TrustGate Micro Engine Catalog
Part 1 — Foundations
1. Purpose
The TrustGate Micro Engine Catalog defines the constitutional model governing every TrustGate engine and micro-engine within the ZAYAZ platform.
It specifies:
- what TrustGate engines are;
- how micro-engines are identified;
- how execution responsibility is assigned;
- how engines participate in validation, trust, attestation, replay, federation, and intelligence;
- how runtime lineage is preserved;
- how engines remain governed, explainable, replayable, and auditable.
The catalog is the authoritative specification for TrustGate runtime components.
2. Scope
This specification governs:
- major TrustGate engines;
- TrustGate micro-engines;
- execution contracts;
- engine responsibility boundaries;
- runtime orchestration;
- telemetry requirements;
- replay responsibilities;
- validation participation;
- trust contribution;
- attestation contribution;
- federation participation;
- AI and Trust Intelligence interaction.
Implementation details may vary, but constitutional engine behaviour shall remain consistent.
3. Constitutional Principle
Every TrustGate execution capability shall be governed by an explicit engine identity.
No runtime capability shall exist anonymously.
Every executable component shall be traceable through:
EID
↓
MEID
↓
CMI
↓
Runtime Execution
↓
Telemetry
↓
Replay
4. Engine Identity Layers
TrustGate distinguishes three execution identity layers.
| Layer | Identifier | Purpose |
|---|---|---|
| Major Engine | EID | Identifies a large platform engine or runtime domain. |
| Micro-Engine | MEID | Identifies a fine-grained executable capability. |
| Managed Artifact | CMI | Identifies the governed implementation artifact registered in ZAR. |
These identifiers are complementary.
They shall not be merged.
5. EID — Engine Identifier
An Engine Identifier identifies a major TrustGate execution domain.
Examples include:
EID-TRUSTGATE
EID-VALIDATION
EID-REPLAY
EID-FEDERATION
EID-ATTESTATION
EID-TRUST-INTELLIGENCE
EIDs coordinate runtime behaviour.
They do not replace micro-engine identities.
6. MEID — Micro Engine Identifier
A Micro Engine Identifier identifies a specialized executable component.
Examples include:
MEID_VALIDATE_SIGNAL_STRUCTURE
MEID_VALIDATE_CSI_BINDING
MEID_GENERATE_TRUST_VECTOR
MEID_VERIFY_ATTESTATION_SIGNATURE
MEID_REPLAY_VALIDATION_CHAIN
MEID_EXPORT_FEDERATION_PACKAGE
MEIDs represent operational responsibility.
Each MEID shall perform one clearly bounded function.
7. CMI — Canonical Managed Identifier
CMI identifies the governed artifact implementation resolved through zar.cmi_registry.
CMI is used for:
- compilation;
- deployment;
- dependency resolution;
- artifact governance;
- runtime lineage;
- ZAMG workflows;
- replay reconstruction.
CMI is not the same as CMID.
8. CMID Distinction
CMID means Canonical Metric Identifier.
CMID identifies measurable platform metrics, columns, facts, and sustainability data points.
CMI identifies managed artifacts such as engines, micro-engines, workflows, and computational components.
| Identifier | Meaning | Governs |
|---|---|---|
| CMI | Canonical Managed Identifier | Artifacts and components |
| CMID | Canonical Metric Identifier | Metrics and data points |
TrustGate engines primarily use CMI.
They reference CMIDs only when validating or processing metric-bearing signals.
9. Relationship to CIA
The Micro Engine Catalog adopts the Canonical Identifier Architecture.
CIA governs:
- EID;
- MEID;
- CMI;
- CSI;
- USO ID;
- VRID;
- TOID;
- TVID;
- TAID;
- TIID.
Every engine interaction shall preserve canonical identity.
10. Relationship to CPA
The Micro Engine Catalog adopts the Canonical Persistence Architecture.
CPA governs how engine definitions, runtime executions, telemetry, lineage, replay artifacts, and trust artifacts are persisted.
Micro-engines may execute logic, but persistence shall remain governed by canonical registries.
11. Relationship to CALM
Engines and micro-engines are governed artifacts.
They therefore participate in CALM lifecycle governance.
Typical lifecycle states include:
Draft
↓
Approved
↓
Published
↓
Operational
↓
Deprecated
↓
Retired
Runtime execution shall never modify engine definitions.
12. Relationship to CIR
Every engine and micro-engine may enforce one or more constitutional invariants.
Micro-engines shall declare:
- invariant families enforced;
- validation rules executed;
- replay obligations;
- telemetry obligations;
- failure policies.
CIR remains the authoritative invariant registry.
13. Position within the TrustGate Architecture
Micro-engines operationalize TrustGate constitutional specifications.
Signal Catalog
↓
Validation Rule Registry
↓
Trust Model
↓
Attestation Catalog
↓
Replay Specification
↓
Federation Profiles
↓
Micro Engines
Specifications define constitutional behaviour.
Micro-engines execute that behaviour.
14. Runtime Execution Philosophy
TrustGate follows a deterministic micro-engine architecture.
Every micro-engine shall be:
- narrowly scoped;
- independently governed;
- independently versioned;
- observable;
- replayable;
- testable;
- explainable.
Micro-engines shall not contain hidden constitutional logic.
15. Relationship to Validation
Validation micro-engines execute validation rules.
They reference:
- VRID;
- CSI;
- USO ID;
- CMI;
- TG-VRES;
- VEVID.
