Integration-sweep follow-up #6 (SQL leg). The sweep flagged 7 heavy 2-node
deploy/failover/reconnect E2E tests as 'time out under amd64-emulated SQL' and
suggested raising deadlines. That diagnosis was WRONG: run against real
(native-amd64) SQL on the Docker host, they still hang — even at 4x deadline.
Root cause is that these tests had never actually run against real SQL, only the
EF in-memory provider, which does NOT enforce foreign keys.
Two distinct defects, both hidden by in-memory:
1. Missing FK-parent seed (5 tests). The deploy records a NodeDeploymentState row
per node, FK'd to ClusterNode (FK_NodeDeploymentState_ClusterNode_NodeId). The
tests never seeded ServerCluster + ClusterNode, so on SQL each node-state INSERT
throws and the deploy never seals (waits the full deadline regardless of size).
Added TwoNodeClusterHarness.SeedDefaultClusterAsync (seeds a ServerCluster +
a ClusterNode per node; Warm/NodeCount=2 to satisfy the SQL CHECK constraint
CK_ServerCluster_RedundancyMode_NodeCount AND the ClusterEnabledNodeCountMismatch
validator). Called it in DeployHappyPath x2 / Failover / FleetDiagnostics /
EquipmentNamespace; fixed DriverReconnect to seed node B + NodeCount=2.
2. Stale EquipmentId (EquipmentNamespace test; pre-existing on BOTH providers).
Seeded EquipmentId='eq-1', but the later-added EquipmentIdNotDerived validator
requires EquipmentId == DeriveEquipmentId(EquipmentUuid) ('EQ-'+first 12 hex).
Fixed the seed to a canonical id + matching UUID. Only surfaced once the FK fix
let the deploy reach equipment validation.
Also added OTOPCUA_HARNESS_SQL_HOST / OTOPCUA_HARNESS_LDAP_HOST overrides so the
harness fixtures can run on the native-amd64 Docker host (avoids arm64 mssql
emulation entirely).
Verified: the 5 SQL-backed classes go 11/11 green vs native SQL; in-memory default
unregressed (12/12). RoslynVirtualTagEvaluatorTests racing test is a pre-existing
flaky race (not SQL-backed; passes in isolation) — left as-is.
The OPC UA address-space build pipeline was named after a v2-roadmap
milestone number rather than its domain. Rename the family to describe
what it does (build/diff/apply the OPC UA address space):
Phase7Composer -> AddressSpaceComposer
Phase7CompositionResult -> AddressSpaceComposition
Phase7Planner -> AddressSpacePlanner
Phase7Plan -> AddressSpacePlan
Phase7Applier -> AddressSpaceApplier
Phase7ApplyOutcome -> AddressSpaceApplyOutcome
The 9 Phase7*Tests suites follow suit; Phase7ScriptingEntitiesTests ->
ScriptingEntitiesTests (it tests the scripting migration, not the
pipeline). Log-message prefixes move to the new class names.
Pure mechanical rename, no behavioral change. EF migration classes/IDs
(AddPhase7ScriptingTables, ExtendComputeGenerationDiffWithPhase7) are
immutable and left untouched, as are historical design docs.
Build clean; OpcUaServer 261/261, Runtime 272/272, ScriptingEntities
12/12 green.
Seed a 1-area/1-line/1-equipment/1-tag Equipment namespace, StartDeployment via the
in-process 2-node harness, and assert the persisted artifact decodes (ParseComposition)
to the equipment signal (FullName from TagConfig) + friendly UNS folder names. Covers the
ConfigComposer -> ArtifactBlob -> ParseComposition.EquipmentTags seam the unit tests only
approximated with hand-built JSON. (OPC UA browse is covered against a real SDK node manager
in Phase7ApplierHierarchyTests; the cluster harness binds the no-op sink.)
