 ## Localization & translations
 
-Catalogs live in `localization/i18n/<lang>/OrcaSlicer_<lang>.po`; the template is `OrcaSlicer.pot`.
-See the [Localization guide](https://github.com/OrcaSlicer/OrcaSlicer_WIKI/blob/main/guides/localization_guide.md) for the human-facing version of these principles.
-
-### Terminology
-
-- Use the [Localization glossary](https://github.com/OrcaSlicer/OrcaSlicer_WIKI/blob/main/guides/localization_glossary.md) as the source of truth for recurring terms, so the same English term is always rendered the same way within a language, and terms that must stay in English (brand/product names, acronyms, materials, file formats, G-code tokens, macros/variables/identifiers) are not translated.
-- If a term's established translation changes, update both the affected `.po` files and the glossary (`localization_glossary.tsv`, then regenerate) so they stay in sync.
-- Translate the *meaning*, not the words. Check what the string actually controls before translating it — English reuses one word for different things. `Flow ratio` (multiplier), `Flow Rate` (throughput) and `Flow Dynamics` (pressure compensation) are three different terms; `extruder` may mean the toolhead, the feeder motor, or the nozzle depending on the string.
-- Reuse one template per recurring message shape (`Failed to connect to …`, `Are you sure you want to …?`), even where the English wording varies.
-
-### Editing rules
-
-- Only edit `msgstr` — **never** change `msgid`, and never "fix" wrong English in the translation alone. Report the source string instead.
-- Preserve exactly: placeholders (`%s`, `%d`, `%1%`, `%zu`, `%%`), every `\n` (count *and* position, including leading/trailing), leading/trailing spaces, HTML tags, `℃`, and the file's encoding and line endings.
-- **Never reorder positional arguments** in a `c-format` string. If the msgid is `%d` then `%s`, that order must hold — swapping them breaks at runtime.
-- `msgctxt` separates homonyms — always read it. `Back`/`Camera View` is the rear view of the 3D navigator, while `Back`/`Navigation` is the go-back button; `Top` exists in the *Alignment*, *Layers* and *Camera View* senses.
-- When a string needs disambiguating, add context in the source (`_L_CONTEXT`/`_u8L_CONTEXT`), don't work around it in the translation.
-- A literal `%` inside a string xgettext flagged `possible-c-format` will fail `msgfmt`. Fix it with a `// xgettext:no-c-format, no-boost-format` comment above the string in the source — do not mangle the translation or use `%%` in text that is never passed through printf.
-- Plural entries: read `nplurals` from the catalog's `Plural-Forms` header (it is **not** always 2 — ja/ko/zh/th/vi use 1, ru/cs/pl/lt use 3, uk uses 4). Each form must be genuinely inflected for its quantity; repeating one sentence across all forms is a bug in Slavic/Baltic languages, though it is correct for Turkish and Hungarian.
-- An entry whose `msgstr` equals its `msgid` is untranslated even though it is not empty; a plural entry with any empty form is likewise incomplete.
-- Mark machine-produced translations with an `# AI Translated` translator comment. Don't add it to a human translation you didn't actually rewrite.
-- Don't reflow or re-wrap unrelated entries — keep the diff limited to the strings you changed.
-
-### Verifying
-
-- `scripts/run_gettext.bat --full` (Windows) regenerates the template, merges every catalog and compiles the `.mo` files. It must exit 0.
-- Or check a single catalog with `msgfmt --check-format -o <out>.mo localization/i18n/<lang>/OrcaSlicer_<lang>.po`.
-- Fuzzy entries are not shown to users. If you correct one, clear its `fuzzy` flag, otherwise the fix never ships.
+- Translation catalogs live in `localization/i18n/<lang>/OrcaSlicer_<lang>.po`.
+- When creating or reviewing translations, use the [Localization glossary](https://github.com/OrcaSlicer/OrcaSlicer_WIKI/blob/main/guides/localization_glossary.md) as the source of truth for recurring terms, so the same English term is always rendered the same way within a language and terms that must stay in English (brand/product names, acronyms, file formats, G-code, macros/variables) are not translated.
+- If a term's established translation changes, update both the affected `.po` files and the glossary so they stay in sync.

-The [nightly release](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/nightly-builds) ships **two parallel builds**: the standard build and a belt-printer build. Both are attached to the same release — tell them apart by the filename suffix:
-
-- **Standard** — no suffix (e.g. `OrcaSlicer_Windows_Installer_x64_nightly.exe`)
-- **Belt** — `_belt` suffix (e.g. `OrcaSlicer_Windows_Installer_x64_nightly_belt.exe`)
-
-The `_belt` builds add **experimental support for belt / conveyor (infinite-Z) printers**, where the model is sliced against a tilted belt surface instead of a flat horizontal bed. They include ready-to-use belt printer profiles, the full belt slicing pipeline (mesh rotation and G-code transforms), belt-aware support generation, and a tilted-bed preview.
-
-> ⚠️ Belt printer support is under active development and is **not yet merged into `main`** — it currently ships only in these parallel `_belt` builds, produced from the [`belt-printer`](https://github.com/OrcaSlicer/OrcaSlicer/tree/belt-printer) branch.

