Help Needed: "Stay Folded" (LVL: Medium/Advanced)

The project: "Stay Folded"

The project name originates from an avatar that I made, that required a "folded" animation to run. The animation was named "folded" and thus the script was named "stayfolded".

While this script has application for boxy/robotic/non-articulated avatars (daleks, etc).. it also has equal application for "holding a teddy bear"..or a sign, or anything that requires an animation to run, and keep running.

Now, I realize there are issues with animation priorities, that simply can't be solved easily.. and the solutions I have found, tend to be worse than the problem. So, for the moment, let's set aside the issue of competing P4 animations.

The issue is simply this.. how do I start the animation "on wear" and then anticipate and deal with, the types of situations that tend to "release" animations (teleporting for example). And how do I reassert the hold/fold animation when it does "get bumped"? I'd like to avoid installing a franimation/zhao AO with the same animation in every slot.

Here's my code, for what I have now. If anyone has any suggestions, please let me know. Am I missing some obvious cases? Am I doing something hideously wrong?

string anim;
integer gotPerms = FALSE;

init()
{
    llSetTimerEvent(0);
    gotPerms = FALSE;
    anim = llGetInventoryName(INVENTORY_ANIMATION, 0);
}

getPerms()
{
    gotPerms = FALSE;
    llRequestPermissions(llGetOwner(),PERMISSION_TRIGGER_ANIMATION);
        // no idea why it splits "TRIGG  ER" like that on the forums.
}

playAnim(integer toggle)
{
    if (!gotPerms) getPerms();
    else
    {
        if (toggle)
        {
            llStartAnimation(anim);
        }
        else
        {
            llStopAnimation(anim);
        }
    }
}

default
{
    state_entry()
    {
        init();
        getPerms();
    }

    on_rez(integer startparam)
    {
        llResetScript();
    }
    
    run_time_permissions(integer perm)
    {
        if(perm & PERMISSION_TRIGGER_ANIMATION)
        {
            gotPerms = TRUE;
            llSetTimerEvent(1);
            playAnim(TRUE);
        }
        else 
        {
            init();
            getPerms();
        }
    }

    changed (integer change)
    {
        if (change & CHANGED_LINK)
        {
            llResetScript();
        }
        
        if (change & CHANGED_TELEPORT && gotPerms)
        {
            init();
            getPerms();
        }
    }
    
    timer()
    {
        integer worn;
        if (llGetAttached() == 0) worn = TRUE;
        else worn = FALSE;
        
        playAnim(worn);
    }
}

two years ago i made the robots Hack & Slash from ReBoot
they required the legs to stay folded this is the script i wrote then

string stand = "StayFolded";
default
{
    state_entry()
    {
        llSetTimerEvent(0.0);
    }
    
    attach(key id)
    {
        
        if (id != NULL_KEY)
        {
            llRequestPermissions(id,PERMISSION_TRIGGER_ANIMATION);
            llStartAnimation(stand);
            llSetTimerEvent(1.0);
        }
        
    }
    timer()
         {   
           llStartAnimation(stand);
         }
}

note: PERMISSION_TRIGGER_ANIMATI ON has the extra space that lindens insist we have in the forums but needs to be removed to work
