Verdict: CHANGES_REQUESTED at f1e4804.
-
python/fast_mlsirm/two_tier_grm.py:27-32 and crates/mlsirm-core/src/two_tier_grm.rs:145-153 — The identification warning is limited to correlated primaries. With
primary_correlation="identity", any two primary columns with the same free-loading support admit a continuous orthogonal rotation: Phi remains I and the likelihood is unchanged. The validator only requires two items per column, and per-column reflection canonicalization removes signs but not this rotation. Document/enforce an identifying loading pattern for identity mode, and cover a shared-support design so it cannot silently report identified parameters or SEs. -
tests/test_two_tier_grm.py:88-111 and :117-126 — The only new P=2 identity fit and Oakes assertion uses seven quadrature nodes per dimension. Maintainer steering requires study-setting tests/benchmarks to use at least 121 nodes per dimension and then larger counts until estimates stabilize. The present comparison and positive-definite SE claim can pass on an underintegrated likelihood; increase quadrature and show stability at a larger count.
-
tests/test_two_tier_grm.py:91-105 — The
estimateassertion checks only metadata, parameter-count difference and loose log-likelihood proximity. It does not establish the required bit-identical default/explicit-estimate regression against origin/main. Add a deterministic exact-output comparison for the old path (including Phi, trace, estimates and SE labels/dimensions).
The fixed-Phi plumbing appears coherent: initial z is zero, the Phi M-step is skipped, Oakes omits Phi slots, and parameter count drops by P(P-1)/2. Cai (2010, pp. 583-584) and Oakes (1999, eq. 6, p. 480) locators match the local full texts. The Semgrep locations in dif.py and tools/inventory_public_api.py are outside this diff.

Verdict: CHANGES_REQUESTED at exact head 5d13de7.
The three prior findings are addressed in this head. Python and Rust reject identical free-loading support in identity mode while leaving estimate mode unchanged; distinct and nested supports remain admissible, and the documentation correctly calls this a necessary condition. The fixed-Phi sign canonicalization still leaves Phi bit-exact identity. The 121/241-node identity fit plus Oakes SE comparison passed on s1 (1 passed, 149.44 s, 5e-3 tolerances), and the ignored test is routed by statistical-studies.yml's scheduled/manual/tagged rust-ignored shards without a skip entry. The new origin/main golden checks Phi, log-likelihood trace, estimates, and Oakes labels/dimensions at 1e-12; its two focused Python tests passed on s1.
Remaining requested fix: tests/unit/two_tier_grm_tests.rs:431-469 adds the nested-support identity acceptance test using ..valid_config(), whose max_iter is 5 (line 248). This violates the required EM max_iter >= 500 for new tests and the test only checks Ok, so a max-iteration, nonconverged result also passes. Set this test's budget to at least 500 and assert convergence, or keep it explicitly a validation-only test and add a converged identity acceptance test with the required budget. The existing test passed on s1, but that result cannot establish the claimed fit acceptance under the requested EM setting.
Touched Rust files pass targeted rustfmt --check with stable rustfmt; git diff --check is clean. No files were changed.

Verdict: APPROVE at exact head 65fa7b3. The sole remaining finding from review 5274149453 is resolved: the nested-support identity test now sets max_iter=500, requires convergence, rejects max_iter_reached, and checks bit-exact identity Phi. The diff from 5d13de7 changes only this test. On s1, cargo test --release -p mlsirm-core --lib identity_rejects_identical_primary_support_but_accepts_nested_support passed (1 passed, 0 failed, 1234 filtered out); the isolated target was cleaned. GitHub rejected an APPROVE event with HTTP 422 because this is my own PR, so this COMMENTED review records the explicit verdict.
Bind deprecated DIF docstring aliases by function object, and import inventory submodules only after they resolve to a public source file inside python/fast_mlsirm.
This reverts commit 40b1cad. Coordinator decision: the inherited Semgrep Medium findings in python/fast_mlsirm/dif.py and tools/inventory_public_api.py are remediated once, in #2102 (head b653df7). Carrying a second independent fix here conflicts with that PR and is out of this PR's scope. The two-tier identity feature commits are kept.

