+`triage` is the pathology checklist of the SUMMARY of `<file_prefix>_report.txt`, built from the same result, so
+the two always agree: one entry per condition the report lists (twinning, pseudo-symmetry, multiple lattices,
+ice and powder rings, anisotropy, completeness, sweep gaps, supercell, overloads, ...), plus one for every
+other warning that fired (e.g. `SCALING_NOT_CONVERGED`). Each has the report's label and words, the
+`PATHOLOGY_FLAGS` codes it stands for and the warnings behind it, and a `severity`: `ok` - looked for and not
+found; `attention` - its warning fired; `serious` - nothing usable came out (no lattice, or a merge without
+signal: the report's verdict FAILED or UNUSABLE); `not_measured` - not looked for on this run. A rotation run
+fills it when it is over; a serial one at each provisional merge and at the end. The serial merge has no
+pre-scan and runs no twinning, pseudo-translation or anisotropy analysis, so on serial data those are
+`not_measured`. The "Rugnux live" tab lists the conditions that fired first, in orange or red, then the green
+ones, with the report's warnings on hover, and names the unmeasured ones in one line.

 ### Serial collections (experimental)
 
 Live processing of serial collections is **experimental**. With rugnux live mode on, a serial
