Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. buildConstVariableStatement constructs a const variable statement with initialized value and validates it with isVariableStatement
  2. buildLetVariableStatement constructs a let variable statement with optional type annotation and initializer
  3. buildMultiVariableDeclarationStatement constructs a statement declaring multiple variables in a single list
  4. inspectVariableStatement extracts declaration names, modifiers, and node kind metadata using AST type guards
