+# MXAccess Gateway Agent Guide
+
+Repository: https://gitea.dohertylan.com/dohertj2/mxaccessgw
+
+This project builds a gateway that gives modern clients full MXAccess parity
+without requiring those clients to load MXAccess COM, run as x86, or own an STA
+message pump. Treat the installed MXAccess COM component as the compatibility
+baseline.
+
+Toolchain paths, versions, and external analysis locations are recorded in
+`docs/toolchain-links.md`. Use that file before searching for compilers,
+runtimes, protobuf tools, MXAccess notes, or Galaxy Repository SQL notes.
+
+Implementation planning is recorded in `docs/implementation-plan-index.md`.
+Follow the order there unless the user explicitly reprioritizes: gateway first,
+MXAccess worker instance second, clients third.
+
+## Core Contract
+
+Preserve MXAccess behavior first:
+
+- public MXAccess command semantics,
+- native MXAccess event families,
+- STA/message-pump delivery behavior,
+- installed-provider quirks,
+- HRESULT/status/value marshaling,
+- per-client isolation.
+
+Do not simplify, normalize, or "fix" MXAccess behavior unless an explicit
+non-parity mode is being implemented and tested. `MxAsbClient` and managed NMX
+are future acceleration paths only; they do not define the parity contract.
+
+## Architecture
+
+The intended split is:
+
+```text
+client
+  -> gRPC over TCP
+    -> .NET 10 x64 gateway
+      -> session manager
+        -> per-session .NET Framework 4.8 x86 worker process
+          -> dedicated STA thread
+            -> MXAccess COM instance
+            -> Windows/COM message pump
+            -> command queue
+            -> event sink
+```
+
+The gateway must never instantiate or call MXAccess directly. All MXAccess COM
+interaction belongs in the worker process on its dedicated STA thread.
+
+The worker must not host public gRPC. Gateway-to-worker communication should use
+a small local IPC protocol, with named pipes and protobuf-framed messages as the
+default design.
+
+## Runtime Targets
+
+- Gateway: .NET 10, C#, x64 preferred, ASP.NET Core gRPC.
+- Worker: .NET Framework 4.8, C#, x86 by default.
+- Worker IPC: one bidirectional named pipe per worker.
+- Worker process model: one external client session maps to one worker by
+  default.
+
+## Style Guides
+
+Follow the project documentation guide and the language guide for every changed
+area:
+
+| Area | Style guide |
+|------|-------------|
+| Documentation | `StyleGuide.md` |
+| Gateway, worker, .NET client, and C# tests | `docs/style-guides/CSharpStyleGuide.md` |
+| Public gRPC and worker IPC contracts | `docs/style-guides/ProtobufStyleGuide.md` |
+| Go client | `docs/style-guides/GoStyleGuide.md` |
+| Rust client | `docs/style-guides/RustStyleGuide.md` |
+| Python client | `docs/style-guides/PythonStyleGuide.md` |
+| Java client | `docs/style-guides/JavaStyleGuide.md` |
+
+When a change crosses languages, apply every affected style guide. Generated
+code follows its generator output; do not hand-edit it to match handwritten
+style.
+
+## Expected Layout
+
+Prefer this structure unless there is a strong reason to adjust it:

+
+clients/java/
+  Java client library, test CLI, and tests
+```
+
+The contracts project may multi-target, or the `.proto` files may be shared as
+source inputs to both gateway and worker builds.
+
+## Public API Shape
+
+The external API should be session-oriented. Initial rollout should prefer
+unary `OpenSession`, `CloseSession`, and `Invoke`, plus server-streaming
+`StreamEvents`. Add a bidirectional `Session` stream after the command and event
+model is stable.
+
+Do not compress MXAccess into generic verbs too early. Use a command enum with
+method-specific payloads so parity can be tested method by method.
+
+Core MXAccess commands to represent:
+
+- `Register`
+- `Unregister`
+- `AddItem`
+- `AddItem2`
+- `RemoveItem`
+- `Advise`
+- `UnAdvise`
+- `AdviseSupervisory`
+- `AddBufferedItem`
+- `SetBufferedUpdateInterval`
+- `Suspend`
+- `Activate`
+- `Write`
+- `Write2`
+- `WriteSecured`
+- `WriteSecured2`
+- `AuthenticateUser`
+- `ArchestrAUserToId`
+
+Diagnostics may include `Ping`, `GetSessionState`, `GetWorkerInfo`,
+`DrainEvents`, and `ShutdownWorker`.
