현재 exact head 6ab2489113917f6c510fed2c4bb786f8945badfb는 repository CI·CodeQL·Security·Semgrep을 통과했지만, 이 PR이 실제로 바꾸는 scientific execution baseline에 대한 exact-head 증거가 없습니다.
statistical-studies.yml은 Rust 1.98.1로 Kang–Jeon literature true-parameter recovery, higher-order DINA Monte Carlo recovery, GRM 500-rep recovery, GPU↔CPU recovery parity, ignored Rust/PyO3 studies를 모두 실행하도록 변경됩니다. 그런데 이 workflow trigger는 workflow_dispatch, default-branch schedule, v* tag뿐이라 이 PR head에서는 자동 실행되지 않습니다. 일반 CI GREEN만으로는 compiler baseline 변경이 ignored/release-mode scientific kernels의 recovery·parity 결과를 보존한다고 증명할 수 없습니다.
수정은 workflow에 모든 PR trigger를 추가하는 쪽이 아닙니다(대형 Monte Carlo를 모든 PR마다 돌려 60-job ceiling을 악화시키지 마세요). 이 exact head/ref에서 Statistical Studies를 명시적으로 실행해 모든 applicable study jobs를 terminal GREEN으로 확보하고, 특히 literature CPU recovery, GRM 500-rep, GPU parity의 결과를 PR evidence에 연결해 주세요. 실패하면 Rust 1.98.1에서의 실제 numerical/scientific regression을 RED로 고정한 뒤 최소 causal fix가 먼저입니다. 성공하기 전에는 compiler baseline을 merge-ready로 보지 않습니다.
현재 source diff 자체에서는 별도의 기능 결함을 만들지 않았고, public crate MSRV를 올리지 않은 선택과 workflow/toolchain drift contract는 유지해도 됩니다.

Fresh intervening-delta review adopts |
Superseded by current head 248b17c. The source finding was repaired by a pull_request Statistical Studies trigger scoped only to rust-toolchain.toml plus a regression contract; exact-head scientific run 34230054113 is now instantiated but remains pending, so this dismissal is not approval or scientific GREEN.

Current-head repair review on exact e49e631fbd672b27d408854d6c2409eea9ae073d.
The new CodeRabbit findings were valid. On predecessor 5cdc2ece..., all five ordinary CI actions/checkout steps persisted the read-only job token while later steps executed pull-request-controlled Python/Rust/fuzz/package code. A fail-first regression is preserved as commit fa8e3fb10df6057a17fdfc8022d7a2bfacd3fc25; against its parent workflow the count-independent contract necessarily fails because each checkout block lacks with: persist-credentials: false. The child repair adds that control to all five checkout steps and does not change permissions, commands, numerical code, scientific denominators, estimator settings, or acceptance thresholds.
The dedicated scientific evidence-job contract gap is also repaired: correlated-MIRT, all four QMC-MIRT cells, GPCM-MHRM, MHRM, and both testlet cells now independently assert --exact, --test-threads=1, and if-no-files-found: error. Current production statistical-studies.yml already satisfies those controls, so this is regression coverage rather than a workflow semantic change. The CodeRabbit inline thread is resolved only after re-reading the exact-head test source.
Effective delta from 5cdc2ece... is four files: CI +10 lines, changelog +2, new security regression +23, scientific contract +15. The branch advanced once by non-force fast-forward through RED then GREEN, avoiding multiple synchronize pushes. Predecessor Statistical Studies run 34415911818 is therefore correctly cancelled as stale-head evidence; new exact-head CI/security/scientific runs must establish acceptance. No predecessor partial scientific result is transferred to this head.

Current exact authority refresh for The compiler-baseline/scientific lane has now completed its current-head execution rather than remaining queued. Exact-head Landing is still not admissible. Required CodeQL PR Review state is also not landing-complete: the only inline CodeRabbit thread is resolved, current-head OpenCode is COMMENTED rather than APPROVED, and there is no qualifying independent current-head APPROVED review.

Scope
Upgrade the repository-owned Rust compiler baseline from 1.97.1 to 1.98.1 without changing the published crate MSRV contract or LSIRM/MLSIRM/IRT numerical semantics. Compiler identity is synchronized across
rust-toolchain.toml, repository CI, and Statistical Studies. Compiler changes require exact-head recovery/parity evidence rather than ordinary CI alone.Repair and scientific-evidence lineage
The branch preserves the design and acceptance contract while repairing evidence-budget and workflow-contract failures discovered during admission. Literature-grade Monte Carlo jobs were split only where the prior aggregate job budget prevented terminal evidence; repetitions, N, dimensions, deterministic seeds, estimator paths, tolerances, denominators, RMSE/bias/convergence/theta-correlation thresholds, and public APIs were not weakened.

Every QMC cell preserves 500 replications, D=4/D=5, N=2,000/1,500, Halton point counts 4,000/6,000, deterministic response generation and seed, loading/intercept design, canonical
fit_2pl/TwoPlConfigestimator path, and the existing convergence/RMSE/bias/theta-correlation acceptance. No sample reduction, tolerance relaxation, threshold weakening, xfail, source rewriting, or denominator change is used to fit the Actions wall clock.The current security/test-contract repair changes no production likelihood, scoring, convergence implementation, GPU arithmetic, stable public API behavior, or scientific-study semantics.
Landing rule
Normal merge requires one unchanged exact head with every applicable protected and scientific gate terminal GREEN, zero valid unresolved findings, and a qualifying independent current-head approval. Do not use predecessor evidence as current-head success, no-op retriggers, broad reruns, self-approval, bypass, force-push/destructive rebase, or leaf copies of foreign control-plane logic. TEPP temporal/event composition and contextual-orchestrator routing remain foreign-owner concerns.
