+## 2024-08-07 - SQLite WAL mode configuration optimization
+**Learning:** SQLite의 `PRAGMA journal_mode=WAL`은 데이터베이스 파일 수준에서 유지되는 영구적인 설정이므로, 매 커넥션을 열 때마다 반복해서 실행할 필요가 없습니다. 빈번하게 생성되는 단기 커넥션 환경에서 이 쿼리를 매번 실행하면 불필요한 I/O 오버헤드가 발생합니다.
+**Action:** 스키마를 초기화하는 시점에 `conn.executescript()`를 사용하여 한 번만 실행하도록 변경하여 성능을 최적화합니다.

 ## 2024-05-28 - Avoid O(N^2) Path.resolve() in Batch Processing
 **Learning:** Python's `pathlib.Path.resolve()` is relatively slow because it touches the filesystem to follow symlinks and resolve relative paths. When dealing with a batch operation (e.g., scanning large directories of media files), calculating protected files via `any(target == src.resolve() for src in sources)` on every check leads to massive O(N^2) CPU overhead.
 **Action:** Pre-resolve the entire list of candidate paths once into a `frozenset` at the beginning of the batch process. Pass this resolved set down the call stack so that collision/protection checks become O(1) hash map lookups instead of triggering millions of unnecessary disk access operations.

-## 2026-07-25 - [Cross-platform upload basename normalization]
-**Behavior:** Upload metadata now interprets both forward slashes and backslashes as path separators before extracting a basename.
-**Learning:** On POSIX systems, `pathlib.Path(filename).name` retains backslashes because they are ordinary characters there. That caused inconsistent manifest and converter filenames for Windows-style client paths. The upload itself is still written inside a trusted temporary workspace, and batch archive entry names are generated outputs; this change does not establish a filesystem traversal or archive-entry escape.
-**Prevention:** Normalize client path separators before extracting a basename, retain the existing empty/`.`/`..` fallback, and test the persisted source name and manifest metadata. Treat the normalization as cross-platform consistency and defense in depth, not as evidence of a demonstrated Zip Slip exploit.

 ## 2026-05-28 - [Sentinel Fixes: Temp Files & Injection]
 **Vulnerability:** Predictable Temp Files (CWE-377) and Insecure Default Permissions (CWE-276), plus Command Injection via FFmpeg Filtergraph (CWE-20).
 **Learning:** Python's `Path.with_name` plus a suffix string to make a temp file opens a race condition because it's predictable and the permissions default to system `umask` which might expose secret `0600` data. Additionally, interpolating variables directly into FFmpeg filtergraph strings allows arbitrary filter injection.

 ### Fixed
 - 단일·일괄 대상 크기 입력을 비웠을 때 이전 custom validity와 `aria-invalid` 상태를 즉시 초기화해 현재 필수 입력 상태를 정확히 전달합니다.
-- 업로드 파일명의 경로 구분자를 정규화하여 POSIX에서도 Windows 형식의 클라이언트 경로가 일관된 basename으로 기록되도록 수정했습니다.
