New OverlayRenderer module owns every client-supplied overlay primitive
drawn after the main pass: tinted, depth-aware highlight triangles via
its own GL shader, and top-left HUD text via QPainter on a
QOpenGLPaintDevice. Public surface on ViewportWindow is just two
forwarders (setHighlightTriangles, setHudText).
ViewportWindow's MeshLocalPick now exposes the instance's composed
transform so consumers can map mesh-local geometry back to world
space without re-querying. AreaMeasurement uses both: its selection
key is now (object_id, tri) so per-instance highlighting works for
two distinct walls sharing a mesh, and on every pick it rebuilds the
world-space tri list and the HUD readout.

Adds a click-to-measure area mode triggered by Ctrl+Shift+A. Each LMB
click expands the picked triangle into its connected coplanar patch
(BFS over shared edges, dot(normal, seed) > 0.9999); re-clicking
removes that patch; Alt+LMB skips expansion for a single triangle.
Picks across different meshes accumulate as separate patches.
ViewportWindow gains pickMeshLocalAt (screen pick → mesh-local hit
via inverse composed transform) and a tool-mode pattern mirroring
the section tool (toggleAreaTool, surfacePickedInTool signal,
areaToolToggled signal, Esc to exit). Per-mesh adjacency is built
lazily on first pick of each mesh and dropped on tool toggle.

Adds neutral primitives on ViewportWindow (readbackMeshTriangles,
findInstance) so consumers can compute per-object geometry queries
without the library retaining a CPU triangle copy. Measurement.cpp in
ifcviewer-full uses them to sum signed-tetrahedra in mesh-local space,
weighted by |det(placement_3x3)| per instance for mapped-item scaling.

Read-only handles reject Flush/CompactRange, so the destructor's status
assertion always fired on shutdown when the streamer's sidecar was
opened with read_only=true. Track the flag and skip the write path; also
guard against a null db when the initial open failed.

Federation gains a nested Group tree (id, display_name, visible,
children); models reference a single group via Model::group_id.
Visibility cascades: a model is effectively visible only when its own
flag is on and every ancestor group is visible. Persistence nests
groups directly in the JSON — no parent_id field.
ifcviewer-full surfaces this in the element tree with right-click
menus to create / rename / move / remove groups, move models between
groups, and toggle group visibility.

Right-click a model root in the Elements tree to get Hide/Show and
Remove. Hide flips the federation's per-model visible flag (already
round-tripped to .ifcfed), pushes ViewportWindow::hideModel/showModel,
and italicises + greys the tree root as a visual cue. Remove drops
the model from the viewport, the SceneLoader (streamer + caches), the
MainWindow UI maps and tree, and the Federation — disabled while the
model is the active load.
Visibility is reapplied on each model's load completion (sidecar or
stream), so a federation saved with hidden models opens with them
hidden. clearScene() now also drops SceneLoader state so streamers
no longer leak across federation transitions.
API additions:
- Federation::setModelVisible + modelVisibilityChanged signal
- SceneLoader::removeModel + isLoadingModel
Tests cover the setter (dirty + signal + idempotence + unknown id);
extends the existing round-trip test to actually exercise the
visibility load/save it always claimed to.

Commit f7add7f4 split getAxis2Placement out of an anonymous helper in
Geolocation.cpp into a shared Placement.{h,cpp}, but the test_federation
target's source list wasn't updated. The test binary failed to link
with `undefined reference to getAxis2Placement(express::Base const&)`
from Geolocation::getWcs. Add Placement.cpp to the explicit-source
list — it has no Qt dependency, only ifcparse.

When the user adds a model into a fresh, untitled federation that still
has the default (0,0,0, no rotation) FederatedFalseOrigin, derive an
origin from the first instance's placement_transformation (lifted
through CoordinateOperation when enabled) and the helmert grid-north
baked into ModelGeoref::coordinate_operation_meters. Multi-file batches
naturally settle: whichever load finishes first anchors the federation,
the rest see a non-default origin and skip. Saved .ifcfeds keep their
authoritative origin.
Adds Placement.{h,cpp} (port of util/placement.py — a2p,
get_axis2placement, get_local_placement) so Geolocation no longer needs
its own anonymous getAxis2Placement, and xaxis2angleDeg in Geolocation
mirroring util/geolocation.xaxis2angle.
SceneLoader captures the first instance's placement_transformation from
either the sidecar's InstanceCpu[0] or the streamer's first
InstanceChunk, so the guess works on both load paths without re-reading
the IFC.

