🏷️ release tree_haver 🏷️ v4.0.2

4.0.2 - 2026-01-08

• TAG: v4.0.2
• COVERAGE: 95.27% – 2033/2134 lines in 28 files
• BRANCH COVERAGE: 84.07% – 802/954 branches in 28 files
• 95.49% documented

Added

• FFI Backend: Implemented missing? method on TreeHaver::Backends::FFI::Node
  • Added ts_node_is_missing FFI function attachment
  • This method was missing entirely, causing NoMethodError when checking for MISSING nodes

Changed

• TreeHaver::Node: Removed defensive respond_to? checks from has_error? and missing? methods
  • All tree-sitter backends (MRI, Rust, FFI, Java) must implement these methods on their inner nodes
  • This enforces proper backend API compliance rather than silently masking missing implementations

Fixed

• FFI Backend: Added explicit boolean conversion (!!) to has_error? return value
  • FFI :bool return type may behave inconsistently across Ruby versions and platforms
  • Ensures has_error? always returns true or false, not truthy/falsy values
