What is the supported RustChain miner path on Android/Termux with Python 3.14?

[zaguzovmaksim0-hue]

During a real Android/Termux aarch64 dry-run for bounty #2271, the RustChain node health path worked (HTTP 200; 6/6 fingerprint checks passed), but the current Termux Python 3.14 environment exposed a PyNaCl compatibility/install problem before any mining, attestation, or enrollment was attempted.

For future Android/Termux users, what is the supported dependency path?

1. Is Python 3.14 intended to be supported, or should Termux miners pin a specific Python version?
2. Should PyNaCl/libsodium come from pip, Termux packages, or a documented source-build path on aarch64?
3. Would maintainers prefer a preflight dependency check that fails with an actionable Termux-specific message before the miner starts?
4. Is Android/Termux considered a supported mining environment, an experimental one, or only a diagnostic target?

I am asking for the canonical supported path rather than a local workaround, so the result can be reused in setup docs and unattended installs. Reproduction context is recorded in rustchain-bounties #2271. AI assistance disclosed.
