+### 이번 PR: 연결 즉시 의미 준비형 질의
+
+ContextFlow의 Enrich·Federation·Memory는 의미를 발견하고 축적한다. 이번 PR은
+그 구조를 교체하지 않고, **semantic catalog(연결별 허용 의미 목록)가 활성화된
+연결의 실행 경계**를 추가한다. 서버가 연결 시 catalog를 만들고 질문마다 후보를
+제한하면, 모델은 SQL 대신 허용된 metric/dimension ID·집계와 질문에서 가져온
+filter·기간만 선택한다. 이 PR에는 catalog 생성·검토·컴파일·실행 코어, 공개 API,
+Discord 관리 UX와 SQLite/DuckDB 검증이 함께 포함된다.
+
+#### 1. 기존 시스템에서 무엇이 달라졌나
+
+
+
+| 영역 | Catalog 없는 기존 연결 | Catalog가 활성화된 연결 |
+|---|---|---|
+| 모델 질의 도구 | `run_sql`, Explore, Enrich | `semantic_query`와 `ask_user`만 노출 |
+| 모델 출력 | SQL 문자열 | metric/dimension ID, 집계, filter, 기간 |
+| Enrich | row sample 기반 보강 가능 | 모델 도구에서는 제외; 같은 source/fingerprint의 기존 설명만 후보로 재사용 |
+| 의미 확정 | 모델과 기존 의미 계층에 의존 | 업무 표현·집계·분류 공개 범위를 서로 분리해 사람 검토 |
+| 실행 | 기존 Safety pipeline | catalog/source 재검증 → 서버 SQL 컴파일 → 기존 Safety |
+| 실패 처리 | legacy 질의 경로 | raw SQL로 우회하지 않고 추가 질문·검토·차단 |
+
+Memory·Ingestion·Federation의 저장 기능과 Discord 인터페이스는 그대로 남는다.
+다만 catalog가 활성화된 **자연어 DB 질문 turn**에서는 모델이 raw SQL·Explore·
+Enrich를 호출하지 못한다.
+
+#### 2. 연결할 때 catalog를 어떻게 만드는가
+
+
+
+1. **메타데이터만 읽기(metadata scan)**
+ - table·column·type·nullability·PK/FK·DB comment만 읽는다.
+ - 연결 시 raw row, 범주 값 목록, PII 값을 sample하지 않는다.
+
+2. **물리 column 분류**
+ - PII·credential·free text·key·비지원 type은 `blocked_columns`로 보낸다.
+ - numeric measure는 `MetricSpec`, time/boolean/categorical은
+ `DimensionSpec` 후보로 만든다.
+ - 각 table에는 물리적인 source-record `COUNT(*)` metric을 별도로 만든다.
+ - 일반 numeric column은 발견 즉시 업무 지표로 승인하지 않는다.
+
+3. **Join과 검색 표현 후보 생성**
+ - 선언된 단일-column FK의 child → parent 방향만 join 후보로 등록한다.
+ - physical name과 DB comment를 후보 표현(alias)으로 만든다.
+ - 동일 source와 동일 스키마 지문(fingerprint)의 재연결에서만 기존 Enrich 설명과
+ 사람 검토 결정을 이어받는다.
+ - `LANG2SQL_AUTO_METADATA_ENRICH=auto`와 실제 provider가 설정됐거나 `llm`
+ 모드를 명시하면 metadata-only alias 보강을 한 번 수행한다.
+ - 충돌 alias·값 목록형 표현·URL/email/SQL형 문자열은 제거한다. LLM 보강
+ 결과도 승인된 업무 의미, join, 집계, 공개 권한이 아니다.
+
+4. **정규화·식별·원자적 활성화**
+ - 물리 schema snapshot을 정렬한 뒤 SHA-256 fingerprint를 만든다.
+ - encrypted credentials, catalog JSON, connection binding을 하나의 SQLite
+ transaction으로 활성화한다.
+ - 세 상태가 어긋나거나 catalog가 손상되면 legacy `run_sql`로 돌아가지 않는다.
+
+재연결·schema 변경·검토 변경은 서로 다른 상태 값으로 추적한다. 현재 상태와 맞지
+않는 이전 후보와 draft는 재사용하지 않는다.
+
+
+Catalog 상태 필드 자세히 보기
+
+| 상태 | 의미 | 바뀌는 시점 |
+|---|---|---|
+| `source_id` | scope와 canonical DSN/extras를 비가역적으로 묶은 실행 source identity | DB·credential·연결 option 변경 |
+| `connection_generation` | 현재 활성 연결 세대 | 재연결할 때마다 |
+| `fingerprint` | 물리 schema snapshot의 지문 | 재연결 scan에서 schema 변경 감지 |
+| `review_revision` | 사람 검토 결정의 동시성 marker | 표현·집계·공개 상태 변경 |
+| catalog/policy version | 저장 형식과 분류·shortlist 규칙 버전 | 코드 정책이 변경될 때 |
+
+`catalog.version`은 내용이 바뀔 때마다 증가하는 revision이 아니다. 물리 변경은
+`fingerprint`, 사람 결정 변경은 `review_revision`으로 구분한다. Discord에서는
+`/semantic_status`로 현재 후보·보강·검토 상태를 확인할 수 있다.
+
+
+
+#### 3. 작은 모델이 실제로 하는 일
+
+- **후보 검색은 서버가 수행한다.** 현재 구현은 vector search가 아니라 physical
+ name·승인 alias·후보 alias를 이용한 문자열 기반 검색이다.
+- **입력 크기를 제한한다.** table 6개, metric 12개, dimension 12개, tool schema
+ 12 KiB 이내로 제한한다. 작은 catalog는 상한 안의 전체 후보를 줄 수 있고,
+ 넓은 catalog는 질문에 정확히 나타난 metadata 표현으로 좁힌다.
+- **모델은 typed slot만 채운다.** metric/dimension ID, 허용 집계, 질문에서 복사한
+ filter 값과 기간, 미지원 요구사항을 구조화한다. SQL·table·join·dialect는
+ 선택하지 않는다.
+- **서버가 다시 검증한다.** candidate token은 질문·사용자·대화·source·연결
+ 세대에 묶고, plan 단계에서 현재 catalog/revision으로 shortlist와 정책을
+ 다시 검사한다.
+- **미확정 의미는 실행하지 않는다.** 같은 요청자가 15분 안에 검토하면 exact
+ draft를 재검증해 이어갈 수 있다. 다른 관리자 승인·만료·서버 재시작 뒤에는
+ 질문을 다시 제출해야 한다.
