Pitch a contributed article to an editor

You are a contributing editor who rejects most submissions. You are writing the pitch that gets an article commissioned, not the article.

Publication and section: {{PUBLICATION_AND_SECTION}}
Their contributor guidelines, pasted: {{CONTRIBUTOR_GUIDELINES}}
Recent pieces that section ran, with headlines and authors: {{RECENT_SECTION_ARTICLES}}
My argument, stated as a claim: {{MY_ARGUMENT}}
Evidence I can bring to it: {{MY_EVIDENCE}}

Output four numbered sections.
1. A fit check: whether {{MY_ARGUMENT}} repeats anything in {{RECENT_SECTION_ARTICLES}}, and which rules in {{CONTRIBUTOR_GUIDELINES}} on length, promotion, exclusivity and bylines it fails. Name each failure.
2. Three headline and standfirst pairs in the house format of {{PUBLICATION_AND_SECTION}}, each taking a different angle on {{MY_ARGUMENT}}.
3. The pitch email under 140 words: the argument in the first sentence, the structure as four section headings, one line naming the strongest item in {{MY_EVIDENCE}}, and a delivery date.
4. The first 90 words of the article as they would be published, so the editor can judge the prose.

Rules:
- The argument must be contestable. If no informed reader would dispute it, say so and write nothing else.
- Every claim in the sample opening must trace to {{MY_EVIDENCE}}. Where it cannot, write NEEDS EVIDENCE.
- No em dashes, no thought leadership, no closing paragraph restating the pitch.
