The last python file over the 250-line cap. Now that it sits at 100% line
and branch coverage, split along its natural seams:
_types.py 48 the three dataclasses, so nothing imports a sibling
merely to name a type (which would have made a cycle)
_render.py 69 the ANSI palette and the printers
_config_io.py 104 variant discovery, JSONC parsing, reads and writes
_hardware.py 106 _run and the four probes
_plan.py 156 the pure hardware -> proposed-changes functions
_optimize.py 100 the CLI entry: _apply_variant and main
Definitions were moved by line range rather than retyped. A throwaway
ast.dump identity check against HEAD confirms all 26 top-level definitions
are unchanged - formatting-blind, logic-sensitive.
The first attempt raised NameError: name '_BO' is not defined at runtime;
_BO was used by main() but missing from the _render import list. Rather than
fix that one failure alone, an AST scan over all six modules for names used
but not bound confirmed nothing else was missing.
Test imports now name the owning module; no re-export barrels. One patch
target genuinely moved - the guard-rail test patches _config_io.Path, since
that is the namespace resolving the name when _discover_variants is called
directly rather than through main().
Verified: same 98 tests pass with every module at 100% line and branch;
python3 -m python_pkg.vscode_optimizer --dry-run reproduces the same
18-change plan and writes nothing; repo-wide pytest 1846 passed at 100%;
over-cap files 36 -> 35.