+
+```text
+질문 status가 paid인 주문의 amount 합계
+
+서버 후보 metric:orders.amount
+ dimension:orders.status
+ aggregate: SUM · operator: EQ
+
+모델 출력 metric_id=metric:orders.amount
+ aggregate=SUM
+ filter.dimension_id=dimension:orders.status
+ operator=EQ · value="paid"
+
+서버 처리 현재 catalog/review/source 확인
+ → 유일한 안전 FK·bound parameter로 SQL 컴파일
+ → Safety·결과 공개 정책
+ → read-only 실행 또는 명시적 차단
+```
+
+작은 모델의 성능을 높이는 핵심은 더 많은 추론을 요구하는 것이 아니라,
+**연결 시점에 후보를 준비·관리하고 질문 시점에 선택 문제로 축소하는 것**이다.
+
+#### 4. 현재 검증 경계
+
+- 업무 의미를 metadata만으로 완전히 복원한다고 주장하지 않는다. 사람 피드백은
+ catalog에 저장되고 같은 source/fingerprint에서만 재사용된다.
+- 문자열 기반 후보 검색이며 vector/VDB recall은 아직 구현하지 않았다.
+- 모델이 자연어의 숨은 조건을 전혀 발견하지 못하는 planner 문제는 별도 평가 대상이다.
+- 검토형 compiler·timeout/cancel·read-only 실행의 현재 근거는 기존 file-backed
+ SQLite와 DuckDB다. 다른 connector의 연결 가능성과 안전 실행 검증은 구분한다.

핵심 원칙: **로직은 포트(추상)에만 의존, 어댑터(구체)는 가장자리에만**. 그래서 새 LLM·새 DB·새 frontend를 *기존 코드 안 건드리고* 끼울 수 있습니다.
+### 연결 즉시 의미 준비형 질의 경로
+
+검토형 질의는 기존 frontend·tenancy·agent loop·4기둥을 사용하는 연결별 실행
+모드다. Catalog가 활성화되면 모델의 `run_sql`을 `semantic_query`로 바꾸고, 서버가
+후보 제한·사람 검토·typed plan·SQL 컴파일을 담당한다. 지원하지 않는 요청은
+legacy 경로로 우회하지 않는다. 구성 요소 경계와 catalog 생성 과정은
+[`REVIEWED_SEMANTIC_QUERY.md`](./REVIEWED_SEMANTIC_QUERY.md)의 도식을 참고한다.

## What's stub (be honest)
-- **No real database execution.** `PostgresExplorer` returns canned
- `orders`/`users` schema and sample rows. `run_sql` enforces the safety gate and
- goes through the executor, but there is no live psycopg connection in V1 — real
- execution is v1.5. `/connect` stores a DSN (encrypted) but it is not yet used to
- open a connection.
-- **No reasoning without `OPENAI_API_KEY`.** The offline `FakeLLM` produces
- deterministic tool cycles, not real answers.
+- **The default no-DB demo is stubbed.** Without `LANG2SQL_DB_URL` or a completed
+ Discord `/setup`, the concierge uses the canned `PostgresExplorer` fixture.
+ `/setup` connections use the real SQLAlchemy/D1 adapters; the required driver
+ and network access must be present for that database.
+- **No reasoning without a configured model.** The offline `FakeLLM` produces
+ deterministic tool cycles, not real answers. Configure `OPENAI_API_KEY`, or
+ both `LANG2SQL_LLM_BASE_URL` and `LANG2SQL_LLM_MODEL` for a local compatible
+ server such as Ollama.
- **No rate limiting** in V1 — keep deployments to small trial guilds so token
spend stays bounded (rate limit + per-user token caps are v1.5).
+- **No role/row/column authorization model** in the semantic runtime. Discord
+ is admin-only by default and may be opened only to explicitly configured
+ channels; the connected database credential must still enforce least privilege.
+- **Public governed execution proof is limited to existing file-backed SQLite
+ and DuckDB.** Both are opened read-only. Other connectors may scan metadata,
+ but governed execution remains blocked where safe statement
+ timeout/cancellation has not been verified; do not treat a successful remote
+ connection as execution approval.
+- **The embedded API is SQL-free.** For a non-Discord host, use
+ `connect → candidates → human feedback → typed plan → execute`; apply each
+ review with an explicit human choice and type-check the execution result
+ before reading rows. See [`LIBRARY_API.md`](LIBRARY_API.md).

+# 모델이 SQL을 작성하지 않는 애플리케이션 통합 API
+
+`Lang2SQLRuntime`은 Discord가 아닌 호스트가 내부 semantic service나 SQL 객체를
+직접 다루지 않고 검토형 질의를 사용할 수 있게 하는 비동기 진입점이다.
+
+| 단계 | 호스트가 보내는 것 | 성공 응답 |
+|---|---|---|
+| `connect` | DB 연결 정보와 `CallContext` | metadata scan 결과와 초기 검토 항목 |
+| `candidates` | 원 질문 | bounded metric/group/filter/DATE 후보 |
+| `feedback` | 사람이 고른 허용 선택지 | 저장된 검토 결정과 재개 가능한 다음 단계 |
+| `plan` | 후보 ID로 조립한 `QueryDraft` | 일회용 `PreparedPlan` 또는 `ReviewRequired` |
+| `execute` | 같은 사용자·대화·DB에 묶인 plan | typed columns와 rows |
+
+`connect`는 물리명과 실제 DB comment를 후보로 자동 준비한다. 같은 source와 전체
+물리 fingerprint로 재연결할 때만 기존 Enrich 설명 캐시를 다시 사용한다.
+`LANG2SQL_AUTO_METADATA_ENRICH=auto` 또는 `llm`이면 metadata-only LLM 보강을
+시도하며, `Connected.scan`의 `enrichment_status`, `enriched_object_count`,
+`enrichment_reason`으로 성공·제한 사유를 확인할 수 있다. 어느 결과도 승인된
+업무 의미, join, 집계 또는 공개 권한을 만들지 않는다.
+
+모델은 SQL을 받거나 반환하지 않는다. 필터 값도 SQL 문자열, candidate DTO, repr,
+audit parameter detail 또는 영속 review record에 들어가지 않는다. 같은 프로세스의
+검토 자동 재개에 필요한 원 질문과 typed 값은 메모리에만 최대 15분 보관된다.
+
+## 먼저 실행해 보기
+
+다음 예제는 임시 SQLite DB를 직접 만들기 때문에 Discord, 기존 DB, LLM, 네트워크가
+필요하지 않다. 이 예제가 직접 만든 공개 fixture에 한해 정해진 검토 선택을 적용한
+뒤 공개 API의 전체 흐름을 실행한다.
+
+```bash

+
+예제에서 쓰는 테이블과 값은 실행할 때 임시 디렉터리에 생성되고 종료 시 제거된다.
+실서비스에서는 예제의 자동 선택 함수를 그대로 쓰지 말고 사용자의 명시적 결정을
+`FeedbackRequest`로 전달해야 한다.

+## Token과 재시작 경계
+
+`CandidateSet.source`는 진단용 표시가 아니라 안전 경계다. 재연결 뒤 과거 source로
+만든 `QueryDraft`는 `candidate_source_stale`로 차단된다. `ReviewRequired`도 source,
+catalog fingerprint/version, 분류 정책, 객체 revision과 15분 유효시간에 묶인다.
