Prefer narrow interfaces
A service is easier to operate when its public surface is smaller than its internal one.
FIELD NOTES · 2026
Quiet systems are built deliberately.
Short observations about dependable infrastructure, useful defaults and keeping small services understandable.
Make limits explicit
Memory, concurrency and retry budgets belong in the design, not in an incident report.
Keep changes reversible
Independent components and validated configuration make routine maintenance uneventful.
