v0.1.0 — first public release

Quantus Node for Android — v0.1.0

First public release.

An Android app that runs a regular (non-mining) Quantus Network full
node on your phone. It starts the bundled quantus-node binary as a
child process under a foreground service, syncs the mainnet chain
with pruning enabled, and shows status — peer count, best block,
sync progress — on a quiet dashboard. There is no wallet and no
mining; the app holds no keys to any funds. This build adds the
launcher icon: a bright core with concentric pulse rings on a dark
background, echoing the node's pulse.

Requirements

• Android 12 (API 31) or later, arm64 device
• Enough free storage for a pruned node database, and a Wi-Fi
  connection for the initial sync (it takes on the order of a
  couple of hours and downloads a few GB)

Verified device

• Confirmed working: Pixel 9a with GrapheneOS
• Other Android 12+ / arm64 devices are expected to work but are
  not yet verified. A manufacturer battery manager that kills
  foreground services may stop the node. Working reports via
  GitHub Issues are very welcome — they grow the verified list.

Install

1. Download quantus-node-v0.1.0.apk from this release.
2. Install it directly (you will need to allow installs from your
   browser / file manager for this source).
3. Open the app and press Start.

Updates install over the existing app: your node database,
display name and settings carry over. Do not uninstall first —
uninstalling erases the node data and the next start syncs from
genesis again.

This is the first release signed with the project's release key;
all future updates will carry the same signature.

Known limitations

• Two known vulnerabilities in transitive dependencies of the
  bundled node binary (zstd-safe 6.0.6 and crypto-bigint 0.5.5)
  have no fix available within their compatible version ranges
  yet and are waiting on upstream releases. See SECURITY.md.
• The concurrency fixes from the external audits (findings 2–7)
  were verified by code review and desk-checked interleavings;
  a deterministic on-device race-reproduction test has not been
  run, as noted in SECURITY.md.
• UI translations (9 languages) were produced by the maintainer
  with AI assistance and have not been reviewed by native
  speakers.
• State and block pruning are fixed at 256; very old history
  cannot be queried from this node.
