How open-source are these glasses really? Are all software components compilable from source, or do they just publish an SDK Espressif-style?

It's all open-source:

Not really, despite the repo being named MentraOS, this repo seems to include only some mobile apps (that either run on a phone or on the glasses), some server code, and some SDKs. Mentra glasses are likely running on a fork of AOSP, which is not in this repo.

AOSP (or even a minimal fork) is way too heavy to be running on the glasses. It looks like the firmware is quite minimal and the "OS" is the app.

Most smart glasses just run AOSP, that's the path of least resistance. Ones without displays are often just Bluetooth headsets in shape of eyeglasses, and only the ones with cameras but not displays are the ones that run a lightweight OS.
