The my/self split was set to 4.50, where her /s/ begins, and came back
out of the build at 4.715 — back inside the fricative, the exact place
it was moved away from. Cause: only `times` pins were exempt from the
boundary snapper. A syllable cut is just as measured, and the snapper
was free to drag it up to 250 ms.

Both kinds of measured boundary are now authoritative. Verified: my
3.890–4.500, self 4.500–5.235, against a fricative that starts at 4.50.

This is the third time today a correction has been silently undone
downstream of itself — first the notes that kept an aligner's stale
pitch after being repinned, then the pins the snapper dragged, now the
splits. Worth remembering the shape of it: a fix that lands upstream of
an automatic correction has to be marked as intentional, or the
automation treats it as noise.
