+# DoriDesignSystem Design Tokens
+
+Sync rules:
+
+- When DoriDesignSystem color or typography tokens change, update this file in the same PR.
+- When changing a color, update **both light and dark** hex values together. The asset catalog stores them as a single colorset with two appearance variants.
+
+## Overview
+
+This file documents the color and typography surface of `DoriDesignSystem` for iOS SwiftUI implementation. It intentionally covers only colors and typography; components, icons, images, spacing, radius, and elevation are outside this document's scope.
+
+Implementation source of truth:
+
+- Colors (semantic): `Resources/Colors.xcassets/Semantic/`
+- Colors (legacy, deprecated): `Resources/Colors.xcassets/Brand/Secondary.colorset` only — pending designer review for a brand-secondary spec.
+- Typography: `Sources/Typography/TypoStyle.swift`, `View+.swift`, `FontProvider+Impl.swift`, and `FontStyle.swift`
+
+Use the YAML front matter as the machine-readable mirror of the current implementation. If the YAML and Swift/assets disagree, fix the source token and this document together instead of guessing.
+
+## Colors
+
+The system is **semantic tokens with built-in dark mode**. Each token resolves to a different hex value in light vs. dark via asset catalog appearance variants — SwiftUI swaps automatically, no runtime branching needed.
+
+Use generated asset accessors instead of raw SwiftUI colors or duplicated hex values. Prefer SwiftUI asset shorthand such as `.foregroundStyle(.textPrimary)` and `.background(.bgPrimary)`. Use `UIAsset.Colors.<token>.color` or `DoriColors.<token>.color` when shorthand doesn't fit (UIKit interop, explicit `Color` value).
+
+| Token | Asset name | Light | Dark | Swift usage |
+| --- | --- | --- | --- | --- |
+| `bgPrimary` | `Semantic/BgPrimary` | `#FDFDFD` | `#111111` | `.background(.bgPrimary)`, `DoriColors.bgPrimary.color` |
+| `bgSecondary` | `Semantic/BgSecondary` | `#F2F4F6` | `#232323` | `.background(.bgSecondary)`, `DoriColors.bgSecondary.color` |
+| `bgScrim` | `Semantic/BgScrim` | `#000000` α 0.4 | `#000000` α 0.6 | `.background(.bgScrim)`, `DoriColors.bgScrim.color` (modal/loading overlay) |
+| `textPrimary` | `Semantic/TextPrimary` | `#111111` | `#FDFDFD` | `.foregroundStyle(.textPrimary)` |
+| `textSecondary` | `Semantic/TextSecondary` | `#6B7684` | `#A0A0A0` | `.foregroundStyle(.textSecondary)` |
+| `textDisabled` | `Semantic/TextDisabled` | `#B0B8C1` | `#5A5A5A` | `.foregroundStyle(.textDisabled)` |
+| `textPlaceholder` | `Semantic/TextPlaceholder` | `#B0B8C1` | `#5A5A5A` | `.foregroundStyle(.textPlaceholder)` |
+| `borderDefault` | `Semantic/BorderDefault` | `#E5E8EB` | `#2E2E2E` | `RoundedRectangle(...).stroke(.borderDefault, lineWidth: 1)` |
+| `borderInput` | `Semantic/BorderInput` | `#B0B8C1` | `#5A5A5A` | `.stroke(.borderInput, lineWidth: 1)` |
+| `brandMain` | `Semantic/BrandMain` | `#20346F` | `#6C8FF0` | `.foregroundStyle(.brandMain)`, `.background(.brandMain)` |
+| `onBrand` | `Semantic/OnBrand` | `#FFFFFF` | `#FFFFFF` | `.foregroundStyle(.onBrand)` — text/icon on top of a brand-colored surface. Stays light in both modes. |
+| `feedbackTextError` | `Semantic/FeedbackTextError` | `#E54848` | `#FF5A5F` | `.foregroundStyle(.feedbackTextError)` |
+
+`textDisabled` and `textPlaceholder` share hex values today but are kept as separate tokens because their roles differ — a future design pass may diverge them.
+
+### Deprecated tokens
+
+`DoriColors.secondary` (light `#6482AD`) remains as the only legacy token. It is still referenced from the transaction-category accent (judori/outdori) because the Figma spec does not yet define a brand-secondary token. The asset stays at `Colors.xcassets/Brand/Secondary.colorset`, the Swift case is emitted with `@available(*, deprecated)`, and every reference produces a compiler warning.
+
+Resolve with the designer: either promote it to a proper semantic token (`brandSecondary` with a defined dark variant) or migrate the remaining call sites to `brandMain` and delete the asset.
+
+The original primitive palette (`main`, `doriWhite`, `doriBlack`, `grey50` ~ `grey900`) has been fully removed in PR2. Call sites were rewritten to the semantic tokens above; the colorset files no longer exist.
+
+## Typography
+
+Use `.pretendard(_:)` on SwiftUI views. Prefer semantic tokens when a matching role exists:
+
+```swift
+Text("도리")
+  .pretendard(.headline(.h1))
+
+Text("내용")
+  .pretendard(.body(.r3))
+```
+
+Use primitive `TypoToken` values only when no semantic token fits:
+
+```swift
+Text("Label")
+  .pretendard(.bold(.b15))
+```
+
+`PretendardProvider` maps token weights to these bundled font names:
+
+| Weight | Font name | Numeric weight |
+| --- | --- | --- |
+| regular | `Pretendard-Regular` | 400 |
+| medium | `Pretendard-Medium` | 500 |
+| semiBold | `Pretendard-SemiBold` | 600 |
+| bold | `Pretendard-Bold` | 700 |
+
+Current line-height rule is implemented in `FontStyle`: `lineHeight = 2 * fontSize - 6`, and SwiftUI receives `lineSpacing = lineHeight - fontSize`. The front-matter typography dimensions use `px` for DESIGN.md compatibility, but they mirror the iOS `CGFloat` point sizes used by SwiftUI.
+
+| Semantic token | Swift usage | Primitive token | Font name | Size | Line height |
+| --- | --- | --- | --- | --- | --- |
+| `headline.h1` | `.pretendard(.headline(.h1))` | `.bold(.b16)` | `Pretendard-Bold` | 16 | 26 |
+| `title.t1` | `.pretendard(.title(.t1))` | `.medium(.m16)` | `Pretendard-Medium` | 16 | 26 |

+
+### Non-Pretendard fonts
+
+The Pretendard token system covers app-wide text. For brand or display surfaces that need a different face, add a dedicated `View` modifier per face instead of stretching the Pretendard tokens. These are intentional exceptions, not part of the semantic token system.
+
+The current example is the splash/intro logo, which uses `SDSamliphopangcheTTFBasic` via `.hopangche(size:)`:
+
+```swift
+Text("도리")
+  .hopangche(size: 55)
+```
+
+When introducing another non-Pretendard face, follow the same shape:
+
+1. Add a `FontProvider` conformer for the face (see `SamlipHopangProvider` in `FontProvider+Impl.swift`).
+2. Bundle the font file and register it through `FontManager`.
+3. Expose a single `View` extension named after the face (mirroring `.hopangche(size:)`).
+4. Document the intended scope here so the exception stays visible.
+
+## Do's and Don'ts
+
+- Do reach for semantic tokens (`bgPrimary`, `textSecondary`, `borderInput`, `brandMain`, ...) for all new code. Light/dark switching is automatic via the asset catalog.
+- Do use SwiftUI shorthand (`.foregroundStyle(.textPrimary)`, `.background(.bgPrimary)`, `.stroke(.borderInput, lineWidth: 1)`) first; fall back to `UIAsset.Colors.<token>.color` / `DoriColors.<token>.color` only when shorthand doesn't fit.
+- Do use `bgScrim` for modal and loading-overlay backdrops instead of `Color.black.opacity(...)`.
+- Do use `onBrand` for text or icons sitting on top of a brand-colored fill — it intentionally stays light in both light and dark modes.
+- Do use `.pretendard(.body(.r3))` and other `TypoSemantic` values before reaching for primitive `TypoToken` values.
+- Do keep this document synchronized with `Colors.xcassets` and `Sources/Typography` in the same PR as any token change, and update both light and dark hex values together.
+- Don't use `DoriColors.secondary` in new code. It is deprecated and slated for resolution with the designer.
+- Don't introduce raw `Color(...)`, raw hex literals, or `Color.black.opacity(...)` for foregrounds/backgrounds in feature code. Shadow color arguments (`.shadow(color: .black.opacity(0.1), ...)`) and the dark info-toast background in `DoriToastView` are the documented exceptions.
+- Don't set `Font.system(...)`, raw `.custom(...)`, or hardcoded Pretendard names in feature views when `.pretendard(...)` can express the intended token.
+- Don't document or consume spacing, radius, elevation, icons, images, or component-specific styling from this file; those are not currently part of this DESIGN.md scope.