Previously, applyCoordinateOperationToViewport — which pushes both
CoordinateOperation and ModelTransformation — was only called on
paths that required the IFC source to be loaded
(onLoadedFromStream and onDataSourceReady). Sidecar-only loads
(loadDataSource off, or no .ifc/.rdb sibling) silently lost both
stages.
Cache the per-model georef + unit scales in the sidecar itself so
the IFC source isn't needed to apply them:
SidecarData gains
coordinate_operation_meters[16] // column-major
project_length_to_meters
map_unit_to_meters
has_coordinate_operation
148 B fixed block written/read between instances and elements.
SIDECAR_VERSION 10 -> 11; existing sidecars rebuild on next load.
MainWindow::writeSidecarForModel populates the block from
loader_->modelGeoref(mid) before writeSidecar.
SceneLoader::applySidecarData restores it into the model's
ModelGeoref + sets has_georef = true, so subsequent
loader_->modelGeoref(mid) calls return the cached data without
needing the IFC.
MainWindow::onLoadedFromSidecar now calls
applyCoordinateOperationToViewport(mid) directly — both
CoordinateOperation and ModelTransformation land at sidecar-load
time, no longer waiting on a possibly-never-arriving data source.
Edits to the IFC's IfcMapConversion don't invalidate the cache —
delete the .ifcview manually if the source's georef changes. This
matches the existing cache-invalidation contract.
Tests: round-trip the new fields through the existing sidecar
fixture; assert SIDECAR_VERSION == 11.

Tree -> viewport selection was already wired (onTreeSelectionChanged
calls setSelectedObjectId), but pressing F afterwards routed to the
focused tree widget rather than the viewport, so framing didn't fire.
Add a window-level View > Frame Selected QAction with Qt::Key_F that
delegates to ViewportWindow::focusOnSelectedObject — works regardless
of which child widget has focus. The viewport's own F handler stays
in place for when the viewport itself owns focus.
For debugging coordinate problems, add View > Print Selected Coords
(Ctrl+Shift+P) -> ViewportWindow::printSelectedObjectCoords, which
qInfo's:
- a sample vertex (first vertex of the selected mesh, decoded on
demand from the quantised VBO so no extra CPU storage is needed);
- placement_transformation (the per-instance matrix that maps the
sample vertex from mesh-local into the model's pre-georef frame);
- global = CoordinateOperation . placement_transformation (where
the IFC's own IfcCoordinateOperation has been folded in);
- the sample vertex transformed through both matrices.
The print is a no-op when nothing is selected or GL hasn't initialised.

ModelTransformationDialog edits one federation model at a time. Top
combobox picks the model; below it the form covers the four pieces
of authoring intent:
- AFrame radio: ModelLocal vs ModelGlobal
- Point A: 3 doubles, label switches between "model project length
unit" and "model map unit" with the radio
- Point B: 3 doubles in federation units (label reflects current
FederationConfig.unit_*)
- Rotation: rx/ry/rz in degrees, intrinsic XYZ
- Pivot: 3 doubles in federation units
Switching models discards unsaved form edits — Ok saves the
currently-visible model, Cancel discards. On Ok calls
Federation::setModelTransformation, which fires
modelTransformationChanged → MainWindow recomposes that model in
the viewport.
Reachable from File > Model Transformations.
End-to-end is now editable: open a federation, edit federation unit /
false origin from one dialog, edit any model's transformation from
the other, watch the viewport recompose live. Visual verification
on a real model still pending.

New FederationSettingsDialog edits the federation-wide unit and the
FederatedFalseOrigin (XYZ + Z-rotation in that unit). On Ok it calls
Federation::setConfig + setFederatedFalseOrigin, which fire the
granular Federation signals MainWindow listens to → viewport
recomposes immediately.
Reachable from File > Federation Settings. Unit picker is a fixed
combobox of common length units (metres / mm / cm / km / ft / in /
yd / mi); each item carries (prefix, name) in itemData so saving
round-trips correctly. Per-model ModelTransformation editor still
to come — that's a per-model dialog reachable from the model entry,
not the federation-wide settings.

Federation grows three granular signals so consumers can recompose only
what's affected:
- configChanged() — federation unit changed
- federatedFalseOriginChanged() — stage 3 changed
- modelTransformationChanged(fed_id) — stage 4 changed for one model
Emitted from setConfig / setFederatedFalseOrigin / setModelTransformation
in addition to the existing dirtyChanged.
MainWindow gains applyFederatedFalseOriginToViewport and
applyModelTransformationToViewport helpers. Each composes the matrix
from the current federation state (using composeFederatedFalseOrigin /
composeModelTransformation, which already exist on Federation.h) and
pushes to the viewport's setFederatedFalseOrigin /
setModelTransformation. ModelTransformation reads ModelUnits and the
active CoordinateOperation matrix from SceneLoader::modelGeoref so
ModelLocal-frame `a` lifts correctly through stage 2 when authored.
Wiring:
- federation.federatedFalseOriginChanged -> applyFederatedFalseOriginToViewport
- federation.configChanged -> stage 3 + walk all models for stage 4
- federation.modelTransformationChanged -> stage 4 for that one model
- applyCoordinateOperationToViewport now also re-pushes stage 4 (the
compose result depends on the active stage 2 when a_frame is ModelLocal)
- openFederation() pushes the loaded FederatedFalseOrigin once load
completes; per-model stage 4 falls out of the existing
onLoadedFromStream / onDataSourceReady path.
End-to-end pipeline is now active under the AppSettings toggle: edit
the federation in memory and the viewport recomposes immediately. UI
for editing (form-based dialog) still pending.