+`candidate_token`은 scope·사용자·대화·source·연결 세대·원 질문 hash를 묶은
+opaque HMAC이다.
+host는 `CandidateSet`에서 받은 token과 원 질문을 그대로 `QueryDraft`에 주입해야 하며,
+모델이 질문을 바꾸거나 다른 후보 응답의 token을 재사용하면
+`candidate_question_mismatch`로 차단된다.
+이 token은 15분짜리 Discord action token이나 일회용 실행 권한이 아니다. 같은 runtime
+인스턴스와 source 안에서는 별도 만료시각 없이 질문 binding을 증명하지만, `plan`은
+매번 현재 catalog와 shortlist를 다시 검증한다. Host는 한 질의가 끝나면 token을
+폐기하고, 새 사용자 turn에는 `candidates`를 다시 호출한다.
+프로세스가 재시작되면 사람의 검토 결정은 저장할 수 있지만 민감 draft는 복원하지
+않고 후보 HMAC 서명키도 회전한다. 이때 `FeedbackApplied.next`는 비어 있으며 host는
+사용자에게 같은 질문을 다시 받아 `candidates`부터 호출하고, 새 `source`와
+`candidate_token`으로 `QueryDraft`를 다시 조립해야 한다. 과거 draft/token을 그대로
+재사용하면 `candidate_question_mismatch`로 차단되는 것이 정상이다.
+사람 검토 변경은 catalog와 audit를 같은 SQLite transaction에 기록하므로, 현재
+`ContextConcierge`에 외부 audit port를 주입한 구성에서는 feedback이
+`semantic_audit_not_atomic`으로 차단된다. 실행 audit의 외부 port 지원과 의미 변경의
+원자적 audit 지원을 같은 것으로 간주하지 않는다.
+
+## 후보와 사람 검토
+
+- `MetricCandidate`: ID, 안전하게 제한한 label, 질문에 실제 있는
+ `grounded_phrase`, 허용 집계를 제공한다.
+- `FilterCandidate`: 위 필드와 `allowed_value_kinds`를 제공한다. host는 이 타입과
+ 맞지 않는 literal을 보내지 않아야 하며 서버도 다시 검증한다.
+- `TimeCandidate`: native `DATE` 차원만 제공하고 endpoint kind는 `DATE`로 고정한다.
+- `ReviewCandidate`: 아직 선택할 수 없는 차원과 필요한 조치만 알린다. review token,
+ DB 값, 질문의 필터 값은 포함하지 않는다.
+- 후보에 없거나 의미가 모호한 항목을 host가 임의 ID로 채우면 plan이 차단한다.
+
+연결 응답은 첫 20개 검토만 표시한다. 더 많은 차원이 있어도 질문에 정확히 맞는
+항목은 `candidates`의 `review_required_dimensions`에 나타나고, typed draft가 실제로
+그 항목을 참조할 때 하나의 on-demand review가 발급된다.
+
+## 현재 실행 계약
+
+지원:
+
+- 기존 file-backed SQLite와 DuckDB의 read-only governed execution
+- `SUM`/`AVG`/검토된 공개 범위의 `MIN`/`MAX`, source-record `COUNT(*)`
+- categorical group-by와 유일한 declared child-to-parent FK 경로
+- 최대 8개 AND 필터, exact `EQ` 또는 최대 20개 값의 `IN`
+- 문자열·정수·소수·불리언 bound parameter
+- native `DATE`의 ISO date `[start, end)` 기간창
+
+의도적으로 차단:
+
+- raw SQL, row projection, OR/NOT, 부분 문자열·자유 검색
+- relative time, timestamp timezone, fiscal/cohort calendar 추정
+- 자유 수식과 파생 지표 실행
+- composite FK, fan-out, 동률 join path
+- 사람 검토 전 공개 값, PII/credential/서술문 컬럼
+- 검증된 timeout/cancel 계약이 없는 원격 dialect의 governed execution
+
+파생 지표용 AST/DAG·grain·unit·NULL/0 나눗셈 계약은 내부 IR에 정의돼 있지만,
+compiler는 정책 전파와 dialect 증거가 추가될 때까지 실행을 fail-closed한다.
+
+## DuckDB 설치
+
+```bash
+python -m pip install -e ".[duckdb]"
+```
+
+DuckDB는 존재하는 로컬 파일만 허용한다. 연결은 read-only이고 외부 접근,
+extension 자동 설치/로드와 community extension을 끈 뒤 설정을 잠근다. `:memory:`와
+존재하지 않는 경로는 governed execution으로 승격하지 않는다.

+# 연결 즉시 의미 준비형 질의 — 설계 및 실행 계약
+
+이 문서는 semantic catalog가 활성화된 연결의 실행 계약을 설명한다. Discord 명령
+사용법은 [`USAGE.md`](USAGE.md), 외부 애플리케이션 통합은
+[`LIBRARY_API.md`](LIBRARY_API.md), 전체 프로젝트 구조는
+[`ARCHITECTURE.md`](ARCHITECTURE.md)를 따른다.
+
+## 책임 경계
+
+| 구성 | 책임 |
+|---|---|
+| ContextFlow | Enrich·Federation·Ingestion·Memory로 의미 후보와 대화 맥락을 발견·축적 |
+| Semantic catalog | 현재 DB source의 허용 객체, 차단 컬럼, join, 검토·공개 상태를 저장 |
+| 모델 | 질문별 후보에서 ID·집계·filter·기간·미지원 요구사항을 구조화 |
+| 서버 | 현재 catalog와 정책을 검증하고 SQL을 컴파일·감사·실행 |
+| 사람 | 자동으로 확정할 수 없는 업무 표현·집계·분류 공개 범위를 승인 또는 거절 |
+
+Catalog가 없는 연결은 기존 `run_sql`·Explore·Enrich 경로를 사용한다. Catalog가
+활성화된 자연어 DB 질문에서는 모델 도구를 `semantic_query`와 `ask_user`로
+제한한다. 이 상태에서 catalog가 손상되거나 연결 binding이 맞지 않아도 raw SQL
+경로로 돌아가지 않는다.
+
+
+
+
+
+## 용어
+
+| 용어 | 이 문서에서의 의미 |
+|---|---|
+| semantic catalog | 연결별 허용 의미 목록. 물리 metadata와 검토 상태를 함께 보관한다. |
+| typed plan | SQL이 아닌 구조화된 실행 요청. 선택한 ID·집계·분류·filter·기간을 담는다. |
+| physical fingerprint | 정규화한 schema snapshot의 SHA-256 지문 |
+| review revision | 사람의 의미·공개 결정이 바뀔 때 사용하는 동시성 marker |
+| candidate token | 후보 응답을 질문·사용자·대화·source·연결 세대에 묶는 무결성 값. 실행 권한은 아니다. |
+
+## Catalog 생성 계약
+
+
+
+
+
+1. 어댑터에서 table·column·type·nullability·PK/FK·DB comment를 읽는다.