+# Texture Displacement - Technical Notes
+
+Branch: `feature/texture_displacement`. This document is a knowledge dump of the whole feature as
+it stands: architecture, file map, algorithms, known bugs found and fixed (with root causes worth
+remembering), and what's still deferred. Written so a fresh session (or a fresh pair of eyes) can
+pick this up without re-deriving everything from scratch.
+
+## What it does
+
+A paint-style gizmo (`GLGizmoTextureDisplacement`) that lets you:
+- Paint one or more "layers" onto a model's surface, each a height-map texture with its own
+  depth/tiling/rotation/offset/invert/tile-mode/projection-mode/blend-mode.
+- Pick a texture from a shipped library (`resources/textures/displacement/`) or import your own
+  (saved into `<data_dir>/textures/displacement/`, kept separate so app updates can't clobber it).
+- Combine overlapping layers with image-editor-style blend modes (Add/Subtract/Multiply/Divide).
+- Preview the true displaced result live, before baking (background job, not on the UI thread).
+- Optionally preview via a fast GPU bump-map shader instead (no real geometry movement, just
+  shading) for a lighter-weight alternative.
+- Bake into real mesh geometry on demand, restricted to the painted area only.
+- Subdivide a low-poly model first so there are enough vertices to show fine detail.
+- Unwrap a painted patch with a real CGAL LSCM parameterization and view it in a dedicated,
+  dockable 2D "UV Editor" pane.
+
+## Architecture
+
+### Data model (per `ModelVolume`)
+
+Each of up to `TEXTURE_DISPLACEMENT_MAX_LAYERS` (8) layers gets its **own independent
+`FacetsAnnotation`** paint mask - the exact same `TriangleSelector`/`FacetsAnnotation` machinery
+every other paint gizmo (FdmSupports, Seam, MMU, FuzzySkin) already uses, just one full instance
+per layer slot instead of one per volume. This is what makes "layered/blended" painting work for
+free: the same triangle can be `ENFORCER` in layer 2's mask and layer 5's mask simultaneously, and
+at bake/preview time each layer displaces the surface left by the previous one (image-editor-layer
+semantics).
+
+### Bake algorithm (`libslic3r/TextureDisplacement.cpp`)
+
+`build_texture_displacement(base_mesh, layers, facets_data, options)` is **accumulate-then-displace,
+and topology-preserving**: the returned mesh has exactly the input's vertices and triangles, in the
+same order - only the positions of displaced vertices differ.
+
+1. `its_compactify_vertices()` on a copy of the input. In practice a no-op (it only drops
+   *unreferenced* vertices, and preserves the order and indices of the rest). It is there to
+   guarantee the index alignment step 3 depends on.
+2. Area-weighted vertex normals of the **undisplaced** mesh, computed once. Every layer both
+   projects and displaces along these, so a vertex covered by several layers moves along one single
+   well-defined direction. Where the paint does *not* cover every triangle around a vertex, the normal
+   is recomputed from the painted triangles alone (the union over all layers, so it stays one direction
+   per vertex). On the rim of a fully painted top face the whole-mesh normal is the 45 degrees bisector
+   it shares with the side wall, and displacing along that flares the rim outwards instead of raising
+   it. Interior vertices are unaffected - all their triangles are painted, so the two coincide. Paint
+   coverage per original triangle comes straight off `TriangleSplittingData::triangles_to_split`.
+3. For each layer in slot order: deserialize its stored paint mask into a `TriangleSelector` against
+   the **base mesh** (never against a previous layer's output), then
+   `selector.get_facets_strict(ENFORCER)` → the painted patch. Two facts are exploited:
+   - `get_facets_strict()` returns the mesh's **entire** referenced vertex array regardless of which
+     state was asked for - only `.indices` is filtered by state. So `get_facets_strict(ENFORCER)`
+     and `get_facets_strict(NONE)` share identical vertex indexing, which is what lets boundary
+     detection be a plain index check instead of a position-hash lookup.
+   - The selector's vertex array *starts with* the mesh's own vertices (extra ones created where a
+     brush stroke split a triangle are appended after them), and `get_facets_strict()` emits the
+     referenced ones in order. Combined with step 1, **selector vertex index `i` is our vertex `i`**.
+     Split vertices live past the end of our array and are simply skipped - they sit on the paint
+     boundary anyway (splitting only happens at partial coverage), so they would be pinned regardless.
+4. A vertex used by at least one **unpainted** triangle is a border vertex. Whether it moves is
+   `TextureDisplacementOptions::displace_border`, and it **does by default**. The original design
+   pinned it, justified as stopping the patch tearing away from the surrounding surface - which stopped
+   being true the moment the bake became topology-preserving. There is no seam to tear: a border vertex
+   is *one* vertex shared by both regions, and moving it simply tilts the unpainted triangles that use
+   it. What pinning actually does is clamp the outermost ring of relief to zero, so on a fully painted
+   face the pattern collapses into a ring of steep ramps right at the edge - the reported "it doesn't
+   extrude at the border" artifact. Pinning is kept as an option for the case where the relief must not
+   spill past the paint at all. Either way the border still drives the `edge_smoothing` falloff.
+5. Per interior vertex: sample the height texture (`sample_layer_height()`, see Projection methods)
+   and fold `height * depth_mm * (invert ? -1 : 1)` into that vertex's running total via the layer's
+   `TextureBlendMode` (see Blend modes). A `visited` set makes each layer fold in exactly **once**
+   per vertex, no matter how many of the patch's triangles share it - otherwise a Multiply/Subtract
+   layer would apply two or three times over depending on local triangle fan-out.
+6. Finally, move each touched vertex along its (step 2) normal by its accumulated total.
+7. Optionally (`TextureDisplacementOptions::smooth_*`) relax the result - see Post-process smoothing.
+
+### Post-process smoothing
+
+`smooth_mesh_vertices(mesh, movable, strength, iterations)` - plain Laplacian relaxation, run after all
+layers have been folded in, restricted to the vertices flagged in `movable`. Each pass moves a movable
+vertex a `strength` fraction of the way to the average of its one-ring, read from a **snapshot** of the
+previous pass so the result does not depend on vertex order (a Gauss-Seidel sweep would smooth several
+times as hard at the end of the array as at the start). Neighbours come from a CSR-style adjacency built
+once per call.
+
+Its job is to round off the hard steps a bitmap height map leaves behind, which is a different knob from
+`TextureDisplacementLayer::smoothing` - that blurs the *height map* before it is ever sampled, this
+relaxes the *geometry* afterwards. Topology-preserving, like the bake.
+
+Two ways in, sharing one set of settings on the volume:
+- The **"Smooth result"** checkbox + "Smoothing (%)" / "Passes" ride along with Preview and Bake.
+  `movable` is exactly the set of vertices the displacement moved, so the untouched part of the model
+  keeps its exact geometry and the ring just outside the displaced set anchors the relaxation (the
+  relief cannot creep outward).
+- **"Smooth baked mesh now"** (`GLGizmoTextureDisplacement::smooth_model()`) applies the same settings to
+  the volume's *committed* geometry, for relief that is already baked in. `movable` there is the painted
+  triangles' vertices. Because smoothing never touches the triangle list, this is the one geometry
+  operation in the gizmo that keeps **every** paint channel verbatim - it saves and restores the eight
+  texture-displacement masks around `set_mesh()` rather than remapping or dropping them.
+
+**"Ignore outer ring"** (`smooth_skip_border`, **on by default**) drops the patch's own outermost ring of
+vertices from `movable`. That ring's neighbours *outside* the paint never move, so relaxing it drags the
+rim of the relief back down toward the flat surface and the pattern comes out half-melted exactly where
+it meets the edge - crisp everywhere else, which is what makes it look like a bug rather than a setting.
+Held out, the border keeps the full depth the texture asked for and only the interior relaxes. Turning it
+off softens the outer edge deliberately (a blunter version of the per-layer edge-smoothing falloff).
+Note this is the *smoothing* rim, a separate question from whether that rim is displaced at all
+(`displace_border`, step 4 above) - the two are independent and both default to "keep the border sharp".
+
+### Blend modes
+
+`TextureBlendMode` {Add, Subtract, Multiply, Divide}, per layer, applied per vertex against the
+total accumulated by the layers **below** it (lower slots). The quantity blended is a signed
+displacement in **mm**, not a pixel value.
+
+Add/Subtract are self-explanatory. Multiply/Divide are *scaling* operations and so need a unit
+convention: they treat the layer's own value as a **factor relative to 1 mm**. That makes `depth_mm`
+a gain, and - the property that makes a Multiply layer usable as a mask - a layer with depth 1 mm
+sampling a white (1.0) texel multiplies by exactly 1, i.e. leaves the layers below unchanged.
+Divide floors its divisor's magnitude at 0.05 - a black texel samples to *exactly* zero, so the
+divisor really does hit zero in ordinary use, and an unbounded `1/0` would fling vertices thousands
+of mm away and poison the mesh's bounding box (and every plate/print-volume check downstream). The
+floor doubles as a cap on how far Divide can amplify the relief beneath it: at most 20×.
+
+The **lowest painted layer ignores its blend mode**: it has nothing beneath it, and Multiply/Divide
+against an implicit zero base would annihilate (or blow up) it. Enforced in `build_texture_
+displacement()` (the first layer to reach a given vertex always folds in additively) and surfaced in
+the UI, which labels that layer "Base layer" instead of offering a control that silently does nothing.
+
+### Projection methods
+
+Four choices per layer (`TextureProjectionMethod`), all funneling through `apply_uv_transform()`
+(scale by `1/tiling_scale`, rotate by `rotation_deg`, add `offset`). They are dispatched by
+`sample_layer_height()`, which returns a **height**, not a UV - because Triplanar takes three
+texture samples per vertex and so has no single UV that represents it.
+
+- **Triplanar** (default) - samples the texture on all three world planes (`(y,z)`, `(x,z)`, `(x,y)`)
+  and blends the three by the vertex's own normal raised to `TRIPLANAR_BLEND_SHARPNESS` (4).
+  This is the fix for a real, user-reported bug. The previous version *hard-picked* the single axis
+  most aligned with the normal, which is discontinuous wherever that dominant axis flips: on a +X
+  face the planar coordinate is `(y, z)`, on a −Y face it is `(x, z)`, so at the shared edge `u`
+  jumps from `y_edge` to `x_edge`. On a box centred near the origin those two happen to **agree** at
+  the (+,+) and (−,−) corners and **differ by the full corner width** at the (+,−) and (−,+) corners
+  - which is exactly the "two bad corners, two good ones" symmetry that was observed. A weighted
+  blend is continuous across the transition by construction, since the weight of the axis being left
+  behind falls smoothly to zero. (Note this removes the hard *seam*; some cross-fade blurring in the
+  band right at a 90° edge is inherent to triplanar mapping. A genuinely seam-free wrap around a box
+  needs a real unwrap - that is what the LSCM mode is for.)
+- **Cylindrical** - wraps around an axis through the patch centroid, axis auto-picked as the world
+  axis *least* aligned with the average normal (perpendicular to the outward radial normal, as a
+  cylinder's own axis would be). `u = angle * local_radius` (arc length in mm), `v = distance along
+  axis`. Approximation, not an exact fit for arbitrary geometry.
+- **Spherical** - longitude/latitude around the centroid, scaled by local radius. Same caveat.
+- **LSCM** - real UV unwrap via `MeshBoolean::cgal::parameterize_lscm()` (CGAL's
+  `Surface_mesh_parameterization` package, LSCM algorithm). Computed **once per patch** (not
+  per-vertex like the others - it's a single global least-squares solve), then each vertex looks up
+  its precomputed UV. Requires the patch to be a single topological disk (one connected component,
+  one boundary loop) - `compute_lscm_uvs()` returns empty and the layer silently falls back to
+  Triplanar if not (e.g. multiple disconnected painted islands, or a fully closed patch).
+  CGAL's parameterizer needs a mesh with no isolated/unreferenced vertices, but `get_facets_strict()`
+  returns the *whole* mesh's vertex array - so there's a compaction step
+  (`compact_patch_with_map()`) that builds a clean sub-mesh + an index map back to the original
+  (uncompacted) vertex numbering, purely local to this file.
+- **ViewProjected** ("From view") - a flat projection along a fixed direction captured from the 3D
+  camera, like a slide projector. `capture_view_projection()` takes the camera's right/up axes,
+  transforms them into the volume's *local* frame (so the projection rides along if the part is later
+  moved), and stores them as `TextureDisplacementLayer::view_project_right/up` (unit vectors, so the
+  projected coordinate stays in mm and `tiling_scale` keeps meaning mm). `sample_layer_height()`
+  projects `Vec2f(dot(pos, right), dot(pos, up))`. Single-valued per point, so - like LSCM but unlike
+  blended Triplanar - the fast preview and UV-check overlay precompute it per vertex
+  (`compute_layer_vertex_uvs()`) and drive the shader's `use_vertex_uv` path. Faces angled away from
+  the projector smear; that is inherent to view projection, not a bug.
+
+  Two companions to this mode:
+  - **Projection frame overlay** (`TextureProjectorFrame`, see below) - a semi-transparent window
+    dragged over the 3D view whose border becomes the projection's edge. Applying it stores an exact
+    **projective** map in `view_project_matrix`, which supersedes the affine `right`/`up` axes above
+    for that layer (`view_project_projective`).
+  - **"Project only on visible"** (`select_visible_faces()`) - repaints the layer with exactly the
+    facets the camera can see, so the projected area matches the viewpoint the projector was captured
+    from. Two tests: a facing test (normal vs. view direction, per triangle - under perspective the
+    view direction varies across the model, so it is taken from the eye to each centroid), then
+    `MeshRaycaster::get_unobscured_idxs()` on the survivors to drop facets hidden behind other
+    geometry, so a concave part's far inner wall is correctly excluded. One ray query per front-facing
+    facet, hence click-driven (on the checkbox and on each "Capture current view"), never per frame.
+    It **replaces** the layer's paint rather than adding to it - "project onto what I can see" would
+    otherwise accumulate every angle the user had ever looked from.
+
+### Manual seams and island cutting
+
+`TextureDisplacementLayer::lscm_seam_edges` - undirected mesh-vertex-index edge pairs the unwrap is
+forced to cut along, on top of the dihedral-angle seams. `segment_into_charts()` takes a set of these
+(translated from mesh → compacted-patch numbering inside `compute_patch_unwrap()`) and refuses to
+union two triangles across a marked edge whatever their angle. Both the unwrap cache key and the
+gizmo's `UVEditorState` include the seam list, so marking a seam (which leaves the paint mask
+untouched) still forces a re-solve. Like the paint masks, seams are mesh-index-space and so dropped on
+any topology change.
+
+Two ways to write to it:
+- **Mark seam (manual, #9)** - a "Mark seams" click mode (`m_seam_edit_mode`) that suppresses
+  painting. A click raycasts the volume (`m_c->raycaster()->raycasters()[idx]->unproject_on_mesh()`,
+  `idx` = the volume's slot among model-part volumes), finds the facet's edge nearest the hit point,
+  and toggles it. Marked edges render as a red overlay (`render_seam_overlay()`), pulled toward the
+  camera so they read on top. This is the Blender mark-seam workflow.
+- **Cut island (auto, #17)** - `cut_island()` takes the selected chart's triangles (back-mapped from
+  the unwrap via `source_vertex`), finds their 3D bounding box, and marks every edge that straddles
+  the mid-plane perpendicular to the longest axis. The re-unwrap then splits the chart across its
+  narrow waist - the "islands might be very long" case. Exposed as the UV pane's **Cut** button.
+
+### UV-check overlays (checker / distortion)
+
+`resources/shaders/{110,140}/texture_displacement_uvcheck.{vs,fs}`, one shader with a `mode` uniform,
+drawn over the painted patch (`rebuild_uvcheck_mesh()`/`render_uvcheck_mesh()`, P3N3T2: `normal.x` =
+distortion, `tex_coord` = uv), pulled forward with a polygon offset. **Checker** (#13) samples a
+procedural checkerboard at the layer's uv (per-vertex for LSCM/ViewProjected, in-shader triplanar
+otherwise) - squares that stay square mean low distortion. **Distortion** (#14) colours each triangle
+blue→green→red by `log2(uv_area / surface_area)` centred on the patch's *median* stretch (so a
+globally-scaled unwrap reads as uniformly ideal and only relative stretch shows), averaged to
+vertices. A separate **Show mesh wireframe** toggle (#8) draws the whole volume's triangle edges,
+rebuilt only when the vertex count changes (not per stroke).
+
+### Tiling
+
+`DecodedHeightTexture::sample(uv, tile_enabled, tile_method)`. Two tile methods when enabled
+(Repeat, MirroredRepeat). **When `tile_enabled` is false, sampling outside `[0,1)` returns `0`
+directly** - clamping the *coordinate* into range (what an earlier version did) instead smears the
+border row/column of pixels outward to infinity in every direction, which is a real bug that was
+reported and fixed (visually: streaky lines radiating out from the painted patch).
+
+### Subdivision — two modes
+
+**Uniform (`subdivide_mesh_uniform()`)** — whole-mesh, 1-to-4 split. Recursive edge-midpoint split with
+a shared per-pass midpoint cache (keyed by sorted vertex-index pair) so triangles sharing an edge get
+the *same* new vertex - capped at `max_iterations` (default 6). Whole-mesh so it never leaves a
+T-junction, at the cost of densifying everywhere. Wired as a "Subdivide steps" slider (**0–5**, 0 =
+no subdivision), Apply snaps back to 0. Drops texture-displacement paint (no remap) via the standard
+`save_painting()`/`set_mesh()`/`restore_painting()` dance; the other four channels are remapped.
+
+**Adaptive (`subdivide_mesh_adaptive()`)** — refine **only the painted area**, by **Rivara longest-edge
+bisection**. This is the algorithm that was "scoped out" originally for fear of the T-junction/crack
+problem; it is safe because it is *conformal by construction*. Only **terminal** edges are ever bisected
+- an edge that is the longest edge of *every* triangle sharing it - which splits both those triangles
+along one shared midpoint at once, so a hanging node is never created. The edge to split for a triangle
+that wants refining is found by **longest-edge propagation (LEPP)**: walk to the longest edge of
+ever-longer-edged neighbours until a terminal one is reached, and bisect that. Edge length strictly
+increases along the path (ties broken by mesh-vertex key, which both sides of an edge compute
+identically), so the walk cannot cycle, and Rivara's result is that repeating it refines the original
+triangle in a bounded number of bisections. The transition triangles it pulls in just outside the
+painted patch are the graded band that makes the size change conformal.
+
+The win: a small decal on a big model no longer quadruples the *whole* model's triangle count.
+
+**Run to completion, worst-first, against a triangle budget.** The refinement loop is not a fixed number
+of sweeps: it holds every triangle that is over its criteria in a max-heap keyed by *how many times over*
+it is, pops the worst, walks its LEPP, bisects, and re-scores. Edge adjacency (`nb[e]`, the triangle
+across each edge) is built **once** and maintained incrementally through each bisection, so the cost
+scales with the refined region rather than with the whole model. `max_triangles` is the only bound;
+stopping on it leaves a perfectly valid, still-conformal mesh that spent its budget on the largest errors.
+
+This shape replaced a first version that ran a fixed 12 sweeps, each rebuilding a whole-mesh edge map and
+bisecting one terminal edge per active triangle. Two failure modes came out of that, and they are worth
+remembering because they look like separate bugs and are not: the sweeps were consumed grading the
+*coarse surroundings* (whose edges are the longest, so they win every terminal-edge contest), which both
+**stopped refinement of the painted patch far short** of the requested detail and left the band outside
+it looking wildly over-refined relative to the patch itself.
+
+**It carries the paint forward**, which is what makes it usable (uniform/remesh both drop paint). Because
+the refinement is *driven by* the paint, the remap is trivial: `subdivide_mesh_adaptive()` fills an
+`out_source[new_tri] = input_tri` map (children inherit their parent), and the gizmo rebuilds each
+layer's mask on the new mesh - a new triangle is painted iff its source was fully painted in that
+layer. `collect_paint_region()` derives both:
+- the union refine-region: **exactly** the original triangles the brush touched, read straight off
+  `TriangleSplittingData::triangles_to_split` (`serialize()` records an entry per original triangle that
+  is either split - i.e. partially painted, the patch boundary - or carries a non-default state). No
+  dilation. An earlier version marked every triangle sharing a *vertex* with the patch, which drags in a
+  whole fan of huge unpainted neighbours and then refines *those* down to the resolution floor, since the
+  height field the detail test samples is not restricted to the painted area. The conformal closure
+  already grades the size change outward on its own; it does not need help.
+- the per-layer fully-painted-triangle sets (a `get_facets_strict(ENFORCER)` sub-triangle with all three
+  *original* vertex indices == a whole, fully-painted original triangle; a partial stroke's sub-triangles
+  always carry a split vertex).
+
+The other four channels still ride the normal `restore_painting()` remap. Covered by a conformality unit
+test (`every_edge_used_twice` on a partially-refined cube - an exact crack detector for a closed mesh),
+plus tests that the target edge length is actually *reached* and that the budget caps the result without
+opening a crack.
+
+Both share the gizmo's Preview/Apply/Done flow; the **"Only painted area (adaptive)"** checkbox picks
+the mode, and the adaptive preview follows the paint live (`rebuild_preview()` refreshes the wireframe
+while the subdivide preview is open in adaptive mode). The panel shows the previewed triangle count.
+
+**Feature-adaptive (follow texture detail).** A sub-mode of adaptive (the **"Follow texture detail"**
+checkbox) that puts triangles where the *displaced surface actually bends*, not evenly. The insight:
+a flat region or a linear **ramp** needs no extra vertices (linear interpolation is exact for a ramp);
+what needs them is **curvature** - the *second* derivative, not the gradient. So the extra predicate is a
+**chord-error** test: sample the combined displacement at the triangle's three edge midpoints *and its
+centroid* (sampling the interior is what catches a bump sitting inside a triangle, the blind spot of an
+edge-only test) and take the largest departure from the flat triangle's barycentric interpolation. Refine
+while that exceeds `chord_tolerance_mm` ("Detail (mm)"). Zero chord error on a ramp ⇒ untouched; high on
+a bump/ridge/noise ⇒ refined until captured. Same conformal machinery, so still crack-free. The
+per-triangle error is cached and recomputed only for the children of a split.
+
+Four knobs bracket it, and all four matter:
+- **"Max edge (mm)"** (`target_edge_length_mm`) is a **baseline that applies in feature mode too**.
+  Without it the chord test aliases: a big triangle over a fine pattern can sample four points that all
+  land at similar heights, report no error, and stall before refinement ever starts. The baseline
+  guarantees a sampling density fine enough for the curvature test to see the texture at all.
+- **"Detail (mm)"** is the chord tolerance above.
+- **"Min edge (mm)"** is a hard floor under both, and is what guarantees termination across a sharp
+  texture *step*, where the error never falls however fine the mesh gets.
+- **"Added triangles (k)"** is the budget, passed as `max_triangles` (the model's own triangle count plus
+  the slider, so the control still means something on an already-dense model).
+
+The height field is `make_combined_displacement_sampler()` - it mirrors `build_texture_displacement()`'s
+per-layer setup (decode, patch centroid, cylinder axis, blend order, "lowest layer folds additively")
+but evaluated per point. Two deliberate simplifications, both erring toward *more* detail (safe -
+over-refinement is never a crack): every sampleable layer is sampled at every point (no per-point paint
+test), and edge-smoothing falloff is ignored. Note the first one is *why* the refine region must not be
+dilated - outside the paint the sampler still reports full relief. **LSCM layers are skipped** (no
+per-point UV); a purely LSCM stack yields a null sampler and the code falls back to the length baseline
+alone. Per-vertex heights are sampled lazily, so a small patch on a huge model never pays for the rest of
+it. Covered by unit tests: a Gaussian bump refines densely at its center and leaves flat corners coarse,
+a linear ramp produces *zero* extra triangles (the case a gradient criterion would over-refine), and a
+flat field still honours the max-edge baseline.
+
+### Fast bump preview (GPU-only, no CPU meshing)
+
+`resources/shaders/{110,140}/texture_displacement_bump.{vs,fs}`, registered as
+`"texture_displacement_bump"`. Perturbs the *shading* normal from the height texture's local
+gradient instead of moving geometry - active-layer-only, toggled via a "Fast preview (normal map)"
+checkbox. Vertex format is `GLModel::Geometry::EVertexLayout::P3N3T2`: `normal.x` carries the
+per-vertex paint weight (0/1) and `tex_coord` carries a precomputed texture UV, so it can use
+`GLModel` normally instead of needing a hand-rolled VBO/VAO manager. Weight buffer is
+rebuilt at the same cadence as the true-displacement preview (stroke-end/slider-release), using the
+**live** `TriangleSelector` state (not the flushed model facets), so it doesn't lag by a full model
+round-trip.
+
+The perturbed normal is the analytic one for a height field `H = ±depth_mm · h(uv)` displaced along
+`N` over any orthonormal surface tangent pair `T`/`B`:
+
+    N' = normalize(N − (dH/da)·T − (dH/db)·B),   a = dot(p,T), b = dot(p,B)
+
+The two slopes have to be genuine **mm-per-mm** derivatives for the preview's apparent depth to
+match the bake's - see bug #13.
+
+**Two projection paths (`use_vertex_uv` uniform):**
+- **Triplanar (`use_vertex_uv = 0`)** - `uv` and the `T`/`B` axes are both derived in-shader from
+  the dominant normal component, mirroring `project_planar()`/`apply_uv_transform()`, and the slope is
+  formed analytically. `T`/`B` are the projection's axis-aligned pair, exact only when the face is
+  axis-aligned; the shader drops the along-normal component to keep the gradient in the surface. Here
+  one `uv` unit is exactly `tiling_scale` mm, so the `1/tiling_scale` gradient factor is right.
+- **Precomputed UV (`use_vertex_uv = 1`, used for LSCM)** - `uv` comes per-vertex from the CPU
+  (`compute_lscm_uvs(patch, layer)`, so island placement + tiling/rotation/offset are already folded
+  in), and the perturbed normal is built with **Mikkelsen's method** ("Bump Mapping Unparametrized
+  Surfaces on the GPU"): the surface gradient taken directly from the screen-space derivatives of the
+  *sampled height* and position. **This makes no uv→mm scale assumption**, which is essential -
+  the first cut used the same global `1/tiling_scale` factor as triplanar and the depth came out
+  visibly wrong, because an LSCM map is **conformal, not isometric**: it is globally area-scaled but
+  the *local* mm-per-uv varies across the chart. `dFdx(h)` captures the true on-screen rate of change
+  however the chart is stretched. **This path is also what makes the fast preview follow the UV
+  editor: move an island and its uv - hence its bump - moves with it** (the bump mesh rebuilds on
+  drag-end, since `on_island_edited(finished)` → `rebuild_preview()` → `rebuild_bump_preview_mesh()`).
+  The branch is uniform (`use_vertex_uv` is a uniform) and the paint weight gates by multiply, so the
+  texture derivatives stay well defined. A triangle straddling a seam has a discontinuous uv → the
+  `det≈0` guard skips it (a localised preview-only artifact, never in the bake).
+
+Remaining deliberate approximation: the GPU sampler's wrap mode stands in for
+`tile_enabled`/`tile_method`, so with tiling *off* the GPU repeats where the CPU returns 0 outside
+`[0,1)`.
+
+### On-canvas "Adjust Texture" gizmo
+
+A per-active-layer toggle ("Adjust placement (drag on model)") that disables painting and shows a
+flat pan panel (free 2D drag on both axes) plus two arrows along the patch's own U/V axes
+(constrained single-axis drag). Anchored to the painted patch's centroid/average-normal
+(`compute_layer_paint_anchor()`). Hit-testing is screen-space distance/point-to-segment (not real
+3D ray intersection against the handle geometry) - simple and good enough at this handle size.
+
+### Projection frame overlay (ViewProjected)
+
+`src/slic3r/GUI/TextureProjectorFrame.hpp/.cpp` - a semi-transparent, resizable `wxFrame` the user
+drags **over the 3D view**, like a slide projector's gate. Whatever the model shows through it is what
+the texture is projected onto, and the window's border becomes the hard edge of the displacement.
+Press **Apply projection frame** and the gizmo reads the window's rectangle and commits it.
+
+The window is deliberately **dumb**: it owns no placement state and reports nothing continuously. Its
+position and size *are* the placement, read on demand at Apply - which is also when the expensive
+visible-facet raycast runs. So dragging it is free and nothing recomputes until asked.
+
+Plain 2D (`wxPaintDC`), not a `wxGLCanvas`: a second GL canvas would have to share the app's one real
+`wxGLContext`, the cause of bugs #10 and #14 below. It only ever draws a bitmap and a border.
+
+**The projective mapping (`apply_projection_frame()`)**. The frame defines a
+**screen-space** rectangle, but the bake samples from a **local-space** position, so the two have to be
+reconciled. `view_project_right/up` can only express an *affine* projection - exact under an
+orthographic camera, but wrong under perspective, where the near end of a part projects larger than the
+far end and no pair of axes reproduces that. So the layer instead stores a full projective map
+(`view_project_matrix`, row-major 3×4, `uv = (row0·p̃/row2·p̃, row1·p̃/row2·p̃)`), built like this:
+
+- `K = projection · view · (instance · volume)`, i.e. local → clip, the same product the renderer uses.
+  Note `Camera::get_projection_matrix()` is typed `Transform3d` (nominally affine) but its perspective
+  form explicitly writes a `(0, 0, −1, 0)` bottom row into the underlying 4×4, so `clip.w = −z_eye` is
+  genuinely carried. The build therefore multiplies **`.matrix()` products** (plain `Matrix4d`), never
+  `Transform3d` products, which would not compose that row correctly.
+- Window coordinates follow `igl::project`'s convention (as `CameraUtils::project` does), with y
+  measured downward. Writing `uv = (win − rect_origin) / rect_size` makes u and v affine in
+  `ndc = clip.xyz / clip.w`; multiplying through by `clip.w` leaves a plain linear combination of `K`'s
+  rows, which is exactly the 3×4 matrix - the perspective divide survives intact.
+- `w > 0` is checked rather than divided blindly. A point behind the projector has `w < 0` and divides
+  to a plausible-looking but **mirrored** uv - the classic way a projected decal reappears on the back
+  of a model. `project_uv_projective()` returns false there and the caller treats it as no height.
+
+The map already includes placement, so `apply_uv_transform()` is **not** applied on top of it - the
+window's own position and size are the placement, and the tiling/rotation/offset sliders would shove
+the result off the frame the user just aligned. A "Clear" button drops back to the affine path where
+those controls mean something again.
+
+Apply also sets `tile_enabled = false`, so `DecodedHeightTexture::sample()` returns 0 outside `[0,1)`
+and the border is a hard edge rather than the first seam of an endless repeat, and repaints the layer
+via `select_visible_faces(&matrix)` - the frame's uv square clips the selection, which both matches the
+paint to the border and keeps the ray queries proportional to the framed area instead of the model.
+
+Owned by the gizmo and **destroyed** (not just hidden) in `on_shutdown()`. Closing it only hides it, so
+reopening keeps it where it was left.
+
+### UV Editor pane
+
+`UVEditorCanvas` (`src/slic3r/GUI/UVEditorCanvas.hpp/.cpp`) - a standalone `wxGLCanvas` rendering the
+flattened LSCM islands (per-island wireframe + outline + fill) over the height texture (background
+quad tiled across the whole unwrap), with mouse pan/zoom. It is wrapped in a **`UVEditorPanel`**
+(same file) that adds a button row (Frame / Snap / Average scale) and a status line
+along the bottom naming the current gesture and the shortcuts in play. The *panel* is what is
+registered as a `wxAuiPaneInfo` pane on `Plater`'s `m_aui_mgr`; `Plater::show_uv_editor(bool)`
+shows/hides it (deferred via `CallAfter`, since the gizmo calls it mid-3D-frame), and
+`get_uv_editor_canvas()` returns the inner canvas the gizmo talks to.
+
+Deliberately **shares the app's one real `wxGLContext`** (`wxGetApp().init_glcontext(*this)`, the
+same call `View3D`/`Preview`/`AssembleView` make) rather than creating an independent context like
+`SkipPartCanvas` does elsewhere in this codebase - this is what lets it reuse the already-registered
+`"flat"`/`"flat_texture"` shaders and `GLModel` as-is, instead of needing its own shader
+compilation/VBO management.
+
+**Geometry is uploaded once, in the unwrap's own (raw, mm) coordinates**, one `GLModel` set per
+island; each island is then drawn through its own 2x3 affine (`island_transform_matrix()` composed
+with the layer's tiling/rotation/offset) passed as the `flat` shader's `view_model_matrix`. A 
+drag updates one matrix per island and touches no vertex
+buffer - `on_island_edited(!finished)` calls only `set_island_transforms()`, and the full
+`set_islands()` rebuild happens solely when the unwrap itself changes (`unwrap_changed` in
+`update_uv_editor()`).
+
+**Gestures** (canvas-owned, reported to the gizmo as incremental deltas via `IslandEditFn`): left-drag
+= move, right-drag or **R** = rotate (hold **Shift** to snap to 15° steps - quantised on the
+*cumulative* rotation, not each delta, so it doesn't judder, and accumulated incrementally so it
+survives crossing ±180°), **S** = scale (R/S modal, click/Enter to confirm, Esc to cancel), wheel =
+zoom about the cursor, middle-drag = pan, **Home**/**F** = frame all. Scale writes
+`TextureIsland::scale`; "Average scale" (`average_island_scales()`) sets every island to the mean, so
+one island scaled by hand can be matched back to its neighbours' texel density. **Snap** (canvas-owned
+`m_snap_enabled`, toggled from the toolbar) sticks a dragged island's nearest boundary vertex onto a
+neighbouring island's at drag-*end* only - a magnet that re-applies mid-drag is very hard to pull out
+of. Toolbar commands the canvas can't service itself (Average scale) are forwarded to the gizmo via
+`CommandFn`; view-only ones (Frame, Snap) it handles directly.
+
+## Known limitations / deferred work
+
+- **No `.3mf` serialization** for texture-displacement paint data or texture assets. A background
+  agent attempted this in an earlier session, hit its own usage limit mid-edit, and left
+  `bbs_3mf.cpp` with an undefined forward-declared function; that partial edit was reverted rather
+  than shipped broken. Practical impact: **baked** geometry round-trips fine (it's just an ordinary
+  part of the mesh via the existing mesh serialization path) - what does *not* survive a project
+  save/reload is any *unbaked* paint stroke and texture layer definition.
+- **No remap-across-topology-change** for texture-displacement paint (`ModelObject::split()`, mesh
+  boolean ops, Simplify, uniform subdivide, and remesh all drop it via `reset_extra_facets()`). The
+  other four paint channels (supported/seam/mmu/fuzzy) do get remapped in these cases. The lone
+  exception is **adaptive subdivide**, which carries texture-displacement paint forward itself via its
+  source map (see the Subdivision section) - a targeted remap that only works because the operation is
+  driven by the paint.
+- **Cylindrical/Spherical axis/center are auto-picked heuristically**, not user-controllable - no
+  UI to override the auto-detected wrap axis if it picks the "wrong" one for an odd shape.
+- **Fast preview covers the active layer only** — and is now the **default** view when the gizmo
+  opens (`m_use_bump_preview = true`): it is the instant, no-CPU-meshing preview, so it is the better
+  first impression while painting. The exact true-displacement view is one click away in the View row.
+- **Displacement resolution is capped by the mesh's own vertex density.** Baking only ever *moves*
+  existing vertices (it never inserts any), so a coarse patch cannot show fine texture detail no
+  matter how high-resolution the height map is - that is what the subdivision controls are for
+  (uniform, adaptive, or feature-adaptive; see the Subdivision section). Since the rewrite the bake is
+  topology-preserving, so this is now a hard, explicit property rather than something partly papered
+  over by the old per-layer re-meshing.
+
+## File map
+
+**libslic3r (core, no GUI dependency):**
+- `src/libslic3r/TextureDisplacement.hpp/.cpp` - data model, bake algorithm, projection methods,
+  tiling, subdivision (uniform + adaptive longest-edge bisection), post-process smoothing
+  (`smooth_mesh_vertices()`), and `TextureDisplacementOptions` (the whole-stack settings). See doc
+  comments throughout, they're kept accurate and up to date.
+- `src/libslic3r/MeshBoolean.hpp/.cpp` - added `parameterize_lscm()` and `remesh_isotropic()`
+  in the `cgal` sub-namespace,
+  reusing the existing `CGALMesh`/`_EpicMesh`/conversion-helper infrastructure already there for
+  mesh boolean ops. New CGAL includes: `Polygon_mesh_processing/border.h`,
+  `Polygon_mesh_processing/connected_components.h`, `Surface_mesh_parameterization/{Error_code,
+  LSCM_parameterizer_3, parameterize}.h`. No new dependency - CGAL 5.6.3 is already vendored and
+  the `Surface_mesh_parameterization` package headers were already present, just unused before now.
+- `src/libslic3r/Model.hpp/.cpp` - the 8 named `FacetsAnnotation` fields + accessor,
+  `texture_displacement_layers`, `texture_displacement_options`, and all the mirrored touch points
+  (see Data model above).
+
+**GUI:**
+- `src/slic3r/GUI/Gizmos/GLGizmoTextureDisplacement.hpp/.cpp` - the gizmo. Panel controls: dock/
+  undock toggle, brush/face/connected-area selection mode + "select whole model" button, per-layer
+  texture picker + depth/tiling/rotation/invert/tile-mode/projection-mode/blend-mode controls,
+  "Adjust placement" toggle (on-canvas gizmo), "Fast preview (normal map)" toggle, "Subdivide model"
+  button, Add layer/Erase all/Bake.
+- `src/slic3r/GUI/TextureLibrary.hpp/.cpp` - scans the shipped + user texture folders, imports an
+  arbitrary image into the user folder (converting it to the 8-bit grayscale PNG libslic3r decodes),
+  and loads a library file's bytes for a layer. The image→grayscale-PNG conversion lives here, on the
+  GUI side, because libslic3r has no image toolkit; both the import path and the "pick a shipped
+  texture" path go through the same one function.
+- `resources/textures/displacement/*.png` - the 10 shipped height maps (Bricks, Grid, Hexagons,
+  Knurl, Noise, Quilt, Studs, Waves, Weave, Wood Grain). All 512×512 8-bit grayscale and **seamless**
+  (each is periodic over the full image in both axes, so tiling shows no seam). Generated
+  procedurally; the whole `resources/` tree is installed recursively by CMake, so a new folder under
+  it ships with no build-system change.
+- `src/slic3r/GUI/Jobs/TextureDisplacementBakeJob.hpp/.cpp` - background bake commit.
+- `src/slic3r/GUI/Jobs/TextureDisplacementPreviewJob.hpp/.cpp` - background preview compute
+  (mirrors the bake job's shape but commits nothing to the Model).
+- `src/slic3r/GUI/TextureProjectorFrame.hpp/.cpp` - the semi-transparent projection-frame overlay for
+  ViewProjected layers (plain 2D `wxPaintDC`, no GL context - see its section above).
+- `src/slic3r/GUI/UVEditorCanvas.hpp/.cpp` - the 2D UV unwrap viewer widget.
+- `src/slic3r/GUI/Plater.hpp/.cpp` - `uv_editor_canvas` member, AUI pane registration,
+  `get_uv_editor_canvas()`/`show_uv_editor()`.
+- `src/slic3r/GUI/GLShadersManager.cpp` - registers `"texture_displacement_bump"`.
+- `resources/shaders/{110,140}/texture_displacement_bump.{vs,fs}` - the bump-preview shader.
+- `src/slic3r/GUI/Gizmos/GLGizmoPainterBase.hpp` - `PainterGizmoType::TEXTURE_DISPLACEMENT`.
+- `src/slic3r/GUI/Gizmos/GLGizmosManager.hpp/.cpp` - `EType::TextureDisplacement` registration.
+- `src/slic3r/GUI/ImGuiWrapper.cpp` - the light-mode checkmark-color fix
+
+**Tests:** `tests/libslic3r/test_texture_displacement.cpp` - **run and passing** (7 cases, 116
+assertions). Covers `decode_height_texture` round-trip, empty-layer no-op, full-cube uniform
+displacement, boundary-vertex pinning on a hand-built fan mesh, and - added with the bake rewrite -
+a regression test that a **second layer over the same area actually contributes**,

