editor: snapping overhaul — shared-wall rooms, deterministic slab elevation, cursor-true transfers (#458)
* fix(snapping): show alignment lines in all modes, snap only in lines; north export; R/T hint; grid default

- Alignment guides display in every snapping mode (grid/lines/angles/off);
  magnetic pull applies only in 'lines'. New isAlignmentGuideActive() predicate
  decouples guide display from the snap delta across all placement/move/draw
  producers (item, wall, fence, slab/ceiling/roof, column/shelf/spawn, door/
  window, MEP, 2D floorplan drafting, surface snap).
- Floorplan PDF export now rotates to north-up (FLOORPLAN_VIEW_ROTATION_DEG -
  building rotation), matching the on-screen aligned-to-north view.
- Item placement rotate hint collapsed to a single 'R / T  Rotate' row.
- Default item snapping mode changed lines -> grid.

* feat(walls): detect rooms across shared walls + tight connect-snap in all modes

Room detection: planarize the wall graph before face-finding — split straight
walls at T-junctions where another wall ends mid-span, so a room closed against
the middle of an existing wall is detected, not just isolated 4-wall rooms.

Auto-close: wire the wall builder's "Room (auto-close)" to the same room graph
via wallClosesRoom(), so drafting stops when a segment seals a room against the
existing structure — not only when the chain returns to its own start.

Connectivity snap: add a tight wall-connect snap (WALL_CONNECT_SNAP_RADIUS 0.05)
that also runs in grid/off/angles — within range of a wall (body or corner,
uniform radius) the endpoint sticks onto it and the beacon shows, so rooms close
in every mode. Lines keeps its wider magnetic radii. Gate alignment guides in
non-magnetic modes to the same connect distance so a corner dot no longer
magnetises the cursor from far.

Tests: cover T-junction detection + wallClosesRoom; update the item-default and
wall-split tests for the mode-driven behaviour.

* feat(surfaces): gate alignment guides to connect distance in non-magnetic modes

Port the wall drafting/endpoint gating to the shared slab/ceiling/roof snap
(resolveSurfacePlanPointSnap): in grid/off/angles, only anchors within the
connect distance are fed to the alignment resolver, so guides form to nearby
points and far corner dots stop lighting up from across the plan. Filtering the
candidates (local-frame, like the cursor) rather than the resolved guides avoids
the floor-plan view rotation baked into the guide coords. Lines mode keeps the
full-range guides; the surface wall connect-snap is unaffected.

* fix(slabs): deterministic wall-slab overlap via clipped overlap length

Wall elevation used ray-cast point samples that landed exactly on the
slab boundary for perpendicular walls, so whether a butting wall
followed the slab's elevation depended on which side of the slab it
touched. Clip the wall centerline and face lines against the polygon
and require >=5cm of on/inside length instead: walls along the slab
edge follow it on every side, point contact never does.

* fix(grid): lift lattice 1mm off slab tops; wall-align on wall-item move start

The horizontal snap lattice sat exactly at the followed surface Y, so it
z-fought elevated slab tops while moving items. The visual mesh now rides
1mm above; the grid event plane keeps the true height.

Moving a wall-hosted item showed a horizontal grid until the first
pointer move published a wall surface — the mesh fallback assumed UP.
Derive the host wall normal from the item mesh's world orientation
(local +Z faces out of the wall) so the lattice is wall-aligned from
the first frame.

* feat(editor): unify selection shortcuts + truthful select-mode hints

Shift+click now toggles selection membership in 3D like Cmd/Ctrl (and
appends on box-select release), matching the 2D floorplan. The HUD rows
describe what actually works in both views: move is plain left-drag (the
grip/dot), the two vague selection rows collapse into one Cmd/Shift
or-group, and the modifier-held variants (freely / with guides / bypass
snaps) are gone — guides follow the snapping mode now. Key pills join
with + for combos and / for alternatives; Shift renders as the shift
icon.

* fix(editor): group gizmos — reliable rotate grabs, mutual hide, snapping-mode integration

The group-rotate gizmo never received pointer events through the shared
invisible hit-area path (EDITOR_LAYER + custom raycast) in its portalled
context; its handlers now live on the visible arrow plus a plain
default-layer invisible torus, so hover and drag work with a fat target.

Group drags begin a handle-drag scope: each gizmo hides while its
sibling drags (the frozen corner goes stale), idle hints leave the HUD,
and the drag gets contextual hints — Shift free-rotation for rotate, the
snapping chips for move.

