From 07fe92bd98e368d4237eae04d6e8698daf61f8c3 Mon Sep 17 00:00:00 2001 From: Lakshman Patel Date: Tue, 15 Sep 2026 14:41:28 +0530 Subject: [PATCH 1/2] refactor(agents): extract built-in persona catalog to a data table BuiltinPersonas and CavecrewPersonas now iterate a package-level catalog and stamp timestamps per call, cloning slice fields so callers cannot mutate the shared data.
