+# OrcaSlicer UI Automation Protocol (v1.0.0)
+
+OrcaSlicer ships an **opt-in, localhost-only JSON-RPC server** that lets external
+scripts introspect, drive, and screenshot the running OrcaSlicer GUI. It is built
+for end-to-end testing and automation: a script can enumerate the live widget
+tree, click buttons, type text, send keyboard shortcuts, wait for UI state, query
+high-level application state, load models/projects into the running instance,
+switch the active view/tab, and capture window images (the on-screen capture
+includes the 3D viewport).
+
+This document is the protocol reference. It describes activation, the transport,
+the JSON-RPC envelope, every method, the unified node shape, the target/locator
+model, error codes, the set of instrumented automation ids, ImGui specifics,
+platform caveats, a quick-start snippet, and planned future work.
+
+---
+
+## 1. Overview & activation
+
+The automation server is **OFF by default**. It is enabled with two
+command-line flags:
+
+| Flag | Meaning |
+|---|---|
+| `--automation-server` | Enable the automation server. |
+| `--automation-server-port=PORT` | Override the listening port. Optional; default is **13619**. |
+
+Example:
+
+```bash
+OrcaSlicer --automation-server --automation-server-port=13619 model.stl
+```
+
+The server binds to **`127.0.0.1` only** (the loopback interface). It is never
+exposed on an external network interface.
+
+**Security note (v1):** there is **no authentication token** in v1. The localhost
+bind is the *only* security boundary. Any process able to run code on the machine
+can connect to the port and drive the GUI — including injecting mouse and keyboard
+input — while the server is enabled. The feature is intended for testing and
+automation environments, not for production or shared/multi-user machines.
+
+When the server is enabled, OrcaSlicer emits a `warning`-level log line at startup
+to make the active input-injection surface obvious in logs, for example:
+
+```
+UI automation server ENABLED ... input injection is active
+```
+
+---
+
+## 2. Transport
+
+The server speaks **HTTP/1.1** over the loopback TCP socket:
+
+| Request | Response |
+|---|---|
+| `POST /jsonrpc` with a JSON-RPC 2.0 request body | A JSON-RPC 2.0 response with `Content-Type: application/json`. |
+| `GET /` | A plain-text health page: `OrcaSlicer automation server v1.0.0` (`Content-Type: text/plain`). |
+| Anything else | HTTP `404 Not Found`. |
+
+The server is **single-client / serialized** in v1: it handles one request at a
+time on its own dedicated I/O thread. Connections are not kept alive; each request
+is answered and the socket is closed. Clients should issue requests sequentially.
+
+---
+
+## 3. JSON-RPC envelope
+
+The protocol follows **JSON-RPC 2.0**.
+
+**Request:**
+
+```json
+{ "jsonrpc": "2.0", "id": <id>, "method": "<method>", "params": { ... } }
+```
+
+- `params` may be omitted; the server treats a missing `params` as an empty object.
+
+**Success response:**
+
+```json
+{ "jsonrpc": "2.0", "id": <id>, "result": { ... } }
+```
+
+**Error response:**
+
+```json
+{ "jsonrpc": "2.0", "id": <id>, "error": { "code": <int>, "message": "<string>" } }
+```
+
+The request `id` is echoed back in the response. When the request has no `id`, or
+when the request body cannot be parsed as JSON, the response `id` is `null`.
+
+---
+
+## 4. Methods
+
+There are 12 methods. Capabilities advertised by `automation.version` list the 11
+callable feature methods (every method except `automation.version` itself).
+
+### `automation.version`
+
+Returns server identity and the list of supported methods. Takes no parameters.
+
+**Result:**
+
+```json
+{
+  "version": "1.0.0",
+  "protocol": "2.0",
+  "capabilities": [
+    "tree.dump", "tree.find", "widget.get", "input.click", "input.type",
+    "input.key", "sync.wait_for", "app.state", "screenshot.window", "file.open",
+    "view.select"
+  ]
+}
+```
+
+### `tree.dump`
+
+Snapshot the live UI tree as a single root node with nested children.
+
+**Params (all optional):**
+
+| Param | Type | Default | Meaning |
+|---|---|---|---|
+| `root` | string (id or path) | full tree | Root the dump at the node with this id/path. |
+| `max_depth` | int | `-1` | Maximum depth to descend. `-1` = unlimited. |
+| `visible_only` | bool | `false` | When true, omit non-visible nodes. |
+| `include_imgui` | bool | `true` | When true, include ImGui items. |
+
+**Result:** the serialized root [node](#5-unified-node-shape), with `children`
+included.
+
+### `tree.find`
+
+Find all nodes matching a [target predicate](#6-target--locator).
+
+**Params:** a target predicate — any combination of `name`, `class`, `label`,
+`value`, `backend` (provided fields are ANDed). The params object is the target
+itself (it is *not* wrapped in a `target` key for this method).
+
+**Result:** a **flat JSON array** of matching nodes. The nodes in this array are
+returned **without** their `children` (use `widget.get`/`tree.dump` to descend).
+
+### `widget.get`
+
+Fetch a single node by [target](#6-target--locator).
+
+**Params:**
+
+| Param | Type | Required | Meaning |
+|---|---|---|---|
+| `target` | object | yes | Target spec (id / path / predicate). |
+
+**Result:** a single [node](#5-unified-node-shape), with its `children` included.
+
+**Errors:** `1001` if the target is **not found** *or* **ambiguous** (more than one
+match).
+
+### `input.click`
+
+Click a resolved, actionable node.
+
+**Params:**
+
+| Param | Type | Default | Meaning |
+|---|---|---|---|
+| `target` | object | required | Target spec; must resolve to exactly one node. |
+| `button` | string | `"left"` | `"left"`, `"right"`, or `"middle"`. |
+| `double` | bool | `false` | Double-click when true. |
+| `modifiers` | array of string | `[]` | Held modifiers: any of `"ctrl"`, `"shift"`, `"alt"`, `"cmd"` (`"meta"` is accepted as an alias of `"cmd"`). |
+
+**Result:** `{ "ok": true }`.
+
+**Errors:** `1001` not found / ambiguous; `1002` if the target is disabled or
+hidden (not actionable). The click path raises and focuses the target's top-level
+window before injecting the click.
+
+### `input.type`
+
+Type text into the currently focused control.
+
+**Params:**
+
+| Param | Type | Required | Meaning |
+|---|---|---|---|
+| `text` | string | yes | The text to type. |
+| `target` | object | no | If given, this node is clicked first (to focus it) before typing. |
+
+**Result:** `{ "ok": true }`.
+
+**Errors:** if `target` is supplied, the same actionability errors as
+`input.click` apply (`1001` / `1002`).
+
+### `input.key`
+
+Send a key chord (a key plus optional modifiers) to the focused window.
+
+**Params:**
+
+| Param | Type | Required | Meaning |
+|---|---|---|---|
+| `keys` | string or array | yes | Either a `"+"`-joined string like `"ctrl+s"`, or an array like `["ctrl", "s"]`. The last token is the key; earlier tokens are modifiers. |
+
+**Result:** `{ "ok": true }`.
+
+**Key names must be lowercase.** Recognized key names include `"enter"`, `"tab"`,
+`"esc"`, `"space"`, `"delete"`, `"backspace"`, `"f5"` (and other function keys),
+and single characters (e.g. `"s"`, `"a"`). Recognized modifiers are `"ctrl"`,
+`"shift"`, `"alt"`, `"cmd"` (with `"meta"` as an alias for `"cmd"`).
+**Unrecognized or uppercase key names are silently ignored** — no error is
+returned, the key simply does not fire. Use lowercase names exclusively.
+
+### `sync.wait_for`
+
+Poll the UI until a target node reaches a desired state, or time out. This is the
+preferred way to synchronize with asynchronous UI changes (it replaces fragile
+fixed sleeps). Internally it repeatedly refreshes and dumps the tree, re-resolves
+the target, and evaluates the requested state until it is satisfied.
+
+**Params:**
+
+| Param | Type | Default | Meaning |
+|---|---|---|---|
+| `target` | object | required | Target spec. |
+| `state` | string | required | One of `"exists"`, `"visible"`, `"enabled"`, `"value"`. |
+| `value` | string | — | Required when `state` is `"value"`; the expected value to match. |
+| `timeout_ms` | int | `5000` | Maximum time to wait, in milliseconds. |
+| `poll_ms` | int | `100` | Poll interval, in milliseconds (minimum 1). |
+
+State semantics:
+
+- `exists` — the target resolves to a node.
+- `visible` — the node exists and is visible.
+- `enabled` — the node exists and is **both enabled and visible**.
+- `value` — the node has a value and that value equals the supplied `value`.
+
+**Result:** `{ "ok": true, "elapsed_ms": <int> }`.
+
+**Errors:** `1003` on timeout (the state was not reached within `timeout_ms`).
+
+### `app.state`
+
+Return a high-level application-state snapshot. Takes no parameters.
+
+**Result:**
+
+```json
+{
+  "active_tab": "<string>",
+  "project_loaded": <bool>,
+  "slicing": <bool>,
+  "slice_progress": <int>,
+  "foreground": <bool>,
+  "modal_dialog": "<string>"
+}
+```
+
+| Field | Meaning |
+|---|---|
+| `active_tab` | The active top-level tab/page. |
+| `project_loaded` | Whether a project/model is currently loaded. |
+| `slicing` | Whether slicing is currently in progress. |
+| `slice_progress` | Slicing progress (`-1` when unknown). |
+| `foreground` | Whether the main window is in the foreground. |
+| `modal_dialog` | Present only when a modal dialog is active; identifies it. Omitted otherwise. |
+
+### `screenshot.window`
+
+Capture a window as a PNG, exactly as it appears on screen.
