BulletinPoller fetches the Pixel security bulletin index page on
its own HandlerThread with 5s/30s/2m/10m/30m bootstrap backoff,
then 24h steady cadence. The first <td>YYYY-MM-DD</td> match is
the latest published patch; newer-than-current dates flow through
PatchLevelManager.updateTo for validation + atomic write + resetprop.
Persists the last 10 attempts to last_bulletin_fetch.json (atomic
rename) with status, http_code, parsed_date, applied, and error
fields so operators can audit history without logcat.
Sepolicy rule appends TCP-socket allow rules for both ksu and
magisk source domains so HttpsURLConnection survives SELinux
enforcement on either root provider. Uninstall.sh cleans the
three new artifacts.
resetprop overrides for ro.boot.* props don't survive reboots. On
devices where the kernel doesn't set ro.boot.vbmeta.public_key_digest,
the fallback chain hit random generation on every boot, producing a
different RootOfTrust hash each time.
Added file-based persistence (boot_hash.bin, boot_key.bin) as a
fallback layer between TEE cache and random generation. Once a value
is determined from any source, it's written to disk and reused on
subsequent boots.
Verified on Redmi 14C: second boot reads from persistent file instead
of regenerating random bytes.
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.
