Live verification on a Windows VM surfaced a crash loop: TcpFrameServer.EnsureListening
assigned _listener = new TcpListener(...) BEFORE calling Start(). When Start() throws —
e.g. the port is in a Windows excluded/reserved range (WSAEACCES) or already in use — the
field was left non-null-but-unstarted, so the `if (_listener is not null) return` guard
permanently skipped re-Start() and every subsequent AcceptTcpClientAsync() threw the
misleading InvalidOperationException "Not listening" → 20 failures → exit 2 → NSSM restart
→ loop. Now _listener is assigned only after Start() succeeds, so a transient bind failure
is retried and a permanent one surfaces the real bind error each iteration. Adds a
regression test that forces a bind conflict and asserts the SocketException persists.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
- Driver.Historian.Wonderware-004: ToHistorianEvent synthesises a fresh
Guid when the upstream EventId is unparseable and logs the substitution
instead of writing the historian with Guid.Empty.
- Driver.Historian.Wonderware-005: GetHealthSnapshot derives the
connection-open booleans from the active-node fields so the snapshot
is self-consistent without depending on the secondary lock.
- Driver.Historian.Wonderware-007: SID-mismatch branch in PipeServer now
sends a HelloAck { Accepted=false, RejectReason } so the client sees a
symmetric rejection.
- Driver.Historian.Wonderware-008: classify StartQuery failures —
connection-class codes drop the connection, query-class codes throw
QueryClassStartQueryException so the IPC layer surfaces Success=false.
- Driver.Historian.Wonderware-010: RequestTimeoutSeconds now enforced
via BuildRequestCts linked to the caller's CancellationToken.
- Driver.Historian.Wonderware-011: refreshed XML docs to describe the
current sidecar / named-pipe architecture (Galaxy.Host / Proxy
references reframed as historical context).
- Driver.Historian.Wonderware-012: pinned the previously-uncovered
HistorianDataSource behaviours with five new test files; also removed
the stale empty tests/ZB.MOM.WW.OtOpcUa.Driver.Historian.Wonderware.Tests
directory.

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
