Description
During the 2026-02-26-2047 onboarding-analysis test run, Step 1.5 archetype inline Python hit a pandas index alignment error (index intersection of differently-sized Series after merge). Fixed inline during the run by resetting cohort index and using boolean masks. If archetype analysis gets formalized into a script, apply the same fix there. Low priority — only surfaces when running Step 1.5 manually.
