Why Glacis exists
| Scope and ownership | Name the use, its boundaries and its owner |
|---|---|
| Charter and controls | Set the checks and the action to take |
| Monitoring | Investigate changes in behavior |
| Evidence for review | Keep a verifiable record of what happened |
Your team should be able to interpret the evidence without becoming AI experts
Institutional use
Glacis is an approved evaluator under a signed agreement with Utah’s Office of Artificial Intelligence Policy
The program calls for signed records showing that specified safety checks ran
Ambient-scribe research
Transcript, paraphrased
The patient reports a pacemaker recommendation and says she does not want one
What the draft omits
Neither the recommendation nor the refusal appears in the note
Check the missing treatment decision before signing the note
Encounter 2 · Paraphrased research example · Offline evaluation
Ambient-scribe research
Ten transcript–draft pairs · “Supported” means both reviewing model families agreed
| Control | Raised | Supported | Rejected | Unresolved |
|---|---|---|---|---|
| Clinical omissions | 30 | 24 | 2 | 4 |
| Clinical grounding | 1 | 1 | 0 | 0 |
| Measurement integrity | 1 | 1 | 0 | 0 |
Overview · Product demonstration
See which checks are in place and how they are configured to act
Review recorded requests, findings and blocked responses
See which receipts have a checked signature and proof of inclusion in the log
Drift · Ambient Scribe Co demonstration
This control’s scores rose above the baseline
The change detector crossed its alert threshold
Open the linked receipt to examine the individual checks and their results
Receipts · Recorded product demonstration
A receipt is a signed record of the checks and outcome for one request
| Case | Control result | Delivery | What happened | |
|---|---|---|---|---|
| 1 | Allowed | Released | No enabled check reported a finding | |
| 3 | Flagged | Released | Privacy found identifiers; the reply reached the caller unchanged | |
| 5 | Blocked | Withheld | An input term rule matched “ignore your charter” |
The Charter determines the action when a configured check triggers
Receipts · Verification
Checks that the signed content has not changed and matches a known signing key
Checks that this record appears in the signed log supplied with it
Checks the signing key against the expected deployment
Shared oversight
| Clinical AI lead | Which finding needs clinical review? |
|---|---|
| Security | Which control ran, and what action followed? |
| Governance and audit | Which policy applied? |
| Risk and operations | Who acts, and what closes the issue? |
Next step
Bring the people who will review it day to day
Which decisions should your team be able to make without calling an AI specialist?
Study design
supplied transcripts
with existing SOAP drafts
Run three controls with each of three model backends
Verify its source evidence and whether it meets the control’s rule before emitting an alert
The other two model families assess each alert; both must support it for a “supported” result
Backends: GPT-5.6 Sol, Gemini 3.1 Pro Preview and Claude Opus 5
Nine pairs formed the primary analysis; Sample 1 mixed encounters and produced no selected alerts
Research and recorded product behavior
| Clinical research | Recorded staging run | |
|---|---|---|
| Checks | Omissions, grounding and blood-pressure integrity | Input term rules Input and output privacy |
| Setting | Offline evaluation of supplied transcripts and existing drafts | Five synthetic requests with prepared provider replies |
| Evidence | Findings and model-family review | Actual enforcement, caller results and signed receipts |
The clinical controls were evaluated offline; their Portal integration is illustrative
Recorded Case 4
Synthetic input, excerpt
“today’s visit is for follow-up on your hypertension and diabetes”
Prepared reply, excerpt
“BP 130/80, HR 72, RR 16, Temp 98.6”
The reply added measurements the input did not supply
The privacy and term-rule checks reported no finding
This Charter did not assess clinical correctness or factual support
Ambient Scribe Co · Supporting detail
| Check | Recorded score | Recorded result |
|---|---|---|
| Content safety | 0.10511655 | Allowed |
| Prompt attack | 0.9999404 | Flagged |
The overall receipt is Flagged / Released
The drift view describes a change in scores; the receipt shows each check’s decision and the delivery outcome
During the live Drift walkthrough
Drift means check results
are changing over time
The reference period or expected pattern used for comparison
How often a check flags, relative to the requests it assessed
A change can reflect different inputs, settings or model behavior; individual cases help explain it
These terms guide the walkthrough; the five captured requests do not demonstrate drift detection or performance
The priority from our last conversation
Build the team’s ability to review AI use without requiring everyone to become an AI expert
A clear explanation of what each result tells them, what it leaves open and when to involve a specialist
Whether Overview, Drift and Receipts explain the technical evidence in language the team can use
