| ## 2024-09-15 - Callback iteration optimization in critical path | ||
| **Learning:** Calling Array.prototype.every() incurs callback invocation overhead on each element, which can impact performance in critical execution paths, even if it doesn't allocate an intermediate array. | ||
| **Action:** Replace .every() with a standard for-loop and early return for O(1) memory and avoiding callback overhead to provide a faster check. |

메모리 복잡도 설명을 수정하세요.
apps/desktop/src/features/score/scoreStorage.ts의 readScorePdf는 response.length에 비례하는 new Uint8Array(len) 출력 버퍼를 생성합니다. 따라서 출력 버퍼를 포함한 전체 메모리는 O(N)입니다. O(1)은 출력 버퍼를 제외한 보조 메모리에만 해당합니다.
.every()도 중간 배열을 생성하지 않으므로, 이 최적화의 이점은 콜백 호출과 별도 변환 순회를 제거하는 데 있습니다. .jules/bolt.md는 최적화 지침을 기록하는 문서이므로, 향후 최적화 판단을 오도하지 않도록 Action 문구를 이 효과에 맞게 수정하세요.

Exact-head acceptance at 0d09c6a224456ae9d417dccf99a63e7a8133128a:
The implementation has become a single-pass validate+convert loop, which is materially different from the PR title/body claim. Array.prototype.every() is O(N) and does not allocate an O(N) intermediate array by itself; the old path was two traversals (every then Uint8Array.from), while the new path is one traversal plus the required O(N) output Uint8Array. Please doctor the title/body so we do not ship an unsupported O(N)→O(1) complexity claim.
There is also a semantic delta that needs an explicit RED before this is considered equivalent: .every() skips holes in sparse arrays, while the indexed loop observes a hole as undefined and rejects it. A sparse Tauri payload is probably not expected, but that is an input-contract decision, not a performance fact. Add a boundary test that fixes the intended sparse-array behavior, plus NaN/Infinity/negative/>255/fractional numeric values so the existing Uint8Array coercion contract is intentionally preserved or deliberately tightened.
For the performance claim, benchmark the actual readScorePdf conversion path on representative PDF byte-array sizes in the same JS runtime, with warm-up/repetitions and p50/p95 plus allocation/GC evidence. Unit-test parity alone is not a performance measurement. If the difference is noise, the one-pass refactor may still be kept for clarity, but the buyer-visible performance claim should be removed.
Please also correct .jules/bolt.md date 2024-09-15 to the actual work date and keep the note factual: callback/two-pass overhead, not fictitious intermediate-array allocation.

Source: Coding guidelines
This lane's performance rationale is incorrect: Array.prototype.every does not allocate an intermediate array. The real opportunity is avoiding a second pass, but this implementation also narrows validation to typeof number and silently lets Uint8Array assignment coerce NaN, Infinity, negative, fractional, and >255 values. Canonical Draft #1190 already owns the same scoreStorage bridge optimization with single-pass copying plus explicit integer 0..255 validation and focused invalid-value regressions, while keeping performance claims behind reproducible measurement. Restore this duplicate branch to protected develop as an ordinary descendant and remove the foreign #1176 formatter delta. No force update, destructive rebase, self-approval, gate weakening, or unsupported performance claim.

상태: inferior duplicate optimization 철회 — canonical score bridge lane으로 승계
이 PR의 원래 성능 설명에는 오류가 있습니다.
Array.prototype.every()자체가 O(N) 중간 배열을 만들지는 않습니다. 실제 비용은 callback/validation pass 뒤Uint8Array.from()이 다시 순회한다는 점입니다.더 중요한 문제는 이 PR의 single-pass 구현이
typeof val === "number"만 검사한다는 것입니다. 그 상태에서Uint8Array대입은NaN,Infinity, 음수, 소수, 255 초과 값을 coercion할 수 있으므로 기존/의도된 IPC byte-domain validation을 약화시킬 수 있습니다.Canonical Draft #1190은 같은
scoreStoragebridge를 이미 소유하며 다음을 더 강하게 보존합니다.0..255byte-domain validationordinary descendant repair
