Dion Moult 094575fc19 ifcviewer-web: async object pick → click-to-select on web
Desktop pick reads the pick staging buffer back with a blocking
`while(!done) waitTickInstance()` spin. On web that spin is a no-op
(Asyncify is off) and hangs the JS event loop, so click-to-select was
dead on web. This adds an async sibling that uses the spontaneous
map-callback pattern (AllowSpontaneous + the browser microtask loop)
already proven by the HiZ readback — no blocking.

  - encodePickReadbackToStaging(x,y,want_normal): the pick-pass render +
    copy-texel-to-staging, extracted from pickObjectAt verbatim and shared
    by both readbacks (desktop sync path unchanged).
  - pickObjectAtAsync(x,y,cb) [web]: encode, then map the staging buffer
    with a spontaneous callback that delivers object_id to cb. One pick in
    flight at a time (a pick issued mid-map is dropped → cb(0)).
  - applyPickToSelection(id, add, remove): routes a pick result through the
    selection state machine (replace / Shift-add / Ctrl-remove / empty-click
    clear), mirroring the desktop ViewportWindow click semantics. selection_
    marks dirty so the next render's uploadSelectionFlagsIfDirty flushes the
    highlight.

main_web wires it: a left release under a 4px drag threshold (no orbit) is
a pick at down-position * devicePixelRatio, with Shift/Ctrl modifiers;
the result callback applies selection and requests a frame. Web + desktop
build clean; 107/107 unit tests pass.

Gorgious56 a757641b84 Bonsai: derive prefs PropertyGroups from EDIT_TYPES
Collapse two parallel hand-maintained lists in the addon-preferences
PropertyGroups into derivations from `tool.Parametric.EDIT_TYPES`:

- GizmoPreferences: the 10 `<name>: BoolProperty` annotations now
  generated from the full EDIT_TYPES list.

- DefaultParameters: add `has_default_parameters` flag to
  ParametricObject (set True on door/window/stair/railing/roof);
  derive the 5 `<name>: PointerProperty(type=BIM<X>Properties)`
  annotations and collapse the 5 hand-written `draw_expandable_panel`
  blocks in `draw_default_parameters` into loops driven by the flag.

Existing `test_gizmo_preferences_field_per_registry_entry` pinned the
GizmoPreferences contract; new
`test_default_parameters_field_per_registry_entry_with_defaults`
pins the DefaultParameters contract (one-directional: flag=True
implies field present, flag=False allows absence).

Gorgious56 82dd1d94de Bonsai: batch host recuts in array/opening paths
Refs gh#8088. Array regen + multi-opening drops fan out N+1 wall recuts
per operator (one per child filling deletion + the final mirror recut),
making CSG opening-subtraction O(N^2) for a linear UX action.

Introduces tool.Geometry.batch_host_recut() — a context manager that
coalesces switch_representation and bpy.ops.bim.update_representation
calls per voided element within one operator transaction. The drain
re-reads the active representation so the recut reflects current IFC.

Wraps 7 entry points (regenerate_array, RegenerateArray, RemoveArray,
AddOpening, RecalculateFill, CloneOpening, regenerate_from_type) and
rewires 7 leaf call sites in opening.py, void/operator.py, and
mirror_parent_void_fillings_to_children.

An AST forward-compat guard pins the rewire contract: no direct
switch_representation or bpy.ops.bim.update_representation in the
three target files outside the helper definitions.

A 16-child array regen now recuts the wall once instead of 17 times.
The CSG cost per recut is unchanged; only the count is reduced.

21 new tests across three lanes (helper unit, entry-point coalescing,
AST guard) — all green.

Gorgious56 4004344c20 Bonsai: TAB enters wall parametric edit
Mirror the icon-click entry into wall parametric edit on the TAB key.
The dispatch in Modifier.try_applying_edit_mode had no branch for fresh
LAYER2 walls, so TAB landed in item mode instead of the parametric
draft + gizmos. Add the missing entry leg of the toggle, placed after
the generic is_object_editing branch so the finish leg still fires
when a wall is already in edit mode.

