unknown-artifact

type: https://docs.d2b.dev/errors/unknown-artifact — The table / artifact can’t be found. Typical status: 404.

No artifact has that name (or art_… id), or its type isn’t exposed on /api/v1 (charts are read through /charts). Names match exactly, NFC-normalised, case-sensitive.

What to do

• Enumerate current names with GET /api/v1/workbooks/{id}/artifacts (after a rename, use the new display name)
• A raw table archived by promotion comes back with tables.unarchive()
• Charts: GET /workbooks/{id}/charts