+
+**Params:**
+
+| Param | Type | Default | Meaning |
+|---|---|---|---|
+| `target` | object | main frame | If given, capture this window; otherwise capture the main frame. |
+
+**Result:** `{ "png_base64": "<base64 PNG>", "width": <int>, "height": <int> }`.
+
+**Errors:** `1005` on screenshot failure; `1001` if a supplied `target` is not
+found or ambiguous.
+
+**How it works:** the window's on-screen rectangle is read back from the
+DWM-composited desktop framebuffer (`wxScreenDC`), so the capture includes every
+native child control, the OpenGL 3D viewport, and ImGui overlays — it is a faithful
+image of what the user sees. (Capturing the parent window's own client DC instead
+would clip out child HWNDs and the GL surface, leaving them black; that is why this
+method reads from the screen.)
+
+**Caveats:**
+
+- The window must be **visible and unobscured**. Because the source is the on-screen
+  framebuffer, any overlapping window occludes the captured region. The backend
+  raises the target window before capturing.
+- **HiDPI:** the reported `width`/`height` come from the window's logical client size,
+  while the screen framebuffer is in physical pixels. On per-monitor-DPI displays the
+  two can differ; the capture may be cropped or scaled relative to the logical size.
+- Because the capture is the live on-screen image, the 3D content reflects the
+  **current view**: the model in the 3D editor, or the gcode toolpaths in Preview
+  after a slice. There is no separate offscreen 3D-render method — the window
+  capture already includes whatever the GL canvas is showing.
+
+### `file.open`
+
+Load one or more files into the **already-running** instance at runtime, by calling
+`Plater::load_files(...)` directly on the GUI thread. This is the supported way to add
+or swap a model without relaunching the process. Loading is **synchronous**: when the
+call returns `ok: true`, `app.state().project_loaded` is already `true` (no polling
+race).
+
+**Params:**
+
+| Param | Type | Required | Meaning |
+|---|---|---|---|
+| `paths` | string or array of strings | yes | One or more **absolute** file paths. A bare string is accepted and treated as a one-element list. Paths are read from the **host (server) filesystem** — client and server are localhost-only. |
+
+`.3mf` files are routed as projects and meshes as models automatically, based on file
+content (the same default strategy as drag-drop); there is no `as_project` flag in v1.
+
+**Result:** `{ "ok": true, "loaded": <int> }`, where `loaded` is the number of objects
+added to the scene (`load_files(...).size()`).
+
+**Errors:**
+
+- `-32602` (invalid params) — `paths` is missing, is not a string/array, contains a
+  non-string entry, or yields no non-empty path.
+- `1007` (load failed) — `load_files` returned empty or threw (file not found, parse
+  error, or unsupported format).
+- `1004` (GUI busy) — the GUI-thread marshal timed out. An extremely large model can
+  exceed the marshal timeout and surface here; documented, not mitigated in v1.
+
+### `view.select`
+
+Switch the main window to a top-level view/tab at runtime. Useful to put the UI in a
+known state before other actions — e.g. switch to **Prepare** before loading a model,
+or to **Preview** after slicing.
+
+**Params:**
+
+| Param | Type | Required | Meaning |
+|---|---|---|---|
+| `view` | string | yes | The target view. One of: `home`, `prepare` (3D editor), `preview` (sliced G-code), `device`, `multi_device`, `project`, `calibration`. |
+
+**Result:** `{ "ok": true, "view": <string>, "index": <int> }`, where `index` is the
+resulting tab index (it can vary with layout, since some tabs — e.g. `multi_device` —
+are only present in certain configurations).
+
+**Errors:**
+
+- `-32602` (invalid params) — `view` is missing, is not a string, or is empty.
+- `1001` (not found) — the view name is unknown, or that view is not available in the
+  current layout (for example `prepare`/`preview` in G-code-viewer mode, or
+  `multi_device` when multi-device is disabled).
+- `1004` (GUI busy) — the GUI-thread marshal timed out.
+

+
+## 5. Unified node shape
+
+Both wx widgets and ImGui items are reported with the same node schema:
+
+```json
+{
+  "backend": "wx" | "imgui",
+  "id": "<string>",
+  "path": "<string>",
+  "class": "<string>",
+  "label": "<string>",
+  "rect": { "x": <int>, "y": <int>, "w": <int>, "h": <int> },
+  "enabled": <bool>,
+  "visible": <bool>,
+  "value": "<string>",
+  "children": [ <node>, ... ]
+}
+```
+
+| Field | Meaning |
+|---|---|
+| `backend` | `"wx"` for native wxWidgets controls, `"imgui"` for immediate-mode ImGui items. |
+| `id` | The automation id when one is set, otherwise a derived id. For ImGui items the `path` doubles as the `id`. |
+| `path` | Positional path, e.g. `"MainFrame/Panel[2]/Button[0]"`. For ImGui items: `"ImGui/<window>/<label>"`. |
+| `class` | wx class name, or the ImGui item type. |
+| `label` | The control's label/caption. May include an ImGui `##`-id suffix for ImGui items. |
+| `rect` | Bounding rectangle in **screen coordinates**. |
+| `enabled` | Whether the control is enabled. |
+| `visible` | Whether the control is visible. |
+| `value` | The control's value (text/choice/check/slider, etc.). **Omitted entirely** when the control has no applicable value. |
+| `children` | Child nodes. **wx only**, and present only when children are included (e.g. `tree.dump`, `widget.get`). ImGui items are flat (no children) and are listed under their window. |
+
+Notes:
+
+- The `value` key is **omitted** (not `null`) when the control has no value.
+- `children` is present only for wx nodes when children are requested; ImGui nodes
+  never carry `children`.
+
+---
+
+## 6. Target / locator
+
+Most methods accept a **target** object that identifies one or more nodes. A
+target may specify:
+
+| Field | Meaning |
+|---|---|
+| `id` | Exact automation id. |
+| `path` | Exact positional path. |
+| `name` | Predicate: matches either the node's `id` **or** its `label`. |
+| `class` | Predicate: exact class name. |
+| `label` | Predicate: exact label. |
+| `value` | Predicate: node has a value and it equals this string. |
+| `backend` | Predicate: `"wx"` or `"imgui"`. |
+
+**Resolution order:** **`id` → `path` → predicate.**
+
+- If `id` is present, only `id` is used (exact match).
+- Else if `path` is present, only `path` is used (exact match).
+- Else the predicate fields (`name`, `class`, `label`, `value`, `backend`) are
+  used, and all provided predicate fields are **ANDed** together.
+
+Action methods (`input.click`, `input.type` with a target, `widget.get`, and
+single-target `screenshot.window`) require a **unique** match. If the target
+resolves to zero matches or more than one match, the call fails with error `1001`
+(not found / ambiguous). `tree.find` is the exception: it returns *all* matches as
+an array and never errors on ambiguity.
+
+---
+
+## 7. Error codes
+
+Standard JSON-RPC codes:
+
+| Code | Meaning |
+|---|---|
+| `-32700` | Parse error — the request body was not valid JSON. |
+| `-32600` | Invalid request — missing/invalid `method`. |
+| `-32601` | Method not found — unknown method name. |
+| `-32602` | Invalid params — missing/invalid parameters for the method. |
+
+Application-specific codes:
+
+| Code | Meaning |
+|---|---|
+| `1001` | Widget/target not found **or** ambiguous (more than one match). |
+| `1002` | Not actionable — the target is disabled or hidden. |
+| `1003` | Wait timeout — `sync.wait_for` did not reach the requested state in time. |
+| `1004` | GUI thread busy / timeout — a backend call could not be marshaled onto the GUI thread in time (wedged GUI). |
+| `1005` | Screenshot failed. |
+| `1006` | Disabled. |
+| `1007` | Load failed — `file.open`'s `load_files` returned empty or threw (not found, parse error, unsupported format). |
+
+---
+
+## 8. Automation-id naming conventions & instrumented ids
+
+Stable automation ids follow these prefix conventions:
+
+| Prefix | Used for |
+|---|---|
+| `btn_` | Buttons |
+| `combo_` | Preset combo boxes |
+| `tab_` | Tabs |
+| `canvas_` | Canvases |
+| `dlg_` | Dialog buttons |
+
+### Instrumented ids (as-built in v1)
+
+The following controls currently carry stable automation ids:
+
+| id | Control | Note |
+|---|---|---|
+| `btn_slice` | Slice-plate button | |
+| `btn_export` | Print / Export button | Multi-purpose: the action (Print plate / Export G-code / Send) depends on the current mode. |
+| `tab_device` | Device / Monitor tab (`MonitorPanel`) | |
+| `combo_printer` | Printer preset combo (sidebar) | |
+| `combo_filament` | Filament preset combo (sidebar) | First filament row only; extra multi-material rows are not instrumented. |
+| `canvas_3d` | 3D editor GL canvas | |
+
+### Controls NOT instrumented in v1
+
+Several controls are intentionally **not** instrumented in v1 because they have no
+stable `wxWindow` target to attach an id to:
+
+- **`combo_process`** — process settings are not a sidebar combo box in the current
+  OrcaSlicer layout, so there is no combo control to instrument.
+- **`btn_add`** — the add/import-object control is a `GLToolbar` item rendered
+  *inside* the GL canvas, not a `wxWindow`.
+- **`tab_prepare` / `tab_preview`** — the Prepare and Preview notebook pages are
+  both backed by the **same** window, and the per-tab buttons are private; there is
+  no distinct stable window to target.
+
+For controls that are not instrumented, scripts should fall back to class / label /
+path lookup (for wx controls) or ImGui-item lookup (for ImGui controls).
