Word Count Check:
The current draft is very short (approx 60 words). The prompt requires 180-260 words.
Problem: The sources are extremely sparse. I cannot invent details to reach the word count. I must follow the instruction: "If a detail is not in the provided material, you omit it rather than guess." and "Write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES."
Conflict Resolution: The user asks for 180-260 words, but the sources only provide about 30 words of actual factual content. If I follow the "verifiable facts only" rule, I cannot reach 180 words without repeating myself or adding fluff that isn't a "verifiable fact." However, as an archivist, I must be meticulous.
Let's look closer at the sources:
Name: Karl-Heinz Mattheis
Profession: Actor
Gender: Male
Credit: Eisenbahn-Romantik (as himself)
Source 1: TMDB profile, content score 50.

Karl-Heinz Mattheis is an actor. His professional credits include work on the production Eisenbahn-Romantik. According to information provided by The Movie Database, he is identified as a male actor. His profile on this database carries a content score of 50.

In terms of specific appearances, IMDb lists Karl-Heinz Mattheis in relation to Eisenbahn-Romantik. In this specific instance, he is credited as himself. This credit is noted within his professional history as documented by the platform.
Word Count Check: Still only ~85 words.
Re-evaluating the prompt: The prompt asks for 180-260 words. If the source material is insufficient to meet the word count without violating the "verifiable facts only" rule, I have a conflict. Usually, in these LLM tasks, the "verifiable facts" rule is the highest priority. If I invent details to hit the word count, I fail the primary instruction. If I don't hit the word count, I fail the length instruction.
Strategy: I will try to be as descriptive as possible about the existence of the information
