Highlights

Coordination Hub — unified KPI dashboard aggregating clash/rule-pack/federation/BCF/smart-view counts with a colour-coded health banner, glass-effect cards, and quick-action tiles.

Smart Views v1 — rules-not-snapshots BIM saved-view system: per-project presets, expression rules, share-by-link via signed itsdangerous tokens, scoping (project / federation / personal).

Clash Smart Issues + AI Triage + Cost Impact — deterministic SHA-1 signature lifecycle, persisted LLM verdicts with confidence scoring, monetary roll-up per clash via clash_cost_impact module.

BCF 3.0 + OpenCDE — defusedxml-hardened reader/writer, 14 OpenCDE REST endpoints with ETag/If-Match concurrency control, full buildingSMART 3.0 spec compliance.

BIM Requirements (rules-as-code) — YAML safe_load engine with custom strict loader, blocked !!python/* tags, 8 seed packs including LOD 300, LOD 400, COBie handover, MEP clearance, DIN 276, fire-compartment property, room-naming convention, clearance corridor.

Federation Type Tree + federated viewer — slice 2/3 of multi-model BIM, deterministic discipline palette, dispose-safe Three.js lifecycle.

Editable Permissions Matrix — full role × permission grid with lockout protection (cannot self-demote admin), audit logging on every change, optimistic UI with rollback.

AI Estimate redesign — glass-effect UI, AbortSignal-threaded streaming, localStorage history (20-entry LRU), 6 example prompts, sanitised user input.

Module-presence dimming — sidebar visually fades modules with no data for the active project; 57 concurrent asyncio.gather probes complete in <200 ms.

Sidebar deep restructure — Estimation split into Estimating + Catalogues & Reference, lifecycle-ordered groups (Commercial → Planning → Operations → Comm → Docs → Quality → Safety → Finance → Analytics), Assets moved from Documents to Field Operations, visual separator before Regional.

About Changelog — two-column CSS layout with full v1.x–v3.x historical fill (118 entries).

Fixed

  • clash_ai_triage replay IDOR on NULL clash_id
  • bim_requirements /template/ missing permission gate
  • clash_cost_impact 404/403 timing oracle
  • BCF upload-cap mismatch (clash 25 MiB vs bcf 100 MiB)
  • NOTICE.frontend.json regeneration for v4.1.0+
  • Single-head alembic chain through v41_coordination_thresholds

Compliance

AGPL-3.0 maintained — no IfcOpenShell, no OpenCascade, no GPL-2-only deps.
