I am testing the right one, just happened SSH_PORTABLE  in version.h 
wasn't update from p2 to p1:

11:11:50 leo at sdf-1 ~/temp $ curl -O 
https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-10.0p1.tar.gz

11:11:57 leo at sdf-1 ~/temp $ tar tzvf openssh-10.0p1.tar.gz | grep version.h
-rw-r--r--  0 djm    djm       172 Apr  9 01:02 openssh-10.0p1/version.h

11:12:14 leo at sdf-1 ~/temp $ tar xzvf openssh-10.0p1.tar.gz 
openssh-10.0p1/version.h
x openssh-10.0p1/version.h

11:13:42 leo at bsdf-1 ~/temp $ cat openssh-10.0p1/version.h
/* $OpenBSD: version.h,v 1.105 2025/04/09 07:00:21 djm Exp $ */

#define SSH_VERSION    "OpenSSH_10.0"

#define SSH_PORTABLE    "p2". <--------
#define SSH_RELEASE    SSH_VERSION SSH_PORTABLE
