Marc Schier 7c965fd636 Capture metadata images and generation-bound session clients (#4752)
# Description

- Add isolated NodeState reference images, TypeTable graph snapshots,
EncodeableFactory registration forks/views, StringTable mutation
versions/private copies, and ServiceMessageContext mapping-holder
generation tracking. Reference images are lazy for empty nodes;
selected-image clones own independent storage and publication ownership.
- Add the complete generic NodeBrowser continuation-dependency
capability. This does not implement server browse-history retention,
NodeManager read images, or server batch/readiness admission.
- Add optional client binding capture for SessionClient, native Session
and ManagedSession, with managed-lease/native-channel generation
composition. Bindings capture authenticated-session identity, mapping
holders/versions and owned endpoint/policy/configuration observations.
Replacement, reconnect, mapping ABA and disposal permanently invalidate
stale bindings; disposing a binding does not dispose its owner.
- Preserve cancellation and master pooled-response ownership: a rejected
pooled response is released exactly once; an accepted response remains
caller-owned. Keep native transport submission under its replacement
gate and completion outside the gate, without routing ordinary unbound
requests through binding machinery.
- Rename the existing server lookup interface and all actual consumers
with minimal hunks; add focused fixtures, generated FileTypeClient usage
guidance, and package/transport documentation.

**Breaking preview type identity:** the existing 2.0-preview server
lookup `Opc.Ua.ISessionBindingProvider` becomes
`Opc.Ua.IServerSessionBindingProvider`. Server lookup consumers must
update their referenced type and rebuild. This is neither
source-compatible nor binary-additive for that preview type. The new
client capability is optional and adds no mandatory members to existing
ISession/ISessionClient/ITransportChannel contracts. This
preview-to-preview rename is documented in SessionBindings/Transports,
not in the 1.5-to-2.0 MigrationGuide.

**Ownership boundary:** no RequestLifetime changes,
certificate-manager/channel-entry adoption, BaseVariableState changes,
Method-result feature extraction, NodeManager batch/readiness or
browse-history retention, session restoration, registry federation, WoT
conversion, or WoT runtime/planners/events.
DependencyInjection/ResourceIsolation/index changes are lookup/link
closure only. SessionManager's PR hunk changes only its implemented
lookup-interface name; newer master public diagnostic masking is not
replaced.

### Review qualification

Review fixes are published at
**`6b0eb1d5c32a439300fbcaff974b9af8b909161b`**, changing eight
already-owned files. All five received review threads were replied to
and resolved after verification. Factory selector installation and
target-selection-plus-commit share the root publication gate, with
consistent root→image release/capture ordering. TypeTable selector
installation and final mutation routing share its existing gate. Native
bound channel validity uses volatile observations; the two owned XML
defects are corrected.

| Requirement | Evidence |
|---|---|
| Selector installation must not hide TypeTable mutations |
`SelectorInstalledDuringNodePreparationReceivesMutation`: old Add
routing failed on both TFMs; corrected routing passes on both within
**148/148** factory/TypeTable controls |
| Selector installation must not race factory commit routing | Static
common-root-gate/order proof plus baseline-GREEN
`BuilderCapturedBeforeOwnershipUsesSelectedFactory`,
`ViewOwnerReleasePreservesRegistrationsAndAllowsReuse`,
`ViewOwnerReleaseCanRetryAfterPendingPublication`,
`PublicationProtectsPendingAndRetiredFactoryImages` |
| Lock-free validity must observe owner transitions | Static
volatile-read reasoning plus native
`BoundRequestCannotDispatchWhileNativeReplacementIsPendingAsync`,
`BoundResponseRejectsInvalidationAfterNativeDispatchAsync`,
`BoundClientCannotRetryAcrossFaultedManagedEntryReplacementAsync`:
**12/12 each TFM**; Core binding/pooled ownership controls **17/17 each
TFM** |
| Correct owned XML documentation | “an unmanaged” and one multiline
`ReferenceUpdate.Next` summary; scoped whitespace/INFO and build
evidence below |

Factory controls are **not** claimed as a deterministic factory RED, and
public transport controls are **not** claimed as a deterministic
weak-memory RED. No private-lock reflection, artificial production seam,
or source-name assertion was added. The TypeTable RED uses the real
`ILocalNode.NodeClass` callback during node preparation, and both
expected RED receipts/TRX were retained.

