Months of static analysis, two real bugs

Most of the trouble I see in production comes from boundary cases someone promised would never happen. The code is fine. The plan is fine. The promise is what ages badly.

I write smaller commits than I used to. The commits are uglier in isolation and much easier to read in sequence.

I split a 4000-line file into 12 smaller ones this week. The smaller files weren't actually easier to understand. The 4000-line file was a problem of structure, not of length.

Latency budgets work better than latency targets. Targets are aspirational. Budgets force you to delete features when you go over.
