+- Created 3 Go task directories: navprove-teleport-ssh-001, navprove-vuls-oval-001, navprove-flipt-cache-001
+- Each has 6 files: task.toml, instruction.md, environment/Dockerfile, tests/test.sh, tests/reference_fix.patch, tests/find_and_prove_verifier.sh
+- task.toml: name, difficulty=hard, time_limit_sec=1800, language=go
+- test.sh: Go-specific TEST_COMMAND='go test -run TestRegression -v -timeout 60s', AGENT_TEST_PATH=/workspace/regression_test.go
+- Files changed: 18 new files (6 per task × 3 tasks)
+- **Learnings for future iterations:**
+  - Go tasks differ from Python only in: language field, AGENT_TEST_PATH extension (.go vs .py), TEST_COMMAND (go test vs python3 -m pytest)
+  - Go test -timeout flag uses Go duration format (60s) not seconds integer
