Tier 2 · Declarative tags.scm

Zig

Declarative tree-sitter query plugin powered by QueryLanguagePlugin (rgctl-lang-runtime) and crates/rgctl-lang-zig/queries/tags.scm. Compiles once at startup, validates captures against the Tier-2 vocabulary gate, and extracts symbols, container hierarchy (Container::member), imports, and call edges.

Capture summary

Capture	Patterns	Graph mapping
@_bi	2	Lexical scope capture.
@definition.class	1	Emits SymbolType::Class (acts as enclosing container).
@definition.constant	1	Emits SymbolType::Constant.
@definition.function	1	Emits SymbolType::Function (acts as caller scope & container).
@import	1	Lexical scope capture.
@import.path	1	Emits SymbolType::Import with normalized import_path metadata.
@name	4	Symbol identifier or target callee/type name.
@reference.call	1	Emits RelationType::Calls from innermost enclosing function to @name.
