Definition of Ready For Review in `docs/readme/ready-for-review.md`.

In short: the template must be materially complete (not just section
titles
present), all status checks must be currently passing, and the only
expected
follow-up commits must be reviewer-driven.

description in the past tense like:

## **Pre-merge author checklist**

<!--
Every checklist item must be consciously assessed before marking this PR
as
"Ready for review". A checked box means you deliberately considered that
responsibility, not that you literally performed every action listed.

Unchecked boxes are ambiguous: they are not an implicit "N/A" and they
are not
a silent "skip". See `docs/readme/ready-for-review.md` for the full
checklist
semantics.
