Taskbar Monitor Enhanced v1.7.8 — optional thermal warning sound

Taskbar Monitor Enhanced v1.7.8 - optional audible thermal warning

Temperature warnings

• Adds an opt-in Play Windows warning sound option under Settings > Alerts.
  New installations and upgrades default to sound off, unless you explicitly
  enable it. The existing Windows temperature notification preference remains
  separate and unchanged.
• When both Windows notifications and the sound option are enabled, a real
  CPU/GPU/disk temperature crossing requests Windows' current Exclamation sound.
  The existing per-device transition latch, 3 C hysteresis, ten-minute cooldown
  and user quiet hours/snooze continue to apply: no repeated sound every poll.
• Test warning sound in the same Settings page previews the Windows sound
  once on a deliberate click, without heating the CPU or moving thresholds.
• Uses the user's Windows sound scheme and system output volume. Sound can be
  muted/disabled by Windows, so a request log is not evidence a speaker was heard.
  The existing glass zero-alpha background and red hot-temperature text/charts
  are unchanged.

Existing safe upgrade

• One intentionally unsigned Setup, same per-user installation root.
  Exact SHA-pinned official v1.7.7 predecessor is supported transactionally,
  including the previously verified crash recovery of updater-owned .restore.
• Preserves user config/history/autorun, GPU/disk sensor services, and all
  existing themes, settings, focus and Start/fullscreen handling.
• No new driver; external signed PawnIO policy remains distinct from Setup.
• Physical AC-mains-loss testing is excluded by the owner; global machinewide
  singleton and independent security signing-lab claims are not made.
• Original reporter-specific WinRing0 SHA/download origin remains pending in
  GitHub Issue #6. Never disable or bypass Defender.

Status and evidence

• Released and accepted: immutable public v1.7.8 (exact source 9960a06), seven verified assets and supply-chain G16 PASS.
• Hosted Build and native Windows A/B Setup/crash-recovery tests PASSED. The owner installed official v1.7.8 in place from v1.7.7, preserving user config, Glass state and protected sensor services.
• On the owner PC, opt-in sound preview and natural CPU temperature-warning requests were observed with at least 10-minute spacing and zero recorded sound-play exceptions. A separate Windows audio-route and isolated Exclamation test confirmed a non-muted digital output signal; this is not proof of physically audible speaker sound.
• Actual on-screen Windows banner delivery has not been independently witnessed. External WinRing0 reporter sample provenance remains open in GitHub Issue #6. The installer is intentionally unsigned.
• The immutable RELEASE_NOTES_v1.7.8.md asset is a publication-time snapshot and still contains the superseded private-candidate status line; the completed release status and acceptance evidence above are authoritative. The original asset is retained byte-for-byte for provenance.
