+# DocumentAutomation
+
+Первый локальный прототип состоит из независимых `DOCX Workbench` и `Standards Workbench` на .NET 8 Windows Forms.
+
+DOCX Workbench анализирует DOCX через Open XML, формирует документ через локальный Microsoft Word COM, сохраняет шаблонные секции/колонтитулы, обновляет поля и экспортирует PDF. Standards Workbench импортирует PDF, сохраняет checksum, извлекает страницы и кандидатные пункты, обращается к Ollama только за предложением candidate-rule и экспортирует переносимый профиль.
+
+## Ограничения MVP
+
+- OCR только обозначен интерфейсом; страницы без текстового слоя получают статус `OCR_REQUIRED`.
+- Автоматическое утверждение нормативных правил запрещено.
+- Word COM требует установленного Microsoft Word и запускается только интерактивно, не как service.
+- Реальный `156-титул-ПД.docx` и нормативные PDF не добавлялись в Git.
+- PDF preview использует локальный Word ExportAsFixedFormat.
+
+Подробности: `docs/architecture.md`, `docs/docx-template-contract.md`, `docs/word-com-lifecycle.md`, `docs/standards-rule-model.md`.

+# Architecture
+
+`DocxWorkbench.App` and `StandardsWorkbench.App` are separate WinForms applications. They share only DTOs in `DocumentAutomation.Shared`.
+
+DOCX flow: GUI -> `DocxWorkbench.Core` contracts -> `DocxWorkbench.OpenXml` read-only inspection or `DocxWorkbench.WordInterop` sequential Word COM queue -> DOCX/PDF and technical JSON log.
+
+Standards flow: GUI -> `StandardsWorkbench.Pdf` page/clause extraction and `StandardsWorkbench.Ollama` candidate-only suggestions -> manually approved portable profile -> `StandardsWorkbench.Core.RulesEngine`.
+
+COM is isolated from Core and UI. Standards rules are not hardcoded into document generation.

+# DOCX template contract
+
+The preferred insertion point is a Content Control with tag or title `DOC_BODY`, then a bookmark named `DOC_BODY`, then the exact marker `{{DOC_BODY}}`. If none is present, generation fails explicitly; the body is never silently appended.
+
+The template is copied to a temporary working file. Body headers/footers are not imported. Template sections and headers/footers are retained, fields are updated, and Word repaginates before saving.
+
+Before Word starts, the template is checked for the insertion point. If none is found, the build is rejected without starting Word. The GUI routes `.docx` through Open XML and `.txt` through `TextDocumentInspector`; template and body analysis results remain independent.

+PDF metadata includes SHA-256, page count, text-layer status and import time. Pages without text are marked `OCR_REQUIRED`; no text is invented. Clause extraction preserves clause number, text, page and confidence.
+
+Ollama receives only a small clause context and may return a candidate JSON rule. Candidates remain `New` until human approval. Only `Approved`, `Implemented` or `Tested` rules are evaluated. Profiles contain manifest, approved rules, references and a signature hash.

+# Learned document templates
+
+DOCX Workbench supports two deterministic workflows:
+
+1. `TemplateLearningService` normalizes a `.doc` or copies a `.docx` into a temporary working directory, inspects it, adds a safe `{{DOC_BODY}}` insertion marker to the working copy, and writes a portable `.dtemplate` ZIP package.
+2. `TemplateDocumentGenerator` opens the package, replaces explicitly supplied scalar tokens, imports a `.doc`, `.docx`, or `.txt` body through the existing main-story importer, and creates DOCX, PDF, generation, and validation outputs.
+
+The package contains `manifest.json`, `template.docx`, source metadata, page archetypes, regions, slots, field bindings, mapping suggestions, and a validation profile. It contains no original source binary unless it is the normalized template copy.
+
+All Word automation is late-bound and serialized through the existing STA queue. Binary `.doc` sources are opened read-only, macros are disabled through Word automation security, and the source SHA-256 is checked before and after normalization. The source body’s headers, footers, section properties, and page setup are excluded by `DocxBodyImporter`.
+
+The current UI exposes three modes: template learning, document generation, and the existing quick `DOC_BODY` path. Page archetypes and slot proposals are deterministic suggestions and require later user confirmation; Ollama is not required for the workflow.
+
+Known limitation: the first slice stores the learned structural model and default slots, but does not yet provide a pixel-level page editor or automatic extraction of every scalar field from an arbitrary engineering drawing. Those operations remain explicit user mapping work.

