fix: Python thread audit shim kwargs forwarding

update_material_item_pos() chose the left or right nozzle panel from the printer alone and then read m_filaments_map, which reset_and_sync_ams_list() fills only for a multi-nozzle plate. Clicking Print plate with a plate sliced for one nozzle (A1) and a two-extruder printer selected (X2D) read the empty map and crashed. For a single-nozzle plate the dialog now uses the single panel.

+  hardware DMABUF renderer, leaving web views blank or slow; FORCE_SHM keeps accelerated compositing and only
+  skips the hardware path, while disabling compositing drops it. Threaded scrolling is a separate,
+  release-dependent default (off in 2.44/2.45, on from 2.46). `WEBKIT_DISABLE_DMABUF_RENDERER` is not a
+  substitute — it is read first, leaves the transport set empty (no compositing from 2.44 on, where the
+  X11/Wayland fallback renderers were removed) and has a reported crash path. On Debian/Ubuntu and
+  openSUSE the `isNVIDIA()` patch returns before the FORCE_SHM check, so `WEBKIT_FORCE_DMABUF_RENDERER=1`
+  must clear it first; that variable exists only in those patches. WebKit reads all of these once per
+  process, before the first WebView.
+  The test is `/proc/driver/nvidia/version`, so a hybrid laptop that renders on its iGPU also takes the
+  shared-memory path, which is a per-frame GPU readback rather than zero-copy; exporting
+  `WEBKIT_DMABUF_RENDERER_FORCE_SHM=0` in the environment restores the hardware path.

+# Color picker
+
+The color picker is a local HTML dialog hosted by `ColorPickerDialog`, a
+`WebViewHostDialog` subclass. Its header and implementation own the ordered
+selection contract and shared filament conversion. Bridge validation, favorites
+persistence, placement and gettext strings remain private to the implementation.
+Its colors use the existing `ColorRGBA` utility.
+It uses a native title bar and fixed window border, allowing dragging but no
+manual resizing or maximization. Native title-bar colors use the application's
+shared dialog dark-theme update on creation and theme changes.
+Like SpeedDial, the host disables browser zoom accelerators, restores native
+WebView focus on activation and readiness, and synchronizes layout and the macOS
+viewport before repainting the backend. Activation never dismisses this modal
+dialog; focus restoration preserves an active editor and its partial input.
+The initialized page reports
+its intrinsic content height; native code validates the current page identifier
+and bounded numeric height, converts CSS pixels to device-independent window
+size, and fits within the display's work area. Identical sizes are ignored. The
+page observes content rather than viewport height, so resizing does not create
+a feedback loop; oversized content remains scrollable.
+The panel snapshots the triggering color or More Colors button's screen rectangle.
+It aligns below the button, flips above when needed, and clamps to that button's
+display work area on initial display. Later content and DPI changes update only
+the client size, preserving the position chosen by dragging the title bar.
+wxGTK clears the dialog's default
+parent-centering constraint and reapplies its native position after showing,
+bypassing wxGTK's requested-position cache. Absolute top-level placement remains
+subject to the window manager; Wayland compositors control it. The official filament palette's
+existing placement is independent of this custom panel.
+A solid selection contains one color; a gradient contains exactly two ordered
+endpoints. The bridge represents these as `{"type":"solid|gradient",
+"colors":["#RRGGBBAA", ...]}`. RGB input is also accepted and becomes opaque.
+Native validation rejects malformed hex and incorrect cardinality.
+
+The project filament color action and the official filament picker's More Colors
+action enable two-endpoint gradients and independent endpoint alpha. The preset
+combo box reads project colors in their stored vector order locally and applies
+changes through `sync_colour_config`,
+retaining the existing RGB/RGBA profile/project formats and dirty marking.
+Sidebar gradient and segmented multicolor swatches draw colors in the supplied
+order without sorting them.
+Opaque colors use `#RRGGBB`; nonopaque colors use `#RRGGBBAA`, including fully
+transparent alpha `00`. Initial selections, alpha-only edits and cancellation
+retain stored alpha. Ordered
+custom results bypass the official palette's `FilamentColor` set. Choosing an
+official swatch retains its existing palette behavior.
+The Linux sidebar's Change extruder color menu uses this same custom editor and
+the filament swatch anchor, including alpha, ordered gradients and configuration syncing.
+
+Striped colors and gradients with more than two endpoints cannot be represented
+by this editor. A notice explains that the current selection is retained; the
+editor starts from the first color, and unchanged confirmation is a no-op.
+Cancellation is also a no-op. If the WebView backend cannot initialize, a local
+unavailable panel offers Cancel and Escape, without opening a system color picker.
