The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Happened as dated, per the source: "completed earlier in 2024 and took around two years".
Port of Melbourne's own project overview page is the authoritative primary source for the Swanson Dock rail overhaul, consistent with the pin's claim, though the domain could not be verified for direct fetch and no publish date is stored for it.
Vinci's own press release, titled "Melbourne Port Rail Transformation Project completed" and carrying a stored publish date of 1 February 2024, exactly matches the pin's stored completion date, though the domain could not be verified for direct fetch to quote the text.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
