mask-risc + jc: grouped power-sums / cross-power-sums terminals; ANOVA, Pearson, OLS from power sums; perturbation-sim angle_cov - #1323
Conversation
mask-risc: Terminal::GroupMomentsI32 { mask, key: GroupKey, val } folds
(n, Σx, Σx²) per group into a new Out::Moments sink, one delegation per
tile to ndarray::simd::masked_group_moments_i32{,_via,_pair}. It is its
own terminal, not a GroupFold member: a GroupFold slot is one seeded i64.
Validation refuses a wrong-width key/value lane, a missing or wrong-shaped
sink, a plane past the 2^32-row exactness bound, and a partial extent.
The independent oracle folds straight to i128; the key resolution it
shares with GroupReduce is now one longhand helper (row_group), and the
data type reaches it through value.rs so the oracle still never names the
SIMD facade (law L4, guarded by the_oracle_has_no_facade_token).
jc: anova_from_moments / eta_squared_from_moments project the same
statistics as anova_one_way / eta_squared from grouped moments. The F / p
/ η² policy and every None case now live once, in anova_from_ss and
eta_from_ss, shared by both paths. Sums of squares are formed from exact
i128 quantities (W_g = n·Σx² − (Σx)², D_g = N·S_g − n_g·S), so no two
large floats are subtracted and zero within-group variance is detected
exactly.
Tests: executor == oracle for GroupMomentsI32 on resident, VIA and pair
keys across tiles; refusal cases; and in jc, mask -> fold -> moments ANOVA
vs materialized -> anova_one_way over arbitrary masks, unequal groups,
negative values, values near the i32 bound, chunk-merge identity,
degenerate layouts, and an adversarial layout where the two-pass slice
path loses the within-group variance.

… R² from moments
mask-risc: Terminal::GroupCrossMomentsI32 { mask, key: GroupKey, x, y }
folds (n, Σx, Σy, Σx², Σy², Σxy) per group into Out::CrossMoments, one
delegation per tile to ndarray::simd::masked_group_cross_moments_i32{,_via,
_pair}. Same key addresses, drops, 2^32-row bound and extent refusal as
GroupMomentsI32; the independent oracle accumulates all six fields in
i128 row by row and names the type only through value.rs (law L4).
jc: pearson_from_cross_moments, sample_covariance_from_cross_moments,
simple_regression_from_cross_moments (SimpleRegression { slope, intercept })
and r_squared_from_cross_moments. The centred sums n·Σxy − Σx·Σy etc. are
formed exactly in i128 (checked; None past the bound). Each projection
shares its acceptance policy with the slice implementation it mirrors,
extracted as pearson_from_centered (reliability), sample_cov_tail and
r_squared_tail (stats) — no second definition of Pearson, the covariance
convention (n−1) or the R² slack rule. R² follows multiple_r_squared's
one-predictor contract (n ≥ 3, constant x or y → None).
Recorded finding: unlike one-way ANOVA, the slice pearson /
multiple_r_squared are two-pass and do NOT fail under a huge offset with a
tiny spread; a naive f64 projection of the same moments does (NaN), which
is what the exact i128 centring prevents. The regression test asserts
both halves against an independently computed exact reference.

The first fixture (i128::MAX/2 sums) wrapped to negative centred squares, so it was refused by the >= 0 check and passed with every checked operation replaced by wrapping arithmetic. The new fixture wraps to a plausible positive value (n·Σx² = 2^128 + 2^33 -> 2^33), so a wrapping implementation would report a confident r = 1; verified by a disable run.

…a CovHighD::sandwich Sigma_theta = L+ Sigma_p L+ is the stochastic twin of pseudo_apply and is exact (not first-order) for DC flow in a fixed topology. L+ is symmetric, so it is ndarray's Pillar-9 sandwich M·Σ·M with M = L+; no local kernel. New default-off feature 'pillar' (dep:ndarray + ndarray/pillar). Stated limits: f32 inside the sandwich (measured ~1e-7 rel vs an f64 triple product), const-generic N checked against the runtime bus count, and an asymmetric Sigma_p is refused rather than silently lower-triangled. Out of scope, documented: line trips (a rank-1 update of L+, not a sandwich) and line-flow covariance (non-symmetric rectangular Jacobian). Tests: rank-1 case against pseudo_apply's outer product (never forms L+), f64 dense triple product, 40k-sample Monte Carlo of the deterministic solver (rel err 0.0009), N-mismatch and asymmetry refusals.

…e duplicate record)
ndarray master shipped PowerSums { n: u64, sum: i64, sum_sq: u128 } — the
same record this branch had introduced as GroupMoments. The ndarray side
of this branch was rebuilt on master to add only checked_merge and the
joint fold (CrossPowerSums), so consumers move to the upstream names:
- GroupMoments -> PowerSums, GroupCrossMoments -> CrossPowerSums
- masked_group_(cross_)moments_i32* -> masked_group_(cross_)power_sums_i32*
- sum_x2/sum_y2 -> sum_x_sq/sum_y_sq; x_moments()/y_moments() -> x()/y()
- EMPTY -> default()
Square sums are u128 upstream. jc's exact i128 centring converts them
with i128::try_from; one past i128::MAX is already outside the documented
2^32-row bound and returns None, the existing policy. mask-risc's own IR
names (Terminal::GroupMomentsI32, Value::GroupMoments) are unchanged.

GroupPowerSumsI32 and GroupCrossPowerSumsI32 were refused by execute_extent although their per-extent results merge exactly by PowerSums::checked_merge / CrossPowerSums::checked_merge. Admit them: each call seeds its own sink, and the edge word's mask is clipped to the extent like the other mergeable folds. tests/extent.rs pins the law: whole-population execution equals the group-by-group checked_merge of any partition, in any order, for the resident, VIA and pair key forms, at two tile widths. The two refusal assertions in tests/foreign.rs are removed with this change.

When a valid finite covariance or pseudo-inverse entry exceeds f32::MAX, these casts silently produce infinity, so CovHighD::sandwich can return NaN/infinite entries even when the true f64 product is finite (for example, a large Σp combined with a correspondingly small L⁺). This also contradicts the documented roughly 1e-6 relative-error expectation; either rescale before narrowing or explicitly reject values outside the supported f32 range.
Useful? React with 👍 / 👎.
There was a problem hiding this comment.
Fixed in 898179f. Each input is divided by its largest absolute entry before the f32 narrowing, and the result is multiplied back in f64. The sandwich is bilinear, so this is exact up to rounding. Non-finite sigma_p entries now panic. The new test magnitude_outside_f32_range_is_exact_up_to_rounding covers magnitudes 1e45 and 1e-45 against the f64 triple product, and it fails when the rescaling is removed. The module doc now states error relative to the largest output entry.

Two review findings on the f32 sandwich: - A huge sigma_p entry (e.g. in L+'s null space) set the global scale, so the entries that determine the output flushed to zero in f32 and the result was silently wrong. A nonzero entry that would fall below f32::MIN_POSITIVE relative to the max is now refused. The module doc now states the error bound relative to the input magnitude, not the output. - The combined factor scale * l_scale^2 could overflow to infinity and turn an exact-zero entry into NaN.