+
+## Event Requirements
+
+Represent every public MXAccess event family:
+
+- `OnDataChange`
+- `OnWriteComplete`
+- `OperationComplete`
+- `OnBufferedDataChange`
+
+Preserve per-worker event order. The gateway must not reorder events emitted by
+the same MXAccess instance.
+
+Event DTOs should carry event family, session id, server handle, item handle,
+value, quality, timestamp, `MXSTATUS_PROXY[]` equivalent, raw HRESULT/status
+fields when available, event sequence, worker timestamp, and gateway receive
+timestamp.
+
+## Value And Status Rules
+
+Use a protobuf value union that can represent COM `VARIANT` values and arrays.
+When a value cannot be losslessly converted, preserve both the best typed
+projection and enough raw diagnostic metadata to reproduce the case.
+
+Represent `MXSTATUS_PROXY` explicitly. Do not collapse status arrays into a
+single success flag.
+
+Command replies should include protocol status, COM HRESULT if available,
+MXAccess return values, method-specific out parameters, and status arrays where
+the MXAccess method emits them.
+
+## Galaxy Repository SQL Discovery
+
+Galaxy tags, hierarchy, and attribute details can be queried from the AVEVA /
+Wonderware System Platform Galaxy Repository SQL Server database. Use this as a
+discovery and metadata path only; runtime MXAccess parity still belongs to the
+MXAccess-backed worker unless an explicit non-parity backend is being designed.
+
+Full notes, schema details, screenshots, and query examples are in:
+
+```text
+C:\Users\dohertj2\Desktop\lmxopcua\gr
+```
+
+Important files in that notes directory:
+
+- `connectioninfo.md` - SQL Server connection details and `sqlcmd` usage.
+- `layout.md` - hierarchy vs `tag_name` relationship.
+- `build_layout_plan.md` - extraction plan for hierarchy and attributes.
+- `schema.md` and `ddl/` - Galaxy Repository schema reference.
+- `queries/hierarchy.sql` - deployed object hierarchy.
+- `queries/attributes.sql` - user-defined dynamic attributes.
+- `queries/attributes_extended.sql` - system plus user-defined attributes.
+- `queries/change_detection.sql` - deployment-change polling via
+  `galaxy.time_of_last_deploy`.
+
+Current documented connection is SQL Server `localhost`, database `ZB`, Windows
+Auth. Example:
+
+```powershell
+sqlcmd -S localhost -d ZB -E -Q "SELECT time_of_last_deploy FROM galaxy;"
+```
+
+Key tables from the notes are `gobject`, `template_definition`,
+`dynamic_attribute`, `attribute_definition`, `primitive_instance`, and
+`galaxy`. The hierarchy uses contained names for human-readable browsing, while
+runtime tag references use globally unique `tag_name` values such as
+`<tag_name>.<AttributeName>`.
+
+## MXAccess Analysis Source
+
+Use the local MXAccess analysis project when answering questions about installed
+MXAccess classes, interfaces, fields, events, HRESULT/status behavior, value
+projection, captures, and parity gaps:
+
+```text
+C:\Users\dohertj2\Desktop\mxaccess
+```
+
+Primary files:
+
+- `README.md` - overview of available analysis and capture artifacts.
+- `docs/MXAccess-Public-API.md` - COM class, ProgID, CLSID, method list,
+  event signatures, `MxDataType`, `MxStatus`, and `MXSTATUS_PROXY`.
+- `docs/MXAccess-Reverse-Engineering.md` - installed runtime path and x86 COM
+  constraints.
+- `docs/Current-Sprint-State.md` and `docs/DotNet10-Native-Library-Plan.md` -
+  current parity gaps and managed native-client research status.
+- `src/MxTraceHarness/` - x86 MXAccess harness examples using the real COM
+  interop assembly.
