Rework Postmortem habit: what I learned (063)

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 Postmortem habit.

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

- [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 postmortem habit setup now has a measurable improved mean time to fix path.
• I keep the same format for every future run.
• If it can be explained in one checklist, it usually scales better.