+# Texture Displacement — Feature & Controls Guide
+
+Texture Displacement is a paint-style gizmo that stamps height-map textures onto a model's surface
+and turns them into real relief — engraved or embossed detail — either as a live preview or baked
+into actual mesh geometry. You paint where the texture applies, stack multiple textures as blended
+layers, choose how each is projected onto the surface, and (for the unwrap projection) lay the result
+out by hand in a dedicated 2D **UV Editor** pane.
+
+This document describes every feature and control. For the internal architecture and algorithms, see
+`TEXTURE_DISPLACEMENT.md`.

+
+## Quick start
+
+1. Select an object and open the **Texture displacement** gizmo from the left toolbar.
+2. A texture layer is added automatically. Pick a texture from the layer's picker, or import your own.
+3. **Paint** the area you want the texture to affect (or press **Select whole model**).
+4. The relief appears live on the model. Tune **Depth**, **Tile size**, **Rotation**, etc.
+5. If the model is low-poly, use **Subdivide** or **Remesh** so there are enough vertices for detail.
+6. Press **Bake** to convert the preview into real geometry, or leave it as a live preview.
+
+> The tool only ever affects the **painted** area. Everything you don't paint keeps its original
+> surface, and bake blends the relief seamlessly into it.
+
+---
+
+## Entering the tool
+
+The gizmo lives on the left gizmo toolbar (icon: `toolbar_texture_displacement.svg`). Its settings
+panel opens beside the toolbar. You can **Dock panel / Undock panel** (top of the panel) to pin it or
+float it freely over the 3D view, and **Close** at the bottom exits the gizmo.
+
+When you first open the tool on a never-textured object it starts with **one texture layer already
+added**, so you can paint straight away.
+
+---
+
+## Selection modes
+
+Choose *how* you paint. All three write into the **active layer's** mask.
+
+| Mode | What it does |
+|------|--------------|
+| **Brush** | Free-hand painting with a round brush. Shows a **Brush size** slider and a **Circle / Sphere** choice (circle = surface disc, sphere = 3D ball that also paints around curves). |
+| **Face** | Click a single triangle to paint it. |
+| **Connected area** | Click to flood-fill a region; the **Angle threshold** slider limits how far the fill spreads across changes in surface angle. |
+
+- **Select whole model** — marks the entire model as painted for the active layer, instead of
+  brushing it by hand.
+
+---
+
+## View modes
+
+A row of icon buttons labelled **View** controls how the painted area is shown. The first four are a
+radio group; **Wireframe** is an independent toggle. Hover any icon for its tooltip.
+
+| View | Meaning |
+|------|---------|
+| **Normal** | The true displaced geometry — exactly what **Bake** produces. Rebuilt in the background. |
+| **Fast** | A GPU bump-shaded approximation of the *active layer only*. No real geometry movement — quick to update, not exact. Best while tuning or dragging islands. |
+| **Checker** | A test grid painted over the unwrap so you can see stretching (squares stay square where the map isn't distorted). |
+| **Distortion** | A blue→green→red heatmap of how much each area is compressed or stretched in UV space. Needs the **Unwrap (LSCM)** projection. |
+| **Wireframe** | Overlays the mesh edges (white). Independent of the view above; in **Normal** view it sits on the displaced surface. |
+
+---
+
+## Auto update
+
+**Auto update** (on by default) rebuilds the true displaced geometry as soon as *anything* changes —
+painting, swapping textures, moving sliders. Turn it off on very heavy models to only rebuild when you
+release a slider (painting still updates on stroke end).
+
+---
+
+## Texture layers
+
+You can stack up to **8** texture layers. Each has its own independent paint mask, its own texture,
+and its own parameters, and they combine in slot order like layers in an image editor.
+
+- **Add a layer** — the **＋ icon** to the right of the *Texture layers* heading (reuses the tool icon
+  for now).
+- **Remove** — the button on each layer's header row.
+- **Active layer** — click a layer's header (or anywhere in its block) to make it active. The active
+  layer is the one you paint into and the one whose block is tinted. Only one layer is active at a time.
+- **Erase all** — clears the active layer's paint.
+
+Each layer shows a texture **picker** (large preview + name). Open it to choose from the shipped
+library or import your own image (any png/jpg/bmp; it's converted to an 8-bit grayscale height map and
+copied into your user texture folder so app updates can't overwrite it).
+
+---
+
+## Per-layer settings
+
+| Control | Range / options | What it does |
+|---------|-----------------|--------------|
+| **Depth (mm)** | 0.01–10 (log) | Maximum displacement along the surface normal. |
+| **Tile size (mm)** | 0.2–200 (log) | Physical size of one texture tile on the surface. |
+| **Rotation** | 0–360° | Rotates the texture on the surface. |
+| **Midlevel** | 0–10 | The grey level that means "don't move". At 0 the texture only pushes outward; raise it and darker texels cut *inward* (one map both embosses and engraves). 0.5 makes mid-grey neutral. |
+| **Smoothing** | 0–1 | Blurs the height texture before it displaces — rounds hard edges and removes speckle without needing a softer source image. |
+| **Edge smoothing** | checkbox + **Edge amount** 0–1 | Fades the relief to flat toward the *edge of the painted area*, so it blends into the surrounding surface. A small amount softens only a thin band at the very edge; the maximum flattens the whole painted face. |
+| **Invert** | checkbox | Flips the height map (peaks become valleys). |
+| **Blend** | Add / Subtract / Multiply / Divide | How this layer combines with the layers **below** it where they overlap. Add/Subtract pile relief on or carve it away; Multiply/Divide scale the relief underneath (a mask). The lowest painted layer is the **Base** and always behaves additively. |
+| **Tile** | checkbox + **Repeat / Mirrored repeat** | When off, the texture is placed once (a decal) instead of repeating. Mirrored repeat flips every other tile to hide seams. |
+| **Projection** | see below | How the texture is mapped onto the painted surface. |
+
+> **Midlevel warning:** cutting inward can fold the surface through itself in sharp concave corners or
+> thin walls. Keep Depth small relative to the feature you're cutting into; the panel warns when a deep
+> inward setting is risky.
+
+---
+
+## Projection methods
+
+How the 2D texture is wrapped onto the 3D painted area.
+
+| Method | Best for | Notes |
+|--------|----------|-------|
+| **Triplanar (blended)** | Patches wrapping around edges | Projects from all three axes at once and blends, so there's no seam across a sharp edge. |
+| **Cylindrical** | Round, tube-like selections | Wraps the texture around the patch's own centre/axis. |
+| **Spherical** | Ball-like selections | Longitude/latitude wrap around the patch centre. |
+| **Unwrap (LSCM)** | Flat, controlled layout | A real conformal unwrap. Cuts the area into pieces at sharp edges (see **Seam angle**), flattens each, and lets you lay them out by hand in the **UV Editor**. Unlocks Checker/Distortion, seams, and island editing. |
+| **From view** | Decals / slide-projector look | Projects straight onto the surface from the current camera direction. Use **Capture current view** to re-lay it from wherever you're looking. |
+
+### LSCM-only controls
+
+These appear when a layer uses **Unwrap (LSCM)**:
+
+- **Seam angle** (5–90°) — edges sharper than this are cut so each piece lies flat. Lower cuts more
+  (less stretching, more seams); raise to keep more in one piece. A box's 90° corners are cut by
+  default. *Ignored once you've marked any seam by hand* (your seams then define the pieces).
+- **Connect islands** (on by default) — lays the unwrap out as a **connected net**: pieces that share
+  an edge are unfolded next to each other (a cube becomes a joined net instead of six loose squares).
+  They stay separate islands, so you can still move any of them by hand. Turn off for the classic
+  packed-grid layout.
+- **Open UV editor** — shows the flattened unwrap in a side pane (see below). Opens *only* when you
+  turn this on — it never pops up on its own.
+- **Mark seams** / **Path** / **Clear seams** — see [Seams](#seams).
+- An **Unwrap: N islands, F faces, V verts** read-out tells you what the unwrap actually produced.
+
+---
+
+## The UV Editor
+
+A dockable 2D pane (enable **Open UV editor** on an LSCM layer) showing the flattened unwrap over the
+height texture. Islands are the flattened pieces; you can rearrange them freely — nothing re-packs them
+behind your back. Moving an island updates the model **live** (in Fast view it tracks the cursor
+smoothly, via a shader uniform — no rebuild until you release).
+
+### Navigation
+
+| Action | Control |
+|--------|---------|
+| Pan | Middle-drag |
+| Zoom | Mouse wheel (zooms about the cursor) |
+| Frame everything | **Home** or **F**, or the **Frame** toolbar button |
+
+### Editing an island
+
+| Action | Control |
+|--------|---------|
+| Select | Left-click an island |
+| Move | Left-drag |
+| Rotate | Right-drag, or press **R** then move the mouse (click/Enter to confirm, Esc to cancel) |
+| Rotate snapped | Hold **Shift** while rotating — snaps to **global** 15° marks (0/15/30…). A protractor dial with tick marks and the current angle is shown. |
+| Scale | Press **S** then move the mouse (click/Enter to confirm, Esc to cancel) |
+| Undo / Redo | **Ctrl+Z** / **Ctrl+Shift+Z** or **Ctrl+Y** |
+
+The **selected** island gets a bold light-green outline and a brighter wireframe; unselected islands
+are a translucent light-green wash. The texture underneath repeats exactly as it will when baked.
+A **status line** along the bottom always names the current gesture and the shortcuts in play.
+
+### Toolbar
+
+| Button | Action |
+|--------|--------|
+| **Frame** | Frame all islands (same as Home). |
+| **Snap** | Toggle magnetic snapping — a dragged island sticks its boundary to a neighbour's when they come close. |
+| **Avg scale** | Give every island the same texel density (Blender's "Average Islands Scale"). |
+| **Cut** | Split the selected island across its long axis (useful for very long islands). |
+| **Join** | Unfold the selected island onto its nearest neighbour along their shared edge — keeps both as separate islands with their own borders. |
+| **Unjoin** | Send the selected island back to its own packed position. |
+
+> **Checker / Distortion in the UV editor:** selecting those View modes also colours the UV pane — a
+> checker background, or a per-island distortion heatmap — so you can judge stretch in 2D as well as
+> on the model.
+
+---
+
+## Seams
+
+Seams are edges the unwrap is forced to cut along, on top of whatever the Seam angle cuts — the
+Blender "mark seam" workflow. They let you control exactly where the unwrap splits.
+
+Enable **Mark seams** on an active LSCM layer, then:
+
+- **Click an edge** on the model to mark it (it turns **red**); click a red edge again to unmark it.
+  The edge under the cursor is highlighted **yellow** so you can see what a click will toggle.
+- **Path mode** (the **Path** checkbox) — for dense meshes where clicking each edge is tedious: click a
+  start point, then an end point, and the whole **shortest path** between them is seamed at once. It
+  chains (each click extends from the last point); the start vertex is shown in **green**.
+- **Ctrl+drag** rotates/pans the camera while in seam mode.
+- **Clear seams** removes them all.
+
+Once any seam is marked, the automatic Seam-angle cutting is disabled so *your* seams define the
+islands — pieces you leave un-seamed merge together.
+
+---
+
+## Adjust placement (on-model)
+
+**Adjust placement** (on an active layer) lets you position the texture by dragging a handle on the
+model instead of nudging the Rotation/offset numbers. The handle is a flat panel in the patch's
+tangent plane (drag anywhere on it to move freely) plus U/V arrows for single-axis nudges. It's
+anchored to the painted patch, so paint something first.
+
+---
+
+## Preparing the mesh: Subdivide & Remesh
+
+Displacement can only move vertices that exist, so a coarse model needs more of them first.
+
+### Subdivide
+
+Splits every triangle into four, **1–5 times** (each step roughly quadruples the triangle count).
+
+- **Subdivide steps** (1–5) — how many times to split.
+- **Preview subdivision** — shows the result as a **cyan wireframe** without changing the model.
+- **Apply** — commits the subdivision to the geometry.
+- **Done** — ends the preview and leaves the model as it is.
+
+### Remesh
+
+Rebuilds the whole model with triangles close to a target edge length — evens out a mesh with wildly
+varying triangle sizes (CGAL isotropic remeshing).
+
+- **Target edge (mm)** — desired triangle edge length (seeded to the model's current average).
+- **Remesh** — splits the big triangles and merges the small ones to that size.
+
+> Both Subdivide-Apply and Remesh **replace the geometry** and clear any *not-yet-baked* paint on it
+> (already-baked relief is kept). If you had the mesh **Wireframe** on before, it stays on afterward.
+
+---
+
+## Baking & resetting
+
+- **Bake** — converts the current preview into real, permanent mesh geometry, restricted to the
+  painted area. Runs in the background; the button shows *Baking…* while it works.
+- **Erase all** — clears the active layer's paint.
+
+Baking is the exact same algorithm as the **Normal** preview, so what you see is what you get.
+
+---
+
+## Controls reference
+
+### Mouse — 3D view (while painting)
+
+| Input | Action |
+|-------|--------|
+| Left-drag | Paint the active layer |
+| Ctrl + drag | Rotate / pan the camera (works in seam mode too) |
+| Wheel | Zoom |
+
+### Mouse & keys — UV Editor
+
+| Input | Action |
+|-------|--------|
+| Left-click | Select island |
+| Left-drag | Move island |
+| Right-drag | Rotate island |
+| **R** / **S** | Modal rotate / scale (mouse drives it, click or Enter confirms, Esc cancels) |
+| **Shift** (while rotating) | Snap to global 15° marks |
+| Middle-drag | Pan |
+| Wheel | Zoom about cursor |
+| **Home** / **F** | Frame all islands |
+| **Ctrl+Z** / **Ctrl+Shift+Z** / **Ctrl+Y** | Undo / redo |
+
+### Seam mode
+
+| Input | Action |
+|-------|--------|
+| Click edge | Mark / unmark a seam (yellow = hover, red = marked) |
+| Click (Path mode) | Set start, then seam the shortest path to the next click |
+| Ctrl + drag | Rotate / pan camera |
+
+---
+
+## Tips & limitations
+
+- **Paint first, then bake.** The preview is free to explore; only Bake changes the real mesh.
+- **Not enough detail?** Subdivide or Remesh before painting fine textures.
+- **Inward cuts** (high Midlevel + big Depth) can self-intersect on thin walls or sharp concave
+  corners — keep Depth modest there.
+- **Fast vs Normal:** Fast preview shades a bump and shows only the active layer; use it for quick
+  tuning and smooth UV dragging, but trust **Normal**/**Bake** for the exact result.
+- **Topology changes drop unbaked paint.** Subdivide-Apply, Remesh, and Simplify replace the mesh, and
+  texture-displacement paint isn't remapped across that change (already-baked relief is unaffected).
+- **Island placements** are tied to the current unwrap. Re-painting or changing the Seam angle can
+  re-segment the charts and renumber them, so a re-unwrap re-lays the connected net and discards
+  hand placements made before it.
+- **Connect islands** is on by default; turn it off (per layer) for the classic packed-grid layout, or
+  if an unfold looks wrong on an unusual mesh.

