      summary: Create Reminder
      description: 'Schedule a reminder to revisit a post at a future time.


        Two ways to express the time: ``duration`` (a key from

        ``DURATION_MAP`` — "1d", "1w", etc., resolved server-side) OR

        ``remind_at`` (explicit UTC datetime). Exactly one of the two

        is required (schema validator enforces). Naive datetimes are

        promoted to UTC; past timestamps reject with 400

        ``INVALID_INPUT``.


        Upsert semantics: re-posting for the same ``post_id`` updates

        the pending reminder rather than creating a duplicate (a

        ``sent_at`` already-fired reminder is treated as gone). 404

        ``NOT_FOUND`` if the post is missing or soft-deleted.


        Auth required. A background sweeper (``reminders_worker``)

        fires the actual notification when ``remind_at <= now``.


        **Idempotency:** safe to retry with an ``Idempotency-Key`` header.

        Combined with the upsert semantics above, a client can safely

        retry on a network blip without risk of a duplicate row or a

        skipped schedule. See ``Integration → Idempotency`` in /llms.txt.'

        Filters out reminders whose ``sent_at`` is non-null — once a

        is captured by the resulting notification, not by the reminder

        row). Ordered by ``remind_at`` ascending so the next-due

        presents a single response shape rather than leaking whether

        fired the notification — there''s no rollback at this layer.
