+# v0.3.1 Cut F — 멀티모달 vision AI Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** F24 — Ollama vision 모델 (gemma3 family default) 활용. 이미지 + raw_text 결합 prompt → title/summary/tags 자동 생성. Capability detection (app launch + manual refresh) + InferenceProvider 확장 + AiWorker 통합 + Configure UI dropdown.
+
+**Architecture:** `isVisionCapable(model)` pure 함수 가 family/families/name 기반으로 vision 가능 모델 판정. `refreshVisionCache(deps)` 가 `/api/tags` 호출 후 settings 에 cache. AiWorker 가 `note.media.length > 0 && visionModel` 둘 다 충족 시 vision path (5MB cap + base64 변환). Configure UI 가 cache 기반 dropdown + manual refresh.
+
+**Tech Stack:** undici/fetch (Ollama API), Node fs/promises (이미지 base64 변환), Electron IPC, React 19 + zustand 5, vitest 4 + RTL.
+
+**선행 문서:**
+
+- `docs/superpowers/specs/2026-05-09-v031-cut-f-design.md` — source spec (Cut F 정정 반영: 단위 679, 실제 SettingsService API, 'skipped' enum 미도입, fallback 미구현)
+- `docs/superpowers/specs/2026-04-25-dogfood-feedback.md` — F24

+## File Structure
+
+**Create:**
+
+- `src/main/services/VisionDetect.ts` — `isVisionCapable(model)` pure + `refreshVisionCache(deps)` async (Ollama /api/tags)
+- `src/main/ai/visionPrompt.ts` — `buildVisionPrompt(text, todayKst, dueCandidates, vocab)` pure

+- `src/preload/index.ts` — 3 bridge
+- `src/shared/types.ts` — `getSettings()` 반환에 vision_* 3 필드 + InboxApi 3 메서드
+- `src/main/index.ts` — `void refreshVisionCache(...)` whenReady 안 + AiWorker 생성자에 settings 주입
+- `src/renderer/inbox/components/settings/AiProviderSection.tsx` 또는 SettingsPage — VisionSection 마운트
+- `tests/unit/SettingsService.test.ts` — vision 4 메서드 round-trip
+- `tests/unit/LocalOllamaProvider.test.ts` — vision body 분기 회귀
+- `tests/unit/AiWorker.test.ts` — 기존 mock 에 settings stub 추가 (생성자 변경)
+- `package.json` — version 0.3.0 → 0.3.1
+- `docs/superpowers/specs/2026-04-25-dogfood-feedback.md` — F24 promoted

+- [ ] **Single write path 강제 (Cut C/D/E 정책)**: 본 cut 은 새 데이터 path 추가 없음 — `notes_fts` / `note_revisions` / `note_tags` mutation 없음 (vision 결과는 기존 `updateAiResult` path 활용 → 이미 검증됨). 회귀 검사 4-path invariant 유지.

+
+---
+
+## Risk
+
+- **vision 모델 한국어 정확도**: gemma3 family 가 한국어 약하면 다른 family 추천 갱신 (메모리 정책). dogfood 검증 필요
+- **Ollama 가 vision images 무시 (모델 misclassify)**: capability detection false-positive — 사용자가 dropdown 에서 다른 모델 선택해 우회. 자동 fallback 미구현 (YAGNI)
+- **base64 메모리 폭주**: 5MB cap 적용. 다중 이미지 시 N×5MB = 메모리 누적 — vision 호출 후 image array 즉시 GC. 본 cut 의 dogfood 규모 (메모당 < 3 이미지) 무시
+- **capability detection 실패 silent**: 첫 launch 시 network 실패 → cache 빈 채로 진행. 사용자가 설정 페이지에서 "다시 감지" 클릭 → 직접 trigger 가능
+- **AiWorker 생성자 변경**: 기존 test 모두 mock 갱신 필요 (typecheck 가 catch). 누락 시 typecheck red
+- **F23 OFF (ai_enabled=false) 시 자동 OFF**: refreshVisionCache 가 ai_enabled 체크 → ai_disabled 분기. AiWorker 의 vision path 진입 자체가 ai_enabled=true 가정 — F23 OFF 시 vision path 미도달 (자명)
+- **e2e**: Cut C/D/E 와 동일 — 본 cut 미수행, main 머지 후 검증
