[AntigravityRuntime] failed to detect ${target} ${scanMode}

Error message

[AntigravityRuntime] failed to detect ${target} ${scanMode} version:

What it means

detectTargetVersion in src/services/antigravityRuntimeService.ts:37 wraps getAntigravityInstalledVersionInfo(target, scanMode) in try/catch. On rejection it warns '[AntigravityRuntime] failed to detect ${target} ${scanMode} version:' and returns false, signaling the runtime version is not detectable. The message is informational; the boolean false drives availability checks like currentQuickAvailable/alternateFullAvailable.

Solutions

1. Check the warn payload for the underlying invoke error to identify the failing target/scanMode.
2. Verify the Antigravity runtime for that target is installed and its executable path exists.
3. Retry after an install/upgrade completes, or trigger a rescan of installed versions.
4. Treat the returned false as expected when the target is intentionally not installed — it is not a hard failure.

Example fix

// before
return false; // after warn
// after
console.warn(...);
const fallback = await getAntigravityInstalledVersionInfo(target, 'full').catch(() => null);
return !!fallback?.version;

// Check installation before querying version info:
const installed = await invoke<boolean>('antigravity_is_installed', { target });
if (!installed) return false;

function hasVersionInfo(info: { version?: string | null } | null): info is { version: string } {
  return typeof info?.version === 'string' && info.version.length > 0;
}

try {
  const info = await getAntigravityInstalledVersionInfo(target, scanMode);
  return !!info?.version;
} catch (error) {
  console.warn(`[AntigravityRuntime] failed to detect ${target} ${scanMode} version:`, error);
  return false;
}

When it happens

Trigger: Calling any availability helper (currentQuickAvailable, alternateQuickAvailable, currentFullAvailable, alternateFullAvailable) when the backend version-info command rejects — runtime binary missing, install path unreadable, unsupported scan mode, or IPC failure.

Common situations: Antigravity not installed or partially upgraded so version metadata is absent; permission errors reading the install directory; stale cached install path after an update; running in a non-Tauri context where invoke fails.
