Architecture & Telemetry Notes

Browser-Driven Polling: Polling occurs strictly within the active browser/OBS session. When the overlay tab is closed, all polling stops immediately without consuming background cron or daemon resources.

Automated Disk Space Cleanup: Temporary telemetry caches and de-duplication states in cache/reactions/ are cleared on a rolling 30-minute expiration window to ensure zero disk bloating.

Race-Grade vs. Ledger-Grade: YouTube mobile apps throttle rapid taps before transmitting telemetry. Telemetry represents live viewer energy and bursts (arcade race-grade), not an exact audited financial ledger.
