+# v0.2.3 #6 리마인드 1 spike — Design Spec
+
+> 작성: 2026-05-02 · v0.2.3 dogfood feedback roadmap §3 #6 (7번째 / 마지막 cut)
+
+## 1. Goal
+
+Inbox 상단에 "오늘 회상해볼 노트" 1건 추천 배너 (`RecallBanner`) 도입. 7일 이상 안 본 노트 중 가장 오래된 1건을 제시하여 사용자가 자기 기록을 재방문할 기회 제공. 4종 telemetry (`recall_shown` / `recall_opened` / `recall_dismissed` / `recall_snoozed`) 로 효과 측정 인프라 마련.
+
+## 2. Decisions (mini-brainstorm 합의)
+
+| # | 질문 | 선택 | 이유 |
+|---|---|---|---|
+| Q1 | 다음에 snooze 영속화 | **A** in-memory | `expiredSnoozeUntilMs` 패턴 일관, schema migration v4 회피, dogfood telemetry 보고 v0.2.4 영속화 결정 |
+| Q2 | `ageDays` 의미 | **B** `last_recalled_at ?? created_at` 기준 | algo 의 "7일 안 본 노트" trigger 와 동일 axis, 재추천 분포 측정 가치 |
+
+자명 결정 (질문 없이 패턴 따름):
+- Banner 위치: `ExpiryBanner` 다음 (stack 끝, 시간 민감도 가장 낮음)
+- 0건 시: `null` return (`ExpiryBanner` 패턴)
+- Snooze duration: KST 다음 자정 (`snoozeExpired` 패턴)
+- "열어보기" 동작: `scrollIntoView` (NoteCard 항상 expanded — expand 동작 X)
+
+## 3. Architecture & data flow
+
+```
+Inbox 마운트 시:
+  loadInitial() → recallCandidate fetch (별도 fetch, 단일 노트 또는 null)
+
+RecallBanner render (recallCandidate !== null && !snoozed):
+  ┌─ "오늘 회상해볼 노트" + 노트 제목 + (N일 전)
+  ├─ [열어보기] → scrollIntoView(noteCardRef) + markRecallOpened(id)
+  │              → telemetry: recall_opened
+  ├─ [다음에] → store.snoozeRecall() (KST 다음 자정까지 in-memory)
+  │            → telemetry: recall_snoozed
+  └─ [더 이상] → dismissRecall(id) (DB: recall_dismissed_at = now)
+                 → telemetry: recall_dismissed
+
+Banner 첫 렌더 시 자동 emit: recall_shown { noteId, ageDays }
+
+다음 fetch 트리거:
+  - markRecallOpened / dismissRecall 후 store 가 자동 다음 후보 fetch
+  - refreshMeta (focus / inbox:noteUpdated) 도 fetch
+```
+
+### 3.1 Invariants
+
+1. **단일 후보 fetch** — `LIMIT 1` + `ORDER BY created_at ASC` (가장 오래된 1건)
+2. **KST 보정** — SQL 의 `date('now')` 자리 모두 `date('now','+9 hours')`
+3. **마감 임박 노트 제외** — `due_date < today` 인 노트는 ExpiryBanner 영역 (#5) 이라 회상 후보에서 빠짐
+4. **Snooze in-memory** — `recallSnoozeUntilMs` store 변수, KST 다음 자정 (ExpiryBanner 패턴)
+5. **emit 순서** — `recall_shown` (banner 첫 렌더) → `recall_opened/dismissed/snoozed` (사용자 액션)
+6. **Snooze 시 `recall_shown` 1회만** — 같은 후보가 다시 보여도 `recall_shown` 재emit 안 함 (notes 1건당 session 1 shown — `recallShownIds: Set<string>` in-memory)
+
+## 4. Components
+
+### 4.1 `NoteRepository`
+
+#### `findRecallCandidate(): Note | null`
+
+```sql
+SELECT * FROM notes
+WHERE (last_recalled_at IS NULL OR last_recalled_at < date('now','+9 hours','-7 day'))
+  AND (recall_dismissed_at IS NULL OR recall_dismissed_at < date('now','+9 hours','-30 day'))
+  AND ai_status = 'done'
+  AND deleted_at IS NULL
+  AND (due_date IS NULL OR due_date >= date('now','+9 hours'))
+ORDER BY created_at ASC
+LIMIT 1
+```
+
+기존 `hydrate(row)` 사용 (이미 `last_recalled_at` / `recall_dismissed_at` 매핑 있음).
