What
When a write would make a project bigger than its maximum size, the write is refused. The error used to be a sentence starting "Write refused: this write" with an estimate of how many tokens (the units the model counts text in) the write would add. It is now the code write_would_exceed_project_size_limit.
Why
The wording you see for this error may be different. If you search for it or match on it, use the new code.
