'Debugging turns into archaeology rather than engineering', this is the exact realization that forced me to stop building agents and start building a database kernel.

I spent 6 months chasing 'ghosts' in my backtests that turned out to be floating-point drift between my Mac and the production Linux server. I realized exactly what you said: if state isn't replayable bit-for-bit, it's not engineering.

I actually ended up rewriting HNSW using Q16.16 fixed-point math just to force 'reality to line up' again. It’s painful to lose the raw speed of AVX floats, but getting 'Engineering' back was worth it. check it out(https://github.com/varshith-Git/Valori-Kernel)
