Code review (correctness lens) found a P0 in tests/test_attestation_matrix.py
introduced by the P5 fallback-removal pass: the dual-read delenv of
ACDL_ATTESTATION_SIGNING_KEY_ID was replaced with a second (duplicate)
delenv of NOVA_ATTESTATION_SIGNING_KEY_ID, leaving the test misleading
(comment claimed 'both NOVA_* and ACDL_* must be unset' while only NOVA_*
was deleted twice) and the ACDL_* var no longer cleaned. With P5 having
removed the ACDL_* fallback from core/env.py, deleting NOVA_* alone is the
correct and sufficient precondition for the skip; this commit drops the
duplicate line and updates the comment to match the NOVA-only contract.

milestone: v1.15
status: verify
lessons:
- P0 fix applied: duplicate monkeypatch.delenv('NOVA_ATTESTATION_SIGNING_KEY_ID') in test_signature_skip_when_key_unset left the test misleading and the ACDL_* var uncleaned; collapsed to a single NOVA_* delenv consistent with the P5 NOVA-only core/env.py.
