+## Назначение проекта
+
+Этот репозиторий содержит аудит, архитектуру, исходный код, тесты, runtime
+evidence и документацию миграции корпоративной экосистемы Autodesk AutoCAD
+Plant 3D 2019 на Autodesk AutoCAD Plant 3D 2026.
+
+Конечная цель — функционально эквивалентная рабочая схема Plant 3D 2026:
+корпоративный Launcher, локальная доставка и активация пакетов, managed
+плагины, команды, Ribbon, Plant project integration, DataLinks, Ortho,
+аннотации, обновление, диагностика и rollback. Миграция не считается
+завершённой после успешной компиляции: необходима runtime-проверка реальных
+сценариев в Plant 3D 2026.
+
+## Связанные репозитории
+
+- основной Autodesk-репозиторий: `C:\dev\autodesk`;
+- Launcher Next: `C:\dev\launcher-next`;
+- legacy launcher (read-only): `C:\dev\launcher\git`, `C:\dev\p_serv_starter`;
+- legacy P_Rec_Annot (read-only): `C:\dev\autodesk\link\P_Rec_Annot\v1.0.4\repo`.
+
+Legacy и deployed-файлы нельзя изменять без отдельного прямого задания.
+
+## Целевая платформа и принцип миграции
+
+- Autodesk AutoCAD Plant 3D 2026, series R25.1, Windows x64, .NET 8;
+- использовать реальные Autodesk 2026 managed assemblies;
+- managed package загружается локально, не напрямую с UNC;
+- Autodesk DLL нельзя коммитить, помещать в package/fixture или публиковать.
+
+Переносится функциональное поведение, а не историческая структура файлов. Не
+воспроизводить без отдельного доказательства 20 последовательных `NETLOAD`,
+legacy LISP bootstrap, `OrthoLoader.dll`, загрузку с сети или прежние
+workaround. Предпочтительная цепочка:
+
+`Launcher Next → versioned local package → один managed entry assembly → internal dependencies → commands and Ribbon`.
+
+## Статус legacy-команд
+
+Ни одна активная команда Plant 3D 2019 не исчезает молча. Для каждой команды
+фиксируется ровно один статус: `IMPLEMENTED`, `RUNTIME_VERIFIED`,
+`REPLACED_WITH_NATIVE`, `RETIRED_APPROVED` или `BLOCKED_WITH_REASON`.
+Aliases сохраняются, пока их удаление не утверждено отдельно.
+
+## Runtime уровни
+
+`Smoke` проверяет assembly load, регистрацию команд, Plant context, Ribbon,
+отсутствие необработанных исключений и отсутствие записи в DWG.
+
+`DryRun` проверяет реальные Plant data, Ortho/sheet/view definitions, DataLinks,
+Plant objects, детерминированный план и отсутствие записи в DWG/project DB.
+
+`Apply` разрешается только отдельным явным заданием: write guard, ограниченная
+DWG transaction, тестовая копия проекта, baseline, rollback/UNDO, duplicate
+protection и runtime evidence обязательны. Apply нельзя включать только
+локальной конфигурацией.
+
+## Runtime важнее предположений
+
+Build и unit tests не доказывают Autodesk integration. Для
+`RUNTIME_VERIFIED` необходимы фактические результаты: команда, module path,
+DBMOD, Ribbon, DataLinks, Ortho status, telemetry и состояние файлов после
+закрытия. Не выдумывать UI evidence: использовать `null`, `NOT VERIFIED` или
+`BLOCKED WITH REASON`.
+
+На тестовой машине реальный Plant 3D запуск разрешён, если он входит в задачу
+и есть test branch, локальный fixture, пройденные build/tests, rollback и нет
+production deploy. Не создавать искусственный review-gate перед Process.Start.
+Остановка допустима лишь после завершения доступной части работы и при
+конкретном внешнем blocker: установка, ОС, права, Autodesk runtime, fixture или
+необходимость production-данных.
+
+## Test fixtures и отсутствие записи
+
+Fixtures создаются вне Git, например `<TEST_FIXTURE_ROOT>`. Ortho fixture —
+настоящий Plant project с Pipe, DataLinks row, line group, Ortho drawing,
+Ortho viewport и source-model connection; обычный AutoCAD viewport не годится.
+Production DWG/project использовать нельзя без прямого разрешения.
+
+Нельзя коммитить DWG, DCF, Project.xml с runtime-data, project DB, Ortho
+generated files или реальные engineering values.
+