+- `captures/` and `analysis/` - observed native behavior and generated
+  reverse-engineering artifacts.
+
+Concrete MXAccess COM target from the analysis:
+
+- class: `ArchestrA.MxAccess.LMXProxyServerClass`
+- CLSID: `{C30B52F5-2CB5-4760-AF0A-3A344A7EB5DC}`
+- ProgID: `LMXProxy.LMXProxyServer.1`
+- version-independent ProgID: `LMXProxy.LMXProxyServer`
+- registered server: `C:\Program Files (x86)\ArchestrA\Framework\Bin\LmxProxy.dll`
+- interop assembly:
+  `C:\Program Files (x86)\ArchestrA\Framework\Bin\ArchestrA.MXAccess.dll`
+- threading model: `Apartment`
+
+## Worker Rules
+
+Each worker owns:
+
+- one process,
+- one MXAccess session,
+- one dedicated STA thread,
+- one MXAccess COM object,
+- one inbound command queue,
+- one outbound event queue.
+
+All MXAccess operations must run on the STA. A plain blocking queue is not
+enough for the STA; the STA loop must pump Windows/COM messages and service
+queued commands.
+
+Do not block the STA on pipe writes, gRPC calls, or slow consumers. Event
+handlers should convert event args, enqueue outbound events, and return to
+pumping messages.
+
+On graceful shutdown, reject new commands, optionally clean up active MXAccess
+handles, detach events, release the COM object, uninitialize COM, and exit. If
+graceful shutdown exceeds the configured timeout, the gateway may kill the
+worker.
+
+## IPC Rules
+
+Default pipe name shape:
+
+```text
+mxaccess-gateway-{gatewayProcessId}-{sessionId}
+```
+
+Frame messages as:
+
+```text
+uint32 little-endian payload_length
+payload_length bytes protobuf WorkerEnvelope
+```
+
+Every envelope should include protocol version, session id, monotonic sender
+sequence, correlation id, and a typed body. Protocol version mismatch should
+fail session creation.
+
+Pipe security should be local-machine only, with ACLs restricted to the gateway
+identity and launched worker identity. Prefer a per-session nonce handshake.
+
+## Gateway Rules
+
+The gateway is responsible for:
+
+- public TCP/gRPC API,
+- Blazor Server dashboard using Bootstrap CSS/JS only,
+- authn/authz when needed,
+- session creation and teardown,
+- worker launch and lifecycle management,
+- command routing,
+- event streaming,
+- leases, heartbeats, timeouts, and quotas,
+- worker kill/restart policy,
+- metrics and structured logs.
+
+The gRPC layer should stay thin: validate request, find session, call the
+session worker client, map worker replies to public replies, and stream events.
+Keep MXAccess-specific translation logic testable outside the gRPC handlers.
+
+Dashboard code should also stay thin and read-only for v1. Use a snapshot
+service over session/worker/metrics state; do not let Razor components mutate
+gateway sessions or workers directly. Do not use MudBlazor or other Blazor UI
+component libraries.
+
+Gateway restart should not try to reattach old workers in the first version.
+Terminate orphaned workers on startup if that behavior is implemented.
+
+## Command, Timeout, And Cancellation Semantics
+
+Command lifecycle:
+
+```text
+client gRPC command
+gateway validates session and payload
+gateway assigns correlation id
+gateway writes WorkerCommand to pipe
+worker queues command to STA
+STA executes MXAccess method
+worker captures return/out/status/HRESULT
+worker sends WorkerCommandReply
+gateway completes gRPC response
+```
+
+Canceling a gRPC call should stop waiting in the gateway, but it cannot safely
+abort an in-flight COM call on the STA. Hard cancellation means killing the
+worker process.
+
+If a command wedges the STA beyond a configured grace period, the gateway should
+kill the worker and fail the session.
+
+## Backpressure Policy
+
+Worker outbound events must use a bounded queue. For parity testing, prefer
+fail-fast behavior over silent drops. Production coalescing or drop policies
+must be explicit and observable.
+
+The gateway should preserve per-session event order, apply backpressure from
+slow gRPC streams, and disconnect or coalesce only according to an explicit
+policy.