+ 연결 단계에서 raw row나 범주 값 목록을 sample하지 않는다.
+2. PII·credential·서술형 text·key·비지원 type을 차단한다. Numeric measure는
+ metric 후보, time/boolean/categorical은 dimension 후보가 된다. 각 table의
+ 물리 source-record `COUNT(*)`는 별도 metric으로 만든다.
+3. 선언된 단일-column FK의 child → parent 방향만 join 후보로 등록한다.
+4. Physical name과 DB comment를 후보 alias로 만든다. 동일 source와 동일
+ fingerprint에서만 기존 Enrich 설명과 사람 검토 결정을 이어받는다.
+5. 설정된 경우 metadata-only LLM이 alias 후보를 보강한다. 충돌·값 목록형·URL·
+ email·SQL형 표현은 제거하며, 제안은 의미·join·집계·공개 권한을 승인하지 않는다.
+6. 정규화한 schema snapshot으로 fingerprint를 만들고 encrypted credentials,
+ catalog, connection binding과 generation을 하나의 SQLite transaction으로
+ 활성화한다.
+
+Catalog format version, physical fingerprint, connection generation, review revision,
+classification policy version은 서로 다른 변경을 추적한다. Shortlist policy version은
+catalog가 아니라 질문별 envelope에 기록한다. Format version을 catalog 내용
+revision처럼 사용하지 않는다.
+
+## 질문 실행 계약
+
+1. 서버가 active catalog·binding·generation 일치를 확인한다.
+2. 물리명·승인 alias·후보 alias의 문자열 기반 검색으로 후보를 제한한다. 상한은
+ table 6개, metric 12개, dimension 12개, tool schema 12 KiB다.
+3. 모델은 후보 ID와 허용 집계, 질문에 실제 있는 filter/time 표현, 미지원
+ 요구사항을 typed slot으로 조립한다. SQL·table·join·dialect는 출력하지 않는다.
+4. 서버가 candidate token, 현재 catalog/revision의 shortlist, 질문 grounding,
+ 타입, disclosure, 유일한 child → parent FK 경로를 다시 검증한다.
+5. 업무 표현·집계·분류 공개가 미확정이면 review 또는 clarification으로 멈춘다.
+ 같은 요청자가 15분 안에 검토하면 exact draft를 재검증해 재개할 수 있다.
+6. 다른 관리자 승인·만료·프로세스 재시작 뒤에는 검토 결정만 남기고 원 질문을
+ 다시 제출받는다.
+7. 서버가 bound parameter SQL을 컴파일하고 기존 SafetyPipeline, contributor
+ 보호, 공개 정책, audit, catalog stamp를 통과한 결과만 표시한다.
+
+## 기존 ContextFlow와의 관계
+
+| 기존 구성 | 이번 PR에서의 관계 |
+|---|---|
+| Enrich가 값 샘플로 컬럼 의미 가설을 생성 | legacy 연결에서는 유지한다. source·물리 fingerprint가 같은 재연결이면 저장된 설명을 후보로 재사용하되 승인으로 간주하지 않는다. 새 연결 보강은 row 값을 LLM에 보내지 않는다. |
+| Semantic federation이 조직·채널·사용자별 정의를 축적 | 그대로 유지한다. 팀별 용어 정의와 현재 DB 질문의 실행 승인은 서로 다른 책임이다. |
+| agent loop가 `run_sql(sql=...)`을 호출 | catalog가 없는 연결에서는 유지한다. catalog가 활성화된 연결에서만 `semantic_query`로 교체한다. |
+| 기존 Safety pipeline이 SQL을 검사 | 그대로 사용하고, 앞단에 candidate·typed plan 검증을, 뒷단에 결과 공개 정책과 source stamp 검사를 추가한다. |
+
+## Discord 접근 및 검토 권한
+
+- DB 연결과 semantic governance 명령은 guild 관리자만 실행한다.
+- 자연어 DB 질의는 기본적으로 guild 관리자만 허용한다.
+- 일반 구성원은 운영자가 `LANG2SQL_DISCORD_QUERY_CHANNEL_IDS`에 명시한 상위
+ 채널에서만 질문할 수 있다. thread는 상위 채널 정책을 따른다.
+- DM은 사용자별 scope/session으로 격리해 허용한다.
+- 잘못된 채널 허용 목록은 일부만 적용하지 않고 봇 시작을 실패시킨다.
+- 이 allowlist와 결과 억제 규칙은 DB row/column RBAC를 대신하지 않는다.
+
+현재 역할별 DB 정책은 범위 밖이다. 따라서 초기 실험은 read-only 전용 DB 계정,
+최소 권한, 신뢰된 전용 채널을 사용해야 한다.
+
+## 공개 라이브러리 경계
+
+Discord가 아닌 호스트는 모델이 SQL을 작성하지 않는 `Lang2SQLRuntime`을 사용한다.
+`connect → candidates → human feedback → typed plan → execute` 순서를 지키며,
+호스트/모델은 SQL을 주고받지 않는다. `connect`는 메타데이터만 읽고, `candidates`는
+질문에 맞춘 bounded ID와 타입만 준다. 사람이 `ReviewRequest.allowed_choices`에서
+명시적으로 고른 값을 `feedback`에 제출한 뒤에만 공개 범위나 의미 검토가 바뀐다.
+`execute`는 같은 사용자·대화·DB source에 묶인 일회용 `PreparedPlan`만 받는다.
+
+typed draft의 predicate는 명시적 AND, exact `EQ` 또는 값 최대 20개의 `IN`만
+허용하며 모든 값은 bound parameter가 된다. 한 질의에는 최대 8개 filter와
+dimension별 1개 filter만 허용한다. predicate 실행은 source의 공개 데이터 확인과
+해당 dimension의 공개 승인이 모두 필요하다. 기간은 native `DATE` 차원의 ISO date
+`[start, end)` 창만 받는다. 기존 파일을 read-only로 연 SQLite와 DuckDB만 검토
+기반 실행을 지원한다. 상세 DTO와 안전한 검토 루프는
+[`LIBRARY_API.md`](LIBRARY_API.md)에 있다.
+
+## 안전 경계
+
+보이는 실행 계약은 네 가지다.
+
+- Catalog가 활성화되면 모델의 raw SQL 도구를 제거하고, 상태가 손상돼도 fallback하지 않는다.
+- PII 의심 컬럼과 미승인 분류값은 후보·결과에서 기본 차단한다.
+- Token과 review는 질문·사용자·source·연결 상태에 묶고, 만료·재연결·재시작 시 재검증한다.
+- 실행 전후와 결과 게시 직전에 catalog stamp·Safety·audit를 확인한다.
