+# Operator Preferences
+
+## Operator
+<!-- One paragraph: who the operator is. Leave for the operator to confirm; do not fabricate. -->
+
+## Fact / Pattern
+<!-- Promoted, deduped, timeless rules. No date prefix. Add only when a rule is stable. -->
+
+## Observations
+<!-- Timestamped raw observations. Default landing zone for new evidence: `- {{DATE}}: ...` -->

+## Recommendation or Implication
+
+## Review Notes
+Seeded empty at bootstrap ({{DATE}}). Raise confidence once preferences are confirmed through day-to-day use.