Dion Moult e70c58fe99 ifcviewer-web: smoke-test the Blob.slice byte-range load path
Adds a second Playwright case that picks the sample sidecar through the
file input, waits for the C side to confirm the blob load (console),
then asserts an orbit drag changes the canvas with zero WebGPU errors.
This exercises the #88 path distinctly from the embedded MEMFS sample —
a broken metadata-head/tail or chunk range read renders blank and fails
the orbit-changed-canvas check. Both cases pass.

Dion Moult 584504dcdc ifcviewer-web: stream user sidecars via Blob.slice byte ranges (#88)
Picked files are no longer copied whole into the wasm heap. The browser
File object stays in JS (Module.__ifcvFile) and is read lazily through
Blob.slice byte ranges, so a 200-500 MB sidecar never enters wasm linear
memory — only chunk-sized slices do.

Mechanism (web-only, #if __EMSCRIPTEN__):

  - JS glue (EM_JS): ifcvFileSize + ifcvReadRangeInto — slice [off,off+n)
    of the File and copy it into a caller-provided heap pointer, then call
    back _ifcv_on_range_done. No malloc across the boundary; C pre-sizes
    the destination from the read plan.
  - webReadRangesAsync: reuses planSidecarReadRanges to coalesce a range
    set into Blob.slice reads (1 MB gap — each slice is an async hop),
    scatters them into a destination laid out in input order, and fires a
    continuation when the whole set lands. An in-flight map keyed by id
    survives unordered_map rehash (scratch buffers are heap-owned).
  - loadSidecarFromBlobWeb: async metadata load — head (16 B) -> index
    count -> tail-to-EOF -> parseSidecarHead/Tail -> applyCachedModel, then
    tags the model streaming_from_blob and frames it.
  - driveStreamingLoads: blob-sourced models route to beginWebChunkLoad
    (async vertex+index range reads -> applyStreamedChunk in the callback),
    holding is_loading until the bytes arrive. The embedded MEMFS sample
    keeps the synchronous fopen path.

shell.html stashes the File and calls _load_sidecar_from_blob_c instead of
FS.writeFile'ing the whole thing; EXPORTED_RUNTIME_METHODS=['FS'] dropped.
Desktop is untouched (the new members + driveStreamingLoads branch are all
emscripten-guarded). Web links clean; desktop rebuilds; 107/107 unit tests
pass.

Dion Moult a0ba3c0b98 ifcviewer: extract pure buffer-based sidecar parse + read-plan helpers
Splits the v13 metadata wire-format knowledge out of the FILE*-bound
streaming reader into pure, buffer-based functions so the web byte-range
path (#88) can reuse it without loading the whole sidecar into the wasm
heap:

  - parseSidecarHead  — validates the 16-byte head, yields num_vertex_bytes
  - parseSidecarTail  — parses meshes/instances/georef/elements/strings
                        from an in-memory tail buffer, bounds-checked
  - planSidecarReadRanges + SidecarReadPlan — the range-coalescing /
    scatter planner, promoted out of the anonymous namespace

readSidecarMetadataOnly and the range readers now call these; desktop
behaviour is unchanged (head + tail are small, the bulk is still skipped
via seek). The metadata tail is split from the head around the bulk
sections, so a blob-backed loader just slices those two regions and
hands the bytes to the same parsers.

Closes a coverage gap: StreamingLoader had no unit tests. Adds
test_streaming_loader.cpp (7 cases: metadata round-trip, corrupt/truncated
rejection, vertex+index range scatter, head validation, tail truncation,
read-plan coalescing). 107/107 unit tests pass.

Dion Moult fcf3a645db ifcviewer-web: add a headless-browser smoke test
Drives the built web page in a real Chrome (channel:'chrome', so no
`playwright install`): waits for wgpu init, then asserts an orbit drag
changes the composited canvas — one check that simultaneously proves the
scene rendered, mouse input is wired, and the log overlay isn't eating
events — and that zero uncaptured WebGPU errors were logged. Every web
bring-up bug so far (blank render, error-buffer cascade, overlay
swallowing input) is this shape; this would have caught them.

serve.mjs statically serves build-web; the config launches headed
against the real GPU (--use-angle=vulkan + --ignore-gpu-blocklist are
load-bearing for a non-null adapter on Linux Chrome). node_modules and
results are gitignored. See README.md to run.

