#311 Harden financial health score arithmetic and normalization
Description
This PR implements issue #311: hardened financial health score arithmetic and normalization for the reporting contract. The changes ensure secure, tested, and documented score calculations with bounded outputs under extreme inputs.
Changes
calculate_health_scoreinto modular helper functions for better maintainabilitySecurity Improvements
✅ Overflow protection with saturating arithmetic
✅ Safe division preventing panics on edge cases
✅ Bounds checking on all score components
✅ Edge case handling (zero targets, negative amounts, extreme values)
✅ Deterministic output independent of ledger state
Testing
Build Status
✅ Compiles successfully for WASM deployment
✅ All tests pass
✅ No breaking changes to existing functionality
