Complete Phase 2: Market Analysis, Filtering & Documentation
This commit implements all Phase 2 functionality with architectural
improvements over the original plan.
## Phase 2.1: Property Valuation Data ✅
- filter_deals_by_criteria() with comprehensive filtering
- calculate_deal_statistics() for statistical aggregations
- _extract_floor_number() for Hebrew floor parsing
- _calculate_std_dev() helper function
- MCP tools: get_valuation_comparables, get_deal_statistics
## Phase 2.2: Market Activity & Investment Analysis ✅
- calculate_market_activity_score() - deal frequency & velocity
* Activity score (0-100), trend analysis, monthly distribution
* Classifies markets: very_high, high, moderate, low, very_low
- analyze_investment_potential() - price trends & stability
* Price appreciation rate via linear regression
* Volatility score using coefficient of variation
* Investment score combining appreciation & stability
- get_market_liquidity() - turnover & liquidity metrics
* Quarterly/monthly breakdowns, velocity scoring
* Trend direction, most active periods
- MCP tool: get_market_activity_metrics (unified tool)
## Phase 2.3: Enhanced Deal Filtering ✅
- Property type, room count, price, area, floor filtering
- All integrated into existing tools
- Hebrew floor number parsing support
## Testing ✅
- Added 15 comprehensive unit tests (all passing)
- Coverage: market activity, investment analysis, liquidity, filtering
- Edge cases: empty data, invalid dates, insufficient data
## Documentation ✅
- Created CLAUDE.md (~250 lines) - AI agent guidance
* Development commands, architecture overview
* Product vision from USECASES.md
* Available tools with status indicators
- Updated TASKS.md - Phase 2 marked 100% complete
## Architectural Improvements
- 1 unified MCP tool instead of 6 separate tools (simpler API)
- 1 flexible filtering function instead of 3 (more composable)
- All logic in govmap.py (no new files, better cohesion)
- ~955 lines added with comprehensive documentation
## Design Principles Followed
✅ MCP provides data, LLM provides intelligence
✅ No predictions - only statistical calculations
✅ Comprehensive error handling & input validation
✅ Well-documented with detailed docstrings
Phase 2 Progress: 100% complete (60% overall project completion)
