Root cause:
dist/index.js line ~2251 uses a raw DOM-event handler for the custom Select primitive:

javascript
// BROKEN — Select component passes raw value string, not an event
onChange: function (e) { setWorkspaceKind(e.target.value); },


The codebase already has a safe wrapper pattern elsewhere:

javascript
// CORRECT — handles both raw-value and event-object dispatch
onChange: function (e) {
    const v = e && e.target ? e.target.value : e;
    setter(v == null ? "" : v);
}


The inline create form was compiled without that guard.

Backend is fine: CLI hermes kanban create --workspace worktree and --workspace dir:/path work correctly, as does the kanban_create tool. This is purely a compiled-dashboard frontend bug.

Patch (verified on local install):
javascript
// dist/index.js, InlineCreate component workspace Select
onChange: function(e){const v=e&&e.target?e.target.value:e;setWorkspaceKind(v==null?"":v);},


Suggested fix: Rebuild the dashboard bundle from source, ensuring the inline create workspace select uses the same safe event normalizer as the rest of the component tree.