Dion Moult 89beee6514 ifcviewer: detect web pool-grow OOM via provisional sub-buffers
On web we skip the desktop error-scope spin-wait (it blocks the JS event
loop and hangs the page). The old web addSubBuffer then judged success by
`buf != nullptr` — but Dawn-web returns a NON-NULL error buffer on OOM,
so the pool committed an invalid sub-buffer, alloc handed out slices in
it, and every chunk_bind_group built against it failed ("BindGroup is
invalid" spam + a wgpuQueueSubmit panic). Loading a model larger than the
browser's WebGPU budget triggered exactly this.

Add the grown sub-buffer as *provisional* (alloc and the capacity/free
tallies skip it) and validate it through a non-blocking AllowSpontaneous
PopErrorScope. resolveProvisionalGrowth() clears the flag when it's good,
or drops the sub-buffer and latches growth_disabled_ on a real OOM — at
which point the streaming evictor bounds the working set to what fits
instead of cascading. Only one provisional grow is in flight at a time
(growth_pending_). Desktop keeps its synchronous halve-retry path
unchanged. All 100 unit tests still pass.

Dion Moult 2237b4acdd ifcviewer-web: stop the log overlay from covering + blocking the canvas
The status overlay was position:fixed top/left/right with max-height
80vh and pointer-events:auto — a near-fullscreen div that both hid the
model and swallowed mouse events, so orbit drags over most of the canvas
did nothing. Move it to a small bottom-left box, set pointer-events:none
so it never intercepts navigation, and collapse it to a few dimmed lines
once the app goes live (errors re-expand it). It still auto-scrolls to
the newest line.

Dion Moult e3722cf243 ifcviewer-web: load user sidecars via a file-browse button (#46)
Adds an "Open .ifcview…" button that opens the browser's native file
chooser. The picked file's bytes are written into MEMFS and a new
exported entry point, load_uploaded_model_c, reads them back via the
existing loadSidecarFromPath: it resetScene()s the current model
(replace, not append), loads the sidecar, and viewAll()s it. Geometry
becomes resident over subsequent frames through render()'s inline
driveStreamingLoads, same as the embedded sample.

Deliberately a file picker, not drag-drop: browser file drag-drop needs
an X11 drag source (a file manager) to drag *from*, which a minimal WM
(ratpoison) doesn't provide. The native chooser is WM-independent.

Exports _load_uploaded_model_c and the FS runtime method; URL/byte-range
fetch of remote models stays for #88.

Dion Moult d36d241da2 ifcviewer: size streaming pool to demand instead of probing for the max
The desktop pool walked down from 4 GB looking for the largest single
buffer the runtime would grant, then used that as the pool's first
sub-buffer and growth increment. On a stack that advertises an
effectively unbounded maxBufferSize (1 TB observed on wgpu-native here)
the walk lands on 2 GB, so loading even a 1.2 MB model allocated a 2 GB
sub-buffer. That plus the depth/MSAA/HiZ/pick attachments exhausted
VRAM, and the next tiny allocation — the ~4 KB selection_flags buffer —
failed with "Not enough memory left", invalidating its bind group and
panicking wgpuQueueSubmit.

Drop the probe and size the pool to demand, mirroring the web path:
configure a modest initial sub-buffer and let BufferPool::addSubBuffer
grow it lazily (halve-retrying to its 64 MB floor on constrained
devices). A single chunk is capped at 16 MB, so the initial sub-buffer
only has to clear that. Web keeps its 64 MB initial (Chrome contends on
large first allocations); desktop uses 256 MB to keep sub-buffer count
low for big models. The two platforms now share one createPool() (was
probeAndCreatePool — it no longer probes).