+## Features
+
+- {{FEATURE_1}}
+- {{FEATURE_2}}
+- {{FEATURE_3}}
+
+## Tech Stack
+
+- **Language / Platform** — Swift 6, iOS 17.6+, Xcode 26.2
+- **Architecture** — TCA (The Composable Architecture)
+- **Project Generation** — Tuist (mise 로 툴체인 버전 고정)
+- **Auth** — Kakao SDK + Security framework 기반 토큰 저장
+- **Network** — 자체 네트워크 레이어 + 인증 인터셉터
+
+선택 근거는 [`docs/core/tech-stack.md`](docs/core/tech-stack.md) 에 정리되어 있다.
+
+## Architecture
+
+TCA 기반 5계층 구조다. View → Feature(Reducer) → Client 경계 → Platform / Infra 순으로 흐르고, 인증은 UI·저장소·네트워크가 하나의 흐름으로 연결된다.
+
+```
+AppFeature
+  ├── Splash     # 인증 진입 판단
+  ├── Intro      # 로그인
+  └── MainTab    # 메인 기능 조합
+```
+
+시스템의 큰 그림, 경계, 변경 비용이 큰 결정은 [`ARCHITECTURE.md`](ARCHITECTURE.md) 에 둔다. README 는 진입점일 뿐이며, 구조 설명의 진실 출처는 그쪽이다.
+
+## Project Structure
+
+```
+Projects/
+  App/        앱 부트스트랩, dependency 조합, 루트 route 소유
+  Feature/    사용자 흐름, 화면 상태
+  Core/       도메인 모델, 디자인 시스템, 공통 의존성 키
+  Platform/   Kakao SDK, Keychain, iOS 런타임 어댑터
+  Infra/      네트워크 서비스, 인증 인터셉터, 로깅
+```
+
+각 계층의 책임과 경계 규칙은 [`docs/core/directory-structure.md`](docs/core/directory-structure.md).
+
+## Documentation
+
+이 저장소는 README 를 가볍게 두는 대신, 오래 가는 규칙을 주제별 문서로 분리해 관리한다. 아래 트리는 "현재 이 프로젝트가 실제로 지키고 있는 규칙" 의 전부다.
+
+### Architecture & Core Rules
+- [`ARCHITECTURE.md`](ARCHITECTURE.md) — 시스템 모양, 모듈 경계, 변경 비용이 큰 결정

-# Project Constitution
-
-이 문서는 Dori-iOS의 헌법이다. 구현 세부와 예시보다 오래 유지되어야 하는 규칙만 적는다. 문서와 코드가 충돌하면, 문서를 코드에 맞게 줄이거나 고친다.
-
-## 1. 문서는 구조만 설명한다
-
-- 변수명, 세부 상태, 구체 액션명 같은 휘발성 정보는 문서화하지 않는다.
-- 문서는 바뀌기 어려운 경계, 책임, 금지 규칙만 다룬다.
-- 낡은 문서를 유지하느니 삭제하거나 참고 자료로 격하한다.
-
-## 2. 상태 변화는 Reducer가 소유한다
-
-- 화면 상태의 소스 오브 트루스는 Feature 상태다.
-- View는 상태를 렌더링하고 사용자 의도를 Action으로 보낸다.
-- View가 네트워크, 인증, 저장소 흐름을 직접 결정하지 않는다.
-
-## 3. 화면 전환은 부모가 통제한다
-
-- 루트 라우트는 앱 루트가 소유한다.
-- 탭 내부 전환, push, modal, 인증 종료 같은 흐름은 부모 Feature가 조합한다.
-- Feature 간 직접 참조보다 delegate 또는 부모 중계를 우선한다.
-
-## 4. 외부 세계와의 통신은 경계 밖으로 밀어낸다
-
-- 서버, SDK, Keychain, 시스템 API와의 통신은 Client 또는 Infra/Platform 경계에서 수행한다.
-- Feature는 외부 시스템의 세부 프로토콜을 몰라야 한다.
-- 인증 재시도와 강제 로그아웃 같은 횡단 관심사는 중앙 경계에서 처리한다.
-
-## 5. 모듈 경계를 흐리지 않는다
-
-- `App`은 조합과 부트스트랩을 담당한다.
-- `Feature`는 사용자 흐름과 상태를 담당한다.
-- `Core`는 도메인 모델과 디자인 시스템을 담당한다.
-- `Platform`은 Apple SDK 및 외부 SDK 연동을 담당한다.
-- `Infra`는 네트워크와 인프라 구현을 담당한다.
-
-## 6. 동시성 안전성을 선언으로 드러낸다
-
-- 동시성 경계를 지나는 타입은 가능한 한 `Sendable`을 명시한다.
-- 기본 UI 해석은 메인 액터 규칙을 따른다.
-- `@unchecked Sendable`은 예외적 선택이며, 안전성 설명 없이 도입하지 않는다.
-
-## 7. 테스트는 상태 전이를 검증한다
-
-- 핵심 테스트 대상은 상태 전이, navigation path 변화, dependency 호출 결과다.
-- UI 모양보다 Reducer 행위를 먼저 검증한다.
-- 외부 의존성은 테스트 더블로 바꿀 수 있어야 한다.
-
-## 8. 인증은 중앙 정책으로 다룬다
-
-- 로그인, 토큰 보관, refresh, 강제 로그아웃은 각 화면이 제각각 처리하지 않는다.
-- Splash는 진입 판단, Intro는 로그인 시작, 네트워크 경계는 인증 실패 반응을 담당한다.
-- 인증 관련 결정을 한 곳에서 설명할 수 있어야 한다.
-
-## 9. 구조 변경은 문서부터 고친다
-
-- 루트 흐름
-- 모듈 경계
-- 인증 정책
-- 네트워크 경계
-- 테스트 전략
-
-위 다섯 가지 중 하나를 바꾸면 구현과 함께 문서를 바로 수정한다.

+# Implementation — (2) assertSnapshotPair Helper
+
+> 짝 문서: 같은 경로의 [`PLAN.md`](./PLAN.md)
+> 대상 PR: `feat/47-snapshot-pair` (base `feat/47-dark-mode-support` — PLAN(1) PR #48 merge 후 develop 으로 rebase)
+
+## 1. What
+
+PLAN.md 의 In-scope 를 산출물 중심으로 재기술.
+
+### 신규 파일
+- `Projects/Core/DoriDesignSystem/Tests/Snapshot/Helpers/SnapshotPair.swift` — `assertSnapshotPair` 헬퍼
+- `docs/decision/supportDarkMode/snapshotPair/{PLAN.md, Implementation.md}` — 본 문서 페어
+
+### 수정 파일
+- `docs/frontend/test-strategy.md` — Stable Rules 에 페어 검증 1줄 + 헬퍼 위치 명시
+
+### 산출물 (검증 결과)
+- 로컬 build-for-testing 성공 로그 (DoriDesignSystemTests 컴파일 OK)
+- 헬퍼 smoke TC 의 record 결과 (light/dark 2장 PNG 자동 생성 후 정리)
+- CI green run URL
+
+### Scope 외
+- 기존 4개 TC 마이그레이션 — 별도 PR
+- `DoriTestSupport` 이전 — PLAN(3) 합류 시점
+- `.preferredColorScheme(.light)` 제거
+
+## 2. How
+
+3페이즈 순차.
+
+### Phase A — 헬퍼 작성 (커밋 1)
+
+`SnapshotPair.swift` 신설. 핵심 요점:
+- `@autoclosure` 로 view-builder 한 번만 평가 후 두 trait 으로 재사용
+- `@MainActor` 로 UIKit Trait 접근 안전성 보장
+- `named: "light"` / `named: "dark"` 으로 baseline 파일명 충돌 방지
+- 모든 source location 인자 (`fileID`, `file`, `testName`, `line`, `column`) 전달하여 실패 메시지가 호출자 함수로 안내
+
+### Phase B — 로컬 smoke 검증 (no commit)
+
+1. `tuist install && tuist generate --no-open`
+2. `xcodebuild build-for-testing -workspace Dori-iOS.xcworkspace -scheme DoriDesignSystem -destination 'id=<iPhone 16 UDID>'` 로 컴파일 확인
+3. 임시 TC 1개 추가 후 record/replay:
+   ```swift
+   func test_pairHelper_smoke() {
+     assertSnapshotPair(of: PrimaryButton(title: "smoke").padding(16).frame(width: 200))
+   }
+   ```
+   - 1회차: "No reference" 로 PNG 2장 자동 기록
+   - 2회차: exit 0
+4. 검증 완료 후 임시 함수 + 생성 PNG 삭제. **커밋에 포함하지 않는다.**
+
+### Phase C — 문서 + push (커밋 2)
+
+`docs/frontend/test-strategy.md` Stable Rules 에 1줄, PLAN/Implementation 문서 같은 커밋. push.
+
+#### Hook 루프
+
+```bash
+git push origin feat/47-snapshot-pair
+RUN_ID=$(gh run list --branch feat/47-snapshot-pair --limit 1 --json databaseId --jq '.[0].databaseId')
+gh run watch "$RUN_ID" --exit-status
+```
+
+build/test green 이면 done. fail 분류는 PLAN(1) Implementation 의 표 그대로.
+
+## 3. When
+
+- **순차 의존**: A → B → C
+- **smoke 결과는 커밋 외**: 임시 TC/PNG 가 PR 에 새지 않도록 검증 직후 정리
+- **기존 baseline 비건드림**: 헬퍼는 새 TC 만 쓰기 때문에 기존 16장 PNG 는 변경 0. 이 분리가 PR review 의 핵심 안전선
+- **base branch**: PLAN(1) 의 swift-snapshot-testing 의존성에 의존하므로 PR #48 머지 전까진 base 가 `feat/47-dark-mode-support`. PR #48 머지 후 develop 으로 rebase
+
+## 4. 종료기준 (Definition of Done)
+
+- [ ] `Projects/Core/DoriDesignSystem/Tests/Snapshot/Helpers/SnapshotPair.swift` 생성, 빌드 통과
+- [ ] 로컬 smoke TC 로 light/dark PNG 2장 자동 기록 확인 (검증 후 삭제)
+- [ ] `docs/frontend/test-strategy.md` 에 헬퍼 규칙 1줄 명시
+- [ ] PR CI 의 build · test step green
+- [ ] 기존 4개 TC 의 baseline PNG 파일명/내용 변경 0건
+- [ ] 본 Implementation.md "검증 기록" 에 CI URL 첨부

