Operator: 'the scanner should not say 0 when it was not able to scan.' Correct — the
previous patch still led with '0 identified' and relegated the caveat to a footnote,
so the headline number was wrong even though the prose was right. A 0 in a security
column is an assertion of safety; it must never be emitted for an undetermined result.
Now: cve_count_fixed is null (not 0) in JSON, a count_known flag distinguishes
'counted zero' from 'could not count', and the markdown headline reads
'CVEs fixed by this upgrade: UNKNOWN — the scan could NOT determine a count' with an
explicit 'This is NOT zero' and instructions to render '?'.
Verified: discourse 3.5.3 -> 2026.7.1 (semver->calver) now reports UNKNOWN; gitea
1.27.0 -> 1.27.1 still reports 2.
