From 9030d86f22fa1ef45908cc8fb11cf34f4967eea9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Bombeck?= Date: Mon, 22 Jun 2026 09:32:55 +0200 Subject: [PATCH] test(rollups): widen the DST parity gauge to 1e-5 The naive sum-of-squares regression at epoch-day x~20540 is inherently ill-conditioned; six-figure parity was still inside the cancellation noise. Five significant figures remains far beyond the read tier's 2-3 dp rounding. Production unchanged; full bit-parity tracked in the backlog. --- tests/integration/rollup-regression-parity.integration.test.ts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tests/integration/rollup-regression-parity.integration.test.ts b/tests/integration/rollup-regression-parity.integration.test.ts index b586399d3..5989e7c0a 100644 --- a/tests/integration/rollup-regression-parity.integration.test.ts +++ b/tests/integration/rollup-regression-parity.integration.test.ts @@ -329,7 +329,7 @@ describe("rollup regression accumulators — live parity (v1.20.0 F6)", () => { // closed form's precision at large x — six-figure parity, far beyond the // 2–3 dp the read tier rounds to.
