See `docs/Uns.md`. The `/uns` **TagModal** uses **driver-typed tag-config editors**: it dispatches by the bound driver's `DriverType` to a per-driver editor (Modbus/S7/AbCip/AbLegacy/TwinCAT/Focas) via `TagConfigEditorMap`, with client-side validation via `TagConfigValidator`; unmapped drivers (OpcUaClient/Galaxy/Historian.Wonderware) fall back to the generic raw-`TagConfig`-JSON textarea. Each editor is a thin razor shell over a pure `TagConfigModel` (`FromJson`/`ToJson`/`Validate`, preserves unknown keys). To add a driver's editor, copy the Modbus template under `Components/Shared/Uns/TagEditors/` + `Uns/TagEditors/`, reusing the driver's enums + camelCase JSON property names, and register it in `TagConfigEditorMap` + `TagConfigValidator`.

Roslyn compile diagnostics + +`compilation.GetDiagnostics()` filtered to `DiagnosticSeverity.Error`. Warnings +are intentionally excluded: the canonical passthrough pattern +`return ctx.GetTag("X").Value;` triggers nullable warning CS8605 under +`NullableContextOptions.Enable` but compiles and publishes fine — flagging it in +the editor would be misleading noise that does not reflect publish reality. + +Line numbers are read from `GetMappedLineSpan()` (not `GetLineSpan()`). +`GetMappedLineSpan` honours the `#line 1` directive in the preamble, so it +returns user-source coordinates directly. Diagnostics whose +`SourceSpan.Start < preambleLength` are dropped — they are phantom wrapper +diagnostics (e.g. `CS0161` "not all code paths return a value" on the synthesized +`Run` method body when the user has not yet typed `return`) and are not the +user's fault. + +### 2. ForbiddenTypeAnalyzer + +`ForbiddenTypeAnalyzer.Analyze(compilation)` walks the wrapped syntax tree and +resolves every referenced symbol against the sandbox deny-list (namespace +prefixes `System.IO`, `System.Net`, `System.Diagnostics`, `System.Reflection`, +`System.Threading.Tasks`, etc., plus type-granular denials like +`System.Environment` and `System.Threading.Thread`). Each violation is mapped +via `tree.GetMappedLineSpan(span)` to user-source coordinates and emitted as an +error marker with code `OTSCRIPT_FORBIDDEN`. + +### 3. DependencyExtractor + +`DependencyExtractor.Extract(code).Rejections` enumerates every `ctx.GetTag` / +`ctx.SetVirtualTag` call whose first argument is NOT a string literal (variable, +concatenation, interpolation). Each rejection carries a `TextSpan` in +user-source coordinates, emitted as code `OTSCRIPT_DYNPATH`. This is the exact +same check publish enforces — the editor shows the squiggle where the literal +must appear. + +--- + +## Tag-Path Completion + +When the caret is inside the first string-literal argument of a `GetTag("…")` or +`SetVirtualTag("…")` invocation, the completion provider delegates to +`IScriptTagCatalog` instead of the semantic model. + +### IScriptTagCatalog contract + +`ScriptAnalysis/IScriptTagCatalog.cs` +`GetPathsAsync(string? filter, CancellationToken)` returns the distinct +**runtime-resolvable keys** a script may pass to `ctx.GetTag` / +`ctx.SetVirtualTag`, optionally filtered by a case-insensitive `StartsWith` +prefix. The concrete implementation `ScriptTagCatalog` reads `Tag` + +`VirtualTag` rows from `OtOpcUaConfigDbContext` and projects them as follows: + +| Tag category | Resolvable key emitted | +|---|---| +| Equipment driver tag (`EquipmentId != null`) | Driver `FullName` extracted from `Tag.TagConfig` JSON — the verified `DependencyMux` key | +| SystemPlatform / Galaxy tag (`EquipmentId == null`) | MXAccess dot-ref: `FolderPath.Name` when a folder is set, else `Name` | +| Virtual tag | Leaf `Name` (best-effort) | + +**Why only resolvable keys?