Greptile Summary

Fixes a routing bug where an explicit host=node per-call override was silently dropped when tools.exec.host=auto and elevated exec defaults were active. The elevated path previously early-returned using only configuredTarget (bypassing requestedTarget and validation); the fix runs validation first, merges requestedTarget ?? configuredTarget into selectedTarget, and applies the elevation guard to that merged value. A mismatched target under elevated+node now throws instead of silently routing to node.

Confidence Score: 5/5

Safe to merge — targeted fix with no correctness issues found and good regression coverage.

All changes are correct and well-tested. No P0/P1 issues found. The logic is sound: validation now runs before elevation, selectedTarget correctly incorporates the per-call requestedTarget override, and downstream callers of effectiveHost/selectedTarget are unaffected by the change in returned values.

No files require special attention.
