+# Truthmark 2.2.2
+
+Previous version: 2.2.1
+New version: 2.2.2
+
+## Rationale
+
+Release a patch update for generated workflow-surface packaging and stale generated documentation cleanup.
+
+## Release payload
+
+- Preserve host-native skill packages with colocated support files and helper metadata so supported agent hosts can package skills without depending on a separate repo-local workflow copy.
+- Keep prompt, command, and top-level instruction surfaces compact while leaving skill-directory resources colocated with `SKILL.md`.
+- Remove unused repo-local workflow copies and implemented planning artifacts from the release surface.
+- Add generated-surface freshness diagnostics for host-native package entry/support files.
+- Refresh package metadata and generated runtime markers for Truthmark 2.2.2.
+
