Below is a two‑part deliverable:
- Part 1 – Idiomatic, production‑ready C++ that re‑implements every observable behaviour of the original assembly listing while eliminating all implementation‑dependent details (inline asm, IDA temporaries, platform thunks, etc.). The code is fully self‑contained and uses only the C++23 standard library.
- Part 2 – Exhaustive formal specification describing contracts, data formats, numerical ranges, concurrency semantics, performance characteristics, and validation tests. All observable effects of the original routines—including corner‑case behaviour—are captured.
