Android JNI callers could not read Build.VERSION, and valid explicit DEX classpaths hit unrelated 64 KiB JSON and 16-class limits before execution. Add an API 28 scalar version projection owned by the shared Dalvik Program/Runtime and sourced from the explicit Android property snapshot. JNI and DEX reads retain one field and heap identity; unsupported fields, writes and platform replacements remain explicit failures.

Keep the existing 64 KiB metadata limit while allowing the already documented 1 MiB DEX payload as hex, and separate the 16-image ceiling from a bounded 4096-class aggregate inventory. Preserve byte, memory, checksum and execution budgets. Synthetic fixtures exercise single/split classpaths, bounds, duplicate classes and malformed containers; no application inputs are included.

Validation:

• Version/wire revision cddcda3: Dalvik 38 passed; execution configuration 17 passed; Android JNI/Binder/property 325 passed, 324 platform skips; Linux process suite 477 passed, 283 skips; C API/CLI process suite 690 passed; SDK contract drift check passed.
• Final class-capacity revision c5bc4c0: complete JNI suite 252 passed, 252 platform skips; Binder/property 85 passed, 84 skips; Dalvik 38 passed. Unicorn and available HVF variants exercised.
• An attempted full Android suite was interrupted after unrelated HVF semaphore stress cases exhausted the 30-second deadline. Full Android coverage is not claimed.

This is a bounded version-state projection, not a boot framework, application context, class-loader or RegisterNatives implementation. Unknown application classes remain unsupported rather than being invented or assumed absent.
