Detailed Description

Deterministic boot self-check results (the app's golden numbers).

Four framebuffer hashes taken after four scripted viewport states, plus the tile cache's own counters. Because the render is pure integer these are identical on the unit-test host, in ra8_emulator and on silicon – which is what makes them a usable golden.

Invariant

All four hashes differ (each stage changes visible pixels).

Example:

ez_selftest_t st = {};
(void)ez_scene_selftest(&scene, &st);