Validation logic is governed by the Validation Rule Registry.
Micro-engines execute rules but do not define constitutional validation semantics.
16. Relationship to Trust
Trust micro-engines produce or update trust artifacts.
They may generate:
- Trust Objects;
- Trust Vectors;
- Trust Status;
- Operational Flags.
Trust semantics are governed by the Trust Model.
Micro-engines execute trust computation under governed policies.
17. Relationship to Attestation
Attestation micro-engines support creation, verification, signing, publication, revocation, and federation of TG-ATTEST artifacts.
They may reference:
- TAID;
- TG-VRES;
- VEVID;
- TOID;
- TVID;
- cryptographic metadata.
Attestation semantics are governed by the TrustGate Attestation Catalog.
18. Relationship to Replay
Replay-capable micro-engines shall support deterministic reconstruction of historical execution.
Replay requires preservation of:
- EID;
- MEID;
- CMI;
- configuration version;
- policy version;
- runtime inputs;
- telemetry;
- produced artifacts.
Replay behaviour is governed by the TrustGate Replay Specification.
19. Relationship to Federation
Federation micro-engines support cross-domain assurance exchange.
They may perform:
- federation package creation;
- attestation verification;
- exchange policy validation;
- trust propagation;
- revocation processing.
Federation behaviour is governed by TrustGate Federation Profiles and EGFS.
20. Relationship to Trust Intelligence
Micro-engines may consume or produce Trust Intelligence.
They may:
- consume TIIDs;
- generate TG-INTEL candidates;
- detect anomalies;
- produce explainability;
- recommend governance actions.
AI and intelligence outputs shall never modify canonical artifacts directly.
21. Runtime Telemetry
Every production micro-engine shall emit TrustGate telemetry.
Telemetry shall include:
- EID;
- MEID;
- CMI;
- execution timestamp;
- runtime status;
- input artifacts;
- output artifacts;
- duration;
- failure classification;
- replay references.
Telemetry shall be persisted in:
zar.trustgate_telemetry_event
22. Engine Responsibility Boundary
Each micro-engine shall have exactly one primary constitutional responsibility.
A micro-engine may support multiple workflows, but its architectural responsibility shall remain bounded.
Examples:
| Micro-Engine | Responsibility |
|---|---|
| MEID_VALIDATE_CSI_BINDING | Validate CSI binding correctness |
| MEID_VERIFY_TAID_SIGNATURE | Verify attestation signature |
| MEID_REPLAY_TRUST_VECTOR | Replay Trust Vector computation |
| MEID_EXPORT_TG_FPACK | Prepare federation exchange package |
Responsibility overlap shall be avoided.
23. Constitutional Execution Chain
The canonical execution chain is:
Need
↓
Collect
↓
Observe
↓
Assure
↓
Understand
↓
Treat
↓
Exchange
TrustGate micro-engines primarily operate across:
- Observe;
- Assure;
- Understand;
- Exchange.
Some micro-engines may also support Treat through workflows, recommendations, and corrective actions.
24. Runtime Artifact Classes
Micro-engines may produce artifacts across four constitutional classes.
| Class | Purpose | Examples |
|---|---|---|
| Observational | Describe reality | CSI, USO |
| Assurance | Verify reality | TG-VRES, VEVID, TOID, TVID, TAID |
| Knowledge | Interpret reality | TIID, TG-INTEL |
| Exchange | Transport constitutional truth | TG-ATTEST, federation packages, replay packages |
Each engine shall declare which artifact classes it consumes and produces.
25. Constitutional Constraints
Every TrustGate engine and micro-engine shall satisfy the following constraints.
- Every engine shall have an EID.
- Every micro-engine shall have an MEID.
- Every implementation shall resolve to a CMI.
- Every runtime execution shall emit telemetry.
- Every replay-capable engine shall preserve deterministic replay.
- Every engine shall preserve canonical identifiers.
- Every engine shall satisfy applicable CIR invariants.
- Every engine shall remain lifecycle governed through CALM.
These constraints are normative.
26. Summary
The TrustGate Micro Engine Catalog establishes the constitutional foundation for TrustGate runtime execution.
By distinguishing EID, MEID, CMI, and CMID responsibilities, aligning micro-engines with CIA, CPA, CALM, and CIR, and defining their participation in validation, trust, attestation, replay, federation, telemetry, and intelligence, the catalog ensures that every TrustGate execution component remains identifiable, governed, observable, replayable, and explainable.
The following part defines the canonical micro-engine model, including engine metadata, capability declarations, dependency contracts, execution classes, and runtime responsibility profiles.
Part 2 — Canonical Micro Engine Model
27. Purpose
The Canonical Micro Engine Model defines the constitutional metadata required to describe every executable TrustGate micro-engine.
It establishes a common representation for engine identity, capability, execution contracts, governance, runtime behaviour, lifecycle, and interoperability.
Every governed micro-engine shall conform to this model regardless of implementation language, deployment architecture, or execution environment.
28. Constitutional Principle
A micro-engine is a governed computational capability.
It is not merely executable software.
Every micro-engine shall possess:
- constitutional identity;

