Each block lists what we actually changed in the room. Outcomes stay modest because maintainers still say no sometimes.
University partner
Gangnam bootcamp merge clinic
Challenge: Students froze when CI failed on week two.
Approach: We layered Patch Packaging Week exercises before live reviews.
What shifted: Median time-to-first-review shortened without promising upstream merges.
Community guild
Singapore remote guild
Challenge: Volunteers ghosted async threads after facilitator churn.
Approach: Sprint Review for Volunteers agendas plus rotating note takers.
What shifted: Attendance stabilized; we still disclose that volunteer hours vary.
Hardware startup
Busan hardware shop floor
Challenge: Internal forks diverged from upstream documentation.
Approach: Release Notes Radar plus changelog literacy drills for eight engineers.
What shifted: Teams produced shorter risk briefs before each vendor drop.
Public sector pilot
Seoul civic OSS pilot
Challenge: Issue intake was polite but vague, slowing triage.

Undergraduate club
Student club desk bundle
Challenge: Leaders needed facilitator scripts without sounding corporate.
Approach: Maintainer Tone Clinic excerpts plus lightweight voice note practice.
What shifted: Club retained mentors; we did not staff their events directly.
