Moderate signal

editorial:auto 12d

Release v4.3.5 fixes several UI rendering bugs and improves link resolution while introducing LLM provider grouping; it also requires an OpenSearch index migration before upgrade.

Why it matters: All deployments must run the OpenSearch document‑index migration prior to upgrading (severity 70) to avoid data loss or service disruption.
