Each module answers one question: Does it exist? (Pulse), Is it normal? (Baseline), Is it regular? (Timing), Is it trending? (Drift), Which sensor to trust? (Consensus), How to handle overflow? (Pressure), What do we do about it? (Mode).
Every module is closed (no dependencies), total (handles all inputs), deterministic, and O(1). 83 tests passing.
Built this after 30 years in UNIX systems. Wanted something that teaches the rigour behind certified systems without requiring a decade of on-the-job learning first.

Were LLMs used to produce some of the writing? Not sure how to describe it, but it has a certain recognizable writing style (e.g. "The Problem"/"The Solution", lots of bulleted lists with bolded first words, etc.) Readers might appreciate if AI use is disclosed.
I've built certified systems (munitions), and the pain of certification is almost always in the process not the coding.
The process is expensive, rigorous and lengthy. It's the process that certifies something good enough to get the stamp for release, not the code design or architecture.
int64_t age = now - then; // UNDEFINED BEHAVIOUR if overflow!
uint64_t age = now - then; // DEFINED: wraps at 2⁶⁴
Seriously, fuck C. Since this book focuses on safe, reliable, bugfree programs, why not use Rust?Anyhoo... seems interesting. I've been trying to convince Claude to produce a verified JavaCard VM implementation, just for the hell of it, and this probably has a bunch of information to help with that.