Dion Moult c0c0c987c4 ifcviewer-web: wire mouse + wheel navigation (#85)
Register emscripten HTML5 pointer/wheel handlers that translate raw
events into ViewportCore::orbitBy / panBy / dollyBy: left-drag orbits,
middle/right-drag pans, wheel zooms. mousedown binds to the canvas;
mousemove/up bind to the window so a drag keeps tracking off-canvas. A
contextmenu suppressor lets right-drag pan without the browser menu.

Pure callbacks — no Asyncify, no sync spin — so none of the web init
gotchas apply. Pick stays deferred until the async buffer-readback
rewrite. The embedded sample is now navigable on Chrome + Firefox.

Replace the inline orbit/pan/wheel math in ViewportWindow's mouse
handlers with calls to ViewportCore::orbitBy / panBy / dollyBy. The core
methods request the frame (via the host), so the now-redundant
requestUpdate() calls drop out; the pivot-indicator afterglow and 3px
drag-promotion stay in the Qt layer where they belong. Behaviour is
unchanged.

Dion Moult 1d13b05acf ifcviewer: add incremental orbit/pan/zoom to ViewportCore (#85)
The orbit navigation math lived in the Qt ViewportWindow, operating on
ViewportCore's camera fields through references. That left the web host
with no way to drive the camera — orbit/pan/zoom were Qt-only.

Lift the three pixel-delta moves into ViewportCore as orbitBy / panBy /
dollyBy so every host (Qt desktop + web) shares one implementation and
the math can't drift between platforms. panBy takes the viewport height
as a parameter (the one Qt coupling: pan's world-units-per-pixel needs
it) so the core stays toolkit-free.

Petru Conduraru fce7cd3eb4 test(ifcpatch): add MergeProjects regression test for merging 3+ files (#7973)
Merging more than two IFC models with the MergeProjects recipe leaves
duplicated IfcGeometricRepresentationContext entities behind. All elements
are kept, but the accumulated contexts cause later disciplines to appear
"not merged" in viewers.

This test merges three projects and asserts the elements are kept, a single
IfcProject remains, and the geometric contexts are reused rather than
accumulated. It currently fails on the context assertion, reproducing #7973.

Gorgious56 f60a3423d0 Fix: commit pending parametric draft before extrusion-edit
EnableEditingExtrusionAxis and EnableEditingExtrusionProfile both
import a mesh from the IFC representation into obj.data as their
first real action. That mesh-import overwrites any in-memory
parametric (gizmo) draft on the object, silently discarding the
user's pending dimension edits.

Concrete reproduction: drag a wall's length gizmo (draft pending),
then click "Edit Axis" before validating the draft. The axis-edit
imports the wall axis mesh; the in-flight draft vanishes; on
cancel the wall snaps back to its pre-drag length.

Both call sites now commit the active draft via
tool.Parametric.commit_object_draft before the mesh import, gated
on tool.Parametric.is_object_editing so the guard is a no-op when
no draft is in flight.

Gorgious56 006a24ef32 Refactor: rename rel -> subject in disconnect_rel dispatch
The "mep-pair-fitting" kind added in the previous commit carries an
IfcFlowFitting (the entity whose deletion disconnects the pair), not a
relationship entity, in the dispatch slot — but the slot was named ``rel``
across the function signature and every call site. Rename to ``subject``
so the parameter name reflects the uniform intent: "the entity whose
teardown effects the disconnect", regardless of whether that's a rel or
a fitting.

Sweep covers:

- core.connection.disconnect_rel signature + body
- tool.Connection.find_rels / find_rels_for_element / find_rel docstrings
- The cascade-on-delete call site in tool.Geometry.delete_ifc_object
- DisconnectElements operator in bim.module.model.wall
- All affected test kwargs and AST forward-compat docstring
- Error message: "Unknown rel kind" -> "Unknown kind"

No behaviour change.

Gorgious56 6fa984ce2b Fix MEP pair-disconnect crash and bend re-edit pen icon
Three user-facing fixes for the MEP-system gizmo surface:

1. MEP pair-disconnect no longer crashes Blender. The
   MEPSystemPathDecorator cached entity_instance references in
   _cached_walk; deleting a bridging fitting via the gizmo left a freed
   SWIG handle in the list, and the next _build_geometry pass segfaulted
   on .is_a. The cache now stores STEP integer ids and re-resolves via
   ifc_file.by_id on each draw, plus folds tool.Parametric.get_geom_generation
   into the cache key — ifcopenshell.api mutations invalidate before the
   next frame regardless of how the deletion was routed.

