The service manual describes how to replace the piston without disassembling. There is no torque spec in the manual; the bolts are not shown except as little shadows in the pictures. "Tighten the crap out of them" is never the correct answer.
It is made in two pieces for manufacturing simplicity, then bolted together before final machining.
This is a Volvo caliper and is different than the standard MZ3 caliper. It is possible the dealer mech you spoke with is not familiar with it.

well in the past there are alot of peices that have been screwed together on cars for decades,example: everything-even wheels..and they all stay together just fine. that thing slid right off and back into place prefect there was no glue, seal, etc. And 'tighten the crap out of them" may not work for you but it works for me. That thing is bolted down buy 4 big long bolts, fits perfect i don't see it falling off.
What would the process be for getting the brake pads out, if you don't want to unbolt the caliper bracket from the hub (2 17mm bolts) and you don't want to take apart the caliper (4 allen/star bolts) .... is it this:
1) Take plastic caps off back of caliper
2) Unbolt two allen/star bolts in the plastic housing
3) Disconnect retaining spring on outside of caliper (the rectangle with arms thing you see when looking directly at caliper)
4) Slide caliper out from bracket
5) Slide out old pads
6) Slide in new pads
7) Execute steps 4-1
Would that cover it?

my caliper had no plastic caps, and think according to the instructions you take the 2 midlle star bolts out i just took out the top ones cuase it looked easier for acsess to the pads. Its prob just as esay to just take the 2 middle ones out.
You are probably fine. I hope you have no problems, it is just that this is not the way Mazda & Volvo intended for it to be done.
Just think about all the parts of your car; what is the single most important part? Every single part of the car can fail, but if you still have brakes, you can still stop; no other sub-system matters as much.
Are you sure you only took out four star bolts? When I looked at the caliper last night there were four bright and shiny star bolts. There were also two star bolts surrounded by black plastic right next to the piston housing. In your 8th picture you can clearly see where those star bolts come out. It's a black ring on the right side of the piston.
Point being the four star bolts on the edge of the caliper hold the two caliper pieces together while the two with plastic around them hold the caliper to the bracket <- Is this the correct assumption?

to me it would much more likely for a properly bolted wheel to fly off for no reason for that thing to come loose. I does look like its probly esier to just take the 2 bolts out though.

don't mess withthe plastic ones atleast i didnt, it might be esier to just take off the 2 middle star bolts i thought it was eseay taking off all four and just sliding it out, but if i would have known (i didn't read the instructions) I prob would have just taken the peice off whole and replaced the pads, though i do not think its a big deal to take it apart just screw it back correct and tight, thers no seal,glue or anything nothing leaks out and it fits back on like a glove.

You are a danger to yourself and others. I have tried without success to explain to you why this is a bad idea. It is a critical joint in a critical system not meant to be disturbed and you have no clue what the torque should even be. You have been called on this in at least two different forums by different people and have responded with acrimony and misspelled rants.
I stand firmly with Rotus and strongly advise everyone to follow the factory prescribed method of pad replacement instead of disassembling the caliper.

you are full of BS!!! it does not endanger anyone bolts don't just come off for no reason!!! your car wheel is likely more likely to fly off for no reason, you are being paraniod!! that caliper is held together by 4 huge bolts. "oh a couple of bolts where unscrewed and them screwed back now its unsafe" your theory is juat a bunch of bs hype!!!