-# Printer agents
-
-Printer agents let OrcaSlicer communicate with printers through a
-standardized protocol. They translate between a printer's
-native API and the application interfaces that the app already
-uses.
-
-This documentation explains the compatibility boundary, runtime ownership,
-connection and status flow, command and feature behavior, built-in and plugin
-agent implementations, and the testing evidence required for compatibility
-claims.
-
-## What printer agents do
-
-A printer agent has two jobs:
-
-1. Accept the app's existing commands and translate the ones its
-   printer supports.
-2. Convert native printer status into correctly-shaped state that
-   `MachineObject` understands.
-
-Currently, agents work at a compatibility boundary, i.e., making other vendors compatible with Bambu-shaped code, not a vendor-neutral one.
-Some Bambu concepts remain part of the payload and command vocabulary.
-End goal is to make the whole command and payload interfaces vendor-neutral.
-
-## Vocabulary
-
-Every chapter reuses these terms. The "Is not" column is the part that
-causes confusion when it is left implicit.
-
-| Term | Is | Selected by | Is not |
-| --- | --- | --- | --- |
-| Agent ID | Which printer agent implementation to use | `printer_agent` on the printer preset; empty is the legacy `bbl`-or-`orca` sentinel | Which printer |
-| Printer agent | The live `IPrinterAgent` instance for that ID, created and cached once per ID by `NetworkAgentFactory` | Factory lookup on the agent ID | A connection, and not one object per printer |
-| Device ID | One printer inside that implementation | Bind with Access Code for the Moonraker family, where the entered address becomes the ID; Bambu uses its own discovery identity | Which protocol |
-| `MachineObject` | The Device tab's view of one selected printer | `DeviceManager::selected_machine`, which stores only an ID | Proof that a printer is reachable |
-| Freshness | `is_connected()`, a test over the last-update time | Any reset of the update time, including one no status has followed | Proof that status arrived |
-| Status-confirmed readiness | A push-status message has actually been parsed | The first real status message | The same thing as a successful `connect_printer()` |
-
-Earlier drafts used "transport" for the printer agent instance. That term
-is retired: the code selects an implementation, not a wire protocol.
-
-## How to use this guide
-
-- [Architecture](architecture.md) describes objects, ownership, lifetimes,
-  error handling, the feature gate, and compatibility contracts for printer
-  agents.
-- [Connection and status](connection-and-status.md) describes how presets,
-  machines, access codes, status messages, and commands fit together at
-  runtime. Unlike Architecture, it follows the sequence of selecting an
-  agent, connecting, receiving status, and sending commands.
-- [Printing](printing.md), [filament synchronization](filament.md), and
-  [camera support](camera.md) are separate chapters because they contain
-  per-feature detail rather than because they are universally special:
-  Printing has its send, preflight, recovery, and start contracts; Filament
-  covers acquisition, mapping selection, and print-time delivery; Camera
-  covers the distinct Bambu, Moonraker, and Snapmaker ownership models.
-- [Built-in agents](agents.md) describes the Moonraker family and the Qidi,
-  Snapmaker variants.
-- [Python plugin agents](plugin-agents.md) describes the plugin bridge and
-  lifecycle.
-- [Testing and troubleshooting](testing.md) explains automated checks, manual
-  hardware work, known defects, and the evidence required for compatibility
-  claims.
-- The [capability matrix](reference/capability-matrix.md) is the compact
-  feature reference. The [manual checklist](reference/manual-checklist.html)
-  is for a live-printer verification pass.
-
-Treat source code as authoritative when it differs from this guide. In
-particular, preserve the compatibility rules called out in each chapter:
-they protect stored presets, existing profiles, and the Device tab's
-assumptions.

-# Built-in printer agents
-
-*Owns the per-vendor behavior of the built-in agents: what each subclass
-changes and what it inherits unchanged. Defers the interface every agent
-implements to [Architecture](architecture.md) and
-[Python plugin agents](plugin-agents.md).*
-
-This chapter covers the built-in Moonraker family: the general
-`MoonrakerPrinterAgent` and the Qidi and Snapmaker variants. Creality
-(`CrealityPrintAgent`) is also a member of this family and inherits the base
-behavior, but has no section here; see the capability matrix for its
-per-feature coverage. They share the same connection and status machinery.
-Change the base class only when the behavior is valid for all of them.
-
-Each subclass is thin. `MoonrakerPrinterAgent` holds the HTTP connection,
-the WebSocket status subscription, the REST command worker, thumbnail
-lookup, the chamber-light heuristic, and the upload-and-start path.
-`QidiPrinterAgent` overrides filament discovery and adds multi-color box
-mapping; `SnapmakerPrinterAgent` overrides filament discovery and camera
-setup; `CrealityPrintAgent` overrides filament refresh. Each derives from
-`MoonrakerPrinterAgent` and is `final`, which is why the guard rule below
-must be type-based.
-
-## Moonraker family
-
-### Connection and commands
-
-Moonraker-family agents use plain HTTP for the LAN connection. The connection
-path deliberately ignores a TLS request because the supported printer stacks
-serve Moonraker or a reverse proxy over HTTP. Restoring the caller's TLS
-default can send a connection to an unavailable HTTPS endpoint.
-
-Status is a Moonraker WebSocket subscription. Commands use REST. Command
-translation happens immediately, but the resulting HTTP work runs through one
-agent-owned FIFO worker. Each queued operation captures the current base URL
-and API key before it is queued, so a later printer switch does not redirect
-an earlier command. Keep this separation: network work on the UI path makes
-controls feel stalled, and allowing a queued command to reread connection
-state can send it to the wrong printer.
-
-Pause, resume, and cancel use the dedicated Moonraker print endpoints. Do not
-replace them with queued `PAUSE`, `RESUME`, or `CANCEL_PRINT` G-code. The
-endpoints interrupt the print directly; a G-code command can wait behind the
-active print or macro.
-
-The request router accepts the Bambu-shaped JSON used by the native device
-tab. Supply object-shaped namespaces such as `print` and `system`. A malformed
-but parseable payload with a scalar where the router expects an object can
-still fail before the unsupported-command fallback. The supported generic fan
-status is the standard `fan` object, which represents the part fan only.
-Ordinary part-fan control also works through the legacy `gcode_line` path,
-which sends `M106` while `is_enable_np` is false. Auxiliary and chamber fans
-are neither reported nor controlled.
-
-Do not add `cfg`, `fun`, `aux`, and `stat` to the Moonraker status payload just
-to make it look more complete. Together those fields set `is_enable_np` and
-make the UI choose its structured fan and extruder commands instead. The
-Moonraker agent does not translate those commands, so working controls become
-unsupported no-ops. This is a UI-routing constraint, not a reason to expose
-structured fan support.
-
-### Status shown by the native device tab
-
-The agent translates Moonraker status into the Bambu-shaped status payload the
-existing Device tab understands. Some fields are necessarily synthetic:
-
-- The virtual SD-card readiness bit and a basic software-version row make the
-  native UI consider the printer ready. Each pull payload also ensures
-  `m_push_count` and `m_full_msg_count` are at least one and refreshes
-  `last_push_time`. Together with the normal-storage state and a placeholder
-  module version, this satisfies the native `is_info_ready()` and printing
-  gates. These are compatibility scaffolding, not reports of physical storage
-  or OTA support.
-- Current and total layers are emitted only when `print_stats.info` contains
-  numeric values. Moonraker may send `null`, and many profiles do not emit the
-  `SET_PRINT_STATS_INFO` data needed to populate them. Do not turn that gap
-  into a JSON conversion exception.
-- Remaining time is estimated from elapsed print time and virtual-SD progress.
-  It is omitted below two percent progress because the early estimate is too
-  unstable. Do not derive an ETA by subtracting Moonraker duration counters:
-  both are elapsed counters, so their difference is overhead, not remaining
-  time.
-- Temperature readings are available, but nozzle diameter and nozzle type are
-  not supplied in the status payload. The UI can therefore show an unknown
-  nozzle. Do not make print submission depend on those missing fields.
-
-### Camera thumbnails and lights
-
-For a running job, the agent asks Moonraker for thumbnails and chooses the
-widest usable entry, rather than assuming the first entry is useful. It accepts
-both thumbnail path spellings used by Moonraker versions, encodes each path
-segment, and caches the result by filename. A failed transient lookup is tried
-again only a bounded number of times; a clean response without a thumbnail is
-cached as a negative result. The response shape handling is source-derived,
-not hardware-verified.
-
-> **Do not perform this HTTP lookup while holding `payload_mutex`.** The
-> WebSocket thread builds the status payload under that mutex and the UI
-> path also needs it, so a thumbnail timeout taken under the lock would
-> stall status delivery or the UI. The lookup still blocks the WebSocket
-> thread briefly, so move it to a worker if that becomes measurable.
-
-Chamber-light control searches Moonraker objects for names that look like a
-light or a standalone LED, then writes the first matching pin, LED, or macro.
-The filter exists to avoid treating unrelated objects, such as a beeper, as a
-lamp. It remains a heuristic. The incoming `led_node` is validated, but only
-`chamber_light` is acted on; `chamber_light2` is deliberately ignored. A
-printer with more than one lamp therefore has no reliable node-to-object map.
-
-### Common maintenance limits
-
-The same cache is reused for a selected agent ID, not per physical printer.
-Qidi and Snapmaker inherit this behavior. A stateful feature added
-to the base class must be reset carefully when a preset switches hosts.
-
-> **Keep guards for this family type-based** - check whether an agent
-> derives from `MoonrakerPrinterAgent` rather than comparing its ID to
-> `moonraker`. An ID-based guard silently excludes Qidi, Snapmaker, and
-> Creality, even though they share the base behavior.
-
-The family has no generic implementation for firmware-specific AMS write
-commands. Keep unsupported commands unsupported until the printer-side macro
-or API is known. Reporting success for an untranslated command makes the
-native UI claim that an action happened when it did not.
-
-## Qidi
-
-Qidi inherits the Moonraker connection, status, camera, and local-print path.
-Its differences are Qidi filament discovery and the pre-print multi-color-box
-mapping.
-
-### Filament discovery
-
-Discovery first reads the printer's device information to infer a Qidi series
-identifier, then falls back to the configured Orca model if needed. Series
-inference intentionally recognizes only a narrow set of known names. An
-unknown model still produces usable generic filament data, but not a
-series-specific preset identifier.
-
-The agent reads a Qidi filament dictionary and the `save_variables` plus
-slot-runout data. Failing to fetch the dictionary is non-fatal: slot discovery
-continues with fallback material and colour values. Failing to fetch or parse
-slot data is fatal to the refresh. A missing runout value means the agent
-cannot prove filament is loaded, so it reports that slot as empty. This is an
-ambiguity in the firmware data, not proof that the box is empty.
-
-`save_variables.variables` must be an object. Qidi firmware can return `null`
-there, and generic JSON value access can throw on a present null. The parser
-rejects that shape without throwing. Preserve the null-slot tests whenever the
-response parser changes.
-
-### Multi-color mapping before a print
-
-Before every Qidi print-start wrapper, the agent writes `enable_box` and, for
-mapped tools, persistent `value_t<tool>` variables. These writes survive the
-job. Invalid mapping JSON is checked only after `enable_box` has been written.
-When the mapping is enabled, that failure can therefore leave `enable_box=1`.
-There is no rollback for this or for a later per-tool write failure, so a
-partial mapping can remain on the printer. An empty mapping is accepted when
-the box is enabled. Single-colour jobs disable the box but leave old per-tool
-assignments in place.
-
-`enable_box` currently follows `task_use_ams`. That meaning has not been
-verified against all Qidi firmware: if firmware treats it as "a box exists"
-rather than "use the box for this job", this gate is wrong and needs hardware
-evidence before it changes.
-
-Only `start_local_print` reaches Moonraker's real upload-and-start path. The
-other Qidi mapping wrappers currently return success stubs after applying the
-mapping. Do not describe those wrappers as confirmed print paths.
-
-Because the agent cache is keyed by agent type, a Qidi mapping can also become
-stale when switching between Qidi printers. This is a generic Moonraker-family
-state risk, made more consequential by Qidi's persistent firmware variables.
-The configured `printer_type` can also be stale, so treat it as a fallback
-hint rather than device truth.
-
-## Snapmaker
-
-Snapmaker uses the Moonraker base and overrides filament discovery and camera
-setup. Neither path is hardware-verified in the current documentation set.
-
-Filament information comes from parallel arrays in `print_task_config`.
-`filament_exist` defines the number of slots; shorter type, subtype, colour,
-vendor, or NFC arrays use safe fallback values. The agent first tries a visible
-vendor, type, and colour preset, then a visible type match, and finally a
-generic identifier when no preset bundle is available. An empty reported type
-is changed to `PLA`, so an unknown occupied spool can look like confirmed PLA.
-An unrecognized type can also reach the visible-preset fallback and be paired
-with an unrelated visible preset. Treat the resulting preset as a suggestion,
-not printer-ground truth.
-
-Snapmaker U1 camera support starts the printer's monitor RPC, then serves the
-still JPEG through a small local HTML page that reloads it after each load or
-error. The wrapper is required because a direct still-image URL looks frozen.
-The RPC is sent from a detached thread so the UI timer does not block on socket
-I/O. That thread captures `this` directly, so agent destruction can race with
-the camera command. Do not widen this pattern. Route future asynchronous work
-through owned lifetime-managed work where possible.

