Jan-Peter von Hunnius 193562cbc4 openup: doc restructure - template alignment + design sequences (non-PSP)
Align the OpenUP markdown set to the blank templates (process-data repo,
templates/openup/) per BUILD-CHECKLIST 7. Scenario step text unchanged;
the EA model needs no change (brief descriptions already live in the
model's UC/actor notes).

- vision.md: positioning tables, stakeholder summary, user environment,
  needs-and-features table (R1/R2), other product requirements
- use-case-model.md: per-UC specification sections (brief description,
  actor descriptions, named alternative/exception subsections with
  numbered steps, post-conditions, special requirements)
- supplementary-specifications.md: category tables with priority and
  use-case columns + reverse coverage matrix; IDs unchanged
- test/quality-check-procedure.md: migrated from Joplin (single content
  home); stale open items marked resolved (WI-1/WI-2)
- analysis-design/sequences/: 12 PlantUML design sequences (lifelines =
  analysis classes, messages = design elements; per the PlantUML layout
  style guide) + PNG renders; embedded in Architecture Notebook 9.3
- Joplin consolidated: project content notes deleted (all live in
  docs/game + docs/openup); Joplin keeps the status note only

title UC-10 Practice Bard Song (design sequence)
actor Player
participant "SongBoundary\n«/api/characters/{id}/songs»" as boundary <<boundary>>
participant "SongService\nsb-api::routes::set_song" as control <<control>>
participant "BardSong\nBARD_SONGS + active_song" as entity <<entity>>
== View ==
Player -> boundary : GET songs
boundary -> entity : available_songs (level-gated)
boundary --> Player : songs + effects + active song
== Set / Clear ==
Player -> boundary : POST song id (or empty to clear)
boundary -> control : set_song(character, song)
alt non-Bard
control --> boundary : 403
else unknown song
control --> boundary : 404
else level too low
control --> boundary : 422
else ok
control -> entity : active_song = song (or None), persist
control --> boundary : {success, message, active_song}
boundary --> Player : {success, message, active_song}
end
note over entity : active song applies in UC-08 combat (step 5)