+
+---
+
+## 9. ImGui notes
+
+ImGui is **immediate-mode**: an item is addressable only while it is being drawn in
+the current frame. The automation backend records ImGui items each frame, and a
+`refresh_ui` is forced before every read or action so that the latest frame's items
+are captured.
+
+Consequences and conventions:
+
+- Use [`sync.wait_for`](#syncwait_for) to wait for a transient gizmo or panel item
+  to appear before acting on it.
+- ImGui items are reported with `backend: "imgui"`, a `path` of the form
+  `ImGui/<window>/<label>`, and that **path doubles as the item's `id`** in v1.
+- ImGui items are **flat** — they have no `children` and are listed under their
+  window.
+- Labels may include ImGui `##`-id suffixes (the part after `##` that ImGui uses to
+  disambiguate identically labeled widgets).
+- Raw `ImGui::` gizmos that are *not* routed through the instrumented
+  `ImGuiWrapper` widgets (for example some Emboss / SVG / Text gizmo controls) are
+  only covered at the **window level** in v1; their individual sub-items are not
+  enumerated.
+
+---
+
+## 10. Platform & display caveats
+
+- **Input requires a focused, visible window.** OS-level input injection uses
+  `wxUIActionSimulator`, which requires a focused, visible window. The click path
+  raises and focuses the target's top-level window first.
+- **Linux CI needs a display.** There must be an X display available; wrap test
+  runs with `xvfb-run` (for example, `xvfb-run -a python example_slice.py ...`).
+- **Input is asynchronous.** Do **not** rely on fixed sleeps. Use
+  [`sync.wait_for`](#syncwait_for) — for example, wait for `btn_export` to become
+  `enabled` after slicing completes — rather than sleeping for a guessed duration.
+- **`screenshot.window` reads the screen.** It captures the on-screen, DWM-composited
+  framebuffer, so the target window must be visible and unobscured, and the result is
+  in physical pixels (see HiDPI caveat under [`screenshot.window`](#screenshotwindow)).
+  The capture includes the GL 3D viewport as currently shown (model or toolpaths).
+- **Single-client / serialized.** v1 handles one request at a time; issue requests
+  sequentially from a single client.
+- **GUI-thread marshaling.** Every backend call is marshaled onto the GUI thread
+  with a timeout. A wedged or unresponsive GUI returns error `1004`.
+
+---
+
+## 11. Quick start
+
+Using the reference client in `tools/automation/orca_automation.py`:
+
+```python
+from orca_automation import OrcaClient
+
+orca = OrcaClient(port=13619)
+print(orca.version())                       # {'version': '1.0.0', ...}
+
+orca.select_view("prepare")                 # switch to the 3D editor
+orca.open(r"C:\models\part.stl")            # load a model at runtime (synchronous)
+
+orca.click({"id": "btn_slice"})             # start slicing the plate
+orca.wait_for({"id": "btn_export"},         # wait until slicing finishes
+              state="enabled", timeout_ms=180000)
+
+orca.select_view("preview")                 # switch to the sliced G-code preview
+png = orca.screenshot()                     # on-screen capture (incl. 3D view)
+with open("window.png", "wb") as f:
+    f.write(png)
+```
+
+For a full, runnable end-to-end example — launching OrcaSlicer with the automation
+flags, loading a model, slicing, waiting for completion, and saving a window PNG —
+see `tools/automation/example_slice.py`.
+
+---
+
+## 12. Future work
+
+Planned enhancements beyond v1:
+
+- **Authentication token** plus a Preferences toggle to enable/disable the server
+  from the GUI.
+- **WebSocket push events** for real-time UI/state notifications (instead of
+  polling).
+- **Per-item ImGui gizmo instrumentation** so individual gizmo sub-controls (Emboss
+  / SVG / Text, etc.) are addressable, not just at the window level.
+- **More widget ids** — the process combo, the add/import button, and the
+  Prepare/Preview tabs once they expose stable windows.
+- An **MCP wrapper** to expose the automation surface to model-context tooling.
+
+---
+
+## Verification (v1)
+
+This section records the final regression gate for the v1 feature: confirmation
+that the protocol core is covered by unit tests, that the existing test suites
+are unaffected, and that the **disabled path (automation OFF, the default) is a
+true no-op** — zero new threads, zero socket binds, zero allocations, and zero
+behavior change.
+
+### Unit-suite results (Release, Windows / MSVC, Ninja Multi-Config)
+
+| Suite | Result |
+|---|---|
+| `automation` (protocol core) | **32 / 32 passed** |
+| `libslic3r` (most affected by the additive `PrintConfig.cpp` CLI options) | **99 / 99 passed** |
+| `fff_print` | **14 / 14 passed** |
+| `libnest2d` | **14 / 14 passed** |
+| `sla_print` | **21 / 21 passed** |
+| `slic3rutils` | 3 / 5 passed — 2 pre-existing `[OrcaCloudServiceAgent]` SEGFAULTs, **unrelated to automation** (see note) |
+
+> The two `slic3rutils` failures are `Orca cloud flat/nested session resolves
+> display name consistently`. They exercise `Slic3r::OrcaCloudServiceAgent`, which
+> the automation branch does **not** touch (verified via `git diff --stat
+> main...HEAD` — no change to `src/slic3r/Utils/OrcaCloudServiceAgent.*` or
+> `tests/slic3rutils/*`). They are pre-existing and not a regression introduced by
+> this feature.
+
+### Static disabled-path audit (the core regression guarantee)
+
+Verified by code reading that with no `--automation-server` flag:
+
+- **Flag defaults off.** `m_automation_port` defaults to `0`
+  (`src/slic3r/GUI/GUI_App.hpp:249`); `is_automation_enabled()` returns
+  `m_automation_port > 0` (`GUI_App.hpp:386`) → `false` by default.
+- **No server / thread / socket.** `post_init()` calls
+  `start_automation_server()` **only** when
+  `init_params->automation_port > 0` (`src/slic3r/GUI/GUI_App.cpp:737-740`), and
+  `start_automation_server()` itself early-returns when `m_automation_port <= 0`
+  (`GUI_App.cpp:7097`). The backend / dispatcher / beast server objects are
+  constructed nowhere else → no `orca_automation` thread and no localhost bind
+  when the flag is absent.
+- **Recording hooks short-circuit.** `ImGuiWrapper::automation_record_last_item`
+  has as its **first statement** `if (!wxGetApp().is_automation_enabled())
+  return;` (`src/slic3r/GUI/ImGuiWrapper.cpp:576-577`) — a single bool check, no
+  `ImGuiItemRecord` allocation and no `ImGuiItemTable` access on the disabled
+  path. In `ImGuiWrapper::render()` the window-enumeration loop and
+  `swap_frame()` are fully wrapped in `if (wxGetApp().is_automation_enabled())`
+  (`ImGuiWrapper.cpp:599-611`); when off, `render()` is its original
+  `ImGui::Render()` + `render_draw_data()` plus one bool check.
+- **Instrumentation is inert.** The ~7 `set_automation_id(...)` calls
+  (`MainFrame.cpp:1330,1389,1841,1842`; `Plater.cpp:1772,2172,5068`) only store a
+  pointer into a static registry and bind a `wxEVT_DESTROY` pruning handler
+  (`src/slic3r/GUI/Automation/AutomationRegistry.cpp:24-36`). The registry is
+  **read** only via `window_for_automation_id` / `automation_id_of`, which are
+  called solely by the backend while the server is running → harmless when off.
+- **CLI options are purely additive.** `automation_server` (coBool, default
+  `false`) and `automation_server_port` (coInt, default `13619`) are new `add()`
+  entries appended after `enable_timelapse`
+  (`src/libslic3r/PrintConfig.cpp:10794-10805`); no existing option is changed.
+  `GUI_InitParams::automation_port` defaults to `0`
+  (`src/slic3r/GUI/GUI_Init.hpp:37`) and is set only when `--automation-server`
+  is supplied (`src/OrcaSlicer.cpp:1345-1348`).
+
+**Conclusion:** with automation OFF (the default), the feature allocates nothing
+and changes nothing — the only added cost on any hot path is a single boolean
+comparison.
+
+### Deferred manual runtime checks (require a display / Xvfb)
+
+These need a live GUI and cannot be run headlessly in CI; they are the manual
+acceptance steps:
+
+1. Launch **without** `--automation-server` → `curl http://127.0.0.1:13619/`
+   fails to connect (no listener); no `orca_automation` thread exists.
+2. Launch **with** `--automation-server --automation-server-port=13619` →
+   `GET /` returns the health text; `POST /jsonrpc {"method":"automation.version"}`
+   returns version / protocol / capabilities; `widget.get {"target":{"id":"btn_slice"}}`
+   returns a node with a sensible screen rect.
+3. Interactive sanity: open a gizmo / move sliders with automation OFF → no
+   visual or behavior change.
+
+See `tools/automation/example_slice.py` for the runnable end-to-end path.

+# `file.open` Automation Method Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a `file.open` JSON-RPC automation method that loads one or more files into an already-running OrcaSlicer instance by calling `Plater::load_files(...)` synchronously on the GUI thread.
+
+**Architecture:** Follows the existing `screenshot.window` / `app.state` method pattern. A new pure-virtual `open_files(paths)` is added to the wx-free `IUiBackend` interface; `WxUiBackend` implements it via the existing `run_on_gui(...)` GUI-thread marshal calling `Plater::load_files`; the `JsonRpcDispatcher` gains a `file.open` route, a param-parsing helper, and a new `kErrLoadFailed = 1007` error code. The unit-testable surface (dispatcher + param validation + routing) is driven against `MockUiBackend`.
+
+**Tech Stack:** C++17, nlohmann::json, Catch2 v2 (`catch_all.hpp` / `Catch2WithMain`), wxWidgets, CMake + Ninja Multi-Config. Python 3 reference client (stdlib only).
