I sincerely apologize for this.

I had this doubt on sending an incremental patch or V5:

Yes, patch 1/2 is unchanged and patch 2/2 is the only change.
The diff looks larger due to code movement but logic is actually simpler now.

I completely understand if you prefer to keep V4 and defer this

know what you'd prefer and I'll follow your guidance.
Thank you for your patience.
