/**
 * Standing reconciliation of sends against copies actually present in \Sent.
 *
 * Post-condition reporting on each tool only covers sends the agent was
 * present for. A mailbox that silently stops filing copies emits nothing at
 * all — that no-event blind spot is what let four days pass before an operator
 * noticed by hand (Task 1822).
 *
 * The copy status comes from reading \Sent, not from the ledger's own recorded
 * outcome. Trusting the recorded flag would only replay what the tool already
 * said; re-reading the folder is what makes this independent evidence, and it
 * is the only way a copy that was filed and later removed shows up.
 *
 * Presence is tested per Message-ID, never by comparing bulk counts. \Sent
 * holds everything the mailbox owner sends from any client, so a total count
 * is dominated by messages this plugin never sent: a mailbox filing none of
 * our sends still reads as healthy the moment its owner sends a few from their
 * phone. Bulk comparison would report clean on precisely the incident this
 * task exists to catch.