+
+Generic color option fields use an ordinary color button on every platform and
+open the same panel with gradients and alpha disabled. The panel is anchored to
+the field button. Empty or invalid field values remain undefined (the empty
+string), distinct from opaque black. Right-click resets to undefined. Cancel does
+not notify the field; confirmation and reset notify only when its RGB string
+changes. Programmatic assignments remain silent, and reading a field never
+writes legacy favorites.
+
+AMS material settings retain their fixed/AMS swatches and first-level popup. Only
+its custom-color action opens the solid, opaque editor, anchored to that custom
+control. The transient popup releases its grab while the modal is open and returns
+to the same selection on cancellation. Confirmation uses the existing default-color
+and packed RGBA event path. Device permission/status checks remain at the first-level
+entry.
+
+Texture import's color-mapping Add Material action opens a solid, opaque editor
+anchored to the mapping row. The existing filament limit is checked before opening.
+The first-level material popup closes as an action; its callback is copied before
+dismissal, so popup destruction does not invalidate the modal's completion path.
+Confirmation invokes the existing virtual-filament callback once; cancellation
+adds no material.
+
+Native gettext strings are installed at document start. Static page labels and
+palette names use stable English keys; RAL codes, channel symbols, and numeric
+labels remain data. The palette color values do not depend on the UI language.
+The application locale also sets the document language. Numeric editor validation
+uses the application's gettext messages, rather than browser language defaults;
+missing translations fall back to the stable English keys.
+
+The pure color/state regressions run with
+`node --test resources/web/dialog/ColorPickerDialog/colorpicker.test.js`.
+Optional real-browser regressions live beside them in
+`colorpicker.browser.test.js`. They use an existing Playwright installation
+(`ORCA_PLAYWRIGHT_MODULE` can name its module path) and an installed browser
+(`ORCA_BROWSER_EXECUTABLE` can name its executable), without adding a production
+dependency. They cover bridge initialization, capability combinations, invalid
+editor recovery, ordered endpoint alpha, favorites, gettext keys, and live theme
+changes. These browser checks complement native contract/persistence tests; they
+do not establish the full native modal confirmation and favorites journey.
+
+Gradient and alpha capabilities are independent and default off. Unsupported
+gradients are rejected; disabled alpha normalizes the selected result to opaque.
+Favorites retain both capabilities independently of the current caller. The page
+stores alpha as a byte and only converts to percentage when displaying or editing
+opacity, so switching endpoints does not change alpha precision.
+
+The page starts disabled. Each document supplies a page identifier in its ready
+message, receives native initialization, and acknowledges it before native code
+accepts confirmation or favorite updates. Repeated initialization does not reset
+edits, and messages from an obsolete document are ignored. Native WebView message
+handling is deferred and guarded by a lifetime token. Only a validated confirmation
+sets the optional result. Cancel, Escape and native window close leave it empty.
+
+Favorites belong to application configuration, separately from the selected result,
+in the editor configuration returned by `AppConfig::config_path()` under `data_dir()`.
+The `color_picker` section has string `version` equal to `1` and a `favorites`
+string containing a JSON array of typed selections. Native helpers normalize and
+deduplicate this array in order and limit it to 24 entries. Updates replace the
+entire section and immediately call `AppConfig::save()`, so accepted favorite
+changes survive cancellation. Empty arrays are saved explicitly. Core `AppConfig`
+only stores the raw section; color validation belongs to the GUI boundary.
+
+When the section is absent, valid solid colors from `custom_color_list` are imported
+once, without changing that legacy section. The legacy native picker saves decimal
+`r,g,b,a` byte strings; hexadecimal RGB and RGBA strings are also supported. Migration
+strictly validates all four decimal channels and preserves alpha. Gradient strings
+and malformed values are ignored. The new version and an empty array are
+saved even when there is nothing to import. A present section with an unknown or
+missing version is left untouched and disables favorite writes. Malformed version

+# Travel optimization — High Level Design
+
+## Purpose and scope
+
+Inside an island, the infill paths of each region are chained into one print
+order by a greedy pass that joins the closest free path ends first. That pass
+leaves its longest joins for last, and they often cross the whole island. Two
+things shorten the travel between infill paths:
+
+- the fill generators join their lines into as few paths as they can, since
+  every separate path needs a travel to it;
+- the G-code export refines the greedy chain with a local search that shortens
+  the straight-line travel between the paths.
+
+The refinement covers every chain that `chain_and_reorder_extrusion_entities()`
+builds from a start point: the infill and ironing of `GCode::extrude_infill()`
+and the support of `GCode::extrude_support()`, as well as the order of objects
+and islands under `print_order` Default. It changes only the order and the
+direction of the paths, not the paths or the walls. Neither part has a setting.
