Stabilize Testing strategy: what I learned (050)

I used this as a focused experiment, and I wrote it down while it was still fresh.

Why I touched it

I ran this as a small loop: baseline, change, metric, repeat.

I kept everything practical by using a short loop around Testing strategy.

Implementation notes

I started with a narrow goal: keep the same behavior, reduce one risk, and keep rollback trivial. I moved from vague ideas to explicit rules before touching production paths.

Validation checklist

• Confirm ownership and blast radius
• Add one failing test
• Verify a rollback path
• Remove temporary debug logic

Snippet

set -euo pipefail

node --version
npm ci
npm run lint
npm run test

I also ran this while working from a evening walk for one IRL pass.

What I kept

• This testing strategy setup now has a measurable reduced false positives path.
• I keep the same format for every future run.
• If it can be explained in one checklist, it usually scales better.
