CyberMind-FR 55955867af feat(clients): persistent WG identity (APK) + Tor status in webext/APK (ref #683)
APK (0.4.0):
- FIX lost-referrer: persist the WG profile in app-internal filesDir and REUSE
  it. /wg/profile/new mints a fresh keypair each call and onboarding runs every
  boot, so the device kept re-keying → new sha256(pubkey) identity → stats reset
  each reboot. Now one stable identity across reboot/reconnect/restart.
  (Reinstall still wipes filesDir; allowBackup stays off for CSPN.)
- Silent root onboarding (CA system-store + native WG) already runs on boot
  (#538/#558); it now provisions the STABLE profile.
- Surfaces 🧅 kbin Tor-egress status after onboarding.

webext (0.1.5):
- popup shows a 🧅 Tor indicator (exit anonymised) next to the R3 dot,
  via the new public /wg/tor-status endpoint.

toolbox (2.7.5):
- public, kbin-safe GET /wg/tor-status {tor_mode,running,bootstrap,exit_ip}
  (mirrors /wg/r3-check; /admin/tor/* stays admin-gated). Verified live on kbin.

13 toolbox tests green. .xpi 0.1.5 built; .apk builds via build-android-apk.yml.

SecuBox Android ToolBox client (#531)

One-tap R3 onboarding for the VILLAGE3B cabine : install the CA, import the WireGuard profile, verify the tunnel, then open the live cartographie sociale. Replaces the manual Android tutorial.

Flow (manual path)

  1. Discover — scan the kbin QR or type the booth host (kbin.gk2.secubox.in).
  2. Install CA — downloads /wg/ca.crt, launches the Android cert-install intent (KeyChain.createInstallIntent).
  3. Import profile — downloads /wg/profile/new, hands the .conf to the WireGuard app via FileProvider + ACTION_VIEW.
  4. Verify — polls /wg/r3-check → "Tunnel R3 actif ✓".
  5. Live metrics — opens /social/me (cartographie sociale).

Root path — real zero-tap, fully automated (#538, #551, #558)

On a rooted device the app onboards with zero taps, two ways:

  • On launch — auto-detects root and runs the silent sequence immediately every launch (no gate), retrying reachability while WiFi/tunnel settle.
  • On boot — a BOOT_COMPLETED receiver starts a short foreground service (OnboardService) that runs the same silent sequence without opening the app, then stops. After one reboot the device self-onboards.

The Installation automatique (root) button remains as a manual re-trigger. Two interactions are mandated by Android and unavoidable for any app: the sideload install confirm ("install unknown apps") and the first-time superuser (Magisk/su) grant prompt. Everything after those is zero-tap. Steps:

  1. System CA install — downloads /wg/ca.pem, computes the OpenSSL subject_hash_old in pure Kotlin, and bind-mounts a populated copy of the trust store over /system/etc/security/cacerts (+ the conscrypt APEX path on Android 14), restoring the SELinux context (u:object_r:system_security_cacerts_file:s0). Every app trusts the cabine CA — not just user-CA opt-in apps. Reversible via umount.
  2. Native WireGuard — if the kernel has the WireGuard module + wg/ip, brings the tunnel up natively (ip link add … type wireguard + wg set), no WireGuard app required.
  3. Auto R3 verify — polls /wg/r3-check.

Fallback — if the kernel lacks WireGuard, the root path installs the system CA then hands off to the manual WireGuard-app flow (steps 35 above).

All root actions are gated behind the explicit tap — nothing runs as root without the operator choosing root mode on their own device. See RootShell.kt (su wrapper) and RootOnboard.kt (silent sequence).

Build

No Gradle wrapper jar is committed (text-only scaffold). CI builds it:

  • GitHub Actions build-android-apk.yml → debug APK artifact. Locally (with Android SDK + Gradle 8.9 + JDK 17):
cd clients/android-toolbox
gradle :app:assembleDebug      # app/build/outputs/apk/debug/app-debug.apk

Constraints (MVP)

  • Android 11+ restricts user CA trust ; the manual path launches the install intent + guides the confirm step. Browsers on the device need the CA trusted for the mitm R3 break — this is the known Android limitation on non-rooted devices. Rooted devices bypass it entirely via the system CA install (see Root path above).
  • The manual path imports the WireGuard profile via the official WireGuard app (no embedded tunnel) — most reliable, no extra native deps. The root path brings the tunnel up natively with the kernel module.
  • Debug APK is self-signed (sideload). Release signing (published fingerprint, served from the toolbox) is a follow-up needing a keystore secret in CI.

Tech

Kotlin + Jetpack Compose, minSdk 26 / targetSdk 34. API client is plain HttpURLConnection (no Retrofit/OkHttp) to keep deps + CI minimal.
