UI smoke는 고정 Node/Next 실행 파일과 인자, localhost:3001 allowlist, private `mkdtemp` artifact 디렉터리 및 containment 검사만 사용합니다. diff --git a/backend/api/tools.py b/backend/api/tools.py index eafbaaf76..c11c48269

This is a precision/recall +trade-off, not an oversight, and the rejected alternative is grounded in the +conversation-threading literature: + +- Content- and coherence-model approaches to thread reconstruction are + probabilistic and improve *recall* on broken reference chains, but carry an + inherent false-merge (precision) cost: Mohiuddin, Joty, and Nguyen (2018) + reconstruct thread trees by scoring candidate structures with a neural + coherence model, and even their best model reaches only ~30% thread-level + reconstruction accuracy — useful for recall on missing links, but far from the + certainty a mailbox view requires. +- Email threads are also large and topically heterogeneous in practice (Kooti, + Aiello, Grbovic, Lerman, & Mantrach, 2015, characterize replying behavior + over 16 billion messages; Zhang, Celikyilmaz, Gao, & Bansal, 2021, curate + 2,549 real email threads for EmailSum), so a wrong content-based merge is both + likely and costly at scale. +- Naruon therefore optimizes for *precision* — never merging unrelated messages — + because a wrong merge silently corrupts a user's mailbox view. The invariant is + pinned by `test_forwarded_subject_alone_does_not_merge_unrelated_thread`. +- The #1192 In-Reply-To fix improves *recall on the header-complete path* (it + no longer drops multi-parent / CFWS replies) with **zero** precision cost, + because it stays entirely within the deterministic header graph. + +The cited papers are bookmarked in the shared alphaXiv library folder +"CWL · Naruon email/threading standards grounding". + +## References (APA 7) + +- Resnick, P.

It also ensures the correct `ExecuteResponse.model_json_schema()` usage in the openapi tests. Only backend/api/tools.py, backend/tests/test_tools_api.py, and CHANGELOG.md have been modified.
