refactor: v2.2.195-201 — slashRouter god-file 해체 (–95%) + 인프라 5개 추출

아키텍처 감사 결과 HIGH 2건 + MED 2건 + LOW 1건 — 7 라운드 정리 시리즈.
기능 변경 없음, 순수 구조 정리.

**slashRouter.ts: 4,174 → 201줄 (–3,973, –95%)**
**agent.ts: 1,617 → 1,551줄 (–66, –4%)**

v2.2.195: eventSourcedStore + SystemPromptBlock registry
  - createEventStore<E>(opts) — 4 store (customers/hire/runway/feedback) I/O 240줄 중복 제거
  - _turnCtx 5 named string field → 1 Map<string, string> (새 verification block 추가 25곳→1곳)
  - buildAstraModeSystemPrompt: 5 ternary gate + 5 위치 → 1 for-loop join

v2.2.196: trackers cluster split
  - src/features/teamops/handlers/_shared.ts (fmtKrw/parseAmount/daysUntil/parseTaskOwner/stageEmoji/STAGE_ORDER/TERMINAL_STAGES)
  - src/features/teamops/handlers/trackers.ts (runway/customers/hire)
  - src/features/teamops/handlers/index.ts (barrel)
  - extension.ts 에 side-effect import (순환 import 회피)

v2.2.197: mtimeFileCache + PostAnswerHook registry
  - src/lib/mtimeFileCache.ts — createMtimeFileCache<T>(name, parse) (terminologyBlock + termValidator 2-cache invariant 자동화)
  - src/agent/postAnswerHooks/{types,index}.ts — Devil/SelfCheck/TermValidator 3 _maybeX method → 1 runPostAnswerHooks(ctx) loop
  - agent.ts –66줄

v2.2.198: dashboards cluster split
  - src/features/teamops/handlers/dashboards.ts (morning/evening/cohort/weekly)

v2.2.199: coordination + communication clusters split
  - src/features/teamops/handlers/coordination.ts (task/decisions/onesie/blocked/standup)
  - src/features/teamops/handlers/communication.ts (draft/feedback)
  - callLmSynthesis export 노출 (communication 이 사용)
  - 옛 parseTaskOwner local 정의 삭제 (_shared.ts 사용)

v2.2.200: system cluster split
  - src/features/system/handlers.ts (memory/glossary/help)

v2.2.201: datacollect cluster split + LLM 인프라 추출
  - src/features/datacollect/handlers.ts (research/benchmark/youtube/blog/wikify/meet)
  - src/features/datacollect/llm.ts (callLmSynthesis + repairKoreanGlitches + bridgeErrorRemedy)
  - slashRouter import 4개로 축소: vscode/logInfo/getBridgeBaseUrl/bridgeErrorRemedy

**최종 slashRouter (201줄):**
- REGISTRY Map + registerSlashCommand/listSlashCommands/isSlashCommand
- handleSlashCommand (dispatcher + 에러 처리)
- Webview interface + chunk helper
- getRecentSlashCommands ring buffer (actionability scoring 용)

**미래 부담 감소 metrics:**
- 새 슬래시 명령: god-file 끝에 함수 + register → 1 파일 + 1 register call
- 새 verification block: 5곳 편집 → 1 set call
- 새 event store: 60줄 boilerplate → createEventStore 한 줄
- 새 post-answer hook: 3 step → 1 push
- 새 mtime cache: Map + invariant 관리 → createMtimeFileCache 한 줄

+ * 배경: customers, hire, runway, feedback 4개 store 가 같은 패턴 4번 반복
+ * (getXFilePath / readX / appendX / countX) — byte-for-byte 중복 ~240줄.
+ * 한 곳에서 잡으면 BOM/인코딩 edge case 등 fix 도 한 번에 전파.

+ *       validate: (e) => typeof e.id === 'string' && typeof e.customerId === 'string',
+ *   });
+ *   store.read(); store.append(event); store.count(); store.getFilePath();
+ *
+ * 도메인별 로직 (computeStates 등) 은 그대로 도메인 파일에 남음 — 본 모듈은
+ * I/O 만 추상화.
