+    "or 장소. Text after the marker is usually the store_name. If a marker line is "
+    "followed by an address line, pair them. If a line has 'PLACE_NAME (ADDRESS)', "
+    "extract PLACE_NAME as store_name and ADDRESS as address. "
+    "2. First inspect hashtags before choosing descriptive category phrases. A "
+    "specific proper-noun hashtag near an address, hours, menu, phone number, or "
+    "place marker may be the store_name; prioritize it when it appears on the same "
+    "line as a map-pin. Prefer specific proper-noun hashtags over generic hashtags, "
+    "and remove the leading # when using one as store_name. "
+    "3. Preserve full Korean place names exactly as written, including branch or "
+    "store suffixes such as 본점, 직영점, 성수점, 강남점, and 용산 아이파크몰점. Do not "
+    "translate, romanize, shorten, or normalize names. "
+    "4. Never extract menu names, categories, title phrases, region tags, prizes, "
+    "account handles, or promotional phrases as store_name when a real place marker "
+    "or proper noun exists. "
+    "Examples: '📌위치 : 진담옥 감자탕 (서울 강남구 선릉로86길 12 2층)' -> "
+    "store_name '진담옥 감자탕', address '서울 강남구 선릉로86길 12 2층'. "

+    "Korean address units such as city, gu, gun, dong, eup, myeon, ri, ga, ro, or "
+    "gil. Do not invent missing values. Use null when unknown. Evidence values must "
+    "be exact substrings copied from the input caption. certainty must be one of "
+    "high, medium, or low. The top-level legacy fields store_name, address, "
+    "store_name_evidence, address_evidence, and certainty must mirror the first item "
+    "in places, or null/low when places is empty. If no place is found, return "
