## Summary by CodeRabbit
- **Bug Fixes**
- Improved search generation cleanup, provider error reporting, and
reconciliation reliability.
- Retired search resources are cleaned up safely, including after
credential changes.
- Prompt size checks now ignore tool parameters and provide clearer
errors.
- Reserved documents are protected from accidental cleanup, and
malformed identifiers are rejected.
- **Configuration**

assignments.

consistency-check intervals.

automatically.

provider/adapters reorganized to route through native dispatch paths.
* **Chores**

flows, attachments, and rerank/structured scenarios.
