 ## Accumulated Context
 
@@ -151,6 +152,8 @@ Recent decisions affecting current work:
 - [Phase 05-employee-design]: AgentTemplate is global (not tenant-scoped) — templates readable by all authenticated users, no RLS; deploy creates independent Agent snapshot
 - [Phase 05-employee-design]: build_system_prompt() always appends AI transparency clause — non-negotiable per Phase 1 architectural decision
 - [Phase 05-employee-design]: Template GET endpoints use get_portal_caller (not require_tenant_member) — no tenant_id path param in global template routes
+- [Phase 05-employee-design]: Wizard state held in React useState — persona text in URL would be impractical; step position exposed via URL searchParam only
+- [Phase 05-employee-design]: Channels step is informational in v1 — agent routing is tenant-scoped, not per-agent; no channel-agent join table in v1
