0% 100% decay

The progress bar indicates the "decay status" of the system version. If the corresponding CI build job fails, the system's decay status will reach 100% instantly. If the build job succeeds, the decay status is derived from the system's "last updated" timestamp. Thus, a system version is considered "decayed" if it has not been synchronized within the last two months.