+
+---
+
+## Design-spec note (resolve before coding)
+
+The design spec's error table reads `1002 | kInvalidParams | paths missing/empty…`, but in the codebase `kInvalidParams` is the standard JSON-RPC code **`-32602`**, while `1002` is `kErrNotActionable`. The spec's **Constant column (`kInvalidParams`) is authoritative** and matches every other param-validation path in the dispatcher (e.g. `m_input_type` throws `kInvalidParams` for a bad `text`). This plan therefore validates `file.open` params with **`kInvalidParams` (-32602)**, exactly like the existing handlers, and the tests assert `== kInvalidParams`. The literal "1002" in the spec is a typo; do not emit code 1002 for param errors.
+
+## File Structure
+
+| File | Change | Responsibility |
+|---|---|---|
+| `src/slic3r/GUI/Automation/IUiBackend.hpp` | modify | Add pure-virtual `int open_files(paths)` to the backend abstraction (stays wx-free). |
+| `src/slic3r/GUI/Automation/JsonRpcDispatcher.hpp` | modify | Add `kErrLoadFailed = 1007` constant + `m_file_open` declaration. |
+| `src/slic3r/GUI/Automation/JsonRpcDispatcher.cpp` | modify | Add `parse_paths` helper, `m_file_open` body, dispatch route, capabilities entry. |
+| `src/slic3r/GUI/Automation/WxUiBackend.hpp` | modify | Declare `open_files` override. |
+| `src/slic3r/GUI/Automation/WxUiBackend.cpp` | modify | Implement `open_files` via `run_on_gui` → `Plater::load_files`. |
+| `tests/automation/MockUiBackend.hpp` | modify | `open_files` override: record paths + return-count + fail knob. |
+| `tests/automation/test_dispatcher.cpp` | modify | Catch2 tests for routing, string/array, validation, failure, capabilities. |
+| `tools/automation/orca_automation.py` | modify | `open(self, paths)` client wrapper. |
+| `tools/automation/example_slice.py` | modify | Launch without a model arg, then `orca.open([model])`. |
+| `doc/automation.md` | modify | Document the method, capabilities, error `1007`. |
+
+**Build/test layout:** Ninja Multi-Config in `build/`. The unit suite target is `automation_tests`; its sources (`tests/automation/CMakeLists.txt`) compile `JsonRpcDispatcher.cpp` + `MockUiBackend` but **not** `WxUiBackend.cpp`. So dispatcher/mock changes are fully unit-testable headlessly; `WxUiBackend.cpp` is verified by the full app build only.
+
+---
+
+## Task 1: Extend the backend abstraction (interface + mock + error code)
+
+Adds the `open_files` contract so tests can be written. Adding a pure virtual to `IUiBackend` forces every implementation to provide it — in the unit-test target that is only `MockUiBackend`, so this task keeps the `automation_tests` build green.
+
+**Files:**
+- Modify: `src/slic3r/GUI/Automation/IUiBackend.hpp`
+- Modify: `src/slic3r/GUI/Automation/JsonRpcDispatcher.hpp:19`
+- Modify: `tests/automation/MockUiBackend.hpp`
+
+- [ ] **Step 1: Add the error constant**
+
+In `src/slic3r/GUI/Automation/JsonRpcDispatcher.hpp`, after the existing `kErrDisabled` line (currently line 19), add:
+
+```cpp
+constexpr int kErrDisabled        = 1006;
+constexpr int kErrLoadFailed      = 1007; // file.open: load_files returned empty / threw
+```
+
+- [ ] **Step 2: Add the pure-virtual `open_files` to the interface**
+
+In `src/slic3r/GUI/Automation/IUiBackend.hpp`, inside `class IUiBackend`, immediately after the `screenshot_window` pure virtual (currently line 97), add:
+
+```cpp
+    // Load one or more files (absolute paths) into the running instance on the GUI
+    // thread. Returns the number of objects added to the scene (load_files(...).size()).
+    // Throws AutomationError(kErrLoadFailed) when nothing loads. Header stays wx-free:
+    // the concrete LoadStrategy is chosen inside WxUiBackend, not exposed here.
+    virtual int open_files(const std::vector<std::string>& paths) = 0;
+```
+
+- [ ] **Step 3: Implement `open_files` in the mock with record + knobs**
+
+In `tests/automation/MockUiBackend.hpp`: add an include for the error constant near the top (after the `IUiBackend.hpp` include on line 2):
+
+```cpp
+#include "slic3r/GUI/Automation/IUiBackend.hpp"
+#include "slic3r/GUI/Automation/JsonRpcDispatcher.hpp" // kErrLoadFailed
+```
+
+Add recorded-call + canned-output members. After the `screenshot_window_count` recorded field (line 20) add:
+
+```cpp
+    int               screenshot_window_count   = 0;
+    std::vector<std::vector<std::string>> opened_paths; // paths of each open_files()
+```
+
+After the `click_result` canned field (line 26) add:
+
+```cpp
+    bool     click_result = true;
+    int      open_return_count = 0;     // value open_files() returns
+    bool     open_should_fail = false;  // when true, open_files() throws kErrLoadFailed
+```
+
+Add the override next to the other overrides, after `screenshot_window` (lines 49-51):
+
+```cpp
+    PngImage screenshot_window(const UiNode*) override {
+        ++screenshot_window_count; return canned_png;
+    }
+    int      open_files(const std::vector<std::string>& paths) override {
+        opened_paths.push_back(paths);
+        if (open_should_fail)
+            throw AutomationError(kErrLoadFailed, "mock load failed");
+        return open_return_count;
+    }
+```
+
+- [ ] **Step 4: Build the unit-test target to confirm it still compiles**
+
+Run: `cmake --build build --config RelWithDebInfo --target automation_tests`
+Expected: build succeeds (the new pure virtual is satisfied by the mock; no behavior change yet).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/slic3r/GUI/Automation/IUiBackend.hpp src/slic3r/GUI/Automation/JsonRpcDispatcher.hpp tests/automation/MockUiBackend.hpp
+git commit -m "feat(automation): add open_files to backend interface + kErrLoadFailed (1007)"
+```
+
+---
+
+## Task 2: `file.open` dispatcher handler (parse, route, validate, fail)
+
+Implements the full JSON-RPC handler against the mock: param parsing (string or array), validation, routing to `open_files`, and `kErrLoadFailed` propagation.
+
+**Files:**
+- Modify: `src/slic3r/GUI/Automation/JsonRpcDispatcher.hpp:49` (declaration)
+- Modify: `src/slic3r/GUI/Automation/JsonRpcDispatcher.cpp`
+- Test: `tests/automation/test_dispatcher.cpp`
+
+- [ ] **Step 1: Write the failing happy-path test (array of paths)**
+
+Append to `tests/automation/test_dispatcher.cpp`:
+
+```cpp
+TEST_CASE("file.open with an array of paths routes to backend", "[automation][rpc]") {
+    MockUiBackend mock;
+    mock.open_return_count = 3;
+    JsonRpcDispatcher d(mock);
+    const json resp = d.dispatch({{"jsonrpc","2.0"},{"id",1},{"method","file.open"},
+        {"params",{{"paths", json::array({"C:/abs/a.stl","C:/abs/b.stl"})}}}});
+    CHECK(resp.at("result").at("ok") == true);
+    CHECK(resp.at("result").at("loaded") == 3);
+    REQUIRE(mock.opened_paths.size() == 1);
+    REQUIRE(mock.opened_paths[0].size() == 2);
+    CHECK(mock.opened_paths[0][0] == "C:/abs/a.stl");
+    CHECK(mock.opened_paths[0][1] == "C:/abs/b.stl");
+}
+```
+
+- [ ] **Step 2: Run the test to verify it fails**
+
+Run: `cmake --build build --config RelWithDebInfo --target automation_tests && build/tests/automation/RelWithDebInfo/automation_tests.exe "file.open with an array of paths routes to backend"`
+Expected: FAIL — `file.open` is an unknown method, so the response carries `error.code == -32601` and has no `result` (the `resp.at("result")` access throws). (If the exe path differs on your machine, locate it with `find build -iname automation_tests.exe`.)
+
+- [ ] **Step 3: Declare the handler**
+
+In `src/slic3r/GUI/Automation/JsonRpcDispatcher.hpp`, after the `m_screenshot_window` declaration (currently line 49) add:
+
+```cpp
+    nlohmann::json m_screenshot_window(const nlohmann::json& params);
+    nlohmann::json m_file_open(const nlohmann::json& params);
+```
+
+- [ ] **Step 4: Add the `parse_paths` helper and `m_file_open` body**
+
+In `src/slic3r/GUI/Automation/JsonRpcDispatcher.cpp`, add a `parse_paths` helper. Place it in the anonymous namespace that also holds `parse_keys` — insert it right before that namespace's closing `} // namespace` (currently line 130):
+
+```cpp
+// "paths" may be a single string ("C:/a.stl") or an array of strings. Returns the
+// non-empty absolute paths; throws kInvalidParams when paths is missing, not a
+// string/array, contains a non-string entry, or yields no non-empty path.
+std::vector<std::string> parse_paths(const nlohmann::json& params) {
+    if (!params.is_object() || !params.contains("paths"))
+        throw AutomationError(kInvalidParams, "file.open requires 'paths'");
+    const auto& p = params.at("paths");
+    std::vector<std::string> out;
+    if (p.is_string()) {
+        out.push_back(p.get<std::string>());
+    } else if (p.is_array()) {
+        for (const auto& e : p) {

+
+(`<algorithm>` for `std::remove_if` is already included at the top of the file, line 4.)