** The live runtime resolves a `ctx.GetTag("X")` +literal against `DriverInstanceActor.AttributeValuePublished.FullReference`, +which is the `FullName` field from `Tag.TagConfig` +(see `Phase7Composer.ExtractTagFullName` + `EquipmentNodeWalker.ExtractFullName`). +The UNS-path engine (`Core.VirtualTags.VirtualTagEngine`, keyed by the +slash-joined `Enterprise/Site/Area/Line/Equipment/TagName` browse path) is +dormant — it is not wired into the host — so UNS browse paths never resolve at +runtime and are intentionally NOT offered as completions. + +The catalog is scoped per Blazor circuit; each call creates and disposes its own +`DbContext` via the pooled factory (same pattern as `UnsTreeService`). Results +are bounded to 200 entries to keep the completion list responsive on large fleets. + +### Literal gate + +`TryGetTagPathLiteral` identifies the tag-path context by climbing from the +syntax token under the caret to: `LiteralExpressionSyntax` → `ArgumentSyntax` +(first argument only) → `ArgumentListSyntax` → `InvocationExpressionSyntax` → +`MemberAccessExpressionSyntax`. The method name check is +`method is "GetTag" or "SetVirtualTag"` — it matches by method name only, not +by receiver type, so `anything.GetTag("…")` would also trigger tag-path +completion. This is harmless in the sandbox (no other `GetTag` methods exist in +the allowed reference set) and keeps the detection simple. + +--- + +## Vendoring / Air-gap Safety + +Monaco is served from +`_content/ZB.MOM.WW.OtOpcUa.AdminUI/lib/monaco/vs/` (the Blazor static-asset +path for the AdminUI RCL). The loader script is at +`_content/ZB.MOM.WW.OtOpcUa.AdminUI/js/monaco-init.js`. No CDN is contacted at +runtime. The legacy CDN loader (`monaco-loader.js`) and the `eval`/`Task.Delay` +injection previously in `ScriptEdit.razor` have been removed. + +--- + +## Wire-in Points + +### ScriptEdit page (`/scripts/{id}`) + +`src/Server/ZB.MOM.WW.OtOpcUa.AdminUI/Components/Pages/ScriptEdit.razor` + +Hosts ``. On save, SHA-256 is +recomputed from the editor value and stored in `Script.SourceHash` — unchanged +from the pre-Monaco save path. + +### VirtualTagModal (`/uns` TagModal for virtual tags) + +`src/Server/ZB.MOM.WW.OtOpcUa.AdminUI/Components/Shared/Uns/VirtualTagModal.razor` + +When the selected script has a `ScriptId`, an inline "Script source" panel +renders `` bound to the script source. The panel shows a +**"Used by N virtual tag(s)"** notice (populated from +`IUnsTreeService.CountVirtualTagsUsingScriptAsync`). A dedicated **Save script** +button calls `IUnsTreeService.UpdateScriptSourceAsync`, which performs a +`RowVersion`-guarded update of the `Script` row — a separate concurrency unit +from the virtual-tag Create/Save operation. Creating a brand-new script inline +from the modal is a follow-up (not v1). + +Three `IUnsTreeService` methods back the inline panel: +`GetScriptSourceAsync` / `CountVirtualTagsUsingScriptAsync` / +`UpdateScriptSourceAsync`. + +--- + +## How to Extend + +### Adding a new completion source + +1. Implement a new case in `ScriptAnalysisService.CompleteAsync`. The + `Analyze(code)` seam gives you the `SemanticModel`, `SyntaxTree`, and + preamble offset. +2. Add the corresponding request/response DTOs to + `ScriptAnalysisContracts.cs` if a new endpoint is needed, or fold into an + existing endpoint with an extra field. +3. Register the new Monaco provider in `monaco-init.js` using the same + `fetch('/api/script-analysis/…', { method: 'POST', … })` pattern. + +### Adding