/key/nonce → Vault.put(ciphertext, tag)).
5. Restore (loop i=1..seq: derive → fetch → decrypt → verify).

# React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh

## Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

```js
export default tseslint.config([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...

      // Remove tseslint.configs.recommended and replace with this
      ...tseslint.configs.recommendedTypeChecked,
      // Alternatively, use this for stricter rules
      ...tseslint.configs.strictTypeChecked,
      // Optionally, add this for stylistic rules
      ...tseslint.configs.stylisticTypeChecked,

      // Other configs...
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])

You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:

// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'

export default tseslint.config([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...
      // Enable lint rules for React
      reactX.configs['recommended-typescript'],
      // Enable lint rules for React DOM
      reactDom.configs.recommended,
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])
