ecf6b628 pinned AngleSharp to 1.5.2 to clear GHSA-pgww-w46g-26qg. That fixed the
build but BROKE 33 CentralUI bunit tests at runtime with
MissingMethodException: AngleSharp.Dom.IHtmlCollection`1.get_Item(Int32)
because 1.5.x changed IHtmlCollection<T>'s indexer and bunit is compiled against
1.1.x. My mistake: I verified `dotnet build` was clean and did not run the test
suite before committing, so a runtime-only break sailed through.
There is no working patched combination upstream. Verified empirically:
AngleSharp 1.1.2 / 1.2.0 / 1.3.0 / 1.4.0 -> still flagged NU1902
AngleSharp 1.5.0 / 1.5.2 -> patched, but breaks bunit at runtime
bunit up to 2.7.2 (latest) -> still resolves AngleSharp 1.4.0
So the real choice is a suppressed advisory or an unbuildable suite. Scoped
suppression wins here because the reach is nil: AngleSharp is an HTML parser bunit
uses to assert on rendered markup, it ships in no production project, and the only
"documents" it parses are our own components' output.
Explicitly NOT the same call as GHSA-2m69-gcr7-jv3q (SQLitePCLRaw), whose
suppression was removed in 2026-07: that one masked a vulnerability on PRODUCTION
code paths and had a working patched version available. Neither is true here.
Revisit when bunit ships against AngleSharp 1.5+.
Verified:
dotnet build ZB.MOM.WW.ScadaBridge.slnx -> 0 Error(s), 0 Warning(s)
CentralUI.Tests -> 925 passed, 0 failed (was 33 failing)

GHSA-pgww-w46g-26qg (NU1902, moderate) on AngleSharp 1.1.1, pulled in
transitively by bunit into CentralUI.Tests. Under TreatWarningsAsErrors this
made `dotnet build ZB.MOM.WW.ScadaBridge.slnx` fail on a CLEAN main - the whole
suite was unbuildable and every "0 warnings / suite green" gate unverifiable.
Pre-existing, not introduced here; surfaced while starting LocalDb Phase 1,
whose per-task verification depends on a green baseline.
Same fix as the identical break in HistorianGateway (historiangw @ 6bc005d):
pin the leaf, test-only. AngleSharp is a bunit HTML-parsing dependency and
reaches no production project. Bumping bunit does not help - 2.0.33-preview is
the current preview line and still resolves the vulnerable AngleSharp.
Verified: dotnet build ZB.MOM.WW.ScadaBridge.slnx -> 0 Error(s), 0 Warning(s)
(was 1 Error before this commit).

The NuGetAuditSuppress in Directory.Packages.props was masking a LIVE high-severity
vulnerability, not documenting an accepted one. Only the Host project resolved a
patched SQLitePCLRaw.lib.e_sqlite3 2.1.12 (transitively, via ZB.MOM.WW.Auth.ApiKeys).
Every other SQLite consumer - AuditLog, SiteRuntime, StoreAndForward, SiteEventLogging
and 11 test projects - still resolved the vulnerable 2.1.11.
The suppression's rationale was factually wrong: it claimed 'the only patched native
lib is the SQLitePCLRaw 3.x line'. 2.1.12 patches this advisory within the 2.1.x line,
so the feared risky force-override of the whole family to 3.x is unnecessary.
Fix: explicit PackageReference to the patched 2.1.12 in each SQLite-consuming project,
plus the central PackageVersion row. Suppression removed, so the advisory is audited
again rather than silenced.
Rejected alternative: CentralPackageTransitivePinningEnabled. It clears the advisory in
one line but makes every central version a ceiling for transitive resolution, demanding
bumps to Google.Protobuf, Grpc.Net.Client, Microsoft.Data.SqlClient and Newtonsoft.Json.
That is a gRPC/data-access change to a production SCADA platform and deserves its own
reviewed commit.
Verified: forced full-solution restore reports no NU1903 (only the pre-existing,
unrelated AngleSharp NU1902 in CentralUI.Tests); all four previously-vulnerable src
projects now resolve 2.1.12; 55 projects build 0 warnings / 0 errors; 1108 tests pass
across the SQLite layer (AuditLog 354, ConfigurationDatabase 357, Security 181,
StoreAndForward 152, SiteEventLogging 64).
