setenv.bat (and activate_venv/get_cmd/install_py.bat) had a UTF-8 BOM,
which cmd.exe read as part of the @echo off line, breaking every bin
script that calls setenv.bat via `call`. Stripped the BOM.
material_flow.bat/.sh and tro_flow.bat/.sh now check up front whether
the Graphviz engine --tosvg needs (dot, or neato with --use-cords) is
resolvable, and print an early WARNUNG with fix instructions if not -
before the CSV is even parsed. The Python scripts still run and report
the same failure in detail if the SVG step is actually reached.
A bank of gravity lanes between the same two Kreisel (same slope) was
drawn as one box per lane, making large storage banks unreadable.
render_dot now collapses such lanes into a single Gefaellestrecke-styled
block with a double border, labelled with the id range and combined
Separator/Scanner ranges. Purely visual - the graph, --doc report and
--connect output still list every lane individually.
lib/scl_skeleton.py and lib/tro_extract.py already run the pipeline
end-to-end (annotated DXF -> TRO-JSON -> FB_Main SCL skeleton), but
CLAUDE.md and README.md still described these as unwritten tools
(tro_export.py / scl_gen.py). Update the current-state docs:
- CLAUDE.md: project purpose, reading order, roadmap section, and
standard-template notes now describe the built pipeline plus the
parts still open (full layout JSON schema, other per-controller
blocks, timing defaults, --skip-json).
- README.md: bin/ tree and usage examples for tro_extract/scl_skeleton.
- doc/Python_Scripts.md: intro counts (8 modules / 5 CLI tools),
header date, pipeline diagram, and tro_overrides.py in the lib list.

Add a Roadmap section to README.md and CLAUDE.md describing the two
still-to-be-written lib/ tools (tro_export.py, scl_gen.py) that will
turn the annotated CAD drawing into a JSON layout model and then into
TIA-Portal-importable SCL, including the --skip-json shortcut.