-# Architecture
-
-*Owns the structural rules: what the objects are, who owns them, what an
-agent must implement, and which behaviors are compatibility contracts.
-Defers the runtime sequence - selecting, connecting, receiving status,
-sending commands - to [Connection and status](connection-and-status.md).*
-
-## The compatibility boundary
-
-The Device tab was built around Bambu-style commands and status. A printer
-agent is the translation boundary between that existing contract and a
-vendor's native protocol:
-
-```text
-Device tab <-> MachineObject <-> NetworkAgent <-> IPrinterAgent
-                                            <-> vendor protocol
-```
-
-Note: end goal is to move beyond this and achieve a truly vendor-neutral translation layer.
-
-The GUI builds commands and reads `MachineObject` state. An agent owns the
-vendor request, response, connection, and status translation. Keep vendor
-details on the agent side of this boundary.
-
-Status translation is deliberately Bambu-shaped. Agents deliver payloads
-through the callbacks used by the existing Bambu path, and
-`MachineObject::parse_json()` interprets them. This preserves the Device
-tab's established behavior, but it is not a vendor-neutral protocol.
-
-Important (again): end goal is to move beyond this and achieve a truly vendor-neutral translation layer.
-
-## Runtime objects and ownership
-
-`NetworkAgent` is the facade used by the application. It holds one live
-`IPrinterAgent` pointer, which is initially null and may return to null
-when a selected ID is unavailable. Callers must handle the null case. An
-absent agent is an inert state, not permission to fall back to another
-printer agent. A fallback would connect to a different implementation than
-the one selected by the preset, and could therefore send commands or status
-work to the wrong printer.
-
-`NetworkAgentFactory` registers built-in and plugin implementations by
-agent ID. It creates and caches one implementation for each ID. The ID
-selects a printer agent implementation, while a `MachineObject` selects one
-printer by device ID. The resulting cardinality is one active agent to many
-machines.
-
-For example, suppose two Moonraker printers are on the LAN at
-`192.168.1.20` and `192.168.1.21`. In the Device tab machine-select popup, the
-user chooses **Bind with Access Code**; `PinCodePanel::on_mouse_left_up` opens
-`InputIpAddressDialog`, and each entered address is bound as a separate
-printer. Both presets store the same agent ID, `moonraker`, so
-`NetworkAgentFactory::create_printer_agent_by_id` returns the same cached
-`IPrinterAgent` pointer for both presets. Each printer nevertheless has its
-own `MachineObject` and device ID. For the Moonraker family,
-`MoonrakerPrinterAgent::bind_detect` calls `init_device_info` with the entered
-address as both the device ID and address, so the two device IDs are the two
-addresses.
-
-That is what one active agent to many machines means. Per-printer state must
-be keyed by device ID rather than held only on the agent instance, because one
-agent object is shared by both printers. State stored only on that object
-would be shared between two different machines and could route status or
-commands to the wrong one. The same sharing explains why
-`GUI_App::switch_printer_agent` compares device IDs even when the agent pointer
-is unchanged: otherwise its unchanged-agent early return would skip
-reselection when the user switches between these presets, leaving status and
-filament work aimed at the previous printer.
-
-> **Do not make an agent instance per printer just to hold device state.**
-> Keep per-printer state keyed by device ID, because one agent object is
-> shared by every printer of that type - state held on the instance would
-> route status or commands to the wrong `MachineObject`.
-
-> **Do not fall back to another printer agent when the live one is null.**
-> An absent agent is an inert state. A fallback would connect to a
-> different implementation than the preset selected.
-
-## Commands and unsupported work
-
-An agent must either translate a Device-tab command or return an explicit
-error. `ORCA_NETWORK_ERR_CMD_NOT_SUPPORTED` means no translation exists.
-`ORCA_NETWORK_ERR_CAP_NOT_AVAILABLE` means a translation exists but this
-printer cannot use it. `MachineObject::publish_json()` turns either result
-into the user-visible unsupported-command response.
-
-Every Device-tab command must leave by one of these four exits. The fifth
-path is the one to watch for in review:
-
-```mermaid
-flowchart TD
-    CMD["Device-tab command JSON"] --> PUSH{"pushing namespace?"}
-    PUSH -- yes --> OK1["Accept - the status stream already satisfies it"]
-    PUSH -- no --> TRANS{"Translation exists for this agent?"}
-    TRANS -- no --> E1["Return ORCA_NETWORK_ERR_CMD_NOT_SUPPORTED"]
-    TRANS -- yes --> CAP{"This printer can use it?"}
-    CAP -- no --> E2["Return ORCA_NETWORK_ERR_CAP_NOT_AVAILABLE"]
-    CAP -- yes --> OK2["Translate and send to the printer"]
-    TRANS -. FORBIDDEN .-> BAD["Return success without translating"]
-    E1 --> PUB["MachineObject::publish_json turns both errors<br/>into the unsupported-command response"]
-    E2 --> PUB
-    BAD --> LIE["UI reports an action that never happened"]
-```
-
-> **Do not return success for an unhandled command.** That makes an
-> unsupported button look as though it worked and hides missing coverage
-> from both users and maintainers.
-
-The `pushing` command namespace is the exception. Its request means
-"send status"; an active status stream already satisfies it. The Device
-Manager sends these requests repeatedly as a keepalive, so rejecting them
-would surface a warning repeatedly even though no action is missing.
-
-## Feature gate
-
-`use_printer_agents` enables printer-agent routing. With the gate off,
-agent code must have no observable effect. Released profiles can already
-contain `printer_agent` values, so activating an agent while the gate is
-off would change existing user behavior merely by loading a profile.
-
-Keep the gate at the routing call sites. Do not fold it into general Bambu
-vendor checks: slicing and hardware decisions such as AMS, lidar, bed
-types, and G-code flavor still describe printer capabilities, not the
-selected printer agent.
-
-## Backward compatibility
-
-`printer_agent` remains a `coString`, even when the ID is currently
-unregistered. A preset may refer to an optional plugin that is not
-installed. The unknown string must load, remain unchanged, and round-trip
-without making the preset dirty. The UI may show it as missing, but must
-not rewrite it to a fallback ID.
-
-Keep the feature gate's off-path behavior unchanged, preserve stored agent
-IDs, and treat Bambu-shaped payloads as a compatibility contract.
-
-The reason these three are grouped is that each looks like a local code
-change and is not. Switching which printer agent handles a preset edits no
-profile and no project file, so it reads in review as contained to the
-agent layer. But a user's stored presets and `.3mf` projects already carry
-`printer_agent` values and were saved against the Bambu-shaped payload. So
-a change that is local in the code is not local in effect: it reaches
-every previously saved file. That is why the gate must be inert when off,
-an unknown ID must survive untouched, and the payload shape is treated as
-a contract rather than an implementation detail.
-
-## Threading rule
-
-Agents may perform network work on their own threads, but all mutations of
-Device Manager maps and `MachineObject` UI state must run on the UI thread.
-Queue incoming status before it reaches `parse_json()` or any operation
-that adds, removes, selects, or changes a device. This prevents races
-between background network callbacks and UI reads. For example, when a status
-callback arrives on an agent's network thread, queue it to the UI thread
-before it reaches `MachineObject::parse_json()` or changes a device map or
-selection. The Device tab reads those same structures on the UI thread, so
-parsing or adding, removing, or selecting a device from the network thread
-could race with that read.

-Two render surfaces, never one:

-
-## Bambu
-
-Bambu playback uses `wxMediaCtrl2` and the native Bambu media pipeline.
-The URL comes from the Bambu LAN or cloud path, not from
-`IPrinterAgent`. A printer agent should not attempt to force a Bambu URL
-through the Moonraker or WebView path.
-
-## Moonraker live view
-
-On connection, the Moonraker agent obtains the first enabled webcam URL
-from `/server/webcams/list`. An absolute HTTP URL is used directly. A
-relative URL is resolved against the printer's host web root, with the
-Moonraker API port removed. This is necessary because a relative webcam
-path may exist on the printer's web server but not on the API port.
-
-The connection generation guards the result. A late request must not
-replace the URL after the user has selected a different printer. Failed
-discovery clears the URL, which prevents a prior camera from remaining
-visible on a printer with no camera.
-
-The agent places the discovered URL in its status payload. The Device
-panel renders it in `wxWebView`. It reloads only when the URL changes and
-resets the camera-start timestamp at that point. Reloading every update
-would loop indefinitely for endpoints that redirect, so an unchanged URL
-is shown again without calling `LoadURL()`.
-
-The trade-off is intentional: a WebView that loses an unchanged stream
-does not automatically reload. Camera controls beyond live viewing remain
-out of scope for Moonraker. Recording, timelapse, settings, and virtual
-camera are Bambu-oriented features and must not be presented as supported
-merely because live view works.
-
-## Snapmaker polling view
-
-Snapmaker overrides normal webcam discovery. It writes a per-printer local
-HTML page that polls the printer's `monitor.jpg` with a cache-busting URL.
-Each next request starts after the prior image loads or fails, preventing
-requests from piling up on a slow printer. A raw snapshot URL is not used,
-because it would display one frozen frame instead of a live-looking view.
-
-The printer must be asked to start its camera capture task. While the
-camera view is visible, the Device panel requests this at first display
-and then attempts another request every 300 seconds. Other agents reject
-the command quietly, so the common timer does not create an error for
-Bambu or ordinary Moonraker.
-
-The Snapmaker command is sent from a detached thread because the request
-can block on socket I/O and the printer responds over a different channel.
-This avoids blocking the UI but leaves a raw-`this` lifetime risk: the
-agent can be destroyed while the detached operation still refers to it.
-Do not extend this path without addressing that ownership boundary.
-
-The wrapper is written below the application cache with a name derived from
-the printer IP. The source contains no cleanup path for those files, so they
-can accumulate as different printer IPs are used. This is source-derived and
-was not reproduced during this rewrite.
-
-Source code proves 300-second renewal attempts only. The long-running
-behavior of the shipped polling and renewal cycle has not yet been tested.
-Do not claim that the attempt renews an active capture task or that it
-prevents camera expiry until hardware verification establishes both.
-
-## Maintenance checklist
-
-- Keep the three ownership models separate.
-- Preserve host-root resolution for relative Moonraker URLs.
-- Keep generation guards and stale-URL clearing on every discovery path.
-- Reload WebView content only after a URL change.
-- Reset the camera-start timestamp when the camera URL changes.
-- Treat Moonraker as live-view-only and Snapmaker lifecycle behavior as
-  not yet verified beyond the observed renewal attempts.

-# Connection and status
-
-*Owns the runtime sequence in order: selecting an agent and machine,
-starting a connection, receiving status, sending commands. Defers the
-structural rules those steps must obey - ownership, no-fallback, unknown
-IDs, threading - to [Architecture](architecture.md), and cites them at the
-point where they bite.*
-
-## The four runtime concepts
-
-Keep these concepts separate when tracing a connection problem:
-
-- A preset stores an agent ID and printer address.
-- `NetworkAgent` holds the active printer agent for that agent ID.
-- `MachineObject` represents the selected printer at that address.
-- Freshness and status-confirmed readiness are separate states.
-
-An agent ID selects a printer agent implementation. A device ID selects one
-printer within that implementation.
-
-A non-Bambu printer reaches the machine list through **Bind with Access
-Code**, the tile in the Device tab's machine-select popup. The user enters
-an address and an access code, `bind_detect()` probes the address before
-any connect, and `DeviceManager::insert_local_device()` creates the
-`MachineObject`. For the Moonraker family the address itself becomes the
-device ID: `MoonrakerPrinterAgent::bind_detect()` seeds `dev_name` and
-`dev_id` from the entered address, so an unreachable or unnamed printer
-still shows up as its IP rather than blank.
-
-Binding is the only route for that family. `MoonrakerPrinterAgent::start_discovery()`
-deliberately announces nothing, because a partial discovery implementation
-would populate the machine list with stale hosts. Bambu is the exception:
-it has its own discovery identity and does not use the address as an ID.
-
-`DeviceManager::selected_machine` is only a selected ID. It can name no
-resolvable object. `get_selected_machine()` answers whether an object is
-actually available. `set_selected_machine()` accepting an ID therefore
-does not prove the printer is connected. The selected ID can remain when its
-object is unavailable, so connection state must come from the object itself.
-
-## Selecting the agent and machine
-
-`GUI_App::switch_printer_agent()` reads the edited printer preset and
-resolves its stored agent ID through `NetworkAgentFactory`.
-
-1. An empty stored ID is a legacy sentinel. It resolves to `bbl` for a
-   Bambu vendor preset and to `orca` otherwise.
-2. If that effective ID is registered, the factory provides the matching
-   printer agent implementation.
-3. Clear the live printer agent only when a nonempty stored ID is unregistered
-   or the factory cannot construct the matching registered agent.
-4. When the active printer agent changes, clear the current selection, user
-   selection, stale device discoveries, sidebar state, and AMS state before
-   installing the replacement.
-5. Select the preset's address-derived machine for non-Bambu agents.
-
-The lifetimes are easier to see than to read. Note that the agent pointer
-can be unchanged while the machine still must be re-selected - that is the
-trap in the same-agent path below:

-> **Do not use the first available machine as a fallback** (rule owned by
-> [Architecture](architecture.md), Runtime objects and ownership). It
-> connects to a printer the user did not choose, including one owned by a
-> different printer agent.
-
-The same-agent path is important too. Two presets can use one agent type
-but point at different addresses, and the factory caches one agent per ID,
-so switching between them returns the same pointer and would otherwise
-skip reselection entirely. Re-select the machine whenever the preset's
-address changes, even when the factory returned the same active agent.
-Otherwise status and filament work can continue against the previous
-printer.
-
-Note: this is a legacy coupling, not the primary workflow. It reads an
-address stored on the printer preset itself (`print_host` and
-`printhost_port`, named here only so the keys can be found in the code)
-and derives a device ID from it with `dev_id_from_address()`. Those keys
-predate printer agents and are edited through `PhysicalPrinterDialog`,
-which despite its name writes the printer preset rather than a
-`PhysicalPrinter` object - that object is no longer constructed. Printers
-normally arrive through Bind with Access Code instead, which does not
-touch the preset. Both routes end at `insert_local_device()`, so they must
-agree on the device ID: `dev_id_from_address()` strips the URL scheme and
-drops an empty port, while the bind path stores the address as the user
-typed it.
-
-The unknown-`coString` compatibility rule belongs to `architecture.md` under
-Backward compatibility. Keep a nonempty unknown `printer_agent` ID unchanged
-and display a missing state if needed; do not rewrite it during plugin unload
-or choose an arbitrary replacement, so the preset can round-trip while its
-plugin is temporarily unavailable.
-
-## Starting a connection
-
-Machine selection causes `MachineObject::connect()` to invoke the active
-agent's `connect_printer()` with the selected address and effective access
-code. A success return means that the connection attempt started. It does
-not mean that the printer is ready or that a status stream is alive.
-
-Moonraker-family agents must force HTTP. Moonraker and print-host
-installations commonly serve plain HTTP, while the generic machine path
-can request TLS by default. Passing that default through turns a valid
-connection into an HTTPS request the printer will refuse. The agent therefore
-must keep the connection on HTTP unless its protocol support changes
-deliberately and is verified.
-
-## Access codes: four coordinated slots
-
-One effective access code can live in four places:
-
-| Slot | Location | Purpose |
-| --- | --- | --- |
-| Device runtime | `MachineObject::access_code` | Code learned from the device. |
-| User runtime | `MachineObject::user_access_code` | Code entered by the user. |
-| Device config | `access_code[dev_id]` | Persisted device value. |
-| User config | `user_access_code[dev_id]` | Persisted user value. |
-
-The effective code prefers the user value when present, then the device
-value. Keep user input in the user path and device replies in the device
-path. Crossing those paths obscures which value should win.
-
-`set_access_code()` deliberately does not save configuration immediately.
-Device replies and polls can update it often; forcing a full config write
-for each message adds unnecessary work. The normal deferred config save
-persists dirty state later. Do not add an eager save just to make this one
-path symmetric: device replies and polls update it often, so a config
-write per message is wasted work.
-
-> **Do not erase the user access code when a printer connects.** On the
-> LAN reselection path that code can be the only credential that lets the
-> machine pass the access check and receive the status or access-code
-> reply that would refresh it, so erasing it at connection time can leave
-> the machine permanently unable to receive updates. A failed connection
-> is the place to handle a proven bad credential.
-
-## Receiving status
-
-An agent receives native status, translates it to the existing payload
-shape, and dispatches it to the matching `MachineObject`. The object
-parses the payload and records when it last received an update.
-
-Readiness is four states, and three of them look connected:
-

-selection, or `MachineObject` state, because network callbacks may run in a
-worker thread and mutating these structures there races with the Device tab.
-
-## Sending commands
-
-`MachineObject` builds the established command JSON and sends it through
-the active `NetworkAgent`. The agent translates it or returns an explicit
-unsupported result. It must not report success when no translation exists.
-
-The `pushing` command exception belongs to `architecture.md` under Commands
-and unsupported work. It asks for status, and a working status stream already
-supplies it, so accepting it avoids false unsupported warnings from the Device
-Manager's repeated keepalive.
-
-## Maintainer constraints
-
-- Preserve same-agent reselection by address, because an agent type can
-  serve more than one printer.
-- Preserve the null-agent, no-fallback, and unknown-`coString` rules in
-  `architecture.md`; selection must remain an explicit user or preset choice,
-  and stale state must not belong to a replacement printer agent.
-- An empty value is the legacy Bambu-or-Orca sentinel, not a missing printer
-  agent.
-- Preserve deferred access-code saves and the no-on-connect-erase rule;
-  they prevent excessive config writes and credential-driven status loss.
-- Keep Moonraker connections HTTP-only unless the agent's protocol support
-  changes deliberately and is verified.
-- Do not treat freshness as proof that status arrived; wait for
-  status-confirmed readiness. The UI-thread mutation rule is in
-  `architecture.md` under Threading rule.