The constitutional model is independent of implementation.
29. Canonical Identity
Every micro-engine possesses three constitutional identities.
| Identity | Purpose |

These constraints are normative.
46. Summary
The Canonical Micro Engine Model defines the constitutional blueprint for every executable TrustGate capability.
By standardizing identity, metadata, contracts, dependencies, runtime characteristics, observability, and governance, the model ensures that all micro-engines remain deterministic, explainable, replayable, interoperable, and constitutionally governed throughout their lifecycle.
The following part introduces the Runtime Execution Architecture, where these canonical micro-engine definitions are orchestrated into deterministic execution pipelines and constitutional workflows.
Part 3 — Runtime Architecture
47. Purpose
The Runtime Architecture defines how TrustGate micro-engines execute, collaborate, and exchange governed artifacts within the constitutional TrustGate ecosystem.
It specifies the runtime principles governing orchestration, execution boundaries, execution contexts, artifact flow, observability, replay readiness, and interoperability.
The Runtime Architecture governs execution behaviour rather than implementation technology.
48. Constitutional Principle
Runtime execution shall be deterministic.
Every execution step shall be:
- identifiable;
- observable;
- replayable;
- explainable;
- governed.
Hidden execution behaviour is prohibited.
Every runtime action shall be attributable to one or more governed micro-engines.
49. Runtime Layers
TrustGate runtime execution is organized into constitutional layers.
Constitutional Specifications
↓
Major Engines (EID)
↓
Micro Engines (MEID)
↓
Runtime Execution
↓
Governed Artifacts
↓
Telemetry
↓
Replay
Each layer has a clearly defined responsibility.
50. Major Engines
Major Engines (EIDs) represent orchestration domains.
Typical examples include:
| EID | Responsibility |
|---|---|
| TG-COLLECT | Signal acquisition |
| TG-OBSERVE | Signal processing and canonical observation |
| TG-ASSURE | Validation, trust and assurance |
| TG-UNDERSTAND | Intelligence generation |
| TG-TREAT | Workflow and remediation |
| TG-EXCHANGE | Federation and information exchange |
Major engines coordinate execution.
Micro-engines perform execution.
51. Micro-Engine Collaboration
Micro-engines collaborate through governed artifact exchange.
Micro-engines shall never invoke hidden internal behaviour.
Instead they exchange constitutional artifacts such as:
- CSI
- USO ID
- TG-VRES
- VEVID
- TOID
- TVID
- TAID
- TIID
Artifacts represent the constitutional contract between engines.
52. Runtime Execution Context
Every execution shall occur within an immutable execution context.
Typical context information includes:
- execution identifier;
- EID;
- MEID;
- CMI;
- tenant;
- E-C-O™ Number;
- policy version;
- execution timestamp;
- correlation identifier.
The execution context shall remain available throughout the execution lifecycle.
53. Runtime Execution Model
Micro-engines execute independently.
Execution may be:
- synchronous;
- asynchronous;
- event-driven;
- scheduled;
- streamed;
- orchestrated.
The execution model shall not affect constitutional behaviour.
54. Stateless Execution
Micro-engines should be stateless wherever possible.
State shall be persisted in governed registries rather than retained within executing components.
Benefits include:
- replayability;
- scalability;
- resilience;
- deterministic behaviour;
- horizontal scaling.
55. Runtime Artifact Exchange
Micro-engines communicate by exchanging governed artifacts.
Example:
Signal
↓
Canonical Signal
↓
Validation Result
↓
Validation Evidence
↓
Trust Object
↓
Trust Vector
↓
Attestation
↓
Trust Intelligence
Artifacts are immutable after publication.
56. Runtime Orchestration
Runtime orchestration coordinates multiple micro-engines into governed workflows.
Responsibilities include:
- dependency resolution;
- execution ordering;
- retry management;
- timeout handling;
- concurrency control;
- artifact routing;
- policy enforcement.
Orchestration shall remain independent of business logic.
57. Event-Driven Execution
Micro-engines may publish runtime events.
Examples include:
- Signal Received
- Validation Completed
- Trust Updated
- Attestation Published
- Replay Requested
- Federation Completed
- Intelligence Generated
Events enable loose coupling between execution components.
58. Runtime Isolation
Each micro-engine shall execute within a bounded responsibility context.
Isolation prevents:
- hidden side effects;
- uncontrolled dependencies;
- unpredictable execution;
- unintended state mutation.
Execution isolation supports replay and explainability.
59. Runtime Lineage
Runtime execution extends constitutional lineage.
MEID
↓
Execution
↓
Produced Artifact
↓
Telemetry
↓
Replay
Every execution step shall preserve lineage.
60. Runtime Telemetry