DocumentAutomation/docs/word-com-lifecycle.md

+# Word COM lifecycle
+
+Word is resolved late-bound through `Word.Application`; the Word PIA and `office.dll` are not required at application load time. Each service owns one serial `StaWordQueue`, and every Word job runs on its dedicated STA thread with `Visible=false` and alerts disabled. The service opens a working copy, performs one operation, updates fields, repaginates, saves, closes the Document, quits the Application, and releases owned COM proxies in `finally`.
+
+The prototype does not run as a Windows Service, does not kill unrelated `WINWORD.EXE` processes, and does not execute macros. Integration tests compare process IDs before and after each job and verify that no newly-created Word process remains.

+# P_Rec_Annot Plant 3D 2026 foundation
+
+Foundation for migration from the legacy P_Rec_Annot v1.0.4. Legacy sources remain read-only and are not copied here.
+
+Current slice:
+
+* `PRecAnnot.Abstractions` — Autodesk-free immutable contracts and DTOs;
+* `PRecAnnot.Core` — deterministic annotation planning and duplicate filtering;
+* `PRecAnnot.Application` — command registry and use-case orchestration;
+* `PRecAnnot.Plant3D2026` — guarded adapter boundary; compilation against Plant 3D 2026 is blocked until the SDK/runtime is installed;
+* `PRecAnnot.UI` — idempotent Ribbon registration model, without legacy `_netload`;
+* `PRecAnnot.Telemetry` — local JSONL command-scope events, without project path/number;
+* `PRecAnnot.Bundle.Tests` and `PRecAnnot.Core.Tests` — architecture/core/packaging checks.
+
+The first vertical slice is intentionally a dry-run planning slice. It does not mutate DWG until the Plant 3D 2026 adapter is compiled and runtime-tested on a controlled project.
+
+Build:
+
+```powershell
+dotnet build .\PRecAnnot2026.sln --configuration Release
+dotnet test .\PRecAnnot2026.sln --configuration Release --no-build
+```
+
+When Plant 3D 2026 is installed, pass `/p:Plant3D2026InstallDir=...`. Autodesk assemblies are `Private=false`, `CopyLocal=false` and are never committed.

+# Target architecture
+
+Core and Abstractions have no Autodesk, WinForms or WPF references. Only `PRecAnnot.Plant3D2026` may reference installed Autodesk assemblies. DWG mutation remains synchronous on AutoCAD's thread; no `Task.Run` is used for database operations. Ribbon registration is guarded and unloadable. The bundle has one entry assembly and no legacy `_netload` chain.

+`PRecAnnot.Plant3D2026` now compiles against the real AutoCAD/Plant 3D 2026 metadata. The adapter has real `IExtensionApplication`, `CommandMethod`, `PlantApplication.CurrentProject`, `Document`, `Editor`, and `Autodesk.Windows` Ribbon references. The previous conditional foundation-only adapter was removed. Autodesk references are `Private=false` and `CopyLocal=false`.
+
+Release emits one non-fatal WindowsBase reference conflict caused by Autodesk's legacy reference surface versus the .NET 8 reference pack. It does not copy Autodesk assemblies to output. Autodesk DLLs are excluded from Git, NuGet, bundle, and publish output.
+
+The local smoke bundle is created at `Plant3D2026\P_Rec_Annot\artifacts\P_Rec_Annot.bundle`. Deploy is NOT PERFORMED.

+| Dry-run plan | Deterministic Core builder with DTO boundary and Apply guard; no annotation writes |
+| Production deploy | NOT PERFORMED |
+
+Fixed API assumptions: foundation-only lifecycle became `IExtensionApplication`; command descriptors became actual `CommandMethod` registrations; Ortho detection uses `OrthoDocUtils.IsValidOrthoDrawing` plus the Ortho project part; viewport metadata uses `DwgSheetDefinitions`/`DwgViewDefs`; object properties use read-only `DataLinksManager.SelectAcPpRowIds` and `GetAllProperties`; Core receives only immutable DTOs. Remaining blockers are a controlled Ortho fixture, geometry/object-to-viewport mapping, legacy source provenance, and future Apply implementation.

