The Open Semantic Interchange (OSI) v0.1.1 spec was finalized in
January 2026 by Snowflake, dbt Labs, Salesforce, Atlan, Mistral, and
ThoughtSpot. None of them ships a YAML-first authoring tool. v1.7.0
is DataLex stepping into that gap.

Headline:
  - OSI v0.1.1 export through HTTP, MCP, and a frontend Export OSI button
  - visibility: gate (internal artifacts skipped from agent context)
  - Custom-extensions provenance for round-trip back to source YAML

Conceptual modeling overhaul:
  - Inline-edit Selected Concept (domain, owner, tags, terms, definition)
  - Quick-add concept form (no dialog round-trip)
  - Verb autocomplete sourced from project + 19 common verbs
  - Bidirectional concept ↔ glossary linking
  - AI conceptualizer now generates business-meaningful verbs (places,
    contains, generates, depends_on, …) instead of 'X references Y'
  - Narrative DocsView for conceptual files: domain TOC, business flow
    sentences, per-concept paragraphs

Tests:
  - api-server 153 → 160 (+ 7 OSI export tests)
  - web-app 115 (still passing after DocsView/Build/Dictionary refactors)
  - python 18 → 23 (+ 3 conceptualizer verb + 5 OSI exporter tests)
