import "testing"

// Top-level Test* entry points. Each delegates to a runX function in the
// matching <name>_test.go file. Names are number-free (TestX) so isolated
// runs via `go test -run TestKeyPairs` are stable.
//
// Every run* function self-bootstraps prerequisites via harness.Discover* /
// harness.Ensure* (or the package-local need* / iamEnsure* helpers), so a
// targeted `go test -run TestX` invocation works in isolation without
// relying on a sibling Test* having stashed state.
//
// Parallelism (mulga-siv-128):
//
// Bucket #1 (parallel): read-only or own-everything Tests below call
// t.Parallel(). They share the package fixture but never mutate the
// singleton EC2 instance, default VPC, or default SG.
//
// Sequential (no t.Parallel — would race the singleton VM or shared state):
//   - TestClusterStatsCLI                 : asserts baseline cluster state
//     (0/ CPU, "No VMs found"); must run before any launches.
//   - TestInstanceLaunch                  : first sequential — boots singleton.
//   - TestInstanceClusterStats / Metadata
//     / SSHProbe / ConsoleOutput          : read singleton.
//   - TestVolumeLifecycle / VolumeStatus  : attach to singleton.
//   - TestSnapshotLifecycle /
//     SnapshotBackedLaunch / CreateImage  : snapshot singleton.
//   - TestSecurityGroupEgress             : mutates default SG.
//   - TestStopStart / AttachToStoppedError
//     / ModifyInstanceAttribute /
//     RebootInstance / RunInstancesMultiCount : mutate singleton state.
//   - TestNegativeErrorPaths              : sub-tests already parallel inside.
//   - TestNATGateway / TestSGToSGDatapath : share EIP pool.
//   - All TestIAM*                        : share IAM policy state via the
//     package-scoped IAM fixture; sub-tests inside each already parallel.
//   - TestFinalClusterStats               : final sanity gate.