Every execution shall generate constitutional telemetry.
Minimum telemetry includes:
- execution identifier;
- MEID;
- EID;
- CMI;
- consumed artifacts;
- produced artifacts;
- execution duration;
- execution outcome;
- correlation identifier.
Telemetry shall be immutable.
61. Runtime Error Handling
Execution failures shall themselves become governed runtime artifacts.
Failures shall preserve:
- failure classification;
- originating MEID;
- execution context;
- policy references;
- telemetry references;
- replay eligibility.
Failures shall never invalidate historical lineage.
62. Runtime Security
Runtime execution shall preserve constitutional security.
Execution shall support:
- authentication;
- authorization;
- policy enforcement;
- cryptographic verification;
- secure artifact exchange;
- auditability.
Security policies shall remain externally governed.
63. Runtime Explainability
Every execution shall be explainable.
Explainability shall include:
- executing MEID;
- consumed artifacts;
- produced artifacts;
- applied policies;
- execution order;
- replay references.
Runtime behaviour shall never depend upon hidden logic.
64. Runtime Replay Readiness
Runtime execution shall preserve sufficient information for deterministic replay.
Replay readiness includes:
- execution context;
- artifact lineage;
- configuration;
- policy version;
- runtime telemetry;
- execution order.
Replay shall reconstruct execution without interpretation.
65. Runtime Governance
The Runtime Architecture is governed by:
| Framework | Responsibility |
|---|---|
| CIA | Identity |
| CPA | Persistence |
| CALM | Lifecycle |
| CIR | Constitutional invariants |
| Validation Rule Registry | Validation |
| Trust Model | Trust computation |
| Attestation Catalog | Assurance publication |
| Replay Specification | Deterministic replay |
Together these frameworks govern constitutional execution.
66. Constitutional Constraints
Runtime implementations shall satisfy the following requirements.
- Every execution shall reference an MEID.
- Every execution shall execute within an immutable execution context.
- Every produced artifact shall preserve lineage.
- Every execution shall emit telemetry.
- Runtime execution shall remain deterministic.
- Runtime execution shall remain replayable.
- Runtime execution shall satisfy constitutional invariants.
These constraints are normative.
67. Summary
The Runtime Architecture defines how TrustGate micro-engines collaborate to execute governed computational capabilities while preserving constitutional identity, lineage, observability, replayability, and interoperability.
By separating orchestration from execution, treating governed artifacts as the contracts between micro-engines, and ensuring every execution is deterministic and explainable, the architecture provides the foundation for scalable, replayable, and federated runtime behaviour across the ZAYAZ platform.
The following part introduces the Canonical Execution Pipeline (CEP), defining the constitutional sequence of runtime stages through which governed artifacts flow from collection to exchange.
Part 4 — Canonical Execution Pipeline (CEP)
68. Purpose
The Canonical Execution Pipeline (CEP) defines the normative runtime sequence through which constitutional artifacts flow inside the TrustGate architecture.
CEP governs execution order, artifact production, orchestration boundaries, and runtime lineage.
The pipeline is implementation independent.
Every conforming implementation shall preserve the constitutional behaviour defined by CEP.
69. Constitutional Principle
Execution transforms governed artifacts.
Execution never transforms constitutional identity.
Each stage:
- consumes governed artifacts;
- produces governed artifacts;
- preserves constitutional identity;
- extends lineage;
- emits telemetry;
- remains replayable.
The execution pipeline therefore represents constitutional evolution rather than data mutation.
70. Relationship to the Constitutional Intelligence Lifecycle
CEP operationalizes the Constitutional Intelligence Lifecycle (CIL).
Need
↓
Collect
↓
Observe
↓
Assure
↓
Understand
↓
Treat
↓
Exchange
CEP expands the runtime behaviour of the Observe, Assure, Understand, Treat, and Exchange capabilities into governed execution stages.
71. Canonical Execution Stages
The canonical TrustGate execution sequence is defined as follows.
| Stage | Constitutional Stage | Primary Responsibility | Primary Artifact |
|---|---|---|---|
| 1 | Signal Acquisition | Receive governed input | Raw Signal |
| 2 | Signal Parsing | Parse external payloads | Canonical Payload |
| 3 | Signal Normalization | Normalize identifiers, units, schemas | Normalized Signal |
| 4 | Metadata Enrichment | Attach CSI, USO, CMI, E-C-O™ Number, lineage | Enriched Signal |
| 5 | Identity Resolution | Resolve canonical identities | Governed Signal |
| 6 | Validation | Execute VRIDs | TG-VRES |
| 7 | Validation Evidence | Produce evidence | VEVID |
