# 9.6 High-Consequence Systems

The LPP architecture becomes most restrictive as consequences become more difficult to reverse.

The governing principle is:

> **The more irreversible the consequence, the less acceptable it becomes to infer authority from capability, confidence, urgency, or convenience.**

High-consequence systems may include actions affecting:

* critical assets,
* sovereign systems,
* systemic infrastructure,
* large-scale financial state,
* legally irreversible commitments,
* or other T3 / T4 consequence environments.

#### Irreversible Action

The LPP general consequence model defines:

```
T3
=
Legally or operationally irreversible
```

and:

```
T4
=
Sovereign / asset-critical / systemic-risk
```

These classifications signal that ordinary low-assurance authorization assumptions are no longer sufficient.

#### Asset-Critical Systems

Asset-critical actions may include operations that can materially affect:

* financial assets,
* critical enterprise state,
* strategic resources,
* or other high-value systems.

The system should not infer legitimate authority from:

```
The AI has access.
```

or:

```
The action appears beneficial.
```

Instead, the governing state may require stronger authority structures.

#### Sovereign Systems

Sovereign environments introduce additional legitimacy questions.

Authority may depend on:

* jurisdiction,
* institutional origin,
* authorized responsibility,
* cross-system recognition,
* or other sovereign constraints.

The general Authority Object model includes jurisdictional scope and supports the concept of stronger requirements for T4 authority.

GitBook v2.0 does not define one universal sovereign deployment architecture.

It establishes the constitutional requirement that sovereign authority cannot be generated by the AI execution system itself.

#### Systemic Risk

A locally bounded action may create system-wide consequence.

High-consequence deployment therefore must consider not only individual action properties but whether the action:

* affects shared infrastructure,
* propagates across systems,
* changes systemic state,
* moves critical assets,
* or creates difficult-to-reverse cascading consequence.

#### Non-Compensatory Governance

High-consequence systems make the non-compensatory principle especially important.

If:

```
AuthorityValid = FALSE
```

then:

```
Confidence = HIGH
```

does not repair the failure.

Likewise:

```
ScopeValid = FALSE
```

cannot be compensated by:

```
Expected Utility = HIGH
```

and:

```
Revoked = TRUE
```

cannot be compensated by:

```
Urgency = CRITICAL
```

The core rule is:

```
Failed Mandatory Constitutional Predicate
        ↓
No ADMIT
```

#### Stronger Authority Requirements

The general T0–T4 model explicitly associates higher consequence with stronger authorization requirements.

Depending on the applicable profile, stronger requirements may include combinations of:

* multiple signatures,
* independent authority sources,
* stronger verification,
* shorter validity windows,
* continuous revocation,
* independent Artifact verification,
* or stronger Control Plane / Execution Plane separation.

The exact combination is domain-specific.

#### Stronger Enforcement Topology

The CP / EP Separation Model defines increasing assurance tiers:

```
Tier A
Logical Separation
```

```
Tier B
Strong Enterprise Separation
```

```
Tier C
Sovereign / High-Assurance Separation
```

```
Tier D
Optional Physical Enforcement
```

Higher tiers may introduce:

* independent administrative domains,
* dual or multi-party Permit issuance,
* stronger revocation channels,
* attested workloads,
* or hardware-mediated execution gating.

These are deployment levels.

They are not claims that the current MVP implements Tier C or Tier D.

#### Fail-Closed

High-consequence systems should not treat an unresolved mandatory governance state as implied permission.

```
Authority Unknown
≠
Authority Valid
```

```
Verification Unavailable
≠
MATCH
```

```
Permit Unverifiable
≠
Permit Valid
```

The architecture therefore favors:

```
Unresolved Mandatory State
        ↓
Restrict / Defer / Deny / Collapse
```

rather than:

```
Unresolved Mandatory State
        ↓
Execute anyway
```

#### Interruptibility

Where the action unfolds over time, stronger deployments may require continuous admissibility and the ability to respond to:

* revocation,
* material mutation,
* policy change,
* or changed authority state

before the irreversible consequence occurs.

#### High-Consequence Non-Claim

LPP does not claim that classification as T3 or T4 automatically makes a deployment safe.

T-classification identifies the consequence level and the need for stronger governance.

Actual safety still depends on the surrounding systems, including:

* runtime security,
* functional safety,
* physical controls,
* infrastructure security,
* human governance,
* and domain-specific compliance requirements.

### Cross-Domain Deployment Model

The six deployment profiles use different domain objects and failure conditions, but the canonical architecture remains recognizable.

| Domain           | Example Authority Basis          | Example Consequential Action  | Primary LPP Concern                     |
| ---------------- | -------------------------------- | ----------------------------- | --------------------------------------- |
| Multi-Agent      | Principal / delegated authority  | Cross-agent execution         | Delegation and intent drift             |
| Enterprise       | Business / workflow authority    | Record or workflow mutation   | API access vs action authority          |
| Financial        | Financial Authority Object       | Trade / transfer / settlement | Financial pre-execution admissibility   |
| Cyber            | Incident / operator authority    | Infrastructure mutation       | Scope and privilege escalation          |
| Physical AI      | Operator / device authority      | Physical movement / actuation | Capability vs physical authority        |
| High-Consequence | Enhanced institutional authority | T3 / T4 action                | Irreversibility and systemic legitimacy |

The domain terminology changes.

The constitutional ordering does not:

```
Authority
        ↓
Authorized Intent
        ↓
Specific Action Candidate
        ↓
Domain Consequence Classification
        ↓
LPP Admission
        ↓
Execution Permit
        ↓
Domain Execution Boundary
        ↓
External Effect
        ↓
Reconstructable Evidence
```

### Deployment Profile Summary

LPP does not assume that all AI actions are governed identically.

It assumes that all consequential AI actions require a legitimate basis appropriate to their domain.

The central distinctions remain:

```
Multi-Agent:
Delegation
does not create new authority.
```

```
Enterprise:
API access
does not establish business authority.
```

```
Finance:
Financial capability
does not authorize asset movement.
```

```
Cyber:
Privileged access
does not establish remediation authority.
```

```
Physical AI:
Physical capability
does not establish authority to act.
```

```
High-Consequence:
Urgency, confidence, and utility
cannot compensate for failed legitimacy.
```

The cross-domain principle is therefore:

> **The implementation environment may change. The requirement that authority precede consequential execution does not.**
