Properties
- architecture ↔ String
-
ABI name as the OS reports it: Android sends Build.SUPPORTED_ABIS
0("arm64-v8a"), Apple "arm64", Web "wasm32". Kept a string because no industry API enumerates ABIs — but the spelling is the OS's, not ours.getter/setter pair - availableMemoryBytes ↔ Int64
-
Free + reclaimable system RAM at snapshot time, in BYTES.
0 = UNKNOWN (the Web producer cannot read it). A consumer MUST NOT read
0 as "no memory left" and refuse to load.
getter/setter pair
- batteryLevel ↔ double
-
Remaining charge as a fraction of full. ABSENT is the ONLY encoding of
"unknown" — 0.0 means a flat battery, not an unreadable one. Producers
bridging through rac_device_registration_info_t (which uses a negative
sentinel) MUST map negative -> absent, never negative -> 0.
getter/setter pair
- batteryState ↔ BatteryState
-
ABSENT when the platform reports no battery at all; UNSPECIFIED when a
battery exists but its state could not be read. The C ABI member is
documented NULL-if-unavailable, which is why this stays

- totalMemoryBytes ↔ Int64
-

read ActivityManager.MemoryInfo.totalMem, not Runtime.maxMemory().
