# RETIRED — TICKET-4
# This module has been deleted as part of the connector scan persistence fix.
# The async job-queue metadata scan path has been replaced by the synchronous
# /api/connectors/metadata-scan endpoint which writes to the unified
# sense_file_registry schema.
#
# If you see this file imported anywhere, that import is a bug — remove it.
