The 2026 development
Heartbeat Thinking let voice agents begin reasoning and tool execution from partial transcripts.
The governance gap
Acting on a partial transcript is acting before the intent is complete. The faster the agent, the more important it is to separate speculative preparation from an irreversible action.
Where CAIN-42 fits: Moat 5 — Predictive Trust & Blast Radius
Core question: What could happen before we let it happen? Pre-execution analysis of reach, exposure and consequence, including simulations.
Allow speculative computation, but gate external effects on a completed-intent check. A partial transcript may warm a cache; it may not send the email or move the money.
How the wiring works
- Classify work as speculative preparation or consequential effect.
- Run preparation freely against the partial transcript.
- Require a completed-intent boundary before any external effect.
- Record the transcript state that authorised the effect.
What is real today
PROPOSED A design mapping only. No dedicated implementation exists yet; do not buy this as a finished control.
There is no voice or streaming-transcript implementation in this repository. The gating design is portable; the latency result is not ours.
