Decision Framework
For each layer of the voice pipeline: the stakes, the questions to ask, the available options, and the tests to run before deciding.
This framework does not prescribe technology choices. It structures the thinking required before committing to an architecture. The same technical trade-offs (latency, sovereignty, cost) present differently depending on context: a validation MVP, a regulated deployment, or a commercial scale-up each call for distinct answers. The goal is to ask the right questions at the right time — and to run the tests that will let facts answer them.

This determines the trade-off between iteration speed and architectural solidity.
On the timing of decisions
Prioritize iteration speed over sovereignty. Cloud APIs allow validating product hypotheses without infrastructure. Accept the technical debt of vendor dependency.
Trade off between cost, sovereignty, and operational complexity. This is when to decide which layers deserve to be internalized, based on real data from the validation phase.
Architecture decisions made in the validation phase become structural constraints. Migrating a layer at scale costs 5–10× more than a well-considered initial decision.
