**Problem** After #31109 and #31865, it's still possible to get locked in state `EXISTING_CLIENTS_ONLY`, without any possibility to get out (even by pushing new updates on the server). More specifically, if control doc `/latest` of `ngsw:/:db:control` once gets a bad value, then the service worker will fail early, and won't be able to overwrite `/latest` with new, valid values (the ones from future updates). For example, once in this state, URL `/ngsw/state` will show: NGSW Debug Info: Driver state: EXISTING_CLIENTS_ONLY (Degraded due to failed initialization: Invariant violated (initialize): latest hash 8b75… has no known manifest Error: Invariant violated (initialize): latest hash 8b75… has no known manifest at Driver.<anonymous> (https://my.app/ngsw-worker.js:2302:27) at Generator.next (<anonymous>) at fulfilled (https://my.app/ngsw-worker.js:175:62)) Latest manifest hash: 8b75… Last update check: 22s971u ... with hash `8b75…` corresponding to no installed version. **Solution** Currently, when such a case happens, the service worker [simply fails with an assertion][1]. Because this failure happens early, and is not handled, the service worker is not able to update `/latest` to new installed app versions. I propose to detect this corrupted case (a `latest` hash that doesn't match any installed version) a few lines above, so that the service worker can correctly call its [already existing cleaning code][2].