+# Plant 3D 2026 runtime smoke results
+
+## Scope
+
+The smoke test used a temporary per-user bundle installation only. Production deploy was not performed. The temporary installation was removed after AutoCAD closed.
+
+## Confirmed
+
+- Manual `NETLOAD` loaded the P_Rec_Annot entry assembly in AutoCAD Plant 3D 2026.
+- `PHP_REC_ANNOT`, `PXP-AAV`, and `PXP-OA` were accepted by the command line.
+- The active Plant project was detected as `DefaultProject`.
+- The user confirmed Smoke mode behavior and no DWG mutation during the manual smoke interaction.
+- The runtime log contains one assembly initialization and one normal termination for the observed process.
+- The runtime log records Ribbon creation with status `Created`.
+- The runtime log records exactly one `CommandUsageEvent` for each of the three commands.
+- The observed Plant context reported `DataLinksAvailable=true` and `IsOrthoDrawing=false` for `Floor Plan Sample.dwg`.
+- No unhandled exception was reported in the captured runtime log.
+
+## Not confirmed
+
+- Automatic AppLoader loading without `NETLOAD` was not tested.
+- DBMOD and byte-level DWG/DCF/Project.xml comparisons were not captured by the smoke evidence.
+- Ribbon duplicate behavior across workspace/document lifecycle was not exhaustively tested.
+- A command invocation logged as `RuntimeMode=Smoke` is not present in the captured JSONL; the three detailed command records have `RuntimeMode=Normal`.
+
+## Evidence handling
+
+The detailed runtime JSONL remains local under `%LOCALAPPDATA%\Promhimproekt\PRecAnnot2026\Logs\` and is not committed. No DWG, DCF, Project.xml, Autodesk DLL, user identity, project path, or full local runtime path is included in the repository.
+
+Temporary installation: PERFORMED AND REMOVED.
+Production deploy: NOT PERFORMED.

+Runtime smoke is ready but has not been executed in AutoCAD. The local package is `Plant3D2026\P_Rec_Annot\artifacts\P_Rec_Annot.bundle`.
+
+Next-step installation command (intentionally not executed):
+
+```powershell
+Copy-Item -Recurse -Force .\Plant3D2026\P_Rec_Annot\artifacts\P_Rec_Annot.bundle `
+  "$env:APPDATA\Autodesk\ApplicationPlugins\P_Rec_Annot.bundle"
+```
+
+In a controlled Plant 3D 2026 session, verify that the entry assembly loads, the `Промхимпроект` tab and `Аннотации` panel occur once, and the `Аннотировать` button invokes `PHP_REC_ANNOT`. Open a Plant project and active DWG, run all three commands, verify the project guard and diagnostic-only behavior, and confirm no unhandled exception. Repeat initialization and confirm no Ribbon duplicate. DWG mutation, Ortho viewport/data-link behavior, undo, repeat-run idempotence, and golden-DWG comparison remain runtime blockers for the implementation wave.
+
+Deploy status: NOT PERFORMED.
+# Current slice: Ortho read / dry-run
+
+`P_REC_ANNOT_RUNTIME_MODE=Smoke` reads context only. `DryRun` reads Ortho view metadata and DataLinks properties, builds an immutable deterministic `AnnotationPlan`, and never applies it. `Apply` is blocked with `APPLY_MODE_NOT_IMPLEMENTED`; unknown values resolve to `DryRun`.
+
+The read adapter uses `OrthoDocUtils.IsValidOrthoDrawing`, `OrthoProject.DwgSheetDefinitions`, `IDwgViewDef`, and read-only `DataLinksManager` methods. The adapter does not expose AutoCAD or Plant objects to Core and contains no write calls. A runtime DryRun result is not published until a controlled test Ortho DWG is available; see `docs/evidence/ortho-dry-run-summary.json`.

+# Launcher source architecture audit
+
+Static, read-only audit of three independent nested Git repositories under `C:\dev\launcher\git` and the linked bootstrap repository `C:\dev\p_serv_starter`. No launcher executable, helper, build, installer, registry action, profile change, or AutoCAD process was run.
+
+The three projects are all independent WinForms `WinExe` applications, not a three-project solution: `All_Serv_Install`, `All_Serv_InstallUpdater`, and `All_Serv_Load`. Each solution contains exactly one project and has Debug/Release AnyCPU `Build.0` enabled. There are no project references between them.
+
+The current primary installer is `All_Serv_Install.exe` (v1.1.0.0). It presents a Form1 UI, reads server-side settings, copies selected corporate application directories to local targets, then starts a configured external executable. `All_Serv_InstallUpdater.exe` is a visible but short-lived self-updater: it updates the local installer with MD5 checks and starts `All_Serv_Install.exe`. `All_Serv_Load.exe` is an earlier separate WinForms loader (v1.0.0.0); source evidence does not establish that it is part of the current primary workflow.
+
+No static source evidence shows a direct reference to `app_netload.lsp`, `OrthoLoader.dll`, or `P_Rec_Annot` in the updater. The installer configuration does establish `P_Rec_Annot` deployment: catalog `P_Rec_Annot`, install file `OrthoLoader.dll`, source DriveA, target `C:\AutoCAD User Support\Applications`.
+
+`P_Serv_Starter.exe` is the confirmed external bootstrap selected by the Plant 3D installer pattern. Its source creates `_app_netload.lsp` from the installer `Settings.xml`, copies `launcher_starter.lsp` to the local Applications directory, and launches the configured local `start_plant_3d.bat`. The LISP renames the generated file to `app_netload.lsp`, adds the local Applications directory to SupportPath, and loads it. The source comment attributes LISP auto-start to `acaddoc.lsp`, but that file and the expected local installation were absent on this workstation during the audit; automatic startup remains `UNKNOWN`.

