pub const SCHEMA_USER_VERSION: i64 = 50;Expand description
Canonical value of PRAGMA user_version written after migrations.
Why 50 instead of CURRENT_SCHEMA_VERSION (15)?
user_version is a 32-bit integer that SQLite reserves for application use.
We deliberately set it to a project-specific marker (50 = decimal) so external
inspection tools (sqlite3 db.sqlite "PRAGMA user_version", the file command,
SQLite browser GUIs) can distinguish a sqlite-graphrag database from a generic
SQLite file at a glance. The application-level schema version (15, matching
CURRENT_SCHEMA_VERSION) is stored in the schema_meta table and exposed via
health --json/stats --json. Bumping migrations does NOT change this constant.
Refinery uses its own refinery_schema_history table for migration bookkeeping.
