The 9cad9ed0 'strip tracking-ID comments' XML-doc sweep collaterally
removed the comment explaining why the S7 subscribe command routes
OnDataChange through the CliFx IConsole (not System.Console), leaving
SubscribeCommandConsoleHandlerCommentTests red. The Modbus copy still
carries the comment verbatim and the test guards S7-mirrors-Modbus
parity, so restore it (matching the Modbus wording) rather than weaken
the guard.
S7.Cli tests 49/49.
The historian's Int1 analog-tag creation path is server-degenerate:
EnsureTags(Int1) stores an unusable stub (live-probed on the deployed
2023 R2 historian; root-caused + documented gateway-side in
HistorianGateway #11 / PR #16). HistorianTypeMapper mapped
DriverDataType.Boolean -> HistorianDataType.Int1, so Boolean historized
tags failed auto-provisioning.
Map Boolean -> Int2 instead (store 0/1). Int2 is a proven-creatable
analog type, and the value-write path already sends every value as a
double on WriteLiveValues regardless of tag type, so Boolean 0.0/1.0
round-trips cleanly. Both Float and Int2 are supported, so a
pre-existing Float Boolean tag retypes cleanly on its next deploy.

Fixes the historized-tag provisioning path that silently failed at the gateway
(StorageRateMs=0 -> ArgumentOutOfRangeException). Found via the R2-06 live gate.
GatewayTagProvisioner built HistorianTagDefinition without a StorageRateMs, so
the proto uint32 defaulted to 0. The gateway's EnsureTags maps StorageRateMs
straight to the AVEVA SDK's storageRateMs, which requires a positive value —
0 makes the SDK throw ArgumentOutOfRangeException ('Storage rate must be > 0 ms'),
so EVERY historized-tag auto-provision (the deploy-time IHistorianProvisioning
hook) silently failed at the gateway with failed=N.
Stamp DefaultStorageRateMs=1000 (matches the gateway's own live provisioner
convention; quantized 1000/5000/10000). Add a regression unit test asserting the
definition carries a positive rate, and set StorageRateMs on the live-suite's
inline definitions so the retype probe reaches a real EnsureTags.
Found via the R2-06 live gate against a real 0.2.0 gateway + AVEVA historian:
with this fixed, Float/Int2/UInt2/Int4/UInt4/Double all provision and the live
suite goes 3/6 -> 5/6. (Int1/Boolean remains blocked by the gateway histsdk's
ProtocolEvidenceMissingException for Int1 — a gateway-side type-support gap, not
this bug.)
Gateway driver unit 103/103.
Four continuous-historization types (IHistorizationOutbox, HistorizationOutboxEntry,
IHistorianValueWriter/HistorizationValue, HistorizationCommitMode) drifted into a
ZB.MOM.WW.OtOpcUa.Core.Abstractions.Historian sub-namespace while the other six files
in the same folder correctly use the root namespace. This violated decision #59's
flat-public-surface rule and left InterfaceIndependenceTests.AllPublicTypes_LiveInRootNamespace
red on master (pre-existing, predates round-2 remediation).
Move all four to the root namespace and drop/retarget the now-redundant
'using ...Core.Abstractions.Historian;' in the ~11 consumers. No behavioral change.
Verified: Core.Abstractions.Tests 129/129 (was 128/129), Runtime.Tests Historian+DI 72/72,
Gateway driver unit 102/102, full solution build 0 errors.
R2-10: driver failures propagate through the full Polly pipeline (CircuitBreaker->
Retry->Timeout->CapabilityInvoker.cs:84) live — the #10 dispatch-gap fix + tracker
source confirmed in prod; breaker-OPEN not forced (backoff-throttled, per FOLLOWUP-10).
R2-03: rig has no driver data (all nodes Bad_WaitingForInitialData), so VT Good->Bad
can't be staged; unit-verified. 5 gates live-confirmed total; remaining items need
external infra (integration fixtures, VPN gateway, live LDAP, S7 blackhole).
All 12 R2 plans executed + merged (PRs #426-#437) in 3 waves. Consolidated unit
sweep green on merged master; 3 failures confirmed pre-existing/environmental (not
R2). Records the PR/wave map, unit-sweep tallies, and the deferred integration /
docker-dev / 2-node-rig / VPN heavy-pass checklist.
