Summary

ADR 0012 first production slice: compositional topic coordinates. Rebased onto main after #47.

  • New topic_measurement crate (no migration; 0007 remains owned by feat(persistence): retention deletion legal-hold SQL contracts (0007) #45)
  • additive_log_ratio / from_additive_log_ratio with max-shifted stable maps
  • True-parameter recovery RMSE on known simplex
  • refuse_lexical_inferential_weight rejects TF-IDF / BM25 / keyword as estimator coordinates
  • Workspace contract includes topic_measurement

Serial

Test plan

  • Exact-head Rust CI / coverage / docs quality
  • OpenCode APPROVE when org gates allow (cannot self-approve)
  • Squash-merge when CLEAN

Summary by CodeRabbit

  • 새로운 기능
    • 토픽 비율을 안정적인 ALR 좌표로 변환하고 원래 비율로 복원하는 기능을 추가했습니다.
    • 잘못된 조성, 비유한 값, 차원 오류 및 수치 불안정 입력을 안전하게 거부합니다.
    • TF-IDF, BM25, 키워드 기반 점수를 추론 좌표로 사용하는 것을 제한합니다.
  • 문서
    • logistic-normal 토픽 좌표, ALR·ILR 적용 기준과 검증 결과를 문서화했습니다.
    • 새 토픽 측정 기능의 구현 상태와 추적성 정보를 갱신했습니다.
  • 검증
    • 변환 왕복 정확도, 극단값 처리 및 입력 검증에 대한 테스트를 추가했습니다.

📝 Walkthrough

Walkthrough

topic_measurement Rust 크레이트를 추가했습니다. 크레이트는 안정적인 ALR 순·역변환, fail-closed 조성 검증, 어휘 기반 추론 가중치 거부를 제공합니다. 워크스페이스 계약과 관련 연구·검증 문서도 갱신했습니다.

토픽 측정 기반

Layer / File(s) Summary
크레이트 계약과 공개 API
crates/topic_measurement/Cargo.toml, crates/topic_measurement/src/error.rs, crates/topic_measurement/src/lib.rs
topic_measurement 패키지와 TopicMeasurementError를 추가했습니다. ALR 변환과 어휘 가중치 거부 API를 공개적으로 재수출합니다.
ALR 변환과 수치 검증
crates/topic_measurement/src/coordinates.rs, crates/topic_measurement/tests/*
양의 단체 조성을 검증하고 ALR 좌표로 변환합니다. max-shift 기반 역변환과 언더플로우 검사를 추가했습니다. 왕복 복원, 정밀도, 극단값 및 오류 계약을 검증합니다.
어휘 가중치 거부 계약
crates/topic_measurement/src/lexical.rs, crates/topic_measurement/tests/logratio_recovery_contract.rs
정규화된 tfidf, bm25, keyword 방법을 LexicalWeightForbidden으로 거부합니다. 허용 방법과 거부 방법을 검증합니다.
워크스페이스 연결과 구현 기록
Cargo.toml, scripts/check_workspace_contract.py, tests/quality/test_check_docstrings.py, ARCHITECTURE.md, README.md, CHANGELOG.md, DOCUMENTATION.md, docs/*
새 크레이트를 워크스페이스와 계약 검사에 연결했습니다. 구현 상태, ALR·ILR 적용 규칙, 참고문헌, 추적성 및 검증 문서를 갱신했습니다.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to f3540

The new topic-measurement behavior is localized, but the current branch still needs a true-parameter ALR RMSE assertion and correction of two ADR index maturity labels. These are bounded correctness and documentation issues requiring explicit owner follow-up before merge.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

  • Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

  • Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

  • Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

  • Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

  • Result: REQUEST_CHANGES

  • Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head a3de3fb1179708f18dee414ef4c5ff63e711e77d.

@opencode-agent review exact current head a52dd55. Serial ready PR after #45/#47. ALR remains the logistic-normal map (Aitchison & Shen, 1980; Blei & Lafferty, 2007); sequential Egozcue ILR is the orthonormal Aitchison-distance isometry (Egozcue et al., 2003). Approve only this SHA after same-head coverage-evidence success.

Status on exact head a52dd5597cc53943a9c3c5a339dd9e10fb216524 (do not push unless a new scientific defect exists — empty retrigger commits are forbidden):

  • Rust Foundation CI, live Postgres, line coverage, nightly branch coverage, Semgrep, Strix, Security Scan, docs, and scan-pr-queue are terminal-success.
  • Closed-form ALR (ln 2, ln 3) and sequential Egozcue ILR RMSE assertions are already on this SHA (Aitchison & Shen, 1980; Egozcue et al., 2003).
  • Analyze (python) and noema-review failed on GitHub HTTP 503 while uploading/querying, not on TEPP findings. This token cannot rerun those workflows.
  • OpenCode still has stale CHANGES_REQUESTED on ab29247. Owner mention for this SHA is in-thread; scheduled mention sweeps are being cancelled by org queue saturation.
  • Keep this the only ready TEPP PR. docs(adr): wire verified method papers into temporal and psychometric ADRs #116 stays draft.
