//| One fixed-width record of every modality's reading at the signal  |
//| bar. It is the single source of truth for three consumers that    |
//| used to be three hand-kept lists: the modalities WRITE it, the    |
//| trade book PERSISTS it (header and row both come from CtxName()), |
//| and the reviewer BUCKETS it. Add a field once, here, and all      |
//| three follow; nothing else spells a column name.                  |
//|                                                                   |
//| CTX_NA marks a reading the modality could not produce. It is      |
//| never zero: a missing Wyckoff read must not look like "phase 0".  |
