Why: Dev-level pin consistency (scripts/check-pins.sh hard-errors on nested vs Dev-level drift); agent-native main advanced to 37c5e6f (Request OutputFormat/Tools, agent-native #40). Evidence: adapters/native and root suites green against 37c5e6f (SELF); CI authoritative (GATE). Impact: nested deps/agent-native 1ac21c6 -> 37c5e6f; no squad source changes.