Group move joins the snapping-mode system via the 'item' context: Shift
cycles the mode, Ctrl the grid step (both read live mid-drag), and
'lines' runs the same Figma-style alignment as single-node moves against
the group's bbox anchors. Chip clicks now tick like the keyboard cycles.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(editor): group-move ticks in every snapping mode

Mirror the single-node move's sfx: emit per delta change rather than
only on grid crossings, so lines/off get the same rate-limited texture.

* fix(items): keep host transfers glued to the cursor

Moving between hosts used to diverge from the pointer and mangle state:

- Grab offsets: every surface anchor (wall / ceiling / shelf / item
  surface / floor) preserved the grab offset by re-seeding from the
  item's carried-over position on each new host, landing it far from
  the cursor. The grab offset now survives only on the original host
  and only until the item anchors anywhere else — after that every
  host (the original included) centers the item under the cursor.
  Applied uniformly to the placement coordinator and the window/door
  move tools.

- Rotation: detaching from a rotated shelf/table back to the floor kept
  the HOST-local yaw as the level yaw, visibly spinning the item. The
  detach now re-expresses the item's world yaw in the level frame.

- Elevation: the same detach wrote the level parentId to the store but
  not the draft ref, so the floor-elevation resolver bailed on its
  parent-must-be-a-level guard — the snap grid and the item stopped
  following slab elevations for the rest of the drag.

* fix(items): latch grab-offset forgetting across every host kind

Review follow-up (PR #458): unify the per-surface grab-forget rule into
one grabForgotten latch. A wall/ceiling item could not actually reach a
shelf or the floor (item-surface enter rejects attachTo assets), but a
wall item CAN anchor on a roof face — and returning to its original
wall then restored the stale grab offset. Roof-wall transitions (and
floor landings after a host visit) now trip the latch in the
coordinator and the window/door move tools alike.

viewer: Fix Dutch roof trim artifacts (#452)
* Add roof surface placement support for items

Items (e.g. solar panels) can now be placed on sloped roof surfaces.
The placement system computes euler rotation from the roof surface
normal so items sit flush on the slope instead of going inside.

- Add roofStrategy to placement-strategies with enter/move/click/leave
- Wire roof:enter/move/click/leave events in the placement coordinator
- Add calculateRoofRotation in placement-math using surface normals
- Support full 3D cursor rotation for sloped surfaces
- Items on roofs are parented to the level with world-space rotation

* Snap new walls to the floor below

Feed the walls of the level directly beneath the active one into the
draft snap pipeline as extra references, so a new wall can align with
the floor below. They share the same local XZ origin, and the list is
kept separate from the current-level walls so the measurement HUD and
wall splitting only act on the active level.

* Set Dutch roof shape defaults on type switch

Seed the Dutch shape parameters (waist width/height/length, top rake
thickness/length) with sensible defaults whenever a segment is created
as or switched to Dutch, so the gablet is well-formed regardless of
leftover values from the previous roof type.

* Use green accent for corner and endpoint snap markers

Color the corner/endpoint snap markers and the vertical cursor pillar
green across the 2D floorplan beacon, the 3D alignment guide dots, and
the wall snap beacon so snap targets read as a consistent accent.

* Add magnetic wall snapping to the roof tool

Snap roof draft corners onto wall corners, midpoints, crossings, and
bodies on the active level and the floor below, reusing the wall tool's
snap pipeline so the beacon and coloring match. The cursor's ground
dot/ring is hidden while a wall snap is active to avoid overlapping the
beacon glyph.

* Show cutaway outline while dragging roof trim

Slice an untrimmed segment volume generated from the live node instead of
the registry mesh, whose CSG rebuild lags a few frames behind the drag and
may still hold placeholder geometry — so the section outline now renders
deterministically. Use LineBasicNodeMaterial so the outline draws under the
WebGPU pipeline, and export generateRoofSegmentGeometry for the slice source.

* Fill and clip roof trim cutaway, gate it to active drag

Add a violet silhouette fill behind the cutaway outline, extend the
section slicing to angled diagonal/corner trims via a generic vertical
cut plane, and clip each slice to its footprint span so the infinite
plane no longer sprouts stray lines across the rest of the roof. The
cutaway now renders only while a trim handle is being dragged.

