From a75f12219a549ac3b58fe473c8e5b80f0fdb3edf Mon Sep 17 00:00:00 2001 From: Danny Avila Date: Sun, 19 Apr 2026 12:05:51 -0400 Subject: [PATCH] =?UTF-8?q?=F0=9F=A7=AA=20test:=20add=20`\$bitsAllSet`=20v?= =?UTF-8?q?s=20`\$in`=20parity=20+=20perf=20spec?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces `aclEntry.parity.spec.ts` — a side-by-side spec that runs the legacy `\$bitsAllSet` query and the current `\$in`-based query against the same `mongodb-memory-server` fixture and asserts identical output sets for every affected method (`hasPermission`, `findAccessibleResources`, `findPublicResourceIds`, `getSoleOwnedResourceIds`) across all 7 meaningful permBits combinations. Also logs median wall-clock time for the two query paths over 20 runs on an 800-entry fixture, with a loose 3x guard against catastrophic regressions. Initial local numbers: 1.05 ms vs 1.07 ms (findAccessibleResources), 1.10 ms vs 1.05 ms (findPublicResourceIds).