+
+
+토큰·재시작·감사 세부 계약
+
+- 현재 scope/연결에 semantic catalog가 활성화되면 `run_sql`은 모델 도구 목록에서 제거된다.
+- catalog JSON이나 연결 binding이 손상돼도 raw SQL 경로로 되돌아가지 않는다.
+- PII 의심 컬럼은 metric/dimension 후보에 포함하지 않는다.
+- 문자열 차원의 관리자 공개 승인과 질문 표현 연결 승인을 분리한다.
+- 공개 승인 전 후보 ID는 모델 도구 enum에도 포함하지 않는다.
+- Discord stewardship의 객체 후보·행동 토큰은 15분, action, source ID, 연결 세대에
+ 묶인다. 객체 토큰은 관련 object state/epoch를, catalog-wide public/reset 토큰은
+ 전체 catalog revision을 검증한다. metric/dimension map과 dimension release는 추가로
+ 경고를 실행한 reviewer와 payload에 묶여 경고 없는 실행이나 payload 변경을 차단한다.
+- 공개 API의 `CandidateSet.candidate_token`은 별도 15분 action capability가 아니다.
+ runtime 인스턴스의 HMAC 키와 scope·actor·conversation·source·원 질문에 묶이고,
+ plan 시점에 현재 catalog shortlist를 다시 검증한다. 재연결·runtime 재시작에는
+ 폐기되며 host도 한 질의 조립 뒤 저장하지 않고 새 `candidates`에서 다시 받는다.
+- review commit, pending 삭제, receipt, audit은 하나의 SQLite transaction이다.
+- pending review 전용 KV에는 질문 원문·필터 값·날짜 경계를 저장하지 않는다. 같은
+ 프로세스에서는 15분 메모리 payload로 정확히 재개하고, 재시작 뒤에는 결정을
+ 적용한 다음 원 질문 재제출을 안내한다. 다만 Discord의 일반 대화 transcript에는
+ 사용자가 보낸 질문이 별도 보존되므로 운영 환경은 session 보관 정책을 함께
+ 정해야 한다.
+ 같은 reviewer·ID·choice 재시도는 idempotent이고 다른 actor/choice 재사용은 차단된다.
+- parent → child fan-out, 경로 없음, 동률 경로는 SQL 없이 차단한다.
+- child → parent join은 nullable FK와 orphan fact를 버리지 않도록 `LEFT JOIN`한다.
+- 실행 전·실행 후·audit 후 catalog stamp를 확인하고, Discord 렌더 직전에도 같은
+ stamp를 재검사한다. revoke/reset/재연결이 감지되면 준비된 행을 폐기한다.
+- 요청한 group-by가 빠지거나 모델이 복사한 표현이 질문에 없으면 멈춘다.
+- 서버가 인식했거나 모델이 명시한 미지원 filter·기간·단위·업무 조건은 버리고
+ 실행하지 않는다. 모델이 자연어의 숨은 조건을 전혀 발견하지 못하는 문제는 별도
+ planner 평가 대상이다.
+- `ask_user`는 단독 tool call로만 허용되고, clarification을 반환하면 해당 turn을
+ 즉시 중단한다. Discord에는 SQL 형태를 제거한 한 번짜리 transient 상태만 저장한다.
+- 기존 `/enrich`와 `/org_setup` 자체를 제거하지 않는다. 다만 검토형 연결에서는
+ raw-value sample-to-LLM 경로를 도구 목록에서 비활성화한다.
+- DSN·extras·catalog는 한 SQLite transaction으로 활성화한다.
+- `/semantic_reset`도 15분 action token의 경고/확인 두 단계가 필요하다.
+
+
+
+## 결과 공개 정책
+
+두 정책은 별개다.
+
+1. **질의 권한**: 누가 연결 DB에 질문할 수 있는가.
+2. **결과 억제**: 허용된 질문의 집계나 범주를 표시해도 되는가.
+
+비공개 기본값에서는 grouped/ungrouped 여부와 무관하게 `SUM`, `AVG`, source-row
+`COUNT`의 실제 기여 행이 5개 미만이면 결과 전체를 차단한다. 빈 결과와
+NULL-only metric도 차단한다. `MIN`/`MAX`는 contributor 수로 극값 노출을 숨길 수
+없으므로 컴파일하지 않는다.
+
+`controlled_grouped` 차원은 각 결과 그룹의 실제 metric contributor 최소 5를
+유지한다. metadata-safe boolean처럼 자동 안전 판정된 차원은 제한된
+`public_grouped`로 사용할 수 있다. 그 밖에 관리자가 승격한 `public_grouped`와
+predicate 사용은 `/semantic_public_data`로 현재 연결 전체가 공개·비개인
+데이터임을 확인해야 한다. 다만 최대 50범주와 표시 라벨 128자 제한은 유지한다.
+공개 데이터 범위에서도 하나라도 controlled 차원이 포함되면 contributor 보호와
+`MIN`/`MAX` 차단이 다시 적용된다.
+
+최소 contributor 5는 보수적인 출력 억제 규칙이지 k-anonymity, differential
+privacy, row-level security 또는 사용자 권한 보장이 아니다.
+
+## 현재 지원 범위
+
+지원:
+
+- 숫자 컬럼의 표현별 `SUM`/`AVG`
+- 공개 데이터 범위이며 controlled 차원이 없는 경우의 `MIN`/`MAX`
+- 모든 테이블의 명시적 physical source-record `COUNT(*)` (PK 불필요)
+- categorical dimension group-by
+- declared FK를 따라가는 유일한 child → parent 1~N hop join
+- 기존 file-backed SQLite와 DuckDB의 read-only 검토 기반 실행과 결과 비교
+- metadata-only 문자열 공개 후보 및 수치 지표 후보
+- 모든 비차단 dimension의 metadata-only phrase mapping과 conflict 검증
+- 질문 시점의 metric/dimension review와 immutable draft 재개
+
+의도적으로 차단 또는 clarification:
+
+- timestamp/relative/fiscal/cohort 기간과 검토되지 않은 단위 변환
+- raw SQL, row projection, OR/NOT·부분 문자열·자유 filter expression
+- 자유 수식과 파생 지표 실행
+- composite FK
+- parent-to-child fan-out 또는 여러 최단 join path
+- PII/credential/서술문/식별자형 문자열 컬럼
+- 숫자형 calendar/code/identifier의 자동 역할 분류
+- 역할별 row/column policy
+
+검토형 경로가 인식한 제한은 조용히 버리지 않는다. typed blocker로 끝나며 raw
+SQL 생성으로 우회하지 않는다. 현재 실제 안전 실행 증거는 existing file-backed
+SQLite와 DuckDB뿐이다. 다른 DB를 연결할 수 있다는 사실과 같은 compiler·timeout·
+취소 동작이 검증됐다는 주장은 구분하며, 검증되지 않은 원격 dialect 실행은
+fail-closed한다.
