A working notebook. What I built, broke, read, and thought about — short entries, written close to the moment. Not a log. Just the notebook.
Spent the morning wiring an in-memory LRU cache in front of the model router so identical stack traces don't re-bill us every time. Saw cost drop visibly by lunch. The boring kind of win that I like the most.
Modules should be deep. The chapter on information hiding kept rhyming with my own code from last week — half my files leak implementation through their interface. Going to refactor the email-template module tomorrow with this in mind.
Cleaned up the multi-step lead form. Removed two fields the client never used and added autosave on blur so partials still land in the CRM. Conversion will tell on next week.
Trying to swap a fragile regex-based parser in MedCap for a strict JSON schema response. The diff in correctness is significant; the diff in cost is also significant. Need to think about which queries deserve it.
Took the laptop off the desk and put my notebook back on it. Funny how a week of pen-on-paper makes the next sprint feel sharper. The CPU needs a sleep mode too.