+Для Smoke/DryRun проверять DBMOD до/после, SHA-256 содержательных project
+files, отсутствие непредусмотренных transactions/DCF/project-metadata writes.
+`LastWriteTime` недостаточен. Отделять служебные Plant cache/session files от
+содержательных данных.
+
+## Ribbon, механика и evidence
+
+Ribbon — часть продукта: проверять tab, panel, button, command binding, stable
+IDs, отсутствие дубликатов при документах/workspace/reinitialization. Команда
+может быть отдельно рабочей, но plugin slice не завершён без Ribbon evidence
+или отдельного UI defect.
+
+Документировать каждую runtime-цепочку: component/project/class/method,
+input/output, Autodesk transaction mode, writes, telemetry, failure code и
+rollback action. Документация соответствует фактическому коду.
+
+Evidence содержит только проверенные значения. Не добавлять username, permit,
+полный environment, real project paths/line numbers/ObjectId/RowId/properties,
+полные logs, local manifest или startup scripts. Путь fixture заменять на
+`<TEST_FIXTURE_ROOT>`.
+
+## Warnings и Git
+
+Известный `MSB3277` WindowsBase 4.0.0.0/8.0.0.0 допустим только при полном
+совпадении с ранее зафиксированным warning. Новые warnings исследовать; не
+подавлять `NoWarn` без причины.
+
+Запрещены force push, amend/rebase опубликованной истории, push binaries,
+изменение неизвестного remote и production deployment из test branch. Перед
+commit выполнять:
+
+```powershell
+git diff --check
+git status --short
+git diff --cached --check
+```
+
+Не смешивать Launcher defect, plugin defect, runtime evidence и unrelated
+formatting в одном commit.
+
+## Definition of Done
+
+Срез завершён, когда реализованы код, build/tests, валидный package и требуемый
+runtime-сценарий; записаны фактические результаты; выполнен rollback; fixture и
+production изолированы; механика документирована; ветка опубликована обычным
+push.
+
+## Общая карта проекта
+
+Каноническая общая карта проекта находится в Google Drive:
+`https://drive.google.com/drive/folders/1avnR0V8q7y5pfWRYwB6LPBEEyfpN7PpV`.
+Локальная синхронизированная копия, если она доступна, определяется только
+переменной среды `PHIM_PLANT3D_PROJECT_MAP_ROOT`; её путь не хардкодить.
+
+Перед работой над архитектурой, миграцией или runtime-сценарием обязательно
+прочитать доступные индекс/обзор карты, целевую архитектуру и migration status,
+индекс runtime evidence, а также записи карты для затрагиваемых Launcher и
+P_Rec_Annot. Затем сверить их с локальными AGENTS.md, релевантными tracked
+документами, текущим кодом и тестами.
+
+Источники истины имеют следующий приоритет: фактическое runtime evidence;
+текущий код, tests и tracked configuration на проверенном Git HEAD; tracked
+документация репозитория; общая карта проекта. Внешняя карта описывает и
+связывает работу, но не является build/runtime dependency и не переопределяет
+текущий код или runtime evidence.
+
+Проверять свежесть каждой используемой записи карты по фактическим `git
+rev-parse HEAD`, ветке и привязанному runtime evidence. Если карта или её
+локальная копия недоступна, фиксировать `PROJECT_MAP_UNAVAILABLE`; если
+зафиксированные commit/runtime status не совпадают с фактическими —
+`PROJECT_MAP_STALE`. Эти статусы не разрешают выдумывать evidence: продолжать
+по доступным локальным источникам и явно сообщать расхождение.
+
+Системные инварианты сохраняются: Launcher доставляет versioned local package
+с одним managed entry assembly и без Autodesk DLL; P_Rec_Annot подтверждает
+реальное Plant/Ortho/DataLinks поведение runtime evidence, а не только build
+или tests. После изменения архитектуры либо runtime-статуса в отчёте указывать
+конкретные документы общей карты, которые требуют обновления (архитектура,
+статус миграции, evidence index и запись затронутой подсистемы); не заявлять,
+что они уже обновлены, без фактического изменения.

