The SDK is runtime, so a full copy of binaries from /usr that the build
runs with. Typically a runtime is defined as a name and version, like
"org.gnome.Sdk" / "3.20". However, once built we record the resolved
manifest in the resulting binary, and that captures the exact commit of
the SDK that was used for the build. This is an OSTree commit, so its
basically a sha256 merkle hash of the entire binary tree.
So, if you keep that around it should be 100% reproducible and
verifiable.

Your project has as a goal to make all software reproducible. I agree
that this is a good goal, and in fact an important one. However, what i
mean by the above is that we have other goals to, such as "wide use of
flatpak for cross distribution binaries and sandboxing". We don't want
to block these goals by demanding reproducible software, as this raises
the barrier further for users.
However, we *can* add tools and recommendations to make reproducible
builds easy.

Flatpaks are stored in ostree, which is structurally basically git, so
I've tried "ostree diff" a few times to see what changed, and its often
not a lot. I haven't done any systematic checks though.
As an example, i built https://git.gnome.org/browse/gnome-apps-nightly/
tree/org.gnome.Maps.json twice, using --disable-updates (to get the
same git commits from the build) and the same build of the sdk.
This is what ostree reports:
$ ostree diff --repo=repo app/org.gnome.Maps/x86_64/master app/org.gnome.Maps/x86_64/master^
M /files/lib/libical.so.1.0.1
We can then generate tarballs for diffoscope:
$ ostree export --repo=repo app/org.gnome.Maps/x86_64/master > build1.tar
$ ostree export --repo=repo app/org.gnome.Maps/x86_64/master^ > build2.tar
Notes:
* The mtime difference does not matter to flatpak/ostree, as they
will be zeroed out on installation. That is why ostree diff didn't
report it.
* Its unclear why libical built differently the second time.