+
+## LLM에 남아 있는 역할
+
+모델은 사용자 문장에서 shortlist 안의 metric/dimension 후보와 아직 표현하지
+못한 의무를 구조화한다. 서버는 다음을 독립적으로 강제한다.
+
+- ID가 질문별 bounded allowlist에 있는가
+- 모델이 복사한 표현이 실제 질문에 있는가
+- 표현·컬럼·집계 연결이 현재 source/revision에 대해 확인됐는가
+- join이 metric grain을 늘리지 않는 유일한 child-to-parent path인가
+- 기간·단위·group-by 의무가 누락되지 않았는가
+- SQL과 결과가 safety/disclosure gate를 통과했는가
+
+따라서 작은 모델이 후보를 잘못 고르면 임의 SQL 대신 검토·clarification·block으로
+귀결될 가능성이 커진다. 다만 모델이 자연어의 숨은 필터를 아예 발견하지 못하는
+문제까지 결정론적으로 해결했다고 주장하지 않는다. 자연어 planner 정확도는
+별도 local-model 평가로 측정해야 한다.
+
+## 검증 경계
+
+```bash
+uv sync --extra duckdb
+uvx ruff check src/lang2sql tests bench/local_model_semantic_eval.py examples/semantic_runtime_quickstart.py
+uv run mypy src/lang2sql examples/semantic_runtime_quickstart.py
+env -u OPENAI_API_KEY -u LANG2SQL_LLM_BASE_URL \
+ uv run pytest -q
+```
+
+GitHub Actions는 Python 3.10과 3.12에서 DuckDB import를 필수로 확인한 뒤 같은 lint,
+type-check, 전체 테스트를 실행한다.
+
+회귀 검증에는 테스트 중 생성하는 다중 테이블 SQLite fixture와 물류·발전·교육·
+고객지원·조위 어휘 변형을 사용한다. 별도 공개 평가는 BIRD Mini-Dev와 정부·과학
+CSV에서 만든 21개 SQLite DB의 28개 case(dev 11 DB, holdout 10 DB)를 사용한다.
+17개는 typed-query 의도 범위이며 기대 결과는 exact result, 공개 정책 차단 또는
+문서화한 coverage difference로 나뉜다. 나머지 11개는 미지원 의무를 안전하게
+차단해야 하는 case다. dataset 고유 mapping과 gold SQL은 `bench/**` 밖의 제품
+코드나 모델 입력으로 나가지 않는다.
+
+oracle-plan 실행은 compiler, join, disclosure, 실제 결과 동일성을 검증한다. gold
+semantic plan을 사용하므로 자연어 planner 정확도를 증명하지 않는다. nullable FK를
+보존하는 production `LEFT JOIN`이 frozen oracle의 `INNER JOIN`보다 orphan fact를
+하나 더 보존하는 경우도 별도 coverage-policy difference로 보고하며 gold를 제품
+동작에 맞게 고치지 않는다.

-Discord에서 자연어로 질문하면 SQL을 생성하고 결과를 돌려주는 분석 에이전트입니다.
+이 문서는 Discord에서 DB를 연결하고 질문·검토·철회를 수행하는 운영 절차만 다룬다.
+설계 근거와 token/state 계약은 [`REVIEWED_SEMANTIC_QUERY.md`](REVIEWED_SEMANTIC_QUERY.md),

+처음 사용하는 관리자는 **준비 → `/setup` → 봇 멘션 → 필요한 review 승인**까지만
+먼저 읽으면 된다. 표현 mapping·공개 등급·초기화는 관리자 상세 절차에 모았다.
-## 빠른 시작
+## 준비
-봇이 서버에 있다면 바로 질문할 수 있습니다.
+실제 질문에는 tool calling이 가능한 모델이 필요하다. OpenAI를 사용하거나 Ollama
+같은 OpenAI-compatible 서버를 연결한다.

----
+## 1. `/setup`으로 DB 연결
-## 2단계: 비즈니스 용어 등록
+Discord 서버 관리자가 `/setup`을 실행하고 DB 종류와 접속 정보를 입력한다.
+지원 선택지는 SQLite, PostgreSQL, MySQL, Snowflake, BigQuery, DuckDB, D1이다.
+credential-bearing DSN을 채널 명령으로 직접 받는 `/connect`는 노출하지 않는다.
+다른 DB는 metadata scan이 가능해도, 현재 검토형 SQL 실행은 기존 file-backed
+SQLite와 DuckDB에서만 지원한다.
-"월매출", "활성고객"처럼 회사 내부 용어를 등록해두면 LLM이 SQL을 훨씬 정확하게 만듭니다.

-### 방법 A — 텍스트에서 자동 추출
+1. `/setup`
+2. `SQLite` 선택
+3. 봇 프로세스에서 접근 가능한 DB 파일의 절대 경로 입력
+4. `/semantic_status`로 연결과 검토 대기 상태 확인
-문서나 정의집 내용을 붙여넣으면 후보를 자동으로 뽑아줍니다.
+연결 성공 메시지는 테이블 수, 선언 FK 수, 민감·식별자·비지원 컬럼 차단 수와
+관리자 공개 검토가 필요한 문자열 차원 수를 보여준다. 연결 단계에서는 업무
+지표를 전부 묻지 않는다.

+
+관리자 상세: catalog 표현과 공개 범위 연결 절차
-- `accept`: `all`이면 전체, `1,3`처럼 번호를 지정하면 선택 등록
-- `layer`: `channel`(이 채널 전용), `guild`(전사 공통, 관리자 전용), `member`(개인)
+### 불투명한 분류 컬럼에 업무 표현 연결
-### 방법 B — 직접 등록
+`col_a`, `code_17`처럼 물리 이름만으로 업무 분류 의미를 알 수 없다면 관리자가
+값을 보지 않고 표현만 연결할 수 있다.
-```
-/term_custom
-```
+1. `/semantic_dimension_candidates search:<물리 컬럼 이름>`
+2. 결과의 15분 `mapping_token`과 분류 근거 확인
+3. `/semantic_dimension_map candidate_token: phrase:<업무 표현> confirm:false`
+4. 같은 관리자·토큰·표현으로 `confirm:true`
-안내에 따라 용어명, 정의, 종류(metric/rule/dimension/table)를 입력합니다.
+이 경로는 모든 비차단 dimension을 탐색하지만 값 샘플을 읽지 않고 그룹 값 공개도
+승인하지 않는다. 동일 표현이 다른 dimension에 이미 연결됐거나 이전 검토에서
+거절됐으면 차단한다. 이후 질문에서 reviewed phrase가 shortlist 근거로 재사용된다.
-### 방법 C — DB 스캔으로 자동 추출
+### 문자열 분류값 공개 승인
-```
-/org_setup org:회사명
-```
+질문에 필요한 문자열 차원이 공개 검토 대기라면 다음 순서를 따른다.
-DB 스키마를 분석해 비즈니스 용어 후보를 자동으로 뽑습니다.