| 8 | Trust Evaluation | Produce trust artifacts | TOID / TVID |
| 9 | Decision | Determine runtime disposition | Decision Outcome |
| 10 | Attestation | Generate constitutional attestation | TAID / TG-ATTEST |
| 11 | Replay Registration | Preserve deterministic replay | Replay Package |
| 12 | DAL Anchoring | Anchor immutable references | DAL Reference |
| 13 | Federation | Exchange governed artifacts | Federation Package |
| 14 | Trust Intelligence | Produce intelligence | TIID / TG-INTEL |
Each stage extends the constitutional artifact chain without modifying historical artifacts.
72. Execution Stage Responsibilities
Every execution stage shall have a single constitutional responsibility.
Examples include:
| Stage | Responsibility |
|---|---|
| Parsing | Interpret external representations |
| Normalization | Canonicalize data |
| Validation | Evaluate compliance with VRIDs |
| Trust | Establish confidence |
| Attestation | Publish constitutional assurance |
| Replay | Preserve deterministic execution |
| Federation | Exchange constitutional truth |
| Intelligence | Generate explainable insight |
Responsibilities shall remain bounded.
73. Micro-Engine Participation
Execution stages are implemented by one or more micro-engines.
Example:
Execution Stage
↓
MEID A
↓
MEID B
↓
MEID C
↓
Produced Artifact
The number of participating micro-engines is implementation specific.
The constitutional stage remains invariant.
74. Artifact Flow
CEP governs constitutional artifact progression.
Signal
↓
CSI / USO
↓
TG-VRES
↓
VEVID
↓
TOID
↓
TVID
↓
TAID
↓
Replay
↓
Federation
↓
TIID
Historical artifacts remain immutable.
75. Execution Context
Every CEP execution occurs within a governed execution context.
The context shall include:
- Execution ID;
- EID;
- MEID;
- CMI;
- tenant;
- E-C-O™ Number;
- timestamps;
- policy version;
- correlation identifier.
The execution context persists throughout the pipeline.
76. Runtime Orchestration
CEP does not prescribe orchestration technology.
Execution may be:
- sequential;
- parallel;
- event-driven;
- workflow-based;
- message-driven;
- distributed.
Equivalent implementations remain constitutionally conformant.
77. Deterministic Behaviour
Given identical:
- inputs;
- policies;
- engine versions;
- configuration;
- identifiers;
CEP shall produce equivalent constitutional artifacts.
Determinism is mandatory.
78. Replay Compatibility
Every execution stage shall preserve sufficient information for deterministic replay.
Replay includes:
- execution order;
- consumed artifacts;
- produced artifacts;
- policy references;
- telemetry;
- runtime context.
Replay shall reconstruct constitutional behaviour without interpretation.
79. Runtime Telemetry
Every execution stage shall emit constitutional telemetry.
Minimum telemetry includes:
- Execution ID;
- MEID;
- stage;
- consumed artifacts;
- produced artifacts;
- execution status;
- duration;
- timestamps.
Telemetry forms part of the replay record.
80. Constitutional Constraints
Implementations of CEP shall satisfy the following requirements.
- Preserve constitutional identifiers.
- Preserve artifact lineage.
- Emit telemetry at every stage.
- Support deterministic replay.
- Produce immutable artifacts.
- Preserve explainability.
- Satisfy constitutional invariants.
- Maintain implementation independence.
These constraints are normative.
81. Summary
The Canonical Execution Pipeline (CEP) defines the constitutional runtime flow of TrustGate.
By separating constitutional execution stages from implementation-specific micro-engines, CEP establishes a deterministic, replayable, explainable, and technology-independent execution model. Every governed artifact progresses through a defined sequence of constitutional stages while preserving identity, lineage, provenance, and trust.
The following part introduces the Canonical Micro-Engine Registry, which defines how executable capabilities are catalogued, classified, versioned, and governed within the TrustGate architecture.
Part 5 — Canonical Micro-Engine Registry
82. Purpose
The Canonical Micro-Engine Registry is the authoritative registry of every governed executable capability within the TrustGate architecture.
The registry defines the constitutional identity, metadata, responsibilities, contracts, lifecycle, and operational characteristics of each micro-engine.
Every executable component participating in constitutional runtime execution shall be represented in the registry.
83. Constitutional Principle
Every executable capability shall be registered.
No executable constitutional behaviour shall exist outside the Canonical Micro-Engine Registry.
The registry is the constitutional source of truth for executable capabilities.
84. Registry Responsibilities
The registry governs:
- micro-engine identity;
- engine classification;
- execution responsibilities;
- artifact contracts;
- runtime capabilities;
- lifecycle state;
- versioning;

