shorecat_updater

Pure Dart patch updater for Shorecat. Checks for updates, verifies signatures, downloads resumable deltas, rebuilds artifacts and tracks boot success/rollback.

Flutter applications should use shorecat_code_push, which integrates this updater with the Android boot hook and first-frame reporting. This lower-level package is for custom hosts and tooling; it does not itself arrange for the Flutter engine to load a patched artifact.

See the architecture for the state machine, artifact format and signing contract.