…n tolerance The origin/main golden compared stored floats with rtol=0, atol=1e-12. That fixture stops on `delta_loglik <= 1e-2 * (1 + |loglik|)` (slack ~3.8e-1 at loglik = -37.15), so it pins a point on the EM trajectory, not a converged optimum: its low-order bits are build-specific. The literal-producing build (linux-x86_64) reproduces them exactly; a macos-arm64 build was reported to differ at the 1e-9 scale. Split the contract instead of loosening it wholesale: - exact, platform-independent: n_iter, termination_reason, trace shape, unit Phi diagonal, Phi symmetry, Oakes SE labels and information shape; - exact within one build: the default path and primary_correlation="estimate" must be bit-identical (assert_array_equal, no tolerance); - stored literals: GOLDEN_CROSS_BUILD_ATOL = 1e-6, documented against both the observed cross-build spread (~1e-9) and the effect size a real change to the estimate path would produce (>= 1e-2). Expected values are unchanged and nothing is skipped. Verified on s1 (linux-x86_64, pre-AVX): tests/test_two_tier_grm.py 15 passed.

APPROVE — independent (non-author) review bound to head 1475b637bf6236625bdaab9693690282d9f0b167. Verdict stated explicitly because a self-review event cannot be submitted via the API (HTTP 422).
1. Prohibitions — all clear
| Prohibition | Finding |
|---|---|
| Swapping expected values | None. Every golden literal (golden_phi, golden_trace, golden_primary, golden_specific, golden_threshold, golden_labels) is byte-identical to the pre-PR file (git diff 1475b637~1 1475b637 touches no literal). |
| Widening a tolerance without justification | atol 1e-12 → 1e-6 is argued in code and verified empirically below. |
| Skipping / xfailing | No skip, xfail, or pytest.mark added; the diff is additive (+54/−1) and the one removed line is the assert_allclose call being reparameterized. |
| Cherry-picking a platform | No sys.platform / machine() branch anywhere in the file. |
| Hiding a failure | The opposite: the loosened comparison is fenced by six new assertions, and the failure mode is documented in the docstring. |
2. Does 1e-6 follow from the stated reasoning?
Stopping rule — verified. crates/mlsirm-core/src/two_tier_grm.rs:1370 is
if final_loglik_change <= cfg.tol * (1.0 + prev.abs()). With tol=1e-2 and prev = -37.22539643782572 (the 6th trace entry) the slack is 3.82e-1; the accepted step was |-37.1508 − (-37.2254)| = 7.46e-2. So the golden really does pin a mid-trajectory iterate, not a converged optimum — the premise of the whole argument holds.
Nitpick: the docstring cites the slack "around loglik = -37.15"; the rule uses the previous iterate -37.2254. Both round to 3.8e-1, so the number is right and the attribution is one iterate off.
Effect size — partially overclaimed (non-blocking). I probed two plausible one-line regressions in the two-tier TwoTierGrmConfig block of crates/fast-mlsirm-py/src/lib.rs on s1 (my own copy; reverted and rebuilt bit-exact afterwards):
| Mutation | phi |
trace |
a_primary |
a_specific |
threshold |
worst |
|---|---|---|---|---|---|---|
newton_iter: 10 → 9 |
0 | 2.63e-07 | 5.22e-05 | 2.09e-02 | 6.34e-05 | 2.09e-02 |
ridge: 1e-8 → 1e-7 |
1.26e-09 | 8.76e-09 | 7.43e-06 | 3.98e-04 | 2.99e-05 | 3.98e-04 |
