Merge Risk: 🟡 Moderate · up to The new overflow-recovery logic is designed to cap automatic conversation remints at three per conversation to avoid masking repeated context-overflow failures, but for conversation-only clients and one thread-identification variant, the cap resets every time a remint succeeds. In practice this means some users could see unlimited silent conversation remints instead of the intended bounded retry behavior, which should be fixed before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Keep the overflow-remint scope stable across turns. src/adapters/cursor.ts:403-412 replaces the conversation ID during remintConversationId, but overflowRemintBaseId remains scoped to the current request. The next turn therefore uses the reminted ID as a new key and can receive another first overflow plus three remints.
cursorClientThreadOwner in src/adapters/cursor/request-builder.ts:343-365 treats _cursorClientThreadId as a thread owner, and src/adapters/cursor.ts:416-422 persists continuity for it. However, cursorOverflowRemintScopeKey in src/adapters/cursor/thread-continuity.ts:115-128 checks only _clientThreadId, so _cursorClientThreadId clients also use the unstable conversation branch.
Use the shared thread-owner semantics in cursorOverflowRemintScopeKey, and persist and reuse the original conversation base across remints for conversation-only clients. Add regression coverage for both client types.

리뷰 · 우선순위 71 / 80이 PR은 Cursor Connect 전송에서 맨 처음 걸린 맨손 동작은 짧습니다. 이 방향은 점수 71인 이유: Cursor 어댑터 실사용 안정성에 바로 닿고, L1/L5 레인과 충돌하지 않으며 준비 상태도 좋습니다. 다만 일곱 레인 첫 구현 자체는 아니고, #3506(Cursor/Grok 무진행 루프)과는 실패 종류가 다릅니다. 이 PR은 컨텍스트 한계 overflow 신호·복구이지, 같은 체크포인트를 반복만 하는 루프 감독이 아닙니다. 그 이슈를 닫는다고 쓰면 안 됩니다. 운영 감각 한 줄: 첫 오버플로 뒤 클라이언트가 줄이지 않은 채 같은 큰 페이로드를 다시 내면 remint 예산(3)이 빨리 닳고 이후 에러가 그대로 올라갑니다. 의도된 fail-closed에 가깝습니다. echo/commentary 가드 재시도 갈래에서 재시도가 다시 throw하면 그 예외는 overflow remint 루프에 재진입하지 않고 밖으로 나갑니다. 라인 427 - 메인테이너의 판단이 필요한 지점

Reviewed the overflow-loop/accounting changes at 34bbcaf. The first overflow is surfaced before remint, quota/rate cues remain outside this recovery path, and the retry guards retain tool-result, already-emitted-output, side-effect and compaction exclusions. This is not a fix for #3506's no-progress loop.
Please add adapter-level coverage for the conversation-only scope branch (without _clientThreadId). The new surface/remint/cap tests all supply a thread id, although the scope helper explicitly supports a base conversation id that is replaced during remint. Verify the intended cap across a successful remint and the next request's persisted conversation id, not only several retries inside one runTurn. Document whether the three-remint allowance is per stable logical owner or resets when that conversation-only id changes; do not claim a stronger lifetime cap than the stored identity establishes.
The current source is a candidate, but exact-head full runtime/typecheck evidence and the conversation-only continuation contract remain to be established. No live Cursor request, local session mutation, or merge was performed.
