UnsTabDragDropE2ETests were timing out at the 'UNS Structure' nav-link
locator because AdminWebAppFactory never registered AdminHubConnectionFactory
/ HubTokenService / DataProtection — ClusterDetail.razor's @inject threw at
circuit boot, so the page never advanced past the Loading placeholder. 2 → 3
pass after the registrations land. Also documents the Modbus standard-vs-
exception_injection coverage matrix in the fixture README + cross-references
docs/drivers/AbServer-Test-Fixture.md from each Emulate test so a developer
landing on a skipped test has a direct doc pointer.

Two real bugs uncovered by re-running with the new fixture defaults
pointing at the shared docker host. Both are test-side, not driver-side.
AbCip — Driver_reads_seeded_DInt_from_ab_server (4 parametrized rows):
Hardcoded 'ab://127.0.0.1:{port}/1,0' in the deviceUri instead of
the resolved fixture.Host. The new 10.100.0.35 default (and any
AB_SERVER_ENDPOINT override) silently couldn't reach this test —
the driver tried to connect to a non-existent localhost:44818 and
returned BadCommunicationError on all 4 profile rows. The sibling
Emulate tests already use the fixture's resolved endpoint; this
smoke test was missed in the original migration.
Fix: deviceUri = $"ab://{fixture.Host}:{fixture.Port}/1,0".
Modbus — Float32_With_CDAB_Roundtrips_Through_Wire:
Test wrote a Float32 to HR 100 (2 consecutive registers: 100+101).
standard.json's writable HR range declares [100,100] only — a
single-cell auto-incrementing register, not a 2-register pair. The
write to register 101 was rejected with Illegal Data Address
(BadOutOfRange).
Fix: moved the tag from HR 100 to HR 200 (in standard.json's
'[200, 209]' scratch range — 10 consecutive writable HRs). The
Float32+CDAB semantic the test exercises is unchanged.
Modbus — Block_Read_Coalescing_Reduces_PDU_Count_End_To_End:
Test read HR 300, 302, 304 — outside both the writable ranges and
the uint16 seed list. pymodbus rejects reads to unseeded HRs even
though 'hr size' is 2048. BadOutOfRange on every read.
Fix: moved the tags from 300/302/304 to 200/202/204 (within the
scratch range). The non-contiguous coalescing semantic (3 tags
inside a 5-register window with MaxReadGap=5) is preserved.
After this commit:
- Modbus.IntegrationTests: 6/38 pass / 32 skip / 0 fail
(was 4 pass / 32 skip / 2 fail; 32 skips are profile-gated
ExceptionInjectionTests — they need MODBUS_SIM_PROFILE=
exception_injection and a different container, intentional gating)
- AbCip.IntegrationTests: 10/12 pass / 2 skip / 0 fail
(was 6 pass / 2 skip / 4 fail; 2 skips are Emulate tests that
need the fixture for separate scenarios)
No driver code changed.

CLAUDE.md "Docker Workflow" claims (per the 2026-04-28 migration note)
that all fixture-class default endpoints were rewritten to target the
shared Docker host at 10.100.0.35. Audit during today's e2e run showed
the claim was incomplete — five fixture classes still defaulted to
localhost / 127.0.0.1, causing every fixture-touching integration test
to skip with "endpoint unreachable" on a fresh box that hadn't set
the override env vars.
Files corrected:
- tests/.../Modbus.IntegrationTests/ModbusSimulatorFixture.cs
DefaultEndpoint: localhost:5020 → 10.100.0.35:5020
- tests/.../S7.IntegrationTests/Snap7ServerFixture.cs
DefaultEndpoint: localhost:1102 → 10.100.0.35:1102
- tests/.../OpcUaClient.IntegrationTests/OpcPlcFixture.cs
DefaultEndpoint: opc.tcp://localhost:50000 → opc.tcp://10.100.0.35:50000
- tests/.../AbCip.IntegrationTests/AbServerFixture.cs
Host default + ResolveHost fallback: 127.0.0.1 → 10.100.0.35
- tests/.../AbLegacy.IntegrationTests/AbLegacyServerFixture.cs
Host default + ResolveEndpoint fallback: 127.0.0.1 → 10.100.0.35
XML doc comments referencing the old localhost defaults were updated in
the same pass so the class-summary documentation matches the actual
default. The override-via-env-var mechanism (MODBUS_SIM_ENDPOINT,
AB_SERVER_ENDPOINT, AB_LEGACY_ENDPOINT, S7_SIM_ENDPOINT,
OPCUA_SIM_ENDPOINT) is unchanged — pointing at a real PLC or a
locally-running container still works exactly as before.
Verification:
- Solution-wide dotnet build: 0 errors.
- S7.IntegrationTests: 3/3 pass without env-var override.
- OpcUaClient.IntegrationTests: 3/3 pass without env-var override.
- Modbus.IntegrationTests: 4/38 (same as the env-var-override run —
the 2 failures + 32 skips are pre-existing fixture-profile
mismatches unrelated to this fix).
- AbCip.IntegrationTests / AbLegacy.IntegrationTests: same results
as the env-var-override run.

Rewrite src/ and tests/ project paths in docs, CLAUDE.md, README.md, and
test-fixture READMEs to the new module-folder layout (Core/Server/Drivers/
Client/Tooling). References to retired v1 projects (Galaxy.Host/Proxy/Shared,
the legacy monolithic test projects) are left untouched.

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.
