… exercises The class shared Airflow VM runs Airflow 3. The Streamlit exercises used the Airflow 2 pattern (/api/v1 + order_by=-execution_date), which 404s against the v3 API. Corrected ex3/ex4 starters and solutions to /api/v2 and -logical_date, matching the Week 12 chapters. Also removed em dashes from the exercise files (project style: colons/commas, never em dashes).

…Auth) Live smoke-test of the shared Airflow 3.2 VM: auth=(user,pass) returns 401 on /api/v2; the API needs a JWT from POST /auth/token sent as a Bearer header. Added a cached get_airflow_token() helper to ex3/ex4 (starter + solution) and switched every dagRuns call to Authorization: Bearer. Updated the ex3 starter TODO to describe the token flow.

…irflow-free) Move the dashboarding week from week-12 to week-11 to staff each week to a teacher's strength (the Airflow expert is only available in week 12). - Rename data-track/week-12 -> data-track/week-11 (history preserved). - README: drop the Airflow DAG prerequisite, add PG_URL, TODO on Notion link. - Streamlit ex3: rewrite from "last DAG run" panel to KPI tiles from fct_trips. - Streamlit ex4: rewrite from Airflow panel to daily trip-volume chart + existing Postgres freshness panel. - Strip Airflow env vars and the requests dependency; add pandas for ex4. - Metabase ex1/ex2 unchanged (already dbt/Postgres only). Out of scope: authoring the new week-12 Airflow exercises and editing the Notion chapter prose/slug. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…epos From week 11+ the Data Track uses external reference repos with exercise branches instead of one-off exercise folders in Learning-Resources (mirrors the Week 10 dbt reference repo). Replace the week-11 exercise_N folders with a pointer README linking to: - lassebenni/nyc-taxi-streamlit-reference (KPI tiles, daily-trend chart) - lassebenni/nyc-taxi-metabase-reference (SQL Question, dashboard + filter) Both read the Week 10 fct_trips dbt mart from Postgres — no Airflow.
