📝 Walkthrough

Walkthrough

The change updates the sig-approvers-pb alias membership and removes per-proto approver filters. All proto files now use the fallback sig-approvers-pb approver group.

Changes

Proto ownership routing

Layer / File(s)	Summary
Update proto approver alias OWNERS_ALIASES	The sig-approvers-pb alias removes yudongusa and adds likidu, hbisheng, and zhaoshangzi.
Apply fallback approver routing proto/OWNERS	The per-proto filters are commented out. The .* fallback now assigns all proto files to sig-approvers-pb.

Poem

A rabbit checked the owners list,
And found new names to add.
The proto paths now share one gate,
With fallback rules well clad.
“Hop!” said the rabbit, “reviews align!”
