# AI_and_ML 폴더 시스템 메타

## 매 한 줄
> **"매 폴더의 system manifest — index, ownership, cleanup status, conventions 의 single source of truth"**. 매 normal content document 매 X — 매 tooling / agent 가 매 폴더 metadata 를 read 할 때 entry point.

## 매 핵심

### 매 폴더 정체성
- **Path**: `10_Wiki/Topics/AI_and_ML/`
- **Scope**: AI, ML, DL, NLP, CV, RL, LLM agents, MLOps, AI ethics/policy 의 거의 모든 wiki entry.
- **Volume**: ~700+ files (2026-05 기준), 매 wiki 의 largest domain folder.
- **Owner**: caliversedevpm@gmail.com
- **House style**: Korean + technical English mix, "매" topic-marker prefix on section headers.

### 매 cleanup phases
- **Phase 1 (2026-05-08)**: 매 placeholder + frontmatter scaffold 자동 생성.
- **Phase 2 (2026-05-10~)**: manual content cleanup — 매 batch agent 가 매 file 처리, full or REDIRECT 형식.
- **Phase 3 (planned)**: cross-link consolidation, canonical 결정, alias graph 정합성.

### 매 frontmatter convention
- `id`: `wiki-2026-0508-<slug>` (Phase 1 origin date 유지).
- `status`: `verified` | `duplicate` | `stub` | `draft`.
- `canonical_id`: `self` 또는 canonical doc 의 slug.
- `duplicate_of`: REDIRECT 의 경우 `[[Canonical-Title]]` (wikilink in quotes).
- `source_trust_level`: A (authoritative), B (community / blog), C (speculative).
- `confidence_score`: 0.0-1.0.
- `tags`: lowercase kebab-case, comma-separated array.
- `last_reinforced`: ISO date of latest manual review.

### 매 file types
1. **Full content**: 150-250 lines, 매 spec 의 full 포맷.
2. **REDIRECT (duplicate)**: ~25 lines, canonical 로 redirect.
3. **System / meta**: this file. 매 폴더당 1개.

### 매 cleanup spec reference
- Spec file: `/Volumes/Data/project/Antigravity/Wiki/CLEANUP_SPEC.md`
- Memory note: `feedback_wiki_continuous.md` — 매 batch 자동 진행 mode.

## 💻 패턴

### 1. 폴더 file count 확인
```bash
ls "/Volumes/Data/project/Antigravity/Wiki/10_Wiki/Topics/AI_and_ML/" | wc -l
```

### 2. 미처리 stub 찾기 (frontmatter status check)
```bash
grep -l "status: stub" "/Volumes/Data/project/Antigravity/Wiki/10_Wiki/Topics/AI_and_ML/"*.md
```

### 3. Canonical 분포 확인
```bash
grep -h "^canonical_id:" "/Volumes/Data/project/Antigravity/Wiki/10_Wiki/Topics/AI_and_ML/"*.md \
  | sort | uniq -c | sort -rn | head -20
```

### 4. Wikilink graph extract (Python)
```python
import re, glob
from collections import defaultdict

graph = defaultdict(set)
for path in glob.glob("/Volumes/Data/project/Antigravity/Wiki/10_Wiki/Topics/AI_and_ML/*.md"):
    with open(path, encoding="utf-8") as f:
        text = f.read()
    src = path.rsplit("/", 1)[-1].removesuffix(".md")
    for m in re.findall(r"\[\[([^\]|]+)", text):
        graph[src].add(m.strip())

print(f"Files: {len(graph)}, edges: {sum(len(v) for v in graph.values())}")
```

### 5. Batch frontmatter validation
```python
import yaml, glob, sys
required = {"id", "title", "category", "status", "canonical_id", "tags"}
errors = []
for p in glob.glob("/Volumes/Data/project/Antigravity/Wiki/10_Wiki/Topics/AI_and_ML/*.md"):
    with open(p, encoding="utf-8") as f:
        text = f.read()
    if not text.startswith("---"):
        errors.append((p, "no frontmatter"))
        continue
    fm_text = text.split("---", 2)[1]
    try:
        fm = yaml.safe_load(fm_text)
    except Exception as e:
        errors.append((p, f"yaml: {e}")); continue
    missing = required - set(fm)
    if missing:
        errors.append((p, f"missing: {missing}"))
print(*errors, sep="\n")
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| 새 wiki entry 생성 | Phase 1 scaffold → Phase 2 full content |
| 기존 file 매 의미 매 다른 file 와 overlap | REDIRECT (duplicate_of) |
| 한 topic 의 specialized aspect | full content + canonical 로 wikilink |
| 매 신뢰 못 할 source | source_trust_level: C, 매 followup 필요 표시 |

**기본값**: 매 file 매 full content 로 시도 → 매 명확히 duplicate 면 REDIRECT.

## 🔗 Graph
- 응용: 매 폴더 내 모든 entry

## 🤖 LLM 활용
**언제**: 매 batch agent 매 폴더 작업 시작 시 read — 매 conventions/scope 확인.
**언제 X**: 매 user-facing content reference 매 X — 매 internal meta only.

## ❌ 안티패턴
- **이 file 을 normal entry 로 취급**: 매 system meta — 매 user-facing content 가 아님.
- **다른 폴더에 같은 _system.md 통합**: 매 폴더별 separate (scope/convention 다를 수 있음).
- **Frontmatter convention drift**: 매 새 field 추가 시 매 spec update 필수.

## 🧪 검증 / 중복
- Verified (CLEANUP_SPEC.md, folder structure, Phase 1 scaffold output).
- 신뢰도 A.
