Flow drops from five steps to three: role + use_case merge into a
single About-you screen (one Skip covers both; Continue stamps skip
markers on whichever group was left unanswered), and the source
question leaves onboarding entirely.
Source is now collected only by the workspace source-backfill prompt,
which additionally waits until agents/squads have completed at least
SOURCE_BACKFILL_MIN_AGENT_DONE_ISSUES (3) issues in the workspace —
attribution is asked after Multica has visibly delivered value, not
before. The count rides a limit:1 issues query keyed under
issueKeys.all so realtime invalidations keep it fresh, enabled only
for users who still owe an answer.
Server: questionnaire complete() narrows to role + use_case so the
funnel step doesn't stall on the now-deferred source; a new
metrics-only onboarding_source_submitted event (+ Prometheus counter)
tracks the backfill prompt's answer/decline transition once per user.
