Add configurable server resource isolation (#4541)
# Description Add configurable server resource isolation on top of the merged #4522 foundation. - Coordinate connection, handshake, retained-message, session-establishment, queue, execution, request-cost and parked-request limits through one server-scoped provider. - Keep configured startup, continuity/reconnect, control and trusted-owner reservations inside existing totals. Shared capacity remains usable up to explicit owner ceilings. - Use authoritative Session membership for reassembly continuity capacity without granting unrelated resource or rate privileges. Preserve explicit owner mappings and bounded tracking. - Cache immutable classification evidence while retaining current Session and classifier checks. - Support weighted request ordering or FIFO independently of resource accounting. Installed providers enforce decoded-request limits in both modes. - Preserve fail-fast reassembly, valid Abort handling, fixed deadlines, active-work protection, reverse-connect handoff and bounded OpenAPI processing. - Support custom-handler parking through `IRequestParkingPolicy`, `WithRequestParking(...)`, and `RequestLifetime.ParkSink`. Parking releases execution capacity only, keeping retained-data and parked charges until completion. Built-in Publish and the global opt-out remain unchanged. - Provide direct, fluent and DI configuration, public incoming-request parking support, effective startup limit logs and user-facing documentation. Balanced remains the default. SharedOnly without an explicit provider retains shared behavior for intentionally incompatible/unlimited configurations. Reservations are finite and are not one full-message allowance per Session. ## Related Issues Builds on merged #4522. Fixes #4554. ## Review and CI corrections All three previously missed findings in [review 5326734718](https://github.com/OPCFoundation/UA-.NETStandard/pull/4541#pullrequestreview-5326734718) are addressed in `9e25e4ecc`: 1. A custom FIFO provider receives RequestQueue, RequestQueueBytes, RequestExecution and ParkedRequest accounting. A blocked head cannot be overtaken. 2. `IResourceIsolationReassemblyProvider` replaces the sessionless threshold independently of `UseFairScheduling`. The aggregate byte ceiling remains enforced. 3. Runtime `ReservedReassemblyBytes` includes all configured protected stage floors, including ControlReserved. The review's two already-resolved changes remain intact. The CI collection race was fixed at its source in `e1a994a4b`: `ArrayOf.ToArrayOf` treats a separately read collection count as an initial capacity hint and grows/trims for the actual enumeration. Deterministic tests cover growth, shrinkage and stale-zero counts. The subsequent recovery-test race was fixed in `05753ce77`: fake time advances only after a gated keepalive response has been processed and reset its timer, not merely after request arrival. Recovery-order and timeout assertions remain intact, with additional response-state assertions. Instrumentation reproduced the original failure twice; both fixed variants passed 400 executions per framework. CodeQL alert 388 was verified and dismissed as a false positive. Startup logs contain aggregate numeric capacities, not credentials or caller identities. ## Validation | Scope | Result | | --- | --- | | Latest automated checks at `05753ce7775a58801b4ba9d8f6d7781b709d0b89` | 167 successful, one package-publication check skipped, no failures | | Remaining external prerequisite | `license/cla` pending: Contributor License Agreement is not signed yet | | FIFO/weighted queues, custom parking and server-channel selection | 175 passed on each net10.0/net48 | | Isolation, configuration and parking-hosting selection | 259 passed net10.0; 257 passed net48 | | ArrayOf conversion tests | 73 passed on each net10.0/net48 | | Recovery-audit and keepalive fixtures | 40 passed on each net10.0/net48 | | NativeAOT smoke from preceding updates | Published and executed successfully | No tests, assertions, coverage thresholds, or required checks were weakened.

Fix incomplete-message buffering and channel cleanup (#4522)
# Description Fix incomplete-message buffering, channel cleanup, session resource accounting, and enforcement of existing transport admission settings. - Share a targeted `ChunkReassemblyBudget` across server listeners. The reference default is 64 MiB, with a 32 MiB global occupancy threshold for sessionless intermediate chunks. This is priority headroom for activated sessions, not a guaranteed bootstrap partition. Single/final chunks and unrelated response/client buffers remain outside this budget. - Retain precise incoming/final payload quotas, valid Abort handling without channel teardown, terminal late-final rejection, and exactly-once buffer/reservation cleanup. - Use one assembly timer per quota/clock scope, asynchronous cleanup, a fixed deadline, a 30-second fallback for non-positive lifetimes, and best-effort ERR `BadTimeout` before closure. - Apply negotiated TCP/WebSocket/Pipe receive limits and size pipe rentals to actual chunks. - Add the optional `ISessionBindingProvider` and immutable `SessionBindingContext` seam. Managed membership counts distinct committed sessions, not responses, and handles reactivation, transfer, closure, expiry, restoration and shutdown. Read-only snapshots require token/channel/security validation and never replace service authorization. - Wire default and explicitly injected binding providers through raw TCP, Kestrel and UACP WebSockets; preserve existing callback/manager interfaces and direct construction. - Enforce existing `ConnectionRateLimiter` and channel capacity settings on Kestrel TCP and UACP WebSocket admission, with physical-transport leases surviving reverse handoff and releasing on cancellation, close, failed attachment and stop. HTTP/JSON requests are not treated as UASC channels. - Add regression coverage and documentation. Stabilize the CI cancellation test by waiting for the resolver to enter before canceling. This is the foundation only. New Balanced/FairShare/TrustedReservations policies, tenant isolation and guaranteed bootstrap reserves belong in the separate stacked follow-up, not this PR. ## Related Issues Fixes #4521. ## Validation | Scope | Result | | --- | --- | | Core transport, budget, binding-context and DI tests, net10.0 | 717 passed | | Core transport, budget, binding-context and DI tests, net48 | 664 passed, 6 platform-specific skips | | Session bindings, transfer/security/expiry/restore and hosted DI, net10.0 | 69 passed | | Same focused Server suite, net48 | 69 passed | | ServerRedundancyHandlerTests, Release/net48 | 39 passed | | ConsoleReferenceServer net10.0 | Build succeeded, zero warnings/errors | | Server and HTTPS binding netstandard2.1 | Both builds succeeded, zero warnings/errors | The new admission fixtures also passed five repeated runs after correcting asynchronous connection-context disposal. Full-solution validation, coverage comparison and CI for this update remain pending. ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [ ] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. |
