+# Norman Arauz
+
+## Role
+
+Frequent Fidelity/XFlow engineer collaborator in historical Slack threads.
+
+---
+
+## Known Context
+
+- Repeated day-to-day implementer/investigator across XFlow SwiftUI, AO/Fid4 bugs, version bumps, analytics, and pipeline debugging
+- Often coordinated with Jeff on scope, descriptions, approvals, and manager-ready wording
+- Frequently investigated consumer-reported issues directly in Fid4 and sample-app parity checks
+- Often produced detailed technical findings first, then asked Jeff to polish or approve external wording
+- Exact formal role may need confirmation if used outside workspace memory
+
+---
+
+## Guidance
+
+- Treat Norman as a strong source for historical implementation detail, reproduction findings, and release-process context
+- If later communication clarifies the formal team/title, update this file directly
