Field notes without stock hero photos

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.

Approach: Issue Triage Field Notes with anonymized civic threads.

What shifted: Duplicate issue rate fell; privacy review stayed external to us.

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.
