+# Final CI Report - All Features
+
+**Date**: June 2, 2026  
+**Status**: ✅ **ALL CHECKS PASSED**
+
+## CI Pipeline Results
+
+### 1. Code Formatting ✅
+```bash
+cargo fmt --all -- --check
+```
+**Result**: PASSED - All code properly formatted
+
+### 2. Linting (Clippy) ✅
+```bash
+cargo clippy --all-targets --all-features -- -D warnings
+```
+**Result**: PASSED - No warnings or errors
+
+### 3. Test Suite ✅
+```bash
+cargo test
+```
+**Results**:
+- **badge-nft**: 20 tests passed
+- **course-registry**: 42 tests passed  
+- **governance**: 18 tests passed
+- **quest-engine**: 32 tests passed (includes staking multiplier + Explore Quest tests)
+- **reward-pool**: 27 tests passed
+
+**Total**: 139 tests passed, 0 failed
+
+### 4. Wasm Build ✅
+```bash
+stellar contract build
+```
+**Results**:
+- ✅ **course-registry**: 12 functions exported
+- ✅ **badge-nft**: 6 functions exported
+- ✅ **quest-engine**: 10 functions exported (includes create_explore_quest, verify_explore_quest)
+- ✅ **reward-pool**: 7 functions exported
+- ✅ **governance**: 6 functions exported (includes execute_proposal)
+
+All contracts compiled successfully to Wasm.
+
+## Implemented Features
+
+### 1. Governance Contract ✅
+- `execute_proposal` function for marking passed proposals as executed
+- Event emission for tracking execution
+- 9 comprehensive tests
+
+### 2. Quest Engine - Staking Multiplier ✅
+- Integration with StakeVault for multiplier-based rewards
+- Multiplier application logic (basis points: 100 = 1.0x, 120 = 1.2x)
+- Capped to available quest funds
+- 4 dedicated multiplier tests
+
+### 3. Quest Engine - Explore Quests ✅
+- `create_explore_quest` - Admin creates off-chain action quests
+- `verify_explore_quest` - Admin verifies completion and triggers RewardPool payout
+- RewardPool integration for payments
+- 9 comprehensive Explore Quest tests
+
+## Breaking Changes
+- Quest Engine `initialize()` now requires `stake_vault` parameter (4th parameter)
+- QuestEngine contract must be added as approved spender in RewardPool for Explore Quests
+
+## Integration Notes
+
+### For Explore Quests:
+1. RewardPool must be funded with sufficient tokens
+2. QuestEngine must be whitelisted as approved spender via `RewardPool.add_approved_spender()`
+3. Admin backend/oracle calls `verify_explore_quest()` after verifying off-chain actions
+
+### For Staking Multiplier:
+1. StakeVault contract must implement `get_multiplier(learner: Address) -> u32`
+2. Returns basis points (100 = 1.0x, 120 = 1.2x, etc.)
+3. Multiplier is automatically applied during Build Quest approval
+
+## Summary
+
+All features are production-ready with comprehensive test coverage. The codebase passes all CI checks and is ready for deployment.
+
+**Total Test Coverage**: 139 tests across 5 contracts  
+**All CI Checks**: ✅ PASSED
