 # Shade V2.3 — Tillit, retention, integrasjon og observability
 
+**Status:** Done — superseded by V3.3 (trust UX), V3.4 (observability),
+V3.10 (recovery), V3.12 (KT). Alt levert i 4.0 GA — se
+[`docs/ROADMAP.md`](../ROADMAP.md).
+
 Dette dokumentet beskriver **høyere ambisjonsnivå** og **plattformkryssende** arbeid: brukertilfeller der tillit må være **eksplisitt**, data må **utkrympes**/ryddes automatisk, apper må **enkelt koble seg på** kjente transportmønstre, og drift må **observere** uten å lekke innhold.
