Migration 0003_send_log_lines.sql, DDL only: queue id, the line's own time, the line. No reference to send_log, because a message's first lines are logged before the journal milter writes its row and one queue id is several rows. Store methods: InsertSendLogLine; InsertSendLogLineOnce for lines the tailer reads twice after an unclean stop; SendLogLines, which gives a row the lines of its queue id dated from an hour before the row to the queue lifetime after it, so a later message under a reused id is not shown; PruneSendLogLines, which deletes lines whose queue id has no send-log row - the whole of the table's retention. A line is cut to 4096 bytes. Nothing writes or reads the table yet. Checked on Windows: go vet and go test ./internal/store pass, with the schema test pinning the new table, its index and user_version 3. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