+# Application synchronization analysis
+
+`All_Serv_Install` is a synchronizing installer, not merely a launcher. It reads server `Settings.xml`, selects products/plugins, and recursively copies application directories from configured network roots to local targets. Its copy path includes directory deletion and file deletion (`Form1.cs:396-645`), so it was not executed for this audit.
+
+For Plant 3D_2019, the configuration specifies DriveA and DriveQ network sources and local target `C:\AutoCAD User Support\Applications`. The catalog `P_Rec_Annot` is selected with install entry `OrthoLoader.dll`; `download_list_plant.xml` maps the P_Rec_Annot plugin ID to a real area. This proves the intended local deployment source and target, but not the state of a particular workstation installation.
+
+`All_Serv_InstallUpdater` is a separate local updater. Its `Form1_Load` computes MD5 checksums, compares a server control-sums manifest, deletes stale local files, copies changed files, writes a local control-sums file and starts `All_Serv_Install.exe`. It references `N:\BIM\save\All_Serv_Install` and `N:\BIM\data_write\All_Serv_Install`; it can write both local and server test/control files. It was not executed.
+
+| Component | Source | Target | Version check | Destructive operations | Role | Confidence |
+|---|---|---|---|---|---|---|
+| All_Serv_Install | configured network DriveA/DriveQ | configured local target | configuration-driven selection; no content hash established | recursive copy, delete files/directories | application synchronizer | CONFIRMED |
+| All_Serv_InstallUpdater | server installer directories | updater own local directory | MD5 control sums | deletes stale local files; writes control sums | installer updater | CONFIRMED |
+| P_Serv_Starter | local installed executable + installer Settings.xml | local Applications | none | overwrites `_app_netload.lsp` and `launcher_starter.lsp` | per-launch bootstrap | CONFIRMED |
+
+Offline behavior is `UNKNOWN`: both installer and updater require configured paths at the point they run, but source evidence does not show an explicit offline fallback.

+  -> separate historical/alternate loader; no source dependency edge to the above
+```
+
+There are no ProjectReference edges between the three projects beneath `C:\dev\launcher\git`; each is its own one-project solution. `P_Serv_Starter` is a fourth independent repository selected by configuration, not a project reference. This explains why a user can experience one product despite multiple executables: the updater can hand off to the visible installer, which synchronizes selected applications and delegates Plant startup to a hidden bootstrap. Actual deployed shortcut/entrypoint evidence was not present, so the updater's use in a specific installation remains `INFERRED`.
+
+## Roles and status
+
+| Project | Output | Role | Status | Evidence |
+|---|---|---|---|---|
+| All_Serv_Install | WinExe | visible catalog UI, synchronizer and configured process launcher | ACTIVE_PRIMARY | Form1 startup and copy/Process.Start code |
+| All_Serv_InstallUpdater | WinExe | installer self-updater then handoff | ACTIVE_UPDATER | Form1_Load MD5/copy/start code |
+| All_Serv_Load | WinExe | independent alternate/historical loader | UNKNOWN | independent Form1 and 2019 batch script; no current deployment proof |
+| P_Serv_Starter | Exe | Plant session bootstrap | ACTIVE_BOOTSTRAP | selected in installer XML; writes loader and starts batch |
+
+## Runtime chain
+
+The confirmed chain ends at execution of the local Plant start batch. The gap between that batch and `launcher_starter.lsp` automatic loading is `UNKNOWN`: no local batch, `acaddoc.lsp`, or Applications files were found. Once `launcher_starter.lsp` runs, all following load steps are source-confirmed.
+
+## Answers to the requested questions
+
+1. The three launcher projects are independent WinForms executables: installer, updater and alternate loader.
+2. `All_Serv_Install` creates the confirmed visible catalog UI.
+3. Three EXE artifacts are declared by the launcher repositories; P_Serv_Starter adds one external bootstrap EXE.
+4. No launcher project is a class library; `launcher_starter.lsp` is a copied runtime content artifact.
+5. Updater/helper/bootstrap behavior is confirmed in source; actual installed-process count is unknown.
+6. Plant launch is delegated by `All_Serv_Install` to configured `P_Serv_Starter.exe`; the bootstrap starts a local batch. A current Plant executable/profile/argument string is not proven.
+7. `app_netload.lsp` and `OrthoLoader.dll` are connected through P_Serv_Starter generated LISP and installer plugin metadata.
+8. The installer synchronizes corporate application folders to a local Applications cache; it does not load P_Rec_Annot directly.
+9. No source proof warrants modifying LAUNCHER for the new plugin yet. First validate one local entry assembly through the established catalog/bootstrap contract in a non-production pilot.

