Minecraft Bedrock Edition default blocks

Is there any documentation of the original Minecraft blocks behavior JSON? I’m not looking for blocks.json, I’m looking for individual vanilla blocks and their components such as stone.json, glass.json, etc. I can’t find it in the Vanilla Behavior Pack, and poking around the apk file doesn’t seem to be helping either. It would be really helpful as a guideline when making custom blocks in addons.

Thank you for your time.
