# coverage_matrix.sh --- Comprehensive PKCS#11 function × mechanism × error
# matrix exercise for FreeHSM C.
#
# Generates a coverage report : every C_* function is invoked against every
# wired mechanism (plus some error paths), and the result is recorded.
#
# Use cases :
#   - Self-attestation for FIPS 140-3 §7.11 functional testing.
#   - Regression detection (CI).
#   - Pre-cert evidence for the NIST CST lab.
#
# Sections :
#   1. Module identity   (Initialize, GetInfo, GetSlotList, GetSlotInfo)
#   2. Session lifecycle (OpenSession, Login, Logout, CloseSession)
#   3. Object lifecycle  (GenerateKey, FindObjects, GetAttribute, Destroy)
#   4. Crypto ops        (Encrypt/Decrypt, Sign/Verify, Digest) per mechanism
#   5. Key wrap          (WrapKey, UnwrapKey) per wrap mechanism
#   6. Key derive        (DeriveKey for ECDH1)
#   7. PQ ops            (Encapsulate, Decapsulate, ML-DSA, SLH-DSA)
#   8. Error paths       (CKR_PIN_INCORRECT, CKR_TOKEN_NOT_PRESENT,
#                         CKR_OBJECT_HANDLE_INVALID, CKR_MECHANISM_INVALID,
#                         CKR_SIGNATURE_INVALID, CKR_KEY_TYPE_INCONSISTENT)
#
# Output : tab-delimited matrix written to /tmp/freehsm-coverage.tsv :
#           function<tab>mechanism<tab>status<tab>note
#
# Exits 0 if all expected-PASS rows pass and all expected-FAIL rows fail.

# ECDH derive
#
# Historical flakiness note : this test was reported intermittent in CI
# (about 1 failure per 5 runs) before the v1.1.18 hardening below. The
# root cause was environmental, not a bug in C_DeriveKey :
#   - The output file `/tmp/cov-z.bin` could carry stale 0-byte content
#     from a previous matrix invocation on the same CI runner.
#   - The pkcs11-tool exit code was not checked ; only the file size
#     was. A transient pkcs11-tool failure that still touched the file
#     could appear as a 0-byte success.
#   - The CI container can swap under load, occasionally delaying the
#     write completion past the `[ -s file ]` check.
#
# Hardening applied :
#   1. Clean the output file before the derive call (eliminates stale
#      state).
#   2. Capture the pkcs11-tool exit code AND check the file size
#      (defence in depth).
#   3. Retry once on failure (covers the rare CI swap-induced timing
#      glitch).
