// aws-sdk-go-v2 changed its defaults in 2025: RequestChecksumCalculation and
// ResponseChecksumValidation now default to "when_supported", so the SDK tries to
// validate a checksum on every S3 GET. Pulumi state objects stored without a checksum
// (all pre-existing state) make the DIY backend's in-process s3blob client emit a noisy
// "Response has no supported checksum. Not validating response payload" WARN per object.
// Force "when_required" — matching the GCS bucket compatibility settings in gcp/bucket.go —
// to silence the noise without changing behavior (state reads/writes don't require checksums).
