# Artifact-page saves used to land in the retired ``ArtifactCommit`` table.
# They now flow through :class:`FileCommitService.record_page_edit`, which
# writes one FileCommit + one FileCommitItem per save with the artifact
# columns populated (title/comments on FileCommit; diff/content_after_*/
# slug_kwd/page_type_kwd on FileCommitItem).
#
# ``file_id`` for these commits is a stable content-hash of ``(kb_id, slug)``
# so per-page history queries can filter on it without a real File row —
# no pseudo-File / virtual-folder machinery is created, so the workspace
# UI stays free of ghost entries.
#
# ``folder_id`` is set to ``kb_id`` directly. The datasets URL prefix
# (``/datasets/<kb_id>/commits``) resolves the entity id to itself for
# this scope; workspace file-commit browsing still uses ``/folders/*`` or
# ``/workspace/*`` with the real folder id.
#
# Content storage for ``content_after`` is switched by a module-level
# constant so ops can move blobs between MinIO and the doc-store index
# without touching the schema.
