Fit: sm.GLM(y/n, X, family=Binomial(), var_weights=n).fit(scale='X2', tol=1e-12, maxiter=200). Dispersion = Pearson X2/df_resid (df_resid 77 for 84 donors, 66 for 73). Wald p = two-sided normal on coef/SE (q uses this); I also give p_t (t on df_resid, as R summary.glm) and its BH q_t. BH (fdr_bh) over the 130 tested supertypes, separately per term and per run. Sensitivity 'excl severe' keeps the same 130 supertypes, 73 donors.\n\nIMPORTANT for checkers (and the task's how_to_check): in statsmodels 0.14.5, sm.GLM(np.column_stack([y, n-y]), X, Binomial()).fit(scale='X2') returns the SAME coefficients but a dispersion on the wrong scale (Sst_3: 0.00296 instead of 33.498) and SEs about 100x too small, which makes ~127/130 interactions 'significant' with p≈0. My first run did exactly this; I caught it and switched to proportion endog + var_weights=n. The code asserts that res.scale equals sum((y-n*mu)^2/(n*mu*(1-mu)))/df_resid to 1e-8. Independently, a plain-numpy IRLS refit (crosscheck_irls.py) of all 130 x 3 runs agrees: max |d coef| 5.2e-10, max |d SE| 5.1e-10, max relative d(dispersion) 4.6e-10. This var_weights form is what R glm(cbind(y, n-y) ~ ..., family=quasibinomial) computes.\n\nRESULTS\nMain (carrier, 84 donors): interaction q < 0.10: none. Smallest: Astro_4 (845 nuclei) b = 7.5519, SE 2.3096, p = 0.0011, q = 0.140; Astro_5 b = 2.910, p = 0.020; Sncg_6 b = 1.573, p = 0.026; Oligo_1 b = -2.462, p = 0.027; Sst_9 b = -1.350, p = 0.045 (q 0.72). 5 of 130 interactions nominal p < 0.05; 67 of 130 negative. Sst_* family: 15 of 16 interactions negative (only Sst_11 positive), 1 of 16 nominal p < 0.05 (Sst_9); none q < 0.10. CPS_Local main effect (slope in non-carriers): 21 supertypes q < 0.10 (min q 0.0089). APOE4 main effect: none q < 0.10 (min p 0.0053, min q 0.68).\nSensitivity excl. 11 severely affected donors (73 donors): interaction q < 0.10: none (Astro_4 b = 8.132, p = 0.00079, q = 0.103). Sst_*: 15/16 negative; nominal p < 0.05: Sst_9 (b -1.532, p 0.027), Sst_19 (b -1.904, p 0.028). CPS_Local q < 0.10: 7; APOE4: 0.\nSensitivity ε4 dose (84 donors): interaction q < 0.10: Astro_4 only (b = 4.7531 per allele, SE 1.3225, p = 3.25e-4, q = 0.042; positive, i.e. Astro_4's share rises more steeply with CPS_Local per ε4 allele; 845 nuclei, 6 ε4/ε4 donors). Sst_*: 13/16 negative; nominal p < 0.05: Sst_9 only (b -1.192, p 0.024). CPS_Local q < 0.10: 10; APOE4: 0.\nReading: the Sst_* interactions lean negative (steeper loss with local pathology in carriers) but, with 25 carriers and Pearson dispersions of 3 to 34 in that family, no single Sst supertype's interaction survives multiple testing; I do not test the sign pattern (supertype shares are compositional and correlated, so 15/16 is not an independent-sign test). This is a measurement on one cohort; it is not advice of any kind.\n\nSPOT-CHECK VALUES (main, carrier): Sst_3 nuclei 7699, dispersion 33.49791944, int b -1.024666531, SE 0.909875095, p 0.2601.

Both inputs matched declared SHA-256 and size: metadata 518e6c045d2a91c694c74d4cba099b86e64829f6053ba42684d2ec3ebf0bd3a6 / 1,153,185,413 bytes; CPS 74cee4af83870a285c7aa3ccc26f8dd1aa9b7213662b21c0c1c2fee312c5a41b / 55,147 bytes. Rebuilt 1,178,694 nuclei, 84 donors, 148 supertypes, 25 APOE4 carriers, 11 severe donors; all 84 MTG donor IDs joined. The sorted donor-by-supertype CSV exactly matched SHA-256 69cdfe3f1dda26506fc3d5e9112a608a1ff9adebc8b5208b6223a2daf27382ba. I fit each of the 130 >=500-nucleus supertypes with statsmodels GLM(y/n, Binomial, var_weights=n), Pearson X2 scale, and BH correction, including both sensitivity runs. All declared outputs reproduced within tolerance: Sst_3 interaction b=-1.024666531055, SE=0.909875094967; Sst_9 b=-1.350251421356, p=0.0447809; Astro_4 main b=7.551850854911, q=0.139952878; excluding severe donors Astro_4 q=0.102755434; dose Astro_4 b=4.753144548256, q=0.042303560. No main-carrier or exclude-severe interaction had q<0.10; dose had Astro_4 only. The Sst family was 15/16 negative with only Sst_9 nominally significant. The claim exactly matches these results and the measured evidence label is correct. Novelty search found the closest primary SEA-AD paper used APOE4 only as an additive covariate (formula sex + age + race + chemistry + APOE4 + CPS), not a CPS-by-APOE4 interaction; other hits addressed transcriptomic genotype effects or multiregional vulnerability, not this abundance interaction.",
