Fixture Base-Image Update

Re-pins two values that must stay in lockstep:

  1. The FROM cgr.dev/chainguard/wolfi-base:latest@sha256:... line in
    every tests/e2e/fixtures/*/Dockerfile.
  2. The pinned wolfi-base digest constant asserted by
    TestParseWolfiBaseRef in tests/oscap-offline/internal/scan/fixtures_test.go.

If these drift (e.g. Dependabot bumps the fixture digest without the
test pin following), the offline harness unit tests break. This
workflow is the authoritative update point for both together;
TestParseWolfiBaseRef was run against the updated tree before this
PR was opened.

CertificateAudit itself no longer pins any hash — the OVAL reads each
expected digest from the stamp file shipped beside the file it
describes inside the scanned image
(/etc/ssl/certs/.ca-certificates.crt.sha256, and on Java images
/etc/ssl/certs/java/.cacerts.sha256). The Verify trust-store stamp files step above asserts both are present and agree, using
cgr.dev/chainguard/jre:latest because it carries both, so an image
that dropped one would fail this run rather than silently red the
E2E CertificateAudit assertions.

  • Image: cgr.dev/chainguard/wolfi-base:latest
  • Digest: sha256:08df5982c3d27e70a4ce1607e3bb9af09d746f8722cf135a7694afef879fc5a2
  • Stamp image: cgr.dev/chainguard/jre:latest
  • Stamp image digest: sha256:2918018b3ee119801c892e41622fe2248959a5c7b2ed77aad06cc7639b397255
  • CA SHA256: 028fca5150ee1915c4474489985d55c54fceaa680c754cc8d1301734f01b2232
  • Fixtures changed: true
  • Test pin changed: true

Re-pins the digest-pinned FROM lines in tests/e2e/fixtures/*/Dockerfile
and the pinned wolfi-base digest in the offline harness test
(TestParseWolfiBaseRef) together, so the two can never drift out of
sync and break the offline unit tests.

Both stamp files CertificateAudit reads were checked first, on
cgr.dev/chainguard/jre:latest: the CA bundle matches
/etc/ssl/certs/.ca-certificates.crt.sha256 and the Java truststore
matches /etc/ssl/certs/java/.cacerts.sha256.