* Separate and extend Dutch roof end slopes

Pull the Dutch hip end slopes out of the watertight shingle shell into
their own slab wedge so they can be reshaped independently, and extend
each end slope inward up its own hip plane until the top edge meets the
gablet's inner triangle. Refactor roof-segment shape geometry into a
shared roof-segment-shape module.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* Render roof trim cutaway as a material-only section cut

Replace the triangle-mesh slicer with a CSG intersection of a thin slab
against the untrimmed roof shell, so the cutaway shows red only on real
material (wall + deck bands) and leaves the hollow attic empty. Add an
analytic surface-edge outline, style both solid red like a SketchUp
section, and make the cutaway persist whenever a segment is trimmed.

Keep the merged roof shell visible during trim editing (re-trimmed live
from each segment's drag override) instead of swapping in the per-segment
meshes, whose abutting end-cap faces showed as stray white planes the
commit never had. Extend each slab past free cut-line ends only — trimmed
ends clamp to the cut line — so the red section stays inside the trim box.

Re-export INTERSECTION from the viewer CSG surface for the editor.

* Outline roof cutaway by fill silhouette, restyle to destructive red

Derive the section-cut outline from the fill geometry's edges
(EdgesGeometry) so it traces the real cut shape — wall/deck band
boundaries and the hollow-attic edge — instead of just the top surface
line. Drop the fill to 85% opacity and recolor both fill and outline to
the app's destructive red, matching the delete/destructive UI.

* Include roof accessories in trim clipping and red cutaway

Roof accessories (chimney, vents, skylight, dormer, gutter, downspout,
solar-panel, cupola) now slice at the trim plane like the roof shell and
appear in the red section-cut while dragging a trim handle:

- Export clipGeometryBySegmentTrim from the viewer as a reusable
  segment-local trim-clip primitive.
- Add a shared useSegmentTrimClippedGeometry hook + TrimClippedMesh
  wrapper (nodes) that slice accessory geometry by the host segment's
  live trim override, so the cut tracks the drag.
- Wire the clip into all 11 accessory renderers, including skylight
  glass panes and dormer window glass/frame/sill.
- Feed every hosted accessory mesh into the editor's red cutaway, welding
  triangle-soup geometry (e.g. ridge vent) so CSG INTERSECTION yields a
  cross-section.
- Register skylight in the scene-graph tree-node map so it shows in the
  outliner when placed on a roof.

* Add smooth spline fences with editable curve handles

Fences can now be drawn as one continuous Catmull-Rom/Bezier curve via an
optional `path` (+ per-point `tangents`), selectable in a Straight/Curved
mode toggle. Selected spline fences expose draggable control-point dots
(hexagon) and symmetric tangent handles (circle) joined by a violet line,
editable in both 2D plan and 3D. Side-move arrows are dropped for splines.

point has been placed and a curve is actually in flight. The draft point count
is published from SplineFenceDraft into a small ephemeral editor store
(useFenceCurveDraft) that the contextual helper reads, mirroring the existing
useSegmentDraftChain pattern.

* feat(editor): 3D alignment guides for item/wall/fence move + placement

Bring Figma-style alignment guides into the 3D editor, reusing the shared
pure resolver (`resolveAlignment`) and ephemeral guide store
(`useAlignmentGuides`) that previously only drove the 2D floor plan.

Core:
- `alignment-anchors.ts`: node→anchor adapters (footprint AABBs, corner
  anchors, wall/fence segment anchors) + `refineGuidesToGap` so a guide's
  line and distance read to the candidate's nearest edge, not the far side.
- `bboxCornerAnchors` + corner-only footprint anchors so alignment locks to
  item edges, never centrelines.
- `resolvePointSnap` (point-coincidence variant; kept for future use).

Editor:
- `Alignment3DGuideLayer`: dashed ribbon + flat floor dots + distance pill,
  in the project's indigo accent, mounted inside ToolManager's building-local
  group so guides render in the cursor's frame.
- Producers wired in the item move tool, item placement coordinator, and the
  wall + fence endpoint tools; walls and fences cross-align.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(editor): align guides snap to nearest real anchor, drop bbox re-span

The 3D alignment guide could place its end dot in empty space: a diagonal
wall (or any rotated / non-rectangular object) has bounding-box corners that
don't lie on the object, and `refineGuidesToGap` re-spanned the guide to
exactly those AABB edges — so the dot floated "along the coordinate" rather
than on the item.

