Nothing read the mapping table beyond the startup validator; v3 UNS projection is
explicit via UnsTagReference. Legacy keys in stored DriverConfig are ignored (pinned).

`OpcUaClientTagDefinitionFactory.TryReadNodeId` still honours a legacy PascalCase
`NodeId` when the v3 camelCase `nodeId` is wholly absent, but
`OpcUaClientTagConfigModel` read only `nodeId` — so a legacy blob was SERVED by
the driver yet opened with an empty reference field and could not be saved
untouched. Authoring stricter than the reader, which #554 names as never
legitimate: the editor was blocking config the runtime honours.
Fixed with the #550 pattern (read both spellings, normalise on save), NOT by
retiring the spelling from the reader — that would break every legacy blob the
driver currently serves at the next deploy, a data-plane regression traded for
an editor asymmetry.
The precedence is PRESENCE-shadows, not first-non-blank. The reader's
`TryGetProperty("nodeId", out n) || TryGetProperty("NodeId", out n)`
short-circuits on the mere PRESENCE of the camelCase key and then checks
string-and-non-blank ONCE, so a blank / non-string / JSON-null `nodeId` beside a
valid legacy `NodeId` is a REJECTED blob, not a fallback. Copying MTConnect's
`FirstNonBlank` walk here would have made authoring WEAKER than the reader —
the same defect in mirror image.
- `NodeIdKeys` drives both halves, so the read and the drop cannot drift.
- `ToJson` writes `nodeId` and drops `NodeId`; the TagModal history-merge keys
(`isHistorized` / `historianTagname`) are disjoint and untouched.
- `Validate`'s required-reference fast path is now precedence-aware by
construction, so it agrees with the #554 parse consult across the whole
rejection surface.
- The `TagConfigNonEnumParityTests` exemption for OpcUaClient is REMOVED — its
anti-vacuity guard `Every_deliberately_stricter_entry_is_still_exactly_that`
went red on the fix, which is this change's falsification control. The legacy
shapes moved into the corpus, where both fleet theories now cover them.
Tests: a nine-row precedence theory driving the authoring verdict against the
READER's verdict per shape, on the original blob AND on the `ToJson()` output;
no-retype (legacy loads showing its reference, saves canonical, same node id
before and after); no-drift (output never carries `NodeId`). Each half was
reverted in isolation to confirm it reddens tests of its own: read-only-revert
=> 6 red incl. the fleet parity theory; drop-only-revert => 4 red.
Suites: AdminUI.Tests 1459/1459, ControlPlane.Tests 261/261,
Driver.OpcUaClient.Tests 143/143, Driver.OpcUaClient.Browser.Tests 10/10.
G-7 wired OpcUaClientTagDefinitionFactory.Inspect into the deploy-time TagConfig
gate, which gave ControlPlane a ProjectReference to
Driver.OpcUaClient.Contracts — and with it, transitively, the whole OPC UA client
stack (5 OPCFoundation packages) into every host that loads the control plane.
NamespaceMap was the only reason Contracts carried
OPCFoundation.NetStandard.Opc.Ua.Client: its entire public surface is
ISession/NamespaceTable/NodeId-typed. It moves to a new leaf project,
ZB.MOM.WW.OtOpcUa.Driver.OpcUaClient.Session, referenced by the runtime .Driver
and by .Browser. Contracts is left with Core.Abstractions and NOTHING else —
the same shape as Calculation.Contracts.
The namespace stays ZB.MOM.WW.OtOpcUa.Driver.OpcUaClient, so no consumer's
`using` changed. The .Session -> .Contracts direction is deliberate: the blob
read NamespaceMap needs is OpcUaClientTagDefinitionFactory.TryReadNodeId, the
one authority it shares with the deploy gate, and that must stay in the
dependency-light half.
Why a new project rather than folding NamespaceMap into the runtime .Driver and
having .Browser reference it (the Driver.Mqtt.Browser #512-style deliberate
exception): the AdminUI project-references .Browser and NOT .Driver, so that
shape would pull the OpcUaClient driver runtime — plus Core,
Opc.Ua.Configuration and Secrets.Abstractions — into the AdminUI's build/deploy
graph. That is exactly the violation #512 spent two extractions removing from
Mqtt.Browser; re-introducing it to save one csproj is a bad trade.
Guard: ContractsIsDependencyLightTests (Driver.OpcUaClient.Tests) asserts the
Contracts manifest names no Opc.Ua* assembly, plus a counterpart asserting
.Session does. An ABSENCE assertion is sound on the manifest where a presence
one is not — the compiler elides an unused reference, but it MUST emit one the
moment Opc.Ua-typed code is added. Falsified by temporarily re-adding the
package plus an Opc.Ua.NodeId-typed member: red on Opc.Ua.Types, green again on
removal.
Evidence — `dotnet list ControlPlane package --include-transitive | grep -i opc`:
before: OPCFoundation.NetStandard.Opc.Ua.{Client,Configuration,Core,
Security.Certificates,Types} 1.5.378.106
after: none (and 0 Opc.Ua*.dll in ControlPlane's output directory)
Deferment-register G-7: these four were validated by the AdminUI's TagConfigValidator at
authoring but by nothing at deploy, so config arriving by CSV import or API met no gate at
all. The deploy gate dispatches to a driver's *TagDefinitionFactory.Inspect in its Contracts
assembly, and none of the four had one.
