From Enrico's field pass on il-mio-canto-libero (2026-08-22, #590). Stretches of that recording carry a very low-volume guitar, sometimes playing single notes; MW must label every span, so a span whose harmonic content is one faint note gets the same bold chart symbol as a full-band downbeat. That is where the known folds invent chords: the chart prints F#m bars Enrico is unsure of (he would put D at one of them — D and F#m share two of three notes) and one F#7 he cannot hear at all — while never printing the Bm that the reference page resolves its FA#7 into, which reads as a label hung on noise rather than a heard cadence.
The melody stage got its honesty marking in #649 ("melody not read", once per stretch); harmony has no analog. Two directions, not exclusive: the page says where the evidence was thin, and/or a thin span inherits its context instead of asserting novelty. Related: #458 (one-beat spans no harmonic rhythm supports), #602 (the melody precedent), the per-span residual machinery of #543 which already measures something like evidence mass.
