 ## Change Log
 
+### CHG-20260627-03
+- Date: 2026-06-27
+- Author: portfolio-hub-dev
+
+#### Change Summary
+- `_PORTFOLIO_NAME_RE` 정규식 완화: 한글(가-힣) + 공백 허용 추가.
+
+#### Intent
+- 포트폴리오 name은 `(owner_user_id, name)` 조회 키로만 쓰이며 wire 식별자가 아니므로 UTF-8 한글이 안전하다. 사용자 가독성 향상을 위해 한글 이름과 공백을 허용한다.
+
+#### Acceptance Criteria Delta
+- No change (기존 AC 그대로 유지)
+
+#### Impacted Area Delta
+- `app/schemas/portfolio.py`: `_PORTFOLIO_NAME_RE` → `^[a-zA-Z0-9가-힣 ._:\-]{1,100}$`, `validate_name` 에러 메시지 갱신.
+- `tests/test_portfolio_uuid.py`: 한글 name 통과(`test_name_validation_accepts_korean`), 기존 ASCII name 통과(`test_name_validation_accepts_ascii_unchanged`), 101자 초과 거부(`test_name_validation_rejects_over_100_chars`) 케이스 추가.
+
+#### Delivery Trace Delta
+- Batches: minor-change (batch-lite 불필요 단일 저위험 변경)
+- Releases: pending
+
+#### Revalidation Impact
+- Reverification Needed: no (기존 AC 충족 범위 확장만이며 거부 규칙 약화 없음 — `!` 등 비허용 문자는 여전히 거부)
+- Existing Implementation Invalidated: no
+- Status Recommendation: keep-implemented
+- Follow-up Action: 없음
