Two NuGet packages with a strict dependency direction:
- **`src/Terminal.Gui.Editor`** — UI-framework-independent document model. Namespace `Terminal.Gui.Editor` and subnamespaces. **Must not reference Terminal.Gui.** Holds the rope-backed `TextDocument`, `DocumentLine`, `TextAnchor`, `UndoStack`, `ITextSource`, `TextSegment`, the `Rope`, and supporting utility types. Lifted from AvaloniaEdit (see fork policy below) — `Document/` and `Utils/` are landed; `Folding/`, `Search/`, `Indentation/`, `Highlighting/` are follow-up phases per `specs/00-plan.md`.
-- **`src/Terminal.Gui.Editor`** — the `Editor : View` and cell-grid rendering pipeline. Namespace `Terminal.Gui.Views` (matches Terminal.Gui convention, deliberately not `Terminal.Gui.Editor`). References `Terminal.Gui` (version pinned via `$(TerminalGuiVersion)` in `Directory.Build.props`) and `Terminal.Gui.Editor`. Split into partials: `Editor.cs` (core: `Document`, `CaretOffset`, edit-tracking arithmetic, content-size + scroll), `Editor.Drawing.cs` (`OnDrawingContent` + cursor positioning), `Editor.Keyboard.cs` (`OnKeyDown` switch — navigation / editing / undo+redo). No selection / folding / highlighting / multi-caret yet.
+- **`src/Terminal.Gui.Editor`** — the `Editor : View` and cell-grid rendering pipeline. Namespace `Terminal.Gui.Editor` (all public types in the assembly live under `Terminal.Gui.Editor.*`). References `Terminal.Gui` (version pinned via `$(TerminalGuiVersion)` in `Directory.Build.props`). Split into partials: `Editor.cs` (core: `Document`, `CaretOffset`, edit-tracking arithmetic, content-size + scroll), `Editor.Drawing.cs` (`OnDrawingContent` + cursor positioning), `Editor.Keyboard.cs` (`OnKeyDown` switch — navigation / editing / undo+redo). Subnamespaces: `Terminal.Gui.Editor.Document`, `Terminal.Gui.Editor.Rendering`, `Terminal.Gui.Editor.Highlighting`, `Terminal.Gui.Editor.Indentation`, `Terminal.Gui.Editor.Completion`.
- **`examples/ted`** — standalone TG demo app exercising `Editor`. Not packed; not a NuGet artifact. Has a File menu, the `Editor` View, and a status bar; grows with the View. Run via `dotnet run --project examples/ted`.
The boundary matters: anything that takes a dependency on `Terminal.Gui` types belongs in `Terminal.Gui.Editor`, never in `Terminal.Gui.Editor`.

- **One public or internal type per file.** No nested types except inside the file that owns the outer type, and only when the nested type is a private implementation detail (`DocumentLine.LineNode`-style). If a nested type grows interesting, promote it to its own file.
- **No file longer than 1000 lines.** When a file approaches that, split — by partial class (`Editor.Drawing.cs`, `Editor.Mouse.cs`), by helper extraction, or by genuinely splitting the type. The cleanup hook does not enforce this; the reviewer does.
- **C# 14 `extension` blocks**: prefer extension blocks over a static class full of `this`-prefixed extension methods when the extensions form a coherent group on a single receiver type.
-- **Namespace per folder.** `src/Terminal.Gui.Editor/Document/` ⇒ `Terminal.Gui.Document`; `src/Terminal.Gui.Editor/Rendering/` ⇒ `Terminal.Gui.Views.Rendering`. Don't put unrelated types in the same namespace just because they share a folder.
+- **Namespace per folder.** `src/Terminal.Gui.Editor/Document/` ⇒ `Terminal.Gui.Editor.Document`; `src/Terminal.Gui.Editor/Rendering/` ⇒ `Terminal.Gui.Editor.Rendering`. All namespaces in the Editor assembly are rooted under `Terminal.Gui.Editor`. Don't put unrelated types in the same namespace just because they share a folder.
- **No static members on `View`-derived types.** A class that derives from `Terminal.Gui.View` (e.g. `Editor`) must not declare `static` members — not fields, not properties, not events, not even "harmless" caches or lookup tables. Terminal.Gui's `Application` lifetime is per-instance (see "Testing tiers"); static state on a View is process-global, survives across `IApplication` instances, and silently couples otherwise-independent windows and parallel tests (the canonical cause of parallel-test hangs). Shared/lookup data lives in a dedicated non-View type (e.g. `XshdRoleMap`), exposed read-only (`private` + `FrozenDictionary`/`IReadOnlyXxx`), and is injected or queried — never hung off the View. `const` is the only exception (it is not state). This is a hard rule; a reviewer blocks on it.