| Deterministic | Yes / No |
| Replayable | Yes / No |
| Idempotent | Yes / No |
| Parallel Execution | Yes / No |
| Federation Eligible | Yes / No |
These characteristics assist orchestration and governance.
89. Registry Relationships
Registry entries participate in constitutional relationships.
A micro-engine may reference:
- other MEIDs;
- CMI artifacts;
- VRIDs;
- CSI;
- USO Types;
- Trust Objects;
- Trust Vectors;
- Attestations;
- Replay artifacts.
Relationships define dependencies without introducing hidden execution behaviour.
90. Canonical Classification
Micro-engines shall be classified by constitutional capability.
Recommended categories include:
| Category | Purpose |
|---|---|
| Parsing | Interpret external representations |
| Transformation | Normalize and enrich |
| Identity | Resolve canonical identities |
| Validation | Execute validation rules |
| Evidence | Generate validation evidence |
| Trust | Compute trust artifacts |
| Decision | Apply trust policies |
| Attestation | Produce constitutional attestations |
| Replay | Preserve deterministic execution |
| Federation | Exchange constitutional artifacts |
| Intelligence | Generate governed intelligence |
| Utility | Shared runtime capabilities |
Additional categories may be introduced through governance.
91. Initial Constitutional Registry
The following table defines the initial first-class constitutional micro-engines.
| MEID | Parent EID | Canonical Responsibility |
|---|---|---|
MEID.TG.COLLECT.ACQUIRE | TG-COLLECT | Acquire governed signals |
MEID.TG.PARSE.SIGNAL | TG-OBSERVE | Parse external payloads |
MEID.TG.NORMALIZE.SIGNAL | TG-OBSERVE | Normalize identifiers, units and schemas |
MEID.TG.ENRICH.METADATA | TG-OBSERVE | Attach canonical metadata |
MEID.TG.RESOLVE.IDENTITY | TG-OBSERVE | Resolve CSI, USO and CMI references |
MEID.TG.VALIDATE.RULE | TG-ASSURE | Execute VRIDs |
MEID.TG.GENERATE.EVIDENCE | TG-ASSURE | Produce VEVID artifacts |
MEID.TG.COMPUTE.TRUST | TG-ASSURE | Produce Trust Objects and Trust Vectors |
MEID.TG.DECISION.ROUTER | TG-ASSURE | Apply constitutional decision policies |
MEID.TG.ATTEST.CREATE | TG-ASSURE | Generate TAIDs and TG-ATTEST artifacts |
MEID.TG.REPLAY.REGISTER | TG-ASSURE | Preserve deterministic replay state |
MEID.TG.DAL.ANCHOR | TG-EXCHANGE | Prepare cryptographic anchoring |
MEID.TG.FEDERATION.EXPORT | TG-EXCHANGE | Produce federation packages |
MEID.TG.INTELLIGENCE.GENERATE | TG-UNDERSTAND | Produce TIIDs and TG-INTEL artifacts |
These entries define constitutional responsibilities rather than implementation details.
92. Versioning
Every registry entry shall be independently versioned.
Versioning shall preserve:
- backward compatibility where possible;
- replay compatibility;
- deterministic execution;
- historical reproducibility.
Historical versions remain governed artifacts.
93. Lifecycle Governance
Registry entries participate in CALM.
Typical lifecycle states include:
Draft
↓
Approved
↓
Published
↓
Operational
↓
Deprecated
↓
Retired
Execution eligibility shall be determined by lifecycle state.
94. Registry Persistence
Registry information shall be persisted using the Canonical Persistence Architecture (CPA).
Implementations may use SQL, document databases, graph databases, or equivalent technologies provided constitutional behaviour is preserved.
95. Registry Telemetry
Runtime telemetry shall reference the responsible MEID.
Telemetry therefore establishes the execution lineage:
MEID
↓
Execution
↓
Telemetry
↓
Replay
↓
Trust Intelligence
Every execution becomes attributable to a governed registry entry.
96. Constitutional Constraints
The Canonical Micro-Engine Registry shall satisfy the following requirements.
- Every executable capability shall possess a unique MEID.
- Every MEID shall belong to exactly one EID.
- Every MEID shall resolve to a governed CMI.
- Every MEID shall declare constitutional responsibilities.
- Every MEID shall publish runtime contracts.
- Every MEID shall participate in CALM.
- Every MEID shall preserve replay compatibility.
- Every MEID shall satisfy applicable constitutional invariants.
These constraints are normative.
97. Summary
The Canonical Micro-Engine Registry provides the constitutional source of truth for executable capabilities within TrustGate.
