 CI database preflight connects from the same job container and with the same URL as integration tests. Service health alone does not verify that the job can reach PostgreSQL. Diagnose connection failures separately from application assertions; do not skip the integration suite when preflight fails.
 
+All browser suites launch through `tests/support/browser.cjs`. `MEGURI_BROWSER_CHANNEL=chromium` selects Playwright's bundled browser without a branded channel; unset selects locally installed Chrome. Individual suites must not hardcode launch channels. CI installs Chromium and sets this variable for the whole browser run.
+
 Before enabling a provider in production: publish a preview to its dedicated test team, compare the actual timeline, repeat unchanged, interrupt a partial publication, introduce external drift, verify conflict and explicit overwrite, and exercise escalation/routing on the target subscription. Record evidence and limitations.
 
 See [JSM environment and acceptance preparation](jsm-acceptance.md) for current test-site options and the live verification sequence.
