The first insert intent, and the one that introduces fresh object-id minting
into editor-core (delete/move only referenced existing ids). It adds a note to
the selected pitch's event via InsertIdentifiedPitch — a new identified pitch a
diatonic staff step above the event's highest note, so repeated calls build a
rising chord rather than stacking duplicates on one staff position. The
selection stays on the anchor (which survives), and the new note's acoustic
realization is reset to Implicit so it sounds at its written position rather
than inheriting an explicit absolute frequency from the note it stacks above.
Fresh PitchId minting takes the high-water mark over three sources — the
pristine open-time base, the current score (each live or tombstoned), and this
session's op log — because a pitch deleted via DeleteIdentifiedPitch leaves no
trace in the materialized score (the reducer tombstones only its own state), so
reusing its id would make a later insert no-op against a tombstone under
whole-log reduction. Increment is checked; the log scan covers both insert ops.
Adding is refused (PitchSpellingOverridden) when any note in the event carries
an authored spelling override, since the rendered staff order then cannot be
read off the raw pitch positions — resolved-spelling-aware stacking, and the
new-event insert_note_after_selection, are follow-ups.