2. Bend re-edit pen icon stays reachable. The bend creation path
   tessellates the swept-disk body (upstream geometry-kernel workaround),
   so tool.System.has_parametric_body correctly returns False for a
   freshly-committed bend. _active_is_bend_fitting and
   GizmoMEPActions.is_eligible_object now fall back to the type's
   BBIM_Fitting pset — the same source bim.enable_bend_preview_from_bend
   reads parameters from — keeping the pen icon eligible.

3. MEP pair / per-port unjoin icons unified through bim.disconnect_elements.
   The MEP gizmo group's three unjoin icons (pair, start, end) now share
   the wall-disconnect surface: same VIEW3D_GT_wall_link_toggle icon, same
   bim.disconnect_elements operator. tool.Connection.find_rels learned a
   new "mep-pair-fitting" kind that returns the bridging fitting as the
   disconnect target; core.connection.disconnect_rel grew the matching
   dispatch arm. The old MEPUnjoinAtPort and MEPUnjoinPair operators are
   removed.

Also registered wall.GizmoPairDisconnect (previously declared but never
in the classes tuple, so dead code) for the wall+slab pair-disconnect
surface, and extracted MEP port-topology helpers (find_bridging_fitting,
is_disconnectable_fitting, neighbours_at_ports) onto tool.System so the
canonical walk has a single home.

Gorgious56 44c0c2916c Bonsai patch: lossy-downgrade popup + per-recipe preset menu
Two new UX features in the IFC Patch panel, both backed by helpers on
bonsai.tool.Patch.

Lossy-downgrade confirmation popup. When the user picks the Migrate
recipe with a target schema older than the source's (IFC4 -> IFC2X3,
IFC4X3 -> IFC2X3), ExecuteIfcPatch.invoke shows a properties dialog
listing what's preserved vs lost: IfcIndexedPolyCurve flattened with
arcs approximated, IfcPolygonalFaceSet / IfcTriangulatedFaceSet
converted to IfcFacetedBrep, IFC4-only IfcElement subclasses (IfcLamp,
IfcPipeSegment, IfcGeographicElement, ...) demoted to
IfcBuildingElementProxy with the original class + PredefinedType
encoded into ObjectType, and PredefinedType enum values absent from
IFC2X3 dropped. The user explicitly approves before the recipe runs.

The popup is gated on tool.Patch.migration_is_lossy_downgrade() which
resolves the source schema via header-only parsing
(tool.Patch._patch_source_schema reads the first ~2KB and matches a
FILE_SCHEMA regex, then normalises via ifcopenshell.util.schema.
get_fallback_schema). Avoids a full ifcopenshell.open() on every
Execute click — multi-second saving on large files. The target schema
is looked up by argument name rather than position so it survives
recipe-parameter reordering.

Per-recipe preset menu. New BIM_MT_ifc_patch_presets + AddIfcPatchPreset
wire Blender's standard preset system into the panel. Each recipe gets
its own preset subdirectory (bonsai/ifc_patch/<RecipeName>/), so a
preset saved for ExtractElements does not pollute the Migrate preset
list. The preset operator uses Attribute.get_value_name() (single
source of truth for data_type -> storage-field mapping) to build the
preset_values list dynamically per recipe.

The recipe-change callback resets
BIM_MT_ifc_patch_presets.bl_label to the canonical title — Blender's
script.execute_preset mutates the menu's bl_label to the loaded
preset's name as a "currently-selected" indicator, and without an
explicit reset the previous recipe's preset name would falsely advertise
itself in the new recipe's menu.

tool.Patch gains get_preset_subdir, migration_is_lossy_downgrade,
_patch_source_schema as cross-cutting helpers. _SCHEMA_AGE module
constant provides the ordering used by the downgrade-detection
predicate.

