The first repeat-structure ink, review-hardened (19 verified findings fixed
pre-commit). Zero golden churn for repeat-free scores; four new goldens for
the ten_measure_with_repeats fixture.
layout-ir: repeats project LayoutContent::Repeat resolved at to_logical
(RepeatPlacement::At/RegionEnd/Unresolved — honest, no origin fallback;
zero-offsets judged by value; bare wall-clock boundaries draw no ink); deps
now from anchor_sites(). Constrained: coinciding measure barlines morph into
precomposed repeatLeft/Right/RightLeft (name-only, exact provenance kept);
standalone signs synthesize under a semantic (site, staff) instance key;
end repeats at the region close draw repeatDots beside a final barline (or
the full sign on continuing staves); start marks there draw nothing;
end-facing signs reserve their left reach via column overhang; time
signatures clear morphed signs; volta brackets = 3 strokes above the top
staff + timeSig digit numerals, kind-independent.
engrave: ENGRAVER_VERSION 3 -> 4; casting classifies barline columns via
is_barline_glyph AND direct Measure source, so standalone signs are never
phantom break candidates or measure records; criterion-6 round-trip covers
the repeat fixture.
render-svg: repeatLeft/Right/RightLeft/Dots outlines + metrics + font subset
regenerated from the SHA-pinned Bravura (fontTools 4.63.0); GlyphClass::Repeat.
