My standard is the only standard to successfully employ tunable, passive tempco employing a heat-equalization pipe. Why didn't you think of that?
errrmahgerd !! a "passive tempco heat-equalization pipe" !!!!
You are most certainly right sir....I would never think of such a ludicrous thing.....I bow and am humbled by such a device.... 
"Tuning" the tempco ? 
Where do you come up with this shit.....
What you do not understand you find humorous, or you revile it.
BTW I am very familiar with passive heatpipe technology
Your are undoubtedly referring to passive refrigeration, which is one application of a heat pipe, and which uses the familiar and cylindrical form of a pipe.
....but explain how a passive heat pipe, "tunes" the "tempco" in a "sealed" enclosure 
Doesn't that TDP have to escape the case somehow? Or does it fly into the "quantum vacuum"? I don't see any heatpipes in the teardown, nor do I see an external path for the heatpipe to transfer thermal energy to a heat exchanger....nor do I see a fan to further remove that energy from the external heat exchanger.....furthermore....why would you want to REMOVE heat?
As I implied above, you hold a parochial view of the term heat-pipe. I'm using a more theoretical-thermodynamic sense of heat pipeing, without the passive refrigeration. I'm just pumping heat as a physical circuit inside a closed system, as a distribution method. Don't confuse my use of the word, "circuit" with the more narrow view of
electronic circuit. There are also
heat circuits used mainly in chemical engineering. I've simply applied the concept for use in my standard.
Does the circuit somehow generate enough heat that it will melt the plastic enclosure? You are familiar with the concept of "ovenizing" these device right?
Ovenizing requires power; power requirements that precludes the use of small, inexpensive batteries for input power.
Heat pipes are designed to transfer heat form one place to another.....usually from a source of heat, to a heat exchanger....I.E. from a let's say a microprocessor to a thermally bonded "pad"....through the heatpipe itself, to a heat exchanger...which is located a distance form the heat source....and usually to a heatsink, with some form of active cooling solution.....I.E. from cpu to external heat exchanger....with some form of active cooling....the purpose is to move heat OUT of the case.....
Another example would be a sodium filled valve-stem.....which is designed to (once again) REMOVE heat from a cylinder head valve seat....
I am a bit puzzled by how a "passive" heat pipe helps stabilize a monolithic voltage ref IC.....usually we want to pump heat INTO them....have you figured out a way to "make heat" passively? That is simply astounding.....I would like to know more. You and the "quantum vacuum" guy must be good friends.....
BTW is this your "heatpipe"? Because that is simply a piece of foil....and it appears you are trying to move heat between some kind of resistor (or diode...I can't tell because it appears you have slathered everything in some type of non thermal adhesive) and the top of the IC package.....sorry but that is NOT a heat pipe....a heatpipe is a hollow (vapor cavity), tubular (sometime oval or "flat" but hollow non the less) device, usually filled with a type of "wick"....
In the most parochial view, yes, what you say is a heatpipe. But in an interdisciplinary sense a heatpipe does not necessarily have a cylindrical shape, nor is it even necessarily hollow. Sometimes it is desirable to transfer heat from one part of a closed system to another, and this is no less the job of a heat pipe than passive refrigeration.
You do also realize you could have done this same thing, by designing a proper PCB, with a common thermal layer...and a REF IC that is in a "can" (TO package), flipped into the "dead bug" configuration.....although I don't really see the point of either....you have no controlled heat source....unless your "heatpipe" is once again aligned with the "quantum vacuum"....
Rather than being freed by your knowledge, you are enslaved by it. If you knew who you are insulting, you would be aghast at yourself. But you assume anything you do not understand is worthy of ridicule, contempt, or is irrelevant.
I have learned what I know first by scientific theory, from which I have developed applications. I am not one who learns at the application level. My self-image in no way depends on my knowledge. If I'm incorrect, so be it! I welcome correction. But is it's only a matter of semantics, I don't really care. If it's something of substance, I welcome it!
still feel like playing? 
Your words ring hollow, because you justify being correct at the expense of broadening your knowledge base. I'm confident, whereas you cling to a narrow view, demanding that it be recognized as the pinnacle of truth, when in fact it is a slice of a bigger picture. And when you introduce malice toward others, you reveal who you really are; not to be trusted.
