 ## What's Next
 
-Phase 3 Plan 1 complete. Ready for Phase 3 Plan 2: Hardware tier detection and management system.
+Phase 3 Plan 2 complete. Ready for Phase 3 Plan 3: Proactive scaling with hybrid monitoring.
 Phase 3 requirements:
 - Detect available system resources (CPU, RAM, GPU) ✓
-- Select appropriate models based on resources
+- Select appropriate models based on resources ✓
 - Request more resources when bottlenecks detected
 - Graceful scaling from low-end hardware to high-end systems
 
-Status: Phase 3 Plan 1 complete, 3 plans remaining.
+Status: Phase 3 Plan 2 complete, 2 plans remaining.

+# Phase 3: Hardware Tier Detection Summary
+
+**Hardware tier classification system with configurable YAML definitions and intelligent model mapping**
+
+## Performance
+
+- **Duration:** 4 min
+- **Started:** 2026-01-27T23:29:04Z
+- **Completed:** 2026-01-27T23:32:51Z
+- **Tasks:** 3
+- **Files modified:** 3
+
+## Accomplishments
+
+- Created resource management module with proper exports and documentation
+- Implemented configurable hardware tier definitions with comprehensive thresholds
+- Built HardwareTierDetector class with intelligent classification logic
+- Established model recommendation system based on detected capabilities
+- Integrated with existing ResourceMonitor for real-time hardware monitoring
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create resource module structure** - `5d93e97` (feat)
+2. **Task 2: Create configurable hardware tier definitions** - `0b4c270` (feat)
+3. **Task 3: Implement HardwareTierDetector class** - `8857ced` (feat)
+
+**Plan metadata:** (to be committed after summary)
+
+## Files Created/Modified
+
+- `src/resource/__init__.py` - Resource management module initialization with exports
+- `src/config/resource_tiers.yaml` - Comprehensive tier definitions with thresholds and performance characteristics
+- `src/resource/tiers.py` - HardwareTierDetector class implementing tier classification logic
+
+## Decisions Made
+
+- Three-tier classification system provides clear boundaries: low_end (1B-3B), mid_range (3B-7B), high_end (7B-70B)
+- YAML configuration enables runtime adjustment of thresholds without code changes
+- Integration with existing ResourceMonitor leverages enhanced GPU detection from Plan 01
+- Conservative fallback to low_end tier ensures stability on uncertain systems
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None - all components implemented and verified successfully.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Hardware tier detection system complete and ready for integration with:
+- Proactive scaling system (Plan 03-03)
+- Resource personality communication (Plan 03-04)
+- Model interface selection system
+- Conversation engine optimization
