[SC-HARD-18] Safe Fixed-Point Math & Invariant Bounds Engine

[ayomideadeniran]

📋 Hard & Advanced Production Epic

Identifier: SC-HARD-18 | Complexity: Hard / Advanced

⚙️ Specifications & Architectural Breakdown

• Compounded Sub-Tasks: [Easy: Replace raw + with checked_add] + [Medium: Replace raw * with checked_mul] + [Advanced: Fixed-point math arithmetic library with 18-decimal precision, overflow guards, and explicit typed error reporting].
  • Target Files: contracts/continuous_bonding_curve/src/lib.rs, contracts/lending_pool/src/lib.rs
  • Overview: Replace raw arithmetic operations with audited fixed-point and checked math routines, preventing overflow exploits and integer panics.
  • Acceptance Criteria: Arithmetic calculations never panic in WASM; extreme inputs return typed math error enums.
