 lists projects with a
 health score (0–100); each project page shows its routines sorted most-urgent
 first (À jour / À faire / En retard / Très en retard) with one-tap "Fait"
-completion. A search box above the list filters it live — type `Cuisine/` to
+completion. Next to each routine's frequency, the age of the last completion
+replaces its date — "fait hier", "fait il y a 5 jours" — and once the
+deadline has passed the stamp switches to the lateness ("3 jours de

 see every `Cuisine/…` routine — matching case- and accent-insensitively.
 Editing a routine creates a new immutable version, and every completion
 records the exact version it was made against, so the past is never rewritten.
