Supersedes #985 without changing its corrected scientific/product tree.

Scientific slice

Exact source head: 34697b6df58c1424654bc890571a3dfbe806fd97. Repository CI, Security Scan, CodeQL, Semgrep, and ClusterFuzzLite are terminal-success on this SHA, with no unresolved review threads. The Rust-owned MAP/Newton estimator retains crossed and weighted multiple-membership person effects, CPU multithreading, optional wgpu score acceleration with CPU fallback, and a true-parameter RMSE recovery gate that a zero/stub estimator fails.

Python remains validation/marshalling only; no likelihood, gradient, optimizer, recovery arithmetic, or Psychometrics Commons ownership is moved.

Required ordering with #1005

This branch and #1005 have distinct numerical kernels but share nine mutable integration paths, including:

  • crates/fast-mlsirm-py/src/multilevel_bindings.rs;
  • crates/mlsirm-core/src/lib.rs;
  • python/fast_mlsirm/multilevel/__init__.py and estimation.py;
  • ADR-0007, longitudinal doctoring, documentation coverage, and both requirements/research traceability matrices.

#1005 owns the longitudinal state/CT-AR Rasch foundation; this PR owns crossed/weighted multiple-membership u_h estimation. Both must survive. Temporary reconciliation PR #1016 proved GitHub cannot auto-merge those branches without explicit path-level resolution, so this PR is intentionally Draft and must not land independently while #1005 remains open.

After #1005 integrates—or after a reviewed non-force reconciliation preserves both exact scientific slices—regenerate every base-sensitive check and formal review on the resulting head before marking Ready.

Historical review boundary

#985's remaining formal OpenCode CHANGES_REQUESTED is solely central coverage-evidence run 32124700402, created before the current organization .github review/tooling fixes. It is historical infrastructure evidence, not source approval. No force push, review dismissal, gate weakening, or unrelated repository write is used.

Add a Rust-owned MAP/Newton kernel for Fox & Glas mixed-effects IRT
person effects with Browne MMMC crossed and weighted membership. The
O(P*I) score reduction is CPU-multithreaded and optionally GPU-backed.
Python only marshals a sealed design. Recovery is RMSE vs true u_h.

Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
The crossed u_h binding now uses PyValueError::new_err, and the APA 7th
doctoring test accepts the wrapped Browne MMMC title.

@opencode-agent Reconcile this same current branch feat/multiple-membership-current-review-985@34697b6df58c1424654bc890571a3dfbe806fd97 with parent #1005 exact head ed9868c1b3636d0470dc82367e80a43036483018 using a normal two-parent, non-force merge commit. Do not rebase, squash, force-push, or merge either product PR to main.

Resolve the nine shared paths by preserving both scientific slices:

  • crates/fast-mlsirm-py/src/multilevel_bindings.rs: retain longitudinal/CT-AR bindings from feat(longitudinal): replay Rust CT-AR Rasch on current review workflow #1005 and crossed/weighted u_h estimator bindings from this branch.
  • crates/mlsirm-core/src/lib.rs: export both longitudinal modules and multilevel/gpu/estimator modules; do not drop either public surface.
  • python/fast_mlsirm/multilevel/__init__.py and estimation.py: retain both longitudinal state/CT-AR public APIs and crossed multiple-membership estimation APIs with their trust boundaries.
  • docs/adr/0007-multilevel-multiple-membership-temporal.md, docs/doctoring/multilevel_longitudinal_measurement.md, docs/documentation_coverage.md, docs/traceability/requirements-matrix.md, and docs/traceability/research-basis.md: synthesize both accepted scientific claims/references rather than choosing one side.

Preserve all non-shared files from both branches. Do not modify formulas, tolerances, recovery thresholds, locks, workflows, aggregate CHANGELOG.md, or unrelated files. Run cargo fmt/check/tests plus focused Python multilevel/longitudinal tests. Commit to this same branch. If exact head moved, refetch/delta-inspect first and adapt only if compatible.

