Problem

The system-model Writer emits a journey view even when the journey has no steps. A one-object script such as dup-sweep or dead-code-sweep produces an empty dynamic view. The viewer shows a blank diagram.

Reproduce

n/a: found while recording os-sdlc journeys (step 7); standalone scripts give no steps.

Approach

Required work:

Make the Writer skip, or fail loudly on, a journey with no steps — check: present steps in plugins/os-sdlc/lib/os_sdlc/system_model/writer/journey_file.rb

Acceptance criteria

Given a journey with no steps, when the Writer runs, then it writes no view file and reports the journey by name.
Given a journey with steps, when the Writer runs, then it writes the view as before.

Origin

Trigger: system-model steps 7 and 8 (os-sdlc journeys, commit 8c28fd4f; course check in docs/system-design-format/README.md section 6)
Improvised this session: none
Chain: blank diagram for standalone scripts ← Writer renders every journey without checking its steps ← DESIGN (plugins/os-sdlc/lib/os_sdlc/system_model/writer/journey_file.rb)
Root candidate: none found; searched journey, journey_file, Writer, pattern-landscape
Where: plugins/os-sdlc/lib/os_sdlc/system_model/writer/journey_file.rb
