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: "In 2021, the City of Sydney announced that the state government had approved its planning framework that would allow buildings of up to 310m."
ABC News Australia confirms "In 2021, the City of Sydney received state government approval for a planning framework that would permit buildings reaching up to 310 metres," matching the pin's stored 2021 date and claim exactly.
The City of Sydney's own release describes specific site approvals up to 310-319m, but is itself dated 3 July 2025, about four years after the pin's stored 2021 date, so while it corroborates the broader trend of raised height caps, it does not itself confirm the original 2021 framework approval.[1]
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.
