"""Tests for _web_ui_build_needed — staleness check for the web UI dist.
|
|
|
|
Critical invariant: the dashboard Vite build outputs to hermes_cli/web_dist/
|
|
(vite.config.ts: outDir: "../../hermes_cli/web_dist"), NOT apps/dashboard/dist/.
|
|
The sentinel must be checked in the correct output directory or the
|
|
freshness check is a no-op and the OOM rebuild always runs.