 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.

+# 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.

 # Word COM lifecycle
 
-Word is started in a dedicated task 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 objects in `finally`.
+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. Production hardening should add an explicit serial queue and PID-scoped orphan check.
+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.

+# AGENTS.md — P_Rec_Annot
+
+## Назначение и package
+
+`P_Rec_Annot` — приоритетный Plant 3D 2026 plugin для чтения, планирования и
+последующего создания Ortho-аннотаций; это перенос активного legacy поведения
+Plant 3D 2019 на .NET 8/Plant 3D 2026.
+
+Единственная assembly для `NETLOAD` — `PRecAnnot.Plant3D2026.dll`.
+`PRecAnnot.*.dll` — internal managed dependencies, их нельзя NETLOAD по одной.
+Использовать Autodesk 2026 references; Autodesk DLL не включать в bundle.
+
+## Commands и context
+
+Поддерживаемые команды: `PHP_REC_ANNOT`, `PXP-AAV`, `PXP-OA`. Все
+регистрируются реальным Autodesk API, работают в Smoke/DryRun, не изменяют DWG
+в этих режимах и создают одно usage event на явный вызов.
+
+Project status: `NotFound`, `FoundWithName`, `FoundWithoutDisplayName`,
+`Ambiguous`, `Failed`. Никогда не выводить `проект '' найден`; для пустого
+display name: `Plant 3D-проект открыт; отображаемое имя не определено.`
+Diagnostic code: `PLANT_PROJECT_DISPLAY_NAME_EMPTY`.
+
+Drawing states: `Ortho`, `NotOrtho`, `Ambiguous`, `Failed`. Обычный DWG не
+классифицируется как Ortho; для реального Ortho применять Autodesk API и
+`OrthoDocUtils.IsValidOrthoDrawing`.
+
+## DryRun и determinism
+
+Pipeline: `Plant context → Ortho detection → sheet/view definitions → viewport
+snapshots → DataLinks → Plant properties → independent DTO → deterministic
+AnnotationPlan → diagnostics → no write`.
+
+Autodesk objects, transactions и database handles остаются в adapter layer;
+Core/Application используют только независимые DTO. На неизменном fixture
+повторный DryRun обязан давать тот же PlanId, counts, порядок операций и warning
+codes, без side effects. PlanId не включает время, GUID, absolute path,
+нестабильный ObjectId или пользовательские данные.
+
+## Write guard, Ribbon, tests
+
+Все writes проходят централизованный write guard; в Smoke/DryRun он всегда
+запрещает изменения. Apply не обходится через command handler/adapter.
+
+Ожидаемый Ribbon путь: `Промхимпроект → Аннотации → Аннотировать`. Требуются
+stable IDs, отсутствие дублей, binding к `PHP_REC_ANNOT`, устойчивость к
+документам/workspace и корректный Terminate.
+
+Unit tests не требуют Autodesk runtime. Runtime evidence отдельно фиксирует
+initialization, commands, context, Ortho, DataLinks, plan, Ribbon, DBMOD,
+telemetry и shutdown.
+
+Bundle содержит только фактический runtime dependency graph и никогда не
+содержит Autodesk DLL, PDB, test assemblies, legacy 2019 assemblies, bin/obj
+или production configuration.
+
+Fixture: local Plant 3D 2026 project вне Git с настоящей Pipe, synthetic line
+number, Ortho drawing/viewport и SHA baseline до DryRun.
+
+## Viewport membership and source DataLinks
+
+Legacy P_Rec_Annot source for read-only analysis is
+`\\phpsrv03\NBIM\code\CS\P_Rec_Annot\v1.0.4\repo`.
+
+A source object is not a member of an Ortho viewport without confirmed
+evidence. A geometry-only filter is at most `PartiallyResolved`. Apply is
+blocked by any `PLUGIN_ONLY_CHANGE` in a DWG, DCF, or project metadata found by
+a paired CONTROL/DryRun comparison.
+
+## Ortho source DataLinks and DCF control
+
+DataLinks активного Ortho drawing не являются источником Piping rows. Piping
+rows читаются из source model drawing и Piping project part, разрешённых через
+Ortho sheet/view definitions.
+
+Перед предположениями об Autodesk runtime API необходимо исследовать текущий
+код, доступный legacy usage, assembly metadata и реальные runtime types.
+Reflection/runtime inspection применяется только для подтверждения данных,
+которых нельзя установить статически. Production resolver не угадывает
+Autodesk properties по строковым именам.
+
+Подтверждённый контракт Plant 3D 2026: `IDwgViewDef.DwgQuery` →
+`IDwgQuery.ModelFiles` → `ModelFile[].ModelFileName`. При несовпадении типа
+возвращать `ORTHO_MODEL_FILES_API_UNSUPPORTED`, без fallback-эвристики.
+
+Проверка DCF выполняется на парных `control` и `DryRun` fixtures, созданных из
+одного закрытого состояния проекта. Сравнивать нужно `control delta` с
+`DryRun delta`: одинаковые изменения классифицируются как baseline behavior
+Plant 3D, а plugin-only изменения блокируют дальнейшую работу.
+
+## Общая карта проекта
+
+Каноническая общая карта проекта:
+`https://drive.google.com/drive/folders/1avnR0V8q7y5pfWRYwB6LPBEEyfpN7PpV`.
+Необязательная локальная копия доступна только через
+`PHIM_PLANT3D_PROJECT_MAP_ROOT`; локальный путь синхронизации не хардкодить.
+
+До изменения P_Rec_Annot читать доступные индекс карты, запись архитектуры и
+статуса P_Rec_Annot, DryRun/Apply contract, карту Ortho/DataLinks и связанный
+runtime evidence index. Сверять их с фактическим Git HEAD, текущими plugin
+code/tests/configuration и runtime evidence конкретной fixture.
+
+Приоритет источников: runtime evidence, затем code/tests/configuration на
+проверенном HEAD, затем tracked repository documentation, затем общая карта.
+Карта не является build/runtime dependency и не заменяет фактический код либо
+runtime evidence. Недоступную карту отмечать `PROJECT_MAP_UNAVAILABLE`;
+несовпадение её commit/runtime status с фактическими данными —
+`PROJECT_MAP_STALE`.
+
+Инварианты P_Rec_Annot: остаётся единственная NETLOAD entry assembly, aliases
+и статусы команд не исчезают молча, Smoke/DryRun не пишут DWG, а Apply требует
+явного разрешения, локальной fixture, ограниченной transaction, evidence и
+проверяемого rollback/UNDO. Не ослаблять подтверждённый Ortho source/DataLinks
+контракт и DCF control comparison ради сведений из карты.
+
+После изменения plugin architecture или runtime-status в отчёте перечислять
+документы карты, требующие обновления: запись P_Rec_Annot, command/status,
+Ortho/DataLinks contract, DryRun/Apply/UNDO evidence и migration status. Не
+утверждать обновление внешней документации без фактического изменения.