Test coverage: 12 bim-lane tests under test/bim/module/patch/. The
truth table for migration_is_lossy_downgrade covers IFC4/IFC4X3 source
x downgrade/upgrade/same-schema target x Migrate/non-Migrate recipe.
The schema-sniffing tests write a real IFC4X3_ADD2 file to disk and
assert the helper resolves it to IFC4X3 (regression for the original
startswith iteration-order bug). An end-to-end test drives
bpy.ops.bim.execute_ifc_patch with an in-memory IfcLamp source and
verifies the on-disk IFC2X3 file contains a single
IfcBuildingElementProxy with ObjectType "IfcLamp/COMPACTFLUORESCENT"
and the original GlobalId preserved.

Gorgious56 2ab5ca9222 ifcpatch: small recipe polish
ExtractElements: expand the `query` docstring to cover the exclusion
syntax (`!` on entity classes, `!=` on attribute / pset / material /
classification / location / group facets) and the "seed with a broad
include before subtracting" gotcha — entity-class exclusion does not
auto-seed from "all elements", so a bare `! IfcSlab` query returns
nothing.

FixArchiCADToRevitDoorSwings: guard the `IfcIndexedPolyCurve.Segments`
loop against the IFC4 case where Segments is absent (a polyline
through all coords in declared order). Previously crashed on
`None.__iter__`.

Gorgious56 f710929e9e ifcpatch Migrate: defensive IFC4/IFC4X3 -> IFC2X3 downgrade
The Migrate recipe previously crashed mid-loop with the cryptic
`RuntimeError: Entity with name '' not found in schema 'IFC2X3'` when
asked to downgrade an IFC4 or IFC4X3 file to IFC2X3 — the
class_4_to_2x3 mapping marks IFC4-only geometry / element classes with
an empty-string sentinel and the old code blindly forwarded that to
create_entity. Real files routinely contain IfcPolygonalFaceSet,
IfcTriangulatedFaceSet, IfcIndexedPolyCurve, IfcLamp, IfcPipeSegment,
IfcGeographicElement, etc.

The recipe now runs a preprocessing pipeline when the target is IFC2X3
and the source is IFC4 or IFC4X3:

- DowngradeIndexedPolyCurve flattens IfcIndexedPolyCurve to IfcPolyline
  for the whole file (arcs included — see below).
- IfcPolygonalFaceSet / IfcTriangulatedFaceSet are converted directly
  to IfcFacetedBrep at the entity level via
  ifcopenshell.util.shape_builder.polygonal_face_set_to_faceted_brep,
  preserving topology including IfcIndexedPolygonalFaceWithVoids inner
  bounds. IfcShapeRepresentation carriers have their RepresentationType
  tag updated from "Tessellation" to "Brep".
- Orphan source-only geometry instances (left over after the rewires)
  are purged iteratively via
  geometry_classes_introduced_after(target, source).

The Migrator is invoked with fallback_element_to_proxy=True so
IFC4-only IfcElement subclasses (IfcLamp, IfcPipeSegment,
IfcGeographicElement, ...) become IfcBuildingElementProxy in the
output. A post-pass encodes "<OriginalClass>/<PredefinedType>" into
ObjectType (e.g. "IfcLamp/COMPACTFLUORESCENT") when ObjectType is
empty, so the lost subclass identity survives the downgrade as
searchable text.

The migration loop now collects per-entity failures into a list rather
than crashing on the first; a summary RuntimeError fires at end if any
failed, naming up to 20 with their inverse references. Successful
migrations log a single count line via self.logger.

DowngradeIndexedPolyCurve extended:
- Arc segments (IfcArcIndex) are flattened via
  ifcopenshell.util.shape_builder.arc_to_polyline_points with
  ARC_SUBDIVISION=16 chord points per arc.
- Multi-index IfcLineIndex segments handled correctly.
- Absent Segments list (IFC4 polyline-through-all-coords case) handled.

Test coverage: 11 tests across the two recipes covering all four
preprocessing branches, the IFC4X3 source gate, the ObjectType
encoding (incl. author-supplied ObjectType preservation), the summary
RuntimeError shape, and the arc subdivision.
