Emerging Architecture Patterns

Decision sidecar

A typed judgment service sits beside ordinary code; code owns effects and safety boundaries.

• Evidence: source 1, source 2, source 3, source 4
• Caveat: The extra network hop must beat a local rule or classifier.

Cascade router

A cheap decision chooses whether to use rules, a small model, a premium model, a specialist, or a human.

• Evidence: source 1, source 2, source 3
• Caveat: Bad routing can erase all cost savings through failures and retries.

Confidence gate

Automation proceeds above a threshold; ambiguous cases go to another check or a person.

• Evidence: source 1
• Caveat: Thresholds require workload-specific calibration and monitoring.

Parallel decision matrix

One state is evaluated against many named questions, replacing repeated prompt/parse cycles.

• Evidence: source 1, source 2
• Caveat: Accuracy and question interactions under large batches remain unknown.

Probabilistic predicate + deterministic action

Jev supplies fuzzy predicates while TypeScript, policies, and workflows execute constrained actions.

• Evidence: source 1, source 2
• Caveat: Incorrect predicates are still operational errors even when outputs are valid.

Decision quorum

Multiple typed judgments are aggregated through voting or confidence-aware stopping.

• Evidence: source 1
• Caveat: Calling the same model repeatedly may produce correlated rather than independent evidence.