+
+## The chain
+
+`ObjectByExtruder::Island::Region::append()` flattens every sortable fill
+collection into its paths, so the paths of all the fills of a region in one
+island are chained together. A collection that must keep its order (`no_sort`:
+monotonic, concentric, a forced fill order, the flow calibration) stays a single
+entry that cannot be reversed. Paths that must keep their direction cannot be
+reversed either: Grid's, since it alternates their direction between layers for
+strength, and those of a fill with a forced order. A loop starts and ends at the
+same point, so reversing it changes nothing.
+
+`extrude_infill()` chains each region from the current nozzle position with
+`chain_and_reorder_extrusion_entities()`, and chains the paths inside a nested
+sortable collection the same way; `extrude_support()` chains the support paths
+of a layer so too, unless they keep their order. The overload without a start
+point, used to chain collections while slicing, keeps the greedy chain. The
+order the fill generators give their paths does not reach the G-code for a
+sortable fill, which is chained again.
+
+## Connecting the lines
+
+Most patterns cut their lines at the infill boundary, and `Fill::connect_infill()`
+joins pairs of line ends that are neighbors on a boundary contour by the arc of
+wall between them, shortest arcs first, as long as neither end is joined yet and
+the join closes no loop. An arc is joined when it is shorter than
+`infill_anchor_max`, or than two anchors and a line width if that is longer:
+two ends further apart each get an anchor toward the other, and where those
+would meet, the join prints about as much wall as one path instead of two.
+
+Regular patterns leave many arcs of the same length, and the order among them
+decides the pairing. In an arbitrary order the pairs along one wall can fall out
+of step, such as lines 1–2 and 3–4, then 6–7 and 8–9, which leaves the end of
+line 5 loose, and every loose end starts or ends a separate path. So the arcs
+are also sorted in steps of half the line spacing and, within a step, along each
+contour forwards and backwards, which pairs the ends of a wall in one phase.
+Each order is replayed on the flags and a union-find of the lines, without
+building any path, and the one that joins the most lines is used; a tie keeps
+the shortest-first order.
+
+The replay includes the last pass, which joins any two open ends that are
+neighbors on a contour. With multiline infill the main pass leaves the copies of
+one line to that pass, so that each copy reaches a wall of its own. Two
+neighboring groups cut at both walls can then be joined at either wall by arcs
+of the same length: at one, their open ends stay next to their own copies, which
+the last pass joins, so each line prints out and back; at the other, the copies
+end up in separate paths printed apart.
+
+A line end left unpaired gets an anchor, a piece of the wall at most
+`infill_anchor` long. It runs toward the nearest open end of another path,
+looking up to 64 ends along the contour, since the next path usually starts
+there; without one it takes the side with more free wall. With multiline infill
+an anchor toward a copy of the same line stops short of the copy rather than
+printing over it. A copy is a neighboring end less than the group width
+(`multiline` spacings) across the line, at any wall angle, while the next group
+lies a whole line spacing away. Meeting the wall at an angle θ, the copy covers
+half a width over sin θ of the wall on each side of its end, so the anchor stops
+that far and half its own width before it, or is left out; the end still counts
+as anchored, so the last pass pairs the other ends as before.
+
+Last, `Fill::fill_surface_extrusion()` joins the sparse infill lines whose ends
+are at most two line spacings apart with a straight piece. With the anchors off
+(`infill_anchor_max` 0) nothing above runs and this is the only joining; with
+them on, it takes what the steps above leave next to each other, such as two
+anchors that stop just short of each other or a short piece cut off by a corner.
+A gap that short leaves no room to print anything in between, and as a travel it
+is the one hop a reordering can trade for a longer travel that retracts.
+Multiline copies leave the most such ends: one spacing apart across the line,
+their ends where it meets a wall at an angle θ are one spacing over sin θ apart
+along it, so two spacings reach walls met at 30° and steeper.
+
+Ends that meet are joined first, then the gaps between the leading ends of their
+lines, along each line's overall direction, then the rest, shortest first within
+each, without closing a loop or crossing a line or another join. Taking the
+leading ends first joins every pair of copies at the same side, which leaves
+their open ends next to each other; by length alone, neighboring pairs were
+joined at different walls and the travel between them crossed the island. Lines
+that cannot reverse, such as Grid's, only join the end of one to the start of the
+next, and fills that keep their order are left alone.
+
+## The search
+
+A chain of up to eight paths is found exactly, by dynamic programming over the
+subsets of paths: a state is the paths visited so far, the last one and its
+direction, about four thousand states for eight paths. The shared greedy
+chaining, `chain_segments_greedy_constrained_reversals_()`, does the same for two
+to four segments, which also orders up to four islands of a layer and the loops
+of a perimeter collection exactly. Either way the first path is no longer
+always the one nearest the start; with a free end, a path near the start can be
+worth leaving for last.
