+## [2.9.0] - 2026-08-17
+
+### Added
+
+- Opening Public post from the landed Demo Corp members now names the
+  next action after landed cited evidence: Linked post evidence is
+  current, then read Event Lineage on that post. Home list opens do
+  not add that copy. No TEPP theta is invented. No cutoff body is
+  invented (ADR 0016).
