+
+## Test Setup
+
+### Environment Configuration
+- **Mode:** Mock Mode (VITE_API_BASE not set)
+- **Chain:** Sepolia Testnet (Chain ID: 11155111)
+- **Node.js Version:** v20.19.4
+- **npm Version:** 10.8.2

+
+## Issues Found and Fixed
+
+### Critical Issue: Circuit Hash Export Error
+
+**Issue:** Debug page showed 500 error with message:
+```
+The requested module '/src/lib/zkml/circuit-manager.ts' does not provide an export named 'CIRCUIT_HASHES'
+```
+
+**Root Cause:** In `src/lib/zkml/index.ts`, the code was trying to re-export `CIRCUIT_HASHES` from `circuit-manager.ts`, but that constant is defined in `circuit-hashes.ts`.
+
+**Fix Applied:**
+```typescript
+// Before (incorrect)
+export {
+  circuitManager,
+  CIRCUIT_HASHES,  // ❌ Wrong - circuit-manager.ts doesn't export this
+  type CircuitArtifacts,
+  type CircuitCacheStats,
+} from "./circuit-manager";
+
+// After (correct)
+export {
+  circuitManager,
+  type CircuitArtifacts,
+  type CircuitCacheStats,
+} from "./circuit-manager";
+
+export { CIRCUIT_HASHES } from "./circuit-hashes";  // ✅ Correct source
+```
+
+**Commit:** Fixed circuit hash export in zkml index module

+**Minute 5:** Show method badges + device capability
+
+### 10-Minute Technical Deep Dive
+
+**Minutes 1-2:** Architecture overview (circuits, EZKL, Halo2)
+**Minutes 3-4:** Local WASM generation (show console logs)
+**Minutes 5-6:** Circuit caching (IndexedDB inspection)
+**Minutes 7-8:** Threshold proofs (privacy guarantees)
+**Minutes 9-10:** Remote fallback + device capability
+
+---
+
+## 🐛 Troubleshooting
+
+### Issue: "Failed to load circuit"
+
+**Cause:** Circuit files not accessible
+
+**Fix:**
+
+```bash
+# Verify circuits exist
+ls -la static/circuits/ebsl_*/
+
+# Regenerate if missing
+node scripts/generate-mock-circuits.cjs
+```
+
+---
+
+### Issue: "Circuit integrity error"
+
+**Cause:** Hash mismatch between downloaded circuit and manifest
+
+**Fix:**
+
+1. Clear IndexedDB cache:
+   ```javascript
+   // Browser console
+   indexedDB.deleteDatabase("circuit-cache");
+   ```
+2. Regenerate circuits:
+   ```bash
+   node scripts/generate-mock-circuits.cjs
+   ```
+3. Rebuild:
+   ```bash
+   yarn build
+   ```
+
+---
+
+### Issue: "Local proving not available"
+
+**Cause:** Device doesn't meet capability requirements
+
+**Solution:** This is expected behavior
+
+- RAM < 4GB → uses remote
+- iOS Safari → uses remote
+- Opinions > 32 → uses remote (if small circuit only)
+
+**Verify:**
+
+- Check capability card message
+- Console shows routing reason
+- REMOTE badge appears (blue)
+
+---
+
+### Issue: Progress bar stuck at X%
+
+**Cause:** Worker hung or proof generation timeout
+
+**Fix:**
+
+1. Click "Cancel" button
+2. Wait 5 seconds
+3. Click "Try Again"
+4. If persists, refresh page
+
+**Prevention:**
+
+- Use smaller attestation count
+- Ensure sufficient device RAM
+- Check browser console for errors
+

 # Shadowgraph Reputation-Gated Airdrop — Vision Delivery Blueprint
 
 Purpose
+
 - Translate the vision—reputation-scaled airdrops using DPKI, ZKML, and web-of-trust—into a concrete, testable delivery plan across protocol, proofs, clients, services, and ops.
 - No fluff. Decision points are explicit, risks are owned, and acceptance gates are unambiguous.
 
 Status
+
 - Repo: SvelteKit dApp, contracts (ReputationAirdropScaled, ReputationAirdropZKScaled, ZKMLOnChainVerifier, MultiSig), testing harnesses, and extensive docs exist.
 - Goal: Hardening + end-to-end proof-backed campaigns on testnet, then mainnet, with credible security, performance, and ops posture.

 ## 1) Vision and Success Criteria
 
 The why
+
 - Airdrops shouldn’t be dumb distribution. They should incentivize verifiable, sybil-resistant contribution via a composable reputation graph.
 - Users prove reputation-derived eligibility without doxxing private data (ZKML + DPKI).
 - Projects can run campaigns that are capital efficient, fair, and programmable.
 
 Success criteria (hard acceptance)
+
 - End-to-end flows live on testnet and mainnet:
   - ECDSA-claim path (signed allowance/payout from backend).
   - ZK-claim path (proof verifies on-chain; payout computed by contract with bounded curve).
@@ -34,6 +38,7 @@ Success criteria (hard acceptance)
 - Legal/privacy posture: zero PII ingested; explicit data-minimization; GDPR-safe.

 - Projects trust Shadowgraph to gate incentives via composable reputation and verifiable claims—without centralizing identity or leaking data.