+# 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.

Absolute paths, process data, timestamps and runtime ObjectIds are excluded.

+Runtime DryRun confirmed equal PlanIds and summaries for two calls of each supported command. Changing a relevant normalized input changes the PlanId.

+# 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.

+# CONTROL versus DryRun DCF comparison
+
+DBMOD covers only the active drawing. This procedure separately compares
+content-bearing project files after identical CONTROL and DryRun sessions.
+
+1. With Plant 3D closed and the Launcher session `RolledBack`, copy the local
+   fixture to `<FROZEN_FIXTURE>`.
+2. Create `<CONTROL_FIXTURE>` and `<DRYRUN_FIXTURE>` from that same frozen
+   state; calculate complete local SHA-256 inventories before each run.
+3. Open model and Ortho drawings in CONTROL through the same Launcher DryRun
+   launch contract, but invoke no P_Rec_Annot command. Close without saving,
+   wait for Launcher rollback, then calculate the after inventory.
+4. Repeat with DRYRUN and invoke each supported command twice. Close without
+   saving, wait for rollback, then calculate the after inventory.
+5. Compare deltas by logical relative path. Classify each content-bearing file
+   as `UNCHANGED`, `AUTODESK_BASELINE_CHANGE`, `PLUGIN_ONLY_CHANGE`, or
+   `INCONCLUSIVE`.
+
+Content-bearing groups include model DWG, Ortho DWG, `Piping.dcf`, remaining
+DCF/database files, `Project.xml` or equivalent project metadata, and Ortho
+metadata. Lock, cache, session, log, preview, and temporary files are reported
+separately and cannot establish project invariance.
+
+Any `PLUGIN_ONLY_CHANGE` blocks Apply. Full paths and hashes remain local;
+repository evidence contains only logical fixture markers, groups, counts, and
+classifications.

