mesh/repo-check pass: its merge-check.sh passed, each part in its toolchain: merge-check.sh (typescript), replays/merge-check.sh (go), asks/merge-check.sh …
Proved with go run ./cmd/prove R237: fails on mesh-controller #253's commit
before (72edb45), passes on the fix (5facd8b, mesh-controller #253).
TestReplay237 needs MESH_TEST_POSTGRES (inventory.ForTest raises a throwaway
database), same as the controller's other store-backed replays.
