+### Snap Store
+
+OrcaSlicer is available from the Snap Store:
+
+[![Get it from the Snap Store](https://snapcraft.io/static/images/badges/en/snap-store-black.svg)](https://snapcraft.io/orcaslicer)
+
+```shell
+sudo snap install orcaslicer --classic
+```
+
+Use a different channel for pre-releases or bleeding-edge builds:
+
+```shell
+sudo snap install orcaslicer --classic --candidate # release candidates (vX.Y.Z-rc)
+sudo snap install orcaslicer --classic --beta      # alpha / beta pre-releases
+sudo snap install orcaslicer --classic --edge      # nightly builds
+```
+
+The snap uses classic confinement, so it has full hardware and filesystem access just like the
+AppImage — including USB/serial printers, removable media, network shares, and 3D mice
+(3Dconnexion SpaceMouse via `spacenavd`). No extra setup is required after install.
+
 ### AppImage

+AppImages are published for both **x86_64** and **aarch64** (ARM64). Pick the file matching your CPU — the ARM64 build has `aarch64` in its name (e.g. `OrcaSlicer_Linux_AppImage_Ubuntu2404_aarch64_*.AppImage`).
+
 1. Download App image from the [releases page](https://github.com/OrcaSlicer/OrcaSlicer/releases).
 2. Double click the downloaded file to run it.

-# 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) {
-            if (!e.is_string())
-                throw AutomationError(kInvalidParams, "'paths' entries must be strings");
-            out.push_back(e.get<std::string>());
-        }
-    } else {
-        throw AutomationError(kInvalidParams, "'paths' must be a string or array");
-    }
-    out.erase(std::remove_if(out.begin(), out.end(),
-                             [](const std::string& s) { return s.empty(); }),
-              out.end());
-    if (out.empty())
-        throw AutomationError(kInvalidParams, "'paths' is empty");
-    return out;
-}
-```
-
-(`<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));
-        if (method == "file.open")                 return make_result(id, m_file_open(params));
-```
-
- [ ] **Step 6: Run the happy-path test to verify it passes**
-
-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: PASS — 1 test case, all assertions passed.
-
- [ ] **Step 7: Add the remaining handler tests (string, validation, failure)**
-
-Append to `tests/automation/test_dispatcher.cpp`:
-
-```cpp
-TEST_CASE("file.open accepts a bare string path", "[automation][rpc]") {
-    MockUiBackend mock;
-    mock.open_return_count = 1;
-    JsonRpcDispatcher d(mock);
-    const json resp = d.dispatch({{"jsonrpc","2.0"},{"id",2},{"method","file.open"},
-        {"params",{{"paths","C:/abs/a.stl"}}}});
-    CHECK(resp.at("result").at("loaded") == 1);
-    REQUIRE(mock.opened_paths.size() == 1);
-    REQUIRE(mock.opened_paths[0].size() == 1);
-    CHECK(mock.opened_paths[0][0] == "C:/abs/a.stl");
-}
-
-TEST_CASE("file.open with missing paths -> invalid params", "[automation][rpc]") {
-    MockUiBackend mock;
-    JsonRpcDispatcher d(mock);
-    const json resp = d.dispatch({{"jsonrpc","2.0"},{"id",3},{"method","file.open"},
-        {"params", json::object()}});
-    CHECK(resp.at("error").at("code") == kInvalidParams);
-    CHECK(mock.opened_paths.empty());
-}
-
-TEST_CASE("file.open with empty paths array -> invalid params", "[automation][rpc]") {
-    MockUiBackend mock;
-    JsonRpcDispatcher d(mock);
-    const json resp = d.dispatch({{"jsonrpc","2.0"},{"id",4},{"method","file.open"},
-        {"params",{{"paths", json::array()}}}});
-    CHECK(resp.at("error").at("code") == kInvalidParams);
-    CHECK(mock.opened_paths.empty());
-}
-
-TEST_CASE("file.open with a non-string entry -> invalid params", "[automation][rpc]") {
-    MockUiBackend mock;
-    JsonRpcDispatcher d(mock);
-    const json resp = d.dispatch({{"jsonrpc","2.0"},{"id",5},{"method","file.open"},
-        {"params",{{"paths", json::array({"C:/a.stl", 42})}}}});
-    CHECK(resp.at("error").at("code") == kInvalidParams);
-    CHECK(mock.opened_paths.empty());
-}
-
-TEST_CASE("file.open backend load failure -> 1007", "[automation][rpc]") {
-    MockUiBackend mock;
-    mock.open_should_fail = true;
-    JsonRpcDispatcher d(mock);
-    const json resp = d.dispatch({{"jsonrpc","2.0"},{"id",6},{"method","file.open"},
-        {"params",{{"paths","C:/abs/a.stl"}}}});
-    CHECK(resp.at("error").at("code") == kErrLoadFailed);
-}
-```
-
- [ ] **Step 8: Run all file.open tests to verify they pass**
-
-Run: `cmake --build build --config RelWithDebInfo --target automation_tests && build/tests/automation/RelWithDebInfo/automation_tests.exe "file.open*"`
-Expected: PASS — 6 test cases, all assertions passed.
-
- [ ] **Step 9: Commit**
-
-```bash
-git add src/slic3r/GUI/Automation/JsonRpcDispatcher.hpp src/slic3r/GUI/Automation/JsonRpcDispatcher.cpp tests/automation/test_dispatcher.cpp