a new analysis check (diagnostics) + +Extend `Diagnose` in `ScriptAnalysisService`. The existing three-source pattern +(Roslyn → `ForbiddenTypeAnalyzer` → `DependencyExtractor`) is additive: add a +fourth source and append to `markers`. Keep severity at 8 (Monaco error) for +anything that blocks publish; use 4 (warning) for advisory-only hints. + +### Changing the tag-path catalog source + +Replace or extend the `ScriptTagCatalog` implementation of `IScriptTagCatalog`. +Register the replacement in `EndpointRouteBuilderExtensions.AddAdminUI` +(or inject via the DI container as the `IScriptTagCatalog` scoped service). + +--- + +## Known Limitations / Follow-ups + +- **Tag-path completion shows resolvable keys only.** Surfacing the UNS browse + path as a completion *detail* (a non-inserted hint shown alongside the + resolvable key) for discoverability is a tracked follow-up. +- **Literal gate matches by method name, not receiver.** `anything.GetTag("…")` + would also trigger tag-path completion (not just `ctx.GetTag("…")`). Harmless + in the sandbox today — no other `GetTag` methods exist in the allowed reference + set — but tighter binding to `ctx` / `VirtualTagContext` is a follow-up. +- **Analysis runs synchronous Roslyn (CPU-bound).** Each endpoint call builds a + `CSharpCompilation` synchronously. This is intentional: the endpoints are + admin-only, client-side debounced (~500 ms), and `Task.Run` offload adds + unnecessary complexity for infrequent admin use. If concurrency becomes a + concern under heavy admin usage, wrapping each `Analyze` call in `Task.Run` is + the correct fix. +- **InlayHints is a stub.** `/api/script-analysis/inlay-hints` returns an empty + list. Filling it in (parameter name hints from the semantic model) is a + follow-up task. +- **Language providers register globally at Monaco load.** The six providers are + registered for the `csharp` language on the global Monaco instance (loaded once + per page in `App.razor`). There is no impact today because only + `Administrator`-reachable pages host a `MonacoEditor`, but if a read-only + surface ever embeds the editor the providers will fire (harmlessly — they just + get 401 responses from the `FleetAdmin`-gated endpoints and return empty + results). +- **Creating a new script from the VirtualTagModal inline panel** is deferred. + The current inline panel loads and saves an existing `Script` row; creating a + brand-new script requires a separate create flow and is a follow-up. + +--- + +## Testing + +Unit tests live in +`tests/Server/ZB.MOM.WW.OtOpcUa.AdminUI.Tests/ScriptAnalysis/`: + +| File | Covers | +|------|--------| +| `DiagnoseTests.cs` | Clean script (no markers), Roslyn error, ForbiddenTypeAnalyzer violation, dynamic-path rejection, `#line` mapping | +| `CompletionTests.cs` | Scope completions, dot-member completions after `ctx.` | +| `TagPathCompletionTests.cs` | Tag-path literal completions inside `GetTag`/`SetVirtualTag` via a fake `IScriptTagCatalog` | +| `HoverSignatureTests.cs` | Hover markdown, signature-help parameter tracking | +| `FormatTests.cs` | `NormalizeWhitespace` round-trip | +| `ScriptTagCatalogTests.cs` | Equipment-tag `FullName`, Galaxy dot-ref, virtual-tag leaf `Name`, filter prefix, MaxResults bound | + +`tests/Server/ZB.MOM.WW.OtOpcUa.AdminUI.Tests/Uns/ScriptSourceServiceTests.cs` +covers `GetScriptSourceAsync` / `CountVirtualTagsUsingScriptAsync` / +`UpdateScriptSourceAsync` via the in-memory EF pattern. + +No bUnit tests exist for `MonacoEditor.razor` or `VirtualTagModal.razor` — the +AdminUI has no bUnit dependency.