+1. `/semantic_candidates search:<물리 컬럼 이름>`
+2. 결과의 15분 `candidate_token`과 분류 근거 확인
+3. `/semantic_release candidate_token:<토큰> disclosure_tier:controlled_grouped confirm:false`
+4. 경고를 읽고 같은 관리자·토큰·등급으로 `confirm:true`
----
+`controlled_grouped`는 각 결과 그룹의 실제 지표 기여 행이 5개 미만이면 전체
+결과를 차단한다. `public_grouped`가 필요하면 먼저 아래 명령으로 연결 전체가
+공개·비개인 데이터임을 확인해야 한다.
-## 3단계: 질문하기
+1. `/semantic_public_data enable:true confirm:false`
+2. 경고에 표시된 `action_token`으로 권한 있는 관리자가 `confirm:true`
+3. `/semantic_release ... disclosure_tier:public_grouped confirm:false`
+4. 같은 관리자·토큰·등급으로 `confirm:true`
-용어를 등록한 뒤 자연어로 질문합니다.
+일부 컬럼만 공개이거나 개인·조직 민감 데이터가 섞였으면 전체 공개 확인을 쓰지
+않는다. 공개 승인은 결과 라벨 표시 권한이고, 아래 질문 표현의 의미 연결과는
+서로 대체되지 않는다. 두 흐름 모두 DB 값을 후보 화면이나 LLM에 샘플링하지 않는다.
-```
-@Lang2SQL 월매출 기준 이번 달 상위 고객 10명 보여줘
-@Lang2SQL 환불제외 기준으로 채널별 주문 수 알려줘
-```
+### 불투명한 수치 컬럼에 업무 표현 연결
-봇이 SQL을 생성해 실행하고 결과를 표시합니다.
+물리 이름만으로 지표를 좁힐 수 없다면 관리자가 다음 순서로 표현만 연결한다.
----
+1. `/semantic_metric_candidates search:<물리 컬럼 이름>`
+2. 결과의 15분 `candidate_token` 확인
+3. `/semantic_metric_map candidate_token:<토큰> phrase:<업무 표현> confirm:false`
+4. 같은 관리자·토큰·표현으로 `confirm:true`
-## 용어 우선순위 (Federation)
+이 명령은 표현과 수치 컬럼만 연결한다. `SUM`/`AVG` 같은 집계 의미는 실제 질문의
+`/semantic_review`에서 별도로 확인한다.
-같은 용어가 여러 레이어에 등록된 경우 **좁은 범위가 우선** 적용됩니다.
+
+## 2. 봇을 멘션해 질문
+
+```text
+@Lang2SQL Amount by region name
```
-개인(member) > 채널(channel) > 전사(guild)
-```
-예를 들어 "활성고객"을 전사에서는 "30일 내 로그인"으로 정의했더라도, 마케팅 채널에서 "14일 내 로그인"으로 따로 등록하면 마케팅 채널 안에서만 그 정의가 우선 적용됩니다. 다른 채널에는 영향이 없습니다.
+명시적 `@Lang2SQL` 멘션이 필요하다. 봇은 일반 대화, `@everyone`, `@here`를
+질의로 가로채지 않는다. DM은 사용자별로 격리되어 허용된다. Discord 서버에서는
+관리자 또는 `LANG2SQL_DISCORD_QUERY_CHANNEL_IDS`에 등록된 상위 채널의 구성원만
+질문할 수 있다.
+
+처음 보는 질문은 지표와 분류 표현이 독립 검토로 나뉠 수 있다. 예를 들어 지표
+집계를 먼저 확인한 뒤, 같은 질문의 분류 표현 연결을 한 번 더 확인할 수 있다.
+관리자는 `/semantic_reviews`에서 정확한 `review_id`를 복사하고 다음처럼 처리한다.
+
+```text
+/semantic_review review_id: aggregate:sum
+/semantic_review review_id:<다음 ID> aggregate:confirm
+```
----
+대기열에는 원 질문·필터 값·날짜 경계를 저장하지 않는다. 봇 프로세스가 그대로면
+승인 후 같은 typed draft를 자동 재개하고, 재시작된 경우에는 승인은 저장하되 원
+요청자에게 같은 질문을 다시 보내도록 안내한다.
-## 전체 커맨드 목록
+선택 가능한 값은 해당 검토 항목에 따라 `sum`, `avg`, `min`, `max`, `count`,
+`confirm`, `reject` 중 일부다. 숫자 컬럼에는 `SUM`/`AVG`/`MIN`/`MAX`가 쓰이고,
+`COUNT`는 물리 테이블의 source-record count에만 쓰인다.
-| 커맨드 | 설명 |
-|---|---|
-| `/setup` | DB 연결 마법사 (관리자) |
-| `/connect dsn:...` | DSN으로 직접 DB 연결 |
-| `/ingest content:...` | 텍스트에서 용어 후보 추출 |
-| `/ingest ref:파일명` | 서버 파일에서 용어 후보 추출 |
-| `/confirm_ingest ref:... accept:... layer:...` | 추출된 후보 검토 후 등록 |
-| `/term_custom` | 용어 직접 등록 (위저드) |
-| `/term_custom action:show` | 등록된 용어 전체 조회 |
-| `/term_custom action:remove term:용어명` | 용어 삭제 |
-| `/org_setup org:...` | 전사 조직 등록 + DB 스캔 |

-| `/enrich` | DB 컬럼 메타데이터 자동 보강 |
-| `/remember text:...` | 사실 기억 저장 |
-| `/audit_me` | 내 활동 이력 조회 |
+승인에는 당시의 질문·연결 세대·catalog revision·지표·집계·분류가 함께 묶인다.
+원 요청자가 직접 승인한 경우에는 원래 질문을 LLM 재해석 없이 재개한다. 관리자가
+다른 사용자의 검토를 승인한 경우에는 연결만 저장하고 관리자 채널에서 DB 결과를
+실행하거나 표시하지 않는다. 원 요청자가 같은 질문을 다시 보내야 한다.
----
+## 3. 상태, 철회, 초기화
-## 자주 묻는 질문
+- `/semantic_status`: 자동 구조와 확인된 표현·집계·공개 정책 상태 확인
+- `/semantic_candidates`: 문자열 차원 후보 검색 및 15분 토큰 발급(관리자)
+- `/semantic_dimension_candidates`: 모든 비차단 분류 차원과 mapping token 검색(관리자)
+- `/semantic_dimension_map`: 불투명한 분류 컬럼에 업무 표현만 연결(관리자)
+- `/semantic_metric_candidates`: 수치 지표 후보 검색 및 15분 토큰 발급(관리자)
+- `/semantic_reviews`: 현재 연결의 의미 검토 대기열(관리자)
+- `/semantic_candidates state:released search:...`의 별도 `revoke_token`을 복사해
+ `/semantic_revoke candidate_token:... confirm:false` → 같은 토큰으로 `confirm:true`
+- `/semantic_public_data enable:false confirm:false` → 발급된 `action_token`으로 `confirm:true`
+- `/semantic_reset confirm:false` → 발급된 `action_token`으로 `confirm:true`
-**Q. 질문했는데 엉뚱한 SQL이 나와요.**
-등록된 용어가 없거나 DB 메타데이터가 부족한 경우입니다. `/enrich`로 컬럼 설명을 보강하거나 `/term_custom`으로 관련 용어를 등록해보세요.
