AudioShare USB v3.0.0-rc.3

AudioShare USB v3.0.0-rc.3

Third public release candidate of the portable Windows-to-Android USB audio
product. The downloadable ZIP remains self-contained and runs without an
installer or administrator access in the normal case.

Reliability fixes

• Embeds and cryptographically verifies the permanently signed Android
  1.0.0-rc.3 companion (version code 6).
• Fixes a reproduced Android watchdog bug where intentionally dropped
  live-edge audio could make a later silent period look stalled.
• Gives transient stale Bluetooth/wired routes a bounded recovery window while
  reasserting the built-in phone speaker.
• Applies the ordinary-performance compatibility fallback to the entire
  AudioTrack setup, not only construction.
• Prevents a new Android receiver session from overlapping an old playback
  worker that has not conclusively stopped.
• Persists an exact, owner-validated ADB forward journal. On the next start,
  AudioShare removes only a matching stale device + port + socket mapping;
  it never uses broad adb forward --remove-all cleanup.
• Classifies known focus, route, protocol, package, and compatibility failures
  as terminal until user/environment action instead of repeating frustrating
  automatic retries.
• Adds bounded exponential backoff and diagnostics for the optional ADB device
  tracker while retaining periodic device polling.

Better “connected but silent” diagnostics

• Shows a visible warning when Android media volume is muted or very low.
• Reports Windows captured frames, current peak/RMS signal, and time since the
  last non-silent sample.
• Reports Android written frames, cumulative playback-head progress, progress
  ages, play state, and actual performance mode using a backward-compatible
  extension of the version-1 STATS message.
• Reports the shared ADB server executable/version/mDNS status when supported,
  without killing or silently reconfiguring another tool's ADB server.

Beginner and AI-assistant guidance

• Adds the exact creator credit: created by Shayan SalehiRad in the Windows
  app header.
• Adds llms.txt and a dedicated AI setup brief that tell assistants to guide
  ordinary users through the portable Windows ZIP—not cloning, Android Studio,
  Flutter, or Gradle.
• Includes the beginner and AI setup documents inside the portable ZIP.
• Clarifies Developer Options, USB debugging authorization, data-cable,
  extraction, companion installation, auto-connect, media-volume, and safe
  troubleshooting steps.

Verification boundary

The complete path was previously heard working very well on a Samsung Galaxy
A52s / Android 14 with global capture and zero visible drops in the diagnostic
snapshot. RC3 passes Android unit/lint/build, Flutter analysis/tests, MSVC native
protocol and integration checks, portable package verification, and hosted CI.
The exact RC3 build still remains a prerelease until the documented ten-minute
screen-off, repeated reconnect, measured latency, restricted-PC, and two-hour
physical-device gates are completed.
