Description

The three open items blocking 20260913-2310 are answered:

1. The AC-side controller is YBO's own, and belongs to the Core line as its DO control member.
2. The boundary "YBO 无任何硬件承载交流载流或交流电位" still holds — the DO member drives DC coils and reads dry contacts across the terminal block, exactly as Core channels did.
3. Core's pulse-output requirement is kept, carried by the DO member instead of the general-purpose Core S/M/HD channels.

Together with the unified Mate, write these into PRODUCT-PLAN.md, COMPLIANCE-MATRIX.md, OPEN-QUESTIONS.md and the affected product directories, then remove the divergence warning from the product index.

Scope is a relabelling of ownership and execution subject, not a new specification: no channel count, current rating, price, milestone or enclosure figure is invented for the DO member. Every such value stays explicitly undecided until the user sets it.

Acceptance: no controlled document still states that a general-purpose Core S/M/HD channel drives AC contactor coils; no document still presents Mate as two halves; the pulse-output requirement survives against the DO member; the AC compliance row still reads "YBO 侧无 LVD 范围"; the warning block is gone; bun run docs:build and git diff --check pass.
