Under the hood
Database read results now include an outside_writer flag alongside the existing foreign flag
What
When Claude Code reads from an artifact's shared database using the read_db action, the result now includes a new outside_writer true/false field, computed from a new check, in addition to the existing foreign flag that already detects when a document was authored by someone else.
Why
This gives Claude more specific information about database records, letting it tell apart documents genuinely owned and written by the current account from ones that also had a writer from outside, on top of the existing general foreign-document detection.
