v3 Capstone

Full pipeline

• lex -> parse -> analyze -> compile -> encode -> decode -> run
• VM runs decoded artifact only

Boundary contracts

• parser/analyzer output must match compiler input contract
• compiler output must be serializable and decodable
• decode errors stop execution
• no stage reads internal data from neighbors

Closures and collections

• nested function capture remains valid across compile boundary
• arrays/maps pass as heap-backed runtime objects
• closure call expects callable runtime value

Determinism

• same source should yield stable artifact shape
• same source should produce stable run result
• each CompileAndRun gets fresh VM state

Error ordering

• parse/lex first
• first analyzer diagnostic
• compile/encode then decode
• runtime only for fully validated artifacts

Practical checks

• capture visibility and return values
• map/array construction + index write/read
• decode failure blocks runtime
• call to non-callable value errors at runtime