+# Ortho DryRun runtime result
+
+Date: 2026-08-03
+
+The local test fixture's `TestPipeOrtho.dwg` was detected as Ortho with one
+viewport. In the paired `DryRun`, `PHP_REC_ANNOT`, `PXP-AAV`, and `PXP-OA`
+each ran twice. Plugin telemetry recorded all six preflight completions without
+an unhandled exception. The command-window DBMOD output was not retained for
+this paired run, so its DBMOD value is recorded as `NOT RECORDED` rather than
+inferred from telemetry.
+
+`PlantProject.Name` was available for this fixture and rendered as
+`PRecAnnotTestProject`.
+
+The active Ortho sheet does not expose direct Piping rows and must not be used
+as a DataLinks source. Metadata inspection and a sanitized runtime probe
+confirmed `IDwgViewDef.DwgQuery.ModelFiles[].ModelFileName` as the source-model
+reference. The adapter resolves that reference through
+`PipingProject.GetPnPDrawingFiles()` and reads
+`DataLinksManager.SelectAcPpRowIds(PnPProjectDrawing.Id)`.
+
+On the paired real DryRun, one source drawing was resolved and seven source
+Plant objects were read. The confirmed view query resolved five source rows to
+the active viewport and classified two as outside the view. Each command
+reported seven skipped operations, zero writes, zero conflicts, and zero
+errors. The repeated plans were deterministic:
+
+| Command | Run 1 / run 2 PlanId |
+| --- | --- |
+| `PHP_REC_ANNOT` | `plan-AD701C7AA38D99E4C28D7D6D` |
+| `PXP-AAV` | `plan-C4FCD62F4EEBA1D1948FA22B` |
+| `PXP-OA` | `plan-C30D133E2D5B4BF4C0AF2ED1` |
+
+This verifies source-model DataLinks access, exact view membership through the
+stored view query, and repeated-plan determinism. The remaining functional
+limitation is annotation-rule coverage: all seven operations remain safe
+`Skip` operations, so no first Apply is authorised.
+
+The earlier single-fixture SHA baseline changed before the first command and
+was therefore inconclusive. A fresh paired comparison used 210-file CONTROL
+and DRYRUN copies created from the same closed frozen fixture. Both inventories
+had zero SHA-256 delta after their respective sessions. The CONTROL session
+invoked no plugin command; the DRYRUN session invoked all six commands. Thus
+the model DWG, Ortho DWG, `Piping.dcf`, project metadata, and other tracked
+content-bearing files have no plugin-only delta in this comparison. Both
+Launcher sessions completed automatic rollback to `RolledBack`.

+# Ortho viewport membership
+
+## Runtime path
+
+`EntryPoint.RunDiagnostic` reads each `OrthoViewportInfo` and calls
+`PlantObjectReader.ReadObjects`. The reader resolves source Piping rows, then
+`PlantViewportMembershipReader.Read` evaluates the stored query for that exact
+view. It maps `MdObjectId.PrjObjectId` to a source DataLinks row and assigns a
+membership status to every independent `PlantObjectSnapshot`.
+
+| Status | Meaning | Diagnostic evidence |
+| --- | --- | --- |
+| `Resolved` | The source row was returned by the exact view query. | `VIEW_MEMBERSHIP_FROM_CONFIRMED_PNP_ID` |
+| `ObjectOutsideView` | The source row was not returned by that confirmed query. | `VIEW_MEMBERSHIP_OBJECT_OUTSIDE_CLIP` |
+| `NotResolved` | The view contract is unavailable, ambiguous, or failed. | `VIEW_MEMBERSHIP_API_UNSUPPORTED` |
+
+No source object is treated as visible solely because it belongs to the same
+model drawing. No geometry-only result is upgraded to `Resolved`.
+
+## Plan effect
+
+`AnnotationPlanBuilder` includes membership status in its canonical plan input.
+`ObjectOutsideView`, unsupported, and unresolved objects are `Skip` operations
+with stable reason codes. `Resolved` membership can progress only through the
+existing annotation rules; this DryRun slice never writes an annotation.
+
+## Paired DryRun evidence
+
+The paired local DryRun resolved five of seven source rows through the exact
+view query and classified the remaining two as `ObjectOutsideView`. Each of
+the three supported commands produced an identical PlanId on its repeated
+invocation. Both Launcher sessions reached `RolledBack`.
+
+The paired command-window DBMOD output was not retained. It is intentionally
+reported as `NOT RECORDED`; project-file SHA-256 inventories nevertheless had
+zero delta for both CONTROL and DRYRUN copies.

