Migration

Migrations Live

Migrations use Alembic revisions with deliberate compatibility paths; API deprecations follow the documented 90-day policy.

• Schema — Alembic revisions, safe backfills, no production schema creation outside migrations.
• API — breaking changes require a new versioned prefix; the previous version stays supported for at least 90 days after notice.
• Deprecations — announced in release notes and the OpenAPI document.
