 ### Changes
 
+- Diagnostics/OTEL: emit bounded exec-process diagnostics and export them as `openclaw.exec` spans without exposing command text, working directories, or container identifiers. (#70424) Thanks @jlapenna.
 - Diagnostics/OTEL: support `OPENCLAW_OTEL_PRELOADED=1` so the plugin can reuse an already-registered OpenTelemetry SDK while keeping OpenClaw diagnostic listeners wired. (#70424) Thanks @jlapenna.
 - Control UI: refine the agent Tool Access panel with compact live-tool chips, collapsible tool groups, direct per-tool toggles, and clearer runtime/source provenance. (#71405) Thanks @BunsDev.
 - Memory-core/hybrid search: expose raw `vectorScore` and `textScore` alongside the combined `score` on hybrid memory search results, so callers can inspect vector-versus-text retrieval contribution before temporal decay or MMR reordering. Fixes #68166. (#68286) Thanks @ajfonthemove.
