Struct DiscoveryPass 

pub struct DiscoveryPass<'a> { /* private fields */ }

Discovery pass that scans tokens before main parsing to build a TypeRegistry.

This pass looks for type definitions in ## Definition blocks:

• “A Stack is a generic collection.” → Generic type
• “A User is a structure.” → Struct type
• “A Shape is an enum.” → Enum type

Phase 50: Also scans ## Policy blocks for security predicates and capabilities.

Implementations

impl<'a> DiscoveryPass<'a>

pub fn new(tokens: &'a [Token], interner: &'a mut Interner) -> DiscoveryPass<'a>

pub fn run(&mut self) -> TypeRegistry

Run discovery pass, returning populated TypeRegistry (Backward compatible - returns only TypeRegistry)

pub fn run_full(&mut self) -> DiscoveryResult

Phase 50: Run discovery pass, returning both TypeRegistry and PolicyRegistry
