Module resolver 

Variable resolution pass - runs between parsing and evaluation.

The resolver walks the AST and transforms unresolved name references into slot-indexed lookups (depth, slot), eliminating string-based name lookups at runtime.

• depth - how many scopes up from the current scope the variable lives
• slot - the index of the variable within that scope’s slot array

Unresolved Identifier nodes become ResolvedIdentifier { depth, slot }. Unresolved Assign nodes become ResolvedAssign { depth, slot, value }. Function and lambda bodies are resolved in their own pushed scope. Import statements are read from disk, lexed, parsed, and resolved inline.

Modules

expressions 🔒

Expression resolution - transforms name references into indexed lookups.

statements 🔒

Statement resolution - transforms declarations and control flow into slot-indexed variants and resolves import statements at compile time.
