Rationale: 50% threshold too permissive for Israeli real estate market.
Within same room count/area, legitimate price variance typically ±30-35%, not 50%.
Example: 13,402 NIS/sqm deal (47% below 25,120 median) was passing with 50% threshold.
This is almost certainly data error or partial deal, not legitimate market variation.
Changes:
- ANALYSIS_PERCENTAGE_THRESHOLD default: 0.5 → 0.4 (40%)
- Update CLAUDE.md docs to reflect 40% threshold
Impact:
- New lower bound: median × 0.6 (was median × 0.5)
- New upper bound: median × 1.4 (was median × 1.5)
- Tighter filtering while preserving legitimate high/low-end deals
- Better aligned with actual Israeli real estate market variance
Tests: All 326 tests pass
