# Contract: Spoofing surface (LAB / user-visible)
## Settings
| Interface | Contract |
|-----------|----------|
| Secure setting | `allow_signature_fake` ∈ {`null`/`0`, `1`} |
| Readback | `adb shell settings get secure allow_signature_fake` |
| UI | Developer Options exposes enable/disable; OFF disables effect of grants |
## Permission
| Interface | Contract |
|-----------|----------|
| Permission name | `android.permission.FAKE_PACKAGE_SIGNATURE` |
| `pm list permissions` | Permission is listed (not “Unknown permission”) |
| Grant | Visible in `dumpsys package <pkg>` for authorized packages when user granted |
## PackageManager behaviour
When **toggle ON** and package **has grant** and **has** `meta-data fake-signature`
(or microG’s equivalent spoof path):
- Callers using legacy signature APIs and signing-certificate APIs MUST observe
the faked Google identity for that package (sufficient for microG Self-Check
“correct signature” and Play OAuth registration checks).
When **toggle OFF**:
- Effective spoofing MUST NOT occur (silent deny).
## Allow-list
| Package | Required |
|---------|----------|
| `com.google.android.gms` | yes |
| `com.android.vending` | yes |
| Other packages | denied unless explicitly added later under project policy |
## First-stack package registration
| Package | `pm path` expectation |
|---------|----------------------|
| `com.google.android.gms` | system_ext app path |
| `com.google.android.gsf` | system_ext app path |
| `com.android.vending` | system priv-app Phonesky path |
PRESIGNED APKs in the shipped image MUST verify with APK Signature Scheme v2/v3
(no post-sign strip).
## Location (documentation contract)
Quickstart MUST specify:
1. Open microG → Location
2. Enable network/Wi-Fi location as required by UI
3. Set service URL to BeaconDB (or documented successor), not MLS
No requirement to install UnifiedNlp backend packages.
