+ *
+ * Three columns are sealed: the day-log note, the sensitive-category envelope
+ * and a custom symptom's label. A disaster-recovery file carries them as the
+ * stored ciphertext, which the same instance's key reads back. A portable file
+ * carries them readable (`note`, `sensitive`, `label`), and the restore seals
+ * them under the receiving host's key, because a portable file exists to be
+ * moved, and ciphertext from one host is noise on another.
+ *
+ * Until v1.40 the portable file carried the ciphertext too, so a note restored
+ * onto a host with a different key was unreadable for good. Such a file is
+ * still accepted: every ciphertext value in it is opened with this host's keys
+ * before it is written, and one that does not open is kept out of the row and
+ * named in the skip report (`cycleCiphertext`), never written back as
+ * ciphertext nobody can read. The same check covers a disaster-recovery file,
+ * which is why `RESTORE_SELF_VERIFIED_SECTIONS` lets these sections past the
+ * restore's key preflight.
