| `platforms[].totals.installs` | Launches / successful installs in the window. |
| `platforms[].totals.failedInstalls` | Crashes / failed installs in the window. |
| `platforms[].totals.crashRatePercent` | `failedInstalls / (installs + failedInstalls) * 100`. Zero when no installs. |
| `platforms[].payload.launchAssetCount` | Number of assets the manifest references. |
| `platforms[].payload.averageUpdatePayloadBytes` | Mean bundle size for the window. |
| `platforms[].daily[]` | Per-day time series of installs and failed installs. |
