Core Architecture
DigiEmu Core separates application behavior from deterministic verification state.
Conceptual pipeline
Section titled “Conceptual pipeline”Application ↓Explicit Input ↓Snapshot ↓Canonical State ↓Cryptographic Identity ↓Bundle ↓Replay ↓Verification ↓EvidenceDesign principles
Section titled “Design principles”Explicit state
Section titled “Explicit state”Integrity-relevant behavior should depend on explicit inputs rather than hidden mutable state.
Canonical representation
Section titled “Canonical representation”Equivalent state must be represented consistently before a deterministic identity is derived.
Deterministic verification
Section titled “Deterministic verification”For fixed referentially closed inputs, verification should produce equivalent verification outcomes.
Replayability
Section titled “Replayability”Preserved bundles allow state to be reconstructed independently from the original application execution.
Separation of concerns
Section titled “Separation of concerns”Core verifies properties of preserved state.
It does not by itself determine:
- whether a real-world claim is true
- whether an actor is trustworthy
- whether an action was authorized
- whether a decision was legally compliant
Those responsibilities belong to higher governance and application layers.
Trust boundary
Section titled “Trust boundary”The Core verification boundary begins where explicit state enters the deterministic pipeline.

Section titled “Why this architecture matters”Traditional application logs describe what software says happened.
DigiEmu Core instead creates artifacts that can be independently inspected, reconstructed and verified.
