The hub shows that it is alive and who keeps it alive, and the track map comes first. Five commits. The first two were pushed to #69 after it was merged, so they come along here.

Carried over from #69

• Track map:
  • numbered lines and the line picker above the map
  • a one-row reading guide
  • cleared quests shown on the map, with a "지금 여기" pin
  • transfer numbers on the phone strips
• One record:
  • stage stamps live in the passport
  • Level 3 and Level 4 quests are things to do (comment, first PR, runner, Builder)
  • the goal chips give way to one start-finder button

Track map first, Level 0–4, less to read

• The curriculum opens on the track map.
  • Phones now get the map itself, panned sideways, instead of the long line-by-line list.
  • That list is folded under it as "노선별 목록으로 보기".
  • On phones the line picker is one swipeable row.
• Levels read as Level 0 … Level 4: roadmap nodes, the level panel, map zones, route stops, the dialog, the finish card and the hero buttons. Ids stay L0–L4 in data and links.
• The roadmap copy is shorter:
  • one sentence under the tabs
  • no "STAGE n" kicker
  • no tags on the cards
  • the goal reads "다 하면 여권 스탬프 · n / total"

Alive: activity, credited by name

• Under the hero: "지금 팀에서" shows the latest team activity on GitHub, one item at a time.
  • Each item is a person, a repo and what they did, with how long ago.
  • It changes every 5 seconds and pauses on hover or focus. It does not rotate with reduced motion.
  • "더 보기" jumps to the feed.
• In the contributors section: "최근 30일, 이렇게 기여했어요".
  • Everyone who contributed in the last 30 days, then the last 8 contributions.
  • Builders link to their Builder page, everyone else to their GitHub profile.
  • The block ends with a button to find a first issue.
  • Stars and forks are counted on their own line, not as contributions.
• What counts:
  • pushes to the default branch
  • PRs opened and merged
  • issues opened, comments and reviews
  • releases and new repos
  • Bots are left out, and repeated pushes to the same repo collapse into one line.
• Where it comes from:
  • The hub asks api.github.com/orgs/CausalInferenceLab/events when a visitor opens the page.
  • If that is refused (rate limit), it uses data/activity.json.
  • scripts/build_activity.py builds that file on every deploy and now also daily. It fills in PR titles, which the events API leaves out.
  • The weekly stats refresh still runs only on Mondays.

The loop, visible

"참여하기" opens with four steps, each linking to its section:

1. 배우기: 자료 17개
2. 기여하기: contributors in the last 30 days
3. 이름이 올라가기: Builders, runners
4. 공유하기: Builder page, finish card

A dashed line under them says the shared link brings the next person back to step 1. The step cards below lose their big numbers so the two numberings don't clash.

Events

• section_view (section): curriculum, contrib, activity, events, posts, join. Sent once per page view when about a third of the section is on screen.
• live_click (placement: ticker | feed, target: builder | github | repo | feed, kind, repo)
• loop_click (step)
• click_event (action: signup | record | next_strip, event_order, placement) for the events section and the next-event strip.
• The join-section handler no longer counts loop links as click_join.

Checked

• A scripted session with HUB_DEBUG fires each new event once, with the expected params.
• axe (wcag2a/aa) found no violations on desktop and phone, light and dark, with the feed filled.
• The existing regression scripts pass. They were updated for the map-first tab.
