 - **Gap 4 in miniature:** fresh-host store is empty; nothing defines what seeds it.
 - **Lease posture:** hand-rolled seats launch bare `claude` → ungated by construction
   until `mosaic fleet launch` exists (consistent with current bare-for-real-work rule).

+Diffed operator vetted ungated settings vs shipped gated template: the delta is exactly
+three items — template-only PreToolUse mutator-gate entry, template-only Stop
+receipt-observer entry, operator-only mcpServers.sequential-thinking block (whose omission
