• 🔴 (03:07) Test coverage includes the exact case "checks for update when never checked before" and invokes the background update-check path when no prior check exists.
• 🔴 (03:07) Release-fetch tests expect the Toolkit GitHub API URL https://api.github.com/repos/getsentry/toolkit/releases?per_page=30.
• 🔴 (03:07) Added invalid GitHub release-pagination handling with the exact error message "GitHub returned an invalid release pagination URL".
• 🔴 (03:07) versionExists("curl", "1.0.0") is covered for a successful result resolving to true, while a failure path must reject with { reason: "network_error" }.
• 🔴 (03:07) Added source-specific nightly-version coverage for versionExists("curl", "0.14.0-dev.1772661724", UPGRADE_SOURCES[0]); requests must not target URLs containing getsentry/cli.
• 🔴 (03:07) Toolkit OCI authentication mocks return { token: "toolkit-token" } and recognize the exact registry scope scope=repository:getsentry/toolkit:pull.
• 🔴 (03:07) Background update-check tests cover clean cancellation through abortPendingVersionCheck() and invoke maybeCheckForUpdateInBackground().