+# Plant 3D 2026 DwgQuery / ModelFiles API contract
+
+## Scope and method
+
+This report is based on metadata-only inspection of the installed Plant 3D 2026
+assemblies. The assemblies were read from `<PLANT3D_2026_INSTALL>` and were not
+copied into the repository. Metadata-only inspection was necessary because the
+normal PowerShell host cannot load the product's .NET 8 dependencies safely.
+
+Legacy source at the documented local path was not present on this machine, so
+there is no legacy API claim in this report.
+
+## Confirmed assemblies
+
+| Assembly | Version | Relevant type |
+| --- | --- | --- |
+| `PnPDwg2dDef` | `0.0.0.0` | `Autodesk.ProcessPower.Drawings2d.DwgQuery`, `IDwgQuery`, `DwgViewDef`, `IDwgViewDef`, `DwgSheetDef`, `IDwgSheetDef` |
+| `PnPDwg2dUtil` | `0.0.0.0` | `Autodesk.ProcessPower.Drawings2d.ModelFile` |
+| `PnP3dOrthoProjectPart` | `17.0.60.1` | Ortho project-part integration assembly; the metadata scan found no public DwgQuery declaration there |
+
+`PnPDwg2dDef` and `PnPDwg2dUtil` use `0.0.0.0` assembly versions in the
+installed metadata. The supported runtime contract is therefore identified by
+the exact public type names below, not by an invented product-version number.
+
+## Confirmed contract
+
+```text
+Autodesk.ProcessPower.Drawings2d.IDwgViewDef.DwgQuery
+  : Autodesk.ProcessPower.Drawings2d.IDwgQuery
+
+Autodesk.ProcessPower.Drawings2d.IDwgQuery.ModelFiles
+  : Autodesk.ProcessPower.Drawings2d.ModelFile[]
+
+Autodesk.ProcessPower.Drawings2d.ModelFile.ModelFileName
+  : System.String
+
+Autodesk.ProcessPower.Drawings2d.ModelFile.ModelFileGuid
+  : System.String
+```
+
+`DwgViewDef` implements `IDwgViewDef`; `DwgQuery` implements `IDwgQuery` and
+`IDisposable`; `ModelFile` implements `IComparable<ModelFile>`.
+
+`ModelFiles` is an array, not an untyped enumerable. `ModelFileName` is the
+only confirmed string field representing the model-file reference. `ModelFileGuid`
+is a separate identity field. `IsReferencedDwg` and `Xform` describe reference
+state and transform, not a substitute path.
+
+## Public members relevant to source resolution
+
+`IDwgViewDef` exposes `DwgQuery`, `ViewName`, layout/orientation properties,
+and `SetClippingPlanes`, `SetLayout`, `SetOrientation`, `Erase`, and `New`.
+
+`IDwgQuery` exposes `ModelFiles`, `Execute`, and `Erase`.
+
+`ModelFile` exposes `ModelFileName`, `ModelFileGuid`, `IsReferencedDwg`, and
+`Xform`; its constructors accept a file-name string and optional transform,
+reference flag, and GUID.
+
+`IDwgSheetDef.DwgViewDefs` exposes the view-definition collection. Sheet
+`DwgName`/`DwgPath` identify the Ortho sheet and must not be used as the source
+of Piping DataLinks.
+
+## Current and legacy usage
+
+The original adapter used reflection and tried several possible names
+(`ModelFileName`, `Value`, and arbitrary string values). That was not a valid
+Plant 3D 2026 contract.
+
+The production read path now uses the confirmed typed chain only:
+
+```text
+IDwgViewDef.DwgQuery.ModelFiles[].ModelFileName
+```
+
+The legacy source path was unavailable locally, so no legacy source-model or
+DataLinks workaround has been imported.
+
+## Runtime evidence
+
+Static metadata cannot prove whether `ModelFileName` is project-relative or
+absolute in a concrete Ortho fixture, or whether a particular view has zero,
+one, or multiple model files. In DryRun only, setting
+`P_REC_ANNOT_DIAGNOSTICS=OrthoStructure` enables a sanitized structure probe.
+It records type names, collection counts, null state, string length, and a
+one-way value hash; it does not emit paths or engineering data.
+
+On the local DryRun fixture, the runtime probe recorded one view with one
+`ModelFile`. The concrete types were `DwgViewDef`, `DwgQueryByBox`, and
+`ModelFile[]`; `ModelFileName` was non-null and an absolute fixture-model
+reference. The path itself was not retained in repository evidence.
+
+The resolver resolves that reference to exactly one
+`PipingProject.GetPnPDrawingFiles()` entry by normalized full-path equality,
+then uses the confirmed `DataLinksManager.SelectAcPpRowIds(int dwgid)` overload
+with the resolved `PnPProjectDrawing.Id`. It does not open or query the active
+Ortho database for Piping rows.
+
+The production resolver has no fallback property-name search. If the exact
+contract is unavailable at runtime it reports
+`ORTHO_MODEL_FILES_API_UNSUPPORTED` rather than guessing.

