⚡ Bolt: Optimize dict.setdefault usage to prevent memory allocation overhead

 **Vulnerability:** User-controlled input in file names and asset metadata was rendered without proper sanitization, allowing execution of arbitrary JavaScript (e.g. `<img src=x onerror=alert(1)>`).
 **Learning:** React escapes text children by default, but relying on this is not enough if variables are passed to components that might render them unsafely, or if scanning tools mandate explicit sanitization functions for user-provided data.
 **Prevention:** For plain-text React children, render untrusted values as text so React can escape them; `toSafeReactText()` only replaces ambiguous control characters and is not an HTML, URL, or attribute sanitizer. Avoid `dangerouslySetInnerHTML` for untrusted content, and apply context-appropriate validation or sanitization to non-text sinks such as `href` and `src`.

-## 2026-07-15 - Prevent URL-Encoded Path Traversal in Email Import
-**Vulnerability:** The `_safe_upload_filename` in `email_import_service.py` checked for path traversals (like `..`) without unquoting the filename first. This allowed an attacker to bypass the validation by URL-encoding or doubly URL-encoding the payload (e.g., `%2e%2e%2fupload` or `%252e%252e%252fupload`).
-**Learning:** Checking for traversal sequences on raw filenames is insufficient if the input path can contain URL-encoded payloads. The check could be bypassed since it happens before decoding, yet the application or storage mechanism may later decode and use the dangerous payload.
-**Prevention:** Always recursively decode `urllib.parse.unquote()` on raw input paths before validating, splitting, or extracting filenames to ensure doubly URL-encoded payloads are correctly decoded and caught, with a bounded loop to avoid DoS.
-
-## 2026-07-22 - Prevent Path Traversal via Backslashes
-**Vulnerability:** The `_safe_upload_filename` in `email_import_service.py` checked for path traversals (like `..`) but did not convert backslashes (`\`) to forward slashes (`/`), meaning that Windows-style path traversal attacks (like `..\..\upload` or encoded versions) could bypass the check.
-**Learning:** Checking for traversal sequences using `pathlib.Path.name` may leave the result vulnerable if the input path can contain Windows-style path separators but the program interprets it dynamically or decodes payloads using backslashes.
-**Prevention:** Always convert backslashes to forward slashes before parsing filenames.
-
-## 2026-07-29 - Prevent SSRF via Local/Internal Domains
-**Vulnerability:** The URL validation logic correctly blocked non-global IP addresses and `localhost`, but failed to block internal domain extensions such as `.internal` or `.local` (or exact matches for `internal`). This could allow attackers to bypass SSRF protections by resolving these internal top-level domains.
-**Learning:** Checking for `localhost` alone is insufficient to prevent SSRF against internal network resources, as modern environments and protocols utilize `.internal` and `.local` domains for internal routing.
-**Prevention:** Always explicitly check and block domains matching `.internal`, `.local`, or `internal` (alongside `localhost`) when validating URLs for global reachability to prevent SSRF bypasses.

