Systemless Magisk controller for automatic, reversible Android 16 network-profile changes. It does not modify /system, /system_ext, /vendor, RIL, modem firmware or framework.

Scope

Backend: Android 16 cmd phone set-allowed-network-types-for-users.
Target: one slot at a time, default slot 0.
HIGH: LTE + UMTS/HSPA + GSM families.
LOW: UMTS/HSPA + GSM families.
Safety: capture/restore, active-call refusal, result verification and event log.
No Xposed or Vector. The companion APK source is included under app/; the module zip includes it only after the AOSP app build produces system/app/IntelliRAT/IntelliRAT.apk.

The binary masks are derived from the LOS23/A16 TelephonyManager constants: network type bits are 1 << (NETWORK_TYPE - 1), with LTE CA normalized to LTE. They must be treated as target-build data, not a universal Qualcomm constant.

Install on GOLDEN only

Do not install this in the production ROM or on LAB yet. Build a Magisk module zip with scripts/build-intellirat-module.sh, install it on GOLDEN with a test SIM, and keep the known-good ROM available. GOLDEN now detects the inserted test SIM as LOADED on SIMon mobile.

After Magisk loads the module:

su -g 2000 -G 2000 -c /system/bin/intellirat status 0
su -g 2000 -G 2000 -c /system/bin/intellirat capture 0
su -g 2000 -G 2000 -c /system/bin/intellirat --dry-run high 0
su -g 2000 -G 2000 -c /system/bin/intellirat high 0
su -g 2000 -G 2000 -c /system/bin/intellirat status 0
su -g 2000 -G 2000 -c /system/bin/intellirat low 0
su -g 2000 -G 2000 -c /system/bin/intellirat restore 0

capture must be run before a transition. restore uses the captured user mask and does not guess a stock mode. events.log is stored under /data/local/tmp/intellirat/. The prototype uses the root-owned shell group for this small network-mask state because MagiskSU drops DAC capabilities for su commands; no credentials or private data are stored.

When the companion APK is present, launch IntelliRAT from the app drawer. It shows the current backend result, slot selector, automatic toggle, delay, foreground-package exceptions, capture/HIGH/LOW/restore buttons and a persistent status notification with quick actions. The automatic policy uses lock delay, unlock restoration and a safe call guard.

Not implemented yet

traffic protection
multi-SIM/eSIM UI and subscription discovery
Quick Settings tile

The current automatic policy is deliberately limited to Keyguard lock state, a configurable delay and explicit foreground-package exceptions. Wi-Fi, battery, traffic and multi-SIM rules remain disabled until their real device behavior is specified and tested with calls, IMS, SMS, data and signal loss.
