From db929f4a08ea723af82adfb1bf71e360c66d6455 Mon Sep 17 00:00:00 2001 From: Ettore Di Giacinto Date: Tue, 13 Oct 2026 08:10:18 +0000 Subject: [PATCH] test(config): assert every usecase flag is a distinct bit FLAG_MOTION and FLAG_UPSCALE were both declared as 1 << 26 on separate branches, and a merge combined the two const blocks without a conflict. Add a spec that checks every flag from GetAllModelConfigUsecases() is a single bit that no other flag uses, so a collision fails the tests. FLAG_MOTION itself moves to 1 << 27.