| identity wired into the default path | 1.05e-01 | 3.11e-02 | 7.65e-02 | 1.62e-02 | 1.46e-02 | 1.05e-01 |
All three are caught at atol=1e-6. But the claim "any behavioural change to the estimate path moves these values by >= 1e-2" is empirically false for the ridge perturbation (worst 3.98e-4) and, per array, for phi/trace/a_primary/threshold under newton_iter as well. This strengthens the choice of 1e-6 rather than undermining it — a tolerance set at the claimed 1e-2 effect size would have missed the ridge regression entirely, and 1e-6 still leaves ~400× margin over it. Please narrow the wording to something the fixture supports, e.g. "the regressions this golden was written for move a_specific by 1e-2 or more; the smallest perturbation I could construct (ridge 1e-8→1e-7) still moves it by 4e-4, ~400× the tolerance."
Note also that the observed cross-build spread (~1e-9) is the same order as the phi delta under the ridge mutation (1.26e-09), so the 1e-9 ↔ 1e-2 framing of the headroom is looser than the docstring implies; the actual operative margin is 1e-9 (noise) ↔ 4e-4 (smallest real regression I found), with 1e-6 comfortably between. Still sound.
3. Do the added exact assertions constrain what the loosened ones no longer do?
Genuinely constraining:
fit.n_iter == 6,termination_reason == "tolerance_met",loglik_trace.shape == golden_trace.shape— integer/string, no cross-platform slack. Caveat: the accepted step (7.46e-2) is 5× inside the slack (3.82e-1), son_iteris robust to small drifts — it stayed 6 under all three mutations above. These pin the trajectory shape, not its values.assert_array_equal(default, explicit "estimate")— the strongest addition. It proves the default keyword is still wired to"estimate"(python/fast_mlsirm/two_tier_grm.py:197) and that theidentitywork merged on this branch did not perturb the estimate path, with zero tolerance. Confirmed to fire: rewiring the core call to"identity"fails the test.
Tautological — flagging for the record, not as a defect:
assert_array_equal(np.diag(fit.phi), np.ones(2))andassert_array_equal(fit.phi, fit.phi.T)are constructively true ofphi_from_z(two_tier_grm.rs:668-683writes literal1.0on the diagonal and mirrorstanh(z)off-diagonal). They cannot fail for any estimate-path regression, so they add no coverage beyond documenting the invariant. Harmless; keep or drop.
4. Other accuracy checks
- "Built on linux-x86_64, reproduces exactly there" — verified independently. I ran the pre-PR test file (
atol=1e-12) against a fresh s1 build of this head: 8 passed. The literals are exact on this platform. - The reported macos-arm64 delta (1.42e-9) remains unsourced — no preserved assertion text exists, and the docstring correctly says so. My review does not rely on it; the 1e-6 choice is justified by the effect-size floor I measured, independently of the unsourced spread.
- Commit message inaccuracy: "tests/test_two_tier_grm.py 15 passed". The file has 8 test functions at this head (10 across both
*two_tier*files); the actual run is8 passed. Please correct before merge — the evidence line should match what the tree produces.
5. Reproduction (s1, linux-x86_64, my own isolated tree)

