Reference

Reference material answers a different question from the learning material: what behavior is defined, and where is that definition owned?

Language reference — map the normative Core v0.1 specification and its ownership boundaries.
Standard library — navigate the library families present in the source revision consumed by this website.

The Protos repository remains the authority for observable syntax and semantics. This website curates and navigates that material from an exact locked source revision; it does not independently redefine the language.
