System registry
Separate the powers
The system chain exists to prevent observation, modelling, evaluation, coordination, enforcement, and governance from collapsing into one opaque operator.
DI-SYS-LOOKOUT · observation
Lookout
specified
DI-SYS-LOOKOUT · observation
Lookout
Observe external reality, acquire evidence, and preserve the provenance of each observation.
Authority boundary
Observation authority only; Lookout may record evidence but cannot evaluate, authorise, coordinate, or enforce action.
Dependencies
No system dependency declared.
Inputs
- External events and conditions
- Submitted records and source material
Outputs
- Provenance-bearing evidence records
- Observation gaps and acquisition warnings
Governing publications
DI-SYS-BLACKLINE · modelling
Blackline
defined
DI-SYS-BLACKLINE · modelling
Blackline
Convert evidence into explicit models of system state, uncertainty, relationships, and plausible trajectories.
Authority boundary
Modelling authority only; Blackline represents reality but cannot treat its model as reality or select an authorised outcome.
Dependencies
Lookout
Inputs
- Provenance-bearing evidence records
- Declared modelling assumptions
Outputs
- Versioned system-state models
- Uncertainty and contradiction registers
Governing publications
DI-SYS-VERDICT · evaluation
Verdict
defined
DI-SYS-VERDICT · evaluation
Verdict
Evaluate claims, options, policies, and consequences against declared criteria and authority constraints.
Authority boundary
Evaluation authority only; Verdict may produce a reasoned assessment but cannot authorise itself or execute the selected action.
Dependencies
Blackline · Codex
Inputs
- Versioned system-state models
- Evaluation criteria and authority references
Outputs
- Reasoned evaluations
- Conditions, dissent, and unresolved uncertainty
Governing publications
DI-SYS-STRUCTURA · coordination
Structura
specified
DI-SYS-STRUCTURA · coordination
Structura
Translate authorised decisions into coordinated actors, dependencies, tasks, interfaces, checkpoints, and evidence obligations.
Authority boundary
Coordination authority within an approved decision envelope; Structura cannot expand the originating mandate or perform enforcement.
Dependencies
Verdict · Codex
Inputs
- Authorised decisions and conditions
- Available actors, capabilities, and dependencies
Outputs
- Governed execution plans
- Dependency, checkpoint, and handoff records
Governing publications
DI-SYS-BALF · enforcement
Balf
prototyped
DI-SYS-BALF · enforcement
Balf
Enforce authorised boundaries, validate interventions, and preserve consequential state transitions in an auditable ledger.
Authority boundary
Narrow enforcement authority granted by an explicit mandate; Balf must refuse ambiguous, stale, or unauthorised intervention.
Dependencies
Structura · Codex
Inputs
- Governed execution plans
- Authorised intervention requests
Outputs
- Accepted or refused interventions
- Auditable enforcement and state-transition records
DI-SYS-CODEX · governance
Codex
specified
DI-SYS-CODEX · governance
Codex
Govern canonical definitions, operators, rules, authority references, evidence classes, and admissible interpretations across the system chain.
Authority boundary
Reference authority within each published scope; Codex constrains interpretation but does not manufacture evidence or legitimate its own authority.
Dependencies
No system dependency declared.
Inputs
- Approved doctrine and authority sources
- Versioned amendments and decision records
Outputs
- Canonical rules and definitions
- Conformance and supersession relationships
Structural rule
No layer may silently absorb another.
Observation is not evaluation. A model is not reality. Evaluation is not authorisation. Coordination is not enforcement. Enforcement is not self-legitimating. Codex is not evidence that its own rules are correct.
