🏗️ Pascal Editor v0.9.1 — Preset System, Rooms & Templates, Building Manipulation

This release ships a first-class preset system, room presets & template scans, a deep building-manipulation overhaul (rotation, unified handles, tap-to-engage move), editor sound design, viewer shadow improvements, and a full dependency/security refresh. It also publishes the npm packages announced in v0.9.0 — everything lands on the registry as 0.9.1.

✨ Features

• Preset system — capture builds as presets with framing + zoom-limited thumbnails, browse them in a hierarchical function-tree with an icon-grid category bar, and place them with parameters, move tool, shadows, isolation, and a green/red validity box (#341, #344, #345, #349, #354, #357, #366)
• Rooms & templates — save furnished rooms as reusable presets; template scans feed the same workflow (#390)
• Building manipulation overhaul — whole-building rotation with world-grid alignment, alt-click single-wall selection, tap-to-engage move (#388); live floor-stacking previews, unified handle system + hit areas, NaN-safe node mutations (#375); persistent site boundary handles (#386); alignment guides + floor-plan/3D placement parity (#372); level-scoped alignment, reference-floor symbols & registry slab tool (#373)
• Studio mode & inspector UX — studio mode, consolidated Display + References controls (#364, #370); build sidebar + slimmed items panel for the standalone editor (#361); vertical icon rail + headless inspector footer slot (#350)
• Sound design — structure build start/end cues, menu hover/click SFX (#378); per-kind delete sounds incl. shelf items (#379, #381)
• Roof accessories — gutters, downspouts & vents with gizmos (#355)
• Viewer shadows — shadow frustum fitted to building geometry and centered on focus (#347, #348)
• Fence presets — tool-defaults seeding + drawTool capability (#346)

🐛 Fixes

• Camera ↔ floor-plan navigation sync, both directions (#387)
• Editor interaction, loading, walkthrough, and IFC cleanup (#385)
• Relative move grab offsets + fresh placement commits (#383)
• Stair openings, roof-segment grid snap, 3D box selection, unit-aware alignment guides (#380)
• Slab side walls render solid regardless of polygon winding (#377); outline polygon edit handles + vertex grab (#365)
• Null-safety hardening across placement, cursor groups, box-select, and container renderers (#313, #323, #333, #342, #359); legacy door nodes normalized against the schema (#303)
• Nodes test suite repaired under bun (#360); stale registry + stair-opening tests updated (#358)

🧰 Infrastructure

• CI: lint + typecheck workflow (#369)
• June 2026 dependency refresh — next 16.2.6 (12+ security advisories patched; 16.2.7 deliberately held back for a Turbopack dev route-matching regression), TypeScript 6.0.3 everywhere, single-three dedupe, dead-dependency removal (#389)
• Architecture: enforced layer boundaries — ceiling dispatch, store relocation, shared helpers (#382); MCP plan↔world coordinate convention documented (#356)

📦 Packages

The 0.9.0 versions announced in the previous release never reached npm — they ship here as 0.9.1.

🌍 Pascal Editor v0.8.0 — Community Sync & MCP on npm

This release brings our community-driven improvements into the open-source packages, and marks the first public npm release of @pascal-app/mcp — the Model Context Protocol server for Pascal.

📦 New Package: @pascal-app/mcp

@pascal-app/mcp is now available on npm!

npm install @pascal-app/mcp

The MCP server exposes the Pascal scene graph to AI hosts (Claude Desktop, Cursor, and any MCP-compatible client) via the Model Context Protocol. It ships with:

• 19 MCP tools — scene querying, mutation, undo/redo, export, validation, and vision
• 4 MCP resources — current scene, summary, item catalog, and level constraints
• 3 MCP prompts — from_brief, iterate_on_feedback, renovation_from_photos
• stdio and Streamable HTTP transports
• pascal-mcp CLI binary with --stdio, --http, and --scene flags
• Local SqliteSceneStore backed by built-in SQLite (Bun/Node), shared across MCP and the editor via PASCAL_DATA_DIR / PASCAL_DB_PATH

✨ Changes

• Item catalog schema — items now carry source (library | community | mine) and isDraft fields, enabling the editor's Library / Community / Mine filter panel
• Grid events — GridEvent gains faceIndex and object fields for more precise hit-testing
• Material library — typed target-set constants (WALL_TARGETS, STAIR_TARGETS, etc.) for the material paint mode
• Stair system — overhauled renderer with improved geometry and material handling
• First-person controls — BVH collider improvements and more reliable character movement
• Guide system — updated snapping and measurement guides
• Scan system — improved point-cloud handling
• Shared elevation styles — new styles/elevation.css usable across apps
• Build — hoisted platform-specific optional native packages at the root; TypeScript import type cleanup throughout

🐛 Fixes

• CSG geometry disposal in wall generation (memory leak fix)
• Stair opening sync stability
• Wall curve and mitering edge cases
• Space detection improvements

📦 Packages
