Alternatives and trade-offs

  • Naïve Ad-Hoc Implementation: Fast initial prototype; leads to technical debt, missing error recovery, and security vulnerabilities under load.
  • Production Architecture (Local Speech-to-Text with Whisper): High reliability, deterministic execution, and operational visibility; requires initial design discipline and test coverage.

Failure modes and misconceptions

  1. Un-Monitored Resource Contention: Omitting telemetry bounds or connection limits leads to unhandled system crashes.
  2. Missing State Recovery: Failing to implement graceful fallback mechanisms creates cascading system outages.
