Harden Developer ergonomics: what I learned (095)

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

Why I touched it

I forced myself to stop and write the failure mode before touching code.

I kept everything practical by using a short loop around Developer ergonomics.

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

{
  "checklist": ["scope", "timeouts", "telemetry"],
  "owner": "you"
}

I also ran this while working from a family dinner prep for one IRL pass.

What I kept

• This developer ergonomics setup now has a measurable made failures obvious path.
• I keep the same format for every future run.
• If it can be explained in one checklist, it usually scales better.
