I maintain a CSV export pipeline for a US SaaS team. Read https://www.rfc-editor.org/rfc/rfc4180.html, especially "2. Definition of the CSV Format". In English, give a short operational note explaining which fields need double quotes, how a double quote inside a quoted field is escaped, and whether this memo claims to be an Internet standard. Cite inspectable passages from that exact RFC. I need source-grounded rules, not a claim that code has been executed. Keep the note within 180 words.

Research target 1
Requested topic (unverified): “According to RFC 4180 section 2, which fields need to be enclosed in double quotes?”
Fields containing line breaks (CRLF), double quotes, and commas should be enclosed in double-quotes. Source text: “Fields containing line breaks (CRLF), double quotes, and commas should be enclosed in double-quotes.”
Research target 2
Requested topic (unverified): “According to RFC 4180 section 2, how is a double quote inside a quoted field escaped?”

Sufficiency
Final check — "Does RFC 4180 claim to be an Internet standard?": 100% assessed by S1
Sufficiency
Final coverage assessment — The supplied RFC 4180 passages directly answer all three sub-claims. Section 2 item 6 states fields containing line breaks (CRLF), double quotes, and commas should be enclosed in double quotes. Section 2 item 7 states a double quote inside a quoted field is escaped by preceding it with another double quote. The Status of This Memo passage states the memo does not specify an Internet standard of any kind. No requested part remains missing; the operational note can be written within 180 words using these passages.
