Struct ContextBuilder 

Source 
pub struct ContextBuilder { /* private fields */ }
Expand description

Token-budgeted context assembler.

Retrieves facts via hybrid search, ranks by tier priority, fills a token budget greedily, and returns a ContextBlock ready for LLM prompt injection.

Implementations§
