Compatibility Targets

Compatibility scope and platform targets for PYRS.

PYRS targets CPython 3.14 semantics as the only correctness baseline. Behavior that diverges from CPython is treated as a bug, not an alternative dialect.

Release Platform Targets

Platform	Priority
`Linux (x86_64)`	Required release target.
`macOS (x86_64 + aarch64)`	Required release target.
`Windows`	Non-priority target for current release cycle.

Runtime Scope

Area	Current Position
Source Language	CPython 3.14 grammar and runtime behavior parity is the target.
Bytecode	CPython 3.14 `.pyc` execution compatibility is in scope.
Native Extensions	Active C-API closure work for scientific-stack and ecosystem compatibility.