+# Dark Mode Validation — (2) assertSnapshotPair Helper
+
+## Context
+
+다크모드 검증 자동화의 3단계 중 2단계.
+- (1) Asset Lint — 완료 (`../validateDarkMode/PLAN.md`, PR #48)
+- (2) **`assertSnapshotPair` 헬퍼** — 본 PLAN
+- (3) Feature 모듈 카탈로그 스냅샷 페어 — 별도 PLAN (`../testingDarkMode/PLAN.md`)
+
+`DoriDesignSystem/Tests/Snapshot/*` 의 4개 TC 가 light/dark 두 함수로 분리돼 있다.
+
+```swift
+func test_enabled_light() {
+  assertSnapshot(
+    of: host { PrimaryButton(title: "저장") },
+    as: .image(layout: .sizeThatFits, traits: UITraitCollection(userInterfaceStyle: .light))
+  )
+}
+
+func test_enabled_dark() {
+  assertSnapshot(
+    of: host { PrimaryButton(title: "저장") },
+    as: .image(layout: .sizeThatFits, traits: UITraitCollection(userInterfaceStyle: .dark))
+  )
+}
+```
+
+PLAN(3) 카탈로그가 같은 패턴을 그대로 늘리면 ~106장이 1개 화면당 두 함수 × view-builder 중복으로 확산된다. 한쪽만 추가하고 다른 쪽을 잊는 사각지대도 생긴다.
+
+이 PLAN 은 **"light/dark 페어 보장"** 을 한 호출에 강제하는 얇은 헬퍼만 도입한다. 기존 4개 TC 의 마이그레이션과 PLAN(3) 의 신규 카탈로그 작성은 별도 작업.
+
+## Scope
+
+### In scope
+- `assertSnapshotPair` 헬퍼 신설 (`Projects/Core/DoriDesignSystem/Tests/Snapshot/Helpers/SnapshotPair.swift`)
+- `named:` 인자로 light/dark suffix 부여 → baseline 파일명 충돌 방지
+- `docs/frontend/test-strategy.md` 에 페어 검증 규칙 1줄 명문화 → 미래 에이전트가 패턴을 잊지 않게
+
+### Out of scope (별도 작업)
+- 기존 4개 TC (`ColorTokenSnapshotTests`, `PrimaryButtonSnapshotTests`, `DoriCommonAlertSnapshotTests`, `DoriToastViewSnapshotTests`) 의 마이그레이션 — baseline 재기록 비용 별도 PR
+- `DoriTestSupport` 모듈로 헬퍼 이전 — PLAN(3) Phase B 합류 시
+- Feature 카탈로그 작성 — PLAN(3)
+
+## Approach
+
+### A. 헬퍼 시그니처
+
+```swift
+@MainActor
+func assertSnapshotPair<V: View>(
+  of view: @autoclosure () -> V,
+  layout: SwiftUISnapshotLayout = .sizeThatFits,
+  record: Bool? = nil,
+  fileID: StaticString = #fileID,
+  file: StaticString = #filePath,
+  testName: String = #function,
+  line: UInt = #line,
+  column: UInt = #column
+)
+```
+
+내부적으로 `assertSnapshot(of:as:named:...)` 을 두 번 호출 — `named: "light"` / `named: "dark"`. `testName` 그대로 전달하여 호출자-함수-기반 baseline 디렉토리 규칙 유지.
+
+### B. baseline 파일명 규칙
+
+- 기존 (별도 함수 × 2): `__Snapshots__/PrimaryButtonSnapshotTests/test_enabled_light.1.png`
+- 신규 (페어 헬퍼): `__Snapshots__/<TestClass>/test_enabled.light-<n>.png` (정확한 포맷은 swift-snapshot-testing 1.18+ `named:` 동작)
+
+헬퍼는 새 TC 만 만들면 기존 baseline 과 충돌하지 않음.
+
+### C. 문서화
+
+`docs/frontend/test-strategy.md` 의 Stable Rules 에 1줄 추가:
+
+> 다크모드를 그리는 View 스냅샷은 light/dark 한 쌍으로만 baseline 을 생성한다. 헬퍼는 `Projects/Core/DoriDesignSystem/Tests/Snapshot/Helpers/SnapshotPair.swift` 의 `assertSnapshotPair`.
+
+AGENTS.md Read Order 에 `docs/frontend/test-strategy.md` 가 이미 포함돼 있어 변경 없음.
+

+## Verification
+
+1. **빌드 통과** — `tuist generate && xcodebuild build-for-testing -scheme DoriDesignSystem` 컴파일 OK
+2. **헬퍼 smoke** — 임시 TC 1개로 light/dark PNG 2장 자동 기록 확인 후 정리 (커밋 제외)
+3. **기존 baseline 무손상** — 마이그레이션 안 함. 기존 16장 PNG 파일명/내용 변경 0건

+
+## Out of Scope but Tracked
+
+- 기존 4개 TC 마이그레이션 — 헬퍼 안정성 확인 후 별도 PR. baseline 재기록 + diff 0건 검증 필요.
+- `DoriTestSupport` 이전 — PLAN(3) Phase B 합류 시 모듈로 이동, feature 테스트 import.
+- `.preferredColorScheme(.light)` 제거 — (1)(2)(3) 전부 완료 + 카탈로그 다크 스냅샷 전수 통과 후.

