Months of static analysis, two real bugs

If a config file has more than a dozen options, half of them aren't being used. The other half are being used in ways the original author didn't predict.

The team I learned the most from didn't have great tools. They had a great habit of reading each other's pull requests in full, including the parts that weren't theirs.

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.

I trust monorepos more in the second year than I did in the first. Most of the early friction goes away once the tooling catches up.
