Dear Ken:
This pull request is not for merge purpose but It's also clean to merge if you want. (Same x37 speed up and pass all 39 tox tests)

I am testing Gemini 3 Pro/Claude Sonnet 4.5 (in AntiGravity IDE) as AI Agent to write the code. This implementation has the same effect as the previous pull. The only difference is that the fast_read is implemented in tight coupling with parse.py, instead of the fast_read bypass ply approach. Hence the psf.py file is relatively clean.
I would like to use this as s transition study from Computer-Aided Design(CAD) to Human-Aided AI Design (HAAD) :p
I will probability close this pull request after 5 days without action
