         * CLOSED ONE AT A TIME, THROUGH THE MODEL — [central-ticketing] #4781.
         *
         * This was a single `->update(['status' => 'closed'])`, which is one
         * statement and no model events. Since #4781 a ticket's status change is
         * an audited fact, and a bulk update would have left exactly one way of
         * closing a ticket invisible: the Changes log would show a ticket going
         * open → resolved and then nothing, while the row itself said `closed`.
         * "Who closed this" is the question the audit trail exists to answer,
         * and "the nightly sweep did, on this date" is a real answer — but only
         * if the sweep writes it.
         *
         * Per-ticket rather than one summary event because the answer has to be
         * on THE TICKET: the per-record history panel reads rows whose subject
         * is that ticket, and an aggregate "closed 14 tickets" row would not
         * appear in any of their histories.
         *
         * `chunkById`, so a first sweep over a long backlog does not load every
         * resolved ticket into memory at once. Paging by id is what makes this
         * safe while the filtered column is being written: each page continues
         * from the last id seen rather than from an offset, so rows dropping out
         * of `status = 'resolved'` cannot cause a page to be skipped.
