 * Whether the installed Playwright probes an https url tunnelled through a

 * started honoring the caller's setting. The readiness gate and its graph-time
 * inference follow the installed version: verifying where that version's own
 * probe does not would fail a wait Playwright itself would pass, and counting
 * TLS material that probe never reads would drop a gate for nothing.
 * `version` is the installed version as `installedPlaywrightVersion` reads it;
 * an unresolvable or unparseable installation (`null`) reads as verifying, the
 * semantics of current versions.
