Trace a viral claim to its first source

Investigate [CLAIM] using [AVAILABLE LINKS OR CLIPPINGS]. Build a source trail from the most recent repost backward to the earliest accessible primary material. For every link, record publication date, what it actually states, whether it cites another source and whether the cited source can be opened. Return a chain diagram in text, a three-level verdict on support and a list of unresolved gaps. Do not treat ten sites repeating one claim as ten independent confirmations. If browsing is unavailable, provide the exact searches to run and label the result unverified.