+
+## 1. What
+
+PLAN.md 의 Scope (P0+P1+P2 ≈ 106장) 를 산출물 중심으로 재기술.
+
+### 신규 파일
+- `Tuist/ProjectDescriptionHelpers/DoriTargets.swift` 수정 동반의 — `Projects/Core/DoriTestSupport/Sources/Mocks/Dori+Mock.swift`
+- `Projects/Core/DoriTestSupport/Sources/Mocks/Partner+Mock.swift` 외 도메인 모델별 `+Mock.swift`
+- `Projects/Core/DoriTestSupport/Sources/Clients/*+MockValue.swift` (누락 client 보강 시)
+- 피처별 스냅샷 테스트 파일 약 12개 (`Projects/Feature/{X}/Tests/Snapshot/*SnapshotTests.swift`)
+- 베이스라인 PNG 약 106장 (`Projects/Feature/{X}/Tests/Snapshot/__Snapshots__/{Y}SnapshotTests/{case}.1.png`)
+
+### 수정 파일
+- `Tuist/ProjectDescriptionHelpers/DoriTargets.swift` — `DoriModules.testSupport` 케이스 추가
+- `Projects/Core/Project.swift` — `.doriFramework(DoriModules.testSupport.module, dependencies: [DoriModules.core.module.projectDependency])` target 추가
+- `Projects/Feature/Project.swift` — Onboarding/AddDori/Calendar/MyPage 의 `.doriUnitTests` 4개 신설, History 의 기존 unit test deps 에 `.external(.snapshotTesting)`, `.testSupport` 추가
+- 누락된 client `previewValue`/`mockValue` (Phase A 점검 결과에 따라 결정)
+
+### 산출물 (검증 결과)
+- record 1회차 로그 ("Automatically recorded snapshot" + exit code 1 = snapshot-testing 의 의도된 첫 실행 동작)
+- replay 2회차 로그 (0 fail)
+- 회귀 시나리오 로그 — 의도적 mock 변경 → diff 보고 → 원복
+- CI green run URL — 4개 신설 테스트 타깃 모두 실행
+- `gh pr checks <PR#>` 전체 PASS
+
+### Scope 외 (이 문서에서 다루지 않음)
+- `assertSnapshotPair` 헬퍼 도입 — (2) PLAN 별도
+- `.preferredColorScheme(.light)` 제거 — (1)(2)(3) 완료 후 별도 PR
+- 부모합성 모달/시트 스냅샷 — PLAN.md 에서 "단독" 으로 결정
+- 모든 client mockValue 의 grounds-up 정비 — 본 PLAN 에 필요한 것만 추가
+
+## 2. How
+
+5페이즈 순차. swift-snapshot-testing 의 **record/replay 2단계 특성**을 명시하고 각 페이즈에서 검증.
+
+### Phase A — Prerequisites 확인 (커밋 0건, 검증만)
+
+코드 변경 없이 게이트 통과 확인.
+
+1. validateDarkMode (1) PLAN 머지 여부 확인 — `Brand/Secondary.colorset` 에 dark appearance 존재
+   ```bash
+   cat Projects/Core/DoriDesignSystem/Resources/Colors.xcassets/Brand/Secondary.colorset/Contents.json \
+     | python3 -c 'import sys,json; print(any("dark" in str(a) for a in json.load(sys.stdin)["colors"]))'
+   # → True 면 통과
+   ```
+2. iPhone 16 시뮬레이터 UDID 확인 (DoriDesignSystem 스냅샷과 동일)
+   ```bash
+   xcrun simctl list devices available | grep "iPhone 16 ("
+   ```
+3. TCA Feature client mockValue 정의 여부 grep
+   ```bash
+   grep -rn "previewValue\|mockValue" Projects/Core/DoriCore/Sources/Clients \
+     Projects/Feature/*/Sources/Clients 2>/dev/null
+   ```
+   누락 client 목록을 Phase B 에서 보강할 대상으로 기록.
+
+게이트:
+- (1) 머지 안 됐으면 본 PLAN 시작 금지. brand secondary 의 다크 변색이 baseline 으로 굳으면 검증 가치 0.
+
+### Phase B — DoriTestSupport 모듈 신설 (커밋 1)
+
+`DoriModules` enum 에 케이스 추가 → `Projects/Core/Project.swift` 에 target 추가 → mock factory 작성.
+
+도메인 모델 mock 패턴 (예: `Dori+Mock.swift`):
+```swift
+import DoriCore
+
+public extension Dori {
+  static let mock = Dori(
+    doriId: 100, userId: 1, partnerId: 100,
+    direction: .judori, partnerName: "조카 1",
+    relationship: "가족", eventType: "생일",
+    amount: 50_000, eventDate: "2025-05-01",
+    isVisited: true, memo: "",
+    createdAt: "2026-02-17T09:00:00"
+  )
+
+  static let mockList: [Dori] = (0..<5).map { i in
+    Dori(doriId: 100+i, ..., partnerName: "파트너 \(i)", ...)
+  }
+}
+```
+
+Phase A 에서 식별된 누락 client mockValue 도 같이 보강.
+
+검증:
+```bash
+tuist install && tuist generate --no-open
+xcodebuild build -workspace Dori-iOS.xcworkspace -scheme DoriTestSupport \
+  -destination 'id=<iPhone 16 UDID>' | tail
+```
+
+커밋:
+```bash
+git add Tuist/ProjectDescriptionHelpers/DoriTargets.swift \
+  Projects/Core/Project.swift Projects/Core/DoriTestSupport/
+git commit -m "chore: add DoriTestSupport module with domain mock factories"
+```
+
+### Phase C — 4개 unit test target 신설 (커밋 2)
+
+`Projects/Feature/Project.swift` 에 `.doriUnitTests` 4개 추가, 각 deps 에 `.external(.composableArchitecture)`, `.external(.snapshotTesting)`, `DoriModules.testSupport.module.projectDependency`. History 기존 target 의 deps 에도 동일 추가.
+
+검증 (빈 테스트 클래스라도 컴파일 통과):
+```bash
+tuist generate --no-open
+for scheme in DoriOnboarding DoriAddDori DoriCalendar DoriMyPage DoriHistory; do
+  xcodebuild build -workspace Dori-iOS.xcworkspace -scheme "${scheme}Tests" \
+    -destination 'id=<iPhone 16 UDID>' | tail -3
+done
+```
+
+커밋:
+```bash
+git add Projects/Feature/Project.swift
+git commit -m "chore: scaffold snapshot test targets for 4 feature modules"
+```
+
+### Phase D — 카탈로그 작성 + Record/Replay 루프 (커밋 3~5)
+
+P0 → P1 → P2 각 tier 별로 같은 패턴 반복.
+
+#### D1: P0 — Root view (커밋 3)
+
+1. 6개 TC 파일 작성 (`SplashSnapshotTests`, `IntroSnapshotTests`, `AddDoriRootSnapshotTests`, `CalendarGridSnapshotTests`, `DoriListSnapshotTests`, `MyPageSnapshotTests`)
+2. **Record 1회차** — baseline 없으면 자동 생성 + 모든 TC fail 로 표기 (snapshot-testing 의 의도된 동작):
+   ```bash
+   xcodebuild test -workspace Dori-iOS.xcworkspace -scheme DoriOnboarding \
+     -only-testing:DoriOnboardingTests -destination 'id=<UDID>' 2>&1 | tail
+   # 로그: "No reference was found on disk. Automatically recorded snapshot..."
+   # exit code: 1 (정상)
+   # PNG: __Snapshots__/SplashSnapshotTests/test_splash.1.png 등 자동 생성
+   ```
+3. **Replay 2회차** — 같은 명령 재실행. 이번엔 모든 TC pass 해야 정상:
+   ```bash
+   xcodebuild test -workspace Dori-iOS.xcworkspace -scheme DoriOnboarding \
+     -only-testing:DoriOnboardingTests -destination 'id=<UDID>' 2>&1 | tail
+   # exit code: 0
+   ```
+4. baseline PNG git add + 커밋:
+   ```bash
+   git add Projects/Feature/Onboarding/Tests/Snapshot \
+     Projects/Feature/AddDori/Tests/Snapshot \
+     Projects/Feature/Calendar/Tests/Snapshot \
+     Projects/Feature/History/Tests/Snapshot \
+     Projects/Feature/MyPage/Tests/Snapshot
+   git commit -m "test: P0 dark-mode snapshot baselines (6 TC × light/dark = 12)"
+   ```
+5. **회귀 시나리오** — 정확성 증거. 임의 1건 mock state 약간 변경 → replay → diff 보고 확인 → 원복:
+   ```bash
+   # 예: SplashSnapshotTests 의 mock 메시지 한 글자 변경
+   # 재실행 → fail with diff
+   # 원복 → 재실행 → pass
+   ```
+
+#### D2: P1 — 주요 state 분기 (커밋 4)
+17 TC × 2 = 34장. D1 과 동일 패턴 (record → replay → 커밋 → 회귀 시나리오).
+
+#### D3: P2 — 전체 카탈로그 (커밋 5)
+~30 TC × 2 = ~60장. 동일.
+
+### Phase E — CI 통합 + Hook 루프
+
+`.github/workflows/build.yml` 의 test step 이 신설 4개 scheme 을 자동 픽업하는지 확인. 보통 `xcodebuild test -workspace` 전체 실행이면 추가 작업 없음. 누락 시 `-scheme` 또는 `-only-testing` 옵션 보강.
+
+push & 추적:
+```bash
+git push origin <branch>
+RUN_ID=$(gh run list --branch <branch> --limit 1 --json databaseId --jq '.[0].databaseId')
+gh run watch "$RUN_ID" --exit-status
+WATCH_EXIT=$?
+if [ $WATCH_EXIT -ne 0 ]; then
+  gh run view "$RUN_ID" --log-failed | tail -200
+fi
+gh pr checks <PR#>
+```
+
+#### Fail 분류 & 대응
+
+| 원인 분류 | 예시 | 대응 |
+|---|---|---|
+| **Snapshot baseline 누락 commit** | `__Snapshots__/` 가 git add 안 됐고 CI runner 가 새로 record 시도 → "No reference" fail | 로컬에서 git add 누락 확인 → 재커밋 → push |
+| **시뮬레이터 픽셀 차이** | "Snapshot does not match reference" with sub-pixel diff | CI macOS runner 의 iPhone 16 + Xcode 26.x 매칭 확인. 다른 머신에서 record 됐다면 동일 환경에서 re-record |
+| **테스트 코드 컴파일 실패** | mock factory public 접근 실수, missing import | 로컬 빌드 검증 후 재push |
+| **TCA / strict concurrency 회귀** | Sendable 류 에러 | PR1 의 TCA 1.25.5 bump 이후 발생하면 별건 — 별도 PR 로 처리 |
+| **범위 외** | macOS runner 다운, Xcode `latest-stable` 변경 | 로그 요약 보고 후 대기. 자동 수정 금지 |
+
+루프는 **green 한 번 확인** 으로 종료. snapshot 만 green 이고 build/test 가 fail 인 부분 성공도 fail 로 간주.
+
+## 3. When
+
+- **순차 의존**: A → B → C → D1 → D2 → D3 → E. 각 phase 의 검증 통과가 다음 게이트.
+- **Phase A 의 게이트**: validateDarkMode (1) PLAN 머지 안 됐으면 본 PLAN 시작 금지.
+- **Snapshot-testing 의 record/replay 2단 검증** — 가장 중요한 특성:
+  - **첫 record 의 exit 1 은 정상**. 새 PNG 가 디스크에 떨어졌으면 의도된 동작.
+  - **반드시 replay 2회차 까지 돌려 통과해야** baseline 신뢰 가능. 1회차만 보고 끝나면 깨진 baseline 이 영구 박힐 위험 — 그 baseline 이 어떻게 보이는지 사람 눈이 검토한 적 없음.