+
+Objects (`print_order` Default) and the tour of islands across objects are
+visited in the same order on every layer, so `chain_points_with_postprocessing()`
+orders them as a closed tour rather than an open chain. Up to ten points the
+shortest tour is found exactly by the same dynamic programming with the first
+point fixed; with a start point the tour then begins at the point nearest it.
+Larger sets take the greedy chain and alternate 2-opt, or-opt and crossing
+removal; or-opt moves runs of up to three points next to one of the eight points
+nearest an end of the run, found on the same grid as the chain's candidates.
+
+For longer chains, the search refines the greedy chain. On an island cut into many short pieces,
+such as infill without anchors, that chain can sweep away from the nozzle and
+come back for the rest with one long jump, which no local move below removes.
+So a nearest-next chain, going from the nozzle to the nearest free path end each
+time, is built too; when it is already shorter than the refined greedy chain, it
+is refined and used instead. Elsewhere it costs one grid query per path.
+
+`improve_chain_by_local_search()` sees the chain as a sequence of segments with
+an entry and an exit point each. Its cost is the straight distance from the
+nozzle to the first entry plus the distance from every exit to the next entry;
+the end of the chain is free. It applies three kinds of moves:
+
+- 2-opt reverses a run of segments, which flips each of them and replaces the
+  two links at the ends of the run.
+- Or-opt moves a run of up to three segments between two others, flipped or
+  not.
+- A run of any length that starts or ends next to the nozzle moves to the front.
+  Local search can settle on a chain that starts with a block of paths far from
+  the nozzle while the paths next to it sit in the middle, and moving that block
+  takes more than three segments at once.
+
+A move that would flip a segment that cannot be reversed is skipped, so such
+segments are only reordered.
+
+A move is tried only if every link it creates joins an end point to one of the
+32 end points nearest to it, which covers every move on a chain of up to 17
+segments, as most islands are; with 8 candidates the search missed most of the
+gain on grid-like patterns such as Triangles. The candidates come from a uniform
+grid of about two end points per cell, searched in rings of cells around the
+query. `KDTreeIndirect` visits its subtrees in a fixed order rather than the
+nearer one first, so a query for 32 points walks most of the tree, and on long
+chains finding the candidates would cost more than the search itself.
+
+The candidates of an end point are tried nearest first, and only while they are
+closer to it than the link the move would replace there. A 2-opt move that pays
+off creates a link shorter than the one it replaces at one of its two ends, so
+this misses no 2-opt move. An or-opt move is tried only while its new link is
+shorter than what taking the run out saves, which skips a few or-opt moves that
+would still pay off but cuts the search on long chains to a fraction.
+
+The search works through a queue of segments and applies the first move that
+shortens the chain around the segment it examines. After a move, only the
+segments next to a changed link are queued again. A new link can also make room
+for a run elsewhere that no segment next to it would try, so when the queue
+empties after any move, every segment is queued once more, and the search ends
+when such a sweep finds no move.
+
+Every move shortens the chain by more than `SCALED_EPSILON`, so the result is
+never longer than the greedy or the nearest-next chain and the search ends; a
+cap of 50 moves per segment only bounds its time. The search has no randomness
+and visits the segments in a fixed order, so the same input always gives the
+same G-code.
+
+## Cost
+
+Finding the candidates of an end point visits a few cells, and the nearest-next
+chain makes one such query per path, which only grows where the paths around the
+nozzle are used up and the chain jumps. Examining a segment tries at most a few
+hundred candidate links, usually only the nearest few, plus a scan of the chain
+for the move to the front when it is the first segment, and a move rewrites only
+the range of the chain it changes, so the search stays close to linear in the
+number of segments. Most islands hold a few to a few dozen paths; the cost shows
+on infill cut into thousands of pieces per island, such as dense infill with the
+anchors off. The straight joins only look at the line segments near a candidate
+join for crossings.
+
+## Limitations
+
+The search minimizes straight-line distance. It does not know which travels
+leave the infill area and retract under `reduce_infill_retraction`, nor the
+detours of `reduce_crossing_wall`, and a travel's time is not proportional to
+its length: a short travel is bound by acceleration, so its time grows about
+with the square root of its length. A chain that is shorter in total but trades
+very short travels for longer ones, or for ones past `retraction_minimum_travel`,
+can occasionally take a little longer to print.
+
+The end of the chain is free: it is not steered toward the next island or the
+start of the next layer. The regions of an island are chained one after the
+other, in region order, each from where the previous one ended.
