Validate / build-and-test (push) Successful in 30s
Validate / build-and-test (push) Successful in 30s
- Implement Safety Manager (SWA-001, ASIL-D): Hill-Hold + Auto-Apply state machine, 13 unit tests - Update SWA-002 + SWA-001 link coverage so all SWE reqs are covered - New tool: tools/traceability.py — Markdown-frontmatter-basierter Traceability-Checker + HTML/JSON-Matrix-Generator (Doorstop-Format ohne Doorstop-Dependency) - New tool: tools/render_plantuml.py — extrahiert PlantUML-Bloecke aus arch/**.md und rendert via plantuml.com zu SVG - validate.yml: neue Steps Traceability-Check, Matrix-Publish, PlantUML- Render; uploaded als Gitea-Artefakte

"""

Traceability-Werkzeug fuer demo-epb.
|
||||
|
||||
Liest alle Markdown-Items in reqs/ und arch/ ein, validiert Links bidirektional
|
||||
und erzeugt eine HTML-Traceability-Matrix.
|
||||
|
||||
Doorstop-kompatibles Format (YAML-Frontmatter + Markdown-Body), aber ohne
|
||||
Doorstop-Dependency — bleibt portabel.
|
||||
|
||||
Subcommands:
|
||||
check Validiert Konsistenz, exit 1 bei Fehlern
|
||||
publish DIR Schreibt HTML + JSON nach DIR/
|
||||
|
||||
Run:
|
||||
python3 tools/traceability.py check