+  - replay 2회차 통과 후에도 **회귀 시나리오 (의도적 fail) 1건 확인** 으로 detection 정확성 검증.
+- **각 phase 의 PNG 는 git commit 이후 다음 phase**. 푸시 안 한 채 다음 phase 들어가지 말 것.
+- **Hook 루프**: `gh run watch --exit-status` 가 자체 블록. 사람 timeout 없이 CI 종료까지 기다림.
+- **D1 → D2 → D3 의 cadence**: 한 tier 가 record/replay/회귀 시나리오 3중 검증 통과해야 다음 tier. 한 번에 106장 record 후 일괄 검증은 금지 — 어느 layer 가 깨졌는지 분리 불가.
+
+## 4. 종료기준 (Definition of Done)
+
+다음을 **모두** 만족해야 done.
+
+### 일반 종료기준
+- [ ] Phase A 게이트 통과 — validateDarkMode (1) PLAN 머지 완료, `Brand/Secondary.colorset` 에 dark appearance 존재
+- [ ] `DoriTestSupport` 모듈 빌드 성공, 외부 import 가능
+- [ ] 4개 신설 테스트 타깃 (DoriOnboardingTests, DoriAddDoriTests, DoriCalendarTests, DoriMyPageTests) 컴파일 통과 + 기존 DoriHistoryTests 도 deps 보강 후 통과
+- [ ] P0 12장 baseline PNG 생성 + replay 통과
+- [ ] P1 34장 추가 baseline + replay 통과
+- [ ] P2 ~60장 추가 baseline + replay 통과 (누계 ~106장)
+- [ ] CI 의 `Build App` 워크플로 에서 신설 테스트 타깃 모두 실행 + green
+- [ ] `gh pr checks <PR#>` 전체 PASS
+- [ ] 최종 CI run URL 이 이 문서 "검증 기록" 섹션 에 첨부
+
+### Snapshot-testing 특유 종료기준
+
+- [ ] **Record 단계 증거**: 각 tier 의 첫 실행 로그에서 "Automatically recorded snapshot" 메시지가 모든 신규 TC 에 대해 출력됨 (자동 생성 실패는 file system 권한 / 디스크 가득 등의 이슈)
+- [ ] **Replay 단계 증거**: 각 tier 의 2회차 실행 exit code 0, 0 fail
+- [ ] **PNG 무결성**: 모든 baseline PNG 가 0byte 이상, GitHub PR Files 탭 에서 이미지로 렌더됨 (raw binary 가 아닌)
+- [ ] **회귀 정확성**: 각 tier 마다 의도적 fail 시나리오 1건 — mock state 살짝 변경 → snapshot diff 보고됨 → 원복 후 다시 pass. snapshot-testing 의 detection 이 살아있다는 증거.
+- [ ] **device-pinning 일관성**: CI runner 의 시뮬레이터 디바이스(iPhone 16) + Xcode 26.x 가 로컬 baseline 생성 환경과 일치. 다른 환경에서 baseline 깨지면 그것이 회귀가 아니라 환경 차이임을 분리 보고할 수 있는 가설 기록 남김.
+
+### 검증 기록 (완료 시 채움)
+
+- Phase A 게이트 통과 증거:
+  ```
+  1. Brand/Secondary.colorset has dark variant: True (validateDarkMode (1) 머지 확인됨)
+  2. iPhone 16 simulator: 8040555B-0993-497F-AB25-AA998E428899
+  3. TCA client previewValue 점검 — 9개 중 6개 존재. 누락 3개:
+     - AuthTokenStoreClient (liveValue + testValue 만)
+     - KakaoServerLoginClient (liveValue + testValue 만)
+     - UserNotificationSettingsClient (liveValue + testValue 만)
+     → Phase B 에서 보강
+  ```
+- Phase B DoriTestSupport 빌드 로그: `xcodebuild build -scheme DoriTestSupport ... EXIT 0`
+- Phase C 4개 unit test target 컴파일 로그: 5/5 schemes (Onboarding/AddDori/Calendar/History/MyPage) `** TEST BUILD SUCCEEDED **`
+- Phase D1 (P0) record 로그:
+  ```
+  6 TC × 2 modes = 12 baseline
+  모든 TC: "No reference was found on disk. Automatically recorded snapshot..."
+  PNG 12장 생성 확인: __Snapshots__/{Splash,Intro,AddDoriRoot,CalendarGrid,DoriList,MyPage}SnapshotTests/
+  ```
+- Phase D1 replay 로그:
+  ```
+  FeatureOnboarding: Executed 4 tests, with 0 failures (SplashSnapshotTests 2 + IntroSnapshotTests 2)
+  FeatureAddDori:    Executed 2 tests, with 0 failures
+  FeatureCalendar:   Executed 2 tests, with 0 failures
+  FeatureHistory:    Executed 2 tests, with 0 failures (DoriListSnapshotTests)
+  FeatureMyPage:     Executed 2 tests, with 0 failures
+  → 12/12 PASS
+  ```
+- Phase D1 회귀 시나리오 로그 (fail → 원복 → pass):
+  ```
+  의도적 변경: SplashSnapshotTests/test_splash_light layout .fixed(393,852) → .fixed(320,600)
+  → "Snapshot does not match reference"
+  → "Newly-taken snapshot@(320.0, 600.0) does not match reference@(393.0, 852.0)"
+  → TEST FAILED (detection 살아있음을 증명)
+  원복 후 재실행 → PASS
+  ```
+
+  추가 노트: FeatureHistory 의 사전 Swift Testing 기반 테스트 2개(SearchFeatureTests, EditDoriMemoFieldTests)가 deps 그래프 변경 후 "Restarting after unexpected exit, crash, or test timeout" 으로 죽음. 본 PR 범위 외라 `.disabled` 로 비활성화. 후속 PR 에서 처리.
+- Phase D2 (P1) record/replay/회귀 로그:
+  ```
+  commit e18aaa2 "test: P1 dark-mode snapshot baselines (13 TC × light/dark = 26)"
+  Onboarding: intro_loading (2)
+  AddDori: page1_emptySearch/searchResults/page3_amountError/datePickerOpen (8)
+  History: doriList_populated/editDori_default/datePickerOpen (8) + DoriListPopulated
+  MyPage: notificationSettings_allOn/allOff/myPage_logoutAlert/doriToggleSwitch_on/off (10)
+  Calendar P1 (calendarGrid_populated, dayDetailSheet_single/multiple) 누락 — Phase D3 sweep 항목으로 이월
+  ```
+- Phase D3 (P2) record/replay/회귀 로그:
+  ```
+  4 commits, 27 TC × light/dark = 54 PNG
+
+  c1ee90f AddDori P2  (7 TC × 2 = 14)  회귀: Page2 wedding → funeral 검출 → 원복 PASS

+
+  replay 2회차 모든 모듈 ** TEST SUCCEEDED **
+  ```
+- CI green run URL: _(채울 자리)_
+- `gh pr checks <PR#>` 결과: _(채울 자리)_
+
+### Phase D3 sweep 발견 결함 / 보류 항목
+
+- **PersonCard expanded baseline 보류** — `PersonCardView` 의 `isExpanded` 가 internal `@State` 라 외부에서 토글 불가. 컴포넌트가 `Binding` 받도록 리팩터 후 별도 PR 에서 추가. P2 catalog 의 1 TC 가 14 TC 로 줄었음.
+- **Calendar P1 누락 잔여** — e18aaa2 의 P1 26 PNG 에 calendarGrid_populated / dayDetailSheet_single / dayDetailSheet_multiple 가 없음. P2 commit 묶음에 포함하지 않음 (P1 보강은 별도 PR 또는 sweep 후속).
+- **사람-눈 visual sweep 1차 (claude multimodal, 13/27 dark PNG)** — 다음 결함 발견:
+
+  | # | 화면 | 결함 | 심각도 |
+  |---|---|---|---|
+  | 1 | `FCMPushTestView` (loading/default dark) | TextField 입력 텍스트가 어두운 회색/검은색 → 검은 배경에서 거의 안 보임. `userID=1`, `title=테스트 푸시`, `body=본문 메시지` 모두 light 색 박힌 의심. **다크 토큰(.textPrimary) 미적용** | 높음 |
+  | 2 | `TransactionRowView` (baddori dark) | 아이콘 배경이 light gray (`#E5E5E5` 추정). judori 의 `brandMain` 과 비교해 contrast 약함. 다크에서 디자인 의도 불확실 | 낮음 (디자인 결정 필요) |
+
+  정상 확인:
+  - DoriBarGraph balanced, TransactionRow judori, PersonCard collapsed, DoriSegmentControl judori
+  - AddDori Page1 selected / Page2 customEvent / Page3 amountTyped
+  - PartnerDoriHistory all, EditDori amountError, PartnerDoriDetail deleteAlert
+  - Search typedWithResults (placeholder limitation 별건), MyPage notif partial
+
+- **사람-눈 visual sweep 2차 (사용자 전수, 34 전체화면 dark PNG)** — 결함 종합:
+
+  | 카테고리 | 결함 | 영향 화면 | Fix |
+  |---|---|---|---|
+  | **A** | brandMain hex `#6C8FF0` 박힘 | AddDori Page3/EditDori 의 "예/아니오" 선택 버튼, NotificationSettings 토글 스위치 | `.brandMain` 토큰 사용 |
+  | **B** | DoriCommonAlert 다크 색 미적용 | PartnerDoriDetail deleteAlert, MyPage logoutAlert | popup bg→`.bgPrimary`(#111111), 취소 bg→`.bgSecondary`(#232323)/text→`.textPrimary`(#FDFDFD), 삭제 bg→`.brandMain`(#6C8FF0)/text→`.onBrand`(#111111) |
+  | **C** | "주도리" 텍스트/색 `#111111` 박힘 | DoriList populated, PartnerDoriHistory all | `.textPrimary` 토큰 사용 |
+  | **D** | 이미지 dark variant 없음 | datePicker 캘린더 아이콘 (AddDori Page3, EditDori), judori/baddori 아이콘 (TransactionRow, PartnerDoriHistory judoriOnly/baddoriOnly) | xcassets imageset 에 Dark Appearance pair 등록 |
+  | **E** | FCMPushTest TextField 텍스트 다크 미적용 | FCMPushTestView (default/loading) | `.textPrimary` 토큰 적용 |
+
+  통과: Onboarding 3장 (Kakao brand-fixed `#212223` 포함), AddDori Page1 전 3장 + Page2 전 3장 + Page3 amountZero/amountError/datePickerOpen, History DoriList empty + Search 3장 + EditDori datePickerOpen/amountError, MyPage default + NotificationSettings allOff.
+
+  Scope 외:
+  - **#1 CalendarGrid emptyMonth** — 디자인 전면 교체 예정, 사용자 직접 수정 영역으로 분리. 본 sweep 결과에서 제외.
+
+- **Phase D3 fix 진행** (commit `9107dbd`, `71d1693`, `11c4837`):
+
+  | 카테고리 | 상태 | 영향 baseline |
+  |---|---|---|
+  | A | 결함 아님 (이미 토큰 적용 확인) | — |
+  | B | ✓ DoriCommonAlert secondary text `.black` → `.textPrimary` | DoriCommonAlert/LogoutAlert/DeleteAlert light+dark 6장 |
+  | C | ✓ OnBrand.colorset dark `#FFFFFF` → `#111111` | 38장 dark 갱신 (DoriDesignSystem swatch/Alert/Toast/Button + Onboarding Intro + AddDori 전체 + Calendar segment + History BarGraph 등 + MyPage ToggleSwitch 등) |
+  | D | **보류** — 디자이너 PNG 작업 대기 | `Resources/Assets.xcassets` 의 `icon_judori`, `icon_baddori`, `iconCalendar` imageset 에 Dark Appearance 추가 + re-record 예정 |
+  | E | ✓ DoriTextField `.foregroundStyle(.textPrimary)` 명시 | FCMPushTest 4장 |
+
+  C 의 광범위 변경 후 핵심 재 sweep 진행 중.

