01 — Le problème

Le problème

Emulators don't faithfully reproduce behavior under the constrained memory/CPU of a real low-end phone.

A qui cela s'adresse

Any company whose app/web must work on low-end Android phones (markets where most real users have limited hardware) and has no hardware of its own to test on.

03 — Ce qui s'exécute

Ce qui s'exécute

  • The worker runs the check on a real low-end Android device (never an emulator): device profile, load/cold-start timing, PSS memory, jank frames, and any FATAL EXCEPTION/ANR observed via a logcat window.
  • Fault profiles covered by the harness: network_loss, adb_loss, sim_anomaly, reboot, ui_change (service_restart is not yet registered — apply()/restore() unimplemented in fault_injection.py, a pre-existing gap).
  • No formal backtests have run against the real device yet (BLOCKED_HARDWARE) — the probe exists but has 0 measured runs today.

06 — Autonomie

Autonomie

Designed to run unattended end to end. Not yet measured: zero real backtest runs against the physical device today (BLOCKED_HARDWARE) — the check_type and probe exist, but autonomy has no measured figure yet.

Preuve

Aucune allégation publiable pour ce service pour le moment — les backtests et les preuves en conditions réelles sont encore en cours de mesure. Voir les limites connues ci-dessous.

08 — Limites connues

Limites connues

  • No formal backtests measured yet.
  • Measured today on a MID-range device until a real low-end device is added to the pool: every run honestly declares the observed device tier and whether it meets the minimum tier — a low-end result is never simulated.
  • Depends on the internal_research/low-end physical pool, currently limited in size.
  • Crash detection is a best-effort logcat-window scan, not a full stack-trace parser.

Questions sur ce service

Not yet. No formal backtests or real-world samples exist yet, so it stays fail-closed until that changes.
