Module environment 

Non-executing PEP 723 discovery and deterministic Python environment plans.

This module is intentionally side-effect free. Parsing never imports provider code, and planning never creates a virtual environment or contacts a package index. A later cache manager consumes the immutable plan.

Structs

Pep723Metadata

PythonEnvironmentPlan

PythonRuntimeFingerprint

Immutable identity of the selected Python runtime and wheel target.

PythonWheelTag

One expanded compatibility tag selected from an SDK wheel filename.

Enums

PythonEnvironmentError

Constants

ENVIRONMENT_PLAN_VERSION

Cache-policy schema version used by immutable Python environment plans.

Functions

parse_pep723_metadata

Parse the PEP 723 script block without importing or evaluating the source.

plan_python_environment

Produce an immutable cache plan. This function performs no filesystem I/O.