-
-Filament support has three separate stages. A successful first stage does
-not mean that a selected mapping will be delivered to the printer.
-
-Stage 3 is where the two paths diverge, and only one of them reaches the
-printer:

-
-    SRC --> ACQ --> ST --> SEL --> PAR
-    PAR -- Qidi --> QIDI --> OK
-    PAR -- every other target --> BASE --> DEAD
-```
-
-## 1. Acquire printer state
-
-`FilamentSyncMode` declares how the UI obtains filament state:
-
-| Mode | Meaning |
-| --- | --- |
-| `subscription` | A status stream keeps the state current. |
-| `pull` | The UI must request state before it can use it. |
-| `none` | The agent has no usable filament state. |
-
-Moonraker uses `pull`. Its ordinary status stream does not supply the
-filament data used by this UI. In particular, `lane_data` is a Moonraker
-database namespace, not a printer object that the existing subscription
-can follow. Changing Moonraker to `subscription` would suppress the pull
-that actually populates the UI.
-
-The agent first reads `lane_data`, which can describe AFC and newer Happy
-Hare installations. If that is unavailable, it reads the classic Happy
-Hare `mmu` object. Those response shapes are source-supported but not yet
-verified against current Happy Hare and AFC installations.
-
-The current parser expects lane values as strings and silently skips
-numeric values. Whether current AFC or Happy Hare installations emit
-numeric lane values is unverified.
-
-The received lanes are converted into a Bambu-shaped model so existing
-AMS UI can render them. The model groups numeric lane indexes into
-synthetic groups of four slots and passes the result through
-`ParseV1_0`. This is a UI compatibility adapter, not evidence that the
-printer has a Bambu AMS.
-
-Pull state can be stale. The Send dialog can build a mapping from the
-current `DevFilaSystem` without refreshing it first, and a failed pull can
-leave older state visible. Do not represent a displayed lane list as a
-fresh printer read unless the call site just performed the pull.
-
-## 2. Select a mapping
-
-The Send dialog matches each project filament to a compatible reported
-slot. It rejects a mismatched material type and then prefers compatible
-slots according to the existing mapping rules. The result is carried in
-the legacy linear mapping, the explicit AMS-and-slot mapping, and mapping
-metadata for the job.
-
-Treat lane numbers as printer contracts. A numeric lane index is used as a
-slot index in the synthetic four-slot view, so an incorrect numbering
-assumption can select the wrong physical lane.
-
-The material identity code also retains a defect: ABS and ASA can be
-shown as PLA when profile identifiers collide. This is not fixed here,
-and multi-color mapping has not received hardware verification.
-
-## 3. Deliver the mapping at print time
-
-`PrintJob` copies the selected mappings into `PrintParams`, but base
-Moonraker does not read those fields when it uploads and starts a print.
-For plain Moonraker, Happy Hare, and AFC targets using that base path, a
-correct-looking mapping in the UI is therefore not delivered to the
-printer. The print runs using the printer's own loaded-lane behavior.
-
-Qidi is the implemented exception. Its agent writes its own box mapping
-before starting the print. That is a Qidi-specific delivery contract, not
-a generic Moonraker solution.
-
-There are deliberately no guessed Happy Hare or AFC write macros. Their
-macro and variable names are defined by printer-side configuration, so a
-guessed command could silently do nothing or control the wrong setup. Add
-a delivery path only after verifying the exact contract against upstream
-documentation or a real printer.
-
-## Maintenance checklist
-
-- Keep Moonraker in `pull` mode while `lane_data` remains pull-only.
-- Refresh or clearly surface stale state before relying on Send-dialog
-  mappings.
-- Do not claim base Moonraker honors mappings until it consumes them at
-  print time.
-- Preserve Qidi as a distinct delivery implementation.
-- Verify lane numbering, material identity, and multi-color behavior on
-  hardware before expanding the mapping contract.

-# Python printer-agent plugins
-
-*Owns the plugin bridge: the implementation contract, registration and
-lifetime, and the audit scope. Defers what the agent must do once live to
-[Architecture](architecture.md) and
-[Connection and status](connection-and-status.md).*
-
-Python printer agents use the current capability bridge. They do not use a
-separate adapter or a Moonraker-specific plugin path.
-
-## What an agent must implement
-
-Not overriding a member of `IPrinterAgent` has four different
-consequences depending on which tier it is in. This is the whole plugin
-contract:
-
-| Tier | Members | Consequence of not overriding |
-| --- | --- | --- |
-| Pure virtual | `connect_printer`, `disconnect_printer`, `send_message_to_printer`, the `start_*` print operations, `start_discovery`, `bind`, `bind_detect`, `unbind`, the callback setters, `set_cloud_agent`, `get_agent_info`, and the rest of the pure surface | Compile error |
-| Concrete, succeeds | `start_subscribe`, `stop_subscribe`, `add_subscribe`, `del_subscribe` | Silently returns `BAMBU_NETWORK_SUCCESS` |
-| Concrete, declines | `command_ams_refresh_rfid`, `command_ams_calibrate`, `command_ams_select_tray`, `command_start_camera` | Silently returns `ORCA_NETWORK_ERR_CMD_NOT_SUPPORTED` |
-| Concrete, inert | `get_filament_sync_mode`, `fetch_filament_info` | Reports `FilamentSyncMode::none` and `false` - no filament capability at all |
-
-The refusal tier is deliberate: those commands carry Bambu-dialect G-code
-in their bodies, so the honest default is a refusal that
-`MachineObject::publish_json()` turns into a dialog. The success tier is
-equally deliberate - a printer whose status already streams needs no
-subscription call.
-
-> **Do not assume a missing override quietly inherits useful behavior, and
-> do not assume it fails loudly either.** Only the first tier fails at
-> compile time. The second silently reports success, the third silently
-> declines, and the fourth silently reports no filament capability.
-
-## The plugin contract
-
-A plugin subclasses `printer_agent.PrinterAgentBase`, the Python binding for
-`PrinterAgentPluginCapability`. The capability itself is the live native
-`IPrinterAgent`; there is no intermediate protocol adapter, because
-`PrinterAgentPluginCapability` inherits both `PluginCapabilityInterface`
-and `IPrinterAgent` directly.
-
-`get_type()` stays a `PluginCapabilityInterface` method and
-`set_cloud_agent()` remains the native host injection point. A plugin must
-implement the pure connection, communication, discovery, binding, print,
-callback-registration, and filament-refresh operations. The certificate,
-bind-ticket, HMS-snapshot, and user-selected-machine members are pure too;
-the table above abridges the list.
-
-The only tracked Python printer-agent implementation is the BBL plugin. There
-is no Python Moonraker printer agent in the current source tree. Moonraker is
-implemented by the built-in C++ class.
-
-## Registration and lifetime
-
-When an enabled plugin advertises a printer-connection capability, the factory
-gets its `AgentInfo` and registers a factory under `AgentInfo.id`. This is the
-same registry used for built-in agents.
-
-Two similarly named structs are involved, and they are not the same thing.
-`AgentInfo` is what the agent says about itself; `PrinterAgentInfo` is the
-registry's entry about it:
-
-```mermaid
-classDiagram
-    class AgentInfo {
-        <<returned by the agent via get_agent_info>>
-        string id
-        string name
-        string version
-        string description
-    }
-    class PrinterAgentInfo {
-        <<the registry entry>>
-        string id
-        string display_name
-        string plugin_identifier
-        PrinterAgentFactory factory
-    }
-    class PrinterAgentFactory {
-        <<std::function>>
-        takes cloud_agent and log_dir
-        returns shared_ptr~IPrinterAgent~
-    }
-    class NetworkAgentFactory {
-        <<all static>>
-        register_printer_agent(id, display_name, factory)
-        create_printer_agent_by_id(id, cloud_agent, log_dir)
-        clear_printer_agent_cache()
-        register_python_printer_agent(plugin_key, capability_name)
-        deregister_python_printer_agent(plugin_key, capability_name)
-    }
-
-    AgentInfo ..> PrinterAgentInfo : id becomes the registry key
-    PrinterAgentInfo *-- PrinterAgentFactory
-    NetworkAgentFactory o-- PrinterAgentInfo : one entry per ID
-    PrinterAgentFactory ..> PrinterAgentPluginCapability : weak reference
-```
-
-`plugin_identifier` is empty for built-ins and
-`<plugin_key>;<uuid>;<capability_name>` for plugins - that is how the
-registry tells the two apart at deregistration time. Built-in IDs are the
-constants `ORCA_PRINTER_AGENT_ID` and `BBL_PRINTER_AGENT_ID`.
-
-Agent IDs are global. A plugin cannot replace a built-in agent or another
-plugin with the same ID. Registry rejection is unconditional. The conflicting
-capability is disabled and the user is shown the conflict only when `wxTheApp`
-exists and the app is not closing. Re-registering the same plugin capability
-is allowed so a reload can replace its factory with the current capability
-instance.
-
-The registered factory holds a weak reference to the capability. If the plugin
-has already gone away, creation returns null instead of reviving a destroyed
-Python object. Callers must treat that as no active printer agent.
-
-On deregistration, the factory removes the registry entry and cached agent,
-disconnects a cached agent, and clears the live agent if it has the same ID.
-This order prevents `NetworkAgent` from retaining a Python implementation
-whose module is about to unload. The current path is UI-thread oriented. Raw
-pointer hazards become relevant only if deregistration moves to another thread
-without adding synchronization around the GUI-held active-agent handle.
-
-## Device-tab integration
-
-Plugins share the native Device tab with built-in agents. There is no
-printer-agent API for adding custom Device-tab panels and no plugin-owned
-`MachineObject` to populate directly.
-
-Instead, the plugin supplies the same callbacks as any `IPrinterAgent`. Its
-status messages must use the Bambu-shaped payload that `MachineObject` already
-parses. If a required field is absent, the shared native UI shows its default
-or incomplete state. A custom protocol is acceptable inside the plugin, but
-its boundary with the app must perform this translation.
-
-## Python calls, errors, and audit scope
-
-The C++ trampoline acquires the Python GIL, invokes each pure virtual override,
-logs a Python exception, and rethrows it. A missing override is a separate
-C++ pure-virtual failure, not a logged Python traceback. Python construction
-also bypasses the virtual trampoline, so the bridge logs a constructor failure
-at the construction boundary.
-
-Plugin-created threads need their own exception handling. An exception raised
-there does not cross the C++ trampoline; it reaches Python's thread exception
-handling and is recorded through redirected Python standard error.
-
-The audit hook is defense in depth, not a sandbox. Current printer-agent
-trampoline calls use loading audit mode. In that mode, normal reads are
-allowed, only some file writes are checked against allowed roots, and many
-operations are outside the policy, including network access and process
-creation. Work that runs outside an active trampoline scope, including a
-plugin-created thread, has no attributed plugin context and is allowed by
-default. Do not treat this mechanism as permission to run untrusted code.

-# Printing through printer agents
-
-*Owns the send path: connection choices, preflight, upload, start, and the
-two recovery flows. Defers filament mapping delivery to
-[Filament synchronization](filament.md), which is a separate contract even
-though it is applied at print time.*
-
-This chapter describes the printer-agent send path. It is separate from
-the older print-host implementation, even when both target Moonraker.
-Keep the paths separate unless their contracts and failure handling can
-be deliberately reconciled.
-
-## Connection choices
-
-Three connection paths are in use:
-
-| Target | Connection path | Use |
-| --- | --- | --- |
-| Native Bambu | Custom TLS tunnel on port 6000 | Send and optional eMMC preflight |
-| Bambu Python agent | Implicit FTPS on port 990 | Upload and Bambu preflight fallback |
-| Moonraker family | HTTP | Upload and start print |
-
-The Bambu connection paths are independent. Selecting one does not prove that
-the other is available. The Moonraker agent uploads with a multipart
-request to its `gcodes` storage and then starts the uploaded filename;
-it does not reuse the legacy `Moonraker` print-host class.
-
-## Bambu native tunnel
-
-The native tunnel depends on the versioned networking DLL and its
-file-transfer module. `InitFTModule()` is a single-owner initialization:
-it rejects a second call. Any future shared initialization must therefore
-be idempotent, while `BBLNetworkPlugin` remains the single teardown owner.
-It must call `UnloadFTModule()` before freeing the DLL, otherwise the
-module's function pointers can point into unloaded code.
-
-There is currently an initialization gap: selecting a printer agent does
-not initialize this module. It is initialized only when the
-`installed_networking` option causes the native BBL network plugin to
-initialize. Calls to the tunnel must continue to fail safely until that
-path has initialized the module. The Send UI catches this failure and
-reports an initialization error instead of letting an exception leave a
-wx event handler.
-
-## Bambu FTPS upload
-
-The Python Bambu agent uses implicit FTPS on port 990. Its live upload
-path closes the data connection, then waits at most two seconds for the
-control response with `voidresp()`. A `TimeoutError` is accepted as a
-completed transfer. An `error_reply` is also accepted when its reply
-begins with `200`. This is the behavior to preserve.
-
-Do not describe the path as using TLS `unwrap()`: the live construction
-does not enable it. Enabling it without a bounded wait could hang while
-waiting for the peer's TLS close notification. The current timeout-based
-handling has not been verified on hardware against every printer and FTP
-server combination.
-
-## Print preflight and recovery
-
-For normal LAN prints, `PrintJob` performs a preflight before the real
-send. When eMMC is eligible it tries the native tunnel, then it sends a
-small `verify_job` upload through the selected agent. The latter is a real
-upload, not a special protocol command. Non-Bambu agents therefore upload
-the probe too.
-
-> **Do not re-enable eMMC by default** without hardware coverage for the
-> affected devices. It is opt-in because the tunnel can hang during upload
-> on some printers.
-
-The whole send, including the thread hop and the recovery fork:
-
-```mermaid
-sequenceDiagram

-    participant J as PrintJob (worker)
-    participant A as Selected IPrinterAgent

-        A->>P: Upload, then request print start

-        A-->>UI: Result from the reported print state
-    else Upload fails
-        J-->>UI: Failure callback, marshalled to the UI thread
-        Note over UI: Re-resolve the machine here.<br/>Never reuse a machine pointer captured<br/>on the worker - agent or machine may have changed
-        alt Printer still connected
-            UI->>UI: Explain that storage upload failed
-        else Printer disconnected
-            UI->>UI: Open the IP or access-code flow
-        end
-    end
-```
-
-An upload failure and a disconnected printer need different recovery:
-
-| Condition | UI response |
-| --- | --- |
-| Printer is still connected | Explain that storage upload failed. |
-| Printer is disconnected | Open the IP or access-code flow. |
-
-> **Do not retain a machine pointer from a worker callback.** The callback
-> that chooses between these two outcomes runs on the UI thread and
-> re-resolves the machine there, because the selected agent or machine can
-> change first. The connection check is adequate for choosing the message,
-> but is not a strong enough signal to authorize a reconnect.
-
-## Moonraker upload and start
-
-`MoonrakerPrinterAgent` uploads through Moonraker HTTP, then requests the
-print start separately. The start endpoint may keep its response open
-while the printer prepares the job. A timeout after that request is not
-automatically proof that the start failed: the agent checks the reported
-print state before deciding the result.
-
-The legacy print-host Moonraker path implements its own upload and start
-logic. It is not the agent path and should not be changed as an implicit
-side effect of agent work.
-
-## Maintenance checklist
-
-- Test the selected connection path, not just another path on the same
-  printer.
-- Preserve cancellation and progress callbacks across upload and start.
-- Treat `verify_job` as an actual upload when estimating storage effects.
-- Keep eMMC opt-in until its hanging behavior is resolved and verified.
-- Keep the connected-upload-failure dialog distinct from the disconnected
-  recovery flow.