+
+Add the handler body next to the other handlers. After `m_screenshot_window` (currently ends line 343, just before the final `}}} // namespace`), add:
+
+```cpp
+nlohmann::json JsonRpcDispatcher::m_file_open(const nlohmann::json& params) {
+    const std::vector<std::string> paths = parse_paths(params);
+    const int loaded = m_backend.open_files(paths);
+    return { {"ok", true}, {"loaded", loaded} };
+}
+```
+
+- [ ] **Step 5: Add the dispatch route**
+
+In `JsonRpcDispatcher::dispatch`, after the `screenshot.window` route (currently line 195) add:
+
+```cpp
+        if (method == "screenshot.window")         return make_result(id, m_screenshot_window(params));

+## Task 3: Advertise `file.open` in `automation.version` capabilities
+
+**Files:**
+- Modify: `src/slic3r/GUI/Automation/JsonRpcDispatcher.cpp:166-172`
+- Test: `tests/automation/test_dispatcher.cpp`
+
+- [ ] **Step 1: Write the failing capabilities test**
+
+Append to `tests/automation/test_dispatcher.cpp`:
+
+```cpp

+
+- [ ] **Step 2: Run the test to verify it fails**
+
+Run: `cmake --build build --config RelWithDebInfo --target automation_tests && build/tests/automation/RelWithDebInfo/automation_tests.exe "automation.version capabilities include file.open"`
+Expected: FAIL — `CHECK(found)` is false; `file.open` is not yet in the capabilities array.
+
+- [ ] **Step 3: Add `file.open` to the capabilities array**
+
+In `JsonRpcDispatcher::m_version` (currently lines 166-172), add `"file.open"` to the array:

+## Task 4: Implement `WxUiBackend::open_files` (real GUI-thread load)
+
+Not covered by the headless unit suite (`WxUiBackend.cpp` is excluded from `automation_tests`); verified by the full app build + the manual runtime check in Task 8.
+
+**Files:**
+- Modify: `src/slic3r/GUI/Automation/WxUiBackend.hpp:21`
+- Modify: `src/slic3r/GUI/Automation/WxUiBackend.cpp`
+
+- [ ] **Step 1: Declare the override**
+
+In `src/slic3r/GUI/Automation/WxUiBackend.hpp`, after the `screenshot_window` declaration (line 21) add:
+
+```cpp
+    PngImage screenshot_window(const UiNode* target) override;
+    int      open_files(const std::vector<std::string>& paths) override;
+```
+
+- [ ] **Step 2: Implement `open_files`**
+
+In `src/slic3r/GUI/Automation/WxUiBackend.cpp`, add the implementation just before the final `}}} // namespace Slic3r::GUI::Automation` (currently line 306):
+
+```cpp
+int WxUiBackend::open_files(const std::vector<std::string>& paths) {
+    return run_on_gui(m_gui_timeout_ms, [&]() -> int {
+        Plater* plater = wxGetApp().plater();
+        if (plater == nullptr)
+            throw AutomationError(kErrLoadFailed, "no plater to load into");
+        // Default strategy matches drag-drop / Plater::load_files's own default: it
+        // routes .3mf as a project and meshes as models based on file content, so no
+        // as_project flag is needed in v1. ask_multi=false: never prompt.
+        const LoadStrategy strategy = LoadStrategy::LoadModel | LoadStrategy::LoadConfig;
+        std::vector<size_t> loaded;
+        try {
+            loaded = plater->load_files(paths, strategy, /*ask_multi=*/false);
+        } catch (const std::exception& e) {
+            throw AutomationError(kErrLoadFailed,
+                                  std::string("load_files failed: ") + e.what());
+        }
+        if (loaded.empty())
+            throw AutomationError(kErrLoadFailed, "load_files loaded nothing");
+        return static_cast<int>(loaded.size());
+    });
+}
+```
+
+Notes for the implementer:
+- `LoadStrategy` and its `operator|` (namespace `Slic3r`, from `libslic3r/Format/bbs_3mf.hpp`) are already in scope: `WxUiBackend.cpp` includes `Plater.hpp` (line 7), which transitively pulls in the enum, and this translation unit lives in `Slic3r::GUI::Automation` so unqualified `LoadStrategy` resolves via the enclosing `Slic3r` namespace. No new include is required.
+- `Plater::load_files(const std::vector<std::string>&, LoadStrategy, bool)` is the existing string overload (`Plater.hpp:379`) — no `boost::filesystem::path` conversion needed.
+- `kErrLoadFailed` comes from `JsonRpcDispatcher.hpp`, already included at line 4.
+- An `AutomationError` thrown inside the `run_on_gui` lambda is captured by the helper's `set_exception` and rethrown from `fut.get()`, so the 1007 code propagates to the dispatcher unchanged.
+
+- [ ] **Step 3: Build the full app to verify it compiles and links**
+
+Run: `cmake --build build --config RelWithDebInfo --target OrcaSlicer`
+Expected: build succeeds (no missing-symbol / pure-virtual errors; `WxUiBackend` is now concrete).

+
+**Files:**
+- Modify: `tools/automation/orca_automation.py:80-82`
+
+- [ ] **Step 1: Add the `open` method**
+
+In `tools/automation/orca_automation.py`, after the `key` method (ends line 82), add:
+
+```python
+    def key(self, keys) -> dict:
+        # keys: "ctrl+s" or ["ctrl", "s"]

+
+    def open(self, paths) -> dict:
+        """Load one or more files into the running instance at runtime.
+
+        `paths` is a single absolute path string or a list of them. Paths are read
+        from the host filesystem by the server (localhost-only). Returns
+        {"ok": True, "loaded": <count>}. Raises OrcaError 1007 on load failure."""
+        if isinstance(paths, str):
+            paths = [paths]
+        return self._call("file.open", {"paths": list(paths)})
+```
+
+- [ ] **Step 2: Smoke-test the wrapper's normalization offline (no server needed)**
+
+Run:
+```bash
+python -c "import sys; sys.path.insert(0, 'tools/automation'); import orca_automation as m; c = m.OrcaClient.__new__(m.OrcaClient); c._call = lambda meth, params=None: (meth, params); print(c.open('C:/a.stl')); print(c.open(['C:/a.stl','C:/b.stl']))"
+```
+Expected output:
+```
+('file.open', {'paths': ['C:/a.stl']})
+('file.open', {'paths': ['C:/a.stl', 'C:/b.stl']})

+
+## Task 6: Update `example_slice.py` to load at runtime via `file.open`
+
+**Files:**
+- Modify: `tools/automation/example_slice.py:26-52`
+
+- [ ] **Step 1: Launch without the model arg, then call `open`**
+
+In `tools/automation/example_slice.py`, change the `subprocess.Popen` call (lines 26-31) to drop the trailing model positional:
+
+```python
+    proc = subprocess.Popen([
+        args.orca,
+        "--automation-server",
+        f"--automation-server-port={args.port}",
+    ])
+```
+
+Then replace the project-load wait block (currently lines 46-51) so the model is loaded at runtime via `file.open` instead of relying on a launch-time positional:
+
+```python
+        # Load the model into the already-running instance, then wait until the
+        # project reports loaded. file.open is synchronous, so project_loaded is
+        # already true on return; the wait is a belt-and-suspenders guard.
+        orca.open([args.model])
+        deadline = time.time() + 30
+        while time.time() < deadline:
+            if orca.app_state().get("project_loaded"):
+                break
+            time.sleep(0.5)
+```
+
+- [ ] **Step 2: Byte-compile the script to confirm no syntax errors**
+
+Run: `python -m py_compile tools/automation/example_slice.py`
+Expected: no output, exit code 0.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add tools/automation/example_slice.py
+git commit -m "docs(automation): example_slice.py loads model at runtime via file.open"
+```
+
+---
+
+## Task 7: Document `file.open` in `doc/automation.md`
+
+**Files:**
+- Modify: `doc/automation.md` (capabilities example §4 line 111-114; new method subsection after `screenshot.window`; error table §7)
+
+- [ ] **Step 1: Add `file.open` to the capabilities example**
+
+In `doc/automation.md`, update the `automation.version` result example (lines 111-114) to include `file.open`:
+
+```json
+  "capabilities": [
+    "tree.dump", "tree.find", "widget.get", "input.click", "input.type",
+    "input.key", "sync.wait_for", "app.state", "screenshot.window", "file.open"
+  ]
+```
+
+The §4 prose count is already written for this: "There are 11 methods … the 10 callable feature methods" now matches exactly (10 capability entries + `automation.version` = 11). Leave that sentence unchanged.
+
+- [ ] **Step 2: Add the `file.open` method subsection**
+
+In `doc/automation.md`, immediately after the `screenshot.window` method subsection (it ends just before the `---` on line 303) and before that `---`, insert:
+
+```markdown
+### `file.open`
+
+Load one or more files into the **already-running** instance at runtime, by calling
+`Plater::load_files(...)` directly on the GUI thread. This is the supported way to add
+or swap a model without relaunching the process. Loading is **synchronous**: when the
+call returns `ok: true`, `app.state().project_loaded` is already `true` (no polling
+race).
+
+**Params:**
+
+| Param | Type | Required | Meaning |
+|---|---|---|---|
+| `paths` | string or array of strings | yes | One or more **absolute** file paths. A bare string is accepted and treated as a one-element list. Paths are read from the **host (server) filesystem** — client and server are localhost-only. |
+
+`.3mf` files are routed as projects and meshes as models automatically, based on file
+content (the same default strategy as drag-drop); there is no `as_project` flag in v1.
+
+**Result:** `{ "ok": true, "loaded": <int> }`, where `loaded` is the number of objects
+added to the scene (`load_files(...).size()`).
