Some upstream keybox sources inject HTML comments inside PEM
certificate blocks. BouncyCastle's PEMParser chokes on these
non-base64 lines, silently failing to load the keybox.
Filter lines starting with <!-- in trimLines() before the content
reaches the PEM parser.
When a config file is deleted, the event handler sets file=null but
then force-unwraps it with file!! in the when block, crashing the
FileObserver thread. All subsequent config change notifications are
silently lost.
Replace force-unwrap with safe call, log a warning on deletion.
Fork-based supervisor ensures the interceptor process survives crashes.
pingBinder() liveness check on pre-transact returns DEAD_OBJECT to
callers when interceptor is down, preventing real TEE state from leaking
during the restart window.
action.sh clears persistent key storage via KSU Action button.
uninstall.sh kills daemon processes and removes module artifacts while
preserving target.txt and keybox configuration.
