Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change preserves quoted PostgreSQL identifiers, but relationships for identically named tables in different schemas can still be associated with the wrong table because schema-qualified identity is not retained during lookup. This could silently create incorrect ERD relationships, so the schema-collision case should be resolved or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

| - [BE] 🔒 **Cryptography 50+ 보안 경계 갱신**: `pyproject.toml`과 두 hash-locked 요구사항 파일을 동일한 Cryptography 50+ 해석으로 정합화하여 PKCS#7 오류·타이밍 구분으로 인한 CVE-2026-69247 완화를 실제 설치·검증 경로에 반영했습니다. | ||
| - [FE] 🧭 **관계 추론의 PostgreSQL 식별자 보존**: 자동 관계 추론은 snapshot의 정확한 `relation_name`을 사용하고 ASCII allowlist나 마지막 점 구간으로 식별자를 다시 쓰지 않습니다. 따라서 공백·대소문자 혼합·Unicode·점이 포함된 quoted relation 이름도 손실 없이 연결되며, 모호한 trailing-segment 별칭이 잘못된 테이블을 선택하지 않는 회귀 테스트로 고정했습니다. |

🟡 Frontend changelog not updated for user-visible change
CLAUDE.md requires user-visible frontend changes to be recorded in both CHANGELOG.md and frontend/CHANGELOG.md. This PR adds the [FE] inference-fidelity entry only to the root file, leaving frontend/CHANGELOG.md untouched.
Prompt for agents
CLAUDE.md documents the convention that user-visible frontend changes must be recorded in both CHANGELOG.md (Korean) and frontend/CHANGELOG.md. This PR adds a new [FE] entry for the PostgreSQL relation-identity inference fix to the root CHANGELOG.md but does not add a matching entry to frontend/CHANGELOG.md. Add an equivalent entry under the [Unreleased] section of frontend/CHANGELOG.md to keep the two changelogs in sync.

📝 Info: Fallback identity differs for multi-dot titles
For nodes without relation_name, the fallback in relationName keys on everything after the first dot rather than the last segment, so a title like public.Order.Items now yields Order.Items instead of Items. Snapshot nodes always set relation_name so are unaffected; only hand-built nodes with multi-dot titles change behavior.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
동일한 relation_name을 가진 서로 다른 schema를 모호하게 연결하지 마십시오.
relation_name만 Map 키로 사용하므로 public.users와 audit.users는 모두 "users" 키를 사용합니다. Line 30은 두 번째 node를 무시합니다. 이후 users_id는 입력 순서에 따라 첫 번째 node로 inferred edge를 만듭니다.
PostgreSQL은 서로 다른 schema에 같은 객체 이름을 허용합니다. (postgresql.org)
schema-qualified identity를 전달하여 조회하거나, 같은 relation_name 후보가 둘 이상이면 inferred edge 생성을 건너뛰십시오. 이 경우를 검증하는 회귀 테스트도 추가하십시오.

snapshotToGraph의 relation_name 전파를 검증하는 테스트를 추가하십시오.
새 회귀 테스트는 tableNode에서 relation_name을 직접 설정합니다. 따라서 snapshotToGraph가 snapshot 값의 Unicode, 공백, 대소문자, 점을 포함한 이름을 node data로 전달하는 계약은 검증하지 않습니다.
SnapshotJson 입력과 생성된 node data를 비교하는 focused test를 추가하십시오.
As per coding guidelines, **/*.{py,ts,tsx}: Add or update focused tests when changing behavior.

Buyer impact
ERD relationship inference could silently miss or mis-route relationships for valid PostgreSQL quoted identifiers containing Unicode, spaces, mixed case, or periods. In particular, a relation such as
Order.Itemsmust remain distinct fromItems.Scope
This is a clean replacement for the stale/polluted #774 lane, rebuilt directly from protected
main@8dc746920c12988f082e914879d95e13c9693535so unrelated workflow, dependency, Docker, coverage, and security drift is not carried forward.relation_nameintoTableNodeDatasanitizeTableNamehelper from this non-SQL boundaryOrder.ItemsvsItemsambiguityDesign boundary
This changes identifier fidelity inside ERD relation inference; it does not introduce or alter a reusable visual component. Current protected
mainhas no Storybook scripts, and the live Figma file currently exposes only itsCoverpage, so no visual design artifact is claimed as executable evidence for this bounded behavior repair.Validation contract
