Pydantic 문자열 필드(DiagramViewCreateIn.name 등)에 제어 문자가 입력되는 것을 방지하기 위해 정규식(pattern=r"^[^\x00-\x1F\x7F]+$")을 추가했습니다. 이를 통해 로그 인젝션 및 널 바이트 인젝션 공격을 예방합니다.

Understood. Acknowledging that this work is now obsolete and stopping work on this task. |

Fresh current-head review found a domain-contract problem in the proposed The PR's MEDIUM log-injection rationale also has no demonstrated logging sink for these fields in the current source. Input-domain restriction is not a substitute for output/log encoding, and it must not corrupt database identity just to protect a hypothetical sink. Required repair on exact head RED: add a regression showing a table annotation can preserve a valid quoted-identifier-shaped schema/relation containing a non-NUL control character (for example LF/TAB) without normalization; keep multiline annotation body behavior. GREEN: remove the blanket C0/DEL pattern from the database-identity fields, or replace it only with a domain rule justified by the actual supported database identity contract. If log/terminal injection is real, demonstrate the concrete sink and fix escaping/structured logging at that sink. Do not merge the current broad filter as a security fix; it trades an unproven log-injection claim for a standards-incompatible identity regression. |

Repaired exact head in place according to requirements. 1. Added a test ( |
- Remove blanket control character filtering from `TableAnnotationUpsertIn` schema/relation name fields to satisfy PostgreSQL's lexical contract (which allows LF, TAB, etc. in quoted identifiers). - Maintain control character filtering on product label schemas like `DiagramViewCreateIn.name`. - Add regression test `test_table_annotation_postgres_identity.py` to assert correct behavior. - Update `docs/product-technical-gap-baseline.md` and `.jules/sentinel.md` to document the domain exception and advise fixing log injection at the sink for database identifiers.

Current finding
The branch originally treated product labels and PostgreSQL table identity as one control-character domain and described the change as a generic log-injection fix. Fresh review split those contracts and repaired the database-identity regression.
DiagramViewCreateIn.nameandApiKeyCreateIn.key_nameare product labels and reject ASCII C0/DEL.TableAnnotationUpsertIn.schema_nameandrelation_nameare PostgreSQL database identities: they now reject only NUL while preserving LF/TAB and other characters permitted in quoted identifiers.TableAnnotationUpsertIn.bodykeeps multiline content. No hypothetical logging sink is used to narrow the database identity contract; any concrete sink defect must be fixed at the sink.Authoritative reference: PostgreSQL lexical structure, quoted identifiers: https://www.postgresql.org/docs/19/sql-syntax-lexical.html
