+# Directory architecture for AI-generated content with IPFS and wallet-based auth
+
+Below is an organized structure that aligns your current architecture with decentralized content storage (IPFS/Filecoin) and serverless authentication via user wallets. It keeps your static app clean, separates blockchain and storage concerns, and preserves data contracts.

+
+## Data and auth flow in practice
+
+- **AI generation:**
+  - **Trigger:** content_creator_ui.js calls ai_integration.js.
+  - **Validation:** schema_validator.js ensures outputs match lesson/quiz/exercise schemas.
+  - **IPFS publish:** ipfs_integration.js uploads JSON/image to pinning_client.js, receives a CID.
+  - **Manifest update:** Manifests in data/manifests/* are updated with CID, version, and metadata.
+  - **On-chain anchor (optional but recommended):** blockchain_integration.js writes the CID hash/URI to ContentRegistry for immutability and provenance.
+
+- **Content retrieval:**
+  - **Discover:** UI reads manifests or queries ContentRegistry for latest CID.
+  - **Fetch:** gateway_client.js resolves CID via configured IPFS gateways, with **content_cache.db** as client-side cache.
+  - **Render:** lesson_ui.js, quiz_ui.js, exercise_ui.js render validated content.
+
+- **Serverless auth with wallets:**
+  - **Connect wallet:** authentication.js uses wallet_integration.js to connect (e.g., Polkadot.js or MetaMask).
+  - **Identity:** user is identified by public address; actions are signed via private key.
+  - **Authorization rules:** authorization.js checks roles/ownership via on-chain state (e.g., isCreator, hasReward).
+  - **Protected actions:** auth_middleware.js gates actions like “publish to IPFS” or “claim reward” behind wallet connection.
+
+---
+
+## File changes and responsibilities
+
+- **config.json**
+  - **IPFS:** gateway URLs, pinning service API keys, timeout/fallback strategy.
+  - **Blockchain:** network names, RPC endpoints, contract addresses, chain IDs.
+  - **Security:** allowed content types, maximum sizes, versioning policy.
+
+- **js/logic/ipfs_integration.js**
+  - **Upload:** stream-safe JSON and image uploads, receive CIDs, handle retries.
+  - **Download:** gateway resolution, integrity checks via hashes, caching.
+
+- **blockchain/contracts/**
+  - **ContentRegistry:** map content IDs to CID/URI, version, owner, timestamps.
+  - **RewardToken/RewardRegistry:** mint/distribute rewards based on learning events.
+
+- **data/manifests/**
+  - **Purpose:** lightweight pointers to decentralized content for fast indexing and UI listing.
+  - **Versioning:** track latest CID per content item and previous history.
+
+- **auth and UI**
+  - **authentication.js:** wallet connect, signature challenges for session-like UX.
+  - **content_creator_ui.js:** one-click flow: generate -> validate -> publish -> anchor -> update manifest.
+
+---
+
+## Critical review of the new structure
+
+- **Strengths**
+  - **Clear separation of concerns:** AI, storage (IPFS), blockchain, and UI each have dedicated modules.
+  - **Decentralization-first design:** heavy content off-chain with an on-chain anchor ensures integrity without prohibitive costs.
+  - **Auditable publishing pipeline:** validation before IPFS, optional on-chain anchoring, and manifests for fast lookup.
+  - **Serverless auth:** wallet-based identity removes central auth servers and aligns with Web3 norms.
+
+- **Risks and trade-offs**
+  - **Gateway dependencies:** relying on public IPFS gateways can introduce latency or availability issues. Mitigate with multi-gateway fallback and local cache.
+  - **Content moderation and updates:** immutability complicates corrections. Address via versioned CIDs, deprecation flags in manifests, and role-based publishing.
+  - **User experience friction:** wallet connection can deter non-crypto-native users. Offer a guest mode with read-only access and progressive onboarding.
+  - **Security considerations:** exposing pinning API keys in client-side apps is risky. Prefer serverless functions with scoped tokens or restricted capabilities, or use wallet-based delegated publishing where possible.
+  - **Complexity creep:** adding blockchain + IPFS increases operational complexity. Keep interfaces minimal, document data contracts, and maintain integration tests.
+
+- **Practical recommendations**
+  - **Manifests as first-class:** treat data/manifests/* as your canonical index; the chain is the anchor, IPFS is storage.
+  - **Role-based publishing:** only wallet addresses with a “Publisher” role can anchor new content; others can propose drafts.
+  - **Light client strategy:** avoid turning users into full nodes; rely on trusted RPCs with verification where feasible.
+  - **Monitoring:** add simple telemetry to error_log.txt and optional anonymous metrics to detect gateway failures and UX pain points.
