set: two leftovers from the rehearsal stopped their tracks compiling

Both were mid-thoughts from tonight, and each killed EVERY dN in its block
because a .tidal track is one do block.

liquid_nite:46 had '$ midiOn "^58" (iter 4 . )' -- a dangling composition
operator, so the section typed as a function-to-function instead of a
Pattern ValueMap endomorphism. Dot dropped, keeping both lines he added
tonight (the new ^58 iter and the ^90 ply he uncommented). PLN authorised
this one after closing the editor.

piment_bresilien:96 had 'once $ "90s_synatm:10"', the line he used to
audition the sample whose missing bank was tonight's d9 fix. 'once' is not in
scope in this BootTidal. Commented rather than deleted, with the reason
inline, because the audition itself is worth keeping.

Proof: xargs the 17 paths from armada/setlist_thu24.txt into
silent-eval --seeded -> 'OK - every declared orbit emits events', 17/17.
The earlier 15-track run that found the second one was reading backlog.md's
list, not the setlist: passing an unquoted $VAR to a command in zsh does not
word-split, so silent-eval received one argument and fell back to its
default.