-# Testing and troubleshooting printer agents
-
-*Owns evidence grades, the automated and manual verification passes, and
-the open-defect register. Every "not hardware-verified" note elsewhere in
-this guide resolves to a grade defined here.*
-
-This page describes how to assess a printer-agent change without treating
-source inspection as a hardware result. Use the
-[manual checklist](reference/manual-checklist.html) for a repeatable live-printer
-pass, and use the [capability matrix](reference/capability-matrix.md) to decide
-which cases apply to the agent being changed.
-
-## Evidence grades
-
-Keep these grades separate in reviews and release notes.
-
-- Source-inspected - the current implementation was read. It establishes
-  intended behavior, not printer compatibility.
-- Automated - a targeted test ran. It covers its inputs and assertions, not a
-  printer, firmware version, or network failure that it does not model.
-- Hardware-verified - the stated behavior was observed on a named class of
-  live printer. Record the model, firmware, configuration, and result with the
-  test evidence.
-
-Do not call a capability supported by hardware solely because the code compiles or
-a unit test passes. Conversely, a hardware observation should not be generalized
-to every Moonraker-family printer without checking its configuration.
-
-## Carried hardware evidence
-
-Prior hardware sessions verified direct Moonraker-family connection, live
-WebSocket status, and jog on both a Qidi/Moonraker printer and a generic
-Moonraker box. The jog moved the printer but could leave relative positioning
-active. This evidence establishes the Moonraker-base and Qidi grades in the
-capability matrix. It was carried into this rewrite and was not rerun here.
-
-It does not establish those behaviors for Creality or Snapmaker, and it does
-not cover Qidi-specific filament discovery, box mapping, or print wrappers.
-
-## Build and automated tests
-
-Run the smallest relevant test target first, then broaden the run if the change
-crosses shared agent, plug-in, or Device-tab code. Set
-`<configured-build-dir>` to the CMake build tree that was already configured for
-the compiler, generator, and build type you intend to use. Do not replace it
-with the source directory or assume a `build` subdirectory exists.
-
-```powershell
-cmake --build <configured-build-dir> --config RelWithDebInfo --target slic3rutils_tests
-cmake --build <configured-build-dir> --config RelWithDebInfo --target printer_agent_plugin_tests
-ctest --test-dir <configured-build-dir>/tests/libslic3r --output-on-failure
-```
-
-`--config RelWithDebInfo` is needed for multi-config generators such as Visual
-Studio. Omit it only when the configured generator is single-config and its
-build type was selected at configure time. Parallel-build options belong to the
-generator: for example, pass `--parallel 6` to CMake when the generator
-supports it, or use the generator's own trailing arguments only when that
-generator documents them. Do not combine a changed working directory, a
-generator-specific flag, and an assumed build-tree layout in one command.
-
-On Windows, start from an MSVC developer environment. A shell without the MSVC
-include paths can fail in dependencies before it compiles Orca code, with errors
-such as `C1083: Cannot open include file: 'stddef.h'`, `'time.h'`, or `'cstdint'`.
-Those signatures are environment failures, not evidence against the agent change.
-
-If a machine exhausts MSVC precompiled-header memory, use the documented lower
-parallelism command:
-
-```powershell
-cmake --build <configured-build-dir> --config RelWithDebInfo --target slic3rutils_tests --parallel 6
-```
-
-Errors such as `C3859: Failed to create virtual memory for PCH` and `C1076:
-internal heap limit reached` are machine-specific resource failures. If a build
-appears hung and file operations are blocked, inspect for idle `cl.exe` processes
-holding locks before changing source.
-
-Relevant automated coverage includes:
-
-- `tests/slic3rutils/test_qidi_printer_agent.cpp` validates malformed and null
-  Qidi slot responses without throwing.
-- `tests/slic3rutils/test_printer_agent.cpp` checks the public printer-agent
-  surface, including filament-sync mode exposure.
-- `tests/slic3rutils/test_printer_agent_plugin.cpp` exercises plug-in
-  registration, replacement, conflict handling, and deregistration.
-
-Do not present a historic test count, failure count, or skipped-test count as the
-current state. Run the command above and attach its own output when a current
-result is needed.
-
-## Manual hardware verification
-
-Use a small, disposable model and a printer that can safely accept the actions.
-The checklist groups the work in the order below.
-
-1. Confirm the printer accepts its configured URL and API key, then select it in
-   the Device tab. Verify a fresh status update, not merely a successful connect
-   return code.
-2. Observe temperatures, targets, fan state, print state, filename, progress,
-   elapsed time, and axis homing while the printer changes state.
-3. Exercise safe idle controls first: home, bed and nozzle temperature, and a
-   harmless G-code command. Verify the printer's action as well as the UI
-   response.
-4. Send a small file without starting it, then start a small print. Once the
-   print is active, pause it, confirm the printer and UI both enter a paused
-   state, resume it, and confirm both return to printing. Cancel only after
-   observing an active or paused print, then confirm that the printer stops and
-   the UI leaves that state. Cancel an upload and retry a missing input so that
-   failure handling is observed too.
-5. For Moonraker command workers, send three harmless, uniquely marked commands
-   while a proxy, network shaper, or request log introduces or records latency.
-   Pass only if the printer-side log records the markers in the same order they
-   were queued. Record the latency method and the observed order.
-6. For a material system, verify populated slots, empty slots, material, colour,
-   refresh after a change, and cleanup when the system is absent or filament is
-   removed. The latter must remove obsolete slot or material data from the UI.
-   Do not infer write support from read support.
-7. For Qidi, use a compatible single-nozzle slice and Send it while the Device
-   tab has no reported nozzle diameter or type. Pass only if Send proceeds past
-   preflight without `PrintStatusNozzleDataInvalid`; record any reported
-   diameter/type and any mismatch message separately. This checks the intended
-   tolerance for missing identity data, not that a mismatched known nozzle is
-   safe.
-8. Verify the camera only on hardware that advertises or implements it. Check
-   that frames advance, switching printers starts the newly selected camera, and
-   closing or changing the view does not leave misleading stale output. For
-   Snapmaker, also test immediately before and after 300 seconds in an
-   uninterrupted view. The expected renewal result is unknown until hardware
-   evidence exists. Swap agents and shut down the app after the camera cases to
-   exercise teardown around the detached callback's raw-`this` lifetime risk.
-9. For Moonraker thumbnails, test a reused filename after its thumbnail changes,
-   responses that use `thumbnail_path` and `relative_path`, and a thumbnail in a
-   subdirectory below the G-code root. Record the endpoint payload and displayed
-   image for each case.
-10. Disconnect and reconnect the printer, then confirm that new status messages
-    still reach the UI. A reconnect completion alone is insufficient evidence.
-11. Test network and response failures for discovery, status, G-code, upload,
-    and print start. For each operation, exercise HTTP 401, 404, and 500,
-    invalid JSON, and a refused socket with a controlled proxy or test server.
-    Each case must fail clearly or offer a retry, without a crash or a false
-    success. Record the operation, injected failure, UI result, and any retry.
-
-For Moonraker, record whether the thumbnail endpoint returns the response shape
-the agent expects. That response has not yet been verified across a live
-Moonraker deployment.
-
-## Troubleshooting by symptom
-
-### Connection appears successful but the Device tab stays stale
-
-Treat status freshness as the connection result. Enable `ORCA_NETWORK_DEBUG` and
-look for a new `parse_json: dev_id=` entry after the connection or reconnection.
-The unresolved reconnect-delivery problem can complete the second connection
-without delivering any new parsed messages. Capture an instrumented second
-connection before changing dispatch or message-delay logic, because both remain
-plausible causes.
-
-Check identity too. One path can use a bare IP address while another uses
-`host:port`; configuring a port can therefore create two machine objects. Do not
-diagnose a duplicate as a printer-agent failure until the identities are
-compared.
-
-### A control reports success but the printer did not change
-
-First establish that the command has a documented translation in the capability
-matrix. Unsupported commands are deliberately rejected rather than silently
-accepted. For Moonraker, queued controls are asynchronous, so wait for the
-printer-side result and capture the request or log before concluding it was lost.
-
-Moonraker jog is a special case. The current path can leave the printer in
-relative positioning mode after a jog. Do not use it as a general verification
-control until it is changed to save state, issue `G91` and the move, then restore
-state with `SAVE_GCODE_STATE` and `RESTORE_GCODE_STATE`. Extruder-relative moves
-use a separate `M83` path.
-
-### A thumbnail is missing or belongs to an earlier print
-
-The thumbnail lookup accepts both `thumbnail_path` and `relative_path`, but the
-live endpoint response is not yet verified. The cache is keyed by filename, so
-reusing a common name can retain the previous image. Test a distinct filename
-before changing the lookup. Paths below the G-code root also need live coverage
-for the `relative_path` fallback.
-
-### Filament looks stale, blank, or does not follow an edit
-
-Moonraker-family agents use pull-mode filament sync. Verify the pull request and
-the resulting Device-tab update rather than expecting a subscription callback.
-Read-side discovery does not establish load, unload, slot-setting, or Auto Refill
-support. Happy Hare and AFC macro names are printer-side configuration; do not
-guess them. A guessed macro can silently do nothing or issue the wrong action.
-
-### A Python agent disappears or cannot be enabled
-
-Check its agent ID first. A duplicate ID is rejected and the conflicting
-capability is disabled rather than auto-promoted later, because automatic
-promotion could change the active printer implementation without user intent.
-Reload and teardown also need a live check: registration tests cover lifecycle
-logic, but a plug-in can still be exposed to API drift or a teardown race in a
-real session.
-
-## Known defects and safeguards
-
-- Reconnect delivery remains unresolved. Instrument the second connection before
-  attempting a fix; the observed failure is stale data after a completed reconnect.
-- Moonraker jog can leave relative mode active. Keep the future state-save and
-  restore sequence together so the jog cannot affect later G-code positioning.
-- Qidi's nozzle-data Send-preflight tolerance for unreported diameter and type
-  has not received a hardware verification.
-- A configured `host:port` can coexist with a bare-IP machine identity. This can
-  duplicate devices and confuse selection.
-- Moonraker thumbnail caching can show an old image when a filename is reused.
-- Moonraker filament data can be stale, and its pull/read path does not provide
-  safe generic write-side MMU operations.
-- Duplicate plug-in agent IDs are rejected. There is no automatic fallback to a
-  losing capability after the winner unloads.
-- Plug-in implementations can drift from the Python printer-agent API. Treat an
-  import or interface error as a plug-in compatibility issue until proved otherwise.
-- Snapmaker camera callbacks can outlive their view during agent replacement or
-  shutdown because the detached path retains a raw `this` pointer. Treat a crash
-  or stale callback during those transitions as a source-derived use-after-free
-  risk until the lifetime is made explicit.
-- Snapmaker writes an IP-specific local camera HTML file below the application
-  cache. The source contains no cleanup path, so residual files can accumulate
-  for each unique printer IP. This is source-derived and was not reproduced.
-
-## Not yet hardware-verified
-
-- Moonraker command-worker FIFO behavior under recorded or injected network
-  latency.
-- Moonraker thumbnail responses: reused filenames, `thumbnail_path`,
-  `relative_path`, and subdirectory paths.
-- Snapmaker camera behavior on a live U1: frames, renewal across a long-open
-  view including the 300-second boundary, switching between printers, agent
-  replacement, and shutdown teardown.
-- Whether Snapmaker's renewal cadence prevents a stale-frame interval. Do not
-  shorten it as a workaround without resolving the printer-side behavior first.
-- Creality CFS detection and preset scoring on a real printer.
-- Qidi Send preflight when firmware omits nozzle diameter and type.
-- Moonraker-family write-side MMU commands. They remain blocked on verified,
-  printer-specific macro contracts.
-
-## Background - source locations for maintainers
-
-The Moonraker command worker, status stream, print path, and thumbnail
-lookup live in `MoonrakerPrinterAgent`. Qidi maps its material box before routing
-to the Moonraker base. Snapmaker adds the camera start request and its snapshot
-page. Python agent registration and conflict handling live in
-`NetworkAgentFactory`.

-# Move `wxInspectable` into `DPIAware` — 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:** Move `wxInspector::wxInspectable` from individual leaf classes into the common `DPIAware<P>` template so every DPIAware widget is automatically inspectable and gets the inspector keyboard shortcut.
-
-**Architecture:** `DPIAware<P>` gains `wxInspector::wxInspectable` as a second base class and calls `SetupInspectorAccelerator(this)` in its constructor. `DPIDialog` and `MainFrame` drop their now-redundant `wxInspectable` inheritance and `SetupInspectorAccelerator` calls.
-
-**Tech Stack:** C++17, wxWidgets, wxInspector
-
-## Global Constraints
-
-- Build with `D:\VisualStudio\2026\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe`
-- Use `--config RelWithDebInfo` for all builds
-- Cross-platform: must compile on Windows, macOS, and Linux
-- Match existing code style: PascalCase classes, `#pragma once`
-- Do NOT commit files under `.superpowers/`
-- Do NOT commit `task.md`
-
----
-
-### Task 1: Move `wxInspectable` and `SetupInspectorAccelerator` into `DPIAware<P>`
-
-**Files:**
-- Modify: `src/slic3r/GUI/GUI_Utils.hpp:92` (DPIAware template — add wxInspectable base + SetupInspectorAccelerator call)
-- Modify: `src/slic3r/GUI/GUI_Utils.hpp:276` (DPIDialog — drop wxInspectable + SetupInspectorAccelerator)
-- Modify: `src/slic3r/GUI/MainFrame.hpp:96` (MainFrame — drop wxInspectable)
-- Modify: `src/slic3r/GUI/MainFrame.cpp:304` (MainFrame constructor — drop SetupInspectorAccelerator)
-
-**Interfaces:**
-- Consumes: Nothing (standalone refactor)
-- Produces: All DPIAware widgets automatically inherit `wxInspector::wxInspectable` and get Ctrl+Shift+I accelerator
-
-- [ ] **Step 1: Add `wxInspectable` to `DPIAware<P>` and call `SetupInspectorAccelerator`**
-
-In `src/slic3r/GUI/GUI_Utils.hpp`, line 92, change the base class:
-
-```cpp
-// Before:
-template<class P> class DPIAware : public P
-// After:
-template<class P> class DPIAware : public P, public wxInspector::wxInspectable
-```
-
-In the constructor body of `DPIAware<P>`, after `this->CenterOnParent();` (currently line 110), add:
-
-```cpp
-SetupInspectorAccelerator(this);
-```
-
-(`<wx/inspector/inspector.h>` is already included at line 23.)
-
-- [ ] **Step 2: Remove redundant `wxInspectable` and `SetupInspectorAccelerator` from `DPIDialog`**
-
-In `src/slic3r/GUI/GUI_Utils.hpp`, line 276, change:
-
-```cpp
-// Before:
-class DPIDialog : public DPIAware<wxDialog>, public wxInspector::wxInspectable
-// After:
-class DPIDialog : public DPIAware<wxDialog>
-```
-
-In the `DPIDialog` constructor body, remove the `SetupInspectorAccelerator(this);` line (currently line 286). The rest of the constructor stays.
-
-- [ ] **Step 3: Remove redundant `wxInspectable` from `MainFrame`**
-
-In `src/slic3r/GUI/MainFrame.hpp`, line 96, change:
-
-```cpp
-// Before:
-class MainFrame : public DPIFrame, public wxInspector::wxInspectable
-// After:
-class MainFrame : public DPIFrame
-```
-
-`MainFrame` now gets `wxInspectable` through `DPIFrame` → `DPIAware<wxFrame>`.
-
-- [ ] **Step 4: Remove redundant `SetupInspectorAccelerator` from `MainFrame` constructor**
-
-In `src/slic3r/GUI/MainFrame.cpp`, line 304, remove the line:
-
-```cpp
-SetupInspectorAccelerator(this);
-```
-
-It is now called automatically by the `DPIAware<wxFrame>` constructor.
-
-- [ ] **Step 5: Build to verify compilation**
-
-```powershell
-$cmakePath = "D:\VisualStudio\2026\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe"
-& $cmakePath --build . --config RelWithDebInfo --target ALL_BUILD -- -m
-```
-
-Expected: Build succeeds with zero new errors or warnings.
-
-- [ ] **Step 6: Commit**
-
-```bash
-git add src/slic3r/GUI/GUI_Utils.hpp src/slic3r/GUI/MainFrame.hpp src/slic3r/GUI/MainFrame.cpp

-# wxInspector Plugins for OrcaSlicer — 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:** Build two wxInspector plugins (DPIAware + CustomWidgets) that expose OrcaSlicer custom control properties in the inspector's property grid.
-
-**Architecture:** Two plugins in a shared folder under `src/slic3r/Utils/wxInspectorPlugins/`. DPIAwarePlugin uses `dynamic_cast<DPIFrame*>/<DPIDialog*>` for detection; CustomWidgetsPlugin uses per-type `dynamic_cast`. Both registered as static singletons via a single inline function in `Registration.hpp`, called from `MainFrame` constructor.
-
-**Tech Stack:** C++17, wxWidgets, wxInspector plugin API (`wx/inspector/plugin.h`, `wx/inspector/inspector.h`), OrcaSlicer custom widget headers
-
-## Global Constraints

-
-After line 16 (`void SetHalfChecked(bool value = true);`), add:

-
-After line 44 (`void SetCornerRadius(double radius);`), add:
-
-```cpp
-int GetCornerRadius() const { return static_cast<int>(radius); }
-```
-
-(Note: `radius` is inherited from `StaticBox` which has it as a protected `double` member.)
-
-- [ ] **Step 5: Add LabeledStaticBox getter declarations in LabeledStaticBox.hpp**

-
-### Task 5: Wire plugins into MainFrame and CMakeLists
-
-**Files:**
-- Modify: `src/slic3r/GUI/MainFrame.cpp` (add include + registration call)
-- Modify: `src/slic3r/CMakeLists.txt` (add 4 source files)
-
-**Interfaces:**
-- Consumes: Tasks 1-4 (all plugins and registration helper)
-- Produces: Registered plugins available at runtime, buildable project
-
-- [ ] **Step 1: Add include in MainFrame.cpp**
-
-After the existing includes (around line 30, near the other Utils includes), add:
-
-```cpp
-#include "slic3r/Utils/wxInspectorPlugins/Registration.hpp"
-```
-
-- [ ] **Step 2: Add registration call in MainFrame constructor**
-
-After `SetupInspectorAccelerator(this);` (currently line ~303), add:
-
-```cpp
-RegisterOrcaInspectorPlugins();
-```
-
-- [ ] **Step 3: Add source files to CMakeLists.txt**
-
-Find the `SLIC3R_GUI_SOURCES` list in `src/slic3r/CMakeLists.txt`. After the existing `Utils/*.cpp` entries (around line 650-754), add:
-
-```cmake
-Utils/wxInspectorPlugins/DPIAwarePlugin.hpp
-Utils/wxInspectorPlugins/DPIAwarePlugin.cpp
-Utils/wxInspectorPlugins/CustomWidgetsPlugin.hpp
-Utils/wxInspectorPlugins/CustomWidgetsPlugin.cpp
-Utils/wxInspectorPlugins/Registration.hpp
-```
-
-(Note: Add all 5 files — 2 .hpp + 2 .cpp + 1 Registration.hpp. wxWidgets cmake needs headers listed too for the resource system.)
-
-- [ ] **Step 4: Commit**
-
-```bash
-git add src/slic3r/GUI/MainFrame.cpp src/slic3r/CMakeLists.txt
-git commit -m "feat: wire wxInspector plugins into MainFrame and build
-
-- Call RegisterOrcaInspectorPlugins() after SetupInspectorAccelerator
-- Add all plugin source files to SLIC3R_GUI_SOURCES"
-```
-
----
-
-### Task 6: Build and verify
-
-**Files:**
-- None modified (verification only)
-
-- [ ] **Step 1: Configure the build**
-
-```powershell
-$cmakePath = "D:\VisualStudio\2026\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe"
-& $cmakePath --build . --config Debug --target ALL_BUILD -- -m
-```
-
-Expected: Build succeeds with zero errors and zero warnings from our new files.
-
-- [ ] **Step 2: Fix any compilation errors**
-
-If the build fails:
-- Check that `#include` paths resolve (the `slic3r/GUI/…` relative paths use `src/` as the include root — verify this is set up in CMake via `include_directories`)
-- Check that `ButtonStyle` and `ButtonType` enums are visible (they're defined in `Button.hpp`)
-- Check that `StateColor` constructor from `wxColour` is valid (it has `StateColor(wxColour const&)`)
-- Check that `LabeledStaticBox::GetBorderColor()` returns by value (StateColor copy is fine)
-- On macOS: static box margin removal call needs `#ifdef __WXOSX__` guard
-
-- [ ] **Step 3: Launch OrcaSlicer and verify inspector**
-
-Launch the built OrcaSlicer, press Ctrl+Shift+I to open the inspector:
-1. Select the MainFrame in the tree — verify "DPI Scaling" category appears with Scale Factor, Prev Scale Factor, EM Unit, Normal Font, Force Rescale
-2. Select an Orca Button — verify "Orca Button" category appears
-3. Select an Orca CheckBox — verify "Orca CheckBox" category appears
-4. Edit a property value (e.g., Scale Factor) — verify the setter applies correctly
-5. Select a LabeledStaticBox — verify corner radius, border width, border color, scale appear
-
-- [ ] **Step 5: Commit (if fixes were needed) or mark complete**
-
-```bash
-git status
-```
-
-If clean: verification complete. If changes were made: `git add` and commit with fix message.