+
+## Security And Logging
+
+Use TLS for remote gRPC when crossing machine boundaries. Authentication may be
+Windows auth, mTLS, or a deployment-specific token.
+
+Commands that write, authenticate users, or alter runtime state need explicit
+authorization design.
+
+Never log passwords or raw credential values for `AuthenticateUser`,
+`WriteSecured`, or related secured operations. Do not log full values by
+default; make value logging opt-in and redacted.
+
+## Testing Expectations
+
+Use focused tests for:
+
+- contract/protobuf compatibility,
+- gateway session state and worker lifecycle,
+- gateway behavior with a fake worker,
+- worker value/status conversion,
+- STA queue and message-pump behavior.
+
+Live MXAccess integration tests are optional but should be isolated because they
+depend on installed COM components and provider behavior.
+
+Parity tests should compare direct MXAccess behavior against the gateway:
+
+- return values,
+- HRESULTs and exceptions,
+- event sequence,
+- value projection,
+- quality/status arrays,
+- invalid handle behavior,
+- cross-server handle behavior,
+- cleanup behavior.
+
+Known important parity areas:
+
+- `WriteSecured` may fail before a value-bearing NMX body is emitted.
+- `WriteSecured2` can succeed in observed native paths.
+- `OperationComplete` is distinct from write completion.
+- `OnBufferedDataChange` has a distinct public event shape.
+- Invalid handles and cross-server handles have specific exception/status
+  behavior.
+- STA message pumping is required for event delivery.
+
+## Source Update Workflow
+
+When source code changes, build the affected component before handing work
+back. If the change crosses component boundaries, build each affected component
+instead of relying on a single top-level build.
+
+Use the native build and test command for each changed area:
+
+| Changed area | Required verification |
+|--------------|-----------------------|
+| Contracts or `.proto` files | regenerate generated code, then build gateway, worker, and every generated client touched by the contract |
+| Gateway server, sessions, workers, gRPC, dashboard, or metrics | build the .NET 10 gateway project and run affected gateway or fake-worker tests |
+| Worker IPC, STA, MXAccess, or conversion code | build the .NET Framework 4.8 x86 worker project and run affected worker tests |
+| Shared test infrastructure | run every test suite that consumes the changed helpers |
+| .NET client | build the .NET client library, CLI, and tests |
+| Go client | run Go formatting, build, and tests for the Go module |
+| Rust client | run Rust formatting, build or check, and tests for the Rust crate |
+| Python client | run Python formatting or linting if configured, package/build checks, and tests |
+| Java client | build the Java client library, CLI, and tests |
+| Integration tests | run them only when the required MXAccess COM component, provider state, and external services are available; otherwise document why they were skipped |
+
+Update affected documentation in the same change as the source update. This
+includes `gateway.md`, component design docs under `docs/`, client docs, API
+contract notes, test instructions, and operational guidance. Documentation must
+follow `StyleGuide.md`: write technical present-tense prose, explain the reason
+for non-obvious choices, use exact code names, specify languages on code
+blocks, use relative links for internal docs, and avoid stale temporary notes.
+Source code and contract changes must also follow the relevant language guide
+from the Style Guides section.
+
+Do not leave documentation describing old behavior after changing public APIs,
+contracts, configuration, build steps, security behavior, event shapes, value
+conversion, status mapping, lifecycle rules, or client semantics.
+
+## Implementation Priority
+
+Build the smallest end-to-end slice first:
+
+1. .NET 10 gateway starts.
+2. Client calls `OpenSession`.
+3. Gateway launches .NET Framework 4.8 x86 worker.
+4. Worker creates STA and MXAccess COM object.
+5. Client calls `Register`.
+6. Client calls `AddItem`.
+7. Client calls `Advise`.
+8. Worker forwards one `OnDataChange` event to the gateway.
+9. Gateway streams the event to the client.
+10. Client calls `CloseSession`.
+11. Gateway shuts down the worker.
+
+That slice proves the high-risk requirements: process isolation, STA ownership,
+message pumping, command routing, and event streaming.

-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-
-`mxaccessgw` is the MXAccess Gateway: a gRPC service that gives modern (.NET, Go, Rust, Python, Java) clients full MXAccess parity without forcing them to load 32-bit MXAccess COM, run x86, or own an STA message pump.
