Phase 5 implementation in Python — language idioms, tooling, and project layout. Composes with a component skill (dev-be/dev-cli/dev-batch). Use when: the stack is Python, implementing a component skill in Python, or setting Python tooling (venv, packaging) and layout.

The Python language layer (idioms, tooling, layout) that composes under a component skill — the component owns what, this owns how in Python.
Use with a component skill (e.g. dev-be for a service, dev-batch for a job) — the component
skill says what to build; this says how in Python. Follow
../../resources/conventions/python.md.
Delegate craft depth to the expert. For real Python idioms, type-system, async, packaging, and
test patterns, load and follow the vendored python-pro expert (see
../../resources/expert-skills-map.md). This skill keeps
owning the harness wiring (persona, conventions, handoff, gates); python-pro supplies the depth.
