fix: harden knowledge provenance and improve retrieval reliability

[nalbam]

출처를 보관하거나 공유 범위를 줄인 뒤에도 Graph의 이름·속성·vector가 검색과 응답에 남는 문제를 출처별 저장·조회 계약으로 해결합니다. 공개 이름으로만 identity를 해석하고, 기존 노드 ID와 새 출처의 기여 내용을 분리합니다.

• Clean Architecture의 node/edge 쓰기 모델과 조회 모델을 분리하고 중복 scope·관계 정책, 사용하지 않는 컬럼·index·UI 분기를 정리했습니다.
• 같은 출처의 수동 속성 snapshot은 명시적으로 교체하고 AI 승인은 수동 속성·승인된 endpoint를 보존하고, 새 embedding이 없는 재기여는 기존 vector/model을 유지합니다. 문서 범위 변경을 일괄 거부하던 우회 경로를 제거했습니다.
• 설정 캐시 동시 miss의 DB 조회를 20회에서 1회로 줄이고, queue 부분 시작 실패 자원을 회수하고 실제 DB 연결 종료까지 기다리며, CSV 원문 좌표와 평가 언어 설정을 바로잡았습니다.
• Memory 이력을 필요할 때 페이지 단위로 조회하고 접근 오류 후 첫 페이지부터 복구하며, 회원 변경 이후 늦은 응답이 화면을 되돌리지 않도록 했습니다.
• 저장소 전체 파일을 검토하고 공개 API·운영·사용자 문서를 현재 구현과 맞췄습니다.

검증: 동일 HEAD의 GitHub CI 통과

• pnpm verify: schema SQL 일치, lint, typecheck, architecture, 단위 테스트 616개, production build 통과
• pnpm test:integration: PostgreSQL·Neo4j 통합 테스트 112개 통과
• E2E_AUTHENTICATED=true pnpm test:e2e: 전용 DB에서 인증 E2E 16개 통과
• 현재 파일 467개의 검토 기록·SHA-256 일치, 문서 링크·앵커 102개 확인
• 직접 의존성의 사용처와 lockfile 912개 package/snapshot·1869개 연결의 정합성 확인

32출처 × 4096차원의 동일 PostgreSQL fixture에서 불필요한 vector hydration을 제거해 조회 결과 JSON을 1,395,223 → 13,559 bytes(99.03%)로 줄였습니다. 공개 조회 결과·의미 검색 점수·병합 시 vector 보존을 함께 검증했습니다.

배포 주의: schema가 변경됩니다. 기존 DB는 자동 변환하지 않으며 배포 전에 백업·보존 범위와 별도 초기화 승인이 필요합니다. 운영 데이터 변경이나 rollout은 수행하지 않았습니다.

기존 Dependabot 경고도 확인했습니다. 평가용 nltk==3.10.3의 GHSA-8mgp-746c-j5xp는 공식 권고에 수정 버전이 없습니다. 이 저장소는 해당 모델 파일 저장·로드 API나 pathsec를 사용하지 않고 평가 코드·Python 의존성을 application image에서 제외합니다. 현재 HTTP/MCP 실행 경로에는 해당 취약점의 실행 조건이 없으며, 경고는 해제하지 않았습니다.

📝 Walkthrough

Walkthrough

The changes move Knowledge identity, properties, descriptions, and embeddings to source-level records. They also update document scope changes, CSV chunk offsets, memory history, member-list refreshes, extraction language, and deployment guidance.

Changes

Source-scoped Knowledge

Layer / File(s)	Summary
Source data contracts database/schema.sql, src/infrastructure/database/schema/knowledge-graph.ts, src/domain/knowledge/*	Node and edge data now use source contributions. Source records store properties, names, embeddings, and update times.
Visible identity and persistence src/infrastructure/database/repositories/*knowledge*, src/domain/knowledge/*	Reads use readable source metadata. Identity resolution uses primary names. Search uses visible names, descriptions, and compatible source embeddings.
Validation and documentation tests/knowledge-*.integration.test.ts, tests/database-schema.integration.test.ts, docs/api.md, docs/architecture.md	Tests and documentation cover source visibility, provenance merging, identity resolution, and vector search.