-
-The architecture is a two-process design — read `gateway.md` before making structural changes:
-
-- **Gateway** (`src/MxGateway.Server`, .NET 10, x64): ASP.NET Core gRPC server. Owns the public API, sessions, auth, the Blazor dashboard, and the Galaxy Repository SQL browse RPCs. **Never instantiates MXAccess COM directly.**
-- **Worker** (`src/MxGateway.Worker`, .NET Framework 4.8, **x86**): one process per session. Owns one MXAccess COM instance on a dedicated STA, pumps Windows messages, and converts COM events to protobuf.
-- **IPC**: gateway↔worker uses one bidirectional named pipe per worker (`mxaccess-gateway-{gatewayPid}-{sessionId}`) with length-prefixed `WorkerEnvelope` protobuf frames. Gateway hosts the pipe server and launches the worker. **gRPC is not used inside the worker** — .NET Framework 4.8 doesn't have a first-class gRPC stack.
-- **Contracts** (`src/MxGateway.Contracts`): multi-targets `net10.0;net48` and owns the `.proto` files (`mxaccess_gateway.proto`, `mxaccess_worker.proto`, `galaxy_repository.proto`). All other projects consume the generated types from here. Do not hand-edit anything under `Generated/`.
-
-The worker must do all MXAccess COM calls on its dedicated STA thread, and the STA loop must pump Windows messages (`MsgWaitForMultipleObjectsEx` + `PeekMessage`/`DispatchMessage`) so MXAccess events deliver. A plain blocking queue on an STA is not enough.
-
-## Build, Test, Run
-
-```powershell
-# Full solution build (gateway, worker, contracts, tests)
-dotnet build src/MxGateway.sln
-
-# Worker must be built x86 — the gateway looks for MxGateway.Worker.exe under bin\x86
-dotnet build src/MxGateway.Worker/MxGateway.Worker.csproj -p:Platform=x86
-
-# Gateway tests (no MXAccess required — uses FakeWorkerHarness)
-dotnet test src/MxGateway.Tests/MxGateway.Tests.csproj
-dotnet test src/MxGateway.Worker.Tests/MxGateway.Worker.Tests.csproj -p:Platform=x86
-
-# Run gateway locally (defaults bound under MxGateway:* in src/MxGateway.Server/appsettings.json)
-dotnet run --project src/MxGateway.Server/MxGateway.Server.csproj
-
-# API-key admin CLI (same exe, "apikey" subcommand)
-dotnet run --project src/MxGateway.Server/MxGateway.Server.csproj -- apikey create --display-name "dev" --scopes session,invoke,event,metadata,admin
-```
-
-Single test by name (xUnit `--filter`):
-
-```powershell
-dotnet test src/MxGateway.Tests/MxGateway.Tests.csproj --filter FullyQualifiedName~GatewayEndToEndFakeWorkerSmokeTests
-```
-
-Live MXAccess integration tests are **opt-in** because they need installed MXAccess COM and live provider state:
-
-```powershell
-$env:MXGATEWAY_RUN_LIVE_MXACCESS_TESTS = "1"
-dotnet test src/MxGateway.IntegrationTests/MxGateway.IntegrationTests.csproj --filter FullyQualifiedName~WorkerLiveMxAccessSmokeTests
-```
-
-Live LDAP tests use `MXGATEWAY_RUN_LIVE_LDAP_TESTS=1`. See `docs/GatewayTesting.md` for the full opt-in matrix and `LiveMxAccessFactAttribute` / `LiveLdapFactAttribute` for the gating logic.
