Why

GAP-003A / issue #166 still has no operator-visible cancel path. docs/API_CONTRACT.md documents POST /v1/analysis-runs/{run_id}/cancel and accepted/running → cancelled, but protected main refuses every non-create analysis-run path.

Live slices that this PR does not duplicate:

What

Fifth GAP-003A slice on protected main 1bc02f580cf48e1d39da239f0e818453437c31c3:

  • POST /v1/analysis-runs/{run_id}/cancel on AnalysisRunLiveService
  • accepted and running → metric-free cancelled (200)
  • already-cancelled is idempotent
  • succeeded, failed, and unknown runs fail closed
  • cancel bodies and cancelled status refuse RMSE/bias/coverage/SE-gate/scientific_acceptance/report keys
  • GET /v1/analysis-runs stays 400 on this head
  • ADR 0029 (0026–0028 live on other GAP-003A PRs)

Not an ADR 0014 scientific claim. Not persistence. Not GET status. Not lifecycle POST.

Verification

  • cargo clippy -p tepp_api --all-targets -- -D warnings
  • cargo test -p tepp_api --all-targets
  • RUSTDOCFLAGS='-D warnings' cargo doc -p tepp_api --no-deps
  • python3 scripts/validate_documentation.py
  • python3 scripts/check_docstrings.py

Exact-head Checks on dba3db0e0a43acae929263a06ff3364802f565f3 are required before merge. Two independent current-head APPROVEs are required. Author cannot self-approve.


Devin Review

Summary by CodeRabbit

  • 새 기능

    • 수락되었거나 실행 중인 분석 실행을 취소할 수 있는 HTTP 엔드포인트를 추가했습니다.
    • 취소된 실행은 측정 결과 없이 cancelled 상태로 표시됩니다.
    • 취소 요청의 형식과 멱등성 키를 검증하며, 과학적 지표가 포함된 본문은 거부합니다.
  • 문서

    • 분석 실행 취소 API의 사용법, 상태 전환 및 제한 사항을 문서화했습니다.
  • 버그 수정

    • 완료되었거나 실패했거나 존재하지 않는 실행의 취소를 안전하게 거부합니다.

GAP-003A fifth slice: POST /v1/analysis-runs/{run_id}/cancel returns
metric-free cancelled status. Succeeded, failed, and unknown runs fail
closed. Does not duplicate GET status (#359) or lifecycle POST (#360).

🟡 Cancellation breaks version-one consumers

When cancellation returns cancelled, existing v1 consumers reject AnalysisRunStatusState. Their version-one contract recognizes only the previous four states.

Prompt for agents
Version the analysis-run status contract change instead of adding cancelled to the existing v1 wire vocabulary. Preserve a v1 representation/parser for accepted, running, succeeded, and failed, introduce a new status contract version that includes cancelled, and update the cancel endpoint, headers/version negotiation, tests, schemas, documentation, and migration guidance so strict existing v1 consumers remain interoperable.

📝 Walkthrough

Walkthrough

tepp_api에 루프백 전용 분석 실행 취소 HTTP 엔드포인트를 추가했습니다. accepted 및 running 실행은 메트릭 없는 cancelled 상태로 전환합니다. succeeded, failed, unknown 실행과 메트릭 페이로드는 거부합니다. 관련 상태 계약, 테스트, 스키마와 문서를 갱신했습니다.

crates/tepp_api/src/analysis_run.rs, crates/tepp_api/tests/analysis_result_contract.rs, schemas/analysis_run_cancel_request_v1.json
Cancelled 상태와 AnalysisRunStatus::cancelled 생성자를 추가했습니다. 취소 상태는 terminal_result를 포함하지 않습니다. 요청 스키마는 버전, 실행 ID, 멱등성 키를 요구하고 추가 필드를 거부합니다.
취소 HTTP 계약과 교환 생성

라이브 서비스 취소 처리
crates/tepp_api/src/analysis_run_live.rs
취소 경로를 라우팅하고 run_id 인덱스를 관리합니다. accepted 및 running 실행을 취소하고, 이미 취소된 실행을 재생하며, succeeded·failed·unknown 실행을 거부합니다.

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

Merge Risk: 🟡 Moderate · up to dba3d

The new loopback cancellation endpoint can mark accepted or running analysis runs as cancelled, but its authorization boundary relies on loopback access and possession of request values, while the implementation does not establish that running work stops or that cancellation survives restart. These bounded security and lifecycle issues should be explicitly resolved or accepted before merge.

## Context

`docs/API_CONTRACT.md` documents `POST /v1/analysis-runs/{run_id}/cancel` and the lifecycle `accepted/running -> cancelling -> cancelled`. Protected main accepts analysis runs on loopback but refuses every non-create analysis-run path. Operators therefore cannot withdraw an accepted or running run. Returning RMSE, bias, coverage, SE-gate, or `tepp.scientific_acceptance.v1` on a cancel body would treat cancellation as measurement evidence. Stacking this slice onto the live GET-status or lifecycle-POST PRs would duplicate those heads.

취소 수명주기 표기를 직접 전이로 수정하세요.

Line 10은 accepted/running -> cancelling -> cancelled를 문서화합니다. 그러나 Lines 16 및 21은 취소가 원자적 전이이고 Cancelling이 HTTP 상태가 아니라고 정의합니다. 구현된 상태 계약에도 Cancelling이 없습니다. 수명주기를 accepted/running -> cancelled로 변경하세요. 그렇지 않으면 소비자가 존재하지 않는 상태를 처리하거나 대기할 수 있습니다.

Closing as research_lineage_only / superseded by the authenticated destructive-operation contract in #174. Current source proves cancel authorization is consumer + run ID + idempotency key on a loopback listener, not an authenticated principal/resource/purpose grant; the idempotency key is replay identity, not a credential. Review also found a v1 wire-version break. Preserve this branch's lifecycle/idempotency/metric-refusal tests and versioning finding for the future authenticated Analysis Run operations landing vehicle. Descendants based on this branch must be reconstructed without silently reintroducing this mutation endpoint.
