Approved single-module Python now compiles to deterministic ES modules through the validated front-end IR. A dependency-selected helper closure preserves Python integers, Unicode code points, tuples, truthiness, evaluation order, definition-time defaults and source-located errors. Module initialization remains in source order.
The in-memory artifact includes source maps, explicit exports/imports/notices, compiler/profile identities and complete output hashes/sizes. The createModule factory gives browser adapters a text sink and explicit typed input boundary. The shared text_metrics example executes under emitted JavaScript without an interpreter or server fallback.
Validation: 60 Python tests, including CPython/Node output/error/side-effect parity, Unicode/surrogate distinctions, recursion/defaults, negative boundaries, deterministic manifests and Node source-map consumption. Wheel/sdist built with the declared uv backend. Existing package 0.1.0 is not republished; local modules and browser host integration remain their following tasks.
Depends on #29. Closes #13 after merging to main.