-
-## Clients
-
-Each language client is in `clients/<lang>/` with its own README. They all consume the shared `.proto` files in `src/MxGateway.Contracts/Protos`:
-
-- `clients/dotnet`: `dotnet build clients/dotnet/MxGateway.Client.sln`
-- `clients/python`: `python -m pip install -e ".[dev]"; python -m pytest`
-- `clients/rust`: `cargo test --workspace; cargo clippy --workspace --all-targets -- -D warnings`
-- `clients/java`: `gradle test` (Java 21)
-- Go client lives alongside as `mxgw-go` in the cross-language matrix
-
-End-to-end matrix runner (needs running gateway + worker + valid API key):
-
-```powershell
-$env:MXGATEWAY_API_KEY = "<api-key>"
-powershell -ExecutionPolicy Bypass -File scripts/run-client-e2e-tests.ps1
-```
-
-## Repository-Specific Conventions
-
-- **Build properties** (`src/Directory.Build.props`) enforce `Nullable=enable`, `TreatWarningsAsErrors=true`, latest analyzers, and `EnforceCodeStyleInBuild=true`. New warnings break the build — fix them, don't suppress unless the suppression has a narrow reason.
-- **Style guides** in `docs/style-guides/` are authoritative. Follow `CSharpStyleGuide.md` for gateway/worker/.NET-client code: file-scoped namespaces, `sealed` by default, `Async` suffix on Task-returning methods, MXAccess-aligned names (`MxStatusProxy`, `ServerHandle`, `ItemHandle`, `HResult`).
-- **MXAccess parity is the contract.** Don't "fix" surprising MXAccess behavior (e.g., `WriteSecured` failing before a value-bearing NMX body, distinct `OperationComplete` semantics, invalid-handle exceptions) unless the client explicitly opts into a non-parity mode. The installed MXAccess COM component is the baseline.
-- **Don't synthesize events.** The gateway forwards only events the worker emits; it never invents `OperationComplete` from write completion or command replies.
-- **One worker per session, one event subscriber per session** (v1). Multi-subscriber fan-out and reconnectable sessions are explicitly out of scope — see `docs/DesignDecisions.md`.
-- **Gateway restart does not reattach orphan workers.** The first version terminates orphaned workers on startup; do not design code paths that assume reattachment.
-- **No Blazor UI component libraries.** Dashboard uses local Bootstrap CSS/JS only — do not introduce MudBlazor, Radzen, FluentUI, etc.
-- **Don't log secrets or full tag values by default.** API keys, passwords, `WriteSecured` payloads, and `AuthenticateUser` credentials must never reach logs. Value logging is opt-in and redacted.
-- **Generated code** under `src/MxGateway.Contracts/Generated/`, `clients/*/generated*/`, `clients/python/src/mxgateway/generated/`, etc., is build output. Don't hand-edit. To regenerate, build the contracts project (`dotnet build src/MxGateway.Contracts/MxGateway.Contracts.csproj`) or run the per-client generation step in that client's README.
-- **Documentation style** (`StyleGuide.md`): PascalCase filenames, no marketing language, present tense, explain *why* not *what*.
-- **Update docs in the same change as the source.** When public APIs, contracts, configuration, build steps, security behavior, event shapes, value conversion, status mapping, or lifecycle rules change, the affected docs (`gateway.md`, `docs/`, client READMEs, design docs) must change in the same commit. Don't leave stale prose describing old behavior.

-## Source Update Workflow
-
-When source code changes, build and test the affected component before reporting work done. If the change crosses component boundaries, build each affected component — don't rely on a single top-level build:
-
-| Changed area | Required verification |
-|---|---|
-| Contracts or `.proto` files | regenerate generated code, then build gateway, worker, and every generated client touched by the contract |
-| Gateway server, sessions, workers, gRPC, dashboard, metrics | `dotnet build src/MxGateway.Server` and run affected gateway / fake-worker tests |
-| Worker IPC, STA, MXAccess, conversion | `dotnet build src/MxGateway.Worker -p:Platform=x86` and run worker tests |
-| .NET client | `dotnet build clients/dotnet/MxGateway.Client.sln` and run its tests |
-| Go client | `gofmt`, `go build ./...`, `go test ./...` from `clients/go` |
-| Rust client | `cargo fmt`, `cargo check --workspace`, `cargo test --workspace`, `cargo clippy --all-targets -- -D warnings` from `clients/rust` |
-| Python client | `python -m pytest` from `clients/python` |
-| Java client | `gradle test` from `clients/java` |
-| Integration tests | run only when MXAccess COM, provider state, and external services are available; otherwise document why skipped |

-## Design Sources To Consult Before Non-Trivial Changes
-
-- `gateway.md` — top-level architecture, command/event surface, IPC envelope, STA thread model, fault handling.
