🔐 Governed domain lifecycle

The old single "Active" toggle is gone. Every domain version now flows through a proper, server-enforced state machine: DRAFT → IN-REVIEW → PUBLISHED. Only DRAFT is editable, only PUBLISHED is served to the API/MCP, and a colour-coded status badge follows every domain everywhere.

✅ Validation & Review workflow

A new Validation workspace plus a cross-domain My Tasks worklist let business users run consistency checks, sign off through a per-domain quorum-gated review, and keep a full audit trail — every decision logged with actor, transition, and comment (admins can override).

💬 Graph Chat now streams (SSE)

Tool calls and the final reply stream token-by-token — no more static "Thinking…" placeholder.

📄 Ingest binary documents

Drop in PDFs, Office docs, and images for OWL / business-rules generation — converted to markdown on the fly via Databricks ai_parse_document.

🧹 Cleaner ontologies by default

The OWL generator now owns a validate → fix → re-validate loop and iterates to a zero-warning ontology out of the box.

🎨 Business Views overhaul

A guided New Assistant (seed entities + neighbours with a 1–3 hop control), collapse/expand entities, right-click "Hide from view", and a tidy icon-only toolbar.

📊 Build tracing & analytics

An immutable build_runs registry records every build (UI / API / scheduler), surfaced through a Build Analytics panel and a domain-wide audit trail.

🗄️ Graph / registry Lakebase separation

Run your graph DB in a separate Lakebase project, with an in-app Create Graph DB provisioner and a new Settings → Permissions tab.

🧪 Quality engineering at scale

The test suite grew from ~1,900 to 2,660+ cases across unit, integration, property, live, and e2e tiers — plus coverage gates, an LLM eval harness, ruff/mypy baselines, and pre-commit hooks.

⚙️ One-knob deploys

The Lakebase deploy-config collapsed from 13 variables to its core — a second instance now needs only DEFAULT_APP_NAME changed. deploy.sh gains colour logging, preflight checks, and a --dry-run mode.

⚠️ Upgrading from 0.4.x? Run the Lakebase migration (make bootstrap-lakebase or scripts/upgrade_lakebase_0.4_To_0.5.sql) — it backfills your active domains to PUBLISHED so they keep serving.
