Successor tracking

The complete delta at this PR's head cafdc7c7b381e9b3d22ea0b8b34de49b39a2ae0b is preserved in trusted-branch successor #1067 at 1481c595dc1d16e7bf4b65addaf0bd30322cf2b8. Commit ancestry and tree equality are recorded in docs/product-technical-gap-baseline.md. Review and required-workflow integration continue there. This PR remains open until protected delivery and a fresh full-delta audit; later changes here must also be carried forward.

Summary

  • define the measured unit as a versioned deployment candidate, not an intrinsic LLM ability
  • keep unvalidated two-neighbor interpolation disabled in live routing while retaining it in the held-out experiment
  • bind persisted psychometric rows to the complete declared candidate configuration and reject overflowed similarity evidence
  • record invariance, scale-linking, local-dependence, DIF, uncertainty, judge-effect, and adaptive-exposure gates
  • inventory every supported scholarly identifier referenced by tracked Python and Markdown, with a regression contract that rejects future omissions

Evidence

  • uv run --python 3.12 python -m pytest tests/test_psychometric_routing.py tests/test_paper_contracts.py tests/test_measured_routing_evidence.py -q — 53 passed
  • uv run --python 3.12 python scripts/benchmark_psychometric_heldout.py — expected Brier 0.1418346845, log loss 0.4475784303, regret 0.0; experimental interpolation explicitly enabled
  • python -m compileall on changed Python files
  • git diff --check

Stack

Depends on #1058, #1059, and #1061 in that order. GitHub cannot use the fork-only #1061 head as a new upstream PR base, so this PR temporarily targets main and carries the cumulative stack. Do not merge it ahead of its parents. After the parents merge, the remaining diff is this validity-boundary and paper-inventory delta.

No production policy change is authorized; buyer-held-out and protected-main validity evidence remain explicitly open.

📝 Walkthrough

Walkthrough

심리측정 관찰을 배포 구성과 역할 정책에 바인딩했습니다. 선택적 semantic warm start 보간, 안전한 코사인 계산, 관찰 정리, held-out 및 성능 벤치마크, 연구 자료 인벤토리 검증을 추가했습니다.

Changes

심리측정 라우팅 증거

Layer / File(s) Summary
후보 식별자와 증거 수명주기
contextual_orchestrator/orchestrator.py, tests/test_psychometric_routing.py
후보 식별자가 배포 설정과 역할 노력 카탈로그 해시를 포함합니다. 상태 재로드, 후보 변경, 멤버 제거 시 현재 후보가 아닌 관찰을 제거합니다. 관련 재시작 및 구성 변경 테스트를 추가했습니다.
라우팅 증거 계산과 안전성
contextual_orchestrator/psychometric_routing.py, tests/test_psychometric_routing.py, CHANGELOG.md
semantic_warm_start_enabled가 활성화되면 최대 두 개의 양수 코사인 이웃 점수를 보간합니다. 기본 동작은 단일 최근접 이웃입니다. 비유한 임베딩을 거부하고 관찰 정리와 코사인 계산을 변경했습니다.
벤치마크와 측정 계약
scripts/benchmark_psychometric_*.py, docs/doctoring/measured-routing-evidence.md, docs/planning/adrs/0034-anti-heuristic-routing-evidence.md, docs/product-technical-gap-baseline.md, CHANGELOG.md
라우팅 적합·순위·관찰 지연시간과 held-out Brier score, log loss, top-choice regret, 결정 지연시간을 측정하는 스크립트를 추가했습니다. 운영 기본값과 검증 게이트를 문서화했습니다.
연구 자료 인벤토리 검증
docs/papers/README.md, tests/test_paper_contracts.py
연구 자료 인벤토리와 참고문헌을 확장했습니다. 저장소의 Python 및 Markdown 파일에서 학술 식별자를 추출하고 인벤토리 포함 여부를 검사합니다.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 61bb6

The change improves routing-evidence isolation and validation, but concurrent configuration or retention activity can cause a completed routed request to fail or discard newly collected evidence. The research-inventory test can also fail because of unrelated local generated files. These issues should be corrected before merge.

7049-7064: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

동시 배포 변경 시 next() 조회가 처리되지 않은 StopIteration을 일으킬 수 있습니다.

_observe_contextual_qualityself._psychometric_router.observe(...)를 호출한 뒤, 별도의 잠금 구간에서 self._psychometric_router.records()를 다시 조회합니다. 두 호출 사이에 경쟁 조건이 존재합니다.

다른 스레드가 같은 에이전트에 대해 patch_agent를 호출하면 후보 식별자가 바뀝니다. 그러면 _retain_psychometric_candidates가 방금 기록한 관찰을 제거합니다. 컨텍스트 캐시가 max_contexts를 초과해 LRU 축출이 일어나도 같은 결과가 나옵니다.

두 경우 모두 next(...)는 기본값이 없습니다. 따라서 항목을 찾지 못하면 StopIteration이 발생합니다. 이 예외는 _realtime_route_judge를 거쳐 route_once, stream_route, conduct 요청 처리로 전파됩니다. 결과적으로 판정이 이미 끝난 요청이 실패로 종료됩니다.

next(iterable, None)을 사용하고, 결과가 None이면 저장을 건너뛰십시오.

[from Codex]: The outside-diff StopIteration finding was valid on reviewed head 61bb6df and is already superseded by ffb1383. _psychometric_persistence_lock now spans candidate lookup, observe, records lookup, save, and prune, while pool retention takes the same lock. No concurrent pool mutation or orchestrator observation can remove the row between observe and lookup; the just-observed context is also moved to the LRU tail before bounded eviction. The barrier regression test_runtime_change_cannot_race_a_persisted_psychometric_observation passed five consecutive runs, and the focused set passed 185 tests.