+# Ortho viewport membership API
+
+## Scope
+
+This report records the Plant 3D 2026 contract used to map source-model
+DataLinks objects to one Ortho view. Autodesk binaries were inspected in
+`<PLANT3D_2026_INSTALL>` and are not part of this repository.
+
+## Confirmed Plant 3D 2026 contract
+
+| Assembly | Version | Type/member | Purpose |
+| --- | --- | --- | --- |
+| `PnPDwg2dDef` | `0.0.0.0` | `IDwgViewDef.DwgQuery` | Returns the query stored by an Ortho view. |
+| `PnPDwg2dDef` | `0.0.0.0` | `DwgQueryByBox.Execute(StringCollection, StringCollection)` | Executes the stored view selection and returns `IDwgSet`. |
+| `PnPDwg2dDef` | `0.0.0.0` | `IDwgSet.GetItem(int, ref MdObjectId)` | Enumerates selected source identities. |
+| `PnPDwg2dUtil` | `0.0.0.0` | `MdObjectId.PrjObjectId` | Exposes the selected project object identity. |
+| `PnPDataLinks` | `17.0.60.1` | `DataLinksManager.FindAcPpRowId(PpObjectId)` | Maps a selected project object to its DataLinks row. |
+
+`DwgQueryByBox` also exposes `CoordinateSystem`, `XLength`, `YLength`,
+`ZLength`, and `SelectionMask`. `DwgViewDef` exposes orientation, clipping,
+and layout fields. They are not used as a heuristic in this slice because the
+query result provides a stronger project-object identity.
+
+## Selected implementation
+
+`PlantViewportMembershipReader.Read` locates exactly one view by the stable
+ID already generated from the sheet GUID and view name. It executes that
+view's stored `DwgQuery`, converts every returned `MdObjectId.PrjObjectId`
+through `DataLinksManager.FindAcPpRowId`, and intersects the result with the
+source drawing's Piping rows.
+
+Matching rows receive `Resolved` with
+`VIEW_MEMBERSHIP_FROM_CONFIRMED_PNP_ID`. Source rows absent from the confirmed
+query result receive `ObjectOutsideView` with
+`VIEW_MEMBERSHIP_OBJECT_OUTSIDE_CLIP`. An unsupported or ambiguous runtime
+contract stays `NotResolved` with `VIEW_MEMBERSHIP_API_UNSUPPORTED`; the code
+does not guess alternate Autodesk properties or select an arbitrary view.
+
+## Legacy analysis
+
+The read-only legacy source at
+`\\phpsrv03\NBIM\code\CS\P_Rec_Annot\v1.0.4\repo` was available. Its
+`UpdateOrthoDrawings/Commands.cs` configured `DwgQuery.ModelFiles` and called
+`DwgQuery.Execute`; `OrthoAutoAnnotate/Commands.cs` and
+`AutoAnnotateView/ViewPorts.cs` also used viewport and entity extents. Those
+extents checks are a geometric filter, not an authoritative object identity,
+so they were not ported as `Resolved` membership.
+
+## Side effects and failure handling
+
+The reader opens no Autodesk write transaction and calls no persistence API.
+It does not modify DWG, DCF, or project metadata. `DLException` while mapping
+an individual generated identity is ignored only for that non-Piping identity;
+other failures yield the stable API diagnostic and preserve no false positive.
+Runtime DryRun and paired control/DryRun hash comparison remain required to
+verify actual no-write behavior.