+
+**Errors:**
+
+- `-32602` (invalid params) — `paths` is missing, is not a string/array, contains a
+  non-string entry, or yields no non-empty path.
+- `1007` (load failed) — `load_files` returned empty or threw (file not found, parse
+  error, or unsupported format).
+- `1004` (GUI busy) — the GUI-thread marshal timed out. An extremely large model can
+  exceed the marshal timeout and surface here; documented, not mitigated in v1.
+```
+
+- [ ] **Step 3: Add the `1007` row to the error-code table**
+
+In `doc/automation.md` §7, in the application-specific codes table, after the `1006` row (line 395) add:
+
+```markdown
+| `1006` | Disabled. |
+| `1007` | Load failed — `file.open`'s `load_files` returned empty or threw (not found, parse error, unsupported format). |
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add doc/automation.md
+git commit -m "docs(automation): document file.open method and error 1007"
+```
+
+---
+
+## Final verification
+
+- [ ] **Step 1: Full automation unit suite green**
+
+Run: `cmake --build build --config RelWithDebInfo --target automation_tests && build/tests/automation/RelWithDebInfo/automation_tests.exe --order rand --warn NoAssertions`
+Expected: PASS — all cases (pre-existing ~32 + 7 new) green, no `NoAssertions` warnings on the new cases.
+
+- [ ] **Step 2: Full app builds**
+
+Run: `cmake --build build --config RelWithDebInfo --target ALL_BUILD -- -m`
+Expected: build succeeds.
+
+- [ ] **Step 3: Manual runtime check (requires a display)**
+
+Launch with `--automation-server` and **no** model arg, then from a Python shell:
+```python
+from orca_automation import OrcaClient
+orca = OrcaClient(port=13619)
+print(orca.open(["C:/abs/path/cube.stl"]))   # -> {'ok': True, 'loaded': 1}
+print(orca.app_state()["project_loaded"])    # -> True
+open("window.png","wb").write(orca.screenshot())  # PNG shows the loaded model
+```
+Expected: `loaded >= 1`, `project_loaded == True`, screenshot shows the model.
+
+- [ ] **Step 4: Gating check (automation OFF is a no-op)**
+
+Confirm by reading: with no `--automation-server` flag, the server/backend/dispatcher are never constructed (`GUI_App.cpp` `start_automation_server()` early-return), so `file.open` is unreachable. No new hot-path cost beyond the existing single bool check. (See `doc/automation.md` §Verification — disabled-path audit; this feature adds no new gating surface.)
+
+---
+
+## Backward compatibility
+
+Additive only: one new method (`file.open`), one new error code (`1007`), one new capabilities entry, and one new backend interface method. No existing method, profile, project-file handling, or default behavior changes. The method is reachable only when `--automation-server` is passed.

+# Design — `file.open` automation method (runtime model loading)
+
+**Date:** 2026-06-03
+**Branch:** `feature/automation`
+**Status:** Approved for implementation
+
+---
+
+## Problem
+
+Today a model can be loaded into OrcaSlicer **only at process launch**: the model path
+is passed as a CLI positional arg and OrcaSlicer's normal startup file-loading ingests
+it. The JSON-RPC automation protocol has **no** load method, so swapping or adding a
+model in an already-running instance requires a fresh process launch.
+
+Driving the native File→Import dialog via `input.click` is not a viable substitute: the
+OS file picker is not a `wxWindow`, so it never appears in the `tree.dump` hierarchy
+(`WxUiBackend::dump_tree` walks `wxGetApp().mainframe` children only), and `input.click`
+can only target nodes resolved from that tree (no raw-coordinate click). Blind typing via
+`input.type` is mechanically possible but unobservable: the native picker is not a
+`wxDialog`, so `app.state().modal_dialog` and `sync.wait_for` cannot gate on it, leaving
+only sleep-and-hope timing. A direct API method is the clean fix.
+
+## Goal
+
+Add a `file.open` JSON-RPC method that loads one or more files into a running instance by
+calling `Plater::load_files(...)` directly on the GUI thread. Out of scope: any
+dialog-driving mechanism (intercept hook or true OS-level drive) — explicitly deferred.
+
+---
+
+## Protocol
+
+- **Method:** `file.open`
+- **Params:** `{ "paths": ["C:/abs/a.stl", ...] }`
+  - A bare string is also accepted: `{ "paths": "C:/abs/a.stl" }`.
+  - Paths must be **absolute**. The server reads them from the host filesystem
+    (client/server are localhost-only).
+- **Result:** `{ "ok": true, "loaded": <count> }`
+  - `count` is `load_files(...).size()` — the number of objects added to the scene.
+- **Errors:**
+  | Code | Constant | Condition |
+  |------|----------|-----------|
+  | -32602 | `kInvalidParams` | `paths` missing/empty, a non-string entry, or no non-empty path |
+  | 1004 | `kErrGuiBusy` | GUI-thread marshal timed out (`m_gui_timeout_ms`) |
+  | 1007 | `kErrLoadFailed` | `load_files` returned empty / threw (not found, parse error, unsupported format) — **new code** |
+
+## Semantics — synchronous
+
+`Plater::load_files` runs and completes on the GUI thread. The backend marshals via the
+existing `run_on_gui(m_gui_timeout_ms, …)` helper and returns only after the load
+finishes. Consequently, when `file.open` returns `ok:true`, `app.state().project_loaded`
+is already `true` — there is no polling race.
+
+Rejected alternative — async "fire-and-poll-`project_loaded`": adds client complexity and
+loses a definitive per-call error result, with no benefit since loading is synchronous.
+
+**Caveat:** an extremely large model could exceed `m_gui_timeout_ms` and surface as
+`1004 kErrGuiBusy`. Documented; not mitigated in v1.
+
+## Load strategy (v1 minimal)
+
+Pass the default `LoadStrategy::LoadModel | LoadStrategy::LoadConfig` (identical to
+drag-drop / `Plater::load_files`'s default) with `ask_multi = false`. This already routes
+`.3mf` files as projects and meshes as models based on file content, so **no `as_project`
+flag is needed in v1**. A future `{ "as_project": bool }` flag remains possible but is not
+implemented now.
+
+---
+
+## Components / files to touch
+
+Follows the existing `screenshot_window` / `app_state` method pattern.
+
+1. **`src/slic3r/GUI/Automation/IUiBackend.hpp`** — add pure-virtual
+   `int open_files(const std::vector<std::string>& paths)` returning the loaded count,
+   throwing `AutomationError` on failure. Header stays wx-free (no `LoadStrategy` leak).
+2. **`src/slic3r/GUI/Automation/WxUiBackend.{hpp,cpp}`** — implement `open_files`:
+   `run_on_gui(m_gui_timeout_ms, …)` → `wxGetApp().plater()->load_files(paths, default_strategy, false)`;
+   throw `kErrLoadFailed` if the returned vector is empty.
+3. **`src/slic3r/GUI/Automation/JsonRpcDispatcher.{hpp,cpp}`** —
+   - add `constexpr int kErrLoadFailed = 1007;`
+   - declare + define `m_file_open(params)` (param parsing/validation; accept string or
+     array; require ≥1 non-empty string path)
+   - add dispatch route `if (method == "file.open") return make_result(id, m_file_open(params));`
+   - add `"file.open"` to the capabilities array in `m_version`.
+4. **`tests/automation/MockUiBackend.hpp`** — `open_files` override recording the paths
+   vector + a configurable return-count (and a throw/fail knob).
+5. **`tests/automation/test_dispatcher.cpp`** — Catch2 v2 tests:
+   - array of paths → routes to backend, returns `loaded` count
+   - bare-string path → normalized to one path
+   - missing/empty `paths` → `-32602` (`kInvalidParams`)
+   - backend load failure → `1007`
+   - `automation.version` capabilities array includes `"file.open"`
+6. **`tools/automation/orca_automation.py`** — `open(self, paths)` wrapper (normalize
+   `str` → `[str]`, send `file.open`).
+7. **`tools/automation/example_slice.py`** — launch **without** a model arg, then
+   `orca.open([model])`, then wait for `project_loaded`.
+8. **`doc/automation.md`** — document method (params/result/errors), add to the
+   capabilities list, method index, and error table (`1007`).
+
+---
+
+## Testing / verification
+
+- **Build (Windows):** `cmake --build . --config RelWithDebInfo --target ALL_BUILD -- -m`.
+- **Unit:** `automation` Catch2 suite green including new tests (≈31 → ≈34 cases).
+- **Manual:** launch with `--automation-server` and **no** model arg → call `file.open`
+  → confirm `app.state().project_loaded` flips `true` and `screenshot.window` shows the
+  model.
+- **Gating:** unchanged — the server only runs under `--automation-server`, so the method
+  is a no-op (unreachable) when automation is disabled.
+
+## Backward compatibility
+
+Additive only: a new method, a new error code, and a new capabilities entry. No change to
+existing methods, profiles, project-file handling, or default behavior.

+# OrcaSlicer UI Automation — Design Spec
+
+**Date:** 2026-06-03
+**Status:** Approved design, pending implementation plan
+**Topic:** Add an opt-in, externally-controllable UI automation interface to OrcaSlicer for automated GUI testing and future AI-agent control.
+
+---
+
+## 1. Overview
+
+Add a localhost JSON-RPC server to a running OrcaSlicer GUI instance that lets an
+**external** script (or AI agent) drive and observe the real GUI. "Driving" is done
+the way a user would — simulated mouse/keyboard via `wxUIActionSimulator` — while
+"observing" reads the live widget state and captures screenshots.
+
+The interface must cover **three UI technologies** present in OrcaSlicer:
+
+1. Native **wxWidgets** widgets (`wxWindow` hierarchy).
