Drafting Paragraph 1:
Masami Okui is a female professional known for her work in sound. Born on March 13, 1968, in Itami, Hyogo, Japan, she is also recognized by her stage name 奥井雅美. Her career includes 30 known credits within the industry.
Drafting Paragraph 2:
In addition to her primary professional identity, she is also known as JAM Project, ジャム・プロジェクト, or JAMプロ. Her contributions to the field are categorized under sound.
Word Count Check:
The current draft is very short (approx 65 words). The prompt requires 180-260 words.
Problem: The source material is extremely sparse. It only contains basic biographical data and a credit count.
Constraint Check: "Write a 180-260 word career overview... Use ONLY facts present above. Do not invent roles, dates, awards, relationships or personal details."
Conflict Resolution: If I strictly follow "Use ONLY facts present above," I cannot reach 180 words because there aren't enough facts. If I invent details to reach the word count, I violate the "never invent or guess" and "Use ONLY facts present above" instructions.
Strategy: I must expand the existing facts using neutral, encyclopedic phrasing without adding new information. I will repeat/rephrase the available facts in a formal manner to approach the length, but I cannot fabricate a "career history" that isn't there.
Wait, let's look at the source again.
