Data workspace: slug edits silently discarded, with a React render loop in the console

[fosferon]

What happens

Editing a row's Slug in the Data workspace grid's detail panel appears to succeed — the input accepts the new value and the panel shows it — but the change is never persisted. Reloading shows the old slug, and the database row is unchanged.

At the same time the console fills with:

Maximum update depth exceeded. This can happen when a component calls setState
inside useEffect, but useEffect either doesn't have a dependency array, or one
of the dependencies changes on every render.

The two may or may not share a cause, but they occur together on the same interaction.

Steps

1. Open Data → Pages (any system table with a slug field should do).
2. Click a row to open the detail panel.
3. Change the Slug field, blur or tab out.
4. Reload — the old slug is back.

Expected

Either the edit persists, or it fails loudly with a visible error.

Workaround

PATCH /admin/api/cms/data/rows/{id} with the full cells object works correctly and persists. The change also survived a subsequent republish without the CRDT reverting it, so the underlying write path is sound — this looks specific to the grid's detail-panel editor.

Environment

• Instatic at 949ddb2d (v0.0.17 dev), SQLite, bun run dev
• Encountered on a pages table of 31 rows following a Site Import

Note

Found while migrating a real site onto Instatic. Happy to gather more detail or attempt a fix if you can point me at the intended commit path for that editor.