+2. The **OpenGL 3D viewport** (`GLCanvas3D`) — screenshots via the existing
+   framebuffer/thumbnail path.
+3. **Dear ImGui** immediate-mode controls (gizmo panels, in-canvas overlays,
+   notifications) — recorded as they are drawn, because there is no persistent tree.
+
+## 2. Goals / Non-Goals
+
+### Goals
+- Let an external, language-agnostic client connect to a running instance and:
+  introspect the UI, locate widgets by stable name, perform input actions, wait on
+  conditions, and capture screenshots (including the 3D view as a separate image).
+- Be safe by default: disabled unless explicitly enabled; bound to `127.0.0.1` only.
+- Be testable in CI without a display (pure-logic units behind a mock backend).
+- Ship a reference Python client, a runnable end-to-end example, protocol docs, and
+  C++ unit tests.
+
+### Non-Goals (v1)
+- No headless/offscreen automation — OS input injection needs a focused, visible
+  window (Linux CI requires a display, e.g. Xvfb).
+- No auth token in v1 (documented future hardening; localhost-only is the boundary).
+- No per-item coverage of raw-`ImGui::` gizmos (Emboss/SVG/Text). They get
+  window-level coverage; per-item is future work.
+- No new scripting language embedded in the app; control is purely external over JSON-RPC.
+- We do **not** modify the existing auth `HttpServer`.
+
+## 3. Background — existing infrastructure (verified)
+
+- **`wxUIActionSimulator`** is compiled into the wx build and already used
+  (`src/slic3r/GUI/GUI_ObjectList.cpp:211`). Cross-platform simulated input is available.
+- **`GLCanvas3D::render_thumbnail()`** (`src/slic3r/GUI/GLCanvas3D.cpp:2210+`) →
+  `render_thumbnail_framebuffer()` (`:6352`) renders the 3D scene into a
+  `ThumbnailData` (RGBA) via an FBO + `glReadPixels`. `debug_output_thumbnail()`
+  (`:6099`) shows the `ThumbnailData → wxImage → PNG` conversion. This is the
+  separate-3D-screenshot path. `Plater::generate_thumbnail()`/`generate_thumbnails()`
+  wrap it.
+- **`ImGuiWrapper`** (`src/slic3r/GUI/ImGuiWrapper.hpp`) is the chokepoint for nearly
+  all ImGui controls: `button`/`bbl_button`, `checkbox`/`bbl_checkbox`, `combo`,
+  `slider_float`, `input_double`, `radio_button`, `menu_item_with_icon`, plus
+  `begin`/`end` for windows. `imgui_internal.h` is in-tree, exposing
+  `ImGui::GetCurrentContext()->Windows`, item rects, and hovered/active id.
+- **`HttpServer`** (`src/slic3r/GUI/HttpServer.{hpp,cpp}`, boost::beast, port 13618)
+  is used for cloud auth. **It cannot serve a POST body** — `session::read_body()`
+  reads and discards the body and never replies (`HttpServer.cpp:57-65`). It is
+  effectively GET-only. We will **not** reuse or modify it.
+- **`OtherInstanceMessageHandler`** (`src/slic3r/GUI/InstanceCheck.{hpp,cpp}`) is the
+  template for "start a localhost listener once the MainFrame exists, post events into
+  the GUI." Useful as a structural reference.
+- **CLI args** are parsed in `src/OrcaSlicer.cpp` (`CLI::setup`/`CLI::run`) and flow
+  into the GUI run params consumed by `GUI_App::OnInit()`.
+
+## 4. Architecture
+
+```
+External script / AI agent  ──►  Python client (orca_automation.py)
+        │  HTTP POST /jsonrpc   (JSON-RPC 2.0)   on 127.0.0.1:<port>
+        ▼
+AutomationServer            (dedicated boost::beast listener; own thread;
+        │                    started only when --automation-server is set)
+        │  parse JSON-RPC envelope
+        ▼
+JsonRpcDispatcher           (pure logic — method registry; unit-testable)
+        │  marshal each call to the GUI thread via wxGetApp().CallAfter
+        │  + std::promise/future with a per-request timeout
+        ▼
+IUiBackend (interface)  ──►  WxUiBackend (real, GUI thread)   /   MockBackend (tests)
+        ├─ Introspection : walk wxWindow tree + read ImGui item table → unified JSON
+        ├─ Locator       : resolve automation-id / predicate → wx widget or ImGui item
+        ├─ Actions       : raise window, then wxUIActionSimulator click/type/key
+        ├─ Sync          : wait_for (poll condition) + app.state snapshot
+        └─ Screenshots   : wx widget → wxDC→PNG ;  3D view → render_thumbnail()→PNG
+```
+
+### Components (new files unless noted)
+
+All new code lives under `src/slic3r/GUI/Automation/`.
+
+| Component | Responsibility |
+|---|---|
+| `AutomationServer.{hpp,cpp}` | Dedicated boost::beast HTTP listener with **POST + body** support; one `POST /jsonrpc` endpoint; returns `application/json`. Localhost-only. Own thread. |
+| `JsonRpcDispatcher.{hpp,cpp}` | Parse JSON-RPC 2.0; route `method` → handler; build result/error. Depends only on `IUiBackend`. No wx/ImGui includes → unit-testable. |
+| `IUiBackend.hpp` | Abstract interface: `dump_tree`, `find`, `get_widget`, `click`, `type`, `key`, `wait_for`, `app_state`, `screenshot_window`, `screenshot_viewport3d`. Uses plain structs (no wx types) so tests can mock it. |
+| `WxUiBackend.{hpp,cpp}` | Real implementation. Runs on GUI thread. Walks `wxWindow` tree, reads the ImGui item table, drives `wxUIActionSimulator`, captures screenshots. |
+| `MockUiBackend.{hpp,cpp}` (tests) | Deterministic fake tree + recorded actions for unit tests. |
+| `AutomationRegistry.{hpp,cpp}` | Process-wide `wxWindow* → automation_id` map + reverse lookup; `set_automation_id(win, "id")` helper. Header is dependency-light so widget-construction code can call the helper unconditionally (it is a cheap no-op-safe registration). |
+| `WidgetSerializer.{hpp,cpp}` | `wxWindow` → JSON node (name/id, class, label, screen-rect, enabled, shown, value via RTTI). |
+| `ImGuiItemTable.{hpp,cpp}` | Per-frame recorder of ImGui items + live-window enumeration. Populated from `ImGuiWrapper`; read on GUI thread. |
+
+### Touch points in existing files
+- `src/slic3r/GUI/ImGuiWrapper.cpp` — add recording hooks inside the wrapped widget
+  methods and `begin`/`end`, **guarded by an `is_automation_enabled()` flag** so there
+  is zero overhead and zero behavior change when automation is off.
+- `src/slic3r/GUI/GUI_App.{hpp,cpp}` — own the `AutomationServer`; start it in
+  `OnInit()` only when the flag is set; stop it on exit. Expose
+  `is_automation_enabled()`.
+- `src/OrcaSlicer.cpp` — parse `--automation-server[=PORT]`; pass through GUI run params.
+- A handful of widget-construction sites (Slice/Export buttons, preset combos, main
+  tabs, common dialog OK/Cancel, the 3D canvas) — add `set_automation_id(...)` calls
+  (~15-20 widgets in v1).
+- CMake: add the new `Automation/` sources to the GUI target; add the unit-test target.
+
+## 5. Transport & Protocol
+
+- **Transport:** HTTP/1.1 on `127.0.0.1:<port>` (default **13619**, adjacent to the
+  auth server's 13618). Single endpoint: `POST /jsonrpc`, body is a JSON-RPC 2.0
+  request, response is a JSON-RPC 2.0 result/error. `GET /` returns a tiny health/version page.
+- **Protocol:** JSON-RPC 2.0. `id`, `method`, `params`. Batch not required in v1.
+
+### v1 methods
+
+| Method | Params | Result |
+|---|---|---|
+| `automation.version` | — | `{version, protocol, capabilities[]}` |
+| `tree.dump` | `{root?, max_depth?, visible_only?, include_imgui?}` | tree of nodes (wx + imgui) |
+| `tree.find` | `{name?, class?, label?, value?, backend?}` | `[node...]` matches |
+| `widget.get` | `{target}` | single node detail |
+| `input.click` | `{target, button?=left, double?=false, modifiers?[]}` | `{ok}` |
+| `input.type` | `{target?, text}` | `{ok}` |
+| `input.key` | `{keys}` e.g. `"ctrl+s"` or `["ctrl","s"]` | `{ok}` |
+| `sync.wait_for` | `{target, state: exists\|visible\|enabled\|value, value?, timeout_ms?=5000, poll_ms?=100}` | `{ok, elapsed_ms}` |
+| `app.state` | — | `{active_tab, project_loaded, slicing, slice_progress, modal_dialog?, foreground}` |
+| `screenshot.window` | `{target?}` (default main frame) | `{png_base64, width, height}` |
+| `screenshot.viewport3d` | `{plate?, width?, height?}` | `{png_base64, width, height}` |
+
+### Node shape (unified for wx and ImGui)
+```json
+{
+  "backend": "wx" | "imgui",
+  "id": "btn_slice",                 // automation id if set, else derived path id
+  "path": "MainFrame/.../btn_slice", // stable-ish positional path
+  "class": "Button",                 // wx class name or imgui item type
+  "label": "Slice plate",
+  "rect": { "x": 100, "y": 200, "w": 120, "h": 32 },  // screen coords
+  "enabled": true,
+  "visible": true,
+  "value": "PLA",                    // when applicable (text/choice/check/slider)
+  "children": [ ... ]                // wx only; imgui items are flat under their window
+}
+```
+
+### Error model (JSON-RPC `error.code`)
+- `-32700` parse error, `-32601` method not found, `-32602` invalid params (standard).