By governing identity, responsibilities, runtime contracts, lifecycle, versioning, and operational characteristics, the registry ensures that every executable component remains identifiable, explainable, replayable, and interoperable.
Rather than cataloguing implementation-specific services, the registry defines constitutional execution capabilities that may be realized by one or more software components while preserving identical constitutional behaviour.
The following part introduces the Validation Integration Model, describing how registered micro-engines bind to Validation Rules (VRIDs), execute assurance policies, and produce governed validation artifacts.
Part 6 — Validation Integration Model
98. Purpose
The Validation Integration Model defines how TrustGate micro-engines participate in constitutional validation.
It specifies the relationship between executable capabilities, Validation Rules (VRIDs), validation evidence, assurance artifacts, telemetry, and replay.
This chapter establishes validation as a governed execution contract rather than an implementation detail.
99. Constitutional Principle
Micro-engines execute validation.
Validation Rules define validation.
The constitutional responsibilities are therefore separated:
Validation Rule Registry
↓
VRID
↓
Micro Engine (MEID)
↓
Execution
↓
TG-VRES
↓
VEVID
Rules govern behaviour.
Micro-engines perform execution.
100. Validation Responsibility
Validation shall always be performed by one or more governed micro-engines.
Each participating MEID shall declare:
- supported validation domains;
- supported VRID categories;
- execution capability;
- replay capability;
- evidence generation capability.
Validation responsibilities shall be explicitly declared.
101. Validation Binding
Validation occurs through constitutional binding.
MEID
↓
VRID
↓
Validation Execution
↓
TG-VRES
Bindings are explicit.
A micro-engine shall never execute undeclared validation rules.
102. Validation Execution Contract
Every validation-capable micro-engine shall publish an execution contract.
Minimum information includes:
| Property | Description |
|---|---|
| Supported VRIDs | Validation Rules executed |
| Input Artifacts | CSI, USO, TAID, etc. |
| Output Artifacts | TG-VRES, VEVID |
| Execution Mode | Sync, async, event-driven |
| Deterministic | Required |
| Replay Support | Required |
| Telemetry | Mandatory |
Execution contracts remain versioned constitutional metadata.
103. Validation Inputs
Validation engines may consume governed artifacts including:
- CSI;
- USO IDs;
- CMIDs;
- CMI references;
- TAIDs;
- TOIDs;
- TVIDs;
- policy references;
- configuration objects.
All inputs shall preserve constitutional identity.
104. Validation Outputs
Validation execution produces constitutional artifacts.
Typical outputs include:
TG-VRES
↓
VEVID
↓
Trust Objects
↓
Trust Vectors
↓
Attestations
Outputs remain immutable after publication.
105. Validation Evidence
Every constitutional validation shall generate replayable evidence.
Evidence may include:
- executed VRIDs;
- evaluated inputs;
- decision rationale;
- execution timestamps;
- policy versions;
- execution telemetry;
- replay references.
Evidence shall be uniquely identified by VEVID.
106. Validation Lifecycle
Validation execution follows a constitutional lifecycle.
Validation Requested
↓
Rule Resolution
↓
Execution
↓
Evidence Generation
↓
Result Publication
↓
Telemetry
↓
Replay Registration
Each stage extends constitutional lineage.
107. Validation Categories
Micro-engines may support one or more validation categories.
Examples include:
| Category | Purpose |
|---|---|
| Structural | Schema and syntax validation |
| Semantic | Business meaning validation |
| Identity | CSI, USO and CMI verification |
| Referential | Registry integrity |
| Computational | Formula validation |
| Policy | Governance compliance |
| Trust | Assurance evaluation |
| Federation | Exchange validation |
Categories are governed by the Validation Rule Registry.
108. Multi-Engine Validation
Validation may involve multiple cooperating micro-engines.
Example:
MEID Resolve Identity
↓
MEID Validate Structure
↓
MEID Validate Rules
↓
MEID Generate Evidence

