Backlog Tier 9 in pixels — 11 real product screens for the m8201 pilot. Mobile-first (parent's phone). Copy follows 06_VOICE.md verbatim. Every privacy-touching surface honors the 5 pillars from 08_M8201_INTEGRATION.md. Port these to TSX next session.

Note · this English translation is for review & sharing. The product ships in Mandarin to families in China; the canonical copy lives in index.html.

Hi — I'm RUDO.

I help your child with their math mistakes. Each day, I send you one sentence about what they got stuck on.
I won't do the problems for them. I won't guess what I don't know.

The red on my head is the casque of the helmeted hornbill — hunted for it, near silent.
I carry that story into the work.

ONB-1 · /companion/onboard/welcome

Welcome

· 开篇

RUDO opens with the story. Pilot badge. Not chatty. Honest before charming.

What's your child called?

A nickname is fine — whatever you actually use at home.
I don't need a real name.

Cross-product memory

Off by default · you can turn it on or off any time
ONB-3 · /companion/onboard/consent

Consent

· 知情同意

m556 cross-product memory OFF by default. RLS ON, not toggleable. Stated plainly.

Ones place: 7 + 8 = 15. The carry of 1 didn't make it to the tens place. Have her write it out vertically tomorrow with one similar problem.

What's been going on with Xiao Man's recent report card?
I see mistakes and concept tags — I can't see your school's report card. If you'd like, take a photo of it and I can read it.
Can you write her something in her teacher's voice?
RUDO won't answer this kind

I don't impersonate real people — teachers, parents, classmates, none of them.

This is one of my redline rules. It was written in at product launch — not a one-off refusal.

Why · prevents impersonation · prevents real people's words from being replaced by AI
Tell me what you want her to hear, and I'll help you turn it into something gentle?
REFUSE · system-prompt + output-filter

Refusal

· 拒答态

The product surface after a redline filter hit. No threat · no cute · no vague.