Verdict
APPROVE. No prohibition is violated, the expected values are untouched, the loosened comparison is fenced by assertions that demonstrably fire, and 1e-6 is empirically well-placed. The two follow-ups are docstring/commit-message precision, not correctness: (a) narrow the ">= 1e-2" effect-size claim to what the fixture supports (smallest real regression measured: 4e-4), (b) fix "15 passed" to "8 passed".
… range Independent review of 1475b63 showed the ">= 1e-2" statement was overclaimed: injected regressions on this fixture move the pinned values by 1.05e-1 (identity rewiring), 2.09e-2 (one fewer Newton step) and 3.98e-4 (10x ridge). The smallest is 3.98e-4, so a 1e-2 tolerance would have missed it - which is the argument for the 1e-6 bound actually used. Docstring and constant comment now state the measured range instead. Documentation only; no assertion, tolerance or expected value changes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XaywGmrm4x6bgbkA4gSvxZ

APPROVE (posted as COMMENTED: the author cannot self-approve, so event=APPROVE returns HTTP 422).
Follow-up independent review of 6b699f69c0b2bc1caae4a43b96fcfe2106ed8169, limited to git diff 1475b637 6b699f69 — the parent was already reviewed.
(a) Scope. Documentation only: 8 insertions / 4 deletions, all inside tests/test_two_tier_grm.py — the comment block above GOLDEN_CROSS_BUILD_ATOL and the test_estimate_path_matches_origin_main_golden docstring. No executable line, no literal, no tolerance value changed. GOLDEN_CROSS_BUILD_ATOL = 1e-6, GOLDEN_N_ITER = 6 and every golden array are byte-identical to the parent.
(b) Claim accuracy. The three numbers and their labels match the injected-regression measurements from the earlier review, in order:
| injected regression | observed max deviation |
|---|---|
| identity rewiring | 1.05e-1 |
| one fewer Newton step (10 → 9) | 2.09e-2 |
| 10x larger ridge (1e-8 → 1e-7) | 3.98e-4 |
The previous wording — "any behavioural change to the estimate path moves these values by >= 1e-2" — was falsified by the ridge case (3.98e-4 < 1e-2). The new text states the measured range instead of the unsupported lower bound, which is the correct fix.
(c) Tolerance argument. Now internally consistent: cross-build spread ~1e-9 < GOLDEN_CROSS_BUILD_ATOL = 1e-6 < smallest injected regression 3.98e-4. The added sentence ("a 1e-2 tolerance would have missed it, which is why the bound below sits at 1e-6") states exactly the separation the measurements support, with no claim of a guaranteed floor on arbitrary regressions.
Note, not a finding. The PR's live head is now d408d30e, a merge of main into the branch (it brings in #2102 and CI/Semgrep work). tests/test_two_tier_grm.py is unchanged between 6b699f69 and d408d30e, so this review's conclusions carry to the live head.
No re-run of the s1 suite or the mutation experiments was needed for a documentation-only delta.

APPROVE (follow-up) — re-review bound to d408d30e2eecc046462df5bc3416ce44cac8448f, confirming the fix for the one substantive finding in my review of 1475b637.
6b699f69 replaces the overclaimed ">= 1e-2" statement with the measured range 3.98e-4 … 1.05e-1 and states explicitly that a 1e-2 tolerance would have missed the smallest case — which is exactly the argument for the 1e-6 bound. The numbers match what I measured on s1 (identity rewiring 1.05e-1, newton_iter 10→9 2.09e-2, ridge 1e-8→1e-7 3.98e-4). Documentation only: the diff on tests/test_two_tier_grm.py between the two heads touches nothing but comment and docstring lines — no assertion, tolerance, or expected value moved.
Re-verified on s1 with my existing build (git diff 1475b637 d408d30e -- crates pyproject.toml Cargo.toml Cargo.lock is empty, so the compiled core is unchanged and the golden cannot have shifted):
# /data/orca/workspaces/fmls-revtol-2114, same venv and CARGO_TARGET_DIR as before
git show d408d30e:tests/test_two_tier_grm.py > tests/test_two_tier_grm.py
nice -n 5 taskset -c 0-9 ./.venv/bin/python -m pytest tests/test_two_tier_grm.py -q # 8 passed in 29.85sTwo leftovers from my earlier review, neither blocking:
- The constant's comment still reads "slack ~3.8e-1 at
loglik = -37.15". The rule attwo_tier_grm.rs:1370uses the previous iterate (-37.2254, slack 3.82e-1). The value is right, the attribution is one iterate off — fix it if you touch the block again. - The
1475b637commit message's "tests/test_two_tier_grm.py 15 passed" is still wrong (the file has 8 tests; the run is8 passed). Immutable in history now — worth a correct count in the squash/merge message.
No new findings. Verdict unchanged: APPROVE.
…entification field #2114 makes primary_identification a required TwoTierGrmFit field; #2077's _stub_fit builds that dataclass and predates the field. Each PR passes alone, so only the integrated tree fails - TypeError on the two from_fit gate tests. Resolve it at the integration point rather than in either PR: _stub_fit now takes an optional primary_identification and, when unset, derives it from the stub's Phi (exact identity -> "identity", otherwise "correlated"), which is what a real fit would carry. The from_fit gate keys off its own orthogonal_primary_identification argument, so no gate behaviour changes. s1 on the integrated tree: tests/test_two_tier_expected_raw.py and tests/test_two_tier_grm.py, 34 passed.

