module Prostore::Drift::Detector

Overview

Drift detection (ADR-0010).

Compares the library's record of the schema (prostore_schema rows) against what's actually in the database. Resolution:

• Managed column renamed externally → auto-fix (rename back)
• Managed column dropped externally → ERROR (data lost)
• Managed column type/nullability altered → ERROR (ADR-0003)
• Managed index dropped or renamed → auto-fix (recreate / rename back)
• Unmanaged column / index / table → tolerate (log)
• Unmanaged name collision with desired → ERROR

The detector is a pure function over (live state, schema rows). The runner prepends the auto-fix operations to its plan before the model-driven diff runs.
