本批改变了共同目标根节点

Error message

本批改变了共同目标根节点

What it means

mergeBatch enforces a single shared root node (parent===null). If state already has a root and the merged node set's root differs from it, the whole batch is rejected. This prevents the model from replacing the conversation's common goal root mid-job.

Solutions

1. Keep the original root node with parent:null unchanged in every batch
2. Nest all changes under the existing root instead of creating a new one
3. If a new goal is truly needed, restart organizeLong rather than mutating the root mid-run
4. Instruct the model that the root id is immutable

Example fix

// before
{ id: 'new-goal', parent: null }
// after
{ id: 'existing-root-id', parent: null, summary: updatedSummary }

if (oldRoot && upserts.some(n => n.parent === null && n.id !== oldRoot.id)) throw new Error('root change attempted');

try { mergeBatch(...) } catch (e) { if (e.message === '本批改变了共同目标根节点') { rejectRootChange(); } else throw e; }

When it happens

Trigger: An upsert changes the existing root's parent, or a new node with parent:null is introduced while an old root exists (e.g. old root re-parented under a new node).

Common situations: Model tries to 're-organize' around a new goal node; resume flow where the model rewrites the hierarchy from scratch.

Understand the failure class

Background: "Invalid state transition" errors: "status must be X, actually Y", "already rejected/charging/uninstalled", "cannot ... while running" — what they mean when a library rejects your call — this error's family across 31 libraries.
