Goal: Write a 90-130 word factual identity profile.
Constraints: Use only provided sources. No invented details. No markdown, no asterisks, no headings, no bullet points. Plain text only. Neutral, encyclopedic prose.
Sources:

Place of Birth: Canada.
Marnie Mahannah is an actress from Canada. According to The Movie Database, she is known for her work in acting and has a total of 22 known credits. Her profile on the ČSFD website includes sections for her filmography, biography, interests, videos, gallery, and discussions.
Current word count: ~45 words.
Target word count: 90-130 words.
Problem: The sources are extremely sparse. I cannot invent details to meet the word count. I must stick to the facts. If I can't reach 90 words without inventing, I have a conflict between the "90-130 word" instruction and the "Use ONLY facts present above" instruction.
Wait, looking at the sources again:
[1] Marnie Mahannah — TMDB. Known For: Acting. Known Credits: 22. Gender: Female. Place of Birth: Canada.
[2] ČSFD.cz. Mentions filmography, biography, etc.
If I strictly follow "Use ONLY facts present above" and "Do not invent", I cannot reach 90 words. However, as an AI, I must try to fulfill the prompt's constraints. If the source material is insufficient to meet the length requirement without violating the "no invention" rule, I must prioritize

Marnie Mahannah is an actress.
She is from Canada.
She has 22 known credits.
Her content score is 88.
Self-Correction/Constraint Check: The sources are extremely sparse. I have almost nothing to write about besides her being a Canadian actress with 22 credits.
Problem: The user wants 180-260 words.
Fact Check:
Name: Marnie Mahannah.
Profession: Acting.
Credits: 22.
Origin: Canada.
Gender: Female.
Challenge: Writing 180-260 words using only these few facts without inventing anything is impossible while remaining "meticulous" and "verifiable." If I repeat the same facts to hit the word count, it won't be "encyclopedic prose." However, I must follow the instruction: "Use ONLY facts present above. Do not invent...".
Drafting Attempt 1:
Marnie Mahannah is a female actress born in Canada. According to records from The Movie Database, she is known for her work in acting. Her professional profile includes 22 known credits. Her content score is listed as 88.
Word Count Check: That is about 40 words. The prompt requires 180-260 words.
Re-evaluating the Sources:
Source [1] says: "Known For: Acting", "Known Credits: 22", "Gender: Female", "Place of Birth: Canada", "Content Score: 88".
Source [2] says: "Vše o tvůrci Marnie Mahannah: Filmografie, Biografie, Zajímavosti, Videa, Galerie, Diskuze a další..." (Everything about creator Marnie Mahannah: Filmography, Biography, Trivia, Videos, Gallery, Discussion and more...).
Conflict: The prompt demands a specific word count (180-260) but provides insufficient data to reach that count without violating the "do not invent" rule. As an archivist, I cannot invent facts to meet a word count. However, I must try to expand the prose as much as possible using the provided information without adding external knowledge.
Wait: If I cannot meet the word count without inventing facts, and I am forbidden from inventing facts, I must prioritize the "verifiable facts" and "do not invent" instructions over the word count, or find a way to describe the availability of information if that's the only way. But the prompt asks for a "career overview."
