Observations

Android

Tested on Nexus 9 running Android 7.0
fresh install, no updates via deploy


deploy_uuid: "cca9d318978b0e8959d83876c8a10ead"


pathname: "/data/user/0/io.cordova.hellocordova/app_cca9d318978b0e8959d83876c8a10ead/index.html"


after an update via deploy


deploy_uuid: "cdc35956368f2c97c868f64c759e56de"


pathname: "/data/user/0/io.cordova.hellocordova/app_cdc35956368f2c97c868f64c759e56de/index.html"


iOS

Tested in iOS Simulator for 10.1
fresh install, no updates via deploy


deploy_uuid: "6f551a0e86ebc2cdf822405e5f17e9fb"


pathname: "/REDACTED_SIMULATOR_PATH/data/Containers/Data/Application/REDACTED_APP_UUID/Library/Application%20Support/6f551a0e86ebc2cdf822405e5f17e9fb/index.html"


after an update via deploy


deploy_uuid: "5af1a24a4f97e87e399c8489bb22ab3a"


pathname: "/REDACTED_SIMULATOR_PATH/data/Containers/Data/Application/REDACTED_APP_UUID/Library/Application%20Support/5af1a24a4f97e87e399c8489bb22ab3a/index.html"


Inferences


"deploy_uuid" string value is found precisely as-is within "pathname" string


"pathname" string value ends with "DEPLOY_UUID/index.html"