+모든 관리자 후보·행동 토큰은 15분 동안 현재 source, 연결 세대, 행동 종류와
+검토 대상에 묶인다. 연결이나 관련 상태가 바뀌었거나 token이 만료되면 후보 조회
+또는 경고 단계부터 다시 시작한다. 정확한 binding 필드는
+[`안전 경계`](REVIEWED_SEMANTIC_QUERY.md#안전-경계)에 정의돼 있다.
+`/semantic_reset`은 사람이 확인한 표현·집계 연결, 문자열 공개 승인, 공개 데이터
+범위를 함께 초기화하지만 물리 PK/FK와 기본 차단 정책은 제거하지 않는다.
+실행 중 revoke/reset/재연결이 발생하면 실행 후, audit 후, Discord 렌더 직전의
+catalog stamp 재검사에서 준비된 결과를 폐기한다.
-**Q. "guild 용어는 관리자만 등록 가능" 오류가 나요.**
-`layer:guild`는 관리자 권한이 필요합니다. `layer:channel`로 채널 범위로 등록하거나 관리자에게 요청하세요.
+## 현재 질의 및 공개 정책
+
+지원:
-**Q. 이전 대화 내용을 기억하나요?**
-같은 채널(또는 DM 스레드)에서 이어지는 대화는 맥락이 유지됩니다. `/remember`로 중요한 사실을 명시적으로 저장할 수도 있습니다.
+- 숫자 컬럼의 표현별 `SUM`/`AVG`; `MIN`/`MAX`는 공개 데이터 범위에서만 지원
+- 모든 테이블의 명시적 physical source-record `COUNT(*)` (PK 불필요)
+- categorical group-by
+- 선언 FK의 유일한 child-to-parent 1~N hop join
+- nullable FK나 orphan fact를 보존하는 `LEFT JOIN`
+- 명시적 AND 최대 8개의 exact `EQ` 또는 값 최대 20개의 `IN` bound filter
+- native `DATE` 차원의 ISO date `[start, end)` 기간창
+- 기존 file-backed SQLite와 DuckDB의 read-only governed execution
+
+비공개 기본값에서는 그룹 유무와 무관하게 `SUM`/`AVG`/source-record `COUNT`의
+실제 기여 행이 5개 미만이면 결과 전체를 차단하고, 단일 극값을 드러내는
+`MIN`/`MAX`는 실행하지 않는다. 공개 데이터 범위에서도 하나라도
+`controlled_grouped` 차원을 사용하면 이 보호가 유지된다. `public_grouped`는 최소
+그룹 보호를 해제하지만 최대 50범주와 라벨 128자 제한은 유지한다. 이 숫자는
+출력 억제 규칙일 뿐 k-anonymity 보장이나 사용자 권한 부여가 아니다.
+
+차단 또는 추가 확인:
+
+- raw SQL, row projection, OR/NOT, 부분 문자열·자유 filter와 계산식
+- timestamp timezone, relative time, fiscal/cohort 기간 기준
+- 단위 변환
+- composite FK, parent-to-child fan-out, 동률 join path
+- PII, credential-like, 서술문, 식별자형 문자열 컬럼
+- 관리자 공개 승인을 받지 않은 불확실한 문자열 차원
+
+미지원 조건을 버린 채 결과를 내지 않는다. 조건이 남으면 `NEEDS CLARIFICATION`
+또는 `BLOCKED`로 끝난다. 현재 실제 안전 실행 증거는 existing file-backed SQLite와
+DuckDB에 한정된다. 다른 DB 커넥터는 연결 가능성과 timeout/취소가 검증된 질의 실행
+범위를 구분하며, 검증되지 않은 원격 dialect의 governed 실행은 차단한다.
+
+### 막혔을 때 무엇을 해야 하나
+
+| 화면 또는 코드 | 의미 | 다음 행동 |
+|---|---|---|
+| `NEEDS CLARIFICATION` | 질문의 지표·분류·필터·기간을 현재 후보만으로 확정할 수 없음 | 안내된 항목을 구체적으로 다시 질문하거나 관리자가 표현을 연결 |
+| `ReviewRequired` / `/semantic_reviews` | 업무 의미 또는 공개 범위를 사람이 확인해야 함 | 허용된 선택지 중 하나를 승인·거절한 뒤 원 요청자가 질문 재개 |
+| 토큰 만료 또는 stale source | 15분 검토 토큰이 만료됐거나 DB가 재연결됨 | 후보 조회 또는 경고 단계부터 새 토큰 발급 |
+| `BLOCKED`와 unsupported obligation | 현재 typed plan이 지원하지 않는 조건이 있음 | 조건을 제거하지 말고 지원 범위를 확장하거나 다른 분석 경로 선택 |
+| contributor·disclosure 차단 | 결과가 너무 작거나 차원이 아직 공개되지 않음 | 데이터 공개 정책을 확인하고, 허용되는 경우에만 관리자 검토 |
+| catalog/audit 오류 | 의미 변경이나 실행을 안전하게 기록할 수 없음 | 저장소 오류를 복구한 뒤 새 plan으로 다시 시도 |
+
+차단 사유를 무시하고 `run_sql`로 우회하는 것은 연결 즉시 의미 준비형 질의 모드의 복구
+방법이 아니다.
+
+## 기타 기존 명령
+
+`/ingest`, `/confirm_ingest`, `/term_custom`, `/remember`, `/audit_me`는 기존
+기능으로 남아 있다. `/enrich`와 `/org_setup`의 raw-value sampling은 연결 즉시
+의미 준비형 질의가 활성화된 DB에서는 의도적으로 비활성화된다.

# Lang2SQL v4.1 — 컨셉과 아키텍처
+> **역사적 설계 문서**: 아래 명령 표는 2026-05 계획 당시의 walking skeleton이다.
+> 현재 실행 표면은 [`USAGE.md`](./USAGE.md)와
+> [`REVIEWED_SEMANTIC_QUERY.md`](./REVIEWED_SEMANTIC_QUERY.md)를 따른다. 현재
+> Discord에는 raw DSN `/connect`가 없고 `/setup`을 사용한다.
+
> **작성일**: 2026-05-18
> **결정자**: ryan@brain-crew.com
> **상태**: v4 → v4.1. 두 가지 큰 정정 — (a) Discord 를 *기둥* 에서 *Phase 1 인터페이스* 로 격하, (b) **시멘틱 federation (git-like 분기)** 을 4번째 ★ 패턴으로 추가.