All accepted review runs use the unchanged admitted SDK wrapper, normal
project references, sole mutex, one node/no shared compiler, finite
resource guards and canonical short-C build outputs. Source hashes were
frozen per command and matched the committed bytes afterward. SDK
ownership was released **before** commit/push/review replies. No
automatic merge was requested.

Scoped whitespace passed across the four affected projects. Review INFO
classification is **0 owned findings / 13 untouched baseline findings
excluded** (whole-file formatter exits 1,1,0,0); no baseline
RCS1140/RCS0055 expansion or suppression. The final normal net10 public
Client/Core/Types trim/AOT-analyzer closure passed **0 warnings / 0
errors**. This is not a NativeAOT publish/run.

<summary>Accepted review command payloads and results</summary>

These exact argument payloads were executed through the unchanged
guarded SDK wrapper. `$proof` expands to the protected results-directory
below. Successful explicit builds of the same source preceded the
`--no-build` runs.

```powershell
$proof = 'C:\Users\mschier\.copilot\session-state\a3b74048-c52f-4c87-8773-7a46c9ab0087\files\qualification-review-4752'

The six expanded GREEN commands, exact results/TRX hashes and two
expected RED commands are retained in
`qualification-review-4752\qualification-summary.json`, SHA256
`C5E71A4D8D37BAC8803F6DF38B6BCE2B70F3D0AFD5DEC8493FAE9DB440DCFB5A`.
Committed/qualified byte identity is in `publication-identity.json`,
SHA256
`CD9515FE96703F8B241F2B7B9B71F73EF0FF2626C2C8BCCE40307971A8F8E809`.
Per-command raw exits, guards, hashes and reports are retained outside
disposable build roots.

For each record in the protected `format-inputs.json` (Types/Core/Client
libraries and Types.Tests), the recorded Project/Include values expand
these exact payloads:

```powershell
# Workspace properties recorded with the formatter receipts:
$env:CustomTestTarget = 'net10.0'
$env:UseArtifactsOutput = 'true'
$env:ArtifactsPath = 'C:\cp56-a3b7-v2'

# All four exit 0
dotnet format whitespace $Project --no-restore --verify-no-changes --verbosity minimal --include $Include

# Exits 1,1,0,0 due only to untouched baseline findings; owned=0, baseline=13
dotnet format $Project --no-restore --severity info --verify-no-changes --verbosity minimal --report "$proof\formats\review-info-$i" --include $Include
```

Initial fresh matrix evidence remains separately identified and
unchanged: Types274/Core119/Client151/server137 net10;
Types274/Core119/Client151/server135 net48, all passing. Qualification
base remains `0dff94bd378e79b8cf1a47e1aaf340f9b4b40048`; the initial
published head was `9fee4583`. All 16 initial exact command
arrays/results/TRX hashes remain in protected
`qualification-v2\qualification-summary.json`, SHA256
`88E10240C20049B59A3401BE007C6528A85DF2F3DCFAF9D11D908CEF2946DA4E`.

Failures/incidents remain retained rather than relabeled as success:
original disappeared-root historical counts are invalidated; the
large-TRX controller DOM-parser failure is preserved separately from
accepted streaming receipts; the review argument-array
defect/default-D-output controls are preserved but excluded from
canonical review qualification. Correctly separated argument rechecks
produced the accepted short-C Core/Client receipts. The sole SDK wrapper
was not changed.

Full UA.slnx, measured coverage increase, CLA verification, NativeAOT
publication and current-head/master CI/CodeQL remain unclaimed. Actual
merge—not resolved review threads—unlocks Wave B.