Document and application flows

Layer / File(s)	Summary
Document scope and CSV chunking src/application/document/*, src/infrastructure/database/repositories/document-scope-change-repository.ts, tests/document-*, e2e/document-scope.spec.ts	Related-knowledge scope conflicts no longer reject scope changes. CSV chunks retain normalized record offsets and header context.
Memory history src/app/memory-*, src/app/api-response-schemas.ts, e2e/memory-history.spec.ts	History loads on demand in pages of 25 with retry, unavailable states, and load-more behavior.
Member refresh src/app/members/member-management.tsx, e2e/member-refresh.spec.ts	Active member and team requests are cancellable. Stale responses do not update the view.

Evaluation, UI, and operations

Layer / File(s)	Summary
Configured extraction language evaluation/knowledge/*, docs/operations.md, docs/getting-started.md, tests/knowledge-evaluation-cli.test.ts	Extraction uses configured languages. Reports and reuse metadata include language.
Search actions and styling src/app/search-console.tsx, src/app/_i18n/messages/*, src/app/*module.css	Document archive actions and related messages are removed. Graph actions remain.
Runtime and deployment support README.md, docs/operations.md, src/lib/runtime-settings.ts, src/infrastructure/queue/document-ingestion-queue.ts	Deployment guidance separates alpha and production promotion. Concurrent settings reads share a request. Queue startup failures use cleanup handling.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~90 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to c6a59

No merge-blocking issue was found in the supplied context. The schema change still needs a backup and a separate initialization approval before deployment, as the PR description states.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c6a59

The inspected flows retain authorization and derive returned knowledge from currently visible sources. No introduced security bypass was established. Deployment still requires an approved database preparation procedure, and incomplete coverage of other changed flows prevents treating the overall change as risk-free.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The inspected search and merge paths operate within the authenticated caller's organization. Merge additionally requires current management authority over both nodes and matching scopes. The reviewed paths do not establish exposure across organizations, deployment environments or shared infrastructure services.

Security Findings and Attack Paths

• inferred — The suspected path from unfiltered internal lookups to disclosure through merge was not substantiated. Merge preserves memory or chunk identifiers when transferring even unavailable contributions, then projects its response using current source visibility. Preserving hidden provenance therefore does not by itself make that provenance publicly visible.

Trust Boundaries and Controls

• observed — Caller-supplied node creation data passes scope-write authorization and source authorization before persistence. Persistence resolves identity from accessible names under a write lock and separately filters the returned contributions. This separates authority to contribute from authority to read every contribution attached to an existing node.

Resilience and Maintainability Implications

• observed — Document archival updates document status without acquiring the shared knowledge-scope lock in the inspected repository method. Retrieval visibility independently requires a ready document, so the control is not physical deletion of provenance. The complete concurrency relationship between archival and every changed mutation remains outside the verified coverage.

지적

1. Warning — src/infrastructure/database/repositories/knowledge-node-persistence.ts:187-189 — 같은 출처의 기존 embedding을 지웁니다.
   출처 row가 이미 있을 때 embedding과 embeddingModel을 무조건 excluded 값으로 덮어씁니다. 따라서 기존 vector가 있는 node에 embedding 없이 수동 재기여하거나 AI 후보를 승인하면, propertyWrite가 "preserve"여도 해당 vector가 NULL로 바뀝니다. 이전 구현은 새 embedding이 없으면 기존 값을 유지했으므로, 그 출처에 의존하던 의미 검색이 회귀합니다. 수정 방향: 새 embedding이 없을 때는 기존 vector·model을 유지하고, vector를 명시적으로 제거하는 동작이 필요하다면 별도 입력으로 구분해 주세요.