+# Dark Mode Validation — (3) Feature 카탈로그 스냅샷
+
+## Context
+
+`docs/decision/supportDarkMode/validateDarkMode/PLAN.md` 가 다크모드 검증을 3단계로 추적 중이다:
+- (1) Asset Lint — 진행 중 (별도 PLAN)
+- (2) `assertSnapshotPair` 헬퍼 — 별도 PLAN
+- (3) **Feature 모듈 카탈로그 스냅샷 페어** — 본 PLAN
+
+`Projects/App/Sources/DoriApp.swift:103` 의 `.preferredColorScheme(.light)` 강제를 안전하게 풀기 위한 마지막 가드. 현재 14장 baseline 은 `Projects/Core/DoriDesignSystem/Tests/Snapshot/` 안의 컴포넌트 수준에 한정. 피처 화면이 다크에서 실제로 어떻게 보이는지에 대한 회귀 자동화는 0건.
+
+## Scope (확정)
+
+- **풀 카탈로그 P0+P1+P2 ≈ 106장 baseline** 일괄 도입
+- Mock 데이터는 **`DoriTestSupport` 공용 테스트 모듈 신설** 후 거기에 집중
+- Modal/Sheet 화면은 **단독 렌더링** 정책 (부모 합성 없음) — baseline 안정성 우선
+
+## Current TCs (14장 baseline)
+
+| 파일 (`Projects/Core/DoriDesignSystem/Tests/Snapshot/`) | 컴포넌트 | 케이스 |
+|---|---|---|
+| ColorTokenSnapshotTests | 12 의미 토큰 swatch | swatchSheet × light/dark |
+| PrimaryButtonSnapshotTests | PrimaryButton | enabled/disabled × light/dark |
+| DoriCommonAlertSnapshotTests | DoriCommonAlert | alert × light/dark |
+| DoriToastViewSnapshotTests | DoriToastView | success/error/info × light/dark |
+
+## Prerequisites (단계 0)
+
+1. **validateDarkMode (1) 머지 선행** — `Brand/Secondary.colorset` dark variant 누락 픽스가 들어가야 P0 baseline 이 변색된 다크를 정상으로 굳히지 않음
+2. **`DoriTestSupport` 모듈 신설** (`Projects/Core/DoriTestSupport/`):
+   - `Projects/Core/Project.swift` 에 `.doriFramework(DoriModules.testSupport.module, dependencies: [DoriModules.core.module.projectDependency])` 추가
+   - `DoriModules` enum (`Tuist/ProjectDescriptionHelpers/DoriTargets.swift`) 에 `testSupport` 케이스 추가
+   - 내용: `Sources/Mocks/Dori+Mock.swift`, `Partner+Mock.swift` 등 도메인 모델별 `public static let mock` / `mockList` 정적 팩토리. 필요 시 `Clients/` 에 client mockValue 보강 헬퍼
+   - 의존: `DoriCore` 만. 테스트 타깃에서만 의존시켜 production 바이너리 영향 차단
+3. **테스트 타깃 신설 4개** (`Projects/Feature/Project.swift`):
+   - `.doriUnitTests(DoriModules.onboarding.module, ...)`, `.addDori`, `.calendar`, `.myPage`
+   - 각 deps: `.external(.composableArchitecture)`, `.external(.snapshotTesting)`, `DoriModules.testSupport.module.projectDependency`
+   - History 타깃에도 `.external(.snapshotTesting)`, `.testSupport` 추가
+4. **시뮬레이터 디바이스 고정**: iPhone 16 UDID (DoriDesignSystem 스냅샷과 동일)
+5. **TCA Feature client mockValue 점검** — `addDoriAPIClient`, `calendarClient`, `myPageAPIClient`, `userNotificationSettingsClient` 등 누락된 경우 본 PLAN 중에 추가
+

