How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

| ## 2026-08-07 - Optimize string-based node lookups using handle decoding | ||
| **Learning:** We can reduce (N)$ string encoding loops in FK edge column lookups to (1)$ directly by decoding the parsed handle id to extract column names directly without generating garbage. | ||
| **Action:** Always parse handles directly to resolve elements in edge loops if possible, rather than scanning the node lists to string encode. |

컬럼 존재 확인이 선형 탐색이므로 O(1) 조회 목표를 충족하지 못합니다.
핸들 디코딩은 O(1)입니다. 그러나 각 엣지에서 .some으로 컬럼을 검사하므로 전체 FK 컬럼 조회는 계속 O(C)입니다.

빈 컬럼명이 있는 핸들을 유효하게 처리하십시오.
parseColumnNameFromHandle('src-c-empty')는 ''를 반환합니다. Line 77과 Line 83은 빈 문자열을 거짓으로 처리합니다. 따라서 지원하는 c-empty 핸들은 FK 컬럼 해석에 실패하고 fallback으로 이동합니다.
parsedSource !== null 및 parsedTarget !== null로 검사하십시오. 최종 컬럼 존재 검사에는 !== undefined를 사용하십시오. c-empty 핸들과 fallback 동작을 검증하는 fkColumnsForEdge 테스트를 추가하십시오.

잘못된 16진수 토큰을 명시적으로 거부하십시오.
parseInt(hex, 16)은 첫 번째 비-16진수 문자 뒤의 값을 무시합니다. 따라서 src-c-0069junk-0064는 id로 디코딩됩니다. frontend/src/erd/export.ts는 이 값을 실제 컬럼명으로 승인할 수 있습니다.
각 토큰을 디코딩 전에 16진수 코드포인트 형식으로 검증하십시오. src-c-0069junk-0064가 null을 반환하는 테스트도 추가하십시오.

💡 What: Replaced an O(N) array iteration with an O(1) handle parsing utility (
parseColumnNameFromHandle) infkColumnsForEdge.🎯 Why: Finding connected columns for foreign key edges involved iterating over all columns and re-encoding their names just to match the edge handle. This resulted in O(N^2) complexity over diagram sizes, leading to wasted string allocations and CPU cycles.
📊 Impact: Reduced FK lookup complexity per edge from O(C) to O(1), cutting string allocations during graph exports and UI updates.
🔬 Measurement: Verify tests run completely in less time (
pnpm testsuccessfully completed infrontend). Review logic infrontend/src/erd/export.tsensuring the correct source and target columns are selected.PR created automatically by Jules for task 14142744112914767576 started by @seonghobae
