 2026-09-30 | "For my lab website. Let's add to the ### Former Graduate Students. Mich Pillet \"Michiel (Mich) Pillet ...\" who is listed on the website did his PhD in my lab. He should be added to the ### Former Graduate Students." — Added Michiel (Mich) Pillet to the sync-safe alumni overrides with a 2017 lab start year based on his public profile, existing profile links and affiliation, and a PhD label without an unverified completion year.

+    Outcome: Added an exact-name mapping in _data/alumni_photos.yml to /assets/img/team/michiel_mich_pillet.jpg, reusing the existing staff portrait without modifying the image, staff profile, biography, or degree information. The unrelated _pages/news.md changes were left untouched.
+    Validation: YAML uniqueness and image-existence assertions, scoped Prettier check, editor diagnostics, and actual graduate-card Liquid rendering passed. The first rendering harness lacked Jekyll's filter-cache context and failed; supplying that context resolved the test failure. Full local notebook build was not rerun. Publication of the photo remains pending at this entry.