 ## [Unreleased]
-### 보안 패치 (CodeQL extended current-head)
-
-- CodeQL `extended` 기본 설정이 current `develop`에서 확인한 Critical 8건·High 21건·Medium 1건을 코드 경계에서 제거합니다. 서버 요청은 검증된 loopback/HTTPS origin, 동일 OIDC issuer origin, 허용 API 경로·쿼리만 재구성하고 redirect를 자동 추종하지 않으며, 공개 IPv6 authority를 보존합니다. UI smoke는 고정 Node/Next 실행 파일과 인자, localhost:3001 allowlist, private `mkdtemp` artifact 디렉터리 및 containment 검사만 사용합니다.
-- OIDC token endpoint는 운영 환경에서 서버 전용 `OIDC_ALLOWED_HOSTS` 정확 호스트 allowlist를 필수로 적용합니다. hostname의 모든 DNS 결과가 공인 주소인지 검증한 뒤 해당 주소 집합을 native HTTP(S) 연결의 `lookup`에 고정하고, 원래 issuer hostname은 Host/TLS SNI로 유지해 사설 주소 해석과 DNS rebinding 사이의 TOCTOU를 차단합니다. 실패 로그는 입력 URL·token 대신 고정된 configuration/DNS·transport/response/backend-verification reason code만 남깁니다.
-- Trivy 2026-07-26 DB에서 새로 확인된 Next.js High 4건·Medium 5건(`CVE-2026-64641`–`CVE-2026-64649`)과 PostCSS High 1건(`GHSA-r28c-9q8g-f849`)을 제거하기 위해 Next.js/`eslint-config-next`를 `16.2.11`, PostCSS를 `8.5.18`로 갱신했습니다. 두 버전은 각 취약점의 최초 수정 버전이며 저장소의 release-age 정책을 우회하지 않습니다.
-- `pnpm audit`가 개발 도구 체인에서 추가 탐지한 `brace-expansion <=5.0.7` High DoS(`GHSA-mh99-v99m-4gvg`)는 `5.0.8` 전역 override로 제거했습니다. CommonJS default export를 기대하는 legacy `minimatch 3.1.5`에는 `expand` named export도 수용하는 최소 pnpm 패치를 적용해 ESLint/glob 동작을 보존합니다.
-- root·frontend Docker build의 frozen install 계층이 pnpm manifest와 함께 `frontend/patches`를 먼저 복사하도록 수정해, 이미지 검증에서도 lockfile의 patched dependency를 동일하게 재현합니다.
-- Scorecard SARIF normalizer는 고정 workspace artifact로 정규화되는 `./scorecard-results.sarif`와 절대 경로를 동일하게 허용하면서 symlink·workspace 이탈은 계속 거부합니다. 도구 실행 실패 API는 CR/LF·제어 문자를 escape하고 500자로 제한하며, 로그에는 raw 도구 코드·예외 text 대신 SHA-256 기반 코드·traceback 상관 식별자만 기록합니다.
-- 백엔드 origin 보안 경계를 `frontend/src/lib/backend-url.ts`의 단일 생성기로 통합해 API proxy·session·OIDC callback이 같은 검증을 사용합니다. UI smoke의 새 `NARUON_FULL_PRODUCT_SCREENSHOT_PROFILE` 이름은 실제 selector 의미를 드러내며, 기존 `..._SCREENSHOT_DIR`은 호환 alias로 계속 지원합니다.
-- PR governance의 CodeRabbit issue-summary 분류는 실제 pre-merge 실패·blocking finding·actionable comment 신호만 차단하고, current-head SHA가 포함된 `Review limit reached` 같은 운영 quota 안내는 소스 결함으로 오분류하지 않습니다. check-run 결론과 inline review comment 검사는 그대로 유지됩니다.
-- 제품 이벤트 ID의 `Math.random()` fallback을 Web Crypto 기반 UUID/128-bit 난수로 교체하고, 개인 메일 smoke·live HTTP·Scorecard SARIF 경로에 home/workspace containment, symlink·크기·ZIP entry 제한, loopback endpoint allowlist를 적용했습니다. 도구 실패 로그는 사용자 입력 대신 고정 event와 예외 유형만 기록합니다.
-- 검증: 백엔드 `1560 passed, 32 skipped`(`PYTHONWARNINGS=error`), 프런트 `385 passed`, ESLint, Ruff, TypeScript, Next.js production build, 변경 Python 대상 Bandit Medium 이상 검사, Trivy Medium 이상 검사와 정확한 hash/lock 입력의 OSV 검사가 통과했습니다. GitHub hosted CodeQL/SARIF current-head 결과는 PR checks에서 별도로 확인합니다.

 ### 마이그레이션 정합성 (Alembic single-head 복구)
 
 - Alembic 마이그레이션 그래프의 head가 둘로 갈라져(`0011_email_read_state` — `email_records.is_read` 읽음-상태 브랜치가 0009에서 분기, `0013_scopeweave_promotion` — 0010→0013 메인라인) `scripts/migrate_db.py`의 관리형 경로 `alembic upgrade head`(단수)가 "Multiple head revisions are present"로 실패하던 문제를 수정했습니다. 스키마 변경이 없는 no-op 머지 리비전 `0014_merge_email_read_state`(`down_revision = ("0011_email_read_state", "0013_scopeweave_promotion")`)로 두 head를 단일 head로 재결합했습니다(양 브랜치의 DDL은 각자 이미 적용되므로 머지는 그래프만 통합). 재발 방지 가드로 `tests/test_alembic_migrations.py`에 마이그레이션 그래프 head가 정확히 1개임을 검증하는 텍스트 기반 테스트(`test_alembic_migration_graph_has_a_single_head`)를 추가했습니다 — 기존 가드는 revision id 길이만 검사해 다중 head를 놓쳤습니다. 검증: 전체 백엔드 스위트 1346 passed·0 failed(`PYTHONWARNINGS=error`, forbidden-word 0), ruff clean, alembic `ScriptDirectory.get_heads()` == 1.
