Inversed rotation in navigation while ceiling

Unity Engine

I was to know how works agent rotation betweek animation while walking in ceiling.
I dont know why but the first my agent walks nice in ceiling but i get right now all the time turning on the other side of ceiling

I was set off auto traverse link in agent.
And in late update testing :

 IEnumerator MoveAcrossNavMeshLink()
    {
        OffMeshLinkData data = agent.currentOffMeshLinkData;
        agent.updateRotation = false;

        Vector3 startPos = agent.transform.position;
        Vector3 endPos = data.endPos + Vector3.up * agent.baseOffset;
        float duration = (endPos - startPos).magnitude / agent.velocity.magnitude;
        float t = 0.0f;
        float tStep = 1.0f / duration;
        while (t < 1.0f)
        {
            transform.position = Vector3.Lerp(startPos, endPos, t);
            agent.destination = transform.position;
            t += tStep * Time.deltaTime;
            yield return null;
        }
        transform.position = endPos;
        agent.updateRotation = true;
        agent.CompleteOffMeshLink();
        MoveAcrossNavMeshesStarted = false;

    }


In late update
if (agent.isOnOffMeshLink && !MoveAcrossNavMeshesStarted)
        {
            StartCoroutine(MoveAcrossNavMeshLink());
            MoveAcrossNavMeshesStarted = true;
        }

Also i have found AgentLinkmover in github but i got same issue.
And, to get agent facing in nice direction we can use this in late update
if (agent.velocity.sqrMagnitude > Mathf.Epsilon)
{
transform.rotation = Quaternion.LookRotation(agent.velocity.normalized);
}

That works nice but not while climbing in other surface.

I have made a little video for explain this better, i apologies about my english.

Suggestion to improve that?
Because i cannot find in documentation, with links how to get when im moving to ceiling or floor to do a custom animation.

Im testing some different methods
Trying to get the normal of the surface.
Trying to get endpos - startpos to check if agent is moving up or down.
But i get null when i try to get tag from navmesh link like this:

OffMeshLinkData data = agent.currentOffMeshLinkData;
        agent.updateRotation = false;
        if (data.valid && data.offMeshLink) {
            GameObject go = data.offMeshLink.gameObject;
            Debug.Log(" Name of OffMeshLink GO = " + go.name);
        }

Any suggestion to prevent my agent while moving to ceiling to move to first floor ?
