483-537: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winMake the restore of
s_dynamicsScorefailure-safe.This test mutates the suite-wide
s_dynamicsScore: it runs an undoable command, then relies on the finalundoRedo(true, nullptr)at Line 536 to restore the original state.ASSERT_TRUEat Line 504 returns from the test function on failure, so the restore never runs. Later tests in the same suite (MirrorEdit_OtherRepeatSegment_CopiesPoint,MirrorEdit_MeasureRepeat_CopiesPoint,Update_RepeatStructureChange_ForcesFullReprocessing) then read a mutated score and can fail for an unrelated reason. Restore the score in a scope guard, or move the undo-stack test to a score loaded per test.♻️ Proposed restore guard

Inline comments:
In `@src/engraving/automation/automationtypes.h`:
- Around line 73-79: Update the AutomationType enum declaration so Volume and
Pan retain their previously persisted numeric values, assigning explicit stable
values to all entries as needed. Ensure CURRENT_AUTOMATION_TYPE serialization
through Val(type) and toEnum<AutomationType>() remains backward-compatible, or
provide the required migration for notation/automation/currentType.
In `@src/engraving/automation/internal/scoreautomationcontroller.cpp`:
- Around line 235-295: Update classifyChanges and update(const ScoreChanges&) so
repeatStructure is either consumed when building the update request or removed
entirely; ensure the classification remains order-independent by preventing the
early loop break from skipping later repeat-related element types such as VOLTA,
MARKER, or JUMP.
- Around line 1279-1288: Update setTempoPoint so generated tempo points do not
overwrite an existing authored point at the same tick in ctx.tempoCurve;
preserve the authored value and generated=false state, while retaining the
current generated-point behavior when no authored point exists. Ensure
mirrorAuthoredPointsToRepeats can still identify and propagate the user-authored
point.
In `@src/engraving/dom/dynamic.cpp`:
- Line 181: Update the tempo ratio calculation to pass tick() directly to
multipliedTempo instead of calling segment()->tick(), preserving zero-tick
behavior for palette dynamics without a segment.
In `@src/engraving/dom/score.cpp`:
- Around line 3536-3545: Update Score::tempo() to resolve utick using an
explicit repeat mode and a non-mutating repeat-list read, avoiding repeatList()
and any call to undoRemoveStaleTieJumpPoints() during tempo lookup. Preserve the
existing tempoTimeline().tempo(utick) result and leave multipliedTempo()
unchanged.
In `@src/engraving/editing/editautomationpoints.cpp`:
- Around line 127-131: Extend the existing assertion in flip() to also validate
m_controller->automationData() before accessing its curve, and return when that
data is null. Preserve the current guard behavior and use the validated
automation data for the subsequent curve lookup.
In `@src/engraving/editing/editmeasures.cpp`:
- Line 397: After the measure-length update and the existing
Score::updateTicksAndTimeSigMap() call, explicitly invalidate the score’s
RepeatList metadata so later InsertTime operations rebuild repeat-segment
boundaries from the new measure lengths.
In `@src/engraving/playback/renderingcontext.h`:
- Line 76: Use unrolled universal ticks for all tempo lookups: update
Score::multipliedTempo in src/engraving/playback/renderingcontext.h lines 76-76
to use chordPosTickWithOffset; update
src/engraving/playback/playbackeventsrenderer.cpp lines 159-159 and 230-230 to
use positionTickWithOffset and measureStartTick + ticksPositionOffset,
respectively.
In `@src/engraving/tests/split_data/split06-ref.mscx`:
- Around line 219-220: Confirm the source change that regenerated the slur
endpoints and ensure each endpoint resolves to a serialized element: in
src/engraving/tests/split_data/split06-ref.mscx lines 219-220, add the missing
l_l element or correct endElement to the valid endpoint; in
src/engraving/tests/join_data/join06-ref.mscx line 201, verify whether c_c
should replace T_T; and in src/engraving/tests/join_data/join10-ref.mscx line
292, verify whether h_h should replace S_S. Update the source or regenerated
fixtures so tempo automation and edit-path map changes do not unintentionally
move slur endpoints.
In `@src/importexport/midi/internal/midiimport/importmidi_tempo.cpp`:
- Around line 71-111: The setTempoToScore function performs the segment lookup
too early, causing skipped tempo events to create empty segments. Move
getChordRestOrTimeTickSegment after all early-return checks that do not require
the segment, including existing tempo and default-tempo checks, then use the
resulting segment for annotation inspection and tempo creation.
In `@src/importexport/musicxml/internal/import/importmusicxmlpass2.cpp`:
- Around line 2701-2704: Update the tempo-annotation scan around the segment
annotations so it does not return after the first TempoText; continue checking
all tempo annotations, return false immediately when any tempo differs from
Constants::DEFAULT_TEMPO, and return true only after the full scan finds no
non-default tempo.
In `@src/importexport/ove/internal/importove.cpp`:
- Around line 973-988: Change the adjacent lastTempo state used by the
tempo-import loop to double, and compare tempo values with the existing
RealIsEqual helper instead of integer equality. Preserve fractional tempos such
as 120.5 and prevent duplicate or skipped TempoText creation while leaving the
shown tempo insertion logic unchanged.
In
`@src/notationscene/qml/MuseScore/NotationScene/notationautomationcontroller.cpp`:
- Around line 216-224: Update the guard in createPolylinesForSystem to compare
staffIdx with system->firstVisibleStaff(), matching the system-specific
visibility used by the surrounding traversal. Remove the now-unused
firstVisibleStaffIdx helper and apply the same correction to the additional
affected guard.

The test performs 100,001 extra normalize/denormalize round trips, each with its own
EXPECT_NEAR.normalizeTempoanddenormalizeTempoare a single divide and a single multiply, so the failure modes are magnitude-dependent, not step-dependent.

fixAnacrusisTempoassumes the next measure is in the same repeat pass.The function derives
nextMeasureTickby adding the anacrusis measure's owntickOffset. If the anacrusis measure is the last measure of its repeat segment, the next measure belongs to a different pass and carries a different offset, so the lookup reads an unrelated utick. An anacrusis is normally the first measure of a section, so the case is rare, but a section break directly after a pickup measure can produce it.

Skip the default initial tempo marker.
When the first tm entry equals Constants::DEFAULT_TEMPO, do not create an invisible TempoText. This matches the OVE and MIDI importers and avoids a redundant 120 BPM marker.

In `@src/engraving/rw/read114/read114.cpp` around lines 3095 - 3129, Update the
tempo-marker creation loop over tm to skip the first entry when its value equals
Constants::DEFAULT_TEMPO, before creating or adding a TempoText. Preserve
processing of all other tempo entries and the existing matching-tempo checks.