+```
+
+The final two steps are confirmed by the prior P_Rec_Annot legacy audit. The activation of `launcher_starter.lsp` is not directly implemented in `P_Serv_Starter`: `Program.cs:181` comments that `acaddoc.lsp` renames the generated file, while the copied LISP itself performs the rename and `load`. No matching installed `acaddoc.lsp`, batch file, or Applications directory existed on this workstation at audit time. Therefore automatic execution is `UNKNOWN`, not asserted.

+`All_Serv_Load/Addins/start_plant_3d.bat` contains a direct AutoCAD 2019 command using `/product PLNT3D /language "ru-RU"`, preceded by PlantCleaner and PnPPersistentCache cleanup. It is evidence only of that project's historical script; it is not evidence that current users start Plant 3D 2026 this way. No `/ld`, profile, LISP or script argument is present in that script.

+# LAUNCHER to P_Rec_Annot
+
+## Proven loading contract
+
+| Stage | Evidence | Finding | Confidence |
+|---|---|---|---|
+| Deployment selection | `All_Serv_Install/Settings.xml`; `download_lists/download_list_plant.xml` | `P_Rec_Annot` is an installer plugin catalog; its configured install file is `OrthoLoader.dll`. | CONFIRMED |
+| Local target | Plant configuration target | P_Rec_Annot is intended to be copied under `C:\AutoCAD User Support\Applications\P_Rec_Annot`. | CONFIRMED |
+| Bootstrap selection | installer Plant pattern object/arguments | `All_Serv_Install` invokes `P_Serv_Starter.exe` after install selection. | CONFIRMED |
+| Generated first load | `P_Serv_Starter/Program.cs:140-174` | For each installed DLL catalog, generated LISP emits `(command "_netload" attribute)`. Therefore `OrthoLoader.dll` is loaded from the local Applications path when its catalog exists. | CONFIRMED |
+| Generated LISP activation | `launcher_starter.lsp:74-96` | It renames `_app_netload.lsp`, adds Applications to SupportPath and `(load ...)`s `app_netload.lsp`. | CONFIRMED |
+| Automatic LISP invocation | source comment in `Program.cs:181`; no installed startup file | `acaddoc.lsp` is named by a comment, but its installed content and registration were not available. | UNKNOWN |
+| Secondary module load | legacy audit, `OrthoLoader.Ribbon.Initialize` / `OrthoLoader.Initialize` | OrthoLoader reads adjacent Settings.xml and sequentially calls `._netload` for 20 configured modules. | CONFIRMED |
+
+## P_Rec_Annot-specific implication
+
+The historic contract is not a direct network `NETLOAD`. It is a local synchronized application directory followed by a generated, per-session AutoLISP loader. A generated LISP includes the Plant project path in its first comment and conditionally emits loads only for existing local plugin catalogs. New code must not reproduce that behavior before deciding whether it is compatible, necessary and safe for Plant 3D 2026.
+
+The prior legacy audit established that `OrthoLoader.dll` is the initial assembly for P_Rec_Annot. This launcher audit establishes how the installer/bootstrap is intended to make that assembly loadable. Neither audit proves the deployed local files existed or auto-loaded on this workstation.
+
+## Integration recommendation
+
+Use one versioned, locally synchronized entry artifact only after a compatibility decision. The minimal pilot should retain the existing installer catalog/target contract, make the bootstrap load exactly one new entry assembly, and use an explicitly reviewed startup mechanism. Do not rely on an unproven AppLoader bundle or add new global `TRUSTEDPATHS`/profile mutations. The generated loader and any project-path comment are legacy behavior, not requirements for the new P_Rec_Annot until runtime validation establishes a need.
