Applied as-is. BUILD_INPUTS now covers server/sim, shared and data as well as the page, so a restart after a simulation-only or data-only change is visible to an already-open page. The tag is still computed once per process. A page still waits until the match, including settlement, is over before it reloads, and a failed check still does not reload.
Tests: node --test test/build.test.js test/ui/build-runtime.browser.test.js — 8 pass, 1 skipped (the Chrome restart test; SP_E2E unset), 0 fail.
