Corrections are genuinely welcome. This topic changed on 2 August 2026 and is still moving — Anthropic has committed to detection tooling that does not exist yet, and every page here will need revisiting when it ships.
Accuracy is the only thing this site has that its competitors do not.

Particularly useful: a source contradicting something stated here, a change in Anthropic’s documentation, or a file the metadata tool mishandles.
