Tighten Schema design: what I learned (112)

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 Schema design.

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

• Capture real inputs
• Check timeout behavior
• Track latency before and after
• Add follow-up reminder

Snippet

- [x] define constraints
- [x] codify outcome
- [ ] iterate on exception path

I also ran this while working from a weekend camping test for one IRL pass.

What I kept

• This schema design setup now has a measurable cut manual work path.
• I keep the same format for every future run.
• If it can be explained in one checklist, it usually scales better.