Gateway wheel publication preparation and native CodeQL admissionOwner #1229 merged at Local release publication/notes/supply-chain/gate/idempotency contracts: 154 passed in 117.84s, with the known missing pytest-asyncio configuration warning in the minimal test environment. Actionlint and diff check passed. Latest main subsequently added only gateway recovery code/tests; release implementation and contract files were unchanged. Two clean git-archive builds at the final candidate head and fixed SOURCE_DATE_EPOCH were byte-identical; an isolated no-dependency install verified one contextual-orchestrator 0.2.0 distribution and the expected package file. Wheel Native fast-mlsirm #2112 coordinator job 108606566246 completed SUCCESS on cwlab-s1-01.

Integrated central PR #2429 as 24bdfe0b4fcd093cac4047433211d2cd59d53b43. Deployment audit corrected the initial all-consumer proposal before merge. The final selector admits only .github, contextual-orchestrator, and fast-mlsirm, and additionally requires the exact central noema-review.yml@refs/heads/main workflow identity. Other consumers and PR-authored workflow refs retain hosted execution. Group 3 remains repository-selected and workflow-restricted; repository ID 1283452575 (fast-mlsirm) was added, preserving the existing two repositories and workflow allowlist. Group 6's existing exact-main workflow restriction remains intact. Final head df90cd25e007293a00afd57afd443f274144e205: 90 affected tests passed with GITHUB_ACTIONS=true; actionlint and git diff --check passed. No independent approval was present; this was an explicitly authorized administrative bypass while hosted checks were queued, not an all-green protected merge. Consumer PR #2220 head 62883bd still has queued CodeQL detector job 108612680911, Noema admission job 108612677985, and OpenCode bootstrap job 108612677743. Existing queued jobs retain their original workflow version; no new duplicate run was dispatched. Routing integration does not prove runtime gate success. The five-check validation goal remains open. |
Original five-failure audit (fresh authoritative job records)Original PR head:
The newer CodeQL producer run 36315242280 proved Actions analysis success, but Python found two URL-validation test warnings and terminal settlement failed. #2218 repaired those warnings; the producer result does not substitute for current consumer required-wrapper success.

Applied central #2436 at merge commit 3b36b89ef7c820f715e2d28c08d25fe697fc1f23; verified PR state MERGED at 2026-09-27T12:35:35Z. Exact merged candidate head was 5db8ff988793970ae28d4e8f637a2ea2ead95a56, including fresh main #2434. Root cause of Strix admission not using added runners: current consumer admission job 108617323217 selected ubuntu-24.04. Four metadata-only jobs now select the existing control group only for exact trusted central main workflow identity and central/fast-mlsirm callers. Actual scan image and review/security rules remain unchanged. Group 6 adds only the central strix.yml@refs/heads/main grant and preserves every existing grant and restriction. Verification: baseline routing regression failed; 21 affected tests passed again after main integration; actionlint and git diff --check passed. Maintainer-authorized admin bypass was used while hosted checks were queued; no independent approval was present. This is not a protected green merge or a completed consumer review. Central #2432 independently audited: 13 Noema continuation contract tests pass on 7bc3e689493fd737fc619991b7349d6759a77f40. It repairs the central dispatch destination and rejects stale/fork target identity, but actual model verdict and dispatch completion remain unproven. Strix fixture repair #2430 remains draft pending frozen full shell-harness session 19584. Do not merge it based on targeted tests alone. Current consumer #2220 is still head 4eaeb79; its old queued jobs retain older source revisions. |

fit_two_tier_grm(primary_correlation="identity")fixes Phi to the bit-exact identity matrix from initialization through EM and reflection canonicalization, skips the Phi M-step, and removesP(P-1)/2free parameters. The documented default is"estimate"to preserve existing callers and their correlated-primary fits.TwoTierGrmFitreportprimary_identificationas"orthogonal"or"correlated". PyO3 carries the same result metadata.two_tier_oakes_se(primary_correlation="identity")requires Phi = I and excludes fixed Phi coordinates from its labels, information matrix, covariance matrix, and SE vector. Item likelihood and gradient formulas remain unchanged; the E-step uses the existing normal density path evaluated at Phi = I. There is no separate NumPy objective/gradient implementation to update.from_fitcan later read the new metadata instead of a caller flag; this PR does not change feat(two-tier): expected raw total score E[T|theta_focal] at a fixed primary #2077.Paper basis
