Overview

Extracts database schema information — tables, columns, indexes, and foreign keys — from a live ActiveRecord connection when available, or by text-parsing the schema file when no connection is present (CI, Claude Code, offline environments). The static fallback prefers db/schema.rb (RailsAiBridge::Introspectors::Schema::StaticSchemaParser) and falls back to db/structure.sql (RailsAiBridge::Introspectors::Schema::StaticStructureSqlParser) for schema_format = :sql apps.