+## File Layout

+```
+
+각 TC 는 명시적 두 어설션 — `UITraitCollection(userInterfaceStyle: .light)` / `.dark`. PLAN(2) 의 `assertSnapshotPair` 도입 후 일괄 한 줄로 마이그레이트.
+
+## Phasing
+
+본 PLAN 내부 단계:
+
+1. **Prerequisites 커밋** — `DoriTestSupport` 모듈 + 테스트 타깃 4개 + Tuist install/generate + 누락 client mockValue 보강
+2. **P0 커밋** — 6 TC 작성 + record. 다크 활성화 사전 검증 가능 시점
+3. **P1 커밋** — 17 TC 작성 + record
+4. **P2 커밋** — ~30 TC 작성 + record
+
+PR 분할은 추후 결정. 연관도 높아 단일 PR 권장.
+
+`assertSnapshotPair` 헬퍼는 별도 PLAN(2) — 본 PLAN 완료 후 도입 시 모든 TC 두 줄 → 한 줄 일괄 치환.
+
+## Verification
+
+1. 각 단계 record 1회차 → 자동 baseline 생성 (No reference 자동 기록)
+2. replay 2회차 → 전 TC 통과
+3. CI 통합: `xcodebuild test` 가 신설 테스트 타깃 4개를 포함하도록 scheme 갱신
+4. **`.preferredColorScheme(.light)` 제거 후보 PR 에서 baseline diff 발생량 = 시각 회귀 잠재 영역**. 0건이면 다크 활성화 가능, 다수면 픽스 후 re-record
+
+## Risk / Gotchas
+
+- **시뮬레이터 의존**: CI runner 에 iPhone 16 + Xcode 26.x 강제 필요. 호스트 차이로 깨지는 baseline 과 진짜 회귀를 분간해야 함.
+- **TCA 외부 client mockValue 누락**: P0 진입 전 모든 client 의 mockValue 정의 확인 필수. 없으면 본 PLAN 중에 추가.
+- **Stack/Tree navigation 단독 스냅샷의 시각 진실성**: 부모 합성 안 함 결정. scrim 위 컨텍스트가 일부 빠지지만 baseline 안정성 우선.
+- **`Brand/Secondary.colorset` dark 누락**: validateDarkMode (1) 머지 선행 필수.
+- **~106장 baseline = repo ~3MB 증가**: LFS 없이도 무방하나 시간 누적 시 재평가.

+## 1. What
+
+PLAN.md 의 In-scope 를 산출물 중심으로 재기술.
+
+### 신규 파일
+- `Scripts/lint_color_assets.py` — Python 3 표준 라이브러리 기반 정적 lint 스크립트

+- `.preferredColorScheme(.light)` 제거 ((2)(3) 완료 후)
+
+## 2. How
+
+4페이즈 순차 진행. 각 페이즈는 자체 git 커밋을 가지며, **Phase D 의 push 한 번으로 lint 3커밋이 함께 CI 트리거** 된다.
+
+### Phase A — 베이스라인 정리 (커밋 0)
+
+현재 working tree 에 lint 와 무관한 변경이 섞여 있다. 분리 안 하면 PR review 가 더러워지고 CI fail 시 원인 격리가 어렵다.
+
+대상:
+- Modified: `AGENTS.md`, `ARCHITECTURE.md`, `Projects/App/Sources/DoriApp.swift`, `README.md`, `docs/core/directory-structure.md`
+- Deleted: `docs/core/constitution.md`, `docs/core/feature-spec.md`, `docs/core/project-overview.md`
+- Added: `docs/decision/supportDarkMode/validateDarkMode/{PLAN.md, Implementation.md}`
+- Ignored: `build/` (`.gitignore` 에 이미 포함 가정)
+
+순서:
+1. `git status` 로 대상 재확인
+2. `git add` 로 위 파일들 스테이징 (build/ 제외)
+3. `git commit -m "chore: refresh docs and stage dark-mode work prep"`
+4. `git push origin feat/47-dark-mode-support`
+5. CI green 확인 (아래 "Hook 루프" 참조). green 이면 Phase B 진입. fail 이면 이 페이즈 안에서 해결.
+
+### Phase B — 로컬 구현 & 검증 (커밋 1)
+
+`Scripts/lint_color_assets.py` 작성. 핵심 룰:
+
+| 카테고리 | 룰 |
+|---|---|
+| `Brand/` | dark appearance 존재 |
+| `Brand/` | dark RGB == light RGB (정규화 후 비교) |
+| `Semantic/` | dark appearance 존재 |
+
+구현 요점:
+- 입력 루트: `Projects/Core/DoriDesignSystem/Resources/Colors.xcassets/`
+- 순회: `**/*.colorset/Contents.json`
+- 색상 정규화: `components.red/green/blue` 가 `0xFF` 형식이면 16진수 → 정수, `0.500` 형식이면 0~1 실수 → 반올림 정수
+- 색공간 불일치(`color-space` 가 다름) 도 mismatch 로 fail
+- 첫 위반에서 abort 하지 말고 전체 순회 후 stderr 에 위반 전체 + 위반 개수 출력, exit 1
+- pip 의존성 0 (json/pathlib/sys 만)
+
+로컬 검증 (스크립트만, 데이터는 아직 그대로):
+```bash
+python3 Scripts/lint_color_assets.py
+# → "Brand/Secondary.colorset is missing dark appearance" 보고 + exit 1
+echo $?  # → 1
+```
+
+회귀 시나리오 (스크립트 정확성 증거):
+```bash
+# Semantic 의 dark 일시 제거
+# (Edit 또는 임시 git stash)
+python3 Scripts/lint_color_assets.py
+# → "Semantic/BgPrimary.colorset is missing dark appearance" 추가 보고
+# 원복
+git restore Projects/Core/DoriDesignSystem/Resources/Colors.xcassets/Semantic/BgPrimary.colorset/Contents.json
+```
+
+커밋:
+```bash
+git add Scripts/lint_color_assets.py
+git commit -m "chore: add color asset lint script"
+```
+
+### Phase C — 데이터 정리 (커밋 2)
+
+`Brand/Secondary.colorset/Contents.json` 에 dark appearance 추가. RGB 는 light 와 동일하게 박아 Brand 룰(`dark == light`) 만족.
+
+`Brand/KakaoYellow.colorset/Contents.json` 신규 생성. light/dark 모두 `#FEE500` (sRGB, alpha 1.000).
+
+로컬 검증:
+```bash
+python3 Scripts/lint_color_assets.py
+echo $?  # → 0
+```
+
+`tuist generate` 후 ResourceSynthesizer 가 `DoriColors.kakaoYellow` (혹은 동등) 를 자동 생성하는지 확인:
+```bash
+tuist generate --no-open
+grep -r "kakaoYellow\|KakaoYellow" Projects/Core/DoriDesignSystem/Derived/Sources/ | head
+```
+
+커밋:
+```bash
+git add Projects/Core/DoriDesignSystem/Resources/Colors.xcassets/Brand/
+git commit -m "fix: add dark appearance to brand colorsets"
+```
+
+### Phase D — CI 통합 (커밋 3) + Hook 루프
+
+`.github/workflows/build.yml` 의 "Generate workspace" step 다음, "Build project" step 이전에 삽입:
+
+```yaml
+      - name: Lint color assets
+        run: python3 Scripts/lint_color_assets.py
+```
+
+커밋 & push:
+```bash
+git add .github/workflows/build.yml
+git commit -m "ci: wire color asset lint into build workflow"
+git push origin feat/47-dark-mode-support
+```
+
+#### Hook 루프 (핵심)
+
+PR #48 에 push 가 닿으면 `Build App` 워크플로가 자동 트리거된다. 다음 루프로 green 까지 추적:
+
+```bash
+# 1. 최신 run ID 와 상태
+RUN_ID=$(gh run list --branch feat/47-dark-mode-support --limit 1 \
+  --json databaseId --jq '.[0].databaseId')
+
+# 2. 진행 hook — CI 끝날 때까지 블록, exit code 로 성공(0)/실패(1)
+gh run watch "$RUN_ID" --exit-status
+WATCH_EXIT=$?
+
+# 3. 실패 시 원인 추출
+if [ $WATCH_EXIT -ne 0 ]; then
+  gh run view "$RUN_ID" --log-failed | tail -200
+fi
+
+# 4. 최종 확인
+gh pr checks 48
+```
+
+#### Fail 분류 & 대응
+
+| 원인 분류 | 예시 | 대응 |
+|---|---|---|
+| **Lint/Asset 범위** | 스크립트 버그(false positive/negative), colorset JSON 파싱 오류, 누락된 dark 가 추가 발견, RGB 정규화 불일치 | 로컬에서 자동 수정 → 재커밋(같은 페이즈 위에 누적 또는 amend 대신 fix 커밋) → 재push → 재watch |
+| **범위 외** | macOS runner 다운, Xcode `latest-stable` 변경으로 빌드 깨짐, mise/Tuist 설치 실패, 네트워크 timeout, Common.xcconfig fallback 충돌 | 사용자에게 로그 요약 보고 후 대기. 자동 수정 시도 금지 |
+
+루프는 **green 한 번 확인** 으로 종료. lint step 만 green 이고 build/test 가 fail 인 부분 성공도 fail 로 간주.
+
+## 3. When
+
+- **순차 의존**: Phase A → B → C → D. A 가 분리되지 않으면 lint 커밋이 다른 변경과 섞여 PR review 와 CI fail 원인 격리가 모두 어려워진다.
+- **Phase A 의 게이트**: 베이스라인 push 의 CI 가 green 이어야 Phase B 진입. 베이스라인이 빨간 상태에서 lint 를 얹으면 빨강이 둘이 되어 원인 구별 불가.
+- **로컬 검증 후 push**: 각 Phase 내에서는 로컬에서 의도한 exit code/결과를 확인하기 전까지 push 하지 않는다. CI 시간 낭비 방지.
+- **Phase D 의 push 는 lint 3커밋이 모두 쌓인 후 한 번에**: 중간 커밋만 push 하면 lint script 만 있고 데이터 fix/CI step 이 없는 상태라 CI 가 fail 한다. 의미 없는 빨강이 PR 에 박힌다.
+- **Hook 루프의 타임아웃**: `gh run watch` 가 자체적으로 종료까지 블록. 사람 timeout 은 두지 않고 CI 완료를 기다린다.
+
+## 4. 종료기준 (Definition of Done)
+
+다음을 **모두** 만족해야 done.
+
+- [ ] `python3 Scripts/lint_color_assets.py` 가 결함 정리 후 exit 0
+- [ ] 회귀 시나리오 — `Semantic/BgPrimary.colorset` 의 dark 일시 제거 시 스크립트가 fail 보고 (스크립트 정확성 증거, 원복 후 다시 pass)

