- `src/browser/`: Full-featured browser terminal with DOM rendering
- `src/headless/`: Server-side terminal for Node.js (no DOM)
- `src/common/`: Shared core logic (parsing, buffer management, terminal state)
+**Core Structure**: xterm.js is a multi-target terminal emulator with these main source areas:
+- `src/primitives/`: Building blocks (buffer, parser, input, data, utilities); TypeScript project `src/primitives/tsconfig.json`

 It's pretty common for maintainers of large open source projects to suffer from burnout, especially when needing to triage a large number of incoming issues instead of actually building things. Here are some of the steps we take to try mitigate this:

+- Support questions live in [GH discussions](https://github.com/xtermjs/xterm.js/discussions), issues may be transfered there without further comment and core maintainers may or may not participate in discussions.
 - Issues are strictly for well defined features or bugs that are _actionable_.
 - Sometimes features are out of scope. A common example of this is a niche feature that the pricipal implementation ([VS Code](https://code.visualstudio.com/)) won't leverage and therefore would be difficult to maintain and likely suffer from bitrot. The reporter may not agree with this, but you could always create an addon if that works or maintain your own fork if it comes to that.
 - If a feature does not have a clear way forward or needs more discussion it may be closed ro moved to a discussion.

 ```

 Note that browsers have offloading tricks for rarely touched memory segments, esp. `storageBytes` might not directly translate into real memory usage. Usage peaks will happen during active decoding of multiple big images due to the need of 2 full pixel buffers at the same time, which cannot be offloaded. Thus you may want to keep an eye on `pixelLimit` under limited memory conditions.  
-Further note that the formulas above do not respect the JavaScript object's overhead. Compared to the raw buffer needs the bookkeeping by these objects is rather small (<<5%).

 _Why should I care about memory usage at all?_  
-Well you don't have to, and it probably will just work fine with the addon defaults. But for bigger integrations, where much more data is held in the JavaScript context (like multiple terminals on one page), it is likely to hit the engine's memory limit sooner or later under decoding and/or storage pressure.

 _How can I adjust the memory usage?_  
 - `pixelLimit`  
-  A constructor setting, thus you would have to anticipate, whether (multiple) terminals in your page gonna do lots of concurrent decoding. Since this is normally not the case and the memory usage only peaks temporarily, a rather high value should work even with multiple terminals in one page.

 - `storageLimit`  
-  A constructor and a runtime setting. In conjunction with `storageUsage` you can do runtime checks and adjust the limit to your needs. If you have to lower the limit below the current usage, images will be removed in FIFO order and may turn into a placeholder in the terminal's scrollback (if `showPlaceholder` is set). When adjusting keep in mind to leave enough room for peak memory use during decoding.

 ### Handling Context Loss

-The browser may drop WebGL contexts for various reasons like OOM or after the system has been suspended. There is an API exposed that fires the `webglcontextlost` event on the canvas so embedders can handle it however they wish.

+# xterm.js source architecture
+
+This document describes how `src/` is organized. The layout follows [issue #5963](https://github.com/xtermjs/xterm.js/issues/5963): **primitives** and **runtime** as separate TypeScript composite projects, with **target-browser** and **target-headless** as platform entry points.
+
+## Dependency graph
+
+```mermaid
+flowchart BT
+  primitives["primitives<br/>building blocks"]
+  runtime["runtime<br/>services, integration"]
+  targetBrowser["target-browser<br/>DOM terminal"]
+  targetHeadless["target-headless<br/>Node terminal"]
+
+  runtime --> primitives
+  targetBrowser --> runtime
+  targetHeadless --> runtime
+```
+
+## TypeScript projects
+
+| Project | `tsconfig` | Output | Role |
+| --- | --- | --- | --- |
+| Primitives | `src/primitives/tsconfig.json` | `out/primitives/` | Buffer, parser, input helpers, static data, shared utilities. Must not import from `runtime/`. |
+| Runtime | `src/runtime/tsconfig.json` | `out/runtime/` | Services (DI), `CoreTerminal`, `InputHandler`, public API adapters, `Types.ts`. References primitives. |
+| Source (solution) | `src/tsconfig.json` | — | Solution root; references primitives + runtime only. |
+| Target browser | `src/target-browser/tsconfig.json` | `out/target-browser/` | Browser rendering, input, public `Terminal`. References `src/`. |
+| Target headless | `src/target-headless/tsconfig.json` | `out/target-headless/` | Headless terminal. References `src/`. |
+
+Unit test files (`**/*.test.ts`) are excluded from composite library builds; they are compiled via esbuild for `npm run test-unit`.
+
+## `primitives/`
+
+| Area | Contents |
+| --- | --- |
+| Root utilities | `Async`, `CircularList`, `Color`, `ColorTypes`, `Event`, `KeyboardTypes`, `Lifecycle`, `MultiKeyMap`, `Platform`, `SortedList`, `StringBuilder`, `TaskQueue`, `TerminalOptions`, `Version` |
+| `buffer/` | Screen buffer, `CellTypes`, `BufferService` / `BufferOptions` / `BufferLog` interfaces (buffer-layer contracts) |
+| `data/` | `Charsets`, `EscapeSequences` |
+| `input/` | UTF decoding, keyboard helpers, `UnicodeTypes`, `UnicodeProperties` |
+| `parser/` | Escape-sequence parser |
+
+Primitives depend only on other primitives (and `@xterm/xterm` typings where needed). Buffer code uses `IBufferService` from `common/buffer/BufferService`, not `common/services/Services`.
+
+## `runtime/`
+
+| Area | Contents |
+| --- | --- |
+| `services/` | DI implementations (`BufferService`, `OptionsService`, …) |
+| `public/` | Public API adapters (`AddonManager`, buffer/parser views) |
+| Root | `CoreTerminal`, `InputHandler`, `WindowsMode`, `Types.ts`, `TestUtils.test.ts` |
+
+`Types.ts` re-exports primitive types and adds integration types (`IInputHandler`, `ICoreTerminal`, mouse/color helpers, etc.).
+
+## Import paths
+
+Source keeps the `common/...` prefix (logical module name, not a physical `common/` folder). Each project's `paths` in `tsconfig.json` map that prefix to `primitives/` and/or `runtime/`.
+
+Platform code uses:
+
+- `target-browser/...` — browser terminal
+- `target-headless/...` — Node terminal
+
+## Published packages vs source folders
+
+The npm package directory `headless/` (e.g. `headless/lib-headless/`) is unchanged; only the **source** tree uses `src/target-headless/`.
+
+## Related issues

+- [#5896](https://github.com/xtermjs/xterm.js/issues/5896) — relative imports