Rather than mirror the AdminUI models (a mirror of an accept/reject boundary drifts silently,
with the gate describing a shape the driver no longer reads), each Inspect is built on the
driver's own runtime parse:
- Sql wraps the existing SqlEquipmentTagParser, which already lived in Sql.Contracts. The
P3-deferred Query model stays refused; Inspect surfaces the refusal rather than weakening it.
- MTConnect's blob reader MOVED out of MTConnectDriver (it was private, with a private DTO)
into MTConnectTagDefinitionFactory; the driver now calls it. Behaviour unchanged.
- OpcUaClient's nodeId read MOVED off NamespaceMap into OpcUaClientTagDefinitionFactory;
NamespaceMap now calls it. Behaviour unchanged.
- Calculation gains a Contracts assembly it never had. Only the JSON reading moved there
(CalculationTagDefinitionFactory.TryReadTagConfig); building a CalculationTagDefinition
still needs EquipmentScriptPaths from Commons and stays in the driver, so the split is at
the blob boundary. The new project is deliberately reference-free — a calc blob is strings,
a bool and an int, with no Core.Abstractions type in it.
Each Inspect runs the parse FIRST and returns empty on success, so "never stricter than the
runtime" is structural rather than a promise: a warning is only reachable for a blob the
driver would have refused and then skipped silently. Calculation additionally reports two
present-but-silently-discarded fields (a non-boolean changeTriggered reads as true; a
non-positive-integer timerIntervalMs is dropped), and deliberately does NOT warn about a
trigger-less tag or a sub-50ms timer — the editor refuses both, the runtime honours both, and
the deploy gate follows the runtime.
Resolve secret:-prefixed Password + UserCertificatePassword through the shared
ISecretResolver, fail-closed on absent, retiring the cleartext-in-DB path. The
driver-registry factory is synchronous (Func<string,string,IDriver>), so resolution
is done lazily in the async session-open (InitializeAsync, before BuildUserIdentity)
rather than at deserialize — mirroring Task 7's Galaxy pattern and matching its
re-resolve-on-reconnect behavior. Both consumers (username Password and the
certificate-password LoadPkcs12 path via BuildCertificateIdentity) see the resolved
connect-scoped options; _options stays raw (secret: refs intact), no long-lived
plaintext field.
Scope corrections vs the plan (verified against v3): the probe is unauthenticated
GetEndpoints-only and never reads either credential, so it is NOT a resolution site
(comment added, no dead code); OpcUaClientDriverOptions was a sealed class, converted
to sealed record for the with-expression (no positional params → identical JSON; no
reference-equality/dict-key/ToString-log usages → no behavior/leak change).
ISecretResolver threaded via factory Register/CreateInstance + DriverFactoryBootstrap
(real resolver from DI); NullSecretResolver null-object backs test/parse paths only,
fail-closed on secret: refs. TDD: 4 helper tests RED→GREEN; 142 OpcUaClient tests pass.
NamespaceMap now carries a RawPath -> upstream node id table built from the
deployed RawTagEntry list (reads each tag's TagConfig.nodeId, threads
WriteIdempotent). Under v3 the read/write/subscribe/history reference handed to
the driver is the tag's RawPath identity; the driver resolves it in two stages:
RawPath -> nodeId string (instance TryResolve) -> live NodeId re-bound against
the session (static TryResolve). Alarm ConditionId + event-history sourceName
stay on the direct session parse (they are upstream node ids, not RawPaths).
- Options: add IReadOnlyList<RawTagEntry> RawTags (Contracts now refs Core.Abstractions).
- Factory: RawTags binds straight into options (no separate DTO); EndpointUrl kept.
- Browser: unchanged (emits neutral BrowseNode DTOs, no TagConfig FullName key).
- Tests: 138 green; new RawPath resolution + factory-binding coverage; migrated
the stale-session ReadRaw test to author a resolving RawTag.
Contracts + Driver + Browser build clean (0 warn). Wave C wires endpoint->DeviceConfig
and the deploy artifact that populates RawTags.
Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
First review at 7286d320. -001 (Medium): TryResolve session param -> ISession? matching the
null guard + out-contract doc. -003: [Range] on MaxDiscoveredNodes/MaxBrowseDepth, drop dead
[Display]. -002 (NamespaceMap pulls full SDK into a DTO project) Open. Surfaced cross-module:
the OpcUaClient.Browser serializer lacks JsonStringEnumConverter (enum-as-int bug).
Browser project (Phase 3) needs to share namespace-stable address encoding
with the runtime driver. Move keeps the same namespace, so existing usages
in OpcUaClientDriver compile unchanged.
Move OpcUaClientDriverOptions and all companion enums (OpcUaTargetNamespaceKind,
OpcUaSecurityMode, OpcUaSecurityPolicy, OpcUaAuthType) to a new
Driver.OpcUaClient.Contracts sibling project. The options file had no
using directives — all types were defined in the same file — so no
NuGet mirror enum pattern was required.
Convert two doc-comment references:
<see cref="OpcUaClientDriver.InitializeAsync"/> → <c>OpcUaClientDriver.InitializeAsync</c>
<see cref="OpcUaClientDriver.ValidateNamespaceKind"/> → <c>OpcUaClientDriver.ValidateNamespaceKind</c>
per the approved decision — no compilable usings were present.
The runtime Driver.OpcUaClient project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
