The SDK-mode regression tests (audit, F-08/F-10/F-11/F-12, pq-box, KDF transparency) now skip cleanly when built without libzuptsdk, and the constant-time test links libzuptsdk only when present (its primitives are native). Also drop a dead 'seqs_decoded' variable in vv_ans.c that failed the exact-size test's -Werror=unused-but-set-variable. 'make check' is green source-only, so the openSUSE %check no longer blocks the build.

# F-11 regression test (Zupt 2.4.2).

#
|
|
# F-11: pre-2.4.2 the AIT-fail message said "archive header or footer has
|
|
# been tampered with" in both the actual-tamper case AND the wrong-password
|
|
# case (because wrong password → wrong mac_key → AIT mismatch). This
|
|
# misled users into thinking valid archives were corrupted when they had
|
|
# just mistyped a password.
|
|
#
|
|
# v2.4.2 collapses both cases into the same generic message by default:
|
|
# "Authentication failed (wrong key, wrong password, or tampered archive)"
|
|
# and moves the detailed top-MAC wording behind --verbose. Identical
|
|
# message for both cases eliminates a verbal probe-oracle. Plaintext-mode
|
|
# tamper detection (no key involvement) keeps detailed wording.
