Preservation / succession status

This branch is provenance only; it is not a second GrooveMap max-offset source owner.

The generated if (n.offset > max) rewrite is not semantically equivalent to the former Math.max fold for NaN; its unsupported speedup claims also lack representative Chromium/Electron buyer-path evidence. Canonical #1170 already keeps the indexed scan while preserving Math.max semantics.

The useful review finding from this lane was the missing rendered-geometry regression for an offset beyond the ten-second floor. #1170 already adopted stronger executable evidence: finite/non-finite max-offset semantics plus a 10s→20s note required to render with left: 50% and width: 50%.

Fresh duplicate-test recurrence and repair

After validated zero-delta head 3ebdac0e..., live descendant b32a14f6088d6bd111e2d9dcbdd772e58c967d44 added only apps/desktop/src/features/workspace/GrooveMap.test.tsx (+51/-0). The new test again checks the 10s→20s geometry, but #1170 already owns the same evidence in a stronger focused test alongside maximumNoteOffset() finite/non-finite semantics. Retaining this file here would recreate a second GrooveMap test owner without a unique contract.

Ordinary descendant ed0414a30b2293b93f9324e82c6f5f4042735cf3 uses b32a14f... as parent and restores the exact protected develop tree. The branch ref advanced with force=false; the generated test commit remains ancestry. This lane therefore returns to zero current production/test delta.

Every source movement invalidates predecessor checks/reviews. Fresh exact-head evidence only counts; absent/queued/pending is not GREEN.

PR-0 / close rule

Keep Open / Draft until #1170 or a verified successor preserves the useful geometry evidence, reconciles shared timing admission as appropriate, obtains fresh exact-head repository/security/CodeQL evidence plus qualifying independent non-author approval, and reaches protected ancestry. Only then may this zero-delta provenance lane be closed unmerged.

No force-push, destructive rebase, duplicate GrooveMap source/test, unsupported speedup claim, source-neutral wake commit, blind rerun, synthetic status, gate weakening, predecessor-evidence transfer, or premature Close.

The calculation change appears mergeable, but a targeted test assertion would better protect note placement for longer transcriptions.

notes; keep the existing title and pitch assertions.

Restore the validated preservation tree while retaining the intervening generated commit in ancestry. The reverted delta reintroduced the non-equivalent if(offset > max) loop, removed the note-derived geometry regression, and added an unmeasured performance claim already rejected in favor of canonical #1170.

Retain the fresh generated GrooveMap rewrite and formatter drift in ancestry while restoring the validated preservation tree. Canonical #1170 remains the max-offset owner; this lane keeps only the previously adopted render-geometry evidence and does not take #1176 formatter ownership.

확인했습니다. 테스트 코드만 유지하고 관련 없는 프로덕션 및 테스트 파일 변경 사항은 복원된 상태로 유지됨을 인지했습니다. 작업 종료하겠습니다.

Remove the generated GrooveMap/test delta from the active diff. Canonical #1170 already contains the semantics-preserving max-offset scan and the useful >10s rendered-geometry regression, while #1254 owns shared timing admission. Keep this branch only as ancestry/provenance until verified protected succession satisfies PR-0.