After the merge, I will retarget #1014 to #1005's branch so #1005 lands first and #1014 shows only its unique crossed-estimator delta.

@opencode-agent @cwl-noema-review Please independently review exact current head 34697b6df58c1424654bc890571a3dfbe806fd97 against live main. Security Scan 32208921039, CodeQL 32208921131, Semgrep 32208921063, ClusterFuzzLite 32208921117, and every required Python/Rust/package/fuzz job in CI 32208921099 are terminal-success; the workflow-level CI conclusion is cancelled only because gpu-smoke was cancelled during Vulkan provisioning, the same repository-owned first causal boundary now isolated in #1021. Inline review threads and formal reviews are empty. Verify the Rust-owned crossed/weighted multiple-membership MAP/Newton estimator, CPU multithreading and optional wgpu score acceleration/fallback, true-parameter RMSE recovery gate, and Python validation/marshalling-only boundary without transferring #985 predecessor evidence.

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 34697b6df58c1424654bc890571a3dfbe806fd97.

Fresh re-review request: ContextualWisdomLab/.github#1136 has merged, fixing the central coverage-evidence bug (_install_trusted_uv() target-triple validation) that caused the prior REQUEST_CHANGES verdict on this PR. Please re-review exact current head 34697b6df58c1424654bc890571a3dfbe806fd97 — the underlying infrastructure blocker is now resolved on .github main. Do not transfer evidence from any prior head.

The draft is ready for review. Re-review exact current head 34697b6df58c1424654bc890571a3dfbe806fd97 against protected main base 04d0bc21a2a20693bcf16108cd76d394fe844d23; use current Checks only. Current named Checks have no non-success terminal conclusion. Local documentation/contract validation passed 4 tests; Rust and Python CI provide the compiled crossed multiple-membership estimator recovery, determinism, and CPU/GPU fallback evidence.

Current-head check review for 34697b6: all named checks are terminal-success except the historical GPU-smoke check, whose run was cancelled during the Install software Vulkan adapter step while all other matrix jobs passed. A failed-job rerun was dispatched for run 32208921099; no source change or GPU gate weakening is justified. Please reacquire review evidence against this exact head. @opencode-agent review @cwl-noema-review review

Current-head re-review request for 34697b6df58c1424654bc890571a3dfbe806fd97 against protected main. The prior REQUEST_CHANGES verdict cited predecessor or superseded coverage evidence; re-fetch the exact current-head coverage-evidence result and review the complete current diff.

Exact-head validation for the Draft crossed/multiple-membership Rust slice 34697b6df58c1424654bc890571a3dfbe806fd97:

  • cargo test -p mlsirm-core --lib multilevel -- --nocapture: 29 passed, including true-effect RMSE recovery, one-hot/cross-classified/weighted membership, worker-count determinism, and malformed-design guards.
  • Python contract/doctoring selection: 5 passed; 2 recovery cases are locally environment-limited because this isolated worktree has no compiled PyO3 _core.

The branch remains intentionally Draft and stacked with the longitudinal #1005 integration paths; no independent merge or duplicate ownership was attempted. Re-fetch exact heads after reconciliation and regenerate protected review/check evidence. @opencode-agent review @cwl-noema-review review

Additional native package proof for exact head 34697b6df58c1424654bc890571a3dfbe806fd97:

  • Built the mixed project wheel from the branch with maturin build --release; imported fast_mlsirm._core successfully.
  • With that exact wheel preloaded, the full crossed/multiple-membership Python regression set passed: 7 passed, including true-effect recovery and Rust/Python contract paths.

The earlier isolated no-extension limitation is resolved for this proof. The PR remains Draft because #1005 and #1014 share mutable bindings/documentation paths and require reviewed reconciliation before any merge. @opencode-agent review @cwl-noema-review review
