🔴 (03:05) User-provided upgrade logic always checks for Homebrew first because stored install information may be stale.
🔴 (03:05) User-provided upgrade source includes legacy detection for existing installations without stored install information and auto-saves the detected installation method on a best-effort basis for future runs.
🔴 (03:05) User-provided package-manager detection defaults all other node_modules layouts, including npm and yarn layouts, to "npm".
🔴 (03:05) User-provided shell-command helper trims captured stdout and resolves the exit code as code ?? 1.
🔴 (03:05) User-provided GHCR version-check path requires only 2 HTTP requests—token plus manifest—and does not download a blob.
🔴 (03:05) User-provided nightly download logic uses an exact nightly-{version} tag when applicable; otherwise it fetches the rolling :nightly tag.
🔴 (03:05) User-provided download handling accounts for Bun.file(path).writer() returning without immediately surfacing the file.
🔴 (03:05) User-provided file-visibility recovery is intended to self-heal without requiring the user to retry manually.
🔴 (03:05) User-provided file validation throws UpgradeError when the file “never becomes visible or stays empty.”
🔴 (03:05) User-provided fallback download helper returns null silently on any failure so its caller can fall back.
🔴 (03:05) User-provided upgrade source includes executeUpgradeHomebrew() and exported executeUpgrade().
🔴 (03:05) User-provided internal download dispatch retains the established download arguments plus source affinity and suppresses Biome’s lint/nursery/useMaxParams rule for that reason.
