+# AITURK IDE beta.20 mobile adapter
+
+The mobile catalog now uses the official live Hermes catalog, its cache and
+removed-entry list. Parser and nine official offline seed entries are ported
+from NousResearch/hermes-agent ad12263a5ed43109d3942a8af04d4cef210fa6ae.
+Only PyYAML import compatibility differs in the parser. The existing installer
+checks out the catalog's exact commit; client URLs cannot override catalog names.
+Version/platform incompatibility is reported before installation.
+
+Mobile subagent roster/tail RPCs are connected to the existing live registry.
+Roster supports durable conversation lineage after reconnect, like upstream.
+Tail and interrupt retain exact live-session/transport authority. Transcript
+reads are bounded and confined to the profile's delegation log directory.
+The existing mobile fork fallback already uses session.branch only for -32601;
+it was not a missing feature and is unchanged.
+
+No new model, team, cron job, permission, or account is installed by these changes.
+The mobile Keys/Files/Vault/Connectors exclusions remain as before; this release
+does not claim those unsupported remote screens are implemented. Android beta.5
+can use the new endpoints without a new APK. Physical-phone acceptance is separate.