- `resolveAlignment` now tie-breaks to the candidate anchor NEAREST on the
  perpendicular axis (after the tightest axis match). Anchors are real points
  (corners / endpoints / midpoints), so the guide always connects to the
  closest actual point — which also yields the facing-edge gap distance.
- All four producers (item move, item placement, wall + fence endpoints) now
  publish the raw resolver guides; the AABB nearest-edge re-span is gone.
- Removed the now-dead `refineGuidesToGap` and `resolvePointSnap` helpers
  (and their tests / exports).

* feat(editor): group move handle + shared group-transform core, move-tool polish

Add a group-move gizmo alongside the existing group-rotate handle, both
driven by a new shared `group-transform-shared` module (participant
classification, group-box + corner math, connected wall/fence component
expansion so attached structure transforms rigidly as one piece).

- core: refactor alignment-anchors collection + tests, extend handle registry
- editor: group-move-handle, group-transform-shared; rotate handle reuses them;
  node-arrow-handles gains click-swallow guard; box-select + placement tweaks
- nodes: move-tool updates across ceiling/column/slab/roof/registry; door math
  and panel adjustments; item definition cleanup
- nodes(fence): play `sfx:grid-snap` ticker on endpoint move, matching the
  wall endpoint tool (fixes missing audio feedback on fence side drag)

* fix(editor): keep autosave alive across page unload

The autosave debounces writes by 1s and relies on a `beforeunload` flush
for anything still pending. That flush fired a plain `fetch` PUT, which
the browser cancels the instant the page unloads — so refreshing right
after an edit (e.g. painting a roof material) silently dropped the change
and the reload showed the last persisted scene.

Thread a `{ keepalive }` option through the save callback and set it on
the unload flush so the request survives the unload. Also listen for
`pagehide` (fires where `beforeunload` does not, e.g. mobile Safari /
bfcache) and clear the dirty flag up front so the two listeners don't
double-send. Normal debounced saves omit `keepalive` (its 64KB body cap
only constrains the best-effort unload flush, not regular saves).

* feat(editor): paint eraser + reset-all, drop roof cross-role bleed

Material paint gains an eraser (clear a surface back to its default) and a
"Reset all" action that defaults every painted surface on a node — for a
roof that includes each child segment — via a generic
`buildResetSurfaceMaterialUpdates` that nulls catch-all and role-specific
material fields without per-kind knowledge.

Also stop a single painted roof surface from bleeding onto the others:
`getEffectiveRoofSurfaceMaterial`, `getRoofMaterialArray`, and the segment
renderer no longer cross-fall-back between top/edge/wall. An unset role
resolves only to the legacy catch-all (back-compat) or the theme default,
so painting just the shingle, trim, or soffit stays on that surface.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(editor): alignment guides + drag bounding box across tools

Extend the Figma-style 3D alignment guides to the placement and move
tools for columns, elevators, roofs, stairs, ceilings, slabs, fences,
walls, doors, and windows: each collects alignment anchors from the
scene, resolves a snap within the shared threshold, and drives the
`useAlignmentGuides` overlay. Wall openings (doors/windows) only snap
along their host wall via the new `wall-opening-alignment` helper.

Add a shared `DragBoundingBox` overlay (exported from the editor barrel)
that renders the dragged object's bounds during a move, wired into the
column move tool alongside the alignment snap.

* fix(editor): axis-stable resize-arrow drag plane + slimmer gizmo handles

Build the linear resize-arrow's drag plane so it always contains the
handle's axis (view direction minus its along-axis component) instead of
a plane that merely faces the camera. The old camera-facing normal
collapsed when the axis pointed toward the viewer — screen motion barely
changed the axis component, so the resize crawled or stopped tracking the
cursor. Also slim the extruded arrow/handle geometry (shared by the node
arrows, wall side handles, and polygon editor) for a lighter gizmo.

* fix(editor): fill-block wall opening highlight + selected frameless openings

Draw the selected-wall opening highlight as a translucent block filling
the cutout volume (front-side culled) instead of a single vertical pane,
so it reads as an occupied slot from any angle — including a top-down
floorplan view where an edge-on pane was invisible. Also highlight a
directly-selected frameless opening (a `door` with openingKind
`'opening'`), which otherwise renders no geometry of its own, and reflect
live drag overrides via `useLiveNodeOverrides`.

* fix(viewer): double-side slab hole side-walls

Build the slab in 3D rather than via ExtrudeGeometry so each hole-wall
quad is emitted twice with opposite winding. The slab material is forced
to FrontSide (DoubleSide poisons the MRT scene pass), under which
ExtrudeGeometry's single-sided hole walls get back-face culled and you
see straight through the cut. The doubled quads keep the cut's inner
thickness visible from any angle without z-fighting.