Execution ordering is implementation specific.
Produced constitutional artifacts remain identical.
109. Validation Telemetry
Every validation execution shall emit telemetry.
Minimum telemetry includes:
- execution identifier;
- MEID;
- VRID;
- TG-VRES;
- VEVID;
- timestamps;
- duration;

- replay reference.
Telemetry supports constitutional observability.
110. Validation Explainability
Every validation shall remain explainable.
Explainability shall include:
- executed VRIDs;
- responsible MEIDs;
- input artifacts;
- generated evidence;
- decision rationale;

Validation decisions shall never rely upon hidden logic.
111. Replay Compatibility
Validation shall preserve deterministic replay.
Replay shall reconstruct:
- rule selection;
- execution order;
- policy versions;

112. Federation Compatibility
Validation artifacts exchanged through federation shall preserve:
- VRID;
- TG-VRES;
- VEVID;
- TAID;

Federated validation remains constitutionally equivalent to local validation.
##113. AI Participation
AI may assist validation.
AI assistance may include:
- anomaly detection;
- rule recommendations;
- confidence estimation;
- explainability generation;
- optimization suggestions.
AI shall not alter constitutional validation outcomes without governed policy authorization.

114. Constitutional Constraints
Validation integration shall satisfy the following requirements.
- Every validation shall reference one or more VRIDs.
- Every validation shall execute through governed MEIDs.
- Every validation shall produce TG-VRES.
- Every constitutional validation shall generate VEVID.
- Validation telemetry shall be mandatory.
- Validation shall remain deterministic.
- Validation shall support replay.
- Validation shall satisfy constitutional invariants.
These constraints are normative.
115. Summary
The Validation Integration Model establishes how TrustGate micro-engines execute constitutional validation while preserving identity, lineage, evidence, explainability, and replayability.
By separating validation rules from executable capabilities and binding them through governed execution contracts, the architecture enables scalable, deterministic, and federated validation across the ZAYAZ platform.
The following part introduces the Trust Integration Model, describing how validation outcomes are transformed into governed Trust Objects, Trust Vectors, Trust Status, and operational trust intelligence.
Part 7 — Trust Integration Model
116. Purpose
The Trust Integration Model defines how TrustGate micro-engines participate in constitutional trust computation.
It establishes how executable capabilities transform validation outcomes into governed trust artifacts while preserving constitutional identity, provenance, explainability, and deterministic replay.
This chapter separates trust computation from validation, ensuring that trust remains an independent constitutional capability built upon governed evidence.
117. Constitutional Principle
Validation determines whether something complies with defined rules.
Trust determines the confidence that may be placed in the resulting information.
These responsibilities shall remain independent.

118. Trust Responsibility
Trust-capable micro-engines shall declare their constitutional trust responsibilities.
Typical responsibilities include:
- trust computation;
- confidence estimation;
- evidence aggregation;
- trust policy evaluation;
- operational flag generation;
- trust lifecycle management.
Responsibilities shall be explicitly declared within the Canonical Micro-Engine Registry.
119. Trust Binding

121. Trust Outputs
Trust computation produces governed trust artifacts.
Typical outputs include:
| Artifact | Purpose |
|---|---|
| TOID | Trust Object |
| TVID | Trust Vector |
| Trust Status | Overall constitutional trust state |

Outputs are immutable constitutional artifacts.
122. Trust Object Generation
Trust Objects represent explainable trust evaluations.
Each TOID shall preserve:
- evaluated subject;
- originating validation results;
- contributing evidence;
- applied trust policies;
- producing MEID;
- execution context;

Trust Objects are the primary units of constitutional trust reasoning.
123. Trust Vector Generation
Trust Vectors summarize one or more Trust Objects into a governed trust profile.
A Trust Vector may include dimensions such as:
- completeness;
- consistency;
- provenance;
- timeliness;
- authenticity;
- evidence quality;
- federation confidence;
- replay confidence.
The Trust Vector model is governed by the Trust Model specification.
124. Trust Lifecycle
Trust artifacts participate in CALM.
Typical lifecycle:
Computed
↓
Verified
↓
Operational
↓
Superseded
↓
Archived
Historical trust artifacts shall remain available for replay and audit.
125. Multi-Engine Trust Computation
Trust evaluation may involve multiple cooperating micro-engines.
Example:
MEID Compute Evidence Quality
↓

↓
MEID Compute Trust Score
↓
MEID Aggregate Trust Vector
↓
MEID Publish Trust Status
Implementation details may vary.
Produced constitutional artifacts shall remain equivalent.
126. Trust Policies
Trust computation shall reference governed trust policies.
Policies may define:
- weighting models;
- evidence thresholds;
- confidence calculations;
- escalation criteria;
- operational tolerances;
- federation acceptance requirements.
Policies are external constitutional artifacts and shall not be embedded within executable code.
127. Operational Trust States
Trust computation may assign operational trust states.
Typical examples include:
| State | Meaning |
|---|---|
| Trusted | Suitable for normal processing |
| Provisionally Trusted | Accepted with defined limitations |
| Under Review | Additional evaluation required |
| Low Confidence | Significant uncertainty detected |
| Rejected | Trust requirements not satisfied |
Operational states support downstream orchestration but do not alter historical artifacts.
128. Trust Explainability
Every trust decision shall remain explainable.
Explainability shall include:
- originating TG-VRES;
- contributing VEVIDs;
- applied trust policies;
- generated TOIDs;

Replay shall reproduce constitutional trust behaviour without reinterpretation.
131. Federation Compatibility
Trust artifacts exchanged between ECOs shall preserve:
- originating TOIDs;
- originating TVIDs;
- originating TAIDs;
- provenance metadata;
- issuing E-C-O™ Number;
- replay references.
Receiving ECOs may evaluate foreign trust artifacts according to local trust policies while preserving their original constitutional identity.
132. AI Participation
AI may assist constitutional trust computation.
Permitted capabilities include:
- anomaly detection;
- confidence estimation;
- trust trend analysis;
- evidence correlation;
- explainability generation;
- optimization recommendations.
AI-generated outputs shall remain advisory unless explicitly authorized through governed policy.
AI shall never modify published constitutional trust artifacts.
133. Constitutional Constraints

These constraints are normative.
134. Summary
The Trust Integration Model defines how TrustGate micro-engines transform governed validation evidence into constitutional trust artifacts.
By separating validation from trust computation and ensuring that every Trust Object, Trust Vector, and Trust Status preserves provenance, explainability, telemetry, and replayability, the architecture establishes a transparent and extensible trust framework for the entire ZAYAZ platform.
The following part introduces the Attestation Integration Model, describing how governed trust artifacts are transformed into signed TG-ATTEST assurance artifacts suitable for federation, external assurance, and long-term constitutional verification.
