+- **Configuration Lifecycle Tracing:** When modifying state, credentials, or

+  environment capture down to the target consumer option layer, ensuring

+  inference to specific entry points, ensuring absolute uniformity across
+  interactive CLI usage, background jobs, and programmatic SDK embeddings.
+- **Partner & Client Invariants:** Treat established integration profiles and
+  edge-case workarounds as stable contracts. Ensure new validation routes fall
+  back to or preserve legacy mapping where safe to prevent behavioral
+  regressions for active sidecars while allowing for critical security fixes.