+# Dark Mode Validation — (1) Asset Lint
+
+## Context
+
+Dori 앱은 현재 `Projects/App/Sources/DoriApp.swift:103` 의 `.preferredColorScheme(.light)` 로 다크모드를 강제 비활성화 한 상태로 출시되어 있다. 디자인 시스템(`DoriDesignSystem`) 의 Semantic 토큰 12개는 이미 light/dark 페어가 정의되어 있고, 컴포넌트 스냅샷 테스트도 light/dark 페어로 검증 중이다. 그러나 다음 두 사각지대로 인해 라이트 강제를 안전하게 풀 수 없다.
+
+1. **Brand colorset 의 dark 누락** — `Brand/Secondary.colorset` 등은 dark appearance 가 정의돼 있지 않다. 시스템이 자동으로 어둡게 변환하면서 브랜드 색이 깨진다.
+2. **카카오 옐로(`#FEE500`) 같은 외부 SDK 색상의 자동 변환** — SDK 가 자체 제공하는 색은 colorset 으로 등록돼 있지 않아 lint 범위 밖이고, 시뮬레이터에서 어둡게 변색되는 현상이 실측 확인됨.
+
+두 결함 모두 현재의 스냅샷 회귀 자동화로는 잡히지 않는다 — 스냅샷은 "그렇게 그려진 결과" 를 정상으로 박아 통과하기 때문이다.
+
+이 PLAN 은 다크 활성화 전 검증 자동화의 **1단계 (정적 lint)** 만 다룬다. 후속:
+- (2) `assertSnapshotPair` 헬퍼 — 별도 PLAN
+- (3) Feature 모듈 카탈로그 스냅샷 페어 — 별도 PLAN
+
+## Scope
+
+### In scope
+- Brand/Semantic colorset 의 dark appearance 누락 검출
+- Brand colorset 의 `dark RGB == light RGB` 검증 (브랜드 색 보존)
+- 카카오 옐로 `#FEE500` 을 `Brand/KakaoYellow.colorset` 으로 신규 정의 → lint 범위 진입
+- 현재 결함 1건 정리: `Brand/Secondary.colorset` 에 dark appearance 추가
+- CI (`.github/workflows/build.yml`) 에 lint step 추가
+
+### Out of scope (별도 작업)
+- 카카오 버튼 코드가 실제로 `Brand/KakaoYellow.colorset` 을 참조하도록 리팩터 (Feature 영역, 별도)
+- pre-commit hook / Tuist build phase 통합
+- 시스템 자동 변환을 우회하는 다른 색상 정의 패턴
+- assertSnapshotPair 헬퍼 및 Feature 카탈로그 스냅샷 ((2), (3) PLAN)
+
+## Approach
+
+### A. Lint 스크립트 (Python, 표준 라이브러리만)
+
+`Scripts/lint_color_assets.py` 신규 생성. CI 러너에 기본 설치된 Python 3 사용, pip 의존성 없음 (json/pathlib/sys 만).
+
+**입력**: `Projects/Core/DoriDesignSystem/Resources/Colors.xcassets/{Brand,Semantic}/**/*.colorset/Contents.json`
+
+**룰**:
+| 카테고리 | 룰 | 위반 메시지 예시 |
+|---|---|---|
+| Brand/ | dark appearance 존재 | `Brand/Foo.colorset is missing dark appearance` |
+| Brand/ | dark RGB == light RGB (16진수 정규화 후 비교) | `Brand/KakaoYellow.colorset dark RGB differs from light (light=#FEE500, dark=#B89A1C)` |
+| Semantic/ | dark appearance 존재 | `Semantic/Foo.colorset is missing dark appearance` |
+
+**동작**:
+- 모든 colorset 을 순회 후 위반 항목 전체를 stderr 출력 (첫 위반에서 abort 하지 않음 — 사용자가 한 번에 다 보고 고치도록)
+- 위반 있으면 exit 1, 없으면 exit 0
+- exit 시 위반 개수를 stderr 마지막 줄에 요약
+
+### B. 데이터 결함 정리
+
+- `Brand/Secondary.colorset/Contents.json` 에 dark appearance 추가 (RGB 는 light 와 동일하게 박아 룰 만족)
+- `Brand/KakaoYellow.colorset/Contents.json` 신규 생성 (light/dark 모두 `#FEE500`)
+
+### C. CI 통합
+
+`.github/workflows/build.yml` 의 "Generate workspace" step 다음, "Build" step 이전에 lint step 추가:
+
+```yaml
+- name: Lint color assets
+  run: python3 Scripts/lint_color_assets.py
+```
+
+`tuist generate` 와 무관하게 동작하는 정적 검사라 generate 전 실행도 가능하지만, **빌드 직전 배치**가 "lint → build → test" 의 자연스러운 피드백 순서.
+
+## Files
+
+| 작업 | 경로 |
+|---|---|
+| Create | `Scripts/lint_color_assets.py` |
+| Create | `Projects/Core/DoriDesignSystem/Resources/Colors.xcassets/Brand/KakaoYellow.colorset/Contents.json` |
+| Modify | `Projects/Core/DoriDesignSystem/Resources/Colors.xcassets/Brand/Secondary.colorset/Contents.json` |
+| Modify | `.github/workflows/build.yml` |
+
+## Implementation Notes
+
+- `Contents.json` 의 색상은 `color.color-space` 가 srgb 또는 display-p3 둘 다 가능. 룰 비교 시 색공간이 다르면 일단 mismatch 로 fail (Brand 컬러는 srgb 통일을 권장).
+- `components` 의 `red/green/blue/alpha` 는 `0xFF` 같은 16진수 또는 `0.500` 같은 0~1 실수 두 형태가 모두 유효. 정규화 함수 필요 (16진수 → 0~255 정수, 실수 → 반올림 0~255 정수).
+- 룰 위반은 colorset 경로(상대 경로)로 출력 — 사용자가 즉시 파일을 열 수 있게.
+- 향후 확장 여지로 `EXEMPT` 마커(예: colorset 옆 `.lint-exempt` 파일)를 비워두되 이 PLAN 에선 구현하지 않음. 화이트리스트 필요 시점에 추가.
+
+## Verification
+
+1. **로컬 실행 (스크립트만)**
+   - `python3 Scripts/lint_color_assets.py` → 결함 정리 전: `Brand/Secondary.colorset` 누락 보고 + exit 1

+- 카카오 버튼 (`Projects/Feature/Onboarding/Sources/...`) 이 실제로 `DoriColors.kakaoYellow` 를 참조하도록 리팩터 — 후속 작업. 이 PLAN 은 lint 가 "잡을 수 있는 상태" 까지만.
+- `.preferredColorScheme(.light)` 제거 시점은 (2)(3) PLAN 완료 + 카탈로그 다크 스냅샷 전수 통과 후.
