- task domain model + exhaustive §4.4 status machine tests (single source of truth)
- per-customer polling workers reconciled every 30s from the customers
collection; panic-safe runs; manual sync-now trigger; status provider
for the admin panel
- §5.3 upsert keyed on (system, key, customerId): refreshes content while
status=imported, records upstream_changed timeline + notification after
- attachments cached into GridFS via connector-authorized downloads
- orphaned tickets flagged with timeline + consultant notification, never
deleted; idempotent across polls
- consultant identity from users.extra.ticketingIdentities per system
- notifications store (insert/list/unread-count/mark-read)