* fix(editor): box-select building-scoped nodes like elevators

Building-scoped selectable nodes (e.g. elevators) are children of the
building, not the active level, so the level walk never reached them.
Also walk the level's building children and box-test any registry-
selectable kind by its rendered bounds, matching the column/stair/shelf
path.

* feat(editor): shelf placement alignment + column placement ghost

Shelf placement now snaps to Figma-style alignment guides by its
footprint edges (layered on grid snap, Alt bypasses), matching the
existing 3D move tool. Guides refresh after each drop and clear on
teardown.

Column placement migrates to the registry `def.tool` path so it can
render a translucent column ghost at the cursor (like the shelf build
tool) instead of a bare cursor sphere — the editor package can't import
the column geometry, so the tool now lives in packages/nodes:
- extract `ColumnBody` from the renderer and add a `ColumnPreview`
  (cloned translucent material, raycast disabled, origin-positioned)
- new `column/tool.tsx` registry placement tool with the same
  footprint-edge alignment as shelf / column move
- wire `def.tool` + tool hints; drop the now-unreachable legacy
  editor-side `ColumnTool` and its dead file

* feat(editor): floor-plan alignment, pivot moves & placement ghosts

Bring the 3D editor's Figma-style alignment experience to the 2D floor
plan across every node kind, fix pivot semantics on move, and add 2D
placement ghosts.

Alignment
- Wall anchors now include ±thickness/2 face corners so columns/items/etc.
  snap flush to wall faces (fixes pillar↔wall); shared by 2D and 3D.
- Shared apply-alignment helper (applyFloorplanAlignment /
  alignFloorplanDraftPoint, with excludeIds) used by move sessions,
  structural drafting (wall/fence/slab/zone/ceiling/roof), and wall/fence
  endpoint drags.
- Door/window/wall-item moves get along-wall edge-to-edge snapping.
- Generic free-translate move path aligns by edges (corner anchors).

Pivot moves (2D)
- Polygon kinds (slab/ceiling/zone) move by centroid→cursor via a shared
  polygon-centroid mover; stair moves by origin→cursor; matching 3D.
- Shelf/column move targets write position directly (single source of
  truth) so the 3D group no longer sticks on commit.

Placement ghosts (2D)
- usePlacementPreview store + FloorplanPlacementPreviewLayer render a
  kind's def.floorplan footprint following the cursor; wired for column
  and elevator.

Fixes
- Elevator placement no longer deselects the active floor plan
  (preserve levelId through setSelection's hierarchy guard).
- Guides clear on every commit/cancel/unmount path.

* refactor(editor): address architecture review for floor-plan work

- Move usePlacementPreview store from core to editor: placement ghosts
  are an editor/tool concern the read-only viewer never needs. Rewire the
  column tool (via the @pascal-app/editor public surface) and the
  editor-internal elevator tool + preview layer (relative imports).
- FloorplanPlacementPreviewLayer: read scene lazily in ctx.resolve instead
  of bulk-reading the nodes map during render.
- wiki/architecture/tools.md: refresh the stale useLiveTransforms-per-kind
  note to reflect item/shelf/column (world-plan) + slab/ceiling/zone (delta).

* fix(nodes): recreate window draft on wall:move when null after placement

After a successful click-to-place, the click handler deletes the
transient draft and relies on the wall-rebuild → R3F pointer-enter
cascade to create a fresh draft for the next placement. If that cascade
doesn't fire synchronously (e.g. async geometry rebuild) the next
wall:move receives a null draftRef and bails — requiring leave/re-enter
to place again.

Fix: in onWallMove, when draftRef.current is null but we're hovering a
valid wall, recreate the draft immediately (same WindowNode.parse +
createNode path as onWallEnter). This is idempotent: if wall:enter does
fire first, destroyDraft() in onWallEnter cleans up cleanly.

Preserves parity with door multi-place behaviour, matching #367's intent.

* fix(nodes): recreate door draft on wall:move when null after placement

Mirror of the window fix one commit back: after click-to-place the
DoorTool deletes its transient draft and relies on the wall-rebuild \u2192
R3F pointer-enter cascade to spawn a fresh draft for the next placement.
When that cascade doesn't fire synchronously, the next wall:move sees a
null draftRef and bails \u2014 forcing a leave/re-enter to place again.

Recreate the draft in onWallMove when null and over a valid wall on the
current level. Idempotent with onWallEnter (destroyDraft cleans up if
both fire).