-# Move `wxInspectable` into `DPIAware` — Design Spec
-
-Date: 2026-07-23
-Branch: `dev/layout-inspector`
-
-## Overview
-
-Move the `wxInspector::wxInspectable` base class from individual leaf classes (`DPIDialog`, `MainFrame`) into the common `DPIAware<P>` template. This makes every DPIAware widget automatically visible in the inspector tree without requiring each subclass to opt in.
-
-## Motivation
-
-Currently, only `DPIDialog` and `MainFrame` explicitly inherit `wxInspectable`. `DPIFrame` (which `MainFrame` inherits from) does not — `MainFrame` adds it manually. This means:
-
-- Any `DPIAware<T>` widget that isn't `DPIDialog` or `MainFrame` is invisible in the inspector tree
-- `DPIFrame` subclasses (`BaseTransparentDPIFrame`, `ImageDPIFrame`, `ModelMallDialog`, `MediaFileFrame`, `SecondaryCheckDialog`, `PrintErrorDialog`, etc.) don't appear
-- Adding a new DPIAware widget type requires remembering to also inherit `wxInspectable`
-
-Moving `wxInspectable` to `DPIAware` fixes this for all current and future DPIAware widgets at once.
-
-## Design
-
-### Change 1: `GUI_Utils.hpp` — `DPIAware<P>`
-
-Add `wxInspector::wxInspectable` as a second base class, and call `SetupInspectorAccelerator(this)` in the constructor (after `this->CenterOnParent()`):
-
-```cpp
-// Before:
-template<class P> class DPIAware : public P
-
-// After:
-template<class P> class DPIAware : public P, public wxInspector::wxInspectable
-```
-
-Add in the constructor body (after `this->CenterOnParent()` at line 110):
-```cpp
-SetupInspectorAccelerator(this);
-```
-
-This gives every `DPIAware<T>` widget both inspectability and the Ctrl+Shift+I keyboard shortcut automatically. `#include <wx/inspector/inspector.h>` is already present in the file.
-
-### Change 2: `GUI_Utils.hpp` — `DPIDialog`
-
-Remove the now-redundant `wxInspector::wxInspectable` and the `SetupInspectorAccelerator(this)` call:
-
-```cpp
-// Before:
-class DPIDialog : public DPIAware<wxDialog>, public wxInspector::wxInspectable
-// ...
-    SetupInspectorAccelerator(this);
-
-// After:
-class DPIDialog : public DPIAware<wxDialog>
-// (SetupInspectorAccelerator call removed — now done in DPIAware constructor)
-```
-
-`DPIDialog` gets `wxInspectable` and the accelerator through `DPIAware<wxDialog>` now.
-
-### Change 3: `MainFrame.hpp` — `MainFrame`
-
-Remove the now-redundant `wxInspector::wxInspectable`:
-
-```cpp
-// Before:
-class MainFrame : public DPIFrame, public wxInspector::wxInspectable
-
-// After:
-class MainFrame : public DPIFrame
-```
-
-`MainFrame` gets `wxInspectable` through `DPIFrame` → `DPIAware<wxFrame>`.
-
-### Change 4: `MainFrame.cpp` — `MainFrame` constructor
-
-Remove the now-redundant `SetupInspectorAccelerator(this)` call (line 304). It will be called automatically by the `DPIAware` constructor.
-
-## Impact
-
-| Widget | Before | After |
-|--------|--------|-------|
-| `DPIDialog` subclasses (~80) | ✓ inspectable | ✓ inspectable (transitive) |
-| `MainFrame` | ✓ inspectable | ✓ inspectable (transitive) |
-| `DPIFrame` subclasses (8 others) | ✗ invisible | ✓ inspectable |
-| Future `DPIAware<T>` | ✗ invisible | ✓ inspectable |
-
-## Files Modified
-
-| File | Change |
-|------|--------|
-| `src/slic3r/GUI/GUI_Utils.hpp` | `DPIAware<P>` gains `wxInspector::wxInspectable` + `SetupInspectorAccelerator(this)` call; `DPIDialog` drops redundant `wxInspector::wxInspectable` and `SetupInspectorAccelerator(this)` |
-| `src/slic3r/GUI/MainFrame.hpp` | `MainFrame` drops redundant `wxInspector::wxInspectable` |
-| `src/slic3r/GUI/MainFrame.cpp` | Remove redundant `SetupInspectorAccelerator(this)` from MainFrame constructor |
-
-## Non-Goals
-
-- The `DPIAwarePlugin` detection logic (`dynamic_cast<DPIFrame*>` / `dynamic_cast<DPIDialog*>`) is unchanged
-- No new DPI properties — this is purely about tree visibility and accelerator setup
-
-## Risk Assessment
-
-- **Multiple inheritance**: `DPIAware<P>` already has a vtable (virtual destructor). Adding `wxInspectable` adds a second base but no additional data members. The `wxInspector::wxInspectable` class is expected to be a lightweight marker interface.
-- **Build**: No new includes needed; `<wx/inspector/inspector.h>` is already included in `GUI_Utils.hpp`.
-- **Cross-platform**: The change is standard C++ multiple inheritance — no platform-specific concerns.

-# wxInspector Plugins for OrcaSlicer Custom Controls — Design Spec
-
-Date: 2026-07-23
-Branch: `dev/layout-inspector`
-
-## Overview
-
-Create wxInspector plugins that expose OrcaSlicer's custom widget properties in the inspector's property grid. Without these plugins, the inspector shows only generic wxWidgets properties — missing all DPI-awareness data, custom styling, and Orca-specific control state.
-
-## Goals
-
-1. **DPIAware properties** — Inspect and update `scale_factor`, `prev_scale_factor`, `em_unit`, and `normal_font` on any DPIAware-derived widget
-2. **Custom widget properties** — Surface Orca-specific properties on `Button`, `CheckBox`, `TextInput`, `SwitchButton`, `ProgressBar`, `Label`, and `LabeledStaticBox`
-3. **Minimal source changes** — Only add trivial (one-line) getters/setters to existing classes; no architectural refactoring of Orca's widget hierarchy
-
-## Non-Goals
-
-- Custom inspector panels or AUI tabs (use the existing property grid and method invoker)
-- Python-plugin integration (this is C++ wxInspector, not Orca's Python plugin system)
-- Event logging customization (the built-in event logger already works)
-
-## Architecture
-
-### Two Plugins
-
-| Plugin | Class | Files |
-|--------|-------|-------|
-| DPIAware plugin | `DPIAwarePlugin` | `DPIAwarePlugin.hpp`, `DPIAwarePlugin.cpp` |
-| Custom widgets plugin | `CustomWidgetsPlugin` | `CustomWidgetsPlugin.hpp`, `CustomWidgetsPlugin.cpp` |
-| Registration helper | inline function | `Registration.hpp` |
-
-All files live under `src/slic3r/Utils/wxInspectorPlugins/`.
-
-### Plugin Detection Strategy
-
-**DPIAware plugin**: Uses `dynamic_cast<DPIFrame*>` and `dynamic_cast<DPIDialog*>` as detection gates. `DPIFrame` = `DPIAware<wxFrame>`, `DPIDialog` = `DPIAware<wxDialog>`. Since these are concrete typedefs, `dynamic_cast` works at runtime. This covers `MainFrame`, `SettingsDialog`, and all 8 calibration dialogs (which inherit `DPIDialog`).
-
-**Custom widgets plugin**: Gates broadly on `CLASSINFO(wxWindow)`, then uses per-type `dynamic_cast` inside `GetProperties` to check each Orca-specific type. Only matching types append properties.
-
-### Registration
-
-A single `RegisterOrcaInspectorPlugins()` inline function in `Registration.hpp` creates both plugins as function-local statics (matching the wxInspector built-in provider pattern) and registers them via `wxInspector::RegisterPlugin()`.
-
-Called once from `MainFrame::MainFrame()` after `SetupInspectorAccelerator(this)`.
-
-### Why Separate Plugins?
-
-- DPIAware is a C++ template concept (not a wxClassInfo-isKindOf check), so it needs its own detection logic
-- Custom widgets use standard wxClassInfo-based detection, matching the built-in provider pattern
-- Two focused files are easier to review and maintain than one monolithic plugin
-- Compile-time failure isolation: if a widget header changes, only one plugin breaks
-
-## DPIAware Plugin — Property Specification
-
-### Source Changes (GUI_Utils.hpp)
-
-Four one-liner methods added to the `DPIAware<P>` template class (public section):
-
-```cpp
-float scale_factor() const       { return m_scale_factor; }  // already exists
-float prev_scale_factor() const  { return m_prev_scale_factor; }  // already exists
-int   em_unit() const            { return m_em_unit; }  // already exists
-void  set_scale_factor(float v)      { m_scale_factor = v; }      // NEW
-void  set_prev_scale_factor(float v) { m_prev_scale_factor = v; } // NEW
-void  set_em_unit(int v)             { m_em_unit = v; }           // NEW
-bool  force_rescale() const          { return m_force_rescale; }  // NEW
-// m_normal_font getter already exists: normal_font()
-```
-
-### Detection
-
-```cpp
-bool CanProvideProperties(wxClassInfo* info) override {
-    // Gated in GetProperties via dynamic_cast on the window itself
-    return info->IsKindOf(CLASSINFO(wxWindow));
-}
-```
-
-In `GetProperties`:
-```cpp
-auto* win = obj.AsWindow();
-bool isDPI = dynamic_cast<DPIFrame*>(win) || dynamic_cast<DPIDialog*>(win);
-if (!isDPI) return props;
-```
-
-### Property Table (category: "DPI Scaling")
-
-| Name | Type | Editable | Getter | Setter |
-|------|------|----------|--------|--------|
-| Scale Factor | String (float) | Yes | `dpi->scale_factor()` | `dpi->set_scale_factor(v)` |
-| Prev Scale Factor | String (float) | Yes | `dpi->prev_scale_factor()` | `dpi->set_prev_scale_factor(v)` |
-| EM Unit | Integer | Yes | `dpi->em_unit()` | `dpi->set_em_unit(v)` |
-| Normal Font | ReadOnly | No | `dpi->normal_font().GetNativeFontInfoDesc()` | — |
-| Force Rescale | Boolean (ReadOnly) | No | `dpi->force_rescale()` | — |
-
-**Note on setters**: The setters simply store values. They do NOT trigger a widget rescale/layout. To see the effect of a changed scale factor, use the inspector's Methods panel to call `Layout()` or resize the window — which triggers the DPI_CHANGED event path naturally.
-
-## Custom Widgets Plugin — Property Specification
-
-All properties are appended to the built-in wxWindow properties. Each widget type is independently detected via `dynamic_cast`.
-
-### Detection gates (in `GetProperties`)
-
-```cpp
-auto* win = obj.AsWindow();
-if (auto* btn = dynamic_cast<Button*>(win))          { addButtonProperties(btn, props); }
-if (auto* cb  = dynamic_cast<CheckBox*>(win))         { addCheckBoxProperties(cb, props); }
-if (auto* ti  = dynamic_cast<TextInput*>(win))        { addTextInputProperties(ti, props); }
-if (auto* sb  = dynamic_cast<SwitchButton*>(win))     { addSwitchButtonProperties(sb, props); }
-if (auto* pb  = dynamic_cast<ProgressBar*>(win))      { addProgressBarProperties(pb, props); }
-if (auto* lbl = dynamic_cast<Label*>(win))            { addLabelProperties(lbl, props); }
-if (auto* lsb = dynamic_cast<LabeledStaticBox*>(win)) { addLabeledStaticBoxProperties(lsb, props); }
-```

-
-## Build & Linking
-
-The `wxInspector` dependency is already wired:
-- `deps/wxInspector/wxInspector.cmake` fetches and builds wxInspector
-- `src/CMakeLists.txt` lines 92-93 link `wxInspector::wxInspector` into `wxWidgets_LIBRARIES`
-- The plugin files only need `#include <wx/inspector/plugin.h>` and `#include <wx/inspector/inspector.h>` — both available from the installed dependency
-
-No new CMake dependencies needed. Only the new source files need listing in `SLIC3R_GUI_SOURCES`.
-
-## Error Handling & Edge Cases
-
-- **Stale pointers**: Plugin lambdas capture raw pointers, regenerated on every `GetProperties` call (matching wxInspector's built-in provider pattern). Pointers live only until the next tree selection.
-- **Widget destruction**: If a widget is destroyed while the inspector is showing its properties, `InspectableObject::IsValid()` returns false and properties are not displayed. The inspector won't show stale data.
-- **Invalid property values**: Setters use `sscanf` / `ToLong` with validation (matching built-in patterns). Bogus input is rejected — setter returns `false`, property grid shows error state.
-- **DPI drift**: Setting `scale_factor` without triggering rescale means displayed sizes don't match the new factor. This is acceptable — the inspector is a developer tool; operators know to call `Layout()` after making changes.
-- **Missing widget type**: If a `dynamic_cast` fails for all types, only built-in wxWindow properties are shown. No crash, no error — just reduced info.
-
-## Future Work (Out of Scope)
-
-- **StateColor visualization**: `StateColor` is a multi-value type (maps bitmask states to colors). A full solution would need a custom property editor (e.g., a table showing each state→color pair). Keep it simple for now.
-- **ScalableBitmap display**: Could show the bitmap as an inline thumbnail. Complex property editor work — deferred.
-- **More widget types**: `SwitchBoard`, `MultiSwitchButton`, `StepCtrl`, `FanControl`, `DropDown`, `ComboBox`, `AMS*` widgets could all benefit. Add as needed.
-- **Property refresh on tree selection**: Currently properties are static snapshots. A "refresh" button or auto-poll could keep values current for rapidly-changing widgets (progress bars, etc.). The built-in wxInspector already provides a tree-refresh button.

+// Fast, geometry-free preview of texture displacement: perturbs the *shading* normal from the
+// height texture's local gradient (a bump map), faded out by the per-vertex paint weight. The
+// true, exact result is what "Bake" produces via libslic3r/TextureDisplacement.cpp on the CPU.
+//
+// The bake displaces each surface point along its normal by H = +/- depth_mm * (h(uv) - midlevel),
+// with uv from the layer's projection. The perturbed normal is the analytic
+//
+//     N' = normalize(N - (dH/da) * T - (dH/db) * B)
+//
+// over any orthonormal surface tangent pair (T, B), where the two slopes are real mm-per-mm
+// derivatives. Two things have to be right for the preview's apparent depth to match the bake's:
+// the tangent frame the gradient is expressed in, and the uv->mm scale that turns a texel
+// difference into a slope. Getting the scale wrong is a uniform flattening (a raw texel difference
+// is dh over one texel step, not over one mm); getting the frame wrong tilts the bump along the
+// wrong axes.
+//
+// Two projection paths:
+//   * Triplanar (use_vertex_uv = 0): uv and the tangent axes are derived in-shader from the dominant
+//     normal axis, mirroring libslic3r's project_planar()/apply_uv_transform(), and the slope is
+//     formed analytically (there is a closed-form uv, so 1 uv unit is exactly tiling_scale mm).
+//   * Precomputed uv (use_vertex_uv = 1, used for LSCM): uv comes per-vertex from the CPU (the LSCM

-"""Twistify -- twist/taper/wobble any model at slice time.
-
-At Step.posSlice, every layer's sliced surfaces are transformed by a similarity
-about the object's bounding-box center as a function of Z -- edited IN PLACE
-through the host geometry classes (ExPolygon.rotate/scale/translate). Each
-surface is rotated about the center, then (if tapering) translated to the
-origin, uniformly scaled, and translated back, so the taper stays centered on
-the object instead of drifting toward the coordinate origin. An optional X
-wobble is applied last. After the per-region edits, layer.make_slices()
-re-derives the layer's merged islands so overhang/bridge/skirt/support stay
-coherent. The split slice loop runs make_perimeters() right after the hook, so
-the transform cascades into perimeters, infill, and the final G-code -- the
-preview corkscrews and the print keeps correct walls/infill/flow.
-
-Because we edit geometry in place, surface types are preserved automatically
-(no per-surface type carry needed), and no numpy is required --
-rotate/scale/translate are host methods. Parameters come from self.get_config()
-(see _params below); the host seeds them from get_default_config() the first
-time the plugin loads. The first object layer is untouched (z_rel = 0), so bed
-adhesion is unaffected.
-
-The plugin also ships its own configuration UI (has_config_ui/get_config_ui):
-a self-contained page the Plugins dialog renders instead of the JSON editor,
-drawing the transform it is about to apply as an isometric stack of layer
-outlines. It reaches the host only through the injected window.orca bridge --
-getConfig/saveConfig/restoreDefaults/getContext/onConfig/onTheme -- and styles
-itself from the --orca-* theme variables the host hands the frame, so it
-follows OrcaSlicer's light/dark theme.