+
+#### `markRecallOpened(id: string, now: string): void`
+
+```sql
+UPDATE notes SET last_recalled_at = ?, updated_at = ? WHERE id = ?
+```
+
+#### `dismissRecall(id: string, now: string): void`
+
+```sql
+UPDATE notes SET recall_dismissed_at = ?, updated_at = ? WHERE id = ?
+```
+
+### 4.2 `CaptureService` (5 신규 메서드)
+
+```typescript

+  return Math.max(0, Math.floor((nowMs - refMs) / 86_400_000));
+}
+```
+
+### 4.3 IPC (5 신규 channels)
+
+```typescript
+ipcMain.handle('inbox:listRecallCandidate', () => deps.capture.listRecallCandidate());
+ipcMain.handle('inbox:markRecallOpened', (_e, id: string) => deps.capture.markRecallOpened(id));

+ipcMain.handle('inbox:emitRecallSnoozed', (_e, id: string) => deps.capture.emitRecallSnoozed(id));
+```
+
+### 4.4 Preload + InboxApi shared type
+
+```typescript
+// preload/index.ts
+listRecallCandidate: () => ipcRenderer.invoke('inbox:listRecallCandidate'),
+markRecallOpened: (id: string) => ipcRenderer.invoke('inbox:markRecallOpened', id),
+dismissRecall: (id: string) => ipcRenderer.invoke('inbox:dismissRecall', id),
+emitRecallShown: (id: string) => ipcRenderer.invoke('inbox:emitRecallShown', id),

+dismissRecall(id: string): Promise<{ note: Note }>;
+emitRecallShown(id: string): Promise<void>;
+emitRecallSnoozed(id: string): Promise<void>;
+```
+
+### 4.5 `telemetryEvents.ts` zod
+
+```typescript
+const RecallShownPayload = z.object({
+  noteId: z.string().min(1),
+  ageDays: z.number().int().nonnegative()
+}).strict();
+
+// recall_opened / recall_dismissed / recall_snoozed → 기존 NoteIdPayload 재사용
+```
+
+union 15 → **19** (recall_shown + recall_opened + recall_dismissed + recall_snoozed).
+
+### 4.6 `telemetryStats.ts`
+
+- DailyRow +4 cols (`recall_shown`, `recall_opened`, `recall_dismissed`, `recall_snoozed`)
+- accumulators: `recallShownCount`, `recallOpenedCount`, `recallDismissedCount`, `recallSnoozedCount`, `recallAgeDaysSum`
+- summary lines:
+  ```
+  - 회상 추천: shown {N} / opened {O} / dismissed {D} / snoozed {S} (열림율 {O/N}%)
+  - 회상 평균 ageDays: {avg}
+  ```
+  N=0 시 `(데이터 없음)`
+
+### 4.7 `TelemetryService.EmitInput` union 15 → 19
+
+### 4.8 Renderer store (`src/renderer/inbox/store.ts`)
+
+```typescript
+interface InboxState {
+  // ... existing ...
+  recallCandidate: Note | null;
+  recallSnoozeUntilMs: number | null;
+  recallShownIds: Set<string>;  // session-local, "1 shown per note per session"
+  loadRecallCandidate: () => Promise<void>;
+  openRecall: (id: string) => Promise<void>;
+  dismissRecallNote: (id: string) => Promise<void>;  // store action 명, IPC 와 구별
+  snoozeRecall: () => Promise<void>;
+}
+```
+
+`refreshMeta` + `loadInitial` 가 `loadRecallCandidate` 도 호출.
