-- Workspace deletion is application-owned. These statements form a fixed,
-- bottom-up deletion plan; the legacy foreign keys remain only as a
-- compatibility safety net during the expand phase.

-- name: SetWorkspaceTeardownMode :exec
-- The setting is transaction-local. Migration 242 makes only the three DELETE
-- dirty triggers skip their per-row work while this flag is on.
SELECT set_config('multica.workspace_teardown', 'on', true);

-- name: LockTaskUsageRollupForWorkspaceDelete :exec
-- The hourly rollup uses session advisory lock 4246. The transaction-scoped
-- lock shares that namespace: an in-flight rollup finishes first, then no new
-- rollup can write the workspace's aggregates until this delete commits.
SELECT pg_advisory_xact_lock(4246);

-- name: PrepareWorkspaceDeletionLinks :exec
-- Break self-references and the task/run cycle explicitly before deleting
-- either side. This keeps their ordering in the application-owned graph
-- instead of relying on ON DELETE SET NULL actions.
