There are many times in fiction, Star Trek or otherwise, that you have to accept that there are rules that make those fictional worlds work even if they aren't always directly, explicitly stated to the camera for the benefit of the audience.
Throughout DS9, there are many, many stories where changelings infiltrate not just the Federation, but the Romulans and Klingons, as well.
In order for those stories to work, given everything we know about how technology in Star Trek works, we have to accept that changelings can, in fact, make perfect copies of people. Otherwise, given the existence of incredibly sophisticated sensors and tricorders (among other devices) which are literally everywhere in the Star Trek universe, such infiltrations flatly could not happen at all.
We simply have to accept this.
However, this is not one of those times when we have only our assumptions (logical and consistent though they may be.)
The show actually friggin' tells us how changelings work directly and explicitly and we see it working again and again and again.
Wrong. From, "The Adversary":
EDDINGTON
I wish the internal sensors were on-
line. It'd make it a lot easier to
track down the changeling.
ODO
I'm not sure sensors would help. If
you scan me when I'm a rock, you'd
detect a rock. I may not be able to
duplicate a humanoid perfectly, but
I'm guessing he can.
BASHIR
(confirming)
When we scanned "Ambassador Krajensky"
for tetryon particles, he registered
as human.
Uh, yeah. Because Odo normally doesn't have those organs because he's not actively trying to imitate anyone (and probably couldn't even if he tried, as he isn't as skillful a changeling as the Founders.)
Yes, from what Odo was when he's being his normal self. Not when he's a Founder deliberately imitating someone on a spy mission.
Yes, changeling ability to create perfect copies is, in fact, established time and again across many episodes.
Haha, no. It's the showrunners not doing the research. It's perfectly fine if you, as a fan, doesn't remember specific details from a 20 year old show.
It's not fine that the showrunners of a franchise don't do the research and break well-established rules, without which those old stories wouldn't have been able to exist.

You’re making up something that isn’t specified in the shows prior.

when Odo was turned into a human as punishment for killing the infiltrator on the Defiant it was made a clear line of dialog that Bashir could now detect organs, heart, lungs, etc.
Uh, yeah. Because Odo normally doesn't have those organs because he's not actively trying to imitate anyone (and probably couldn't even if he tried, as he isn't as skillful a changeling as the Founders.)
This means that it was a clear departure from what he was.
Yes, from what Odo was when he's being his normal self. Not when he's a Founder deliberately imitating someone on a spy mission.
it was never stated in any episode prior that the Changlings could imitate human or other species physical properties and biology.
Yes, changeling ability to create perfect copies is, in fact, established time and again across many episodes.
what you’re saying is an example of the showrunners not understanding the ds9 Changlings isn’t based on what you have seen on screen, but instead what you assumed and made absolute