+
+## 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.

+# Runtime test plan
+
+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`.

+# Autodesk Launcher architecture
+
+This section is the single architecture record for the corporate Autodesk launcher, its legacy P_Rec_Annot loading path, and the parallel Launcher Next foundation. Statements are labelled `CONFIRMED`, `HIGH_CONFIDENCE`, `INFERRED`, or `UNKNOWN` and link to the audit evidence map.
+
+The AS-IS flow is a locally synchronized legacy deployment with generated AutoLISP loading. Launcher Next is a .NET 8, one-visible-EXE design that stages signed-by-hash local packages and loads one managed entry assembly. It is a design/foundation only: production configuration, AutoCAD profiles, trusted paths, network roots and deploys were not changed.
+
+See [AS-IS](as-is/system-context.md), [target](target/architecture.md), [legacy compatibility and pilot](target/legacy-compatibility.md), [ADRs](adr/ADR-001-parallel-rewrite.md), and [evidence map](evidence-map.csv).

+- Actual runtime files and local cache were absent on the audited workstation.
+- Exact startup mechanism for every AutoCAD/Plant release and profile.
+- Network-offline behavior across all installer/updater/module branches.
+- Full per-module failure continuation, duplicate-load handling, resources and command-time network dependencies.

+# AS-IS performance profile
+
+The startup path performs network-dependent synchronization when installer/update is used, writes generated LISP files, starts a batch and may load 20 assemblies sequentially. No timings were collected; claims about latency, parallelism, cache hit rate, or behavior under unavailable network are `UNKNOWN`.
+
+| Source-level observation | Evidence | Performance implication | Confidence |
+|---|---|---|---|
+| Installer recursively copies selected catalogs and can delete files/directories | `All_Serv_Install/Form1.cs` copy path | filesystem and potentially network traversal; UI blocking behavior requires measurement | CONFIRMED |
+| Updater computes MD5/control sums and replaces local files | `All_Serv_InstallUpdater/Form1.cs` | repeat hash/read/copy work; no measured count or time | CONFIRMED |
+| Bootstrap emits one generated loader command per selected installed catalog | `P_Serv_Starter/Program.cs` | sequential startup work grows with selected modules | CONFIRMED |
+| OrthoLoader sequentially `. _netload`s 20 configured modules | legacy loading audit | 20 managed loads before all functionality is ready | CONFIRMED |
+| Repeated load on document/workspace events | no complete event evidence | cannot assert | UNKNOWN |
+
+No measured count is claimed for network requests, full copies, UI waits, `Process.WaitForExit`, `Thread.Sleep`, or repeated document-level loading. Those are measurement subjects, not observed facts.
+
+## Measurement plan (proposed)
+
+| Scenario | Start | End | Proposed metrics |
+|---|---|---|---|
+| Cold start | launcher action | Ribbon ready | elapsed time, files hashed/copied, bytes, NETLOAD count |
+| Warm start | launcher action | Ribbon ready | cache hit, network requests, elapsed time |
+| Offline start | launcher action with network unavailable | Plant prepared/started | valid cache use, retry count, user status |
+| No-update start | catalog read | launch prepared | manifest comparison and file operations |
+| Update start | catalog read | activation complete | staging time, hash time, atomic switch time |
+| Rollback | rollback request | previous pointer active | elapsed time and success/failure |
+| Plugin readiness | Plant process created | Initialize and Ribbon ready | process-start, entry-load, command/Ribbon timestamps |
+
+Targets are **PROPOSED** until baseline data is collected: one entry NETLOAD, zero network assembly loads, zero in-place replacement of active package files, and no repeated full copy on a valid no-update start.

+Legacy code writes local support files and uses generated LISP plus `NETLOAD`. It relies on the corporate local trusted support convention, but this audit did not change or verify `TRUSTEDPATHS`, profiles, registry demand loading, or deployment permissions. Network source access occurs during installation/update. The audit does not establish code signing, strong validation, complete hash coverage, or secret handling. Treat all of those as gaps.
