Module Utils/IntelligenceIndex

Description

Stable barrel re-export of the cross-article intelligence indexing system. The original 858-LOC module was split (issue #2032) into focused submodules under src/utils/intelligence/. This barrel preserves every public import path used by consumers in src/ and scripts/.

Sub-module layout:

• src/utils/intelligence/types.js — re-export of the index data types
• src/utils/intelligence/build.js — index construction & queries
• src/utils/intelligence/persist.js — load / save with schema normalisation
• src/utils/intelligence/trends.js — trend detection
• src/utils/intelligence/html.js — "Related Analysis" HTML renderer
• src/utils/intelligence/internals.js — shared helpers (private)