+
+`openRecall(id)`:
+- `inboxApi.markRecallOpened(id)` → DB 갱신
+- `loadRecallCandidate()` → 다음 후보 fetch
+- (스크롤은 RecallBanner 컴포넌트가 자체 처리)
+
+`dismissRecallNote(id)`:
+- `inboxApi.dismissRecall(id)` → DB 갱신
+- `loadRecallCandidate()` → 다음 후보 fetch
+
+`snoozeRecall()`:
+- `recallSnoozeUntilMs = nextKstMidnight()` (`snoozeExpired` 패턴)
+- 현재 candidate noteId 기준 `inboxApi.emitRecallSnoozed(id)`
+
+### 4.9 RecallBanner 컴포넌트
+
+**파일**: `src/renderer/inbox/components/RecallBanner.tsx` (신규)
+
+- 위치: `<ExpiryBanner />` 다음 (App.tsx)
+- 첫 렌더 시 `useEffect` 가 `recallShownIds` 체크 후 미emit 시 `inboxApi.emitRecallShown(id)` 호출 + Set 에 추가
+- Banner UI: 노트 제목 + ageDays + 3개 버튼 (열어보기 / 다음에 / 더 이상)
+- `null` return: candidate=null OR snoozed (Date.now < snoozeUntilMs)
+- snoozeUntilMs 만료 시 setTimeout re-render 트리거 (ExpiryBanner 패턴)
+
+### 4.10 NoteCard ref 시스템 (scroll target)
+
+App.tsx 가 `noteRefs: Map<noteId, HTMLDivElement | null>` ref store 보유 + RecallBanner 가 store 의 ref 를 lookup 후 `scrollIntoView({ behavior: 'smooth', block: 'center' })` 호출.
+
+구체 구현:
+- `App.tsx` 가 `useRef<Map<string, HTMLDivElement | null>>(new Map())` 보유
+- 각 `<NoteCard>` 에 `ref={(el) => { noteRefs.current.set(note.id, el); }}` 전달 (NoteCard 가 ref forwardRef 지원 필요)
+- RecallBanner 가 `noteRefs` prop 으로 받아 사용
+
+**대안 (단순)**: `document.getElementById(\`note-${id}\`)` — App.tsx 의 NoteCard 가 `id={\`note-${note.id}\`}` 만 추가하면 됨. **이 spike 에선 이 단순 방식 채택** (ref 시스템 복잡도 회피).
+
+## 5. Privacy invariant
+
+- `recall_shown.payload`: `{ noteId, ageDays }` — noteId 기존 패턴, ageDays 정수
+- `recall_opened/dismissed/snoozed.payload`: `{ noteId }` — `NoteIdPayload` 재사용
+- `.strict()` zod 가드 + extra field 거부 테스트
+
+## 6. Tests (≥17개)
+
+### NoteRepository.test.ts (5)
+1. 빈 db → null
+2. last_recalled_at 5일 전 노트 제외 (7일 이내)
+3. last_recalled_at 8일 전 노트 후보 (7일 초과)
+4. recall_dismissed_at 25일 전 제외, 35일 전 후보
+5. deleted_at / ai_status='pending' / due_date < today 모두 제외
+
+### CaptureService.test.ts (4)
+6. listRecallCandidate → repo.findRecallCandidate
+7. markRecallOpened → repo + recall_opened emit + last_recalled_at 갱신 검증
+8. dismissRecall → repo + recall_dismissed emit + recall_dismissed_at 갱신 검증
+9. emitRecallShown → ageDays 정확 (last_recalled NULL 시 createdAt 기준)
+
+### telemetryEvents.test.ts (3)
+10. recall_shown valid parse (noteId + ageDays)
+11. recall_shown extra field 거부 (privacy)
+12. recall_opened/dismissed/snoozed valid parse (noteId only)
+
+### telemetryStats.test.ts (2)
+13. shown/opened/dismissed/snoozed 누적 + 열림율 계산
+14. 평균 ageDays 계산

+### store.recall.test.ts (신규, 3)
+15. snoozeRecall → snoozeUntilMs KST 다음 자정 + emitRecallSnoozed 호출
+16. openRecall → API 호출 + recall_shown 한 번만 emit (recallShownIds set)
+17. dismissRecallNote → 후보 다시 fetch