+- Application codes: `1001` widget/target not found, `1002` target not actionable
+  (disabled/hidden), `1003` wait timeout, `1004` GUI thread busy/timeout,
+  `1005` screenshot failed, `1006` automation feature disabled.
+
+## 6. Threading model
+
+- `AutomationServer` runs on its own thread and accepts connections; the dispatcher
+  parses on that thread.
+- **Every** call touching wx/ImGui/GL is marshaled to the GUI thread with
+  `wxGetApp().CallAfter([...]{ ... })`; the server thread blocks on a `std::future`
+  with a per-request timeout (default 5 s; `wait_for` uses its own larger budget).
+  Timeout → error `1004`.
+- This is mandatory: wx widgets, the ImGui context, and the GL context are not
+  thread-safe and are owned by the GUI thread.
+- `CallAfter` is serviced even while modal dialogs run (nested event loop), so
+  automation can interact with dialogs.
+
+## 7. Widget locator & automation IDs (wxWidgets)
+
+- **Stable IDs:** `set_automation_id(window, "btn_slice")` registers the widget in
+  `AutomationRegistry`. Stored in a side map keyed by `wxWindow*` (not via `SetName`,
+  to avoid any coupling with wx's name-based lookups). Registration is removed on
+  widget destruction (bind to `wxEVT_DESTROY` or prune lazily on lookup).
+- **Derived IDs:** for un-instrumented widgets, `WidgetSerializer` derives a positional
+  `path` (e.g. `MainFrame/Panel[2]/Button[0]`) so an AI agent can still target anything.
+  Named IDs are the preferred, stable path.
+- **Locator resolution order:** exact automation id → exact path → predicate match
+  (name/class/label/value). Ambiguous matches return the list via `tree.find`; action
+  methods require a unique match or error `1001`.
+- **v1 instrumented widgets (~15-20):** Slice/Export buttons, printer & filament preset
+  combos, the main tab buttons (`tp3DEditor`/`tpPreview`/`tpMonitor`/…), Add/Import,
+  common dialog OK/Cancel/Yes/No, the `GLCanvas3D` itself.
+
+## 8. ImGui coverage (v1 = wrapper items + window introspection)
+
+- **Item recording:** inside each `ImGuiWrapper` wrapped method, when
+  `is_automation_enabled()` is true, append the just-drawn item to a per-frame
+  `ImGuiItemTable` entry: `{window_name, label/id, type, rect, enabled, value}`.
+  Item rect comes from `ImGui::GetItemRectMin/Max()` (ImGui display coords) mapped to
+  **screen** coords via the `GLCanvas3D` client origin (`ClientToScreen`) and DPI scale.
+- **Window enumeration:** via `imgui_internal.h`, enumerate `GetCurrentContext()->Windows`
+  for window name, rect, visibility, plus the global hovered/active item id.
+- **Double-buffering:** the table is swapped at frame end (`ImGuiWrapper::render`) so
+  readers see a complete frame. Reads happen on the GUI thread (after marshaling), same
+  thread as rendering, so a simple front/back swap suffices.
+- **Freshness:** because items exist only while drawn, before an ImGui tree read or
+  action the backend forces a canvas refresh and flushes events so the latest frame is
+  captured. `sync.wait_for` can poll for an ImGui item to appear (e.g. after opening a
+  gizmo).
+- **Actions:** an ImGui target resolves to its recorded screen rect; `input.click`/
+  `input.type` use `wxUIActionSimulator` on that rect — identical action path to wx,
+  different rect source. Typing into an ImGui input works because simulated keystrokes
+  flow through the existing `ImGuiWrapper::update_key_data` bridge once the field is
+  focused by a click.
+- **Limitation (documented):** raw-`ImGui::` gizmos (Emboss, SVG, Text) are covered at
+  the **window** level only in v1; per-item instrumentation is future work.
+
+## 9. Screenshots
+
+- **`screenshot.window`:** capture a `wxWindow` (default: main frame) via
+  `wxClientDC`/`wxWindowDC` → `wxBitmap` → `wxImage` → PNG → base64. Works for native
+  widgets but **not** for the GL canvas region (returns black there) — hence the
+  separate 3D method.
+- **`screenshot.viewport3d`:** reuse `GLCanvas3D::render_thumbnail()` (FBO +
+  `glReadPixels`) → `ThumbnailData` → `wxImage` (per `debug_output_thumbnail`) → PNG →
+  base64. Optional `plate`, `width`, `height` params. Runs on the GUI thread with the GL
+  context current.
+
+## 10. Activation & security
+
+- **Off by default.** Enabled by CLI flag `--automation-server[=PORT]` (default port
+  13619). (An app-config/Preferences toggle may be added later; v1 is flag-only.)
+- **Bind `127.0.0.1` only.** No external interface.
+- **No token in v1** (per decision); documented as a recommended future hardening,
+  along with an optional `--automation-token`.
+- When disabled: no listener, no thread, and all `ImGuiWrapper` recording hooks are
+  skipped — **zero** runtime overhead and **zero** behavior change. This satisfies the
+  project's "features gated by options must not affect existing behavior when disabled"
+  constraint.
+
+## 11. Testability
+
+- `JsonRpcDispatcher` depends only on `IUiBackend` and has **no** wx/ImGui/GL includes.
+- **C++ unit tests (Catch2), display-free, run in CI:**
+  - JSON-RPC envelope parse/validate/dispatch (good + malformed input, error codes).
+  - Method routing and param validation for every v1 method against `MockUiBackend`.
+  - `WidgetSerializer` node shape (fed a synthetic node model, not real wx widgets).
+  - Locator resolution: exact id, path, predicate, ambiguity, not-found.
+- The only piece needing a real GUI is `WxUiBackend`; it is exercised by the manual
+  end-to-end example, not by CI unit tests.
+
+## 12. Deliverables
+
+- **C++:** the `Automation/` components, `ImGuiWrapper` recording hooks, widget
+  instrumentation, CLI flag plumbing, `GUI_App` lifecycle, CMake wiring.
+- **`tools/automation/orca_automation.py`:** reference Python client wrapping the
+  JSON-RPC calls (`connect`, `version`, `dump_tree`, `find`, `click`, `type`, `key`,
+  `wait_for`, `app_state`, `screenshot`, `screenshot_3d`).
+- **`tools/automation/example_slice.py`:** runnable end-to-end flow — launch OrcaSlicer
+  with the flag, load a model, click Slice, `wait_for` completion, save a 3D-preview PNG.
+  Doubles as a manual smoke test.
+- **`doc/automation.md`:** protocol reference (methods, params, results, error codes),
+  node shape, automation-id naming conventions, ImGui notes, platform/display caveats.
+- **`tests/`:** Catch2 unit-test target for the dispatch/serialize/locator logic.
+
+## 13. New / changed file inventory
+
+**New**
+- `src/slic3r/GUI/Automation/AutomationServer.{hpp,cpp}`
+- `src/slic3r/GUI/Automation/JsonRpcDispatcher.{hpp,cpp}`
+- `src/slic3r/GUI/Automation/IUiBackend.hpp`
+- `src/slic3r/GUI/Automation/WxUiBackend.{hpp,cpp}`
+- `src/slic3r/GUI/Automation/AutomationRegistry.{hpp,cpp}`
+- `src/slic3r/GUI/Automation/WidgetSerializer.{hpp,cpp}`
+- `src/slic3r/GUI/Automation/ImGuiItemTable.{hpp,cpp}`
+- `tools/automation/orca_automation.py`
+- `tools/automation/example_slice.py`
+- `doc/automation.md`
+- `tests/automation/` (Catch2 target) + `MockUiBackend.{hpp,cpp}`
+
+**Changed**
+- `src/slic3r/GUI/ImGuiWrapper.cpp` (guarded recording hooks)
+- `src/slic3r/GUI/GUI_App.{hpp,cpp}` (server lifecycle, `is_automation_enabled()`)
+- `src/OrcaSlicer.cpp` (CLI flag)
+- ~15-20 widget-construction sites (`set_automation_id`)
+- `src/slic3r/GUI/CMakeLists.txt` + `tests/CMakeLists.txt`
+
+## 14. Known constraints & limitations
+
+- OS input injection requires the OrcaSlicer window **focused and visible**; the backend
+  raises/focuses the main window before injecting. Linux CI needs a display (Xvfb).
+- Input is asynchronous at the OS level; correctness relies on `sync.wait_for` rather
+  than fixed sleeps.
+- ImGui items are only addressable while their host panel is drawn.
+- Raw-`ImGui::` gizmos: window-level only in v1.
+- Single-client assumption in v1 (serialized request handling); no concurrent sessions
+  contract.
+
+## 15. Future work (out of scope for v1)
+
+- Optional auth token + Preferences toggle.
+- WebSocket channel for server-push events (slice progress, dialog-appeared).
+- Per-item instrumentation for raw-`ImGui::` gizmos.
+- An MCP server wrapping the JSON-RPC client for direct AI-agent integration.
+- Optional integration of Dear ImGui Test Engine for deterministic ImGui interaction.
+
+## 16. Verification plan
+
+- **CI:** Catch2 unit tests (dispatch/serialize/locator) pass with no display.
+- **Manual / e2e:** run `tools/automation/example_slice.py` against a built OrcaSlicer
+  launched with `--automation-server`; confirm model loads, Slice runs, `wait_for`
+  returns on completion, and both a wx-window PNG and a 3D-viewport PNG are produced.
+- **Regression:** build and run with automation **off**; confirm no new threads, no
+  listener, and ImGui rendering is byte-for-byte unchanged (hooks compiled out of the
+  hot path via the disabled flag).