-- `glauth.md` — local LDAP server (GLAuth on `localhost:3893`, base DN `dc=lmxopcua,dc=local`) used for dev authn. Pre-provisioned users (`admin/admin123`, `readonly/readonly123`, etc.) and the role→capability mapping live there.
-- `docs/DesignDecisions.md` — v1 choices (MXAccess COM target `LMXProxyServerClass` from `C:\Program Files (x86)\ArchestrA\Framework\Bin\ArchestrA.MXAccess.dll`, API-key-in-SQLite auth, fail-fast event backpressure, etc.).
-- `docs/GatewayProcessDesign.md`, `docs/MxAccessWorkerInstanceDesign.md`, `docs/WorkerFrameProtocol.md`, `docs/WorkerProcessLauncher.md` — detailed component designs.
-- `docs/GatewayConfiguration.md` — full `MxGateway:*` options bound by `GatewayOptions` and validated at startup by `GatewayOptionsValidator`.
-- `docs/GatewayTesting.md` — fake worker harness, live MXAccess smoke, parity matrix, cross-language smoke matrix.
-- `docs/ToolchainLinks.md` — installed compiler/SDK paths on this dev box (.NET 10.0.201, Go 1.26.2, Rust 1.95, Python 3.12.10, Temurin 21, protoc 34.1, etc.).
-
-External analysis sources referenced by design docs:
-
-- `C:\Users\dohertj2\Desktop\mxaccess` — MXAccess analysis project. Key files: `docs/MXAccess-Public-API.md` (COM class, ProgID, CLSID, method list, event signatures, `MxDataType`, `MxStatus`, `MXSTATUS_PROXY`), `docs/MXAccess-Reverse-Engineering.md` (installed runtime path, x86 COM constraints), `docs/Current-Sprint-State.md` (parity gaps), `src/MxTraceHarness/` (x86 harness using the real COM interop), `captures/` and `analysis/` (observed native behavior).
-- `C:\Users\dohertj2\Desktop\lmxopcua\gr` — Galaxy Repository (`ZB` SQL DB) notes. Key files: `connectioninfo.md`, `layout.md`, `schema.md`, `queries/hierarchy.sql`, `queries/attributes.sql`, `queries/attributes_extended.sql`, `queries/change_detection.sql`. Connection is SQL Server `localhost`, database `ZB`, Windows Auth.
-
-## Authentication
-
-Gateway gRPC clients authenticate with an API key in metadata: `authorization: Bearer mxgw_<key-id>_<secret>`. Keys are stored hashed (with a peppered SHA) in a gateway-owned SQLite DB (default `C:\ProgramData\MxGateway\gateway-auth.db`). Scopes (`session`, `invoke`, `event`, `metadata`, `admin`) gate specific RPCs; missing → `Unauthenticated`, insufficient → `PermissionDenied`. The `apikey` subcommand on the server exe manages keys; see `src/MxGateway.Server/Security/Authentication/`.

-Dashboard auth is LDAP-backed (separate from the gRPC API-key model). `/login` binds against `MxGateway:Ldap` and maps the user's LDAP groups to `Admin` or `Viewer` via `MxGateway:Dashboard:GroupToRole`, then issues an HTTP-only secure `__Host-MxGatewayDashboard` cookie. SignalR hubs at `/hubs/{snapshot,alarms,events}` accept either the cookie or a 30-minute bearer minted at `/hubs/token`. `Dashboard:AllowAnonymousLocalhost` bypasses auth on loopback when enabled.

-## Process / Platform Notes
-
-- Working tree is on Windows (`C:\Users\dohertj2\Desktop\mxaccessgw`). PowerShell is the native shell for tooling commands; bash is fine for git/grep/find.
-- The worker reference to `ArchestrA.MXAccess.dll` uses an absolute `HintPath` to `C:\Program Files (x86)\ArchestrA\Framework\Bin\ArchestrA.MXAccess.dll`. The worker only builds where MXAccess is installed (this dev box).
-- The repo is not a git repository at the top level — there's no `.git` directory in the working tree.
