Persistence

Standalone mode deliberately separates logical data stores:

Boundary	Current local store
Content and memory vertical	Local JSON by default
Management Plane	SQLite control-plane database
Runtime Runs and events	Independent SQLite runtime database
Work Plane and Workplace projections	Independent SQLite Work database plus local artifact files
Flow definitions, versions, drafts, Runs, and events	Independent SQLite Flow database

Every Workspace-owned query carries its Workspace identifier. Published Flow versions and agent revisions are immutable. Raw ingested source content is preserved and is never overwritten by normalized or generated output.

These stores are implementation details behind provider-neutral ports; no external database is required by default.
