clear_filtersRemove every filter — text query, date range, attachment toggle — and return the reader to the whole mailbox in file order.

filter_by_dateNarrow the reader to a date range and/or change the sort order. Works instantly on any mailbox size because dates are already indexed. Updates what the person sees on screen. Does not do text search — that is scan_messages.

get_mailbox_statusReport whether an MBOX file is open in this tab and what is in it: message count, date span, how many messages the current filters match, and whether the mailbox is fully readable. Call this first.

list_messagesList messages currently shown in the reader, newest-first or in whatever order the page is sorted by. Returns index, date, sender and subject only. Cheap at any mailbox size. Use read_message for the body.

read_messageRead one message in full: headers, plain-text body, and the names and sizes of its attachments. Attachment contents are not available. Use an index from list_messages or scan_messages.