-## 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
-TEST_CASE("automation.version capabilities include file.open", "[automation][rpc]") {
-    MockUiBackend mock;
-    JsonRpcDispatcher d(mock);
-    const json resp = d.dispatch({{"jsonrpc","2.0"},{"id",1},{"method","automation.version"}});
-    const auto& caps = resp.at("result").at("capabilities");
-    bool found = false;
-    for (const auto& c : caps) if (c == "file.open") found = true;
-    CHECK(found);
-}
-```
-
- [ ] **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:
-
-```cpp
-nlohmann::json JsonRpcDispatcher::m_version(const nlohmann::json&) {
-    return { {"version", kAutomationVersion},
-             {"protocol", "2.0"},
-             {"capabilities", nlohmann::json::array({
-                 "tree.dump","tree.find","widget.get","input.click","input.type",
-                 "input.key","sync.wait_for","app.state","screenshot.window",
-                 "file.open" })} };
-}
-```
-
- [ ] **Step 4: Run the test to verify it passes**
-
-Run: `cmake --build build --config RelWithDebInfo --target automation_tests && build/tests/automation/RelWithDebInfo/automation_tests.exe "automation.version capabilities include file.open"`
-Expected: PASS.
-
- [ ] **Step 5: Run the whole automation suite to confirm no regressions**
-
-Run: `cmake --build build --config RelWithDebInfo --target automation_tests && build/tests/automation/RelWithDebInfo/automation_tests.exe --order rand --warn NoAssertions`
-Expected: PASS — all cases green (the pre-existing ~32 plus the 7 new `file.open`/capabilities cases ≈ 39).
-
- [ ] **Step 6: Commit**
-

-## 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).
-
- [ ] **Step 4: Commit**
-
-```bash
-git add src/slic3r/GUI/Automation/WxUiBackend.hpp src/slic3r/GUI/Automation/WxUiBackend.cpp
-git commit -m "feat(automation): implement WxUiBackend::open_files via Plater::load_files"

-## Task 5: Python client wrapper `OrcaClient.open`
-
-**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"]
-        return self._call("input.key", {"keys": keys})
-
-    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']})
-```
-
- [ ] **Step 3: Commit**
-
-```bash
-git add tools/automation/orca_automation.py
-git commit -m "feat(automation): add OrcaClient.open() wrapper for file.open"

-## 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). |

-## 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.

-**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/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).
