Unreleased (v0.2 in progress)

Script-as-source (M5)

Python build scripts became the single source of truth for IFC: script contract (PARAMS + deterministic GlobalIds + build entry), sandboxed script execution, WPS-style script staging + paired major-version snapshots (scripts/v{n}.py + versions/v{n}.ifc).
Script diffs (text + PARAMS key-level, major/minor two levels); Design panel rebuilt as a PARAMS form + script editor; the design JSON editing pipeline was removed.

MCP & user provenance

New mcp-server: a thin MCP wrapper (stdio) around the editing API that parses user-modified IFC/DXF files and tags them with USER provenance (extended from UI/AI).

Direct real property editing

Property editing no longer has an override layer — it goes straight through the pending → commit real-edit loop; new editable-schema and element-deletion endpoints; PropertyPanel rebuilt with typed forms.

Fixes & misc

ChatSidebar history/SSE merge fixes and EventSource resilience with reconnect.
edit-service image ships bwrap and binds to loopback; CI gained an mcp-server job and a real compose smoke test.

Review platform

IFC upload with queued conversion (XKT geometry + semantic metadata); model tree, property inspection, visibility tools, section planes, measurements, NavCube.
Issues & 3D pins with camera view and screenshot capture, status flow, click-to-locate.
File / PostgreSQL dual implementations for issues, overrides and change log.

Real IFC editing & versions

edit-service (FastAPI + IfcOpenShell): property overrides and a two-phase pending → commit real-edit flow, immutable version snapshots, attribute-level semantic diffs keyed by GlobalId, Diff Viewer.

AI integration

Humans and AI share the same REST editing API (distinguished by provenance), with an OpenAPI tool catalog and integration guide.
The aiifc modeling skill: agent-agnostic, lets AI write ifcopenshell.api code directly to generate or heavily modify IFC models; includes a Plan → DXF → IFC three-stage orchestration workflow and a DXF generator.
Deterministic element identity: stable key → uuid5 deterministic GlobalId → Pset_AIIFC.designKey bidirectional mapping.

Engineering

Uniform versioned API /api/v1/{resource}/{id} with the Go server as the single entry point and a unified envelope contract.
Self-contained dependencies (ifcopenshell / ifcdiff / ifcquery all from PyPI); this VitePress documentation site with an English locale and machine-generated API reference with CI drift detection.
Legacy SCAD code moved to the private archive repo 0702hjj/SimpleCADAPI-archive; this repository focuses on the viewer/ product.
