Before / After
Before
Answer-only AIEvery case spends the same expensive evidence budget.
Another evidence domain can appear without changing the action.
A recommendation can look finished even when no durable state changed.
Unsafe uncertainty has no explicit brake, owner, or verified handoff.
After
Trace-backed healthcare agentRoutes Attention Before RetrievalA served, versioned attention signal routes patient cases before retrieval while protecting at least 95% serious-case recall.
Changes Action When Evidence ChangesThe same patient receives assign_bed or divert when capacity changes; drug-safety evidence can turn discharge_plan into human_review.
Stops Before Unsafe ActionCross-domain uncertainty applies the brake, blocks autonomous disposition, and routes the case to a human review owner.
Acts Until Durable OutcomeAllowed actions change bounded operational state, record receiver ACK, and re-read the result instead of trusting a success message.
Rehearses Failure Before RolloutA simulated deployment contract checks five gates, injects false success, and requires rollback when outcome verification disappears.
